By using a panoramic camera or rendering technology, panoramic images or videos can be captured or generated, allowing users to experience the virtual environment from a 360-degree perspective. It is also applied to the virtual engine space as in this application, but this technology is to construct a virtual scene and transmit it to a VR head-mounted display after rendering.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0049] It should also be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0050] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0051] In order to understand the present invention more clearly, the technical terms involved in the present invention are explained as follows:

[0052] Zero disparity plane: refers to the area on the plane where the images captured by the left and right cameras (also called binocular cameras) in a stereo camera have no disparity. When objects on this plane are presented in a stereo image, there is no stereoscopic visual dislocation. This plane is usually the area where the audience feels most comfortable. Figure 6 As shown, in Figure 6 The materials captured by the two cameras on the middle red convergence plane completely overlap, with no aberration, and the red plane is the zero aberration plane.

[0053] Interpupillary distance: refers to the distance between the left and right cameras in a stereo camera. When creating stereo images, the expected interpupillary distance is generally set to be close to the interpupillary distance of the human eye in order to simulate a true 3D visual effect.

[0054] Curved screen: refers to a curved screen used to display images or videos. This type of screen is usually used to provide a wider field of view and a more immersive experience. In the process of creating a 3D virtual stereo camera, the curved screen is used as a reference to determine the placement and viewing angle of the camera.

[0055] The present invention is described below by means of specific embodiments.

[0056] like Figure 1 As shown, an embodiment of the present invention provides a method for creating a three-dimensional virtual stereo camera, including the following steps: S10-S30.

[0057] S10, obtaining curved screen parameters and audience viewpoint position.

[0058] The curved screen parameters and the audience's viewpoint position are data from actual scenes and can be obtained from actual scene measurements. The curved screen parameters include the curved screen radius, curved screen angle, and curved screen height, which can all be obtained from actual scenes.

[0059] S20, creating a curved screen model according to the curved screen parameters and determining the viewpoint position of the virtual stereo camera.

[0060] By creating an accurate curved screen model and determining the viewpoint position of the virtual stereo camera, it can be ensured that the viewing angle of the virtual stereo camera can cover the entire curved screen.

[0061] In one embodiment, step S20 specifically includes the following steps: S201 - S204 .

[0062] S201, dividing the width of the curved screen into several equal parts.

[0063] The entire curved screen is divided into several equal areas, for example, three equal areas, four equal areas, etc., so as to set a virtual stereo camera in each area. Specifically, according to the total width of the curved screen and the number of cameras required, the screen width is evenly divided into several equal areas. The width of each equal area should be equal to ensure that the area covered by each camera is consistent.

[0064] S202: Set a virtual stereo camera in each equally divided area.

[0065] A virtual stereo camera is set in each equally divided area. The viewing angle of each camera should be aligned with the width of its corresponding area to ensure that each camera can cover its corresponding equally divided area and the coverage range of all cameras can be combined to fully cover the entire screen.

[0066] S203: When the camera viewing angle width of the virtual stereo camera is aligned with the width of the corresponding equally divided area, the placement position of the virtual stereo camera is determined.

[0067] Adjust the position of each virtual stereo camera so that the width of its field of view is exactly aligned with the width of the region.

[0068] S204: Use the placement position as the viewpoint position of the virtual stereo camera, and place the virtual stereo camera at the viewpoint position.

[0069] The previously determined camera placement position is used as the viewpoint position of each camera, and the camera is actually placed at the position, ensuring that the camera's orientation and angle are correct to cover the corresponding equally divided area.

[0070] For steps S201-S204, it can be ensured that the position and viewing angle of each virtual stereo camera are accurately adjusted so as to completely cover the curved screen. Figure 7 As shown, the curved screen is divided into three equal areas, each of which is equipped with a virtual stereo camera. Figure 7 It is the state when the camera viewing angle widths of the three virtual stereo cameras are aligned with the widths of the corresponding equally divided areas.

[0071] S30. Establishing a relationship between pupil distance and zero aberration surface based on the curved screen model.

[0072] In one embodiment, step S30 specifically includes the following steps: S301 - S302 .

[0073] S301 , setting the desired pupil distance of two cameras of the virtual stereo camera.

[0074] The expected pupil distance can be set according to actual conditions. Generally, the expected pupil distance can be set with reference to the pupil distance of the human eye, that is, the expected pupil distance between the left and right cameras of the virtual stereo camera is set to match the pupil distance of the human eye.

[0075] S302: Calculate zero-disparity surfaces of two cameras of the virtual stereo camera according to the expected pupil distance.

