Embodiments of the Invention

[0008] Hereinafter, as an example of an embodiment of the present invention, an information processing system and an information processing method performed by the information processing system will be described with reference to the drawings.

[0009] <Supplement Regarding Tacit Knowledge> In industries such as civil engineering and architecture, BIM / CIM is being promoted for the purpose of addressing issues such as the declining birthrate and aging population, and improving labor productivity.

[0010] BIM stands for Building Information Modeling, and it is a solution for utilizing information in all stages of construction, from design and construction to maintenance and management, by using a database of buildings that adds attribute data such as cost, finishes, and management information to a three-dimensional digital model of a building created on a computer (hereinafter referred to as the 3D model).

[0011] CIM stands for Construction Information Modeling and is a solution for the civil engineering sector (including infrastructure such as roads, power, gas, and water) that was proposed following the example of BIM, which was being developed in the building sector. Similar to BIM, CIM aims to improve the efficiency and sophistication of the entire construction production system by sharing information among stakeholders, primarily using 3D models.

[0012] A crucial aspect of promoting BIM and CIM implementation is how to effectively utilize the BIM and CIM systems that have been constructed.

[0013] Specifically, 3D models restored using BIM and CIM can be used not only for design and construction purposes, but also for other tasks such as maintenance and site surveys. In other words, they can be used not only as design drawings, but also for other purposes such as recording information in the 3D model and sharing it with others.

[0014] Furthermore, since the work performed on the 3D model can be recorded as a log, if tacit knowledge can be extracted from this data, it can be effectively used for transferring skills from experienced personnel to younger ones. This is expected to lead to front-loading of operations and talent development.

[0015] Focusing on the transmission of tacit knowledge, the challenge lies not only in 3D models but also in 2D data (such as 3D spherical images and planar images), as mentioned above, in how to transmit tacit knowledge between different tasks and among users with varying levels of skill.

[0016] Specifically, because tacit knowledge is qualitative and difficult to quantify, even if an tacit knowledge model is generated from tacit knowledge, it is difficult to secure user trust in the tacit knowledge model, making it difficult to promote its use. For example, if the field of expertise of the tacit knowledge model differs from that of the user, no matter how excellent the tacit knowledge model is, it will have no value to the user. Similarly, if the knowledge level of the tacit knowledge model is lower than the user's knowledge level, it will have no value to the user.

[0017] However, it is also true that tacit knowledge models can give users new perspectives and insights, and by using tacit knowledge models, even inexperienced users have great potential to acquire know-how and skills and apply them to their work.

[0018] Furthermore, there are cases where the first and second servers manage related information. For example, the first server might hold property management information (such as captured images and audio text of the property), while the second server manages the property's three-dimensional image information. In this case, if a user logs in to the first server from a terminal device, they can view the property management information. On the other hand, if a user logs in directly to the second server from a terminal device, even if the second server can perform processing according to the property management information, it may not be appropriate to provide the processing results to the user.

[0019] For example, if a user logs in directly to the second server, it is unclear whether the user has the authority to log in to the first server. However, if the second server has a first tacit knowledge model obtained by learning from captured images of items, and the user is allowed to use the first tacit knowledge model when logging in directly to the second server, it would be providing processing to a user who does not have the authority to use it.

[0020] Therefore, in this embodiment, we will describe an information processing system that performs processing in response to a user logging into a first server and processing in response to a user logging into a second server.

[0021] <About Terminology> A user is someone who uses the text information (or other content such as images) generated by the tacit knowledge model. A data provider is someone who provides the data (such as audio information, text information, operation information, images, 3D data, etc.) that the tacit knowledge model uses for training.

[0022] Tacit knowledge is knowledge based on an individual's experience, intuition, etc. An tacit knowledge model is a model that learns tacit knowledge and outputs answers based on that learned tacit knowledge in response to questions. A model is a mechanism or artificial intelligence (AI) that learns the correspondence between input data and output data and outputs output data for given input data. Note that the output data does not depend on whether or not there is training data.

[0023] A property can be any space where items can be placed, such as a facility or a room within a facility. Items are things that are placed in the property. The types of items placed will vary depending on the function of the facility.

[0024] For example, properties include real estate, factories, construction sites, research facilities, medical facilities, farmland, warehouses, and equipment requiring maintenance. Goods include furniture, materials, equipment, heavy machinery, tools, instruments, materials, cultured products, and food.

[0025] The object is an object that is photographed by a photographic device, and whose state can be managed primarily by recording it as an image. In this embodiment, it will be described using the term "article." The object is, for example, placed on a property.

[0026] Three-dimensional image information of an object is an image of a 3D model captured by a virtual camera. The user can change the viewpoint of the three-dimensional image information.

[0027] Generated information is information generated based on three-dimensional image information and captured images. Generated information may be generated by an implicit knowledge model. In this embodiment, generated information is described using the terms implicit knowledge comments or text information.

[0028] A display screen is, for example, a screen that shows a captured image and 3D image information, or generated information and 3D image information, all on the same screen.

[0029] A wide-field image is an image with a wide field of view that includes areas that cannot be seen with a normal field of view. For example, a wide-field image is an image with a wide field of view that is captured with a wide shooting range, including a 360-degree image (also called a spherical image, omnidirectional image, or all-around image) that captures the entire 360 ​​degrees.

[0030] A predetermined region image is an image corresponding to a predetermined region within a wide-field image. The predetermined region image is projected onto a two-dimensional plane and is therefore a planar image. In this embodiment, the predetermined region image is saved by a capture operation and is therefore called a captured image.

[0031] The first process is updating the first tacit knowledge model or generating text information using captured images, and the second process is updating the second tacit knowledge model or generating text information without using captured images (using input information). The third process is a function that only the three-dimensional image management server 40 has, such as simulation.

[0032] [First Embodiment] <Example System Configuration> Figure 1 is an overall configuration diagram of an information processing system 100 according to an embodiment of the present invention. The information processing system 100 of this embodiment includes a terminal device 10, a three-dimensional image management server 40, and a captured image management server 20, which are examples of input / output devices. However, the terminal device 10 may be connected to the three-dimensional image management server 40 or the captured image management server 20 as needed, and is not required to be included in the information processing system 100.

[0033] The three-dimensional image management server 40 (an example of a second server) is one or more information processing devices that can communicate with the terminal device 10 via a communication network N. The three-dimensional image management server 40 manages three-dimensional image information of objects and also has an implicit knowledge model and a large-scale language model. The three-dimensional image management server 40 uses these to return text information containing implicit knowledge to the user. The three-dimensional image management server 40 may be a web server that returns processing results to the terminal device 10 in response to requests from the terminal device 10. A server is a computer or software that performs the function of providing information and processing results in response to requests from a client.

[0034] The 3D image management server 40 may support cloud computing. Cloud computing refers to a usage model in which network resources are utilized without being aware of specific hardware resources. Cloud computing can take the form of SaaS (Software as a Service), PaaS (Platform as a Service), or IaaS (Infrastructure as a Service), and any of these forms is acceptable. Therefore, the 3D image management server 40 does not need to be housed in a single enclosure or provided as a single unit of equipment. The functions of the 3D image management server 40 may be distributed among multiple information processing devices, or multiple information processing devices may each have all the functions, and the information processing device may be switched by load balancing or other means.

[0035] Furthermore, instead of the three-dimensional image management server 40 having an implicit knowledge model and a large-scale language model, the three-dimensional image management server 40 may call an API (Application Programming Interface) exposed by an external system and utilize at least one of the implicit knowledge model or the large-scale language model.

[0036] The image capture management server 20 (an example of the first server) is one or more information processing devices that can communicate with the terminal device 10 via the communication network N. The image capture management server 20 manages property management information. Property management information is, for example, a string of characters such as text. The image capture management server 20 does not have three-dimensional image information. The image capture management server 20 can distribute live images of wide-field images captured by the camera 5. The image capture management server 20 also manages captured images captured by users. The image capture management server 20 is a server that allows users to manage the progress of construction work on a property and the placement of items while viewing video data of the property.

[0037] The captured image management server 20 may be a web server that returns processing results to the terminal device 10 in response to requests from the terminal device 10. The captured image management server 20 can communicate with the three-dimensional image management server 40 via the communication network N. The captured image management server 20 may also support either cloud computing or on-premises deployment.

[0038] Terminal device 10 is a general-purpose information processing terminal used by users of the information processing system 100. Terminal device 10 runs a web browser and a dedicated native application for the 3D image management server 40 or the captured image management server 20. When terminal device 10 runs a web browser, terminal device 10 and the 3D image management server 40 or the captured image management server 20 run a web application. A web application is an application that operates through the cooperation of a program written in a programming language (e.g., JavaScript®) that runs on a web browser and a program on the web server (3D image management server 40). When a web application is executed, the processing of this embodiment may be performed by the 3D image management server 40 or the captured image management server 20, or by terminal device 10 that receives the web application.

[0039] An application that cannot be executed unless it is installed on the terminal device 10 is called a native application. In this embodiment as well, the application executed on the terminal device 10 may be either a web application or a native application. In this case as well, the processing in this embodiment may be performed by the three-dimensional image management server 40 or by the terminal device 10 that is executing the native application.

[0040] Terminal device 10 can be, for example, a PC (Personal Computer), a smartphone, a PDA (Personal Digital Assistant), or a tablet device. Alternatively, terminal device 10 can be any device capable of running a web browser or native applications. Terminal device 10 may also be an electronic whiteboard, a television receiver, a glasses device, or a wearable device. Furthermore, there may be multiple terminal devices 10.

[0041] The terminal device 10 can communicate with the three-dimensional image management server 40 and the captured image management server 20 via the communication network N. The communication network N is constructed using the Internet, LAN (Local Area Network), provider services, etc. The communication network N may include not only wired communication but also mobile communication networks such as 3G (3rd Generation), WiMAX (Worldwide Interoperability for Microwave Access), LTE (Long Term Evolution), and wireless LAN networks. Furthermore, the terminal device 10 can communicate using short-range communication technologies such as Bluetooth (registered trademark) and NFC (registered trademark, Near Field Communication).

[0042] The imaging device 5 is a digital camera for obtaining wide-field images and recording sound. The imaging device 5 is connected to the communication network N via the relay device 3. The relay device 3 has the function of a cradle for charging the imaging device 5 and transmitting and receiving data. In addition, the relay device 3 can communicate data with the imaging device 5 via contacts and can also communicate data with the captured image management server 20 via the communication network N. The imaging device 5 and the relay device 3 are installed at predetermined locations on site Sa, such as construction sites, exhibition halls, educational institutions, and medical facilities. The imaging device 5 may be a general digital camera that obtains narrow-field images, such as a single-lens reflex camera, and the captured image management server 20 may distribute live images of the narrow-field images captured by the imaging device 5. In this case, the predetermined area image is an image corresponding to all or part of a predetermined area of ​​the captured image.

[0043] In Figure 1, the 3D image management server 40, the captured image management server 20, and the terminal device 10 communicate via the communication network N. However, users may also operate the 3D image management server 40 or the captured image management server 20 directly from a console.

[0044] <Example Hardware Configuration> Figure 2 is a hardware configuration diagram of the three-dimensional image management server 40, the captured image management server 20, or the terminal device 10 according to this embodiment.

The communication I / F 107 is an interface used for communication with other devices.

[0050] If the terminal device 10 is a glass device, the terminal device 10 may use a circuit that displays an image on a lens or the like, which is a transmissive reflective material, instead of the display I / F 106.

[0051] Communication I / F107 is, for example, a NIC (Network Interface Card) that supports TCP (Transmission Control Protocol) / IP (Internet Protocol).

