Description

[Technical Field]

[0001] The present invention relates to a server and a system. [Background technology]

[0002] Various technologies have been proposed for delivering VR video to VR goggles worn by passengers of a vehicle in response to the movement of the vehicle. For example, Patent Document 1 (Patent Document 1) describes a vehicle system including at least one vehicle, electronic goggles worn by the passengers, and a system communicatively connected to the electronic goggles. The system generates streaming media of a real-world environment based on image data captured by a camera in the electronic goggles, generates virtual augmentations to be superimposed on the streaming media of the real-world environment, and transmits the streaming media of the real-world environment together with the virtual augmentations to be displayed on a display of the electronic goggles. Patent Document 1 also describes the inclusion of an accelerometer, magnetometer, gyroscope, and GPS receiver in the electronic goggles to track the position, direction, and movement of passengers and generate video corresponding to the position of each passenger.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-166405 Summary of the Invention [Problem to be solved by the invention]

[0004] In the technology described in Patent Document 1, if an accelerometer, magnetometer, gyroscope, etc. is used to detect the position of each passenger on the ride, only the relative position to the ride can be detected, making it difficult to generate images that take into account the movement of the roller coaster.On the other hand, if the technology described in Patent Document 1 uses GPS to detect the position of each passenger, it becomes difficult to generate images that accurately reflect differences in position within the ride.

[Figure 6] FIG. 10 is a block diagram showing an example of a schematic configuration of a moving body according to an embodiment of another invention. DETAILED DESCRIPTION OF THE INVENTION

[0009] <System> First, an embodiment of a system S according to one aspect of the present invention will be described in detail.

[0010] 1, the system S includes a mobile object 1, a first measurement unit 2, a second measurement unit 3, and a server 4. The system S according to this embodiment further includes a third measurement unit 5 and a fourth measurement unit 6.

[0011] [Moving object] The moving body 1 is a vehicle configured to accommodate multiple people. The moving body 1 includes vehicles (automobiles, railroad cars), ships, aircraft, gondolas, elevator cars, and mobile play equipment (roller coasters, etc.).

[0012] [First measurement section] The first measurement unit 2 measures a first relative position. The first relative position is the relative position of the moving object 1 with respect to a fixed point P, which has an absolute position. The first measurement unit 2 repeatedly measures the first relative position in the form of coordinates (X, Y) of a predetermined location of the moving object 1 (e.g., a corner of the moving object 1) on a horizontal plane (XY plane) with the fixed point P as the origin. In the example shown on the left side of FIG. 2, the first relative position is (3, 3). The first measurement unit 2 may be provided in the moving object 1 or in facilities (roads, signs, guardrails, buildings, etc.) present on the moving object 1's movement path. When the first measurement unit 2 is provided in the moving object 1, the moving object 1 has the function of measuring its own position. In this case, the first measurement unit 2 is configured with, for example, a LiDAR, a RaDAR, a VPS (Visual Positioning System), etc. On the other hand, when the first measurement unit 2 is provided in facilities present on the moving object 1's movement path, the first measurement unit 2 is configured with, for example, a device that energizes an electromagnetic induction line, a receiver that receives radio waves from an RFID marker mounted on the vehicle, etc. The moving object 1 or facility equipped with the first measuring unit 2 transmits first position information indicating the first relative position to the server 4 every time the first measuring unit 2 measures the first relative position.

