Description

[Technical Field]

[0001] The present invention relates to a stereoscopic image display system that can be used by companies and the like when developing various products. [Background technology]

[0002] For example, the cable movement range display device disclosed in Patent Document 1 includes a real space information acquisition unit that acquires real space information related to real space; a user position and posture estimation unit that determines the position and posture of the user from the real space information; a simulation unit that receives wiring route information indicating the start point, pass points, and end point of the wiring route and cable information indicating the allowable bending radius of the cable and the length of the cable, and calculates the cable movement range from the wiring route information and the cable information; an image generation unit that generates a virtual reality cable movement range image that indicates the cable movement range in real space from the cable movement range calculated by the simulation unit and the position and posture determined by the user position and posture estimation unit; and an image display unit that displays the virtual reality cable movement range image.

[0003] Furthermore, a collaborative virtual reality online conference platform disclosed in Patent Document 2 replaces an on-site conference with a conference in a common virtual space in virtual reality (VR). The platform includes three-dimensional (3D) point cloud data defining the virtual space, identifiers of multiple conference participants, and conference data including the positions in the virtual space of multiple avatars corresponding to the conference participants. The platform also includes a processor that executes instructions to start an online conference of the multiple conference participants. The step of starting the online conference also includes the steps of providing each conference participant with an address of the 3D point cloud and transmitting the 3D point cloud data and conference data to each conference participant. The current location of each avatar in the virtual space is communicated to all conference participants. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2018 / 020568 [Patent Document 2] Japanese Patent Application Publication No. 2019-82997 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, when a company or the like develops various products, there are cases where multiple people in charge from multiple locations of the same company or affiliated companies gather at the same place at the same time to conduct discussions about a specific product.

[0006] For example, when developing a new wire harness product to be installed in a vehicle or changing the specifications of an existing product, representatives from the relevant department of the vehicle manufacturer, the design department of the parts company that manufactures the wire harness, the domestic manufacturing departments of the parts company, and the parts company's overseas manufacturing plants all gather in the same place, and the representatives from each department exchange opinions from their respective positions, discuss, and decide on appropriate specifications.

[0007] Specifically, when determining the wiring route, shape, and layout of jigs used in manufacturing a wire harness, vehicle manufacturers must consider factors such as ease of assembly of the wire harness into the vehicle. Also, design personnel at parts manufacturers must consider factors such as component costs and manufacturing costs. Also, manufacturing personnel at parts manufacturers must consider factors such as ease of manufacturing the wire harness.

[0008] For example, parts manufacturers that produce wire harness products generally use a flat jig plate to manufacture wire harnesses. That is, a number of jigs that determine the reference positions of each part of the wiring path are arranged on the jig plate, and workers or the like sequentially arrange or stack a number of parts such as electric wires on this jig plate so that they pass through a predetermined wiring path along each jig, thereby assembling the wire harness, which is a three-dimensional structure. Therefore, the external shape of the wire harness manufactured by parts manufacturers basically has a three-dimensional structure with relatively little change in shape or undulation in the vertical direction.

[0009] On the other hand, the vehicle body on which the wire harness is mounted has a very complex three-dimensional structure, and the positions at which each of the numerous electrical components mounted on the vehicle body is disposed are also individually determined as needed within the three-dimensional space on the vehicle body. Therefore, the external shape of the wire harness that is actually installed and routed on the vehicle has a three-dimensional structure with many ups and downs that changes significantly in the vertical direction so that the numerous electrical components on the vehicle can be connected to each other.

[0010] In other words, the three-dimensional shape of a wire harness manufactured by a parts manufacturer generally differs greatly from the three-dimensional shape of a wire harness actually assembled in a vehicle. Therefore, for example, a discrepancy may occur between the three-dimensional structure of a wire harness understood by a designer at a parts manufacturer and the three-dimensional structure of a wire harness understood by a designer at a vehicle manufacturer.

[0011] For example, if the design specifications presented by the vehicle manufacturer's designers are such that problems will occur during the manufacturing of the wire harness, then the design specifications will need to be reconsidered in order to be changed.Also, if the design specifications presented by the wire harness parts manufacturer are such that problems will occur during the assembly of the wire harness into the vehicle, then the design specifications will need to be reconsidered in order to be changed.

[0012] When people in charge of multiple independent locations conduct their own studies in different locations as described above, differences of opinion tend to arise between the locations, leading to repeated specification changes, etc. In particular, when people in charge of each location conduct their own studies while looking at the contents of a two-dimensional drawing, it is difficult to grasp the actual three-dimensional shape of each part of the wire harness, making it difficult to find problem areas.

[0013] Therefore, in many cases, people from multiple locations gather in the same place at the same time and conduct simultaneous reviews while looking at an actual model of the wire harness and actual jigs placed on a single work table. This reduces the number of times changes are made to the wire harness manufacturing specifications, improving development efficiency.

[0014] For example, when the technology of Patent Document 1 is adopted, it is possible to display the cable movement range of the cable being laid out in a superimposed manner on the real space. However, it is not possible to display information that satisfies both the specifications such as the three-dimensional shape required by the parts manufacturer of the wire harness for manufacturing and the specifications such as the three-dimensional shape when the wire harness is actually assembled to the vehicle body.

[0015] Furthermore, if a VR system like that in Patent Document 2 is adopted, it is possible for personnel from various locations to simultaneously grasp the three-dimensional shape of the same product on different computer screens, without the need for them to travel and gather in one location. However, it is not possible to display information that satisfies both the specifications, such as the three-dimensional shape, required by the wire harness component manufacturer for manufacturing and the specifications, such as the three-dimensional shape, required when the wire harness is actually assembled to a vehicle body. Furthermore, it is not possible to make changes to product specifications, etc., reflecting the opinions of each personnel in the middle of a meeting, and it is not possible to see the results of the changes. As a result, meetings must be held multiple times each time a change is needed, making meetings inefficient.