[0052] Furthermore, the terminal device 10 is equipped with a sensor I / F 108, an audio input / output I / F 109, an input I / F 110, a media I / F 111, and a DVD-RW (Digital Versatile Disk Rewritable) drive 112.

[0053] The sensor interface 108 is an interface for receiving detection information from various sensors. The sound input / output interface 109 is a circuit that processes the input and output of sound signals between the speaker 109a and the microphone 109b according to the control of the CPU 101. The input interface 110 is an interface for connecting a predetermined input means to the terminal device 10.

[0054] Keyboard 110a is a type of input device equipped with multiple keys for inputting characters, numbers, various instructions, etc. Mouse 110b is a type of input device used for selecting and executing various instructions, selecting processing targets, moving the cursor, and operating on the display screen, etc.

[0055] The media interface 111 controls the reading or writing (storage) of data to or from a recording medium 111a such as flash memory. The DVD-RW drive 112 controls the reading or writing of various types of data to or from a DVD-RW 112a, which is an example of a removable recording medium. Note that the DVD-RW may be a DVD-R or the like. The DVD-RW drive 112 may also be a Blu-ray drive that controls the reading or writing of various types of data to or from a Blu-ray Disc (registered trademark).

[0056] Furthermore, the terminal device 10 is equipped with a bus line 113. The bus line 113 is an address bus, data bus, etc., for electrically connecting each component such as the CPU 101.

[0057] Furthermore, recording media such as HDs and CD-ROMs on which the above programs are stored can be provided domestically or internationally as program products. The terminal device 10 realizes the information processing method according to the present invention by executing, for example, the program according to the present invention.

[0058] <About the features> Figure 3 is an example of a functional configuration diagram illustrating the functions of the three-dimensional image management server 40, the captured image management server 20, and the terminal device 10 in the information processing system 100 according to this embodiment.

The decision unit 48 determines to use the first tacit knowledge model 4004A if the user logs in to the three-dimensional image management server 40 via the captured image management server 20. The decision unit 48 determines to use the second tacit knowledge model 4004B if the user logs in to the three-dimensional image management server 40 directly.

[0076] The measurement unit 51 is implemented by instructions from the CPU 401 shown in Figure 2, and measures the distance between two points specified by the user.

[0077] The simulation unit 52 is implemented by instructions from the CPU 401 shown in Figure 2, and executes pre-configured simulations on an object or item. The simulations include various types, such as predicting airflow within an object, predicting the size of items within an object (e.g., whether they can be brought in or installed), counting the number of items, or calculating the volume of a space.

[0078] The storage / reading unit 49 is an example of a storage control means and is executed by instructions from the CPU 401 shown in Figure 2, as well as by the HD 404, media I / F 411, and DVD-RW drive 412. It performs processing such as storing various data in the storage unit 4000, recording media 411a, and DVD-RW 412a, and reading various data from the storage unit 4000, recording media 411a, and DVD-RW 412a. The storage unit 4000, recording media 411a, and DVD-RW 412a are examples of storage means.

[0079] The memory unit 4000 contains a three-dimensional image information management DB 4001, a model shape management DB 4002, a caption model 4003, a first tacit knowledge model 4004A, a second tacit knowledge model 4004B, and a large-scale language model 4005.

[0080] The 3D image information management DB 4001 manages 3D image information related to the property. This 3D image information is information that visually represents the items (also called models) placed on the property. The model shape management DB 4002 manages the 3D model shape information of the items placed on the property. The 3D image management server 40 can generate 3D image information related to the property from the 3D model shape information. The 3D model shape information is information that depicts the item in 3D, such as a 3D model of the item or a 3D point cloud. The 3D model shape information may be composed of polygons or CAD data. In addition, the 3D image information management DB 4001 or the model shape management DB 4002 may store wide-field images such as 360-degree spherical images of the property.

[0081] Caption model 4003 is a model that is generated by performing a training process using image and caption comment combinations as training data, and enables a computer to function to output caption comments based on images. Caption comments are explicit knowledge and are used as a term in contrast to tacit knowledge. Here, caption comments are text data, such as comments expressed in audio or text that describe an image. Caption comments relating to objects or articles are associated with the identification information of those objects or articles.

[0082] The first tacit knowledge model 4004A is generated by performing a learning process using the correspondence between three-dimensional image information and captured images and the tacit knowledge (input information, speech text, etc.) associated with this three-dimensional image information and captured images as training data, and is a model that makes the computer function to output tacit knowledge comments based on images. The tacit knowledge model 4004 learns by associating information as follows. • Correspondence between three-dimensional image information and captured images and input information • Correspondence between three-dimensional image information and captured images and audio text. Correspondence between three-dimensional image information and captured images, and audio text and input information. Here, tacit knowledge comments are text data, and are comments expressed in audio or text, excluding caption comments, that is, comments relating to content not represented in the image.

[0083] The second tacit knowledge model 4004B does not use captured images for training. In other words, the second tacit knowledge model 4004B is generated by performing a training process using the correspondence between three-dimensional image information of an item and input information as training data, and it is a model that makes the computer function to output tacit knowledge comments based on the three-dimensional image information.

[0084] The large-scale language model 4005 is a computer language model that is generated by performing a training process using a vast amount of unlabeled text as training data and consists of an artificial neural network with many parameters. The large-scale language model 4005 can capture much of the syntax and meaning of human language by being sufficiently trained with context-learning techniques such as next sentence prediction, which understands context by determining whether sentence 1 and sentence 2 are consecutive, and the masked language model, which understands context by masking words in a sentence and predicting the masked words from the words before and after them.

[0085] <<Three-dimensional image information management table>> Figure 4 is a conceptual diagram showing an example of a three-dimensional image information management table according to this embodiment. The storage unit 4000 has a three-dimensional image information management DB 4001 constructed, which is composed of the three-dimensional image information management table shown in Figure 4. In the three-dimensional image information management table shown in Figure 4, the model ID, location information, and captured image are associated and managed in relation to the property identification information.

[0086] Property identification information is an example of property identification information used to identify a property. A property can be any space where goods can be placed, such as a facility or a room within a facility. The types of goods placed will vary depending on the function of the facility. A property can be represented in an easily manageable unit, such as "○○ Building 2F-N (the north side of the 2nd floor of ○○ Building)."

[0087] A Model ID is an example of identification information used to identify items placed in a property. The items may consist of three-dimensional model shape information, such as polygons or CAD data, in the Model Shape Management DB4002. The Model ID links the three-dimensional image information to the three-dimensional model shape in the Model Shape Management DB4002.

[0088] Location information is information that indicates the position of an item's model in a three-dimensional virtual space, where the item is represented in a virtual space, using three-dimensional coordinates (XYZ). For example, location information is indicated by the three-dimensional coordinates of eight points that define the rectangular space occupied by the model.

[0089] This location information is determined as the location information (latitude, longitude, and altitude) of the relay device 3 by GNSS (Global Navigation Satellite System) satellites such as GPS (Global Positioning Systems), or by IMES (Indoor Messaging System) as an indoor GPS. Indoor positioning methods include Wi-Fi positioning, RFID (Radio Frequency Identifier) ​​positioning, beacon positioning, pedestrian autonomous navigation positioning, geomagnetic positioning, acoustic positioning, and UWB (Ultra Wide Band) positioning.

[0090] The captured image is a captured image (two-dimensional image) obtained from the captured image management server 20. Capture means that a still image of a specific moment has been captured. The captured image is an image in which a predetermined area, specified by the field of view, has been cropped from the wide-field image captured by the shooting device 5. The reason why the captured image is registered in association with an item is that the three-dimensional image information is composed of a 3D model. When a user clicks on an item in the three-dimensional image information, the item (model ID) is identified by its coordinates. Alternatively, the three-dimensional image management server 40 may determine the position and field of view of the virtual camera based on the position information and field of view information of the shooting device 5 in the live image, and identify the model of the item that falls within the field of view from this position. The three-dimensional image management server 40 associates the captured image with the model ID of the identified item. Therefore, the captured image may contain an item.

[0091] The location information in Figure 4 is managed in correspondence with absolute positions on Earth. For example, by associating the origin of the location information in Figure 4 (X=0, Y=0, Z=0) with absolute positions on Earth (latitude, longitude, altitude), all coordinates in three-dimensional images, including three-dimensional models and objects, are associated with absolute positions on Earth.

[0092] In addition to these, instruction manuals, daily reports, quotations, drawings, etc., may also be registered in the three-dimensional image information management table.

[0093] <Functional configuration of the image management server> Let's return to Figure 3 for explanation. The captured image management server 20 has a transmitting / receiving unit 21, a screen generation unit 22, and a storage / reading unit 29. Each of these units is a function or means of functioning that is realized by any of the components shown in Figure 2 operating according to instructions from the CPU 401 that follow a program deployed from the HD 404 onto the RAM 403. The captured image management server 20 also has a storage unit 2000 constructed from the HD 404 shown in Figure 2. The storage unit 2000 is an example of a storage means.

[0094] In Figure 3, all functions are installed in a single image management server 20, but the image management server 20 may also be configured to distribute each function across multiple computers.

[0095] The transmitting / receiving unit 21 is an example of a transmitting or receiving unit, and is implemented by commands from the CPU 401 shown in Figure 2 and the communication I / F 407, and transmits and receives various data (or information) with other terminals, devices, or systems via the communication network N.

[0096] The screen generation unit 22 is an example of a screen generation means and is implemented by instructions from the CPU 401 shown in Figure 2, generating various screens. When the terminal device 10 runs a web application, screen information is created using HTML, XML, CSS, and JavaScript (registered trademark), etc. Therefore, screen information may also be referred to as a web application. When the terminal device 10 runs a client application, the screen information is held by the terminal device 10, and the information to be displayed is transmitted in XML, etc.

[0097] The storage / reading unit 29 is an example of a storage control means and is executed by instructions from the CPU 401 shown in Figure 2, as well as by the HD 404, media I / F 411, and DVD-RW drive 412. It performs processing such as storing various data in the storage unit 2000, recording media 411a, and DVD-RW 412a, and reading various data from the storage unit 2000, recording media 411a, and DVD-RW 412a. The storage unit 2000, recording media 411a, and DVD-RW 412a are examples of storage means.

[0098] <<Image Information Management Table>> Figure 5 is a conceptual diagram showing an example of an image capture information management table according to this embodiment. The memory unit 2000 has an image capture information management DB 2001 constructed, which is composed of an image capture information management table as shown in Figure 5.

[0099] In this image information management table, live images and captured images are recorded in association with property identification information. In the image information management table, the date and time of "shooting and sound collection", shooting location, field of view information, current date and time audio text (shooting device), and current date and time audio text (communication terminal) are stored and managed in association with the property identification information. The position of shooting device 5 was determined by the relay device 3 to which shooting device 5 is attached. Alternatively, shooting device 5 may determine its own position. • The "Capture and Sound Collection" date and time indicates the date and time of the live image captured and sound collected by the capture device 5. In the diagram, the live image is captured every second, but it may also be captured at 30fps or other rates. The shooting position indicates the position of the shooting device 5 (absolute position on Earth) when the wide-field image is captured. As will be described later, a terminal used to view live images in a meeting, etc., is called a communication terminal, and the operation in which a user of the communication terminal saves a captured image of the field of view they wish to save from the wide-field image is called a capture image. The image saved by the capture operation is called a captured image. This captured image is sent to the three-dimensional image management server 40. The shooting position is also the sound collection position. The field of view information is information used to identify a predetermined area displayed by the communication terminal when the user performs the capture operation from the wide-field image. The audio text registered in the "Current Time Audio Text (Capture Device)" field is text data converted by speech recognition from audio collected by the capture device 5. The audio text is comment data about items spoken by meeting participants while viewing the live image. The audio text registered in the "Current Time Audio Text (Communication Terminal)" field is text data converted by speech recognition from the speech of participants viewing live images on their communication terminals. The audio text is comment data about items spoken by meeting participants while viewing live images.