[0013] [Second measurement section] The second measurement unit 3 measures the second relative position. The second relative position is the relative position of the occupant of the moving body 1 with respect to the moving body 1. The second measurement unit 3 repeatedly measures the second relative position in the form of the occupant's coordinates (X, Y) on a horizontal plane with a predetermined location on the moving body 1 (for example, a corner of the moving body 1) as the origin. In the example shown on the right side of FIG. 2, the second relative position is (1, 2). The second measurement unit 3 may be provided in a device carried or worn by the occupant, or may be provided in the moving body 1. When the second measurement unit is provided in a device, the second measurement unit 3 is composed of a VPS, Visual-SLAM, LiDAR-SLAM, Depth-SLAM, AR marker, IMU, etc. On the other hand, when the second measurement unit is provided in the moving body 1, the second measurement unit 3 is composed of receivers for various beacons, an image analysis device for road cameras, etc. The device or moving object 1 equipped with the second measuring unit 3 transmits second position information indicating the second relative position to the server 4 every time the second measuring unit 3 measures the second relative position.

[0014] [Third measurement section] The third measurement unit 5 measures the orientation of the passenger relative to the traveling direction of the moving body 1. The third measurement unit 5 repeatedly measures the orientation of the passenger in the form of an angle θ with respect to the traveling direction of the moving body 1 (the direction (upward) indicated by the white arrow on the left side of FIG. 2). The third measurement unit 5 may be provided in a device carried or worn by the passenger, or may be provided in the moving body 1. When the third measurement unit 5 is provided in the device, the third measurement unit 5 is composed of an acceleration sensor, etc. On the other hand, when the third measurement unit 5 is provided in the moving body 1, the first measurement unit 2 is composed of, for example, a camera that photographs the passenger, and an analysis device that analyzes the image of the passenger generated by the camera and calculates the orientation of the passenger's face, etc. The device or moving body 1 equipped with the third measurement unit 5 transmits directional information indicating the orientation to the server 4 each time the third measurement unit 5 measures the orientation.

[0015] [Fourth measurement section] The fourth measurement unit 6 measures the height of the passenger's line of sight from the floor inside the moving body 1. The second measurement unit 3 repeatedly measures the height of the line of sight in the form of the passenger's vertical coordinate (Z) in a space with a predetermined location on the moving body 1 (for example, a corner of the moving body 1) as the origin. The fourth measurement unit 6 is configured in the same manner as the second measurement unit 3. When the fourth measurement unit 6 measures the orientation of the device or moving body 1 equipped with the fourth measurement unit 6, it transmits height information indicating the height of the line of sight to the server 4. Note that the height information may be input to the server 4 via an input device. In this case, the system S may not be equipped with the fourth measurement unit 6.

[0016] [server] The server 4 is installed outside or inside the moving object 1. The server 4 according to this embodiment includes a server communication unit 41 (communication unit), a storage unit 42, and a server calculation unit 43.

[0017] [Server Communication Department] The server communication unit 41 communicates with the mobile object 1. The server communication unit 41 according to this embodiment is configured with a communication module. The server communication unit 41 may communicate directly with the mobile object 1, or may communicate indirectly with the mobile object 1 via a base station or the like.

[0018] [Storage section] The storage unit 42 stores a program 421. The program 421 describes the processes to be executed by the server 4. The storage unit 42 according to this embodiment is configured with a semiconductor memory, a hard disk, and the like.

[0019] [Server Calculation Unit] The server computing unit 43 includes a first acquisition unit 431, a second acquisition unit 432, a calculation unit 433, and a generation unit 434. The server computing unit 43 according to this embodiment includes a third acquisition unit 435, a fourth acquisition unit 436, and a transmission processing unit 437. The server computing unit 43 according to this embodiment is configured with a processor. The server computing unit 43 executes the process shown in FIG. 3 in accordance with the program 421 stored in the storage unit 42. This process includes a first acquisition step S1, a second acquisition step S2, a calculation step S3, and a generation step S4. The process according to this embodiment further includes a third acquisition step S5, a fourth acquisition step S6, and a transmission step S7.

[0020] (First acquisition step, first acquisition unit) In the first acquisition step S1, the first acquisition unit 431 acquires first location information. The first acquisition unit 431 according to this embodiment acquires the first location information received by the server communication unit 41 from the first measurement unit 2. That is, when the first measurement unit 2 is provided in the mobile object 1, the first acquisition unit 431 acquires the first location information from the mobile object 1. On the other hand, when the first measurement unit 2 is provided in a facility located on the movement path of the mobile object 1, the first acquisition unit acquires the first location information from a device that is provided outside the mobile object 1 and that measures the position of the mobile object 1.