[0016] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a three-dimensional image display system that is useful for understanding at least the three-dimensional shape under both conditions, that is, the specifications under which the wire harness is manufactured and the specifications under which the wire harness is assembled to a vehicle. [Means for solving the problem]

[0017] The above object of the present invention can be achieved by the following configuration.

[0018] a three-dimensional image generating device that generates three-dimensional image data of the wire harness based on design data of the wire harness; a projection unit that acquires the stereoscopic image data from the stereoscopic image generating device and projects a stereoscopic image based on the stereoscopic image data into a VR space that can be recognized by a user; The three-dimensional image data includes first three-dimensional image data representing the wire harness in a state where it is laid out on a jig plate, and second three-dimensional image data representing the wire harness in a state where it is assembled to a vehicle. Including, The projection unit projects a first stereoscopic image based on the first stereoscopic image data and a second stereoscopic image based on the second stereoscopic image data by aligning the images so that the images are adjacent to each other. death , the projection unit projects the first stereoscopic image and the second stereoscopic image by aligning a first reference plane in the first stereoscopic image and a second reference plane in the second stereoscopic image so that they are aligned parallel to each other and spaced apart by at least a certain distance in the vertical direction; Stereoscopic image display system. [Effects of the Invention]

[0019] According to the stereoscopic image display system of the present invention, the user can easily grasp the three-dimensional shape and the like of both the specifications of the wire harness at the time of manufacture and the specifications of the wire harness at the time of vehicle assembly from the displayed content. That is, the first stereoscopic image and the second stereoscopic image are simultaneously displayed in a state where they are aligned in the stereoscopic image projected by the projection unit, so that the user can simultaneously grasp the three-dimensional shape of the wire harness at the time of manufacture and the three-dimensional shape of the wire harness at the time of vehicle assembly in a state where they can be compared.

[0020] The present invention has been briefly described above. The details of the present invention will become clearer by reading the following detailed description of the invention (hereinafter referred to as "embodiments") with reference to the accompanying drawings.

[0022] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] <Online meeting status> FIG. 1 is a schematic diagram showing the situation of an online conference using a stereoscopic image display system according to an embodiment of the present invention.

[0024] For example, when developing a wire harness product to be installed in an automobile, in order to improve the efficiency of product development, many people from various departments, such as the design center of the corporate group that provides the wire harness product, domestic manufacturing centers, overseas manufacturing centers, and the design center of the automobile company that manufactures the vehicle that will be equipped with the manufactured wire harness, will participate in the same meeting and discuss the matter simultaneously.

[0025] When developing a wire harness product, it is necessary to appropriately determine the three-dimensional shape of each part of the wire harness so that it follows an appropriate routing path in accordance with the structure of the vehicle body on which it is installed and the arrangement of various electrical components. It is also necessary to appropriately determine the layout of the jigs used in manufacturing the wire harness in accordance with the three-dimensional shape of each part of the wire harness. It is also necessary to appropriately determine the manufacturing procedure, etc., so as to improve the work efficiency of the wire harness manufacturing process. Furthermore, it is necessary to appropriately determine the branching positions and wire lengths of the wire harness so as to reduce the component costs of the individual electric wires that make up the wire harness.

[0026] Therefore, the person in charge at each location must understand the three-dimensional shape of each part of the wire harness to be designed and conduct their own study from their own unique perspective. For this reason, it is common to prepare a real model and then have the people from all locations travel to the same study area to conduct their studies while looking at the same real model in the same place. This can improve the efficiency of meetings. However, since the locations are often located far from each other, such as overseas, the time and expense required to travel to hold meetings can be very burdensome.

[0027] When using the VR conference system of the embodiment, for example, by using the VR discussion space 20 shown in FIG. 1 to hold a conference, an online conference can be held without the need for personnel at each location to travel.

[0028] In the example shown in Fig. 1, it is assumed that multiple people in charge at four independent bases H1, H2, H3, and H4 simultaneously gather at a common VR review site 20 to hold a review meeting. Bases H1, H2, H3, and H4 correspond to a design base within a corporate group that provides wire harness products, a domestic manufacturing base, an overseas manufacturing base, a design base of an automobile company that manufactures vehicles equipped with the manufactured wire harnesses, etc.

[0029] At a specific location within location H1 there is a real venue V1 for the review meeting. Similarly, at specific locations within each of locations H2, H3, and H4 there are real venues V2, V3, and V4 for the review meeting, respectively.

[0030] In the example shown in Figure 1, there are one or more reviewers P11 and one or more other participants P12 in venue V1. Similarly, there are one or more reviewers P21 and one or more other participants P22 in venue V2. Furthermore, there are one or more reviewers P31 and one or more other participants P32 in venue V3. There are one or more reviewers P41 and one or more other participants P42 in venue V4.

[0031] Additionally, the venue V1 is equipped with one or more display units 11, one or more projection units 12, and one or more sets of position sensors 13 and 14 as system equipment 10A required for online conferences.

[0032] Additionally, venue V2 is equipped with system equipment 10B, which includes one or more display units 11, one or more projection units 12, and one or more sets of position sensors 13 and 14. Venue V3 is equipped with system equipment 10C, which includes one or more display units 11, one or more projection units 12, and one or more sets of position sensors 13 and 14. Venue V4 is equipped with system equipment 10C, which includes one or more display units 11, one or more projection units 12, and one or more sets of position sensors 13 and 14.

[0033] A participant P11 in venue V1 wearing a projection unit 12 included in the VR conference system can move as an avatar A11 in the virtual reality space of the VR discussion venue 20, change the posture of the avatar A11, and visually recognize the three-dimensional image 21 in the field of view at the position of the avatar A11 as an image that actually appears three-dimensional. The same is true for participants P21 to P41 in the other venues V2 to V4.