[0100] <Sending content data> Figure 6 is a sequence diagram showing the communication processing of wide-field images and audio data. In this embodiment, we will describe the case where the imaging device 5, participant A's communication terminal 9a, and participant B's communication terminal 9b are participating in the same remote communication. Steps S301 to S304 in Figure 6 are repeated.

[0101] S301: The camera 5 captures images of the surroundings and collects sound, sending video data (wide-field image) and audio data to the relay device 3. The camera 5 also transmits a device ID to identify the camera 5 in order to identify the property. As a result, the relay device 3 acquires the video data and audio data. The captured image management server 20 has pre-associated device IDs with properties.

[0102] S302: The relay device 3 transmits the acquired video data, audio data, and device ID to the captured image management server 20 via the communication network N. As a result, the transmitting / receiving unit 21 of the captured image management server 20 receives the video data, audio data, and device ID. The captured image management server 20 identifies the object by the device ID. As a result, the live image and the date and time of capture and sound collection are saved, for example, every second by the storage / reading unit 29 in the captured image information management DB 2001. Note that the live image may not be stored and only distributed. The captured image management server 20 (or an existing speech recognition server) uses the audio data to convert the audio portion into text data (hereinafter referred to as speech text). The storage / reading unit 29 saves the speech text in the captured image information management DB 2001.

[0103] S303a: The captured image management server 20 reads the participant IDs of those participating in the same conference as the camera 5 from the conference information. The captured image management server 20 also reads the IP addresses of the communication terminals 9a and 9b based on the read participant IDs. The captured image management server 20 refers to the IP address of communication terminal 9a and transmits the received video data and audio data to communication terminal 9a. As a result, communication terminal 9a receives the video data and audio data, displays the wide-field image, and outputs sound.

[0104] S303b: Similarly, the captured image management server 20 refers to the IP address of the communication terminal 9b and sends video data and audio data to the communication terminal 9b. As a result, the communication terminal 9b displays the wide-field image and outputs sound.

[0105] S304a, 304b: Meanwhile, communication terminals 9a and 9b transmit audio data from participants A and B to the captured image management server 20. This audio data is generated when microphones capture the voices of participants A and B operating the communication terminals 9a and 9b and convert them into audio data. The storage and reading unit 29 of the captured image management server 20 stores the audio text in the captured image information management DB 2001.

[0106] S305: Participants in communication terminals 9a and 9b can change the viewpoint of the video data, which is a wide-field image. If participant B wants to save a predetermined area of ​​the wide-field image displayed after changing the viewpoint, participant B can perform a capture operation at any time. Upon receiving the capture operation, communication terminal 9b sends a capture request and field-of-view information indicating the predetermined area currently displayed on the display to the captured image management server 20.

[0107] S306: When the captured image management server 20 receives a capture request and field of view information, it identifies the IP address of the relay device 3 which is participating in the same conference as the communication terminal 9b, and sends the capture request and field of view information to it.

[0108] S307: Relay device 3 receives the capture request and field of view information and transmits it to the shooting device 5.

[0109] S308: When the imaging device 5 receives a capture request, it generates a captured image based on the field of view information. The imaging device 5 transmits the captured image, shooting position, and field of view information to the relay device 3.

[0110] S309: The relay device 3 transmits the captured image, shooting location, and field of view information to the captured image management server 20. The captured image management server 20 identifies the property by the device ID, similar to step S303. The storage / reading unit 29 stores the captured image, shooting location, and field of view information in the captured image information management DB 2001.

[0111] Through the above process, the captured image information management DB2001 stores wide-field images (live images) and audio data in real time. If a participant performs a capture operation, the captured image, shooting location, and field of view image are also saved.

[0112] In Figure 6, the camera 5 generates a captured image in response to a request from the communication terminal 9b. However, the communication terminal 9b may generate a captured image of a predetermined area that it is currently displaying and send it to the captured image management server 20.

[0113] <An example of model updating and text information generation> Refer to Figures 7 and 8 to explain how to update the model and generate text information. In Figures 7 and 8, captured images and audio text are not used for updating the model and generating text information, but similar learning can be achieved by replacing or adding dialogue Q1, etc., with audio text.

[0114] Figure 7 is an explanatory diagram of what the terminal device 10 displays during the text information generation process and the model update process. Figure 7(a) is an explanatory diagram of the model update process. The display control unit 13 of the terminal device 10 displays the display screen 900 received from the three-dimensional image management server 40 on the display 106a, and the display screen 900 includes the target image 1100 and text 1200.

[0115] The input receiving unit 12 of the terminal device 10 receives audio information from the microphone 109b, which represents the dialogue Q1, A1, Q2, and A2 between data providers M1 and M2, as input information to be entered by the data provider into the displayed screen 900. It is preferable that data providers M1 and M2 have extensive knowledge, including tacit knowledge, about their work. Through such a dialogue between data providers M1 and M2, the tacit knowledge model is updated, allowing the user to obtain useful tacit knowledge comments.

[0116] The identification unit 44 identifies the target image 1100, which is the portion of the display screen 900 excluding the text 1200.

[0117] The judgment unit 43 then uses the target image 1100 to determine the degree of relevance between the caption comments obtained from the caption model 4003 and the dialogues Q1, A1, Q2, and A2.

[0118] The update unit 46 updates the tacit knowledge model by using comments from the dialogues Q1, A1, Q2, and A2 that are judged to have a low degree of relevance as tacit knowledge comments, along with the target image 1100, etc., as training data, and updates the caption model 4003 by using comments that are judged to have a high degree of relevance as caption comments, along with the target image 1100, as training data.

[0119] Therefore, the tacit knowledge model learns the correspondence between the target image 1100 and the dialogues Q1, A1, Q2, and A2. The target image 1100 has features extracted using several feature extraction models suitable for images, such as a CNN (Convolutional Neural Network). These features represent, for example, what is depicted and where, or the tasks being performed within the image. Thus, the tacit knowledge model can learn the correspondence between the image features and the dialogues Q1, A1, Q2, and A2.

[0120] Figure 7(b) is an explanatory diagram of the text information generation process. The display control unit 13 of the terminal device 10 displays the display screen 900 received from the three-dimensional image management server 40 on the display 106a, and the display screen 900 includes an image 1110 and text 1210.

[0121] The input receiving unit 12 of the terminal device 10 receives audio information indicating questions Q11 and Q12 from user M3 via the microphone 109b as input information to be entered by the user on the displayed screen 900.

[0122] The identification unit 44 identifies the image 1110 that does not contain the text 1210 as the target image.

[0123] The text information generation unit 45 uses image 1110 to acquire tacit knowledge comments based on the tacit knowledge model. The tacit knowledge model extracts features from image 1110 and determines that the features of image 1110 in Figure 7(b) are similar to those of image 1110 at the time of update, thereby identifying dialogues Q1, A1, Q2, and A2 related to image 1110. Dialogues Q1, A1, Q2, and A2 become tacit knowledge comments.

[0124] Furthermore, the text information generation unit 45 uses tacit knowledge comments (dialogue Q1, A1, Q2, A2) and questions Q11, Q12, etc., to generate text information related to the answers A11 and A12 to questions Q11 and Q12, respectively, based on the large-scale language model 4005.

[0125] The display control unit 13 of the terminal device 10 displays the text information related to the answers A11 and A12 received from the three-dimensional image management server 40 on the display 106a.

[0126] Figure 8 is another explanatory diagram displayed by the terminal device 10 during the model update process and text information generation process according to this embodiment. Figure 8 illustrates a case in which no question text is used during model update and text information generation.

[0127] Figure 8(a) is an explanatory diagram of the model update process. Figure 8(a) shows an example in which the tacit knowledge model is updated with audio information and partial images from a single data provider, rather than a conversation between data providers.

[0128] The display control unit 13 of the terminal device 10 displays the display screen 900 received from the three-dimensional image management server 40 on the display 106a, and the display screen 900 includes a first image 1100A and a second image 1100B.

[0129] The input receiving unit 12 of the terminal device 10 receives character information from the keyboard 110a, which represents comments C1 to C4 from data provider M4, as input information to be entered by the data provider in response to the displayed screen 900.

[0130] Furthermore, the input receiving unit 12 receives operation information from the mouse 110b, which indicates an operation by the data provider M4 to identify a partial image 1100B1 in the second image 1100B, as input information to be entered by the data provider M4 into the displayed screen 900.

[0131] The identification unit 44 may identify the partial image 1100B1 as the target image, or it may identify the first image 1100A or the second image 1100B as the target image.

[0132] The judgment unit 43 then uses the target image to determine the degree of relevance between the caption comments obtained from the caption model 4003 and comments C1 to C4.

[0133] The update unit 46 updates the tacit knowledge model by using comments C1 to C4 that are judged to have low relevance as tacit knowledge comments, along with partial image 1100B1, etc., as training data, and updates the caption model 4003 by using comments that are judged to have high relevance as caption comments, along with partial image 1100B1, as training data.

[0134] Therefore, the tacit knowledge model learns the correspondence between the partial image 1100B1 and the comments C1-C4. Features are extracted from the partial image 1100B1 using several feature extraction models suitable for images, such as CNNs. These features represent, for example, what is depicted and where, or the work being performed. Thus, the tacit knowledge model can learn the correspondence between the image features and the comments C1-C4.

[0135] Figure 8(b) is an explanatory diagram of the text information generation process. The display control unit 13 of the terminal device 10 displays the display screen 900 received from the three-dimensional image management server 40 on the display 106a, and the display screen 900 includes the image 1110.

[0136] User M5 does not input anything to the displayed screen 900, and the input reception unit 12 does not accept any input information from the user to the displayed screen 900. The identification unit 44 identifies the entire displayed screen 900, which is image 1110, as the target image.

[0137] When user M5 performs an operation to identify a partial image 1100B1 on the display screen 900, the input receiving unit 12 receives operation information from the mouse 110b indicating the operation to identify the partial image as input information. In this case, the identification unit 44 identifies the partial image on the display screen 900 as the target image according to the operation information.

[0138] The text information generation unit 45 uses the partial image 1100B1 to acquire tacit knowledge comments based on the tacit knowledge model. The tacit knowledge model determines that the features of image 1110B1 in Figure 8(b) are similar to those of image 1110B1 at the time of update, and can identify comments C1 to C4 related to image 1110B1. The tacit knowledge model extracts comments C1 to C4 as tacit knowledge comments. The text information generation unit 45 generates text information related to comments C11 to C14 based on the large-scale language model 4005, using tacit knowledge comments and the like. The text information generation unit 45 may generate text information using preset standard questions if no question text is entered, rather than using a method that does not use any questions at all.

[0139] The display control unit 13 of the terminal device 10 displays the text information related to comments C11 to C14 received from the three-dimensional image management server 40 on the display 106a.

[0140] <Action or process> <<Login to the 3D image management server via the captured image management server>> First, we will explain the case where a user measures the distance between two points in the three-dimensional image information of a property. The user may log in to the three-dimensional image management server 40 via the captured image management server 20, or they may log in directly to the three-dimensional image management server 40. Regardless of how the user logs in, the measurement results are the same.

[0141] Referring to Figure 9, we will explain the case where a user logs in to the three-dimensional image management server 40 via the captured image management server 20. Figure 9 is a sequence diagram showing an example of a measurement process in which a user requests the three-dimensional image management server 40 to measure the distance between two points on an object or property.

