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

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

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

[0011] CIM is an abbreviation for Construction Information Modeling, and it is a solution for the civil engineering field (covering all infrastructure such as roads, electricity, gas, water supply, etc.) proposed following BIM, which was being promoted in the architectural field. Similar to BIM, CIM aims to improve and enhance the efficiency of a series of construction production systems by sharing information among relevant parties centered around a 3D model.

[0012] What is important in promoting BIM and CIM implementation is how to utilize the constructed BIM and CIM.

[0013] Specifically, the 3D models restored by BIM and CIM can be utilized not only for design and construction purposes but also for other tasks such as maintenance management and site surveys. That is, not only the usage as design drawings but also other uses such as leaving records in the 3D model and sharing with others can be considered.

[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 two-dimensional 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 may be cases where it is desirable to add a function to a system that includes a first server and terminal devices that hold property management information (such as captured images of properties and audio text), to display images such as 3D models corresponding to the properties.

[0019] One way to achieve this is for the first server to acquire images such as 3D models of the property, but this would require adding functionality to the first server, leading to increased costs.

[0020] Therefore, in this embodiment, the first server processes property management information (captured images of properties, audio text, etc.) and the second server processes images such as 3D models of properties managed by the second server. This allows the user to view the three-dimensional image information and the captured images and audio text acquired from the first server on a single screen on their terminal device. Furthermore, the second server can not only display two pieces of information on the terminal device, but also display tacit knowledge about the property (text information, etc.) generated based on the captured images and three-dimensional image information, in association with the three-dimensional image information. As a result, the terminal device can display the three-dimensional image information and tacit knowledge about the property on a single screen without significantly adding functionality to the first 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 their viewpoint within this three-dimensional image information.

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

[0028] A display screen is, for example, a screen that displays a captured image and three-dimensional image information, or generated information and three-dimensional image information on a single screen. In this embodiment, the screens shown in Figures 13 and 20 are examples.

[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] [First Embodiment] <Example System Configuration> Figure 1 is an overall configuration diagram of an example of an information processing system 100. The information processing system 100 in this embodiment includes a terminal device 10, a shooting device 5, 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.

[0032] 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.

[0033] 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. Furthermore, the 3D image management server 40 may be a server located in an on-premises environment.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] It is preferable that the 3D image management server 40 and the captured image management server 20 are linked to a degree that enables single sign-on. The 3D image management server 40 can communicate with the captured image management server 20 via an API exposed by the captured image management server 20. Alternatively, the 3D image management server 40 and the captured image management server 20 may have a business partnership.

[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 native application dedicated to 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] 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, 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> <<Image management server, captured image management server, terminal device>> Figure 2 is a hardware configuration diagram of an example of the three-dimensional image management server 40, the captured image management server 20, or the terminal device 10 according to this embodiment.

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.

The three-dimensional image management server 40 also has a storage unit 4000 constructed from the HD 404 shown in Figure 2. The storage unit 4000 is an example of a storage means.

[0067] In Figure 3, all functions are installed in a single 3D image management server 40, but the 3D image management server 40 may also be configured to distribute each function across multiple computers.

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 3D model shape information of 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 renders 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. 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 images of the property.

[0078] 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.

[0079] The tacit knowledge model 4004 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. It is a model that enables a computer to 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.

[0080] 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.

[0081] <<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.

[0082] 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)."

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] <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, realized by any of the components shown in Figure 2 operating according to instructions from the CPU 401 following 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] <<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.

[0094] 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.

[0095] <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 S1 to S4 in Figure 6 are repeated.

[0096] S1: 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. The relay device 3 then acquires the video and audio data. The captured image management server 20 has pre-associated device IDs with properties.

[0097] S2: 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.

[0098] S3a: The captured image management server 20 reads the participant IDs of participants in the same conference as the camera 5 from the conference information. The captured image management server 20 also reads the IP addresses of 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 sends 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.

[0099] S3b: 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.

[0100] S4a, 4b: 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.