[0034] In practice, by using a projection display such as the VR goggles 15 described below, it is possible to display a three-dimensional image that can be perceived in three dimensions by creating a parallax between the image seen by the left eye and the image seen by the right eye of the examiner P11.

[0035] The VR review space 20 is a three-dimensional space virtually created by computer processing, and is formed as a box-shaped space similar to the interior of a typical conference room, for example. In the example shown in Fig. 1, a three-dimensional image 21 generated based on design data of a wire harness to be developed as a product virtually exists in the space of the VR review space 20.

[0036] Details will be given later, but more specifically, the three-dimensional image 21 includes both a three-dimensional model representing the shape of the wire harness when assembled to the vehicle body, and a three-dimensional model representing the shape of the wire harness when unfolded on a jig plate during manufacturing.

[0037] In addition, a three-dimensional image of an avatar A11, which is a character (such as a doll) corresponding to examiner P11 in venue V1, is placed in the space of the VR review area 20. In addition, three-dimensional images of avatars A21 to A24 corresponding to examiners P21 to P41 in other venues V2 to V4 are also placed in the space of the VR review area 20, respectively.

[0038] When examiner P11 moves in the real space of venue V1, position sensors 13 and 14 installed in venue V1 detect the change in position. The actual three-dimensional position change of examiner P11 detected by position sensors 13 and 14 is reflected in the three-dimensional position change of avatar A11 in the virtual space of VR review site 20. Furthermore, the actual posture change of examiner P11 is detected by projection unit 12 worn by examiner P11, and the result is reflected in the posture change of avatar A11 in VR review site 20. The same is true for examiners P21 to P41 and avatars A21 to A41 in the other venues V2 to V4.

[0039] Meanwhile, the display unit 11 placed in the venue V1 is a computer equipped with a two-dimensional display, such as a notebook computer (PC), and is connected so as to be able to cooperate with the projection unit 12 in the venue V1. Specifically, an image of the VR review area 20 of approximately the same range as the image reflected in the field of view of examiner P11 wearing the projection unit 12 in the venue V1 is displayed on the screen of the display unit 11 in synchronization with the position and attitude of the projection unit 12. Of course, since the screen of the display unit 11 is a two-dimensional display, the three-dimensional image 21 in the VR review area 20 is coordinate-converted and displayed on the two-dimensional screen of the display unit 11 as a two-dimensional image.

[0040] Similarly, the display unit 11 in venue V2 can display on the screen of the display unit 11 an image of the VR review site 20 of approximately the same range as the image reflected in the field of view of examiner P21 who is wearing the projection unit 12 in venue V2, in a state synchronized with the position and attitude of the projection unit 12. The display unit 11 in venue V3 can display on the screen of the display unit 11 an image of the VR review site 20 of approximately the same range as the image reflected in the field of view of examiner P31 who is wearing the projection unit 12 in venue V3, in a state synchronized with the position and attitude of the projection unit 12. The display unit 11 in venue V4 can display on the screen of the display unit 11 an image of the VR review site 20 of approximately the same range as the image reflected in the field of view of examiner P41 who is wearing the projection unit 12 in venue V4, in a state synchronized with the position and attitude of the projection unit 12.

[0041] The display units 11 in each of the venues V1 to V4 are placed on a desk, for example, and microphones for collecting sounds and speakers for amplifying sound in the same venue are also placed on the same desk.

[0042] By moving around the venue V1 in real space while wearing the projection unit 12, reviewer P11 in venue V1 can simultaneously move around in the virtual space of the VR review site 20. In other words, the actual movement of reviewer P11 is reflected in changes in the position and posture that reviewer P11 is looking at in the VR review site 20, and is also reflected in the content of reviewer P11's field of view projected by the projection unit 12. The same is true for reviewers P21 to P41 in the other venues V2 to V4.

[0043] The examiners P11 to P41 in each of the venues V1 to V4 can actually move around and visually grasp in detail the state of the three-dimensional shape of the part of the product or tool that they want to examine in the VR examination area 20.

[0044] Furthermore, since avatars A11 to A41 corresponding to examiners P11 to P41 in each of the venues V1 to V4 exist within the VR review area 20, each examiner P11 to P41 can immediately grasp the position and posture of examiners at other locations from the image projected by their own projection unit 12. This makes it easy for multiple examiners at different locations to simultaneously check and review the same part of a product within the VR review area 20.

[0045] Furthermore, the participants P12 to P42 other than the examiners P11 to P41 in the respective venues V1 to V4 can also see the images of the body parts that the examiners P11 to P41 are examining, based on the content displayed by the display unit 11.

[0046] On the other hand, as will be described later, the projection unit 12 at each site has a user operation unit that accepts input operations from each of the examiners P11 to P41. Also, the display unit 11 at each site has a user operation unit that accepts input operations from each of the participants P12 to P42.

[0047] Each of the examiners P11 to P41 can modify, such as change, add, or delete, the data of the 3D image 21 in the VR review site 20 by operating the user operation unit of the projection unit 12 that he or she is wearing. The modifying operation by each of the examiners P11 to P41 is recorded as data by the VR conference system and is reflected in real time on the 3D image 21. Furthermore, the result of the modifying operation performed by any of the examiners P11 to P41 is reflected in real time on the projected content of the projection units 12 of all the examiners P11 to P41 and the displayed content on the display units 11 of all the participants P12 to P42.

[0048] Therefore, all examiners P11 to P41, who are located at different locations, can use the common VR review area 20 to simultaneously review the same 3D image 21 in approximately the same field of view, and can make corrections as needed to the shape, structure, layout, etc. of the product or tool projected as the 3D image 21 and check the results of those corrections in real time. Furthermore, participants P12 to P42 other than examiners P11 to P41 can also simultaneously review the 2D image corresponding to the 3D image 21 in approximately the same field of view as examiners P11 to P41 by referring to the display screen of the display unit 11. Therefore, all participants in the online conference can efficiently proceed with their review work.

