Problems solved by technology
When outputting video images to various projection surfaces or display screens for playback, it is necessary to cut a complete video image, and then project each cut video image onto each screen, but due to the lack of combination during video cutting The physical specifications (size, shape, etc.) of each display screen make it impossible to reasonably allocate the proportion of the video screen to be played on each display screen during cutting, which often leads to the problem of deformation of the screen on the screen

The invention discloses a video playing method and device based on a CAVE space and a storage medium. The method comprises the steps: acquiring position information of a user viewpoint, position information of all display screens in the CAVE space and shape information of all the display screens; constructing a panoramic video spherical playing model, mapping a user viewpoint into a sphere center,and then constructing a mapping surface corresponding to each display screen in the panoramic video spherical playing model; projecting all the mapping surfaces to the spherical surface of the panoramic video spherical playing model to obtain a video picture area corresponding to each display screen; and segmenting the panoramic video picture according to the video picture area to obtain a to-be-played video picture corresponding to each display screen, so that each display screen plays the corresponding to-be-played video picture. By implementing the embodiment of the invention, the problemof deformation of the output picture of each display screen in the existing CAVE space can be reduced, and the user experience is improved.
Description
technical field [0001] The present invention relates to the technical field of video playing, in particular to a video playing method, device and storage medium based on a CAVE space. Background technique [0002] CAVE is a projection-based virtual reality system. It generally consists of five projection surfaces (upper, lower, left, right, and front) surrounding the user. The five projection surfaces form a three-dimensional space structure. Projected onto 5 projection surfaces, creating impact and shock from all directions, so that users can obtain a deeply immersive visual experience. When outputting video images to various projection surfaces or display screens for playback, it is necessary to cut a complete video image, and then project each cut video image onto each screen, but due to the lack of combination during video cutting The physical specifications (size, shape, etc.) of each display screen make it impossible to reasonably allocate the proportion of the video ...