[0142] S1: The user enters a login operation into the terminal device 10. This login is for the captured image management server 20. The input reception unit 12 of the terminal device 10 accepts the login operation. Any existing login method is acceptable. Here, we assume that the login was successful. Upon successful login, a session is established between the terminal device 10 and the captured image management server 20. Processing between the terminal device 10 and the captured image management server 20 is performed while the session is established.

[0143] Users log in to the captured image management server 20 and then to the three-dimensional image management server 40, but they may also log in to the three-dimensional image management server 40 first and then to the captured image management server 20.

[0144] S2: Upon successful login, the transmitting / receiving unit 11 of the terminal device 10 sends a request for the property selection screen 200 to the captured image management server 20.

[0145] S3: The transmitting / receiving unit 21 of the captured image management server 20 receives a request for the property selection screen 200. The screen generation unit 22 generates the property selection screen 200, and the transmitting / receiving unit 21 transmits the screen information of the property selection screen 200 to the terminal device 10.

[0146] S4: The transmitting / receiving unit 11 of the terminal device 10 receives screen information from the property selection screen 200. The display control unit 13 displays the property selection screen 200 (see Figure 10). The user enters property identification information (e.g., V0001) on the displayed property selection screen 200. The input receiving unit 12 of the terminal device 10 receives the property identification information.

[0147] S5: The transmitting / receiving unit 11 of the terminal device 10 sends a request for property management information and live images to the captured image management server 20, specifying the property identification information.

[0148] S6: The transmitting / receiving unit 21 of the captured image management server 20 receives requests for property management information and live images, and the storage / reading unit 29 searches the captured image information management DB 2001 using the property identification information. Property management information is information about the property associated with the property identification information. The screen generation unit 22 of the captured image management server 20 generates a property management screen 210 that displays the property management information and live images, and the transmitting / receiving unit 21 transmits the screen information of the property management screen 210 to the terminal device 10.

[0149] Furthermore, the transmitting / receiving unit 21 sends an image request program to the terminal device 10 in response to a request for property management information, so that the terminal device 10 can acquire three-dimensional image information. The image request program is, for example, a web application. This web application is installed on the image capture management server 20 by the operator of the three-dimensional image management server 40 with the permission of the operator of the image capture management server 20. Alternatively, a URL containing the image request program may be sent to the terminal device 10. Since the web application acquires three-dimensional image information from the three-dimensional image management server 40, it has the function of connecting to the three-dimensional image management server 40 and requesting and displaying three-dimensional image information.

[0150] S7: The transmitting / receiving unit 11 of the terminal device 10 receives screen information and an image request program from the property management screen 210. The display control unit 13 displays the property management screen 210 (see Figure 11). This displays the property management information. The user requests three-dimensional image information of the property (by pressing the image acquisition button 213) based on the displayed property management information. The input receiving unit 12 of the terminal device 10 receives the request for three-dimensional image information of the property. Three-dimensional image information of the property is three-dimensional image information of items placed in the property, which has been generated as a virtual space. The items are composed of 3D model shape information. Since the property has already been identified, the request for three-dimensional image information of the property may be sent to the three-dimensional image management server 40 without any operation by the user.

[0151] Here, the property management screen 210 includes a first display area 214 that displays information about the item acquired from the captured image management server 20, and a second display area 215 that displays three-dimensional image information of the item acquired from the three-dimensional image management server 40. At step S7, the property management information is displayed in the first display area 214, but nothing is displayed in the second display area 215.

[0152] S8: If the user is not logged in to the 3D image management server 40, the user enters a login operation into the terminal device 10. This login operation is directed to the 3D image management server 40. The input reception unit 12 of the terminal device 10 accepts the login operation. Any existing login method is acceptable. Here, we assume that the login was successful. The 3D image management server 40 may also omit the user's login operation by using, for example, single sign-on. Upon successful login, a session is established between the terminal device 10 and the 3D image management server 40. Processing between the terminal device 10 and the 3D image management server 40 is performed while the session is established.

[0153] S9: The terminal device 10 executes an image request program to request three-dimensional image information. The transmitting / receiving unit 11 then sends a request for three-dimensional image information of the object selected by the user to the three-dimensional image management server 40, specifying the object identification information of the object. The transmitting / receiving unit 11 may also send the URL of the image capture management server 20 to the three-dimensional image management server 40 so that the terminal device 10 can be redirected to the image capture management server 20. Three-dimensional image information of an object is an image of an object placed in a virtual space. Since the object is composed of 3D model shape information, the terminal device 10 projects the 3D model shape of the object onto two dimensions to generate a planar image. The user can view any object while changing their viewpoint. The transmitting / receiving unit 11 may also have the image capture management server 20 send object management information obtained from it to the three-dimensional image management server 40. The image request program receives object management information from a web application connected to the image capture management server 20, for example, as a URL parameter.

[0154] S10: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives requests for three-dimensional image information of an object along with object identification information. The storage / reading unit 49 searches the three-dimensional image information management DB 4001 using the object identification information and obtains three-dimensional image information for each item. The processing unit 47 requests the screen generation unit 42 to generate a screen containing the three-dimensional image information of the object. The screen generation unit 42 generates a screen corresponding to the second display area 215 in which the three-dimensional image information of each item is arranged. The transmitting / receiving unit 41 transmits the screen information of the screen corresponding to the second display area 215 to the terminal device 10. The three-dimensional image information of each item included in the screen information is three-dimensional image information in which all items included in the object are placed in the object, and the user can arbitrarily change the viewpoint.

[0155] S11: The transmitting / receiving unit 11 of the terminal device 10 receives screen information for the screen corresponding to the second display area 215, and the display control unit 13 displays the property display screen 220 including the first display area 214 and the second display area 215 (see Figure 12). Three-dimensional image information of each item is displayed in the second display area 215, and the first display area 214 displays, for example, a list of items placed in the property (generated from property management information) and a live image. Thus, the item list, the live image, and the three-dimensional image information of the property are displayed on one screen. Next, the user specifies two points on the three-dimensional image information of the property using a mouse cursor 212 or the like to measure dimensions. The input receiving unit 12 of the terminal device 10 receives the coordinates of the two points on the item.

[0156] S12: When the user presses the measurement button 229, the transmitting / receiving unit 11 of the terminal device 10 sends a measurement request to the three-dimensional image management server 40, specifying the coordinates of two points.

[0157] S13: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives a measurement request. The measurement unit 51 searches the three-dimensional image information management DB 4001 based on the coordinates and identifies the item (model ID). The measurement unit 51 also searches the model shape management DB 4002 using the model ID and obtains the three-dimensional model shape information of the item. The measurement unit 51 measures the dimension between the coordinates of two points based on the three-dimensional model shape information.

[0158] S14: The transmitting / receiving unit 41 of the three-dimensional image management server 40 transmits the measurement result (dimension between the coordinates of two points) to the terminal device 10.

[0159] S15: The transmitting / receiving unit 11 of the terminal device 10 receives the measurement results, and the display control unit 13 displays the measurement results along with the three-dimensional image information of the property (see Figure 13).

[0160] <<Screen example>> Figure 10 shows an example of a property selection screen 200 for entering property identification information. The property selection screen 200 has a property identification information input field 201 and a search button 202. When the user enters the property identification information in the property identification information input field 201 and presses the search button 202, the list of room numbers shown in Figure 11 is displayed on the property management screen 210.

[0161] Figure 11 shows an example of a property management screen 210. The property management screen 210 includes a first display area 214 that displays information about items acquired from the captured image management server 20, and a second display area 215 that displays three-dimensional image information of items acquired from the three-dimensional image management server 40. The first display area 214 is the area other than the second display area 215. The first display area 214 includes a list 211 of room numbers and a live image 251 of the property identified by the property identification information. The live image 251 is a real-time video. The list of room numbers 211 corresponds to property management information, and each property has items, etc. The items in this room are the ceiling, floor, walls, and door. Depending on the property, the room number may not be displayed, and the user may transition from the property selection screen 200 in Figure 10 to Figure 12 to display the three-dimensional image information of the property. The user selects the room number for which they want to display the three-dimensional image information using the mouse cursor 212. When the user presses the image acquisition button 213, the property display screen 220 is displayed.

[0162] Figure 12 shows the property display screen 220, which includes property management information and three-dimensional image information 227. The first display area 214 is the same as in Figure 11. The second display area 215 of the property display screen 220 displays the three-dimensional image information 227 of these items. The user specifies two points to be measured using the mouse cursor 212. In Figure 12, two points on the wall are specified. When the user presses the measurement button 229, the three-dimensional image management server 40 starts measuring the distance between the two points.

[0163] Furthermore, the property display screen 220 displays the area (floor area) 224 as information about the property. The area (floor area) 224 may be a measured value or may be included in the property management information.

[0164] Note that the screen shown in Figure 12, which displays property management information (a list of room numbers 211 and item names), live images 251, and three-dimensional image information of the property 227, is an example of the first display screen.

[0165] Figure 13 shows the property display screen 220 with the measurement results displayed. As can be seen by comparing it with Figure 12, the measurement result shows the dimension 228 between the two points.

[0166] In this way, when a user logs in to the 3D image management server 40 via the captured image management server 20, the terminal device 10 can display property management information and 3D image information of the property on a single screen. The user can then perform tasks using the 3D image information of the property, such as measuring the distance 228 between two points, while viewing the property management information.

[0167] <<Direct login to the image management server>> Next, we will explain the case where a user logs directly into the 3D image management server 40 and measures the distance between two points.

[0168] Figure 14 is a sequence diagram showing an example of a measurement process in which a user requests the three-dimensional image management server 40 to measure the distance between two points on an object or property.

[0169] S101: The user enters a login operation into terminal device 10. This login is for the three-dimensional image management server 40. The input reception unit 12 of terminal device 10 accepts the login operation. Any existing login method is acceptable. Here, we assume that the login was successful.

[0170] S102: Upon successful login, the transmitting / receiving unit 11 of the terminal device 10 sends a request for the property selection screen 200 to the three-dimensional image management server 40.

[0171] S103: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives a request for the property selection screen 200. The screen generation unit 42 generates the property selection screen 200, and the transmitting / receiving unit 41 transmits the screen information of the property selection screen 200 to the terminal device 10.

[0172] S104: The transmitting / receiving unit 11 of the terminal device 10 receives screen information from the property selection screen 200. The display control unit 13 displays the property selection screen 200 (see Figure 10). The user enters property identification information (e.g., V0001) on the displayed property selection screen 200. The input receiving unit 12 of the terminal device 10 receives the property identification information.

[0173] S105: The transmitting / receiving unit 11 of the terminal device 10 sends a request for three-dimensional image information of the property to the three-dimensional image management server 40, specifying the property identification information. Note that since the terminal device 10 is not logged into the captured image management server 20, the property management screen 210 shown in Figure 11 is not displayed.

[0174] S106: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives a request, and the storage / reading unit 49 searches the three-dimensional image information management DB 4001 using the object identification information. The storage / reading unit 49 obtains the three-dimensional image information of each item. The screen generation unit 42 generates an object display screen 320 in which the three-dimensional image information of each item is arranged. The transmitting / receiving unit 41 transmits the three-dimensional image information of the object display screen 320 to the terminal device 10. The three-dimensional image information of each item is three-dimensional image information in which all items included in the object are placed in the object, and the user can arbitrarily change the viewpoint.

[0175] S107: The transmitting / receiving unit 11 of the terminal device 10 receives the three-dimensional image information to be displayed on the property display screen 320, and the display control unit 13 displays the property display screen 320 (see Figure 15). In the process shown in Figure 14, the terminal device 10 is not logged into the captured image management server 20, so the property display screen 320 does not display the item list 221 (property management information) and the live image 251 placed on the property. However, the screen generation unit 42 may use the three-dimensional image information management DB 4001 managed by the three-dimensional image management server 40 to display information equivalent to the item list. Next, the user specifies two points on the three-dimensional image information of the property using a mouse cursor or the like to measure dimensions. The input receiving unit 12 of the terminal device 10 receives the coordinates of the two points on the property.