[0021] (Second acquisition step, second acquisition unit) In the second acquisition step S2, the second acquisition unit 432 acquires the second location information. The second acquisition unit 432 according to this embodiment acquires the first location information received by the server communication unit 41 from the second measurement unit 3. That is, when the second measurement unit 3 is provided in a terminal, the second acquisition unit 432 acquires the second location information from a terminal that is carried or worn by the passenger and has a device for measuring its own location. On the other hand, when the second measurement unit 3 is provided in a device, the second acquisition unit 432 acquires the second location information from a device that is provided in the moving object 1 and measures the passenger's location.

[0022] (Third acquisition step, third acquisition unit) In the third acquisition step S5, the third acquisition unit 435 acquires direction information.

[0023] (Fourth acquisition step, fourth acquisition unit) In a fourth acquisition step S6, the fourth acquisition unit 436 acquires height information.

[0024] (Calculation step, calculation part) In calculation step S3, the calculation unit 433 calculates a third relative position based on the first relative position acquired by the first acquisition unit 431 and the second relative position acquired by the second acquisition unit 432. The third relative position is the position of the passenger relative to the fixed point P. As described above, the first relative position and the second relative position are expressed in the form of coordinates (X, Y). Therefore, the calculation unit 433 according to this embodiment calculates the third relative position by adding up the X coordinates and the Y coordinates of the first relative position and the second relative position, respectively. In the example shown in FIG. 2, the third relative position is (3+1, 3+2)=(4, 5).

[0025] (Generation step, generation unit) In generation step S4, the generation unit 434 generates perceptual information in a manner as if the passenger perceived it from the third relative position, based on the third relative position calculated by the calculation unit 433. The perceptual information is information to be perceived by the passenger, and includes an image, a sound, an impact, wind, a temperature, or a combination thereof. The manner includes the size, direction, orientation, etc. of the perceptual information. The generation unit 434 according to this embodiment generates video data of an object to be visually recognized by the passenger. Therefore, the generation unit 434 according to this embodiment generates video data of an object with a size and orientation as if the passenger perceived it from the third relative position. For example, consider a case where the moving object is a bus as shown in FIG. 4 and a video of an object that appears to be located to the front right of the bus is generated. In this case, the generation unit 434 generates video data in which the object appears to be located to the right (directly to the side) of the bus for passenger A seated in the front of the bus. On the other hand, the generation unit 434 generates video data in which the object appears to be located diagonally forward to the right for passenger B seated in the rear of the bus.

[0026] Furthermore, in the server 4 according to this embodiment, the third acquisition unit 435 acquires direction information as described above. Therefore, the generation unit 434 according to this embodiment refers to the direction information and generates video data of a case where a passenger looks from the third relative position in the direction indicated by the direction information. For example, when the head (line of sight) of passenger A is facing right, the generation unit 434 generates video data in which an object appears to be in front of passenger A, even though it is to the right (directly to the side) of the bus. Here, when passenger A turns his head to the front, the generation unit 434 generates video data in which the object gradually moves to the right as the head turns. On the other hand, when passenger B's head (line of sight) is facing the traveling direction of the bus, the generation unit 434 generates video data in which the object appears to be in front of passenger A, even though it is to the right (directly to the side). Here, when passenger B turns his head to the right, the generation unit 434 generates video data in which the object gradually moves to the left as the head turns.

