Description

[Technical Field]

[0001] The present disclosure relates to an information processing device, a screen creation method, a program, and an information processing system. [Background technology]

[0002] In recent years, wide-field-of-view images (hereinafter referred to as "wide-field-of-view images") with a wide viewing angle, such as a 360-degree image (also called a celestial sphere image, omnidirectional image, or panoramic image) capturing an entire 360-degree surrounding area, have become known as an imaging range that includes areas that cannot be fully confirmed with a normal angle of view. When attempting to display such a wide-field-of-view image in its entirety on a display terminal, the wide-field-of-view image is curved and difficult to see, so a predetermined area image showing a predetermined area in the wide-field-of-view image is displayed on the display terminal, and the user views the predetermined area image (see Patent Document 1). Summary of the Invention [Problem to be solved by the invention]

[0003] However, it is difficult for a user to understand what the predetermined area image was taken of and where it was taken just by viewing the predetermined area image within the displayed range.

[0004] In addition, the camera captures an object from a 360-degree angle around the camera in one shot from the camera's position, but it cannot capture the object from all directions. Therefore, even if the object is within the shooting range, it cannot capture the back side of the object, so the user cannot grasp the state of the back side of the object.

[0005] The above-mentioned problems also exist when the captured image is not a curved image such as a wide-field image.

[0006] The present disclosure has been made in consideration of the above circumstances, and aims to improve user convenience by complementing captured images obtained by photography. [Means for solving the problem]

[0007] The disclosure of claim 1 is an information processing device having a creation unit that creates a screen including a captured image display area that displays a predetermined area image, which is a predetermined area in a captured image obtained by capturing an object with a capturing device, and a three-dimensional image display area that displays at least a portion of a three-dimensional image aligned with the captured image, and a processing unit that performs processing to associate the capturing position of the captured image, the predetermined area image, and text information, wherein the creation unit creates the screen including an image corresponding to the capturing position associated with the predetermined area image and the text information, at a position corresponding to the capturing position in the three-dimensional image display area. [Effects of the Invention]

[0008] As described above, according to the present disclosure, an advantage is achieved in that convenience for users can be improved by creating an image that complements a captured image obtained by photography. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] [Overview of spherical images] A method for generating a spherical image will be described with reference to Fig. 1 to Fig. 8. A spherical image is also called a spherical panoramic image or a 360° panoramic image, and is an example of a wide-field video with a wide viewing angle. Wide-field images also include simple panoramic images of about 180°.

[0012] First, the appearance of the imaging device 10 will be described using Fig. 1. The imaging device 10 is a digital camera for obtaining captured images that are the basis for creating a spherical image. Fig. 1(a) is a left side view of the imaging device, Fig. 1(b) is a front view of the imaging device, and Fig. 1(c) is a plan view of the imaging device.

[0013] As shown in Fig. 1(a), the photographing device 10 is small enough to be held in one hand. As shown in Figs. 1(a), 1(b), and 1(c), an image sensor 103a is provided on the front side (front side) of the upper portion of the photographing device 10, and an image sensor 103b is provided on the rear side (rear side). As shown in Fig. 1(b), an operation unit 115 such as a shutter button is provided on the front side of the photographing device 10.

[0014] Next, a usage situation of the imaging device 10 will be described with reference to FIG. 2. Note that FIG. 2 is an image diagram of the imaging device in use. As shown in FIG. 2, the imaging device 10 is communicably connected to a relay device 3 installed on some kind of stand 2, and is used to capture surrounding subjects, scenery, and the like. In this case, two hemispherical images can be obtained by capturing images of subjects around the user using the imaging element 103a and the imaging element 103b shown in FIG. 1. Note that if the omnidirectional image captured by the imaging device 10 is not to be transmitted to other communication terminals or systems, the relay device 3 is not necessary.

[0015] Next, an outline of processing until a celestial sphere image is created from an image captured by the image capturing device 10 will be described with reference to Figs. 3 and 4. Fig. 3(a) is a diagram showing a hemispherical image (front side) captured by the image capturing device, Fig. 3(b) is a diagram showing a hemispherical image (rear side) captured by the image capturing device, and Fig. 3(c) is a diagram showing an image expressed by equirectangular projection (hereinafter referred to as "equirectangular projection image"). An image expressed by Mercator projection or the like (hereinafter referred to as "Mercator image") may also be used. Fig. 4(a) is a conceptual diagram showing a state in which a sphere is covered with an equirectangular projection image, and Fig. 4(b) is a diagram showing a celestial sphere image. The "equirectangular projection image" is an equirectangular celestial sphere image as an example of the wide-field-of-view image described above.

[0016] As shown in Fig. 3(a), the image obtained by the image sensor 103a becomes a hemispherical image (front side) curved by a wide-angle lens 102a such as a fisheye lens, which will be described later. Also, as shown in Fig. 3(b), the image obtained by the image sensor 103b becomes a hemispherical image (rear side) curved by a wide-angle lens 102b such as a fisheye lens, which will be described later. Then, the image capturing device 10 combines the hemispherical image (front side) with a hemispherical image (rear side) flipped 180 degrees to create an equirectangular projection image EC as shown in Fig. 3(c).

[0017] The image capturing device 10 then uses software such as OpenGL ES (Open Graphics Library for Embedded Systems) to apply an equirectangular projection image EC to cover the spherical surface as shown in FIG. 4( a), thereby creating a celestial sphere image CE as shown in FIG. 4( b). In this way, the celestial sphere image CE is represented as an image in which the equirectangular projection image EC faces the center of the sphere. OpenGL ES is a graphics library used to visualize 2D (two-dimensional) and 3D (three-dimensional) data. OpenGL ES is merely an example of software that performs image processing, and the celestial sphere image CE may be created by other software. The celestial sphere image CE may be a still image or a video. While the image capturing device 10 has been described as generating a celestial sphere image, other devices (such as the communication control device 5 or the communication terminals 7 and 9) may perform similar image processing or some of the image processing steps.

[0018] Then, by using OpenGL ES (Open Graphics Library for Embedded Systems), the equirectangular projected image EC is pasted to cover the spherical surface as shown in Fig. 4(a), and a celestial sphere image CE is created as shown in Fig. 4(b). In this way, the celestial sphere image CE is expressed as an image in which the equirectangular projected image EC faces the center of the sphere. Note that OpenGL ES is a graphics library used to visualize 2D (2-Dimensions) and 3D (3-Dimensions) data.

[0019] As described above, the spherical image CE is an image pasted to cover the spherical surface, which gives a sense of incongruity to people when they view it. Therefore, the communication terminals 7 and 9 can display a predetermined region (hereinafter referred to as a "predetermined region image"), which is a partial region of the spherical image, as a flat image with little curvature (distortion), thereby enabling a display that does not give a sense of incongruity to people. This will be described with reference to FIGS. 5 to 8.

[0020] Fig. 5 is a diagram showing the positions of a virtual camera and a predetermined area when the celestial sphere image is a three-dimensional sphere. The virtual camera IC1 corresponds to the position of a virtual viewpoint of a user viewing the celestial sphere image CE displayed as a three-dimensional sphere. In Fig. 6, (a) is a three-dimensional perspective view of Fig. 5, (b) is a diagram showing the predetermined area image in the state of (a) displayed on the display, (c) is a diagram showing the predetermined area after the viewpoint of the virtual camera IC1 in (a) is changed, and (d) is a diagram showing the predetermined area image in the state of (c) displayed on the display.

[0021] If the celestial sphere image CE generated in this manner is a three-dimensional sphere CS, the virtual camera IC1 is located inside the celestial sphere image CE as shown in Fig. 5. A predetermined area T in the celestial sphere image CE is an imaging area of ​​the virtual camera IC1, and is specified by angle-of-view information (also referred to as "area information") that indicates the imaging direction and angle of view of the virtual camera IC1 in a three-dimensional virtual space including the celestial sphere image CE.

[0022] Zooming of the predetermined region T can also be expressed by moving the virtual camera IC1 closer to or farther away from the celestial sphere image CE. The predetermined region image Q is an image of the predetermined region T in the celestial sphere image CE. Therefore, the predetermined region T can be specified by the angle of view a and the distance f from the virtual camera IC1 to the celestial sphere image CE.

[0023] Furthermore, when the virtual viewpoint of the virtual camera IC1 is moved (also referred to as "changed") to the right (left as one faces the drawing) from the state of Fig. 6(a) as shown in Fig. 6(c), the predetermined area T in the omnidirectional image CE is moved to the predetermined area T' accordingly, and the predetermined area image Q displayed on the predetermined display is changed to the predetermined area image Q'. As a result, the image shown in Fig. 6(b) is changed to the image shown in Fig. 6(d) and displayed on the predetermined display.

[0024] Next, the relationship between the angle of view information and the image of the predetermined area T will be described with reference to Fig. 7 and Fig. 8. Fig. 7 is a diagram showing points in a three-dimensional Euclidean space using spherical coordinates. Fig. 8 is a conceptual diagram showing the relationship between the predetermined area and a point of interest (center point).

[0025] Here, the coordinates of an arbitrary position when the center point CP shown in Fig. 7 is expressed in a spherical polar coordinate system are (r, θ, φ). (r, θ, φ) are the radius vector, polar angle, and azimuth angle, respectively. The radius vector r is the distance from the origin of the three-dimensional virtual space including the celestial sphere image CE to an arbitrary point (the center point CP in Fig. 8), and is equal to the distance f shown in Fig. 8.

[0026] Furthermore, as shown in FIG. 8, when the center of a predetermined area T, which is the imaging area of ​​the virtual camera IC1, is considered to be the center point CP in FIG. 7, the trigonometric function shown in the following (Equation 1) generally holds. (L / f) = tan(a / 2) (Equation 1) Note that f is the distance from the virtual camera IC1 to the center point CP. L is the distance between any vertex of the predetermined area T and the center point CP (2L is the diagonal). a is the angle of view. In this case, the angle of view information for identifying the predetermined area T can be expressed by pan(θ), tilt(φ), and fov(a). Note that zooming of the predetermined area T can be expressed by widening or narrowing the range (arc) of the angle of view a.

