[0002] With the development of LED display, the 3D display of LED cube screen is gradually needed by the majority of users.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0021] Figure 1 It is a flow chart of a three-dimensional image display method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to a scene of controlling a cube to display a 3D image. The method can be executed by a three-dimensional image display device, which can be implemented by software and / or hardware.

[0022] like Figure 1 As shown, the three-dimensional picture display method includes the following steps:

[0023] S110 , obtaining object coordinates of at least one target object at every preset update duration, and determining target viewing angle coordinates according to the object coordinates of the target object.

[0024] The target cubic screen may be a cubic screen that needs to manage the screen display angle. Optionally, the target cubic screen may be an LED cubic screen. The 3D screen may be displayed from a variety of angles. The preset update duration may be a preset duration for updating the screen display angle of the target cubic screen. Specifically, the preset update duration may be manually set.

[0025] The target object may be an object that observes the target cube screen. The object coordinates may be the coordinates at which the target object is located. Specifically, the object coordinates may be three-dimensional coordinates of the target object. For example, a recognition device may be installed on one side of the target cube to recognize the target object within the detection range at each preset update time interval, determine the object coordinates of each target object, and send the object coordinates of each target object to the device of the embodiment of the present invention.

[0026] Furthermore, the target viewing angle coordinates may be reference coordinates for the target cubic screen to display the image. That is, the target cubic screen needs to adjust the angle of the displayed image so that the observer can observe the complete 3D image from the target viewing angle coordinates. Specifically, the object coordinates of the target object may be analyzed to determine a coordinate with the best observation effect relative to multiple target objects, and the coordinate is used as the target viewing angle coordinate.

[0027] S120: Determine a target display section according to the target viewing angle coordinates and the center point coordinates of the target cubic screen.

[0028] The target display section may be a reference section for the target cubic screen to display the image. Specifically, the target viewing angle coordinates and the center point coordinates of the target cubic screen may be connected to obtain a target extension line, and a section perpendicular to the target extension line may be used as the target display section. By determining the target display section, it is convenient to subsequently determine the rotation angle of the display image based on the target display section.

[0029] S130: Based on the target display slice, control the target cube screen to display a target three-dimensional image.

[0030] The target three-dimensional picture may be a picture displayed on the target cubic screen. Specifically, the display angle of the target three-dimensional picture may be adjusted so that the best display section of the target three-dimensional picture coincides with the target display section. The best display section of the target three-dimensional picture may be a manually set section, through which the 3D effect of the target three-dimensional picture may be fully observed.

[0031] The technical solution provided by the embodiment of the present invention obtains the object coordinates of at least one target object by presetting the update duration at each interval, determines the target viewing angle coordinates according to the object coordinates of the target object; determines the target display section according to the target viewing angle coordinates and the center point coordinates of the target cube screen; and controls the target cube screen to display the target three-dimensional image based on the target display section. The technical solution of the embodiment of the present invention solves the problem of the fixed orientation angle of the image display in the existing three-dimensional image display technology, and can realize that the screen can dynamically adjust the viewing angle according to the position of the observer, so that the observer can see the 3D effect at different angles, improving the viewing experience.

[0032] Figure 2 It is another flow chart of a three-dimensional picture display method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to a scene of controlling a cube to display a 3D picture. Based on the above embodiment, this embodiment further explains how to determine the target viewing angle coordinates according to the object coordinates of the target object; how to determine the target display section according to the target viewing angle coordinates and the center point coordinates of the target cube screen; and how to control the target cube screen to display the target three-dimensional picture based on the target display section. The device can be implemented by software and / or hardware and integrated in a computer device with application development function.

[0033] like Figure 2 As shown, the three-dimensional picture display method includes the following steps:

[0034] S210 , obtaining object coordinates of at least one target object at every preset update time interval.

[0035] The target cubic screen may be a cubic screen that needs to manage the screen display angle. Optionally, the target cubic screen may be an LED cubic screen. The 3D screen may be displayed from a variety of angles. The preset update duration may be a preset duration for updating the screen display angle of the target cubic screen. Specifically, the preset update duration may be manually set.

[0036] Further, the target object may be an object that observes the target cube screen. The object coordinates may be the coordinates at which the target object is located. Specifically, the object coordinates may be the three-dimensional coordinates of the target object. For example, a recognition device may be installed on one side of the target cube to recognize the target object within the detection range at each preset update time interval, determine the object coordinates of each target object, and send the object coordinates of each target object to the device of the embodiment of the present invention.

[0037] S220 . For each target object, determine an observation distance between the target object and the target cube screen according to the object coordinates of the target object, and determine an observation priority of the target object according to the observation distance.

[0038] The distance between the target object and the target cube can be calculated according to the coordinates between the two, and the calculated distance is used as the observation distance of the target object. The observation priority can be a level of evaluating the target object from the observation angle.