[0176] S108: When the user presses the measurement button 229, the transmitting / receiving unit 11 of the terminal device 10 sends a measurement request to the three-dimensional image management server 40, specifying the coordinates of two points.

[0177] S109: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives a measurement request. The measurement unit 51 searches the three-dimensional image information management DB 4001 based on the coordinates and identifies the item (model ID). The measurement unit 51 also searches the model shape management DB 4002 using the model ID and obtains the three-dimensional model shape information of the item. The measurement unit 51 measures the dimension between the coordinates of two points based on the three-dimensional model shape information.

[0178] S110: The transmitting / receiving unit 41 of the three-dimensional image management server 40 transmits the measurement result (distance between two points) to the terminal device 10.

[0179] S111: The transmitting / receiving unit 11 of the terminal device 10 receives the measurement result, and the display control unit 13 displays the measurement result on the property display screen 320 (see Figure 16).

[0180] <<Screen example>> The property selection screen 200 can be the same as in Figure 10. Also, if the user logs in directly to the 3D image management server 40, the property management screen 210 in Figure 11 will not be displayed.

[0181] Figure 15 shows the property display screen 320, which includes three-dimensional image information of the property. Compared to Figure 12, the item list 221 and live image 251 are not displayed. This is because the item list 221 and live image 251 are managed by the captured image management server 20. The method for the user to specify the coordinates of two points is the same as in Figure 12.

[0182] Note that the screen shown in Figure 15, which displays the property's three-dimensional image information 227 without displaying property management information, is an example of a second display screen.

[0183] Figure 16 shows the property display screen 320 with the measurement results displayed. Compared to Figure 13, the item list 221 and live image 251 are not displayed. This is because the item list 221 and live image 251 are managed by the captured image management server 20. Note that the measurement result, the dimension 228 between the two points, is the same as in Figure 13.

[0184] In this way, when a user logs in directly to the three-dimensional image management server 40, the terminal device 10 displays the three-dimensional image information 227 of the property. Therefore, if a user does not have the authority to use the captured image management server 20, the three-dimensional image management server 40 can be restricted from providing the user with the information managed by the captured image management server 20.

[0185] <Main effects> According to this embodiment, the three-dimensional image management server 40 processes information in response to a user logging into the first server and processes information in response to a user logging into the second server. In other words, the information displayed on the terminal device 10's screen can be changed depending on whether the user logs into the three-dimensional image management server 40 directly or via the captured image management server 20. If the user does not have the authority to use the captured image management server 20, the three-dimensional image management server 40 can be restricted from providing information managed by the captured image management server 20. Furthermore, the three-dimensional image management server 40 can provide the same measurement results whether the user logs into the three-dimensional image management server 40 directly or via the captured image management server 20.

[0186] [Second Embodiment] In this embodiment, we will describe an information processing system 100 that uses a first tacit knowledge model 4004A and a second tacit knowledge model 4004B depending on whether the user logged in to the three-dimensional image management server 40 via the captured image management server 20 or logged in to the three-dimensional image management server 40 directly.

[0187] In this embodiment, the hardware configuration diagram shown in Figure 2 and the functional block diagram shown in Figure 3, as described in the above embodiment, can be used as references.

[0188] <Action or process> <<Login to the 3D image management server via the captured image management server>> First, we will explain the case where a user logs in to the three-dimensional image management server 40 via the captured image management server 20. We will also explain the model update process in which the first tacit knowledge model 4004A learns from the data.

[0189] ●Learning Phase (Model Update) Figure 17 is a sequence diagram showing an example of the model update process. The processing in steps S21 to S30 can be the same as in Figure 9. In step S27, the user can arbitrarily change the viewpoint of the live image. The terminal device 10 also obtains the current shooting position information of the shooting device 10 from the captured image management server 20. The field of view information and shooting position information are sent to the three-dimensional image management server 40. The screen generation unit 42 generates three-dimensional image information by placing a virtual camera at the position of the shooting position information and determining the field of view of the virtual camera based on the field of view information. As a result, in the initial state in step S31, three-dimensional image information 222 with the same shooting position and field of view as the live image 251 is displayed.

[0190] S31: The transmitting / receiving unit 11 of the terminal device 10 receives screen information for the screen corresponding to the second display area 215, and the display control unit 13 displays the property display screen 330 including the first display area 214 and the second display area 215 (see Figure 19). For example, a list of items placed in the property, a live image 251, and three-dimensional image information of the property are displayed on one screen.

[0191] Next, the user identifies an arbitrary item from the three-dimensional image information of the property (for example, by pressing it). The input reception unit 12 of the terminal device 10 accepts the operation to identify the item. The user can enlarge the arbitrary item or change the viewpoint. The user can also specify the field of view information. The terminal device 10 also obtains the current shooting position information of the shooting device 5 from the captured image management server 20. If the terminal device 10 is fixed, the shooting position information only needs to be obtained once. Once the user identifies an item, they can request a captured image of the item and the audio text associated with the captured image. The item may be identified, for example, by the coordinates clicked by the user, or the model ID may be identified by these coordinates.

[0192] Furthermore, users input comments (text information, audio) about the items into the terminal device 10, as explained in Figures 7 and 8. These comments are sometimes referred to as input information. These comments may constitute tacit knowledge comments. Additionally, the comments may include caption comments describing the items.

[0193] S32: When the user presses the information update button 226, the transmitting / receiving unit 11 of the terminal device 10 transmits information identifying the item (e.g., model ID), shooting location information, field of view information, and input information to the three-dimensional image management server 40.

[0194] S33: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives information that the information update button 226 has been pressed, information identifying the item (e.g., model ID), shooting location information, field of view information, and input information. The storage / reading unit 49 identifies the model ID of the item with the closest location information from the three-dimensional image information management DB 4001 based on the information identifying the item (in this case, location information). Note that if the information identifying the item in step S32 is the model ID, searching the three-dimensional image information management DB 4001 is unnecessary. The transmitting / receiving unit 41 transmits the shooting location information and field of view information to the terminal device 10. The three-dimensional image management server 40 transmits the shooting location information and field of view information in order to request the captured image management server 20 to provide a captured image and audio text taken from the same location and with the same field of view.

[0195] The decision unit 48 then decides whether to update the first tacit knowledge model 4004A or the second tacit knowledge model 4004B. Here, the three-dimensional image management server 40 received a login from the image request program used when logging into the captured image management server 20 in step S28, so the decision unit 48 determines that the login was via the captured image management server 20. Therefore, the decision unit 48 decides to update the first tacit knowledge model 4004A. The process by which the decision unit 48 determines which model to update is explained in Figure 18.

[0196] S34: The transmitting / receiving unit 11 of the terminal device 10 receives a request for a captured image and audio text (shooting location information and field of view information). For example, the 3D image management server 40 notifies the terminal device 10 of the URL of the captured image management server 20 and redirects it. As a result, the transmitting / receiving unit 11 of the terminal device 10 specifies the shooting location information and field of view information and sends a request for a captured image and audio text to the captured image management server 20.

[0197] S35: The transmitting / receiving unit 21 of the captured image management server 20 receives a request for a captured image and audio text. The storage / reading unit 29 retrieves from the captured image information management DB 2001 a captured image that has the same location information as the shooting location information and is captured with the closest field of view information to the received field of view information, as well as the audio text associated with this captured image. It is expected that this captured image will show the same object as the three-dimensional image information. The transmitting / receiving unit 21 transmits the captured image and audio text to the terminal device 10. The captured image management server 20 may also capture from the latest live image using the shooting location information and field of view information.

[0198] S36: When the transmitting / receiving unit 11 of the terminal device 10 receives the captured image and audio text, it transmits the captured image and audio text to the three-dimensional image management server 40. The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives the captured image and audio text as a response to the request in step S33. Upon receiving the captured image and audio text, the storage / reading unit 49 associates the captured image with the model ID identified in step S29 and saves it to the three-dimensional image information management DB 4001. The storage / reading unit 49 may also save the audio text.

[0199] S37: Next, the determination unit 43 obtains a caption comment identified by the model ID from the caption model 4003 and determines the degree of relevance between the caption comment and the comments included in the input information received in step S32. The determination unit 43 may determine the degree of relevance between the obtained caption comment and all the comments included in the input information received in step S32, or it may divide the comments included in the input information received in step S32 into multiple parts and determine the degree of relevance between the obtained caption comment and each divided comment.

[0200] S38: The update unit 46 updates the caption model 4003 by associating the comments deemed highly relevant in step S37 with the model ID as caption comments. The update unit 46 also updates the first tacit knowledge model 4004A determined by the decision unit 48. The update unit 46 updates the first tacit knowledge model 4004A using the comments and audio text deemed less relevant in step S37, along with the three-dimensional image information of the related item (identified in step S32) and captured image, as training data. In other words, the correspondence between the three-dimensional image information and captured image of the item and the comments and audio text is learned. Features are extracted from the three-dimensional image information and captured image of the item using several feature extraction models suitable for images, such as CNNs. Features represent, for example, what is pictured where, or the content of the work being performed. Therefore, the first tacit knowledge model 4004A can learn the correspondence between the features of the three-dimensional image information and captured image of the item and the comments and audio text.

[0201] Note that both comments and audio text are not necessarily required; the first tacit knowledge model 4004A can be updated with at least one of either comments or audio text.

[0202] Figure 18 is a flowchart illustrating how the decision unit 48 determines whether to update the first tacit knowledge model 4004A or the second tacit knowledge model 4004B. In Figure 18, the decision unit 48 determines whether it has logged into the three-dimensional image management server 40 via the captured image management server 20 (S111). The decision unit 48 can determine whether it has logged into the three-dimensional image management server 40 via the captured image management server 20 by whether the login was made using an image request program distributed from the captured image management server 20.

[0203] If the decision in step S111 is Yes, the decision unit 48 decides to update the first tacit knowledge model 4004A (S112).

[0204] If the decision in step S111 is No, the decision unit 48 decides to update the second tacit knowledge model 4004B (S113).

[0205] Although Figure 18 illustrates the process of updating a model, it can also be applied to selecting a model used to generate text information.

[0206] <<Screen example>> The property selection screen 200 in the learning phase can be the same as in Figure 10, and the property management screen 210 can be the same as in Figure 11. On the other hand, the property display screen 220 in Figure 12 will be as shown in Figure 19.

[0207] Figure 19 shows a property display screen 330 that includes property management information and three-dimensional image information. The property display screen 330 includes a first display area 214 and a second display area 215. The first display area 214 of the property display screen 330 displays an item list 216, a live image 251, and area (floor area) 224.

[0208] The items in this room are the ceiling, floor, walls, and door. In the second display area 215 of the property display screen 330, three-dimensional image information 222 of these items, such as a table, is displayed. In the initial state, three-dimensional image information 222 is displayed with the same shooting position and field of view as the live image 251. This shooting position and field of view can be specified by the user for the live image 251, or they can remain in their initial state.

[0209] The user changes the viewpoint and field of view of the three-dimensional image information 222, and for example, by clicking on the three-dimensional image information 223 of a table, inputs input information 241 that can become an implicit knowledge comment. The second display area 215 displays the input information 241, corresponding to the three-dimensional image information 223 of the table, which reads, "This table has an unstable center of gravity, so it is best not to place anything weighing more than 50 kg on it." The three-dimensional image management server 40 can update the first implicit knowledge model 4004A using such input information 241 and voice text. In addition, the area (floor area) 224 can become a caption comment as information about the property.