[0027] [Communication system overview] Next, an overview of the communication system 1 according to the embodiment will be described with reference to Fig. 9. Fig. 9 is a schematic diagram of the communication system according to the embodiment.

[0028] As shown in Fig. 9, the communication system 1 of this embodiment is composed of an imaging device 10, a relay device 3, a communication terminal 7, and communication terminals 9a and 9b. The communication terminals 9a and 9b are collectively referred to as "communication terminal 9." The communication control device 5, the communication terminals 7, and the communication terminals 9 are also examples of information processing devices. The communication terminals 7 and 9 may also be referred to as "display terminals" that display images, etc.

[0029] Of these, the image capturing device 10 is a digital camera for obtaining a wide-field image (such as a spherical image), as described above. The relay device 3 functions as a cradle for charging the image capturing device 10 and transmitting and receiving data. The relay device 3 can perform data communication with the image capturing device 10 via a contact point, and can also perform data communication with the communication control device 5 via the communication network 100. The communication network 100 includes, for example, the Internet, a LAN (Local Area Network), a (wireless) router, etc.

[0030] The communication control device 5 is, for example, a computer, and can perform data communication with the relay device 3 and the communication terminals 7 and 9 via the communication network 100. The communication control device 5 can also be referred to as an "information management device" because it manages information such as angle of view. The communication control device 5 may be configured by a single computer or by multiple computers.

[0031] The communication terminals 7 and 9 are, for example, computers such as smartphones and notebook PCs (Personal Computers), and can perform data communication with the communication control device 5 via the communication network 100. OpenGL ES is installed in the communication terminals 7 and 9, and the communication terminals 7 and 9 create a predetermined area image (see FIG. 6 ) from the omnidirectional image received from the communication control device 5.

[0032] Furthermore, the imaging device 10 and the relay device 3 are installed at predetermined positions by an organizer X or the like at a local site (site) Sa such as a construction site, exhibition hall, educational site, medical site, etc. The communication terminal 7 is operated by the organizer X. The communication terminal 9a is operated by a participant A such as a viewer who is in a remote location from the local site Sa. Similarly, the communication terminal 9b is operated by a participant B such as a viewer who is in a remote location from the local site Sa. Participant A and participant B may be in the same location or in different locations.

[0033] The communication control device 5 transmits (distributes) the wide-field image and audio data obtained from the image capturing device 10 via the relay device 3 to the communication terminals 7 and 9. The communication control device 5 also transmits (distributes) the captured image and audio data obtained from each of the communication terminals 7 and 9 to the communication terminals 7 and 9. Note that the captured image sent from the image capturing device 10 via the relay device 3 is a wide-field image, but if a single-lens reflex camera or the like is used instead of the image capturing device 10, the captured image will be a general narrow-field image. The captured image may be a video or a still image.

[0034] [Hardware configuration] Next, the hardware configurations of the image capturing device 10, relay device 3, and communication terminals 7 and 9 of this embodiment will be described in detail with reference to FIGS.

[0035] <Hardware configuration of the imaging device> Fig. 10 is a hardware configuration diagram of the photographing device 10. As shown in Fig. 10, the photographing device 10 is composed of an imaging unit 101, an image processing unit 104, an imaging control unit 105, a microphone 108, a sound processing unit 109, a CPU (Central Processing Unit) 111, a ROM (Read Only Memory) 112, an SRAM (Static Random Access Memory) 113, a DRAM (Dynamic Random Access Memory) 114, an operation unit 115, an input / output I / F 116, a short-range communication circuit 117, an antenna 117a of the short-range communication circuit 117, an electronic compass 118, a gyro sensor 119, an acceleration sensor 120, and a network I / F 121.

[0036] Of these, the imaging unit 101 is equipped with wide-angle lenses 102a and 102b (hereinafter referred to as lenses 102 when there is no need to distinguish between them) that are each capable of capturing an image with a field of view of 180° or more to form a hemispherical image, and two imaging elements 103a and 103b that are provided corresponding to the lenses 102a and 102b, respectively.

[0037] Furthermore, the imaging elements 103a, 103b include an image sensor such as a CMOS (Complementary Metal Oxide Semiconductor) sensor or a CCD (Charge Coupled Device) sensor that converts optical images captured by the lenses 102a, 102b, etc. into image data in the form of electrical signals and outputs the image data, a timing generation circuit that generates horizontal or vertical synchronization signals and pixel clocks for the image sensors, and a group of registers in which various commands or parameters required for the operation of the imaging elements are set. Note that the configuration in which the imaging unit 101 has two wide-angle lenses is merely an example, and the imaging unit 101 may have only one, or three or more.

[0038] The imaging elements 103a and 103b of the imaging unit 101 are each connected to the image processing unit 104 via a parallel I / F bus. On the other hand, the imaging elements 103a and 103b of the imaging unit 101 are each connected to the imaging control unit 105 via a serial I / F bus (such as an I2C bus).

[0039] The image processing unit 104, the imaging control unit 105, and the sound processing unit 109 are connected to a CPU 111 via a bus 110. Furthermore, the bus 110 is also connected to a ROM 112, an SRAM 113, a DRAM 114, an operation unit 115, an input / output I / F 116, a short-range communication circuit 117, an electronic compass 118, a gyro sensor 119, an acceleration sensor 120, a network I / F 121, and the like.

[0040] The image processing unit 104 takes in the image data output from the image sensors 103a and 103b via a parallel I / F bus, performs predetermined processing on each piece of image data, and then synthesizes the image data to create data for an equirectangular projection image (an example of a wide-field image), which will be described later.

[0041] The imaging control unit 105 generally sets commands and the like in the registers of the imaging elements 103a and 103b using an I2C bus, with the imaging control unit 105 acting as a master device and the imaging elements 103a and 103b acting as slave devices. Necessary commands and the like are received from the CPU 111. The imaging control unit 105 also uses the I2C bus to retrieve status data and the like from the registers of the imaging elements 103a and 103b and send it to the CPU 111.

[0042] Furthermore, the imaging control unit 105 instructs the imaging elements 103a and 103b to output image data when the shutter button on the operation unit 115 is pressed. Some imaging devices 10 have a preview display function or a function for displaying moving images on a display (for example, a display of an external terminal such as a smartphone that performs short-range communication with the imaging device 10 using the short-range communication circuit 117). In this case, the image data is output continuously from the imaging elements 103a and 103b at a predetermined frame rate (frames / minute).

[0043] As will be described later, the imaging control unit 105 also functions as a synchronization control means that cooperates with the CPU 111 to synchronize the output timing of image data from the imaging elements 103a and 103b. Although the imaging device 10 is not provided with a display unit in this embodiment, a display unit may be provided. The microphone 108 converts sound into sound (signal) data. The sound processing unit 109 receives the sound data output from the microphone 108 via an I / F bus and performs predetermined processing on the sound data.

[0044] The CPU 111 controls the overall operation of the image capturing device 10 and executes necessary processing. The ROM 112 stores various programs for the CPU 111. The SRAM 113 and DRAM 114 are work memories that store programs executed by the CPU 111, data in the middle of processing, etc. In particular, the DRAM 114 stores image data in the middle of processing by the image processing unit 104 and data of processed equirectangular projection images.

[0045] The operation unit 115 is a general term for various operation buttons, a power switch, a shutter button, a touch panel that combines display and operation functions, etc. A user operates the operation unit 115 to input various imaging modes, imaging conditions, etc.

[0046] The input / output I / F 116 is a general term for an interface circuit (such as a USB I / F) with an external medium such as an SD card or a personal computer. Communication via the input / output I / F 116 may be wireless or wired. The data of the equirectangular projection image stored in the DRAM 114 is recorded on an external medium via the input / output I / F 116, or transmitted to an external terminal (device) via the input / output I / F 116 as needed.

[0047] The short-range communication circuit 117 communicates with an external terminal (device) by short-range wireless communication technology such as NFC (Near Field Communication), Bluetooth (registered trademark), or Wi-Fi via an antenna 117a provided in the image capturing device 10. The short-range communication circuit 117 can transmit data of the equirectangular projection image to the external terminal (device).

[0048] The electronic compass 118 calculates the direction of the image capturing device 10 from the Earth's magnetism and outputs the direction information. This direction information is an example of related information (metadata) according to Exif, and is used for image processing such as image correction of the captured image. The related information also includes data such as the image capture date and time and the data size of the image data.

[0049] The gyro sensor 119 is a sensor that detects changes in angle (roll angle, pitch angle, yaw angle) that accompany the movement of the image capturing device 10. The changes in angle are an example of related information (metadata) according to Exif, and are used for image processing such as image correction of captured images.

[0050] The acceleration sensor 120 is a sensor that detects acceleration in three axial directions.

[0051] The photographing device 10 can also calculate the attitude (angle with respect to the direction of gravity) of the own device (the photographing device 10) by using the electronic compass 118, the acceleration sensor 120, etc. Furthermore, by providing the photographing device 10 with the acceleration sensor 120, the accuracy of image correction is improved.

[0052] The network I / F 121 is an interface for performing data communication using a communication network 100 such as the Internet via a router or the like. The hardware configuration of the image capturing device 10 is not limited to that shown here, and any hardware configuration may be used as long as it can realize the functional configuration of the image capturing device 10. At least a part of the hardware configuration may be present on the relay device 3 or the communication network 100.

[0053] <Hardware configuration of relay device> Fig. 11 is a diagram showing the hardware configuration of the relay device 3. Note that Fig. 11 shows the hardware configuration when the relay device 3 is a cradle having a wireless communication function.

[0054] As shown in FIG. 11, the relay device 3 includes a CPU 301, a ROM 302, a RAM 303, an EEPROM 304, a CMOS sensor 305, a bus line 310, a communication unit 313, an antenna 313a, a positioning unit 314, and an input / output I / F 316.

[0055] Of these, the CPU 301 controls the overall operation of the relay device 3. The ROM 302 stores programs such as an IPL (Initial Program Loader) used to drive the CPU 301. The RAM 303 is used as a work area for the CPU 301.