[0049] <System configuration> Fig. 2 is a block diagram showing an example of the configuration of the VR conference system 100. Fig. 3 is a block diagram showing an example of the configuration of the conference management server 30 and the projection unit 12.

[0050] In the example shown in FIG. 2, system devices 10A to 10D located at venues V1 to V4 at different locations H1 to H4 are connected via a communication network 25 so as to be able to communicate with each other.

[0051] Furthermore, in order to enable simultaneous online conferences between multiple locations H1 to H4 using the common VR review site 20, the conference management server 30 is connected to a communication network 25. The communication network 25 is expected to include local networks existing within each of the locations H1 to H4, dedicated communication lines within a company, and public communication lines such as the Internet.

[0052] If conference communications are conducted over the Internet, the security of the communications can be ensured by encrypting the data. The conference management server 30 may be installed at any one of the multiple locations H1 to H4, or may be installed in a data center or other location other than the locations H1 to H4.

[0053] The conference management server 30 shown in FIG. 3 includes a communication device 31, a participant management unit 32, database management units 33 and 34, a VR data generation unit 35, an avatar control unit 36, and a change control unit 37.

[0054] The communication device 31 has a function for securely communicating data via the communication network 25 with the system devices 10A to 10D in the respective bases H1 to H4. The participant management unit 32 has a function of managing access to each participant who participates in a common online conference as the investigators P11 to P41 or the participants P12 to P42.

[0055] The database management unit 33 holds and manages design data corresponding to wire harnesses under development. This design data includes data representing the shape, dimensions, and various components of each part of the target wire harness, as well as data representing the shapes and layouts of various jigs used in manufacturing the wire harness.

[0056] In addition, design data representing the three-dimensional shape of the wire harness when unfolded on the jig plate (first three-dimensional image: shape at the time of manufacture) and design data representing the three-dimensional shape of the wire harness when assembled to a vehicle (second three-dimensional image: shape when assembled to the vehicle body) are registered in the database management unit 33.

[0057] The database management unit 34 has a function of holding and managing update data that indicates corrections to a specific version of data held by the database management unit 33. For example, data indicating a change in the shape of a specific portion of a wire harness, data indicating the addition of a new part to a specific portion of a wire harness, data indicating the deletion of a part from a specific portion of a wire harness, etc. are sequentially registered and held in the database management unit 34 during an online conference.

[0058] The VR data generation unit 35 generates data for the 3D image 21 to be placed in the three-dimensional virtual space of the VR review site 20. The data for the 3D image 21 generated by the VR data generation unit 35 includes a 3D image corresponding to the design data of the wire harness held by the database management unit 33, a 3D image corresponding to each avatar managed by the avatar control unit 36, and a 3D image corresponding to the update data managed by the database management unit 34.

[0059] The avatar control unit 36 ​​manages the characters in the VR review area 20 as avatars A11 to A41 corresponding to each of the reviewers P11 to P41 at each of the locations H1 to H4 participating in the online conference of the VR conference system 100, and has the function of constantly monitoring the position (three-dimensional coordinates) and posture (direction of gaze) of each reviewer P11 to P41 to grasp the latest status.

[0060] The change control unit 37 has the function of accepting input operations made to the user operation unit of the projection unit 12 by each of the participants P11 to P41 at each of the locations H1 to H4 participating in the online conference of the VR conference system 100, and input operations made to the user operation unit of the display unit 11 by each of the participants P12 to P42 at each of the locations H1 to H4, as correction instructions for the three-dimensional image 21 in the VR discussion area 20, and registering them in the database management unit 34 as update data representing changes, additions, deletions, etc. to the three-dimensional image 21.

[0061] 3 includes a communication device 12a, a user position detection unit 12b, a user operation unit 12c, an audio transmission unit 12d, VR goggles 15, and a headset 16. The VR goggles 15 includes the functions of a VR image generation unit 15a, a left-eye display 15b, a right-eye display 15c, and a user posture detection unit 15d. The headset 16 also includes a built-in microphone and speaker.

[0062] The communication device 12a is connected to the conference management server 30 via the communication network 25, and can transmit and receive data to and from the conference management server 30. Specifically, data on the 3D image 21 in the VR study area 20 is periodically acquired from the conference management server 30. The data on the 3D image 21 acquired by the communication device 12a from the conference management server 30 includes design data such as the 3D shapes and jig layout of the first and second 3D images of the wire harness, as well as data on the 3D shapes, positions, and postures of the avatars A11 to A41.

[0063] Furthermore, for example, the communication device 12a in the projection unit 12 at the site H1 can periodically transmit to the conference management server 30 the three-dimensional position coordinates of the examiner P11 detected by the position sensors 13 and 14 at the site H1, and information on the posture (direction of gaze) of the examiner P11 detected by the VR goggles 15 worn by the examiner P11.

[0064] Furthermore, for example, the communication device 12a in the projection unit 12 at the site H1 is connected to the display unit 11 at the site H1, and can periodically transmit to the display unit 11 information representing the three-dimensional position coordinates of the examiner P11 and the range of the field of view of the examiner P11 in the virtual reality space, which is determined based on the posture of the examiner P11.

[0065] The user position detection unit 12b can detect the three-dimensional position coordinates and changes in the real space of each examinee P11 to P41 based on the detection state of a pair of position sensors 13 and 14 that are arranged at locations facing the examinees P11 to P41 wearing VR goggles 15 within each of the locations H1 to H4.

[0066] The user operation unit 12c is a device that can accept various button operations and coordinate input operations by the user, such as a mouse, which is a general input device. In this embodiment, the user operation unit 12c can accept input operations by the examiners P11 to P41 wearing the VR goggles 15 of the projection unit 12.