[0101] S5: Participants A and B (Participant B in the diagram) of 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.

[0102] S6: When the captured image management server 20 receives the 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.

[0103] S7: Relay device 3 receives the capture request and field of view information and transmits it to the shooting device 5.

[0104] S8: 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.

[0105] S9: 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 S3. The storage / reading unit 29 stores the captured image, shooting location, and field of view information in the captured image information management DB 2001.

[0106] 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.

[0107] 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.

[0108] <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, speech-to-text is not used for updating the model and generating text information, but the same learning can be achieved by replacing or adding dialogue Q1, etc., with speech-to-text.

[0109] Figure 7 is an explanatory diagram of what the terminal device 10 displays during text information generation processing and model update processing. Figure 7(a) is an explanatory diagram of the model update processing. 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.

[0110] 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 in response to 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 4004 is updated, allowing the user to obtain useful tacit knowledge comments.

[0111] The identification unit 44 identifies the target image 1100, which is the portion of the display screen 900 excluding the text 1200.

[0112] 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.

[0113] The update unit 46 updates the tacit knowledge model 4004 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, 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.

[0114] Therefore, the tacit knowledge model 4004 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 4004 can learn the correspondence between the image features and the dialogues Q1, A1, Q2, and A2.

[0115] 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.

[0116] 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.

[0117] The identification unit 44 identifies the image 1110 that does not contain the text 1210 as the target image.

[0118] The text information generation unit 45 uses image 1110 to acquire tacit knowledge comments based on the tacit knowledge model 4004. The tacit knowledge model 4004 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, and can identify dialogues Q1, A1, Q2, and A2 related to image 1110. Dialogues Q1, A1, Q2, and A2 become tacit knowledge comments.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] Figure 8(a) is an explanatory diagram of the model update process. Figure 8(a) shows an example in which the tacit knowledge model 4004 is updated with audio information and partial images from a single data provider, rather than a conversation between data providers.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] The update unit 46 updates the tacit knowledge model 4004 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.

[0129] Therefore, the tacit knowledge model 4004 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 content of the work being performed. Thus, the tacit knowledge model 4004 can learn the correspondence between the features of the image and the comments C1-C4.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] The text information generation unit 45 uses the partial image 1100B1 to acquire tacit knowledge comments based on the tacit knowledge model 4004. The tacit knowledge model 4004 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 4004 extracts comments C1 to C4 as tacit knowledge comments.

[0134] 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.

[0135] 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.

[0136] <Action or process> Next, we will describe a method for displaying captured images and three-dimensional image information on a single screen, as an example of processing based on these. In other words, the tacit knowledge model 4004 is not used.

[0137] Figure 9 is a sequence diagram showing an example of a process that generates screen information by arranging both a captured image and three-dimensional image information.

[0138] S11: 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.

[0139] 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.

[0140] S12: 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.

[0141] S13: 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.

[0142] S14: 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 inputs property identification information (for example, V0001, XX Building 2F-N, etc.) for the property whose live image they want to see on the displayed property selection screen 200. The input receiving unit 12 of the terminal device 10 receives the property identification information.

[0143] S15: The transmitting / receiving unit 11 of the terminal device 10 sends a request for live images to the captured image management server 20, specifying the property identification information.

[0144] S16: The transmitting / receiving unit 21 of the captured image management server 20 receives a request for live images, 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 that displays the live images, and the transmitting / receiving unit 21 transmits the screen information of the property management screen 210 to the terminal device 10.

[0145] Furthermore, in response to a request for a live image, the transmitting / receiving unit 21 sends a live image of the object and an image request program to the terminal device 10 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, the terminal device 10 has the function of connecting to the three-dimensional image management server 40 and requesting and displaying three-dimensional image information.

[0146] S17: The transmitting / receiving unit 11 of the terminal device 10 receives the live image, the screen information of the property management screen 210, and the image request program. The display control unit 13 displays the property management screen 210 (see Figure 11). This displays the property management information and the live image. The user requests three-dimensional image information of the property from the displayed property management screen 210 (by pressing the image acquisition button 213). The user can also arbitrarily change the viewpoint of the live image. 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 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.