[0056] An EEPROM (Electrically Erasable and Programmable ROM) 304 reads or writes data under the control of the CPU 301. The EEPROM 304 stores an operating system (OS) executed by the CPU 301, other programs, and various data.

[0057] The CMOS (Complementary Metal Oxide Semiconductor) sensor 305 is a solid-state image sensor that captures an image of a subject under the control of the CPU 301 and obtains image data.

[0058] The communication unit 313 communicates with the communication network 100 by using a wireless communication signal via an antenna 313a.

[0059] The positioning unit 314 receives a positioning signal including the position information (latitude, longitude, and altitude) of the relay device 3 from a GNSS (Global Navigation Satellite System) satellite such as a GPS (Global Positioning Systems) satellite, or an IMES (Indoor Messaging System) as an indoor GPS.

[0089] (User / Device Management DB) Figure 14 is a conceptual diagram of a user device management table. The user device management DB 5001 is composed of the user device management table shown in Figure 14. In the user device table, user IDs (or device IDs), passwords, names, user images, and IP addresses are stored and managed in association with each other.

[0090] Among these, the user ID is an example of user identification information for identifying a user (organizer X, participants A, B, etc.). The device ID is an example of device identification information for identifying a device such as the image capturing device 10. Note that if a head-mounted display or the like is used in addition to the image capturing device 10, the head-mounted display or the like is also treated as a device.

[0093] The IP address is an example of destination identification information for devices such as the communication terminals 7 and 9 and the image capturing device 10 used by the user.

[0094] (Virtual room management DB) Fig. 15 is a conceptual diagram of a virtual room management table. The virtual room management DB 5002 is configured with the virtual room management table shown in Fig. 15. In the virtual room management table, the recording date, virtual room ID, virtual room name, device ID, organizer ID, participant ID, content ID, content URL (information on the storage location of content data of images and sounds), field of view information URL (information on the storage location of field of view information), and three-dimensional image ID are stored and managed in association with each other.

[0095] Of these, the video recording (audio recording) date indicates the date on which the process S36 described below was performed.

[0096] The virtual room ID is an example of virtual room identification information for identifying a virtual room.

[0097] The virtual room name is the name of the virtual room and is given by the user or the like.

[0098] The device ID is the same as the device ID in FIG. 14, and is the ID of the device that has participated in the virtual room indicated by the virtual room ID of the same record.

[0100] The participant ID is an example of participant identification information for identifying the participant ID among the user IDs in FIG. 14, and is the ID of a participant who has participated in the virtual room indicated by the virtual room ID of the same record.

[0101] The content ID is an example of content identification information for identifying image and sound content data. In this case, the image is a wide-field image obtained during shooting, and the sound is sound (including voice) obtained during the same shooting.

[0102] The content URL is an example of content storage location information that indicates the location where the content (wide-field image, sound information) data is saved (see process S54). The content URL also stores, in association with the content data, timestamps indicating the start and end dates and times of shooting (video recording) and sound collection (audio recording), and the shooting location (absolute location on Earth).

[0103] The field of view information URL is an example of field of view information storage location information that indicates the location where field of view information indicating the field of view of a specified area image displayed by a user (e.g., organizer X, participants A and B) during recording is saved (see processes S37 to S39).

[0104] The three-dimensional image ID is an example of three-dimensional image identification information that identifies a three-dimensional image to be displayed in a display area 620, which will be described later.

[0105] (3D image management DB) (Part 1) Fig. 16 is a conceptual diagram of a three-dimensional image management table (part 1). The three-dimensional image management DB 5003 is configured by the three-dimensional image management table shown in Fig. 16. In the three-dimensional image management table shown in Fig. 16, a model ID and position information are associated and managed for each three-dimensional image ID.

[0106] The model ID is an example of three-dimensional model identification information for identifying a three-dimensional model. The three-dimensional model is generated based on a point cloud acquired by, for example, a time-of-flight (TOF) camera.

[0107] The position information is information that indicates the position of the three-dimensional model in the three-dimensional virtual space using three-dimensional coordinates of XYZ, and is indicated, for example, by the three-dimensional coordinates of eight points that define the rectangular parallelepiped space occupied by the three-dimensional model.

[0108] (Part 2) Fig. 17 is a conceptual diagram of a three-dimensional image management table (part 2). The three-dimensional image management DB 5003 is configured by the three-dimensional image management table shown in Fig. 17. The three-dimensional image management table shown in Fig. 17 is a table for managing attribute information indicating the attributes of parts (three-dimensional models) that make up a structure included in a three-dimensional virtual space. In the three-dimensional image management table shown in Fig. 17, the attribute information, such as part number, member information, dimension information, color information, material information, position information, and construction date information, is managed in association with each three-dimensional image ID.

[0109] The component information is information that identifies components such as walls, floors, ceilings, windows, pipes, and doors that are made up of parts.

[0110] The dimension information is information that identifies the dimensions of a part in virtual space, and is expressed, for example, by numerical values ​​in the three axial directions of X, Y, and Z.

[0111] The color information is information for identifying the color of the part, and the material information is information for identifying the material of the part.

[0112] The position information is information for identifying the position of a part in virtual space, and is indicated by coordinates in three axes, X, Y, and Z, for example. This makes it possible to identify whether or not each of a plurality of parts is adjacent to another.

[0113] The construction date information indicates the planned date on which a component will be constructed in the real world, making it possible to identify a structure at a given point in time, excluding components that have not yet been constructed.

[0114] As described above, the position information in Figures 16 and 17 is managed in association with absolute positions on the Earth. As an example, by associating the origin (X=0, Y=0, Z=0) of the position information in Figures 16 and 17 with absolute positions on the Earth (latitude, longitude, altitude), all coordinates in the 3D images including the 3D model and parts can be associated with absolute positions on the Earth.

[0115] Furthermore, the three-dimensional image management DB 5003 may manage three-dimensional point groups, mesh objects, textured mesh objects, etc., instead of three-dimensional models.

[0116] (Movement history management DB) FIG. 18A is a conceptual diagram of a movement history management table that was created in the past. FIG. 18B is a conceptual diagram of a movement history management table that is currently being created. The movement history management DB 5004 is configured from the movement history management tables shown in FIGS. 18A and 18B. The movement history management DB 5004 is used in a fixed viewing content mode. The fixed viewing content mode is a mode in which the display content of the screens 600 and 601 displayed on all of the multiple communication terminals 7, 9a, and 9b in the same virtual room is made the same (common). In this case, the display content currently displayed on any one predetermined communication terminal (e.g., communication terminal 9a) among the multiple communication terminals 7, 9a, and 9b is fixed, and the same display content as this display content is also displayed on other communication terminals (e.g., communication terminals 7 and 9b).

[0117] In each movement history management table, the "filming and sound collection" date and time, filming location, angle of view information, and audio text are stored and managed in association with each other for each content ID. If sound is not collected, the filming date and time is shown. The position of the camera device 10 is determined by the positioning unit 314 of the relay device 3 to which the camera device 10 is attached. Note that the camera device 10 may be provided with a positioning unit similar to the positioning unit 314, and the position of the camera device 10 may be determined by this positioning unit. Here, since the movement history management tables in FIGS. 18A and 18B have the same data structure, only the movement history management table in FIG. 18A will be described, and a description of the movement history management table in FIG. 18B will be omitted.

[0118] The content ID shown in FIG. 18A is the same as the content ID shown in FIG.

[0119] The photographing and sound collection dates and times indicate the dates and times when the photographing device 10 photographed and collected the sound.

[0120] The image capturing position indicates the position (absolute position on the earth) when the image was captured by the image capturing device 10. When sound is collected, the image capturing position is also the sound collection position.

[0121] The field of view information is information for identifying a predetermined area indicating a predetermined area image displayed on a predetermined communication terminal (here, communication terminal 9a) among communication terminals 7, 9a, and 9b. For example, if a fixed viewing content mode (participant A's fixed viewing content mode) is set so that the screens 600 and 601 displayed and viewed by participant A on communication terminal 9a are also displayed on organizer X's communication terminal 7 and participant B's communication terminal 9b, the field of view information (including the user ID) received by the communication control device 5 in step S38 (described later) is managed not only as a field of view information URL managed in virtual room management DB 5002 (see FIG. 15) but also in movement history management DB 5004 (see FIG. 18B) according to the shooting and sound collection dates and times. In this case, communication terminals other than the fixed target (e.g., communication terminals 7 and 9b) do not transmit field of view information (e.g., steps S37 and S39 (described later)).

[0122] In the case of a viewing content fixed mode relating to the display content of the communication terminal 9a, the communication control device 5 not only stores the field of view information received in processes S37 to S39 described below in the field of view information URL managed in the virtual room management DB 5002 (see FIG. 15), but also manages the field of view information (the field of view information received in process S38) for identifying a specified area image included in the screens 600, 601 currently being displayed on the communication terminal 9a to be fixed in the movement history management DB 5004.

[0123] Furthermore, in the case of a viewing content fixed mode for the display content of communication terminal 9a, in order to cause communication terminals 7 and 9b to display a predetermined area image with the same display content as communication terminal 9a, the communication control device 5 transmits the field of view information (including the user ID of participant A) received in process S38 to communication terminal 7 in process S13 (to be described later) and also transmits it to communication terminal 9b in process S15. This allows communication terminal 7 (display control unit 74) and communication terminal 9a (display control unit 94) to display the same content as the predetermined area image currently being displayed on communication terminal 9a.

[0124] In addition, the fixed viewing content mode may be fixed to the screen displayed and viewed on the communication terminal 7 of the organizer X, and the same display content as that of the communication terminal 7 may be displayed on other communication terminals 9a and 9b, or may be fixed to the screen displayed and viewed on the communication terminal 9b of the organizer X, and the same display content as that of the communication terminal 9a may be displayed on other communication terminals 7 and 9a.

[0125] The voice text registered in the "voice text" column is text information converted from voice data recorded on the same record at the recording date and time.