[0210] When the user presses the information update button 226, the first tacit knowledge model 4004A is updated. When the information display button 225 is pressed, text information is generated based on the tacit knowledge comments generated by the first tacit knowledge model 4004A.

[0211] ● Inference Phase (Text Information Generation) Next, we will describe the text information generation process using the first tacit knowledge model 4004A.

[0212] Figure 20 is a sequence diagram showing an example of the text information generation process. The explanation of Figure 20 mainly focuses on the differences from Figure 17. The processes in steps S41 to S56 can be the same as in Figure 17. However, in step S51, the user enters a question and presses the information display button 225 (see Figure 21).

[0213] S57: The decision unit 48 decides whether to use the first tacit knowledge model 4004A or the second tacit knowledge model 4004B to generate text information. Here, the three-dimensional image management server 40 received a login from the image request program used when logging into the captured image management server 20 in step S48, so the decision unit 48 determines that the login was via the captured image management server 20. Therefore, the decision unit 48 decides to generate text information using the first tacit knowledge model 4004A.

[0214] When the transmitting / receiving unit 41 of the three-dimensional image management server 40 receives a captured image and audio text, the storage / reading unit 49 identifies the item using the model ID and saves the captured image in the three-dimensional image information management DB 4001, associating it with the model ID. The storage / reading unit 49 may also save the audio text, associating it with the model ID.

[0215] The processing unit 47 requests the text information generation unit 45 to generate text information. The text information generation unit 45 obtains tacit knowledge comments corresponding to the three-dimensional image information and captured image of the item from the first tacit knowledge model 4004A. The first tacit knowledge model 4004A can extract features of the three-dimensional image information and captured image of the item and identify at least one of the comments or audio text corresponding to these features as tacit knowledge comments. The three-dimensional image information of the item is the three-dimensional image information of the item identified by the user in step S51. The user may specify the three-dimensional image information of multiple items or all items.

[0216] S58: Next, the text information generation unit 45 obtains text information created by the large-scale language model 4005 using the tacit knowledge comments, input information (question text), and speech text. The large-scale language model 4005 can use these to generate more detailed text information. The text information generation unit 45 may also convert the speech information included in the input information into text information, and the text information generated by the text information generation unit 45 may be either speech information or text information.

[0217] The text information generation unit 45 may generate text information without using any speech text or question text. Alternatively, the text information generation unit 45 may generate fixed questions internally within the system and use these fixed questions. In this case, the question text is not visible to the user. Or, the text information generation unit 45 may generate fixed questions internally within the system, display these fixed questions on the display unit for the user to select, and then use the selected question.

[0218] While speech-to-text is not strictly required, using speech-to-text to generate text information from the large-scale language model 4005 allows for more detailed information about an item. For example, if the speech-to-text includes the extent of damage to the item, it is possible to generate text information that includes appropriate responses based on the extent of the damage.

[0219] S59: The processing unit 47 associates the three-dimensional image information of the item corresponding to the model ID with the captured image and text information, and requests the screen generation unit 42 to display them. The screen generation unit 42 generates a screen corresponding to the second display area 215, which displays the three-dimensional image information, the captured image, and the text information in association. The screen generation unit 42 may also perform an update process to add only the text information to the screen corresponding to the second display area 215. The transmitting / receiving unit 41 of the three-dimensional image management server 40 transmits screen information of the screen corresponding to the second display area 215 to the terminal device 10, and the transmitting / receiving unit 11 of the terminal device 10 receives screen information of the screen corresponding to the second display area 215 transmitted from the three-dimensional image management server 40.

[0220] S60: The display control unit 13 of the terminal device 10 displays a text image screen 230 including a first display area 214 and a second display area 215 (see Figure 22). Alternatively, the conversion unit 15 converts the received text information into audio information, and the audio control unit 14 plays the converted text information through the speaker 109a. If the received text information is audio information, the text information is played through the speaker 109a, or the conversion unit 15 converts the received text information into character information and displays the converted text information on the display 106a.

[0221] <<Example of the inference phase screen>> Of the screens displayed by the terminal device 10 during the inference phase, the property selection screen 200 may be the same as in Figure 10, and the property management screen 210 may be the same as in Figure 11. On the other hand, the property display screen 220 in Figure 12 will be as shown in Figure 21.

[0222] Figure 21 shows an example of the property display screen 340 during the inference phase. The property display screen 240 includes a first display area 214 and a second display area 215. Figure 21 has the same configuration as Figure 19, but the user presses the three-dimensional image information 223 of the table and inputs a question 234 as input information. The second display area 215 displays the input information (question 234) corresponding to the three-dimensional image information 223 of the table. For example, the question 234 in Figure 21 is "There is a scratch on the table, what should I do?" Along with such a question 234, the user presses the information display button 225 to request the generation of text information using the tacit knowledge model. As a result, the text information generation unit 45 generates text information using the first tacit knowledge model 4004A and the large-scale language model 4005.

[0223] Note that the screen shown in Figure 21, which displays property management information (a list of room numbers and item names) and three-dimensional image information of the property 222, is an example of the first display screen.

[0224] Figure 22 shows an example of a text image screen 230 containing text information. The text image screen 230 includes a first display area 214 and a second display area 215. In Figure 22, the user is displaying a large image of a table, specifically the three-dimensional image information 223. The text image screen 230 also contains text information 235. The text information 235 is displayed in association with the captured image 252 in the second display area 215. The text information 235 reads, "If the scratch is less than 1 mm deep, it will be repaired with paint. If it is 1 mm or deeper, it will be polished." The text information 235 was generated by the large-scale language model 4005 from tacit knowledge comments, voice text, and question sentences. For example, if a scratch is detected in the captured image 252 of an item, a tacit knowledge comment regarding the scratch on this item is extracted. This tacit knowledge comment, a question sentence about the scratch, and voice text identifying the current state of the scratch are input to the large-scale language model 4005, allowing it to generate appropriate text information in response to a question about the current scratch.

[0225] <Effects of generating text information using captured images> This invention will explain the effects of generating text information using captured images.

[0226] 1. Comparative Example 1 (Using a General Large-Scale Language Model) Question: "How should I repair the cracks?" Tacit comment: Tape or filler can be used.

[0227] 2. Comparative Example 2 (Case of learning from three-dimensional image information) • Learning Phase Input image: Three-dimensional image information Comment: Use tape for wide cracks and filler for narrow cracks. • Inference Phase Input image: 3D image display only Implicit knowledge comment: There are wide cracks and narrow cracks, so we recommend using tape for the former and filler for the latter.

[0228] 3. This embodiment (three-dimensional image information, captured image, audio text) • Learning Phase Input images: Three-dimensional image information and captured images Audio text: Applying tape to the corners may cause cracking. • Inference Phase Input images: Three-dimensional image information and captured images Question: "How should I repair the cracks?" Implicit knowledge comment: There are wide cracks and narrow cracks, so we recommend using tape for the former and filler for the latter, but be careful when applying tape to corners as it may cause cracks to form. In other words, "Be careful when applying tape to corners as it may cause cracks to form" is the effect of learning from the captured image and audio text.

[0229] 4. This embodiment (three-dimensional image information, captured image, audio text, input information) • Learning Phase Input images: Three-dimensional image information and captured images Audio text: Applying tape to the corners may cause cracking. Input information: Use tape for wide cracks and filler for narrow cracks. • Inference Phase Input images: 3D image display and captured images Question: "How should I repair the cracks?" Implicit knowledge comment: There are wide cracks and narrow cracks, so we recommend using tape for the former and filler for the latter, but please be careful when applying tape to corners as cracks may occur. In other words, "Please be careful when applying tape to corners as cracks may occur" is the effect of learning from the captured image and audio text.

[0230] <<Direct login to the 3D image management server>> Next, we will explain the case where a user logs in directly to the three-dimensional image management server 40. We will also explain the model update process in which the second tacit knowledge model 4004B learns from the data. ●Learning Phase (Model Update) Figure 23 is a sequence diagram showing an example of the model update process. The process in steps S121 to S126 can be the same as in Figure 14.

[0231] S127: The transmitting / receiving unit 11 of the terminal device 10 receives the three-dimensional image information of the property display screen 350, and the display control unit 13 displays the property display screen 350 (see Figure 24). In this embodiment, since the terminal device 10 is not logged into the captured image management server 20, the item list 216 and live image 251 placed on the property are not displayed. However, the screen generation unit 42 may use the three-dimensional image information management DB 4001 managed by the three-dimensional image management server 40 to display information equivalent to the item list 216. Next, the user identifies an arbitrary item from the three-dimensional image information of the property. The input reception unit 12 of the terminal device 10 accepts the operation to identify an item. The item may be identified, for example, by the coordinates clicked by the user, or the model ID may be identified by these coordinates.

[0232] The user inputs comments (text information, audio) about the item into the terminal device 10, as explained in Figures 7 and 8. These comments are sometimes referred to as input information. These comments may constitute tacit knowledge comments. Furthermore, the comments may include caption comments describing the item.

[0233] S128: When the user presses the information update button 226, the transmitting / receiving unit 11 of the terminal device 10 transmits to the three-dimensional image management server 40 that the information update button 226 has been pressed, along with information identifying the item and the input information. The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives these. The decision unit 48 decides whether to update the first tacit knowledge model 4004A or the second tacit knowledge model 4004B. The decision unit 48 determines that the login in step S121 was not a login using the image request program distributed from the captured image management server 20 (i.e., a direct login to the three-dimensional image management server 40), and therefore decides to update the second tacit knowledge model 4004B.

[0234] S129: The determination unit 43 obtains a caption comment identified by a model ID from the caption model 4003 and determines the degree of association between the caption comment and the comments included in the input information received in step S128. The determination unit 43 may determine the degree of association between the obtained caption comment and all the comments included in the input information received in step S128, or it may divide the comments included in the input information received in step S128 into multiple parts and determine the degree of association between the obtained caption comment and each divided comment.

[0235] S130: The update unit 46 updates the caption model 4003 by associating the comments included in the input information, which were determined to be highly relevant in step S129, with the model ID as caption comments. The update unit 46 also updates the second tacit knowledge model 4004B using the comments included in the input information, which were determined to be less relevant in step S129, and the three-dimensional image information of the related item (identified in step S128) as training data. In other words, the correspondence between the three-dimensional image information of the item and the comments is learned. Features are extracted from the three-dimensional image information of the item using several feature extraction models suitable for images, such as CNNs. Features represent, for example, what is pictured where, or the content of the work being performed. Therefore, the second tacit knowledge model 4004B can learn the correspondence between the features of the three-dimensional image information of the item and the comments.

[0236] <<Screen example>> The property selection screen 200 displayed by the terminal device 10 during the learning phase may be the same as in Figure 10. Figure 11 is not displayed because it is a screen generated by the captured image management server 20. The property display screen 350 of this embodiment will be described based on Figure 24.

[0237] Figure 24 shows the property display screen 350 of this embodiment. Comparing Figure 24 with Figure 19, the item list 216 and live image 251 are not displayed. This is because the terminal device 10 has logged directly into the three-dimensional image management server 40. The user enters input information 241 that may become tacit knowledge comments and presses the information update button 226. This starts the update of the second tacit knowledge model 4004B in the three-dimensional image management server 40.

[0238] Users can change the viewpoint and field of view of the three-dimensional image information 222. While captured images and audio text are not acquired based on the viewpoint and field of view, the three-dimensional image information 222 identified by the viewpoint and field of view can be used for training.

[0239] Note that the screen shown in Figure 24, where property management information (such as the property's room number and item name) and the live image 251 are not displayed but the property's three-dimensional image information 222 is displayed, is an example of a second display screen.

[0240] ● Inference Phase (Text Information Generation) Next, we will describe the text information generation process using the second tacit knowledge model 4004B.