[0147] Here, the property management screen 210 includes a first display area 214 that displays live images acquired from the captured image management server 20, and a second display area 215 that displays three-dimensional image information of the items acquired from the three-dimensional image management server 40. At step S17, the first display area 214 displays property management information and live images, but nothing is displayed in the second display area 215.

[0148] S18: 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. Alternatively, the user's login operation may be omitted by using, for example, single sign-on.

[0149] S19: The terminal device 10 executes an image request program to request three-dimensional image information. The transmitting / receiving unit 11 then sends the following to the three-dimensional image management server 40: the property identification information of the property selected by the user, the current shooting position of the shooting device 5 (obtained from the image management server 20), and the field of view information specified by the user in step S17. The transmitting / receiving unit 11 may also send the URL of the image management server 20 to the three-dimensional image management server 40 so that the terminal device 10 can be redirected to the image management server 20. The three-dimensional image information of the property is an image of an object placed in the property, which is formed as 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 a two-dimensional plane to generate a planar image. The user can view any object while changing their viewpoint. The transmitting / receiving unit 11 may also send property management information obtained from the image management server 20 to the three-dimensional image management server 40. The image request program receives property management information from a web application connected to the image management server 20, for example, as a URL parameter.

[0150] S20: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives requests for three-dimensional image information of an object, object management information, location information, and field of view information. The storage / reading unit 49 searches the three-dimensional image information management DB 4001 using the object identification information and obtains the 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 the three-dimensional image information by placing a virtual camera at the location information and determining the field of view of the virtual camera based on the field of view information. The screen generation unit 42 generates a screen corresponding to the second display area 215 on which the three-dimensional image information is placed.

[0151] The transmitting / receiving unit 41 transmits 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 of all items included in the property placed on the property, and the user can change the viewpoint as they wish.

[0152] S21: 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 a three-dimensional image display screen 220 including the first display area 214 and the second display area 215 (see Figure 12). At step S21, only the three-dimensional image information of each item is displayed in the second display area 215, but the first display area 214 displays, for example, a live image, so that the live image and the three-dimensional image information of the item are displayed on the same screen from the same viewpoint. However, the viewpoint of both the live image and the three-dimensional image information can be changed.

[0153] 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.

[0154] S22: When the user presses the information display button 225, the transmitting / receiving unit 11 of the terminal device 10 transmits information identifying the item (e.g., model ID), shooting location information, and field of view information to the three-dimensional image management server 40.

[0155] S23: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives information identifying an item, shooting location information, and field of view information. 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 and audio text from the captured image management server 20.

[0156] S24: 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 three-dimensional 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.

[0157] S25: 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 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.

[0158] S26: When the transmitting / receiving unit 11 of the terminal device 10 receives the captured image and audio text, it sends 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 S23. Upon receiving the captured image and audio text, the storage / reading unit 49 associates the captured image with the model ID received in step S22 and saves it to the three-dimensional image information management DB 4001. The storage / reading unit 49 may also save the audio text.

[0159] S27: When the processing unit 47 receives the captured image and audio text, it associates the three-dimensional image information, captured image, and audio text from step S20 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, captured image, and audio text in association with each other. The screen generation unit 42 may also perform an update process to add only the captured image and audio text to the screen corresponding to the second display area 215 (since the three-dimensional image information has already been displayed). The transmitting / receiving unit 41 transmits the screen information of the screen corresponding to the second display area 215 to the terminal device 10.

[0160] S28: 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 a captured image display screen 230 including the first display area 214 and the second display area 215 (see Figure 13). In step S28, the first display area 214 displays a live image, as in step S21, and the second display area 215 displays three-dimensional image information of the item, a captured image, and audio text.

[0161] <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.

[0162] 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 belonging to the property identified by the property identification information and a live image 251. The live image 251 is a real-time video. 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 three-dimensional image display screen 220 is displayed.