[0126] When the voice text is generated by the text generator 56 from the current (streaming) voice, by pressing an "Audio Copy" button 683 (described later) (see FIG. 35), the processing unit 54 registers (copies) the past voice text currently displayed in the display area 635 in the "Audio Text" field in FIG. 18B. This past voice text is the voice text in the movement history management table (see FIG. 18A) identified by the content ID (e.g., c091) of another record (recorded on a past date) that has the same three-dimensional image ID (e.g., v001) associated with the content ID (e.g., c101) of the movement history management table (see FIG. 18B) currently being created in the virtual room management DB 5002 (see FIG. 15).

[0127] For example, when the "audio copy" button 683 shown in FIG. 35 is pressed, the audio text "Where is the new box?" in the movement history management table (see FIG. 18A), which is the source of the audio text "Where is the new box?" currently displayed in the display area 635, is copied to the "audio text" column in the movement history management table (see FIG. 18B) corresponding to the predetermined area image currently displayed in the display area 610 shown in FIG. 35. Note that in FIG. 18B, "(Where is the new box?)" is shown in parentheses to indicate that it has been copied later. Here, the audio text "Where is the new box?" is registered (copied) within the range in which the shooting position and angle of view information do not change in FIG. 18B (see S4). Note that the display area 635 is an example of a text display area.

[0128] In addition, when a speech text is already registered in the "Speech Text" field, the speech text can be copied by overwriting the already registered speech text or by adding it to the already registered speech text. When adding, the speech text is registered separately so that the already registered speech text and the newly copied speech text do not become mixed together and form a single sentence.

[0129] Conversely, by pressing an "audio copy" button 681 (described later), the current audio text generated by the current audio output together with the current predetermined area image being displayed in the display area 610 is registered (copied) in the "audio text" column of the movement history management table (see FIG. 18B) by the processing unit 54. This current audio text is the audio text in the movement history management table (see FIG. 18B) identified by the content ID (e.g., c101) of another (currently being recorded) record that has the same three-dimensional image ID (e.g., v001) associated with the content ID (e.g., c091) of the movement history management table (see FIG. 18A) created in the past in the virtual room management DB 5002 (see FIG. 15).

[0130] For example, when the "audio copy" button 681 shown in FIG. 35 is pressed, the audio text "Please reinforce the bottom of the box." in the movement history management table (see FIG. 18B), which is the source of the audio text being recorded "Please reinforce the bottom of the box," is copied to the "audio text" column in the movement history management table (see FIG. 18A) corresponding to the predetermined area image being displayed in the display area 630 shown in FIG. 35. Note that in FIG. 18A, "(Please reinforce the bottom of the box.)" is shown in parentheses to indicate that it was copied later. Here, in FIG. 18A, the audio text "Where is the new box?" is registered (copied) within the range where the shooting position and angle of view information do not change (see S3).

[0131] Furthermore, when voice text is already registered in the "voice text" field, if the voice text is to be duplicated, it is either overwritten or additionally duplicated as described above.

[0132] Furthermore, each movement history management table has a registration field for registering the display position of the icon of the virtual camera IC1 for each shooting and sound collection date and time. For example, by registering a flag in the registration field in the movement history management table (see FIG. 18A), the creation unit 53 can display an icon 622a or the like of the virtual camera IC1 at the shooting position in the display area 620 of a registered three-dimensional image in the past, as shown in FIG. 34. Similarly, for example, by registering a flag in the registration field in the movement history management table (see FIG. 18B), the creation unit 53 can display the icon of the virtual camera IC1 at the shooting position in the display area 620 of a registered three-dimensional image in the future, when the present is considered to be the past, as in the case shown in FIG. 34.

[0143] The reception unit 72 is mainly realized by processing from the CPU 501 to the operation unit 508, and receives instructions input by operation from a user (here, organizer X). The reception unit 72 also serves as an acquisition unit, and can be said to acquire instructions entered by user operation.

[0144] Creation unit 73 is mainly realized by processing of CPU 501, and creates a screen to be displayed on its own terminal (here, communication terminal 7) using data stored in storage unit 7000. Note that when creation unit 53 of communication control device 5 creates the screen, communication terminal 7 may or may not have creation unit 73.

[0145] The display control unit 74 is mainly realized by the processing of the CPU 501, and performs control to display various images on the display 507 of the communication terminal 7 or an external display connected to the external device connection I / F 505.

The sound input / output control unit 75 also performs control to collect sound from the microphone 513 and an external microphone connected to the external device connection I / F 505.

[0147] The connection unit 78 is mainly realized by processing from the CPU 501 to the external device connection I / F 505, and performs data communication with the connection unit 18 of the image capturing device 10 when the communication terminal 7 functions as a substitute for the relay device 3.

[0154] The creation unit 93 is mainly realized by the processing of the CPU 501, and creates a screen to be displayed on the terminal itself (communication terminal 9) using data stored in the storage unit 9000. When the creation unit 53 of the communication control device 5 creates the screen, the communication terminal 9 may or may not have the creation unit 73.

[0155] The display control unit 94 is mainly realized by the processing of the CPU 501, and performs control to display various images on the display 507 of the communication terminal 9 or an external display connected to the external device connection I / F 505.

[0156] The sound input / output control unit 95 is mainly realized by the processing of the CPU 501 of the communication terminal 9, and performs control to output sound to the speaker 512 of the communication terminal 9 or an external speaker connected to the external device connection I / F 505. In addition, the sound input / output control unit 75 performs control to collect sound from the microphone 513 and an external microphone connected to the external device connection I / F 505.

[0157] The connection unit 98 is mainly realized by processing from the CPU 501 to the external device connection I / F 505 of the communication terminal 7, and performs data communication with external devices connected by wire or wirelessly.

[0158] The storage / readout unit 99 is mainly realized by the processing of the CPU 501 , and stores various data (or information) in the storage unit 9000 and reads out various data (or information) from the storage unit 9000 .

[0159] [Processing or Operation of the Embodiment] Next, the processing or operation of the embodiment will be described with reference to Figures 19 to 35. Note that the following processing is performed after the image capturing device 10 and the communication terminals 7 and 9 have already joined the same virtual room.

[0160] <Communication processing of content data in a communication system> First, the communication processing of content data in the communication system 1 will be described with reference to FIG. 19. FIG. 19 is a sequence diagram showing the communication processing of content data in the communication system. In this embodiment, a case will be described in which the image capturing device 10, the communication terminal 7 of the organizer X, the communication terminal 9a of the participant A, and the communication terminal 9b of the participant B are in the same virtual room. Furthermore, when the virtual room is constructed, the storage / readout unit 79 adds one record to the virtual room management DB (see FIG. 15) and manages the virtual room ID, virtual room name, device ID, organizer ID, and participant ID in association with each other. The contents of the content ID, content URL, angle of view information URL, and three-dimensional image ID will be stored later. Note that the processes S11 to S15 in FIG. 19 are repeated, for example, 30 or 60 times per second.

[0161] S11: In the photographing device 10, the imaging unit 16 takes a 360-degree photograph of the local Sa and collects sound to obtain content (wide-field image, sound information) data, and then the connection unit 18 sends the content data to the relay device 3. In this case, the collected sound is mainly the voice of the organizer X of the local Sa. The connection unit 18 also sends a virtual room ID for identifying the virtual room in which the camera capture device 10 is participating and a device ID for identifying the camera capture device 10. Furthermore, the camera capture device 10 transmits information on the camera capture position, which is the position (absolute position) of the camera capture device 10, to the relay device 3 at predetermined time intervals (for example, every second). As a result, the connection unit 38 of the relay device 3 acquires the content data, the virtual room ID, the device ID, and the camera capture position information. The camera capture position is a position (absolute position on Earth) obtained from the positioning unit 314.

[0162] S12: In the relay device 3, the communication unit 31 transmits the content data, virtual room ID, device ID, and shooting position information acquired by the connection unit 38 in process S11 to the communication control device 5 via the communication network 100. As a result, in the communication control device 5, the communication unit 51 receives the content data, virtual room ID, device ID, and shooting position information.

[0163] Then, the storage / readout unit 59 of the communication control device 5 stores the content data received in process S12 in the virtual room management DB 5002 (see FIG. 15) for the content URL corresponding to the virtual room ID received in process S12.

[0164] The photographing device 10 may transmit the content data, the virtual room ID, the device ID, and the photographing position information to the communication terminal 7 instead of the relay device 3 (S11d). In this case, the communication terminal 7 transmits the content data, the virtual room ID, the device ID, and the photographing position information to the communication control device 5 (S12d).

[0165] S13: In the communication control device 5, the storage / readout unit 59 searches the virtual room management DB 5002 based on the virtual room ID received in step S12, thereby reading out the user IDs (organizer ID and participant ID) participating in the same virtual room as the image capturing device 10. The storage / readout unit 59 also searches the user / device management DB 5001 based on the readout organizer ID and participant ID, thereby reading out the corresponding user image of organizer X and the IP address of communication terminal 7, as well as the user images and communication terminals 9a and 9b of the corresponding participants A and B. The communication unit 51 then references the IP address of communication terminal 7 and performs two-way communication with communication terminal 7. The content of this two-way communication will be described later.

[0166] S14: The communication unit 51 of the communication control device 5 references the IP address of the communication terminal 9a and performs two-way communication with the communication terminal 9a. The content of this two-way communication will be described later.

[0167] S15: Similarly, the communication unit 51 of the communication control device 5 references the IP address of the communication terminal 9b and performs two-way communication with the communication terminal 9b. The content of this two-way communication will be described later.

[0168] <Process for starting video and audio recording in a communication system> Next, the process of starting video and audio recording in the communication system 1 will be described with reference to Fig. 20. Fig. 20 is a sequence diagram showing the process of starting video and audio recording in the communication system.

[0169] S31: First, in the communication terminal 7 of the organizer X, the reception unit 72 receives an operation from the organizer X to start video and audio recording.

[0170] S32: Before starting video and audio recording in the communication terminal 7, the communication unit 71 transmits a command to share the field of view information to the communication control device 5. This command includes the virtual room ID of the virtual room in which the communication terminal 7 is participating and the device ID of the image capturing device 10. As a result, the communication unit 51 of the communication control device 5 receives the command to share the field of view information.