[0067] Specifically, the user can use the user operation unit 12c to issue correction instructions such as changes, additions, and deletions, such as movement, to a user-specified portion of the 3D image 21 of the VR testing field 20 projected by the VR goggles 15. In addition, instructions from the user operation unit 12c can be used to rotate the 3D image 21 within the three-dimensional space of the VR testing field 20, or to select a circuit configuration of the wire harness from multiple types and reflect it in the 3D image 21 to be projected.

[0068] The voice transmission unit 12d can transmit voice information of the examiner captured by the microphone of the headset 16 to other locations via the communication device 12a and the communication network 25. In addition, the voice transmission unit 12d can receive voice information uttered by the examiner at each of the other locations via the communication network 25 and the communication device 12a, and output the voice information from the speaker of the headset 16.

[0069] The VR goggles 15 have the function of projecting images that can be perceived three-dimensionally onto the left and right eyes of the user wearing them.

[0070] The VR video generation unit 15a constantly grasps the state of the position and posture (for example, the direction of the line of sight) of the user (reviewer P11 to P41) in the three-dimensional virtual space of the VR review site 20, and specifies the range of the user's field of view. Then, it acquires data of at least the range of the user's field of view from the data of the three-dimensional image 21 existing in the three-dimensional virtual space of the VR review site 20 from the conference management server 30, and generates two types of two-dimensional image data visible from the respective viewpoint positions of the user's left and right eyes by coordinate conversion of the data of the three-dimensional image 21.

[0071] The left-eye display 15b receives the two-dimensional image data for the left eye generated by the VR image generating unit 15a from the VR image generating unit 15a, and projects the data as a two-dimensional image onto the position of the left eye of the user.

[0072] The right-eye display 15c receives the two-dimensional image data for the right eye generated by the VR image generating unit 15a from the VR image generating unit 15a, and projects the data as a two-dimensional image onto the position of the user's right eye.

[0073] The user posture detection unit 15d detects the direction of the user's gaze by tracking the position of the pupil of the user captured by a camera, etc. Alternatively, it detects angles in three axes (roll angle, pitch angle, and yaw angle) that represent the orientation of the user's head using a three-axis acceleration sensor, etc.

[0074] Information on the user's posture detected by the user posture detection unit 15d and the position detected by the user position detection unit 12b is input to the conference management server 30 via the communication device 12a and the communication network 25. Then, the position and posture of the user are reflected in the positions and postures of the corresponding avatars A11 to A41 in the virtual reality space within the VR discussion site 20 by processing of the conference management server 30.

[0075] On the other hand, the display unit 11 shown in FIG. 2 includes a communication device 11a, a two-dimensional image generating section 11b, a two-dimensional display 11c, a user operation section 11d, and an audio transmitting section 11e.

[0076] The communication device 11a is connected to the conference management server 30 via the communication network 25 and can transmit and receive data to and from the conference management server 30. Specifically, data on the three-dimensional image 21 in the VR trial site 20 is periodically acquired from the conference management server 30.

[0077] In addition, the communication device 11a is connected to the projection unit 12 at the same location, and can obtain from the projection unit 12 the information necessary to synchronize the field of view of the examiner wearing the projection unit 12 with the display range of the display unit 11.

[0078] The two-dimensional image generating unit 11b identifies the range of the field of view of a reviewer wearing the projection unit 12 at the same site from information transmitted from the projection unit 12, and acquires data of a three-dimensional image 21 existing in the three-dimensional virtual space of the VR review site 20 for a range equivalent to the reviewer's field of view from the conference management server 30. Then, the two-dimensional image generating unit 11b generates two-dimensional image data of an image seen from the reviewer's viewpoint by performing coordinate transformation on the data of the three-dimensional image 21.

[0079] The two-dimensional display 11c displays the two-dimensional image data generated by the two-dimensional video generation unit 11b on the screen as a two-dimensional image. Note that the display unit 11 may obtain one of the two types of two-dimensional image data (left and right) generated by the VR video generation unit 15a of the VR goggles 15 from the projection unit 12 and display it on the two-dimensional display 11c.

[0080] The user operation unit 11d is a device capable of accepting various button operations and coordinate input operations by the user, such as a mouse or keyboard, which are common input devices. In this embodiment, the user operation unit 11d can accept input operations by each of the participants P12 to P42. Specifically, the user operation unit 11d can issue correction instructions, such as changes, additions, and deletions, such as movement of a user-specified portion of the 3D image 21 of the VR study area 20 displayed on the screen of the 2D display 11c. In addition, instructions from the user operation unit 11d can also rotate the 3D image 21 within the 3D space of the VR study area 20, or select from multiple types of circuit configurations of a wire harness and reflect them in the projected 3D image 21.

[0081] The voice transmission unit 11e can transmit voice information of the participants captured by the microphone of the headset 17 to other locations via the communication device 11a and the communication network 25. In addition, the voice transmission unit 11e can receive voice information uttered by reviewers and participants at other locations via the communication network 25 and the communication device 11a, and output the voice information from the speaker of the headset 17.

[0082] <System Operation Overview> An outline of the processing flow in an operation example of the VR conference system 100 is shown in Fig. 4. The processing shown in Fig. 4 will be explained below.

[0083] The VR data generation unit 35 on the conference management server 30 generates three-dimensional data of the stereoscopic image 21 in the VR space of the VR review site 20 based on the design data of the wire harness held by the database management unit 33 (S11). In addition, for each of the avatars A11 to A41 managed by the avatar control unit 36, the VR data generation unit 35 also generates three-dimensional data of the stereoscopic image 21 in the VR space of the VR review site 20. In addition, if the database management unit 34 holds update data, the data of the stereoscopic image 21 is corrected to reflect the contents of the update data.

[0084] When an online conference is started using the VR conference system 100, the projection units 12 worn by the participants P11 to P41 at each location and the display units 11 used by the participants P12 to P42 are connected to the conference management server 30 via the communication network 25 so that they can communicate with each other.