[0163] The second display area 215 is an area other than the first display area 214, and its display may be implemented by a program on a web application, such as an iframe.

[0164] Figure 12 shows an example of a three-dimensional image display screen 220. The three-dimensional image display screen 220 includes a first display area 214 and a second display area 215. A live image 251 is displayed in the first display area 214 of the three-dimensional image display screen 220. The live image 251 is a real-time video.

[0165] The second display area 215 of the three-dimensional image display screen 220 displays three-dimensional image information 222. 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 those specified by the user for the live image 251, or they can remain at the initial state. Since the three-dimensional image information 222 is an image projected from a three-dimensional model, the user can change the field of view information.

[0166] Furthermore, the user can select the item for which they want to display the captured image and audio text from the three-dimensional image information 222 using the mouse cursor 212. This determines the coordinates of the item as information to identify the item. Also, as the user changes the viewpoint or zooms in, the field of view of the three-dimensional image information 222 is determined. For example, a table can be zoomed in and displayed. The shooting position of the shooting device 5 is also acquired. When the user presses the information display button 225, the captured image display screen 230 is displayed. Note that the information display button 225 is used not only to display the captured image and audio text, but also to display text information generated based on tacit knowledge comments, as will be described later. Furthermore, when the user presses the information update button 226, the tacit knowledge model 4004 is updated.

[0167] Furthermore, since the live image 251 is a wide-field image, the user can change the field of view information. The user may also specify the field of view of the live image 251 in order to identify the item from which to acquire the captured image and audio text. In this case as well, the three-dimensional image management server 40 can identify the item selected by the user based on the position and field of view information of the shooting device 5. However, if it is three-dimensional image information 222, the terminal device 10 can uniquely identify the item by the coordinates of the mouse pointer relative to the 3D model.

[0168] In Figure 12, the area (floor area) 224 is displayed as information about the property. The area (floor area) 224 may be a measured value or it may be included in the captured image information management table.

[0169] As shown in Figure 12, the terminal device 10 was able to display the live image 251 managed by the captured image management server 20 and the three-dimensional image information 222 of the property managed by the three-dimensional image management server 40 on a single screen. Users can view the live image 251 while checking the three-dimensional image information 222 of the property. Users can also change the field of view information to view both.

[0170] Figure 13 shows an example of a captured image display screen 230. The captured image display screen 230 includes a first display area 214 and a second display area 215. A live image 251 is displayed in the first display area 214.

[0171] In Figure 13, the three-dimensional image information 223 of a table selected by the user as an example of an item is displayed in the second display area 215. The second display area 215 also displays a captured image 252. Since the field of view of the captured image 252 is close to that of the three-dimensional image information 223 of the table, the table as a three-dimensional image information 223 and the table as a captured image 252 are displayed from almost the same viewpoint. The captured image 252 is obtained from the captured image information management table. If there are multiple captured images with the same field of view in the captured image information management table, this captured image 252 is the most recent captured image. Alternatively, multiple captured images may be displayed in reverse chronological order.

[0172] In addition, the second display area 215 displays the audio text 232 associated with the captured image. One example of the audio text 232 is "This is the initial state." In this way, the terminal device 10 can display a live image 251 with almost the same field of view, three-dimensional image information 223, the captured image 252, and the audio text 232 associated with the captured image 252, all on a single screen.

[0173] The field of view of the live image 251 in the first display area 214 and the field of view of the captured image 252 do not necessarily match. This is because, in Figure 12, the user selected an item from the three-dimensional image information 223 as the method for specifying an item. If the user selects an item from the live image 251 in Figure 12, the field of view of the live image 251 and the field of view of the captured image 252 will be the same.