[0171] S33: In the communication control device 5, the storage / readout unit 59 sets the content URL and the field of view information URL in the virtual room management DB (see FIG. 15). Then, the communication unit 51 transmits to the communication terminal 7 an instruction to start recording and a request to upload the field of view information. This instruction includes information indicating a content URL that indicates a location where the communication terminal 7 will save the content data after recording. This request also includes information indicating the field of view information URL for saving the field of view information. As a result, in the communication terminal 7, the communication unit 71 receives the instruction to start recording and the request to upload the field of view information.

[0172] S34: The communication unit 51 also transmits a request to upload the field of view information to the communication terminal 9a. This request includes information on the field of view information URL for saving the field of view information. As a result, the communication unit 91 of the communication terminal 9a receives the request to upload the field of view information.

[0173] S35: Similarly, the communication unit 51 transmits a request to upload the field of view information to the communication terminal 9b. This request includes information on the field of view information URL for saving the field of view information. As a result, the communication unit 91 of the communication terminal 9b receives the request to upload the field of view information.

[0174] S36: Next, in the communications terminal 7, the storage / readout unit 79 functions as a video recording unit and a sound recording unit, and starts recording and sound recording of the content data received in process S13 shown in Fig. 19. In the case of process S12d shown in Fig. 19, the communications terminal 7 may start recording and sound recording of the content data received from the imaging device 10 in process S11d, instead of the content data received from the communications control device 5 in process S13.

[0175] S37: In the communication terminal 7, for example, when the reception unit 72 receives a request from the organizer X to change the angle of view while the predetermined area image (see FIG. 6(b)) that is the predetermined area (see FIG. 6(a)) of the wide-field image received in process S13 is being displayed, the display control unit 74 displays a predetermined area image (see FIG. 6(d)) that is the predetermined area (see FIG. 6(c)) of the same wide-field image after the change. In this case, the reception unit 72 also serves as an acquisition unit, and when receiving a request from a user (here, organizer X) to display a predetermined area in the wide-field image, acquires angle of view information (pan, tilt, fov) for specifying the predetermined area to be displayed on the display 507 in the wide-field image.

[0176] Then, the communication unit 71 transmits the field of view information for identifying the changed predetermined area to the field of view information URL (communication control device 5) received in process S33. This field of view information includes the user ID of the organizer X of the communication terminal 7 that is the sender. As a result, the communication unit 51 of the communication control device 5 receives the field of view information.

[0177] Then, the storage / readout unit 79 stores the view angle information URL managed in the virtual room management DB (see FIG. 15) in association with the user ID and view angle information of the organizer X, as well as the date and time of reception of these. In this case, the reception date and time is managed as the date and time when the reception unit 72 of the communication terminal 7 received the change in view angle from the organizer X.

[0178] S38: The same process as S37 is performed independently of S37 in the communication terminal 9a and the communication control device 5. The user ID sent in this case is the user ID of participant A, and the reception date and time in this case is managed as the date and time when the reception unit 92 of the communication terminal 9a received the change in the angle of view from participant A.

[0179] S39: The same process as S37 is performed in the communication terminal 9b and the communication control device 5, independently of processes S37 and S38. Note that the user ID sent in this case is the user ID of participant B, and the reception date and time in this case is managed as the date and time when the reception unit 92 of the communication terminal 9b received the change in the angle of view from participant B.

[0180] As a result, when the predetermined area image is changed on the communication terminal 7 as shown in Fig. 6(b) to Fig. 6(d), the communication control device 5 can manage the predetermined area that the organizer X is paying attention to by viewing the predetermined area image shown in Fig. 6(d). Similarly, the communication control device 5 can manage the predetermined area that each participant A and B is paying attention to by viewing it on the communication terminals 9a and 9b. Note that steps S37 to S39 may be executed collectively on the communication control device 5 when recording ends.

[0181] On the other hand, in the case of the viewing content fixed mode, in the processes S37 to S39, only the predetermined communication terminal to be fixed (for example, communication terminal 9a) transmits the field angle information (including the user ID of participant A) to the communication control device 5.

[0182] <Processing for stopping video and audio recording in a communication system> Next, a process for stopping video and audio recording in the communication system 1 will be described with reference to Fig. 21. Fig. 21 is a sequence diagram showing a process for stopping video and audio recording in the communication system.

[0183] S51: First, in the communication terminal 7 of the organizer X, the reception unit 72 receives an operation from the organizer X to stop video and audio recording.

[0184] S52: The storage / readout unit 79 stops recording the content data.

[0185] S53: The communication unit 71 uploads (transmits) the video and audio content data to the specified content URL (communications control device 5) received in step S33. This content data includes the times (timestamps) from the start to the end of the video and audio recording. As a result, the communication unit 51 in the communications control device 5 receives the content data. The timestamps are the same as the shooting and audio collection dates and times shown in FIG. 18.

[0186] S54: In the communication control device 5, the storage / readout unit 59 stores the content data together with a timestamp in a predetermined content URL. Furthermore, the storage / readout unit 59 converts this timestamp (date and time of shooting and sound collection) into an elapsed playback time in accordance with the total recording time of the content data whose recording has been stopped, and manages the elapsed playback time in association with the timestamp.

[0187] S55: The communication unit 51 transmits a video and audio end notification to the communication terminal 7. The end notification includes information indicating a specific content URL. As a result, the communication unit 71 of the communication terminal 7 receives the video and audio end notification.

[0188] S56: Similarly, the communication unit 51 transmits a video and audio end notification to the communication terminal 9a. The end notification includes information indicating a specific content URL. As a result, the communication unit 91 of the communication terminal 9a receives the video and audio end notification.

[0189] S57: Similarly, the communication unit 51 transmits a video and audio end notification to the communication terminal 9b. The end notification includes information indicating a specific content URL. As a result, the communication unit 91 of the communication terminal 9b receives the video and audio end notification.

[0190] In the case of process S55, the completion notification does not need to include the predetermined content URL.

[0191] <Recording and playback of recorded data in a communication system> Next, the process of recording and playing back audio in a communication system will be described with reference to Fig. 22 to Fig. 28. Fig. 22 is a sequence diagram showing the process of recording and playing back audio in a communication system. Fig. 23 is a diagram showing a recorded data selection screen. Here, a case will be described in which participant A plays back recorded content data using communication terminal 9a, but organizer X may also play back content data using communication terminal 7, or participant B may play back content data using communication terminal 9b.

[0192] S71: First, when the reception unit 92 of the communication terminal 9a receives a login operation from participant A by inputting a user ID (participant A's participant ID), password, etc., the communication unit 91 transmits a login request to the communication control device 5. This request includes participant A's user ID and password. As a result, in the communication control device 5, the communication unit 51 receives the login request, and the authentication unit 55 performs authentication by referring to the user device management DB (see FIG. 14). Hereinafter, the explanation will proceed assuming that participant A is determined to be a legitimate accessing person through login authentication.

[0193] S72: In the communication control device 5, the creation unit 53 creates a recording data selection screen 940 as shown in FIG. 21. In this case, the storage / reading unit 59 searches the virtual room management DB (see FIG. 15) using the user ID (here, the participant ID of participant A) received in process S71 as a search key, thereby reading out all corresponding virtual room IDs, virtual room names, and content URLs. The creation unit 53 then creates each thumbnail 941, 942, 943 using an image from each piece of content data (with a timestamp) stored in the content URL. As a result, the creation unit 53 adds, for each thumbnail, a virtual room name (such as "Construction Site α") and a recording time (such as "2022 / 10 / 31 15:00") indicating a predetermined time in the timestamp (for example, the recording start time).

[0194] S73: The communication unit 51 transmits the selection screen data created in step S72 to the communication terminal 9a. In this selection screen data, each thumbnail includes a content ID for identifying the wide-field image from which each thumbnail was created. As a result, the communication unit 91 of the communication terminal 9a receives the selection screen data.

[0195] S74: In the communication terminal 9a, the display control unit 94 displays a recording data selection screen as shown in Fig. 23 on the display 507 of the communication terminal 9a. Then, the reception unit 92 receives a designation (selection) of a predetermined thumbnail from the participant A. Here, the description will continue assuming that the thumbnail 941 has been designated (selected).

[0196] S75: The communication unit 71 transmits to the communication control device 5 a download request for the content data that is the creation source of the selected thumbnail 941. This request includes the content ID associated with the thumbnail 941. As a result, the communication unit 51 of the communication control device 5 receives the download request for the content data.

[0197] S76: In the communication control device 5, the storage / reading unit 59 searches the virtual room management DB (see FIG. 15) using the content ID received in process S75 as a search key, and reads out content data from the corresponding content URL. The content data also includes location information at the time of image capture by the image capturing device 10. The storage / reading unit 59 also searches the three-dimensional image management DB (see FIG. 16 or 17) using the three-dimensional image ID associated with the content ID received in process S75 in the virtual room management DB as a search key, and reads out parameters of the corresponding model ID and location information (see FIG. 16A), or parameters of the corresponding part number, location information, etc. (see FIG. 16B).

[0198] Then, the communication unit 51 transmits the requested content data and the three-dimensional image data to the communication terminal 9a, whereby the communication unit 91 of the communication terminal 9a receives the content data and the three-dimensional image data.

[0199] S77: The communication terminal 9a performs a playback process. That is, the display control unit 94 of the communication terminal 9a displays a screen including the image recorded in process S36 on the display 507 of the communication terminal 9a, and the sound input / output control unit 95 outputs sound.

[0200] <Details of screen display process (registration)> 24 to 31, a process in a view content fixed mode in which the display of a predetermined communication terminal (here, communication terminal 9a) is fixed will be described. That is, of processes S13 to S15, process S14 will be described. Here, participant A operates communication terminal 9a, and the accepting unit 92 accepts the operation, and the communication unit 91 transmits operation information indicating the operation content to the communication control device 5. As a result, in the communication control device 5, the communication unit 51, which serves as an acquiring unit, acquires the operation information, and the creation unit 53 creates a screen 600 based on the operation content indicated by the operation information. Then, the communication unit 51 transmits data of the screen 600 to the communication terminal 9a, and the communication unit 91 of the communication terminal 9a receives the data of the screen 600, and the display control unit 94 displays the screen 600 on the display 507 or the like of the communication terminal 9a. In this case, the communication control device 5 is an example of an information processing device.

