DETAILED DESCRIPTION OF THE INVENTION

[0026] In order to make the above-mentioned objects, features and advantages of the present disclosure more clearly understood, the present disclosure will be further described below. It should be noted that, unless contradictory, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0027] In the following description, many specific details are set forth to provide a thorough understanding of the present disclosure, but the present disclosure may be implemented in ways different from those described herein. Obviously, the embodiments in the specification are only some embodiments of the present disclosure, but not all embodiments.

[0028] In the embodiments of the present disclosure, terms such as "exemplary" or "for example" are used to denote an example, illustration, or explanation. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as preferred or advantageous over other embodiments or design solutions. Rather, the invocation of terms such as "exemplary" or "for example" is intended to present the related concept in a concrete manner. Note that in the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more than two.

[0029] In the related art, the dimensions of the virtual display interface shown in the augmented reality environment are determined based on experience, but when the related art is adopted, the user's viewing experience of the virtual display interface is poor.

[0030] In view of this, the embodiments of the present disclosure provide a method and apparatus for displaying a virtual display interface in an augmented reality space to solve the problem of a user's poor viewing experience of the virtual display interface.

[0031] A method for displaying a virtual display interface in an augmented reality space according to an embodiment of the present disclosure includes first obtaining map information of the real space using an image capturing device, then generating an augmented reality space using a rendering engine based on the map information of the real space, and finally determining a target position in the augmented reality space for the virtual display interface, and displaying the virtual display interface at the target position. Since the dimensions of the virtual display interface are related to the target position where the virtual display interface is located and the user's visual range, more reasonable dimensions of the virtual display interface can be determined based on the target position where the virtual display interface is located and the user's visual range, thereby solving the problem of users' poor viewing experience of the virtual display interface.

[0032] In an augmented reality space, a virtual display interface is displayed in a three-dimensional space surrounded by 360°, and the virtual display interface is not constrained by the size of a physical device. Based on this, the present disclosure determines the dimensions of the virtual display interface in the augmented reality space based on the display position of the virtual display interface and the user's visual range, thereby making the setting of the dimensions of the virtual display interface more rational and improving the user's viewing experience of the virtual display interface.

[0033] The technical solution of the present disclosure may be applied to an augmented reality scene, where augmented reality includes but is not limited to AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality), etc. The following describes the technical solution of the present disclosure through several embodiments.

[0034] FIG. 1 is a schematic flowchart of a method for displaying a virtual display interface in an augmented reality space according to an embodiment of the present disclosure. Referring to FIG. 1, the method for displaying a virtual display interface in an augmented reality space includes the following steps S11 to S13.

[0035] S11: Obtain map information of the real space using an image collection device.

[0036] Here, the image collection device includes, but is not limited to, radar device, device with imaging function, etc. Here, the radar device may be a laser radar, and the device with imaging function may be a camera, a video capture card, a scanner, etc.

[0037] The map information of the real space includes, but is not limited to, three-dimensional coordinate information of each object in the real space or relative position information of each object.

[0038] S12: An augmented reality space is generated by a rendering engine based on the map information of the real space.

[0039] Here, the rendering engine may be a 3D rendering engine such as Unity or UE (Unreal Engine).

[0040] Specifically, an augmented reality space is generated by a rendering engine based on the map information of the real space acquired in the above steps. The head-mounted device may be in the form of glasses, and the position of the head-mounted device in the SLAM (simultaneous localization and mapping) environment is used as the initial alignment of the human eye, and mapping is performed by a 3D engine such as Unity or UE, and the augmented reality space can be constructed by performing accurate conversion to the distance data in the environment.

[0041] S13: Determine a target position in the augmented reality space for a virtual display interface, and display the virtual display interface at the target position, and the dimensions of the virtual display interface are related to the target position where the virtual display interface is located and the user's visual range.

[0042] Determining the target position in the augmented reality space of the virtual display interface includes, but is not limited to, the following possible implementations.

[0043] Based on the attribute information of the virtual display interface, distance information between the virtual display interface and the initial position of the head-mounted device is determined, and based on the distance information, a target position of the virtual display interface in the augmented reality space is determined, and the virtual display interface is displayed at the target position.

[0044] Here, the attribute information of the virtual display interface may be the type of the virtual display interface. For example, the attribute information of the virtual display interface may be a virtual display screen of a movie theater, a virtual display screen of an office, a virtual display screen of a real-life map of a department store, a virtual display screen of a topographical model of a tourist attraction, etc. The distance information between the virtual display interface and the initial position of the head-mounted device may be determined based on historical experience. Taking Table 1 as an example, the relationship between the attribute information of the virtual display interface and the distance information between the virtual display interface and the initial position of the head-mounted device may be as shown in Table 1. [Table 1]

[0045] Illustratively, taking FIG. 2 as an example, when the attribute information of the virtual display interface is a virtual display screen of a movie theater, it determines that the distance information between the virtual display interface and the initial position of the head-mounted device is 3 meters, and determines a target position in the augmented reality space of the virtual display interface based on the distance information, and displays the virtual display interface at the target position.

[0046] Furthermore, the shape of the virtual display interface is described as a rectangle by way of example, but may be other shapes, and the present disclosure is not limited thereto. The horizontal dimension of the virtual display interface refers to the maximum length in the horizontal direction, for example, a rectangle refers to the length of a side in the horizontal direction, and the vertical dimension of the virtual display interface refers to the maximum length in the vertical direction, for example, a rectangle refers to the length of a side in the vertical direction.

[0047] The horizontal dimension is determined based on the distance information and a predetermined horizontal viewing angle, and the vertical dimension of the virtual display interface is determined based on the distance information and a predetermined vertical viewing angle.