[0174] As shown in Figure 14, if the user selects a different item using three-dimensional image information, the information displayed in the second display area 215 will also correspond to that item. Figure 14 shows the captured image display screen 230 when the user has selected a different item. In Figure 14, the live image 253 is displayed in the first display area 214. The user has enlarged the rectangular prism in the field of view. As a result, the second display area 215 displays the latest captured image 254 (an example of the second predetermined area image) and the second newest captured image 255 (an example of the second predetermined area image) of the rectangular prism item.

[0175] Furthermore, as shown in Figure 14, the terminal device 10 may display the second most recent captured image in the second display area 215. Any captured image managed by the captured image management server 20 can be displayed in the second display area 215.

[0176] The terminal device 10 may have a function that links the three-dimensional image information 227 to the field of view of the live image 253. In other words, if the user manually specifies the field of view of the live image 253, the three-dimensional image information 227 will be displayed at the same field of view in real time. The same applies if the user manually specifies the field of view of the three-dimensional image information 227. As a result, the live image 253, the latest captured image 254, the second newest captured image 255, and the three-dimensional image information 227 are all displayed at the same field of view.

[0177] Furthermore, the audio text 256 associated with the most recent captured image 254 in the captured image management information table is displayed. In addition, the audio text 257 associated with the second most recent captured image 255 in the captured image management information table is also displayed. The second display area 215 may display not just two, but all captured images saved in the captured image management information table.

[0178] <Example of an image management server retrieving captured images and audio / text from a captured image management server> In Figure 9, the terminal device 10 acquires the captured image and comments from the captured image management server 20, and the three-dimensional image management server 40 acquires them from the terminal device 10. However, it is also possible for the three-dimensional image management server 40 to directly acquire the captured image and audio text from the captured image management server 20.

[0179] Figure 15 is a sequence diagram (modified) showing an example of a process that generates screen information by arranging both a captured image and three-dimensional image information. Note that Figure 15 may mainly explain the differences from Figure 9. First, the processing in steps S11 to S22 can be the same as in Figure 9.

[0180] S23: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives information identifying an item, shooting location information, and field of view information. The transmitting / receiving unit 41 specifies the shooting location information and field of view information and requests the captured image and audio text from the captured image management server 20.

[0181] The transmitting / receiving unit 21 of the captured image management server 20 receives requests for captured images and audio text. The storage / reading unit 29 retrieves from the captured image information management DB 2001 a record with the same location information as the shooting location information, a captured image captured with the closest field of view information to the received field of view information, and the audio text associated with this captured image. The transmitting / receiving unit 21 sends the captured image and audio text to the three-dimensional image management server 40. The captured image management server 20 may also capture from the latest live image using the shooting location information and field of view information.

[0182] S26: The three-dimensional image management server 40 receives the captured image and audio text as a response to the request in step S23.

[0183] The subsequent processing can be the same as in Figure 9. With processing as shown in Figure 15, the processing required for the terminal device 10 to change the connection destination can be reduced, thus shortening the time until the captured image display screen 230 is displayed.

[0184] <Main effects, etc.> In this embodiment, the three-dimensional image management server 40 performs processing based on captured images, audio text, and three-dimensional image information, so the terminal device 10 can display the three-dimensional image information and the second display area 215 of the captured image display screen 230, which includes the captured images and audio text corresponding to the three-dimensional image information. The three-dimensional image management server 40 can perform processing based on the captured images and audio text managed by the captured image management server 20 and the three-dimensional image information managed by the three-dimensional image management server 40 without adding processing functions to the captured image management server 20.

[0185] Furthermore, the captured image management server 20 may perform some of the processing based on the captured images and audio text managed by the captured image management server 20 and the three-dimensional image information managed by the three-dimensional image management server 40. Even in this case, the processing load on the captured image management server 20 is reduced compared to performing all the processing based on the captured images and audio text managed by the captured image management server 20 and the three-dimensional image information managed by the three-dimensional image management server 40 on the captured image management server 20 side.