[0201] Alternatively, the communication unit 91 of the communication terminal 9a may receive each piece of data that is material for creating the screen 600 from the communication control device 5, and the reception unit 92, which functions as an acquisition unit, may acquire operation information indicating the content of the operation performed by the participant A. In this case, the creation unit 93 of the communication terminal 9a creates the screen 600. In this case, the communication terminal 9a is an example of an information processing device. The communication terminals 7 and 9b can also perform the same processes and functions as the communication terminal 9a.

[0202] Next, a process in which the communication control device 5 creates a screen 600 to be displayed on the display 507 of the communication terminal 9a will be described. In steps S13 and S15, the communication control device 5 performs the same process as step S14, except that the terminal on which the screen is displayed is different, and therefore a description of steps S13 and S15 will be omitted. Figures 24 and 25 are flowcharts showing the process executed by the communication control device in the screen display process.

[0203] First, the creation unit 53 of the communication control device 5 creates a screen 600 to be displayed by the communication terminal 9a, as shown in FIG. 26. FIG. 26 is a diagram showing an example of an initial display of a screen displayed on the communication terminal 9a. The screen 600 includes a display area 610 (a captured image display area, an example of a first captured image display area) and a display area 620 (an example of a three-dimensional image area). In FIG. 26, the display area 610 and the display area 620 are displayed simultaneously in the same size within the screen 600, but they may be displayed simultaneously in different sizes, or one of them may be displayed by switching selected by participant A. Alternatively, the display area 610 may be displayed on one of two displays of the screen 600, and the display area 620 may be displayed on the other.

[0204] The display area 610 displays a predetermined area image, which is a predetermined area in a wide-field image (an example of a captured image) obtained by photographing an object such as a desk, pillar, or window at the location Sa using the photographing device 10 (see Figures 6(a) and (b)).

[0205] Here, if the captured image is not a curved image such as a wide-field image, the display area 610 displays a predetermined area image whose predetermined area is the same area as the captured area of ​​the captured image.

[0206] The display area 620 displays a three-dimensional image including a three-dimensional model that represents the shape of the object in three dimensions and coordinates (an example of second coordinates) that correspond to coordinates (an example of first coordinates) that are positions in the wide-field image. In this case, the display area 620 displays a part or all of the three-dimensional image.

[0207] As explained in Figure 11, the shooting position, which is the position of the shooting device 10, is associated with an absolute position on Earth, and as explained in Figures 16 and 17, all coordinates in the three-dimensional images, including each three-dimensional model and part, managed in the three-dimensional image management DB 5003 are also associated with absolute positions on Earth.

[0208] As a result, as a process of aligning the wide-field image and the three-dimensional image, the processing unit 54 associates, for example, coordinates (an example of first coordinates) indicating the photographing position as a first position in the wide-field image of the content data received by the communication control device 5 in process S12 (or S12d) with coordinates (an example of second coordinates) indicating a second position in the three-dimensional image whose absolute position is the same as the coordinates. Here, coordinates are an example of position information.

[0209] As another form of alignment processing, the processing unit 54 may correspond coordinates indicating a first position in the wide-field image with coordinates indicating a second position in the three-dimensional image by image processing such as matching feature points such as edges or textures between the wide-field image and the three-dimensional image, without using absolute positions on the Earth (including indoors) or in order to complement the absolute positions.

[0210] Then, as described above, the creation unit 53 creates a screen 600 including a display area 610 that displays a predetermined area image, which is a predetermined area in the wide-field image, and a display area 620 that displays at least a portion of a three-dimensional image in which a second position (second coordinate) is associated with a first position (first coordinate) in the wide-field image by the processing unit 54.

[0211] Here, when the table of the three-dimensional image management DB 5003 manages a three-dimensional point cloud, a mesh object, or a textured mesh object, etc., instead of a three-dimensional model, the display area 620 displays at least a portion of a three-dimensional image including the three-dimensional point cloud, the mesh object, or the textured mesh object, etc., as a three-dimensional area corresponding to the object included in the wide-field image.

[0212] Also displayed on the screen 600 is a “Register” button 680. The “Register” button 680 is a button that is pressed when displaying, in the display area 620, an icon of the virtual camera IC1 whose shooting area is the angle of view (information) that specifies the predetermined area of ​​the predetermined area image being displayed in the display area 610, at a position corresponding to the shooting position of the image capturing device 10.

[0213] The screen 600 also displays a close button 609 that is pressed to close the screen 600.

[0214] Further, the display contents of the screen 600 will be described in detail below. The virtual camera IC1 is used to specify a predetermined area related to the predetermined area image to be displayed in the display area 610 (see FIG. 8), while the virtual camera IC2 described below is used to specify a three-dimensional image to be displayed in the display area 620.

[0215] S111: First, the creation unit 53 of the communication control device 5 identifies a predetermined area image to be displayed in the display area 610, as shown in FIG. 26, based on the field of view information (here, the virtual field of view of the virtual camera IC1 that is set in advance) from the wide-field image of the content data received by the communication unit 51.

[0216] S112: The processing unit 54 aligns the position of the virtual camera IC2 with the shooting position associated with the wide-field image obtained by shooting with the imaging device 10, and also aligns the virtual angle of view (an example of the second angle of view) of the virtual camera IC2 with the virtual angle of view (an example of the first angle of view) of the virtual camera IC1 that has been set in advance. As a result, the creation unit 53 creates a three-dimensional image to be displayed in the display area 620.

[0217] S113: The communication unit 51 determines whether a request to register the shooting date and time has been received from the communication unit 91 as a result of the "Register" button 680 being pressed with the cursor c1 or the like on the communication terminal 9a.

[0218] S114: If a registration request is acquired (S113; YES), the processing unit 54 registers the requested image capture date and time in the movement history management DB 5004 (see FIG. 18). In this case, the processing unit 54 registers (stores) a flag corresponding to the registration request in the registration field shown in FIG. 18. In this case, the date and time when the registration request is acquired is registered as the image capture and sound collection date and time.

[0219] As described in FIGS. 18A and 18B, in the movement history management DB 5004, the shooting and sound collection date and time, shooting position, angle of view information, and audio text are stored and managed in association with each content ID.

[0220] As described with reference to FIG. 15, the virtual room management DB 5002 stores and manages content IDs and content URLs (information on storage locations of content data of wide-field images and sound) in association with each other.

[0221] As a result, the shooting position, angle of view information, wide-field image, and sound (audio) text are associated with the registered shooting and sound collection date and time.

[0222] Here, the field of view information is information for identifying a specific area indicating the specific area image displayed on the communication terminal 9, so the shooting position, the specific area image, and the sound (audio) text are associated with the registered shooting and sound collection date and time.

[0223] S115: As shown in Fig. 27, the creation unit 53 superimposes an icon 622a of the virtual camera IC1 based on the shooting position and angle of view associated with the shooting and sound collection date and time registered in step S114 at a position corresponding to the shooting position in the display area 620. Fig. 27 is a diagram showing a screen on which the corresponding predetermined area, the icon of the virtual camera IC1, and a line diagram showing the line of sight of the virtual camera IC1 are displayed in the display area 620.

[0224] S116: Furthermore, the creation unit 53 superimposes a corresponding predetermined area 621a corresponding to the angle of view of the virtual camera IC1 in the display area 620, as shown in FIG. 27. FIG. 27 is a diagram showing a state in which an icon of the virtual camera IC11, a corresponding display area, and a line diagram indicating the line of sight are superimposed on the communication terminal 9a. This corresponding predetermined area 621a is an area corresponding to a predetermined area related to the predetermined area image displayed in the display area 610. Note that in FIG. 27, the corresponding predetermined area 621a is represented by a dashed line, but this is an example of a display mode of the corresponding predetermined area 621a. This display mode includes dashed lines and solid lines of a predetermined color, and the thickness of the dashed lines and solid lines may be different from that of other parts.

[0225] Furthermore, the creation unit 53 superimposes an icon 622a of the virtual camera IC1 at a position within the display area 620 that corresponds to the shooting position of the image capturing device 10, and superimposes the icon 622a so that it faces the center point CP1a of the corresponding predetermined area 621a. The icon 622a is an example of a schematic diagram (image) of the virtual camera IC1. In addition to the icon, this schematic diagram also includes characters such as "camera" or a figure including these characters.

[0226] Furthermore, the creation unit 53 superimposes a line diagram 623a indicating the line of sight from the icon 622a to the center point CP1a of the corresponding predetermined area 621a within the display area 620. This line diagram 623a may be a solid line or a dashed line, and may be displayed with a thickness or color different from that of the other lines.

[0227] 28 is a diagram showing a state in which a change has occurred in the object photographed on communication terminal 9a at the same photographing position and angle of view. As shown in Fig. 28, in display area 610 in which the currently photographed image is displayed, item M1, which was initially positioned on the left side and not displayed, is moved and is now displayed within display area 610.

[0228] 29 is a diagram showing another state in which the icon of the virtual camera IC1, the corresponding display area, and the line of sight diagram are superimposed on the communication terminal 9a. As shown in FIG. 29, when the shooting position of the image capturing device 10 changes, the content displayed in the display areas 610 and 620 also changes. Here, the corresponding predetermined area 621α, the icon 622α of the virtual camera IC1, and the line of sight diagram 623α of the virtual camera IC1 are shown.