[0085] The projection unit 12 at each location acquires data of the stereoscopic image 21 within the VR review area 20 generated by the VR data generation unit 35 of the conference management server 30, and then converts the coordinates of this data into a stereoscopic image that appears in the field of view of each of the left and right eyes of each of the examiners P11 to P41, and projects it so that each examiner P11 to P41 can see it through the VR goggles 15 (S12).

[0086] In addition, the display unit 11 at each location acquires data of the three-dimensional image 21 within the VR review area 20 generated by the VR data generation unit 35 of the conference management server 30, and performs coordinate conversion of this data so that it approximately matches the three-dimensional image reflected in the field of view of each reviewer P11 to P41 at the same location, and displays it on the screen of the two-dimensional display 11c (S12).

[0087] When each examiner P11 to P41 moves in real space or changes their posture or line of sight while viewing the stereoscopic image projected by the VR goggles 15, these changes are detected by the user position detection unit 12b and the user posture detection unit 15d. Then, the changes in posture and line of sight of each examiner P11 to P41 in real space are reflected in changes in the field of view of the examiner within the VR examination field 20.

[0088] The VR image generator 15a of the VR goggles 15 updates the stereoscopic images projected onto the left-eye display 15b and the right-eye display 15c (S14) in accordance with the change in the view field of the examiner (S13). Also, the two-dimensional image generator 11b of the display unit 11 updates the image displayed on the two-dimensional display 11c (S14) so ​​as to follow the change in the view field of the examiner present at the same location (S13).

[0089] The examiners P11 to P41 at each site can change the focus area of ​​the 3D image displayed in their field of view as needed by operating the user operation unit 12c (S15). In this specification, the term "change" also includes the meanings of "add" and "delete." For example, in the process of S15, the examiners can change the shape of the focus area of ​​the wire harness, move the positions where each tool is placed, or add or delete parts or tools of the wire harness.

[0090] The correction inputs made by the reviewers P11 to P41 at each site are input from the projection unit 12 to the conference management server 30 via the communication network 25. The change control unit 37 of the conference management server 30 accepts the correction inputs from the reviewers P11 to P41 and records the contents of the corrections in the database management unit 34 as update data (S16).

[0091] When the VR data generation unit 35 of the conference management server 30 detects that new update data has been added to the database management unit 34, it generates new data for the three-dimensional image 21 by reflecting the modifications of the update data in the three-dimensional image 21 of the VR study area 20 generated by the VR data generation unit 35 (S17).

[0092] The communication device 31 of the conference management server 30 transmits the data of the corrected 3D image 21 generated by the VR data generator 35 to each of the system devices 10A to 10D at each of the locations H1 to H4 (S18).

[0093] The projection unit 12 at each location acquires the data of the corrected stereoscopic image 21 sent from the conference management server 30, and converts the coordinates of this data into a stereoscopic image that appears in the field of view of each of the left and right eyes of each examiner P11 to P41, and projects it so that each examiner P11 to P41 can see it through the VR goggles 15 (S19).

[0094] In addition, the display unit 11 at each location acquires the data of the corrected stereoscopic image 21 transmitted from the conference management server 30, and performs coordinate conversion of this data so that it approximately matches the stereoscopic image reflected in the field of view of each of the examiners P11 to P41 at the same location, and displays it on the screen of the two-dimensional display 11c (S19).

[0095] Therefore, by using the VR conference system 100 shown in Figures 2 and 3, as shown in Figure 1, all of the reviewer P11 and participant P12 at location H1, reviewer P21 and participant P22 at location H2, reviewer P31 and participant P32 at location H3, and reviewer P41 and participant P42 at location H4 can use the virtual reality space of the common VR review site 20 to hold an online conference without moving.

[0096] In particular, each examiner P11 to P41 can perceive the three-dimensional image 21 projected by the VR goggles 15 in the same three-dimensional way as the real thing, and each examiner's movements and changes in posture are reflected in their field of vision in the space of the VR examination area 20, making it easy to confirm in detail the three-dimensional shape and structure of the area that needs to be examined.

[0097] Furthermore, because avatars A11 to A41 corresponding to examiners P11 to P14 at each site are also included in the 3D image 21 in the VR review area 20, each examiner P11 to P14 can recognize the parts of the wire harness that the other examiners are checking and the direction of their gaze. In other words, even though the examiners P11 to P14 are at different sites, they can easily understand each other's relative positions, and so the task of everyone checking the common part to be examined on the 3D image 21 can be carried out as efficiently as if they were holding a meeting in a common real space.

[0098] Furthermore, examiners P11 to P14 at each site can perform input operations as necessary to make corrections such as changes, additions, and deletions to the 3D image 21. In addition, the results of the correction operations are reflected in the content of the 3D image 21 that is projected, so examiners P11 to P14 at each site can easily grasp the 3D shape and structure of the 3D image 21 after correction.

[0099] Furthermore, participants P12 to P42 at each location can confirm a two-dimensional image of approximately the same range as the three-dimensional image 21 reflected in the field of view of examiners P11 to P14 at the same location on the screen display of display unit 11. Therefore, even if there is no actual model or the like in each of venues V1 to V4, participants P12 to P42 can easily grasp the shape and structure of the part to be examined, just like examiners P11 to P14.

[0100] <Examples of 3D images> FIG. 5 is a schematic diagram showing a representative example of a three-dimensional image 21 formed in the VR examination field 20. As shown in FIG. As shown in FIG. 5, a stereoscopic image 21 formed in a VR examination field 20 includes both a first stereoscopic image 22 and a second stereoscopic image 23 .

[0101] The shape of the wire harness WH2 of the second three-dimensional image 23 is determined by the design data so as to match the three-dimensional shape of the wire harness in the routed state when the wire harness is actually assembled in a vehicle.