[0241] Figure 25 is a sequence diagram showing an example of the text information generation process. The explanation of Figure 25 mainly focuses on the differences from Figure 23. The processes in steps S141 to S148 are the same as in Figure 23. However, in step S147, the user enters a question and presses the information display button 225 (see Figure 26).

[0242] S149: When the user presses the information display button 225, the transmitting / receiving unit 11 of the terminal device 10 transmits to the three-dimensional image management server 40 that the information display button 225 has been pressed, information identifying the item, and input information. The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives these. The decision unit 48 decides whether to use the first tacit knowledge model 4004A or the second tacit knowledge model 4004B to generate the text information. The decision unit 48 determines that the login in step S141 is not a login using an image request program distributed from the captured image management server 20 (i.e., a direct login to the three-dimensional image management server 40), and therefore decides to use the second tacit knowledge model 4004B.

[0243] The processing unit 47 requests the text information generation unit 45 to generate text information. The text information generation unit 45 obtains tacit knowledge comments corresponding to the three-dimensional image information of the item from the second tacit knowledge model 4004B. The second tacit knowledge model 4004B can extract features of the three-dimensional image information of the item and identify input information (comments) corresponding to these features as tacit knowledge comments.

[0244] S150: Next, the text information generation unit 45 obtains text information created by the large-scale language model 4005 using the tacit knowledge comments and input information (question text). The large-scale language model 4005 can use these to generate more detailed text information. The text information generation unit 45 may also convert the audio information contained in the input information into text information, and the text information generated by the text information generation unit 45 may be either audio information or text information.

[0245] The text information generation unit 45 may generate text information without using any question text. Alternatively, the text information generation unit 45 may generate fixed questions internally within the system and use those fixed questions. In this case, the question text is not visible to the user. Or, the text information generation unit 45 may generate fixed questions internally within the system, display the fixed questions on the display unit for the user to select, and use the selected question.

[0246] S151: The transmission / reception unit 41 of the three-dimensional image management server 40 transmits the generated text information to the terminal device 10 together with the screen information of the text image screen 370. The transmission / reception unit 11 of the terminal device 10 receives the screen information and text information of the text image screen 370 transmitted from the three-dimensional image management server 40.

[0247] S152: The display control unit 13 of the terminal device 10 displays the text image screen 370 including the text information (see FIG. 27). Alternatively, the conversion unit 15 converts the received text information into voice information, and the voice control unit 14 reproduces the converted text information on the speaker 109a. Also, when the received text information is voice information, the text information is reproduced on the speaker 109a, or the conversion unit 15 converts the received text information into character information and displays the converted text information on the display 106a.

[0248] <<Screen example in the inference phase>> Among the screens displayed by the terminal device 10 in the inference phase, the property designation screen 200 may be the same as in FIG. 10, and the property management screen 210 in FIG. 11 is not displayed. On the other hand, the property display screen 220 in FIG. 12 becomes as shown in FIG. 26.

[0249] FIG. 26 shows an example of the property display screen 360 in the inference phase. FIG. 26 has the same configuration as FIG. 21, but the item list 216 and the live image 251 are not displayed. This is because the terminal device 10 is not logged in to the captured image management server 20. The user inputs the question sentence 234 and presses the information display button 225 to request the generation of text information using the tacit knowledge model. Thereby, the text information generation unit 45 generates text information using the second tacit knowledge model 4004B and the large language model 4005.

[0250] Note that the user can change the viewpoint and angle of view of the three-dimensional image information 222. Although the captured image and voice text are not acquired based on the viewpoint and angle of view, the three-dimensional image information 222 specified by the viewpoint and angle of view can be used for the generation of text information.

[0251] In addition, a screen on which three-dimensional image information 222 of a property is displayed without displaying property management information (such as the room number of the property, the name of the item, etc.) as shown in FIG. 26 is an example of the second display screen.

[0252] FIG. 27 shows an example of a text image screen 370 including text information. The text image screen 370 has text information 236. This text information 236 is "Scratches will be dealt with by painting or polishing". The text information 236 is generated by the large language model 4005 from the tacit knowledge comment generated by the second tacit knowledge model 4004B and the input information (question text). Therefore, even if there are scratches on the actual item, if there is no description of the scratches in the question text, the tacit knowledge comment does not reflect the scratches. Also, the large language model 4005 does not use voice text for generating the text information.

[0253] Therefore, when comparing the text information 236 in FIG. 27 with the text information 235 in FIG. 22, the text information 236 is general text information regarding scratches on the table and is inferior to the text information 235 in terms of detail. However, the text information 236 is information with high versatility regarding scratches on the table.

[0254] <Example of the three-dimensional image management server acquiring a captured image and voice text from the captured image management server> In FIGS. 17 and 20, the three-dimensional image management server 40 acquired the captured image and voice text that the terminal device 10 obtained from the captured image management server 20. However, it is also possible for the three-dimensional image management server 40 to directly acquire the captured image and voice text from the captured image management server 20.

[0255] FIG. 28 is a sequence diagram showing an example of a process in which the three-dimensional image management server 40 communicates with the captured image management server 20 to update the model. Note that in FIG. 28, mainly the differences from FIG. 17 are explained, but the sequence diagram in FIG. 20 is similarly modified. First, the processes in steps S21 to S32 may be the same as those in FIG. 17.

[0256] S33: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives information that the information update button 226 has been pressed, information identifying the item (shooting location information, field of view information), and input information. The storage / reading unit 49 identifies the model ID of the item with the closest location information from the three-dimensional image information management DB 4001 based on the information identifying the item (in this case, the clicked location information). The processing unit 47 requests the transmitting / receiving unit 41 to acquire the captured image and audio text. The transmitting / receiving unit 41 sends the request for the captured image and audio text to the captured image management server 20 by calling the API of the captured image management server 20.

[0257] S36: The transmitting / receiving unit 21 of the captured image management server 20 receives a request for a captured image and audio text. The storage / reading unit 29 retrieves from the captured image information management DB 2001 a captured image that has the same location information as the shooting location information and is captured with the closest field of view information to the received field of view information, as well as the audio text associated with this captured image. It is expected that this captured image will show the same object as the three-dimensional image information. The transmitting / receiving unit 21 sends the captured image and audio text to the three-dimensional image management server 40.

[0258] The subsequent processing can be the same as in Figure 17. Also, in Figure 28, the process by which the 3D image management server 40 acquires captured images and audio text from the captured image management server 20 is explained using a sequence diagram during model update as an example, but the process is the same when generating text information as in Figure 20.

[0259] <Criteria for users to decide which login to use> From the user's perspective, the text information they receive differs depending on whether they log in to the 3D image management server 40 or the captured image management server 20. Therefore, we will explain the criteria for users to decide which server to log in to.

[0260] As described above, the first tacit knowledge model 4004A and the second tacit knowledge model 4004B have the following differences. • The first tacit knowledge model 4004A can generate expert knowledge and text information specific to particular items. • The second tacit knowledge model 4004B can generate expert knowledge and general text information applicable to similar (same-category) items in general.

[0261] For example, if a specific item is a turbo chiller used by a customer, then because it is an item owned by the customer, there is an accumulation of inspection history and know-how regarding that item. The user decides to use this information and the first tacit knowledge model 4004A to generate highly accurate text information (answers) specifically for that particular item.

[0262] On the other hand, while such highly accurate information does not exist for all similar items (refrigeration machines in the category of turbo chillers), specialized knowledge about turbo chillers in general does exist. Therefore, in this case, it is thought that the user would use the second tacit knowledge model 4004B to generate general text information (answers) applicable to all similar items. Thus, the user can decide whether to use captured images and audio-text to generate text information depending on the level of detail required.

[0263] Furthermore, instead of the user making the decision, the decision unit 48 may decide automatically (without confirming with the user) or semi-automatically (by recommending to the user and asking for confirmation) whether to use captured images and audio text to generate text information. For example, if the question sentence included in the input information (audio, text) concerns the inspection results of an item, the decision unit 48 may decide to use the first tacit knowledge model 4004A because the second tacit knowledge model 4004B may not be able to generate appropriate text information.

[0264] Furthermore, there may be three or more types of tacit knowledge models, not just two, and users may be able to select the tacit knowledge model they prefer.

[0265] <Multimodal> Describe some examples of combinations of input information and tacit knowledge comments. In the above-described model, it is assumed that it is a large language model. However, in this embodiment, a multimodal model that inputs a plurality of data formats (images, texts, gestures, etc.) and outputs in a predetermined data format can be used. · When the input information is a character string and content other than text information is generated as tacit knowledge comments Input a character string to generate an image Input a character string to generate a video Input a character string to generate audio Input a character string to generate a 3D model · When the input information includes a character string and something other than a character string, and text information is generated as tacit knowledge comments Input an image and a character string to generate text information Input a 3D model and a character string to generate text information Input audio and a character string to generate text information · When the input information includes a character string and something other than a character string, and content other than text information is generated as tacit knowledge comments Input an image and a character string to generate an image Input a video and a character string to generate a video Input a 3D model and a character string to generate a 3D model Input audio and a character string to generate audio <Main effects> According to this embodiment, the three-dimensional image management server 40 can selectively use the first tacit knowledge model 4004A learned with the captured image and voice text and the second tacit knowledge model 4004B learned without using the captured image and voice text. That is, for a user who logs in via the photographed image management server 20, the first tacit knowledge model 4004A can be used to generate detailed text information, and for a user who logs in directly to the three-dimensional image management server 40, the second tacit knowledge model 4004B can be used to generate highly versatile text information.

[0266] [Third Embodiment] In this embodiment, an information processing system 100 in which the three-dimensional image management server 40 performs a simulation will be described. Since the simulation is only possible on the three-dimensional image management server 40, this function is not provided when the terminal device 10 is connected to the captured image management server 20.

[0267] In this embodiment, the hardware configuration diagram shown in Figure 2 and the functional block diagram shown in Figure 3, as described in the above embodiment, can be used as references.

[0268] <Action or process> Figure 29 is a sequence diagram illustrating the process by which the three-dimensional image management server 40 executes the simulation. The processes in steps S201 to S210 can be the same as in Figure 9.

[0269] S211: The transmitting / receiving unit 11 of the terminal device 10 receives screen information from the property display screen 380, and the display control unit 13 displays the property display screen 380 (see Figure 30). The user presses the simulation execution button 243 to perform a simulation related to the property or item. The input reception unit 12 receives the press.

[0270] S212: Since the simulation is a function of the 3D image management server 40, the transmitting / receiving unit 11 logs out of the captured image management server 20. This is because the 3D image management server 40 will execute the simulation while the user is logged in only to the 3D image management server 40.

[0271] S213: Next, the user enters a login operation into the terminal device 10. The image request program should prompt the user to log in to the three-dimensional image management server 40. This login is for the three-dimensional image management server 40. The input reception unit 12 of the terminal device 10 accepts the login operation. Any existing login method is acceptable. Here, we assume that the login was successful. Since the user has already logged in to the three-dimensional image management server 40 in step S208, the login in step S213 may be omitted.

[0272] S214: Upon successful login, the transmitting / receiving unit 11 of the terminal device 10 sends a simulation execution request to the three-dimensional image management server 40. Since the user will later log in to the captured image management server 20, the transmitting / receiving unit 11 may send the URL of the captured image management server 20 to the three-dimensional image management server 40 for redirection.

[0273] S215: The transmission / reception unit 41 of the three-dimensional image management server 40 receives a simulation execution request. The simulation unit 52 executes the simulation. There are no particular restrictions on the content of the simulation, but the three-dimensional image management server 40 may execute any simulation it is capable of, or the user may specify one.