[0039] Optionally, determining the observation priority of the target object based on the observation distance includes: determining the observation state of the target object based on the current observation distance and the last observation distance of the target object, and determining the state priority of the target object based on the observation state; comparing the observation distance with at least one preset distance threshold, and determining the distance priority of the target object based on the comparison result; determining the observation priority of the target object based on the observation priority and the distance priority.

[0040] Among them, the observation state may include a stationary state, a close state, and a far state. Specifically, the current observation distance of the target object and the last observation distance may be compared. If the difference between the two is within a preset range, it can be determined that the observation state of the target object is a stationary state. If the difference between the two is not within the preset range, and the current observation distance is greater than the last observation distance, it can be determined that the observation state of the target object is a far state. If the difference between the two is not within the preset range, and the current observation distance is less than the last observation distance, it can be determined that the observation state of the target object is a close state.

[0041] Furthermore, the distance priority may be a level for evaluating the target object from the perspective of observation distance. Specifically, the observation distance may be compared with at least one preset distance threshold, and the distance priority of the target object may be determined based on the comparison result. Exemplarily, the distance priority may include an optimal observation level and an observable level. For example, if the size of the target cube screen is 100cm*100cm*100cm and the resolution is 1920*1080, then the observation range of the optimal distance device is considered to be within 5m, and the observable range is within 5m-10m.

[0042] S230 , comparing the observation priority of each target object, and determining the target viewing angle coordinates according to the object coordinates of at least one target object with the highest observation priority.

[0043] The target viewing angle coordinates may be reference coordinates for the target cubic screen to display the picture, that is, the target cubic screen needs to adjust the angle of the displayed picture so that the observer can observe the complete 3D picture from the target viewing angle coordinates.

[0044] Optionally, the observation priority of each target object is compared, and the target viewing angle coordinates are determined based on the object coordinates of at least one target object with the highest observation priority, including: when the number of target objects with the highest priority is one, the object coordinates of the target object with the highest priority are used as the target viewing angle coordinates; when the number of target objects with the highest priority is multiple, the mean coordinates of the object coordinates of the multiple target objects with the highest priority are determined, and the mean coordinates are used as the target viewing angle coordinates.

[0045] The mean coordinate is the average value of multiple coordinates. When there are multiple target objects with the highest priority, the object coordinates of the multiple target objects with the highest priority can be averaged and the obtained average value is used as the target viewing angle coordinate.

[0046] Exemplarily, determining the target viewing angle coordinates may include the following steps:

[0047] 1. Statistics are collected every 500ms (the collected observer data is encapsulated into a model)

[0048] 2. Calculate the best observation range and observable range based on the size and resolution of the device. (For example, if the device size is 100cm*100cm*100cm and the resolution is 1920*1080, then the best observation range of the device is 5m, 10m is the observable range, and anything beyond 10m or within 20cm is considered unobservable)

[0049] 3. Then, the observer's observation priority is calculated according to the distance of the observer (ie, the target object) from the device and the observer's state.

[0050] 4. Calculate the target viewing angle coordinates based on the observer’s priority.

[0051] Statistical process:

[0052] 1. Encapsulate the counted observers into a model. The model information includes:

[0053] ①Unique identification

[0054] ② Three-dimensional coordinates relative to the device

[0055] ③Specific distance relative to the device

[0056] ④ The state of the observer

[0057] ⑤ Priority

[0058] 2. When counting, if the distance between the observer and the device is shortened compared to the last time, the observer is considered to be approaching, otherwise it is considered to be moving away. If there is no change, it is considered to be observing (this process can be processed according to the speed and displacement distance, and the observer's state is counted as being in a relatively stable state as much as possible)

[0059] 3. If the observer is out of the observable range, remove the observer data.

[0060] 4. Priority division (the same level is distinguished by the distance from the device, the closer the distance, the higher the priority):

[0061] ① The best observation range and the priority is first in a static state

[0062] ② Best observation range, and close to the state with the second priority

[0063] ③ Observable range, and in close state, priority 3

[0064] ④ Observable range and in a stationary state. Priority 4

[0065] ⑤ Best observation range, and in a far away state, the fifth priority

[0066] ⑥ Observable range, and in a distant state, priority 6

[0067] 5. The coordinates of the observer with the highest priority are taken as the target viewing angle coordinates (if the priorities are the same, the average of the three-dimensional coordinates of observers with the same level of priority is taken as the target viewing angle coordinates).

[0068] S240: Determine a target display section according to the target viewing angle coordinates and the center point coordinates of the target cubic screen.

[0069] The target display section may be a reference section for the target cubic screen to display the image. Specifically, the target viewing angle coordinates and the center point coordinates of the target cubic screen may be connected to obtain a target extension line, and a section perpendicular to the target extension line may be used as the target display section. By determining the target display section, it is convenient to subsequently determine the rotation angle of the display image based on the target display section.

[0070] S250: Based on the target display slice, control the target cube screen to display a target three-dimensional image.

[0071] The target three-dimensional picture may be a picture displayed on the target cubic screen. Specifically, the display angle of the target three-dimensional picture may be adjusted so that the best display section of the target three-dimensional picture coincides with the target display section. The best display section of the target three-dimensional picture may be a manually set section, through which the 3D effect of the target three-dimensional picture may be fully observed.