[0229] S117: After process S116 or if a registration request has not been acquired in process S113 (NO), the creation unit 53 determines whether the position or angle of view of the virtual camera IC1 in the display area 610 has been changed (see FIG. 6(c)). For example, when participant A performs an operation to change the predetermined area image in the display area 610 shown in FIG. 27, the reception unit 92 receives the changed angle of view, and the communication unit 91 transmits angle of view information indicating the changed angle of view to the communication control device 5. As a result, when the communication unit 51 receives the angle of view information indicating the changed angle of view, the creation unit 53 determines that the angle of view of the virtual camera IC1 has been changed. Then, when the position or angle of view of the virtual camera IC1 has been changed (S117; YES), the process returns to process S111. In this way, by repeating processes S111 to S116, each time the "Register" button 680 is pressed at different times, the communication unit 51 acquires multiple registration requests, and the processing unit 54 registers flags corresponding to the multiple registration requests in the movement history management DB 5004. Furthermore, as shown in Fig. 30, the creation unit 53 superimposes multiple virtual camera IC1 icons 622c, 622b, 622a, etc. in the display area 620, and also superimposes movement path images Rcb, Rba indicating the movement path of the image capturing device 10.

[0230] 30 is a diagram showing the movement path of the icon of each virtual camera IC1, which indicates the position and angle of view of the image capturing device at the time of registering the image capturing date and time, and a diagram showing the latest corresponding display area and line of sight, superimposed on the icon. In FIG. 30, icon 622b is superimposed when the "Register" button 680 is pressed immediately before icon 622a, and icon 622c is superimposed when the "Register" button 680 is pressed immediately before icon 622b.

[0231] In addition, when the shooting positions of the multiple virtual cameras IC1 are the same, the creation unit 53 may superimpose an icon 622 of one virtual camera IC1 in the display area 620, and may also superimpose a list of multiple shooting dates and times in association with this icon 622 of the one virtual camera IC1.

[0232] S118: If the reception unit 92 receives a request to end the display of the screen 600 by, for example, pressing the close button 609 by participant A (YES), the display of the screen 600 ends. On the other hand, if the reception unit 92 does not receive a request to end the display of the screen 600 (NO), the process returns to step S117, and the processes in FIGS. 24 and 25 continue until the transmission of the captured image data by the communication control device 5 is completed in step S14 shown in FIG.

[0233] <Registration Variations> In the above example, a predetermined area image of the currently captured image is displayed, but this is not limited to this. For example, as shown in Fig. 31, multiple predetermined area images of the same captured image that have already been recorded but with different capture dates and times may be displayed. Fig. 31 is a diagram showing a screen when multiple recorded predetermined area images are played back on the communication terminal 9a.

[0234] In this case, the creation unit 53 creates a screen 600 including a display area 610a that displays a first predetermined area image, which is a predetermined area at a first photographing date and time in a photographed image aligned with an undisplayed three-dimensional image, and a display area 610b that displays a second predetermined area image, which is a predetermined area at a second photographing date and time in the same photographed image. In FIG. 31, the predetermined area image displayed in the display area 610b was photographed later than the predetermined area image displayed in the display area 610a. Therefore, it can be seen that the position of the item M11 has been moved, as shown in the display area 610b.

[0235] In addition, in FIG. 31, display areas 650a and 650b are displayed below the display areas 610a and 610b, respectively.

[0236] Display area 650a displays audio text based on audio within a predetermined time period including the elapsed playback time of the image being displayed in display area 610a. For example, in Fig. 18A, when the shooting and sound collection date and time (elapsed playback time) is "2023 / 11 / 11 10:00:08", creation unit 53 creates screen 600 to be displayed in display area 650a using audio text "Please reinforce the bottom of the pillar." that was registered during the period when the shooting position and angle of view information did not change (2023 / 11 / 11 10:00:07 to 2023 / 11 / 11 10:00:09).

[0237] Similarly, display area 650b displays audio text based on audio within a predetermined time period including the elapsed playback time of the image being displayed in display area 610b. For example, in Fig. 18B, when the shooting and sound collection date and time (elapsed playback time) is "2023 / 12 / 11 10:00:08", creation unit 53 creates screen 600 to be displayed in display area 650b using audio text "The new box has been moved to the left." that was registered during the period when the shooting position and angle of view information did not change (2023 / 12 / 11 10:00:07 to 2023 / 12 / 11 10:00:09).

[0238] In addition, "Register" buttons 680a and 680b are displayed below each of the display areas 610a and 610b. The "Register" buttons 680a and 680b function in the same manner as the "Register" button 680.

[0239] Furthermore, when the communication unit 51 receives a registration request to superimpose an icon of a virtual camera IC1 whose shooting area is the angle of view during display of a first specified area image at a first shooting position at a first shooting date and time, or an icon of a virtual camera whose shooting area is the angle of view during display of a second specified area image at a second shooting position at a second shooting date and time, within the three-dimensional image display area that displays at least a part of the three-dimensional image, the processing unit 54 registers a flag corresponding to the registration request in the registration column of the movement history management DB 5004 (see Figures 18A and B).

[0240] <Details of screen display process (after registration)> Next, referring to FIGS. 32 to 35, a process in a viewing content fixed mode in which the display of a predetermined communication terminal (here, communication terminal 9a) is fixed will be described. That is, among processes S13 to S15, process S14, which is a screen display process after registration, will be described. Note that in FIGS. 34 and 35, components with the same reference numerals as those in FIGS. 26 to 32 have the same roles or functions. Here, when participant A operates communication terminal 9a, the accepting unit 92 accepts the operation, and the communication unit 91 transmits operation information indicating the operation content to the communication control device 5. As a result, in the communication control device 5, the communication unit 51, which serves as an acquiring unit, acquires the operation information, and the creation unit 53 creates a screen 601 based on the operation content indicated by the operation information. Then, when the communication unit 51 transmits data of the screen 601 to the communication terminal 9a, the communication unit 91 of the communication terminal 9a receives the data of the screen 601, and the display control unit 94 displays the screen 601 on the display 507 or the like of the communication terminal 9a. In this case, the communication control device 5 is an example of an information processing device.

[0241] Next, a process in which the communication control device 5 creates a screen 601 to be displayed on the display 507 of the communication terminal 9a will be described. Note that in steps S13 and S15, the communication control device 5 performs the same process as step S14, and only the terminal on which the display is performed is different, so a description of steps S13 and S15 will be omitted. Figures 32 to 33 are flowcharts showing the process executed by the communication control device in the screen display process after the photography date and time is registered.

[0242] First, the creation unit 53 of the communication control device 5 creates a screen 601 to be displayed by the communication terminal 9a, as shown in FIG. 34. FIG. 34 is a diagram showing a screen displayed on the communication terminal 9a when a current predetermined area image is displayed after the image capture date and time has been registered. The screen 601 includes a display area 610 (a captured image display area; an example of a first captured image display area), a display area 620 (an example of a three-dimensional image area), and a display area 630 (an example of a second captured image display area). In FIG. 34, the display areas 610, 620, and 630 are displayed simultaneously in the same size within the screen 601. However, they may be displayed simultaneously in different sizes, or one of them may be displayed by switching selection by participant A. Alternatively, the display areas 610, 620, and 630 may be displayed on each of the three displays of the screen 601.

[0243] The display area 610 displays a predetermined area image, which is a predetermined area in the current wide-field image (an example of the current captured image) obtained by capturing an image of an object using the imaging device 10 (see Figures 6(a) and (b)).

[0244] The display area 620 includes a three-dimensional model that represents the shape of an object (such as a table or pillar) in three dimensions, and displays part or all of a three-dimensional image in which coordinates (an example of second coordinates) are associated with coordinates (an example of first coordinates) in the wide-field image.

[0245] The display area 630 displays a predetermined area image, which is a predetermined area in a past wide-field image (an example of a past captured image) obtained by capturing an object using the imaging device 10 (see Figures 6(a) and (b)).

[0246] Here, if the captured image is not a curved image such as a wide-field image, the display areas 610 and 630 display a predetermined area image whose predetermined area is the same as the captured area of ​​the captured image.

[0247] .

[0248] Also here, as described above, processing unit 54 aligns display areas 610, 620, and 630. Then, as described above, creation unit 53 creates screen 601 including display area 610 displaying a predetermined area image that is a predetermined area in the current wide-field-of-view image, display area 620 displaying at least a part of a three-dimensional image in which a second position (second coordinates) is associated with a first position (first coordinates) in the wide-field-of-view image, and display area 630 displaying a predetermined area image that is a predetermined area in the past wide-field-of-view image in which a third position (third coordinates) is associated with the first position (first coordinates).

[0249] Also displayed on the screen 601 is a "Register" button 680. The "Register" button 680 fulfills the same role or function as the "Register" button 680 shown in FIG.

[0250] Further, the display contents of the screen 601 will be described in detail below. Note that the virtual camera IC1 is used to identify a predetermined area related to each predetermined area image to be displayed in the display areas 610 and 630 (see FIG. 8), while the virtual camera IC2 is used to identify a three-dimensional image to be displayed in the display area 620.

[0251] S211: First, the creation unit 53 of the communication control device 5 identifies the current specified area image to be displayed in the display area 610, as shown in FIG. 34, based on the field of view information (here, the virtual field of view of the virtual camera IC1 that is set in advance) from the wide-field image of the content data received by the communication unit 51.

[0252] S212: The processing unit 54 aligns the position of the virtual camera IC2 with the shooting position associated with the wide-field image (content data) obtained by shooting with the imaging device 10, and also aligns the virtual angle of view (an example of the second angle of view) of the virtual camera IC2 with the virtual angle of view (an example of the first angle of view) of the virtual camera IC1 that has been set in advance. As a result, the creation unit 53 creates a three-dimensional image to be displayed in the display area 620.

[0253] 34, pressing a "Register" button 680 performs the same processes as steps S113 to S116 described above. This enables creation unit 53 to superimpose corresponding predetermined area 621A and diagram 623A indicating the line of sight of icon 622A (an example of an image indicating a first virtual camera) of virtual camera IC1 relative to center point CP1A of corresponding predetermined area 621A in display area 620 at a position corresponding to the current shooting position.

[0254] S213: Furthermore, as shown in Fig. 34, the creation unit 53 superimposes icons 622a to 622c (images of past photographing positions, examples of images indicating the second virtual camera) of the virtual camera IC1 based on the photographing positions and angles of view associated with the registered photographing dates and times in the display area 620. When there are multiple icons like this, the creation unit 53 also superimposes travel path images Rba and Rcb.