[0274] S216: The screen generation unit 42 of the three-dimensional image management server 40 generates the simulation result screen 390, and the transmission / reception unit 41 of the three-dimensional image management server 40 transmits the screen information of the simulation result screen 390 to the terminal device 10.

[0275] S217: The transmitting / receiving unit 11 of the terminal device 10 receives screen information from the simulation result screen 390, and the display control unit 13 displays the simulation result screen 390 (see Figure 31).

[0276] S218: After the simulation is complete, the user inputs a screen return command to the terminal device 10 to display the property display screen 380. The input reception unit 12 receives the input.

[0277] S219: In order for the terminal device 10 to connect to the captured image management server 20, the transmitting / receiving unit 11 logs out from the three-dimensional image management server 40.

[0278] S220: The user enters a login operation into the terminal device 10. This login is for the captured image management server 20. The input reception unit 12 of the terminal device 10 accepts the login operation. Any existing login method is acceptable. Here, we assume that the login was successful. Later, the user will log in to the 3D image management server 40, so the sending / receiving unit 11 may send the URL of the 3D image management server 40 to the 3D image management server 40 for redirection.

[0279] S221: The transmitting / receiving unit 11 of the terminal device 10 sends a request for property management information and live images 251 to the captured image management server 20, specifying the property identification information.

[0280] S222: The transmitting / receiving unit 21 of the captured image management server 20 receives a request for property management information and live images 251, and the storage / reading unit 29 searches the captured image information management DB 2001 using the property identification information. The screen generation unit 22 of the captured image management server 20 generates a property management screen 210 (see Figure 11) that displays the property management information and live images 251, and the transmitting / receiving unit 21 transmits the screen information of the property management screen 210 to the terminal device 10.

[0281] Furthermore, the transmitting / receiving unit 21 transmits an image request program to the terminal device 10 in response to requests for property management information and live images 251, so that the terminal device 10 can acquire three-dimensional image information.

[0282] S222: The transmitting / receiving unit 11 of the terminal device 10 receives screen information and an image request program for the property management screen 210. The display control unit 13 displays the property management screen 210. As a result, the property management information and the live image 251 are displayed.

[0283] S223: The user enters a login operation into the terminal device 10. The image request program should prompt the user to log in to the three-dimensional image management server 40. This login is for the three-dimensional image management server 40. The input reception unit 12 of the terminal device 10 accepts the login operation. The login operation may be omitted by using single sign-on or similar methods.

[0284] S224: Since the property's 3D image information has been displayed in the past, the transmitting / receiving unit 11 of the terminal device 10 can send a request for the property's 3D image information to the 3D image management server 40 by specifying the property's identification information, even if the user does not perform an operation to request the property's 3D image information. However, the user may specify the property identification information again.

[0285] S225: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives a request for three-dimensional image information of an object. The storage / reading unit 49 of the three-dimensional image management server 40 searches the three-dimensional image information management DB 4001 using the object identification information and obtains the three-dimensional image information of each item. The processing unit 47 requests the screen generation unit 42 to generate a screen containing the object management information and the three-dimensional image information of the object. The screen generation unit 42 generates an object display screen 380 in which the object management information and the three-dimensional image information of each item are arranged. The transmitting / receiving unit 41 transmits the three-dimensional image information of the object display screen 380 to the terminal device 10. The three-dimensional image information of each item is three-dimensional image information in which all items included in the object are placed on the object, and the user can arbitrarily change the viewpoint.

[0286] S226: The transmitting / receiving unit 11 of the terminal device 10 receives three-dimensional image information of the property display screen 380, and the display control unit 13 displays the property display screen 380 (see Figure 30).

[0287] <<Screen example>> Figure 30 is an example of the property display screen 380 of this embodiment. The explanation of Figure 30 mainly describes the differences from Figure 19. The property display screen 380 in Figure 30 has a simulation execution button 243. Also, no input information (question text 234) has been entered. When the user presses the simulation execution button 243, the three-dimensional image management server 40 executes the simulation.

[0288] Note that the screen shown in Figure 30, which displays property management information (such as the room number and item name of the property) and three-dimensional image information 222 of the property, is an example of the first display screen.

[0289] Figure 31 shows an example of the simulation results screen 390. The simulation results screen 390 displays the simulation results performed on the three-dimensional image information 222 of the property. Property management information and live images 251 are not displayed on the simulation results screen 390. This is because the terminal device 10 logged directly into the three-dimensional image management server 40.

[0290] The diagram also shows three simulation results, 271-273, but these numbers are just examples. For example, simulation result 271 identifies a cylinder and points out, "The cylinder is in the path of movement." Simulation result 272 identifies a cylinder and points out, "It may not pass through the opening." Simulation result 273 identifies a storage box and points out, "It may be exposed to the air conditioner's airflow."

[0291] Furthermore, the simulation results screen 390 has a button 244 that returns to the property display screen 380. Pressing the button 244 that returns to the property display screen 380 corresponds to a screen return instruction. By pressing the button 244 that returns to the property display screen 380, the user can transition to the property display screen 380 shown in Figure 30.

[0292] Note that the screen shown in Figure 31, where property management information (such as the room number and item name of the property) is not displayed but the three-dimensional image information 222 of the property is displayed, is an example of a second display screen.

[0293] <Main effects> According to this embodiment, when a user executes a function that is only available on the 3D image management server 40, such as a simulation function, the terminal device 10 logs out of the captured image management server 20 and logs in to the 3D image management server 40. Therefore, the functions available on the 3D image management server 40 can be provided to the user while they are logged into the 3D image management server 40.

[0294] [Fourth Embodiment] In this embodiment, a three-dimensional image management server 40 that generates images from captured images and text information will be described.

[0295] Figure 32 is a functional configuration diagram illustrating an example of the functions of the three-dimensional image management server 40, the captured image management server 20, and the terminal device 10 in the information processing system 100 according to this embodiment. Note that the explanation of Figure 32 mainly focuses on the differences from Figure 3.

[0296] The three-dimensional image management server 40 in Figure 32 further includes an image generation unit 53, and an image generation model 4006 is constructed in the storage unit 4000 of the three-dimensional image management server 40. The other configurations may be the same as in Figure 3.

[0297] The image generation unit 53 is an example of an image generation means, and is implemented by instructions from the CPU 401 shown in Figure 2. It generates image information by inputting text data or text data into the image generation model 4006.

[0298] Image generation model 4006 is a machine learning model (generative AI) that generates images from text data, or from text data and images. Image generation model 4006 is trained using training data that includes text data and images. This training data includes, for example, training text data, or text data and images as input, and ground truth images as output. For example, the image generation model 4006 may be trained so that the images it generates when inputting text data, or text data and images, approach the ground truth images included in the training data.

[0299] <Learning Phase> The processing in the learning phase may be the same as in Figure 17. In step S38, the update unit 46 updates the first tacit knowledge model 4004A to learn a correspondence between comments and voice text that were determined to have a low degree of relevance in step S37, and three-dimensional image information or captured images of the item. Alternatively, the update unit 46 updates the tacit knowledge model 4004 to learn a correspondence between comments, voice text, and three-dimensional image information (or captured images) of the item, and captured images (or three-dimensional image information) as output.

[0300] <Inference Phase (Generation of Text Information)> Figure 33 is an example sequence diagram showing the process of generating text and image information. Note that the explanation of Figure 33 mainly focuses on the differences from Figure 20. In Figure 33, step S58-1 is added.

[0301] S58-1: The image generation unit 53 inputs the captured image and the text information created by the large-scale language model to the image generation model 4006 to generate image information. The image generation unit 53 may also obtain the image information created by the image generation model 4006 using the text information created by the large-scale language model without using the captured image.

[0302] The memory / reading unit 49 stores (or overwrites) the text information created by the large-scale language model and the image information created by the image generation model 4006 in the three-dimensional image information management DB 4001, corresponding to the captured image stored in the DB 4001 in step S56.

[0303] S59: The processing unit 47 associates the three-dimensional image information of the item corresponding to the model ID with the generated image information and text information, and requests the screen generation unit 42 to display them. The screen generation unit 42 generates a screen corresponding to the second display area 215 that displays the three-dimensional image information of the item with the generated image information and text information. The transmitting / receiving unit 41 of the three-dimensional image management server 40 transmits screen information of the screen corresponding to the second display area 215 to the terminal device 10. The transmitting / receiving unit 11 of the terminal device 10 receives screen information of the screen corresponding to the second display area 215 transmitted from the three-dimensional image management server 40.

[0304] <Example of the inference phase screen> Figure 34 shows the generated image information displayed on the text information display screen 260. The explanation of Figure 34 mainly focuses on the differences from Figure 22.

[0305] The text information display screen 260 in Figure 34 shows the generated image 261. The generated image 261 is not the captured image 252 described in Figure 23, but rather a generated image produced by the image generation model 4006 based on the captured image 252 and the text information 235. Therefore, the generated image 261 has a marker 263 that indicates the location of the wound.

[0306] <Main effects> In this way, the three-dimensional image management server 40 can generate image information based on an image generation model using captured images and text information.

[0307] [Other application examples] The present invention is not limited to the embodiments specifically disclosed above, and various modifications and changes are possible without departing from the scope of the claims. It goes without saying that the three-dimensional image management server 40 described in this embodiment is just one example, and there are various system configurations depending on the application and purpose.

[0308] For example, in this embodiment, we described an example in which an implicit knowledge model for industries such as civil engineering and construction answers a question, but the implicit knowledge model can be used in any industry where implicit knowledge is effective, such as healthcare, dental care, and investment decisions.

[0309] Furthermore, in this embodiment, the large-scale language model 4005 generates text information based on tacit knowledge comments, but it is also possible to use tacit knowledge comments as text information without using the large-scale language model 4005.

[0310] Furthermore, the first tacit knowledge model 4004A may also be one that takes three-dimensional image information and audio text as input and learns tacit knowledge comments by outputting the input information. In other words, it may take information in different forms, such as images and text, as input.

[0311] Furthermore, the three-dimensional image management server 40 may generate two sets of text information using not only one of the first tacit knowledge model 4004A or the second tacit knowledge model 4004B, but both. In other words, the three-dimensional image management server 40 may generate text information using at least one of the first tacit knowledge model 4004A or the second tacit knowledge model 4004B.

[0312] Furthermore, although this embodiment describes a client-server type information processing system 100, the functions of the three-dimensional image management server 40 may be installed as an application on the terminal device 10. In other words, users may use the functions of this embodiment in a standalone format.

[0313] Furthermore, the configuration examples shown in Figure 3 and other figures are divided according to their main functions to facilitate understanding of the processing performed by the three-dimensional image management server 40. The present invention is not limited by the way the processing units are divided or their names. The processing of the three-dimensional image management server 40 can be further divided into many more processing units depending on the processing content. It can also be divided so that one processing unit includes even more processing.

[0314] Each of the functions of the embodiments described above can be realized by one or more processing circuits. Hereinafter, "processing circuit" as used herein includes processors programmed to execute each function by software, such as processors implemented by electronic circuits, as well as devices such as ASICs (Application Specific Integrated Circuits), DSPs (digital signal processors), FPGAs (field programmable gate arrays), and conventional circuit modules designed to execute each of the functions described above.

[0315] The apparatus described in the examples represents only one of several computing environments for carrying out the embodiments disclosed herein. In one embodiment, the three-dimensional image management server 40 includes multiple computing devices, such as a server cluster. The multiple computing devices are configured to communicate with each other via any type of communication link, including a network or shared memory, and perform the processing disclosed herein.

[0316] Furthermore, the three-dimensional image management server 40 can combine the disclosed processing steps in various ways. Each element of the three-dimensional image management server 40 may be combined into a single device or divided into multiple devices. Also, each processing performed by the three-dimensional image management server 40 may be performed by the terminal device 10.