[0072] Optionally, based on the target display section, controlling the target cubic screen to display the target three-dimensional image includes: determining the target rotation angle according to the target display section and the current display section of the target cubic screen; and based on the target rotation angle, controlling the target cubic screen to rotate and display the target three-dimensional image.

[0073] The target rotation angle may be an adjustment angle of the target three-dimensional image. The target rotation angle may be a three-dimensional angle. Specifically, the angle between the target display section and the current display section of the target cube screen may be used as the target rotation angle. Further, the current display angle of the target three-dimensional image may be rotated by the target rotation angle for display.

[0074] Optionally, controlling the target cubic screen to rotate the target three-dimensional image for display includes: for each two-dimensional image of the target three-dimensional image, rotating each two-dimensional image by a target rotation angle for rendering and display. Rendering and displaying can be understood as displaying after rendering processing. Rendering processing includes but is not limited to color adjustment, saturation adjustment, and brightness adjustment.

[0075] For example, Figure 3 This is a schematic diagram of a target cubic screen provided by an embodiment of the present invention. The default screen center is the origin, and the size of the cubic screen is 100cm*100cm*100cm, so the coordinates of the eight vertices can be known (assuming that our screen is now placed like this, the viewing angle coordinates are the vertical sections determined by the viewing angle after the extension line of the line connecting the center point and C1 at this time are B, B1, D, D1).

[0076] In order to better understand the technical solution provided by the present invention, the following is an introduction to the specific embodiment steps:

[0077] 1. Collect data

[0078] ① By connecting the positioning device (infrared positioning sensor, binocular camera and other modules, assuming it is installed at C1) to the top of the screen or other fixed positions.

[0079] ②500ms is used to collect valid data from the positioning device (the observer's effective three-dimensional coordinates x, y, z relative to the center of the device. If there are multiple observers, there will be multiple observation coordinates. The specific interference processing details are described in the implementation method).

[0080] 2. Data Processing

[0081] ① After obtaining the viewer's viewing angle coordinates (x, y, z), draw a line to the center of the cubic screen and determine a vertical section. If the observer's coordinates are on the extension line of the origin and D1 at this time, it can be determined that the cubic screen section at this time is A, A1, C1, C. (The coordinates obtained at different installation locations need to be offset according to the coordinates of the installation location relative to the center of the screen).

[0082] ② By intersecting this section with the default 3D viewing angle sections B, B1, D, and D1 of the screen, it is possible to calculate in the cube that the angle between the two sections is +90°.

[0083] ③ After determining the angle, just rotate the original sections B, B1, D, D1 by +90 degrees so that they can overlap with sections A, A1, C1, C, thereby achieving the purpose of 3D perspective rotation.

[0084] 3. Dynamically render 3D images (by cutting each face of the actual image seen by the observer into 2D planes, and continuously rendering each frame of the image to each face corresponding to the cubic screen).

[0085] For example, Figure 4 FIG. 1 is a schematic diagram of rendering a 3D image provided by an embodiment of the present invention. Figure 4 As shown, the red sphere in Figure (1) represents the viewpoint A where the observer is located. The rendering at this time is based on the viewpoint A, and the yellow sphere represents the viewpoint B after the observer moves. When the observer is in viewpoint A, the image he actually sees is Figure (2) (a complete 3D image), and when the observer is in viewpoint B, the image he actually sees is Figure (3). Therefore, the observer cannot observe the complete 3D image when he is in viewpoint B.

[0086] The technical solution provided by the embodiment of the present invention obtains the object coordinates of at least one target object by presetting the update duration at each interval; for each target object, determines the observation distance between the target object and the target cube screen according to the object coordinates of the target object, and determines the observation priority of the target object according to the observation distance; compares the observation priority of each target object, and determines the target viewing angle coordinates according to the object coordinates of at least one target object with the highest observation priority; determines the target display section according to the target viewing angle coordinates and the center point coordinates of the target cube screen; based on the target display section, controls the target cube screen to display the target three-dimensional picture. The technical solution of the embodiment of the present invention solves the problem of the fixed orientation angle of the picture display in the existing three-dimensional picture display technology, and can realize that the screen can dynamically adjust the viewing angle according to the position of the observer, so that the observer can see the 3D effect at different angles, improving the viewing experience.

[0087] Figure 5 It is a structural schematic diagram of a three-dimensional image display device provided by an embodiment of the present invention. The embodiment of the present invention can be applied to a scene of controlling a cube to display a 3D image. The device can be implemented by software and / or hardware and integrated into a computer device with application development function.

[0090] The technical solution provided by the embodiment of the present invention obtains the object coordinates of at least one target object by presetting the update duration at each interval, determines the target viewing angle coordinates according to the object coordinates of the target object; determines the target display section according to the target viewing angle coordinates and the center point coordinates of the target cube screen; and controls the target cube screen to display the target three-dimensional image based on the target display section.