[0186] Here, the three-dimensional image information, the captured image, and the audio text may be displayed in a way that they do not overlap with each other, or they may be displayed in a way that they overlap with each other. Furthermore, the first display area 214 and the second display area 215 may be displayed so as not to overlap with each other, or they may be displayed so as to overlap with each other. Furthermore, the first display area 214 and the second display area 215 may each be divided into multiple sections for display, and the divided sections may be displayed in a mixed manner.

[0187] [Second Embodiment] In this embodiment, a three-dimensional image management server 40 is described that acquires tacit knowledge comments from a tacit knowledge model using three-dimensional image information and captured images, and generates text information based on the tacit knowledge comments.

[0188] In this embodiment, we will explain the process assuming that the hardware configuration diagram in Figure 2 and the functional block diagram in Figure 3, as described in the above embodiment, can be used as reference.

[0189] <Action or process> <<Learning Phase (Model Update)>> First, we will explain the model update process in which the tacit knowledge model 4004 learns data, referring to Figure 16. Figure 16 is a sequence diagram showing an example of the model update process. In explaining Figure 16, we will mainly explain the differences from Figure 9. The processes in steps S31 to S40 can be the same as in Figure 9.

[0190] S41: In step S41, in addition to the processing in step S21, the user inputs comments (text information, audio) about the item into the terminal device 10, as explained in Figures 7 and 8. Comments are sometimes referred to as input information. This input information may be tacit knowledge comments. The input information may also include caption comments that describe the item.

[0191] S42: When the user presses the information update button 226, the transmitting / receiving unit 11 of the terminal device 10 transmits information identifying the item, shooting location information, field of view information, and input information to the three-dimensional image management server 40.

[0192] The subsequent steps S43 to S46 can be the same as in Figure 9.

[0193] S47: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives the captured image and audio text. The determination unit 43 obtains the caption comment identified by the model ID (identified by information that identifies the item) 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 S42. 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 S42, or it may divide the comments included in the input information received in step S42 into multiple parts and determine the degree of relevance between the obtained caption comment and each divided comment.

[0194] S48: The update unit 46 updates the caption model 4003 by associating the input information deemed highly relevant in step S47 with the model ID as a caption comment. The update unit 46 also updates the tacit knowledge model 4004 using the input information and audio text deemed less relevant in step S47, along with the three-dimensional image information and captured image of the item identified by the field of view information in step S42, as training data. In other words, the correspondence between the three-dimensional image information and captured image of the item and the audio text and input information 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 and where, or the content of the work being performed. Therefore, the tacit knowledge model 4004 can learn the correspondence between the features of the three-dimensional image information and captured image of the item and the audio text and input information.

[0195] Note that both speech-to-text and input information are not necessarily required; the tacit knowledge model 4004 can be updated with at least one of them.

[0196] Furthermore, in Figure 16, the 3D image management server 40 acquires the captured image and audio text from the terminal device 10, but as shown in Figure 15, they may also be acquired from the captured image management server 20.

[0197] <<Example of a screen during the learning phase>> The screen displayed by terminal device 10 during the learning phase will be the same as in Figures 10 to 12, but in Figure 12, the user can input information. Furthermore, the information corresponding to Figure 13, which displays the captured image and audio text, will be displayed in the inference phase described below.

[0198] Figure 17 shows an example of a three-dimensional image display screen 220 displayed by the terminal device 10. The three-dimensional image display screen 220 in Figure 17 includes a first display area 214 and a second display area 215. The first display area 214 displays a live image 251 and information about the property, including its size (floor area) 224. The second display area 215 displays three-dimensional image information of the property 222 and input information 241 entered by the user, which states, "This table has an unstable center of gravity, so it is best not to place anything weighing more than 50 kg on it." The user entered the input information 241 by specifying (pressing) the table. As a result, the captured image and audio text, which are associated with the shooting position information of the shooting device 5 and the field of view information when the table was specified, are obtained from the captured image management server 20.

[0199] The three-dimensional image management server 40 can update the tacit knowledge model 4004 using the input information 241, the audio text associated with the captured image, the three-dimensional image information 223, and the captured image. Note that the area (floor area) 224, as information about the property, can be used as a caption comment.