[0102] On the other hand, the shape of the wire harness WH1 of the first three-dimensional image 22 is determined based on the design data so as to match the three-dimensional shape of the wiring state of the electric wire groups at each part in the actual wire harness manufacturing process. In other words, the wire harness WH1 of the first three-dimensional image 22 represents the three-dimensional shape when the shape of the wire harness WH2 is developed in a plane and placed on the top surface of the flat jig plate 24.

[0103] Therefore, the two types of wire harnesses WH1 and WH2 are products with the same structure, but differ from each other only in their three-dimensional shapes. Specifically, the shape of the wire harness WH2 in the second three-dimensional image 23 has large undulations in the vertical direction so as to match the shape of the space above the vehicle. Furthermore, since the wire harness WH1 has groups of wires in each section arranged so as to follow the positions of the jigs on the upper surface of the jig plate 24, the shape of the wire harness WH1 in the first three-dimensional image 22 has small undulations in the vertical direction.

[0104] A user of the VR conference system 100 can view the three-dimensional image 21 of the VR discussion area 20 using the display unit 11 or the projection unit 12, and can compare and consider both the first three-dimensional image 22 and the second three-dimensional image 23.

[0105] <Positional relationship between the first and second 3D images> 6 is a schematic diagram showing an example of two reference planes Sr1 and Sr2 that determine the positional relationship between the first stereoscopic image 22 and the second stereoscopic image 23. The coordinates of each part in the three-dimensional space of the VR testing field 20 can be expressed by the position in each of the X, Y, and Z axis directions as shown in FIG.

[0106] 5, when two types of first and second stereoscopic images 22 and 23 are simultaneously displayed as a stereoscopic image 21, the first and second stereoscopic images 22 and 23 are aligned with two parallel reference planes Sr1 and Sr2 that are offset by a certain distance H in the height direction (Z-axis direction). This positions the first and second stereoscopic images 22 and 23 adjacent to each other, facilitating the examiner's work of comparing and examining them.

[0107] Specifically, when the first stereoscopic image 22 is placed in the space of the VR examination field 20, it is assumed that the coordinates of the first stereoscopic image 22 are aligned, for example, with the upper surface position of the jig plate 24 coinciding with the reference plane Sr1 in Fig. 6. Also, when the second stereoscopic image 23 is placed in the space of the VR examination field 20, it is assumed that the second stereoscopic image 23 is aligned, for example, with the planar position of the floor surface inside the vehicle compartment coinciding with the reference plane Sr2 in Fig. 6.

[0108] This makes it possible to display the stereoscopic image 21 shown in FIG. 5 in the VR examination field 20 by arranging the first stereoscopic image 22 and the second stereoscopic image 23 vertically adjacent and substantially parallel to each other.

[0109] Furthermore, the stereoscopic image 21 can be rotated by coordinate transformation within the VR examination field 20. For example, the first stereoscopic image 22 and the second stereoscopic image 23 are each rotated in a rotation direction 26 around a rotation axis 27 passing through the center positions of the reference planes Sr1 and Sr2 shown in Fig. 6. This allows the parts of the stereoscopic image 21 reflected in the field of view of each examiner to be switched without the examiners P11 to P41 etc. moving.

[0110] <Display operation processing> Fig. 7 is a flowchart showing an example of processing in response to a user's display operation. For example, upon receiving a user's input operation on the user operation unit 12c or 11d, the projection unit 12, the display unit 11, or the conference management server 30 executes the processing in Fig. 7. The processing in Fig. 7 will be described below.

[0111] In this embodiment, it is assumed that the stereoscopic image 21 can be selectively displayed for each of wire harnesses having a predetermined initial circuit configuration, a maximum circuit configuration, a minimum circuit configuration, and a circuit configuration including only thick wires.

[0112] The maximum circuit configuration refers to a wire harness configuration with the maximum number of parts and wires, which has the functionality of a wire harness that can connect to all electrical equipment that can be installed on a vehicle of the same model, including options.The minimum circuit configuration refers to a wire harness configuration with the minimum number of parts and wires, which has the functionality of connecting to the minimum number of electrical equipment required for a vehicle with a basic configuration (e.g., base grade) that does not include options.A circuit configuration using only thick wires refers to a configuration that is limited to only circuits that use thick wires, such as power lines and ground lines, out of the various circuits that make up a wire harness.

[0113] When the user instructs the selection of the maximum circuit configuration using the user operation unit 12c or 11d, the VR data generation unit 35 of the conference management server 30 extracts the design data of the wire harnesses WH1 and WH2 with the maximum circuit configuration from the database management unit 33, and generates data for the first stereoscopic image 22 and the second stereoscopic image 23 in the VR space of the VR review site 20 (S22).

[0114] When the user instructs the selection of the minimum circuit configuration using the user operation unit 12c or 11d, the VR data generation unit 35 of the conference management server 30 extracts the design data of the wire harnesses WH1 and WH2 with the minimum circuit configuration from the database management unit 33, and generates data for the first stereoscopic image 22 and the second stereoscopic image 23 in the VR space of the VR review site 20 (S24).

[0115] When the user instructs the selection of thick electric wires only using the user operation unit 12c or 11d, the VR data generation unit 35 of the conference management server 30 extracts design data for wire harnesses WH1 and WH2 with a circuit configuration limited to thick electric wires from the database management unit 33, and generates data for the first three-dimensional image 22 and the second three-dimensional image 23 in the VR space of the VR review site 20 (S26).

[0116] Also, if the user does not instruct the selection of a configuration, the VR data generation unit 35 of the conference management server 30 extracts design data of the wire harnesses WH1 and WH2 with a predetermined initial circuit configuration from the database management unit 33, and generates data for the first stereoscopic image 22 and the second stereoscopic image 23 in the VR space of the VR review site 20 (S27).

[0117] Furthermore, when the user instructs the rotation of the three-dimensional image using the user operation unit 12c or 11d, the VR data generation unit 35 of the conference management server 30 performs coordinate conversion of the data of the first three-dimensional image 22 and the second three-dimensional image 23 in the VR space of the VR study area 20 according to the rotation direction and rotation angle within the VR space, and generates data after the rotation process (S29).