[0076] The calculation formula is as follows:

[0077] Where DE is the value of the zero aberration surface, AF is the pupil distance, AC is the equivalent focal length, and BG is the film width.

[0078] For a clearer understanding of the above formula, please refer to Figure 8 , Figure 8 In the figure, △ABC and △ADE are similar triangles, the equivalent focal length = AC, and the value of the zero aberration surface translateZ = Tz (ie DE).

[0079] So we have:

[0080] It should be noted that in actual applications, the units need to be converted and converted into centimeters for calculation. 2.54 is the conversion coefficient from inches to centimeters. At the same time, 1.2 is a coefficient, which is a parameter value that meets the comfortable stereo effect obtained through repeated experimental tests. With the addition of this coefficient, the actual stereo experience will be more comfortable. The last division in the formula is 100 to convert from centimeters to meters for actual reference.

[0081] By associating the pupil distance and the zero aberration plane, when one of the variables is known, the other variable can be obtained. In specific applications, the producer does not need to know the appropriate pupil distance at different distances, but only needs to select the subject to be expressed, which facilitates the producer's adjustment and avoids the problem of the pupil distance being too large when the subject is at a certain distance, resulting in an uncomfortable three-dimensional effect.

[0082] like Figure 2 As shown, in one embodiment, after step S30, the following steps are further included: S301-S302.

[0083] S301, during simulation shooting, obtaining parameters of a real stereo camera;

[0084] S302: Calculate the viewpoint position of the real stereo camera according to the parameters of the real stereo camera.

[0085] For S301-S302, when performing simulated shooting, it is necessary to use it as a real-shot camera. It is necessary to obtain the film width and equivalent focal length of the real stereo camera, and then use the formula to calculate the viewpoint position of the real stereo camera, and adjust the real stereo camera to the viewpoint position. The calculation formula is as follows:

[0086] Wherein, OE is the movable range of the viewpoint position, E is the viewpoint position, CD is the film width, AB is the chord length of the curved screen, FG is the chord height of the curved screen, and OF is the radius of the curved screen.

[0087] For a clearer understanding of the above formula, please refer to Fig. 9 , Fig. 9 AFB is the arc screen, E is the camera viewpoint, O is the center of the arc screen, AB is the arc screen chord length, FG is the arc screen chord height, CD is the camera film width, and EH is the equivalent focal length. △ABE and △CDE are similar triangles.

[0088] Based on this formula, the viewpoint That is, OE represents the distance the viewpoint should move.

[0089] By utilizing the parameters of the real-life camera and simulating real-life shooting based on the above formula, shooting is completed in a virtual three-dimensional environment and all-round data measurement is performed, including data such as the height of the camera from the ground, the distance from the camera to the object, and the height difference between the object and the camera.

[0090] The embodiment of the present invention further provides a 3D virtual stereo camera creation device, which is used to execute the steps in any embodiment of the above 3D virtual stereo camera creation method. Figure 3 , Figure 3 A schematic block diagram of a 3D virtual stereo camera creation device 100 provided in an embodiment of the present application is shown, and the 3D virtual stereo camera creation device 100 specifically includes a first acquisition unit 110, a creation unit 120, and an association unit 130. The first acquisition unit 110 is used to acquire arc screen parameters and the viewer's viewpoint position. The creation unit 120 is used to create an arc screen model according to the arc screen parameters and determine the viewpoint position of the virtual stereo camera. The association unit 130 is used to establish an association between the pupil distance and the zero aberration surface based on the arc screen model.

[0091] In one embodiment, the creation unit 120 includes a division module, a setting module, an alignment module, and an adjustment module. The division module is used to divide the width of the arc screen into a number of equal parts. The setting module is used to set a virtual stereo camera in each equal area. The alignment module is used to determine the placement position of the virtual stereo camera when the camera viewing angle width of the virtual stereo camera is aligned with the width of the corresponding equal area. The adjustment module is used to use the placement position as the viewpoint position of the virtual stereo camera and place the virtual stereo camera to the viewpoint position.

[0092] In one embodiment, the association unit 130 includes a setting module and a calculation module. The setting module is used to set the desired pupil distance of the two cameras of the virtual stereo camera. The calculation module is used to calculate the zero disparity surface of the two cameras of the virtual stereo camera according to the desired pupil distance.

[0093] like Figure 4 As shown, in one embodiment, the 3D virtual stereo camera creation device 100 further includes a second acquisition unit 140 and a calculation unit 150. The second acquisition unit 140 is used to acquire the parameters of the real stereo camera during the simulation shooting. The calculation unit 150 is used to calculate the viewpoint position of the real stereo camera according to the parameters of the real stereo camera.