[0200] <Inference Phase (Generation of Text Information)> Next, with reference to Figure 18, the text information generation process using the tacit knowledge model 4004 will be explained. Figure 18 is a sequence diagram illustrating an example of the text information generation process. Note that the explanation of Figure 18 will mainly focus on the differences from Figure 9. The processes in steps S31 to S46 are the same as in Figure 9. However, in step S41, the user entered a question about the item (see Figure 19). The user also pressed the information display button 225.

[0201] S51: The transmitting / receiving unit 41 of the three-dimensional image management server 40 receives the captured image and audio text. 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 tacit knowledge model 4004. The tacit knowledge model 4004 can extract features of the three-dimensional image information and captured image of the item and identify at least one of the audio text and input information corresponding to these features. The tacit knowledge model 4004 extracts at least one of the audio text and input information as tacit knowledge comments. S52: Next, the text information generation unit 45 obtains text information created by the large-scale language model 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 contained in the input information (question text) into text information, and the text information generated by the text information generation unit 45 may be either speech information or text information.

[0202] The text information generation unit 45 may generate text information without using any speech text or input information. 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.

[0203] 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.

[0204] S53: The processing unit 47 associates the three-dimensional image information, captured image, and text information of the item corresponding to the model ID (identified by information that identifies the item) and requests the screen generation unit 42 to display them. The screen generation unit 42 generates a screen corresponding to a second display area 215 that includes the three-dimensional image information, captured image, and further displays the generated text information.

[0205] The screen generation unit 42 may perform an update process that adds only 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. The transmitting / receiving unit 11 of the terminal device 10 receives the screen information of the screen corresponding to the second display area 215 transmitted from the three-dimensional image management server 40.

[0206] S54: The display control unit 13 of the terminal device 10 displays a captured image display screen 230 including a first display area 214 and a second display area 215 (see Figure 20). Three-dimensional image information, a captured image, and text information are displayed in the second display area 215. The conversion unit 15 may convert the received text information into audio information, and the audio control unit 14 may play the converted text information through the speaker 109a. Alternatively, if the received text information is audio information, the text information may be played through the speaker 109a, or the conversion unit 15 may convert the received text information into character information and display the converted text information on the display 106a.

[0207] In Figure 18, the 3D image management server 40 acquires the captured image and audio text from the terminal device 10, but they may also be acquired from the captured image management server 20 as shown in Figure 15.

[0208] <<Example of the inference phase screen>> The screen displayed by the terminal device 10 during the inference phase will be the same as in Figures 10 to 13, but in Figure 12, the user can input a question.

[0209] Figure 19 shows an example of a three-dimensional image display screen 220 in the inference phase. The three-dimensional image display screen 220 includes a first display area 214 and a second display area 215. Figure 19 has the same configuration as Figure 12, but the user has entered a question as input information. The second display area 215 displays three-dimensional image information 222 of the property. The user also clicked on the three-dimensional image information 223 of the table from the three-dimensional image information 222 and entered input information (question) 234 specifying the table. For example, the input information (question) 234 in Figure 19 is "There is a scratch on the table, what should I do?" Along with this input information 234, the user clicks the information display button 225 to request the generation of text information using the tacit knowledge model.

[0210] Figure 20 shows an example of text information displayed on the captured image display screen 230. The captured image display screen 230 includes a first display area 214 and a second display area 215. The second display area 215 displays three-dimensional image information 223 of a table, a captured image 252, and text information 235 corresponding to the three-dimensional image information of the table and the captured image. This 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 more, it will be polished." The text information 235 is generated by the large-scale language model 4005 from the three-dimensional image information of the item, the captured image, the voice text, and the question. For example, if a scratch is detected in the captured image 252 of the item, an implicit knowledge comment regarding the scratch on this item is extracted. This implicit knowledge comment, the question regarding the scratch, and the voice text identifying the current state of the scratch are input to the large-scale language model 4005, so that appropriate text information corresponding to the current scratch can be generated.