[0118] <Processing of change operations> Fig. 8 is a flowchart showing an example of processing in response to a user's change operation. For example, upon receiving a user's input operation on the user operation unit 12c or 11d, the projection unit 12, the display unit 11, or the conference management server 30 executes the processing in Fig. 8. The processing in Fig. 8 will be described below.

[0119] The examiners P11 to P41 and the participants P12 to P42 can change the focus area of ​​the 3D image displayed in their field of view as needed by operating the user operation units 12c and 11d. For example, they can change the shape of the focus area of ​​the wire harness, move the positions where each tool is placed, or perform correction operations such as adding or deleting parts or tools of the wire harness.

[0120] As shown in FIG. 5, the VR review area 20 contains a wire harness WH1 laid out on a fixture plate as the wire harness to be corrected, and a wire harness WH2 assembled in a vehicle. In this embodiment, the first three-dimensional image 22 of the wire harness WH1 is corrected first.

[0121] That is, the user's correction input is first reflected as a change, addition, or deletion to a part of the first stereoscopic image 22, and is reflected in the design data in the database management units 33 and 34 (S32).

[0122] Then, the content of the corrected first 3D image 22 is reflected as a change, addition, or deletion to a part of the second 3D image 23 of the wire harness WH2, and is also reflected in the design data of the database management units 33 and 34 (S33). Furthermore, the data of both the first stereoscopic image 22 and the second stereoscopic image 23 after correction are displayed by the display unit 11 and the projection unit 12 as the contents of the VR examination field 20 (S34).

[0123] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0124] For example, in the above embodiment, the VR conference system 100 is described as being capable of simultaneously holding online conferences at multiple locations, but the stereoscopic image display system of the present invention can be realized by using one or more projection units 12 placed at a single location. Also, it is possible to incorporate functions equivalent to the conference management server 30 into the projection unit 12, or the conference management server 30 may be placed near the projection unit 12.

[0125] The distinctive features of the above-mentioned stereoscopic image display system are briefly summarized and listed below in [1] to [5]. [1] A 3D image generating device (VR data generating unit 35) that generates 3D image data of the wire harness based on design data of the wire harness; a projection unit (12) that acquires the stereoscopic image data from the stereoscopic image generating device and projects a stereoscopic image based on the stereoscopic image data into a VR space that can be recognized by a user; the three-dimensional image data includes first three-dimensional image data representing the wire harness (WH1) in a state where it is laid out on a jig plate (24), and second three-dimensional image data representing the wire harness (WH2) in a state where it is assembled to a vehicle; The projection unit projects a first stereoscopic image (22) based on the first stereoscopic image data and a second stereoscopic image (23) based on the second stereoscopic image data, aligning them so that they are adjacent to each other (FIG. 5). Stereoscopic image display system.

[0126] According to the 3D image display system configured as described above in [1], the user can easily compare the shape of the wire harness laid out on the fixture plate with the shape of the same wire harness assembled in the vehicle by recognizing the 3D image projected by the projection unit. Moreover, since the user can recognize the shape of each part of the wire harness in 3D in the VR space, it becomes easy to check the shape of the details.

[0127] [2] An input operation unit (user operation unit 12c) capable of accepting input operations by the user; the projection unit has a display direction change unit (S28, S29) that changes the direction of the first stereoscopic image and the second stereoscopic image projected in response to the input from the input operation unit; The stereoscopic image display system according to [1] above.

[0128] According to the 3D image display system having the configuration [2] above, the orientation of the projected first and second 3D images can be changed within the VR space, so that the user can view and check each part of the same wire harness from different directions without having to actually move and change the user's viewpoint within the VR space.

[0129] [3] An input operation unit (user operation unit 12c) capable of accepting input operations by the user; The projection unit or the stereoscopic image generating device includes a change processing unit (S31, S32) that performs change, addition, and / or deletion processing on the first stereoscopic image by reflecting input from the input operation unit, and a processing reflection unit (S33) that reflects the result of processing on the first stereoscopic image on the second stereoscopic image. The stereoscopic image display system according to [1] or [2] above.

[0130] According to the 3D image display system having the configuration of [3] above, the user can input changes to the first 3D image to resolve issues that may arise when manufacturing the target wire harness. Furthermore, because the changes to the first 3D image are reflected in the second 3D image, the user can easily check whether any new issues will arise when the modified wire harness is installed in a vehicle.

[0131] [4] An input operation unit capable of accepting an input operation by the user, The projection unit or the stereoscopic image generating device has a display selection unit (S21 to S27) that reflects input from the input operation unit and enables selective display of at least one of a stereoscopic image with a maximum circuit configuration, a stereoscopic image with a minimum circuit configuration, and a stereoscopic image with a circuit configuration limited to only a portion. The stereoscopic image display system according to any one of [1] to [3] above.

[0132] The 3D image display system configured as described above in [4] allows the user to selectively project a more appropriate 3D image according to the problem or purpose to be considered. For example, by projecting an image limited to only the thick electric wires among the electric wires that make up a wire harness, it becomes easy to examine in detail the ease of bending the thick electric wires when they are bent to fit the wiring route on the vehicle, and the change in the tip position.

[0133] [5] The projection unit projects the first stereoscopic image and the second stereoscopic image by aligning a reference plane (Sr1) in the first stereoscopic image and a reference plane (Sr2) in the second stereoscopic image so that they are aligned parallel to each other and spaced apart by at least a certain distance (H) in the vertical direction. A stereoscopic image display system according to any one of [1] to [4] above.

[0134] According to the stereoscopic image display system having the configuration described above in [5], the first and second stereoscopic images, which are slightly different in shape from each other, are projected side by side in a nearly parallel state, so that the user can easily understand the differences in shape and position by comparing the two images.