[0255] In addition, when the shooting positions of the multiple virtual cameras IC1 are the same, the creation unit 53 superimposes an icon 622 of one virtual camera IC1 in the display area 620, and also superimposes a list of multiple shooting dates and times in association with the icon 622 of this one virtual camera IC1.

[0256] S214: The creation unit 53 determines whether there is an icon of the virtual camera IC1 relating to a past photographing position within a predetermined range from the current photographing position. The predetermined range is, for example, 3 m when an absolute position is assumed.

[0257] S215: If there is an icon of virtual camera IC1 relating to a past shooting position within a predetermined range from the current shooting position (S214: YES), the creation unit 53 identifies a predetermined icon at a past shooting position that is closest to the current shooting position (the position of the icon 622A of virtual camera IC1) within the predetermined range from among the icons 622a, 622b, and 622c of past virtual camera IC1 at multiple positions. Here, the icon 622a is identified.

[0258] S216: On the other hand, if there is no icon of the virtual camera IC1 relating to the past shooting position within a predetermined range from the current shooting position (S214: NO), the communication unit 51 determines whether or not an instruction to select (or specify) a specific past virtual camera IC1 icon from among the multiple past virtual camera IC1 icons has been acquired by the participant A. If the communication unit 51 does not acquire a selection (S216; NO), the communication unit 51 repeats the determination of whether or not to acquire this selection.

[0259] As explained in process S213, when the creation unit 53 superimposes a list of multiple shooting dates and times in association with the icon 622 of one virtual camera IC1 in the display area 620, the communication unit 51 determines whether it has received an instruction from participant A to select (or specify) a specific past shooting date and time from among the multiple past shooting dates and times.

[0260] S217: After process S215 or when a selection is acquired in process S216 (S216; YES), the creation unit 53 changes the display form of the icon (icon 622a in this case) of a past predetermined virtual camera IC1, as shown in FIG. 35. FIG. 35 is a diagram showing a screen in the case where a past predetermined area image is additionally displayed after the photographing date and time is registered in the communication terminal 9a. The change in the display form is, for example, a change in the shape, pattern, color, etc. of the icon. Furthermore, the creation unit 53 displays the icon 622a on top of the icon 622A, as shown in FIG. 35. Note that in FIGS. 34 and 35, when the creation unit 53 superimposes the icon 622a at the past photographing position and the icon 622A at the current photographing position at exactly the same position, the size of either icon may be changed or the superimposition may be slightly shifted.

[0261] S218: As in process S116, the creation unit 53 superimposes in the display area 620 a corresponding predetermined area 621a relating to the icon of a past predetermined virtual camera IC1 and a line diagram 623a showing the line of sight of the icon 622a of the virtual camera IC1 relative to the center point CP1a of this corresponding predetermined area 621a.

[0262] S219: Then, as shown in FIG. 35, the creation unit 53 adds a display area 630 (an example of a second captured image display area) that displays a past predetermined area image (an example of a second predetermined area image) corresponding to the icon 622a of the virtual camera IC1 to the screen 601. Furthermore, the creation unit 53 adds a display area 635 that displays voice text (text information) generated from a voice recorded when the past predetermined area image to be displayed was captured to the screen 601. In this case, as shown in FIG. 18A, the creation unit 53 creates the screen 601 for displaying, in the display area 635, voice text for each of the times (periods) S1 to S3 during which neither the capturing position nor the angle of view of the predetermined area image to be displayed in the display area 630 has changed. That is, the past predetermined area image displayed in the display area 630 is a part of a captured image at a certain point in the past (for example, a predetermined one second), but the past voice text displayed in the display area 635 may be content uttered over several seconds (see S1 in FIG. 18).

[0263] Furthermore, the creation unit 53 includes the above-mentioned "Register" button 680 on the screen 601, as well as new "Audio Copy" buttons 681 and 683. The "Audio Copy" button 681 is a button for copying the current audio text output together with the current predetermined area image displayed in the display area 610, in association with the past predetermined area image displayed in the display area 630. The "Audio Copy" button 683 is a button for copying the past audio text output together with the past predetermined area image displayed in the display area 630, in association with the current predetermined area image displayed in the display area 610.

[0264] S220: When the "Audio Copy" button 683 is pressed, the processing unit 54 determines via the acquisition unit (reception unit 92, communication unit 51) whether there is an instruction to associate past audio text with the current specified area image and copy it.

[0265] S221: If there is an instruction to copy (S220; YES), the processing unit 54 associates the past voice text (text information) being displayed in the display area 635 with the shooting and sound collection date and time of the current predetermined area image (predetermined area) being displayed in the display area 610, and registers (copies) it in the "voice text" field of the movement history management DB 5004 (see FIG. 18B). As a result, when the current predetermined area image is displayed later, the voice text copied in the movement history management DB (FIG. 18B) (e.g., "Where is the new box?") and the voice text registered in the movement history management DB (FIG. 18B) (e.g., "The new box has been moved to the left") are displayed consecutively, making it easier for participant A to grasp the differences between the past and present not only from the predetermined area image but also from the voice text.

[0266] S222: After process S221, or if there is no instruction to duplicate in process S220 (S220; NO), the processing unit 54 determines whether there is an instruction to duplicate the audio text generated from the current audio by associating it with a past specified area image via the acquisition unit (reception unit 92, communication unit 51) when the "audio duplication" button 681 is pressed.

[0267] S223: If there is an instruction to copy the current voice to the past (S222; YES), the processing unit 54 associates the current voice text (text information) generated by the text generation unit 56 from the current voice data (content data) being output with the shooting and sound collection date and time of the past predetermined area image (predetermined area) displayed in the display area 630, and registers it in the "voice text" field of the movement history management DB 5004 (see FIG. 18A). As a result, when the past predetermined area image is redisplayed later, based on the recording time of the past predetermined area image, the voice text generated from the voice at the time of current shooting and sound recording (e.g., "The new box has been moved to the left" and "The new box is scheduled to be moved to the left") and the voice text at the time of sound recording (e.g., "Please reinforce the bottom of the pillar") are displayed consecutively, making it easier for participant A to grasp the differences between the time of sound recording and the future sound recording not only from the predetermined area image but also from the voice text.

[0268] The order of steps S220 and S221 and steps S222 and S223 may be reversed.

[0269] S224: After process S223, or if there is no instruction to copy in process S223 (S222; NO), if the reception unit 92 receives a request to end the display of the screen 601 by participant A pressing the close button 609, etc. (YES), the creation unit 53 ends the display of the screen 601. On the other hand, if the reception unit 92 does not receive a request to end the display of the screen 601 (NO), the process returns to process S214, and the processes of FIGS. 32 and 33 continue until the communication control device 5 finishes transmitting the captured image data in process S14 shown in FIG. 19.

[0270] [Major Effects of the Embodiments] As described above, according to this embodiment, the processing unit 54 associates a first position in the captured image obtained by photographing the object with a second position in the three-dimensional image including a three-dimensional area corresponding to the object, and the creation unit 53 (or creation unit 73, 93) creates a screen 600 including a display area 610 that displays a predetermined area image, which is a predetermined area in the captured image obtained by photographing the object, and a display area 620 that displays at least a part of the three-dimensional image in which the second position is associated with the first position in the captured image by the processing unit 54.

[0271] This allows a user (e.g., participant A) to understand where and what the predetermined area image is taken of by viewing screen 600. Furthermore, even if the user is unable to photograph the back side of an object, the user can understand the state of the back side of the object by viewing screen 600. Therefore, by creating an image that complements the photographed image, it is possible to achieve the effect of improving user convenience.

[0272] Furthermore, by associating the photographing date and time (and audio collection date and time), photographing location, angle of view currently being displayed, and audio text using the movement history management DB 5004 shown in Figures 18A and 18B, when participant A presses the "Register" button 680 while a specified area image is being displayed in the display area 610, the processing unit 54 can register the photographing and audio collection date and time, photographing location, angle of view, and audio text currently being displayed in the movement history management DB 5004 (by registering a flag in the registration field).

[0273] Furthermore, as shown in FIG. 27, the creation unit 53 can superimpose an icon 622a or the like of a virtual camera IC1 whose shooting area is the angle of view currently being displayed of the specified area image at a position corresponding to the shooting position within the display area 620.

[0274] 34, the creation unit 53 can display an icon 622a of the virtual camera IC1 at a previously registered shooting position in the display area 620. Then, when the participant A or the like presses the icon 622a, the creation unit 53 creates a screen 601 in the display area 630 to display, as shown in FIG. 35, an image captured at the shooting date and time corresponding to the icon 622a, a predetermined area image indicating the angle of view corresponding to the icon 622a, and audio text at this shooting date and time. This allows the participant A or the like to identify the shooting date and time and angle of view of the previously captured image with reference to the position of the icon of the virtual camera IC1, thereby detecting the predetermined area image at a desired shooting time from among the previously captured images.

[0275] 〔supplement〕 Although the embodiments have been described above, the present invention is not limited to these embodiments, and various modifications and substitutions can be made without departing from the scope of the present invention.

[0276] (1) Each function of each of the above embodiments can be realized by one or more processing circuits. Here, the term "processing circuit" in this specification includes a processor programmed to execute each function by software, such as a processor implemented by an electronic circuit, as well as devices such as an ASIC (Application Specific Integrated Circuit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), and conventional circuit modules designed to execute each of the above-described functions.

[0277] (2) A (non-transitory) recording medium such as a DVD-ROM on which each of the above programs is stored can be provided domestically or internationally as a program product.

[0278] (3) There may be multiple CPUs 111, 301, and 501 as processors that are hardware.

[0279] (4) In the above embodiment, in Fig. 18, the voice text generated by the text generation unit 56 is registered, but this is not limited to this. For example, without using the text generation unit 56, the reception unit 92 may receive text entered by a user (e.g., participant A), and the text data may be transmitted to the communication unit 51 of the communication control device 5 via the communication unit 91, and the processing unit 54 may register the text in the movement history management DB 5004. The record registered here is a record of the same shooting and voice collection date and time as the date and time the communication unit 51 received the text data. [Explanation of symbols]