[0211] Text information 235 is not the speech text itself, but it includes at least one of the following: tacit knowledge comments generated by a tacit knowledge model that has learned speech text, and text information generated by a large-scale language model 4005 based on the input information, speech text, and tacit knowledge comments. Furthermore, text information 235 can be described as the processing result of processing based on speech text, three-dimensional image information, and captured images.

[0212] [Third Embodiment] In this embodiment, a three-dimensional image management server 40 that generates images from captured images and text information will be described.

[0213] Figure 21 is an example 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. Note that the explanation of Figure 21 mainly focuses on the differences from Figure 3.

[0214] The three-dimensional image management server 40 in Figure 21 further includes an image generation unit 48, 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.

[0215] The image generation unit 48 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.

[0216] 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.

[0217] <Learning Phase> The processing in the learning phase may be the same as in Figure 16. In step S48, the update unit 46 updates the tacit knowledge model 4004 to learn a correspondence between comments and voice text that were determined to have low relevance in step S47, and 3D 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 3D image information (or captured images) of the item, and captured images (or 3D image information) as output.

[0218] <Inference Phase (Generation of Text Information)> Figure 22 is an example sequence diagram showing the process of generating text and image information. Note that the explanation of Figure 22 mainly focuses on the differences from Figure 18. Step S52-1 is added in Figure 22.

[0219] S52-1: The image generation unit 48 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 48 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.

[0220] 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 S46.

[0221] S53: The processing unit 47 associates the three-dimensional image information of the item corresponding to the model identification information 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, 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.

[0222] <Example of the inference phase screen> Figure 23 shows the generated image information displayed on the captured image display screen 260. The explanation of Figure 23 mainly focuses on the differences from Figure 20.

[0223] The captured image display screen 260 in Figure 23 shows the generated image 261. The generated image 261 is not the captured image 252 described in Figure 20, 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.

[0224] <Effects of generating text information using captured images> This invention will explain the effects of generating text information using captured images.

[0225] 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.

[0226] 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.

[0227] 3. This embodiment (three-dimensional image information, captured image, audio text) • Learning Phase Input images: Three-dimensional image information and past 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, the effect of learning audio text is "Be careful when applying tape to corners as it may cause cracks to form."

[0228] 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, the effect of learning the audio text is "Please be careful when applying tape to corners as cracks may occur."

[0229] <Multimodal> Several examples of combinations of input information and tacit knowledge comments are described. While the model described above assumed a large-scale language model, this embodiment can utilize a multimodal model that takes multiple data formats (images, text, gestures, etc.) as input and outputs them in a predetermined data format. • When the input information is a string, and content other than text information is generated as an implicit knowledge comment. Enter text to generate an image Enter text to generate a video. Enter text to generate speech. Enter a string of text to generate a 3D model. • When input information includes both strings and non-strings, and text information is generated as an implicit knowledge comment. Enter an image and text to generate text information. Enter a 3D model and text to generate text information. Input speech and text to generate text information. • When input information includes both text and non-textual content, and non-textual content is generated as an implicit knowledge comment. Enter an image and text to generate an image. Enter a video and text to generate a video. Enter a 3D model and text to generate a 3D model. Input speech and text to generate speech. <Main effects> In this embodiment, the image management server updates the tacit knowledge model based on three-dimensional image information, captured images, and audio text, so that the terminal device 10 can display the three-dimensional image information and tacit knowledge comments corresponding to the acquired captured images and audio text. Even if captured images and audio text cannot be acquired when generating text information, the tacit knowledge model can output tacit knowledge comments that take the input information into account based on the acquired three-dimensional image information.

[0230] [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.

[0231] 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.

[0232] 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.

[0233] Furthermore, the tacit knowledge model 4004 may also be trained to take three-dimensional image information and audio text as input, and output tacit knowledge comments using the input information. In other words, the tacit knowledge model 4004 may take information in different forms, such as images and text, as input.

[0234] 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.