[0048] Specifically, according to ergonomic calculations, the optimal horizontal visual range for both eyes when the human head is not rotated is 60°, and the vertical clear vision range is 25° above to 30° below. Using Figure 3 as an example, the optimal visual range for each distance d can be calculated based on the ergonomically most comfortable angle α, i.e., w = 2d tan(α / 2), to obtain the optimal visual range for the human eyes in the augmented reality space. Therefore, the preset horizontal visual angle α can be set to 60°, and the preset vertical visual angle α can be set to 55°.

[0049] For example, when the dimensions of the virtual display screen of a real-life map of a department store are set, the preset horizontal visible angle α is 60°, the preset vertical visible angle α is 55°, and when the distance d is 1 meter, the horizontal dimension of the virtual display screen of the real-life map of the department store is w=2tan30°≒1.15 meters, and the vertical dimension of the virtual display screen of the real-life map of the department store is w=2tan27.5°≒1.04 meters. Therefore, the visual clear view range at 1 meter is 11.5×1.04m 2 Using this data in the rendering engine, we can indicate the canvas for the optimal viewing range at 1 meter, and infer other positions based on this.

[0050] In a method for displaying a virtual display interface in an augmented reality space according to an embodiment of the present disclosure, first, map information of the real space is obtained by an image capturing device, then, an augmented reality space is generated by a rendering engine based on the map information of the real space, and finally, a target position of the virtual display interface in the augmented reality space is determined, and the virtual display interface is displayed at the target position. Since the dimensions of the virtual display interface are related to the target position where the virtual display interface is located and the user's visual range, more reasonable dimensions of the virtual display interface can be determined based on the target position where the virtual display interface is located and the user's visual range, thereby solving the problem of users' poor viewing experience of the virtual display interface.

[0051] As one optional embodiment of the present disclosure, the following steps may be further performed before determining distance information between the virtual display interface and the initial position of the head-mounted device based on attribute information of the virtual display interface.

[0052] A call command for a virtual display interface is received, and attribute information of the virtual display interface is obtained based on the call command.

[0053] For example, the command to call the virtual display interface may be a command issued by the user through voice or through a key on the terminal device.

[0054] In some embodiments, a user may move in the augmented reality space, and the user may be far away from the virtual display interface or close to the virtual display interface. Therefore, in order to achieve a better viewing experience for the user, the present disclosure provides an implementation method for readjusting the position information of the virtual display interface by setting a reset command. The reset command may be triggered by an interaction device, for example, the reset command may be triggered by a preset key on a steering wheel or a preset key on a head-mounted device, or may be triggered by a key on a displayed virtual interaction interface, or may even be triggered by a voice command. The present disclosure is not limited thereto.

[0055] After receiving the reset command, the process returns to S11 and executes S11 to S13.

[0056] Specifically, each time the virtual display device receives a reset command, it returns to the process of acquiring map information of the real space using the image collecting device, acquires the map information of the real space using the image collecting device, and generates an augmented reality space using the rendering engine based on the map information of the real space, and finally determines a target position of the virtual display interface in the augmented reality space, and displays the virtual display interface at the target position. Here, for detailed implementation of each step, you may refer to the description of the embodiment shown in Figure 1, and the description will be omitted here. By adjusting the target position of the virtual display interface using the reset command, a better viewing effect can be achieved when the user views the virtual display interface.

[0057] The present disclosure further provides an implementation in which, upon detecting movement of a head-mounted device in the augmented reality space, dimensions of the virtual display interface are adjusted based on the displacement of the movement.

[0058] Specifically, when the head-mounted device moves in the augmented reality space in a direction approaching the virtual display interface, the dimensions of the virtual display interface are reduced.

[0059] When the head-mounted device is moved in the augmented reality space away from the virtual display interface, the virtual display interface is enlarged in size.

[0060] To avoid frequent adjustment of the dimensions of the virtual display interface, the dimensions of the display interface may be adjusted when the distance of movement in a preset direction is greater than a preset distance. For example, the preset distance may be set to 2 meters. Assuming the initial position is 3 meters, the initial dimensions of the virtual display interface are as shown in FIG. 4. When the head-mounted device moves 2.5 meters toward the virtual display interface, the dimensions of the virtual display interface after the reduction are specifically tangent to 30° in the horizontal direction and tangent to 27.5° in the vertical direction, as shown in FIG. 5. When the head-mounted device moves 2 meters away from the virtual display interface, the dimensions of the virtual display interface after the reduction are specifically 10×tangent to 30° and 10×tangent to 27.5° in the vertical direction, as shown in FIG. 6.

[0061] To avoid causing the user to feel dazzled or the like by adjusting the dimensions of the virtual display interface while the user is moving, the dimensions of the virtual display interface may be adjusted after detecting that the head-mounted device is stationary, and may not be adjusted while the head-mounted device is moving.

[0062] The head-mounted device used in the embodiments of the present disclosure is an augmented reality device based on 6dof (degree of freedom) technology. The 6dof augmented reality device may be glasses or other reasonable devices, and can detect not only changes in the viewing angle due to head rotation but also changes in up / down, front / back, left / right displacement due to body movement. Therefore, the embodiments of the present disclosure not only maximize the user's eye comfort, but also enable more comfortable direction changes and improve the user experience.

[0063] A method for displaying a virtual display interface in an augmented reality space according to an embodiment of the present disclosure includes first obtaining map information of the real space using an image capturing device, then generating an augmented reality space using a rendering engine based on the map information of the real space, and finally determining a target position of the virtual display interface in the augmented reality space and displaying the virtual display interface at the target position. Since the dimensions of the virtual display interface are related to the target position where the virtual display interface is located and the user's visual range, the dimensions of the virtual display interface can be determined based on the target position where the virtual display interface is located and the user's visual range, thereby solving the problem of users' poor viewing experience of the virtual display interface.