[0027] Furthermore, in the server 4 according to this embodiment, the fourth acquisition unit 436 acquires height information as described above. Therefore, the generation unit 434 according to this embodiment references the height information and generates video data that would be viewed by a passenger from the third relative position at the eye level indicated by the height information. For example, consider a case where the moving object is a bus as shown in FIG. 5 and a video of an object that appears to be located to the side of the bus is to be generated. In this case, the generation unit 434 generates video data in which the object appears to be located to the right (directly to the side) of the bus for passenger A, whose eye level is relatively high from the floor. On the other hand, for another passenger B who is near the passenger (e.g., sitting in the seat next to him) and whose eye level is relatively low from the floor, the generation unit 434 generates video data in which the object appears to be located diagonally above him.

[0028] The generation unit 434 may generate video data of an object for Augmented Reality (AR) that allows the passenger to visually recognize the object superimposed on an object that actually exists.

[0029] (Transmission step, transmission processing unit) In a transmission step S7, when the generation unit 434 generates the sensory information, the transmission processing unit 437 controls the server communication unit 41. As a result, the server communication unit 41 transmits the sensory information to an output device corresponding to the passenger. When the sensory information is video, the output device includes VR goggles worn by the passenger, a transparent display laminated on a window glass near the passenger's seat in the vehicle, etc. The server communication unit 41 according to this embodiment transmits the video data to a display device. The server communication unit 41 transmits the video data to a transparent display device corresponding to the passenger. When the sensory information is audio, the output device includes headphones worn by the passenger, a speaker arranged near the passenger's seat in the vehicle, etc.

[0030] (Action and effect) The server 4 described above repeatedly acquires the first relative position of the moving object 1 and the second relative position of the passenger, and repeatedly calculates the passenger's absolute position (third relative position) based on the acquired information. Therefore, even when the moving object 1 is moving, the server 4 can constantly grasp the passenger's absolute position and generate perceptual information with different appearances (appearances) for each passenger. Therefore, the server 4 can provide passengers aboard a moving moving object with a highly accurate (highly realistic, without positional deviation, etc.) virtual experience that reflects differences in the passenger's position. For example, it is possible to project virtual space content or characters onto the outside of the bus through an XR device onto the bus window. This makes it possible to provide an entertainment experience in which the moving object 1 runs through a virtual space (e.g., a safari park).

[0031] <Mobile> Next, a moving object 1 according to another embodiment of the present invention will be described in detail.

[0032] As shown in FIG. 6, the mobile object 1 according to this embodiment includes a mobile object communication unit 11, a plurality of display units 12, and a mobile object calculation unit 13.

[0033] [Mobile Communications Department] The mobile communication unit 11 communicates with the server 4 .

[0034] [Display] A plurality of display units 12 are provided inside the moving body 1. The display units according to this embodiment are configured with display devices (liquid crystal displays, organic EL displays, etc.). The display units 12 may be configured with transmissive display devices. In this case, the display units 12 are laminated on the window glass of the moving body. In this way, passengers can enjoy images superimposed on the scenery outside the window.

[0035] [Control Unit] The mobile object calculation unit 13 includes an acquisition unit 131 and a display control unit 132.

[0036] (Acquisition Department) The acquisition unit 131 acquires from the server 4 a plurality of pieces of video data that are to be visually recognized by a passenger of the moving body 1 and that have different third relative positions that were the basis for generating the video data.

[0037] (Display control unit) The display control unit 132 causes the corresponding display units 12 to display a plurality of types of video based on the plurality of video data.

[0038] (Action and effect) The moving body 1 described above displays images (content, characters, etc.) that look different depending on the location of the person riding on each of the multiple display units 12. Therefore, the moving body 1 can provide passengers with a more realistic entertainment experience.

[0039] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and various modifications are possible within the scope of the claims. Furthermore, embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.

[0040] For example, in the above embodiment, it has been described that the present invention can provide an entertainment experience to passengers of a moving body, but the present invention also makes it easy to associate real space coordinates with XR space coordinates, including those of a moving body. Therefore, the present invention is not limited to the entertainment field, and can also be applied to technologies in other fields, such as the digital twin field.
