Embodiment Construction
[0073] As mentioned above, in order to realize multi-degree-of-freedom images at present, a large amount of data calculation is required. For example, the method of expressing multi-degree-of-freedom images through point clouds requires a very large amount of storage because point clouds express and store the three-dimensional positions and pixel information of all points in space. Correspondingly, in the image reconstruction process, It also requires a very large amount of data calculation. If the above image reconstruction method is used to perform image reconstruction on the cloud, it will cause a very large processing pressure on the cloud reconstruction equipment. If the image reconstruction is performed on the terminal, the terminal has limited processing capacity and it is difficult to handle such a large amount of data. In addition, there is currently no good standard and industrial software and hardware support for point cloud compression, which is not conducive to po...

The invention discloses an image reconstruction method, system and equipment and a computer readable storage medium. The method comprises the steps that an image combination of a multi-angle free viewangle, parameter data of the image combination and virtual viewpoint position information based on user interaction are acquired, and the image combination comprises multiple groups of texture imagesand depth images which are synchronous in multiple angles and have corresponding relations; according to the virtual viewpoint position information and the parameter data of the image combination, atexture map and a depth map of a corresponding group in the image combination at the moment of user interaction are selected according to a preset rule; and based on the virtual viewpoint position information and the parameter data corresponding to the texture map and the depth map of the corresponding group in the user interaction moment image combination, combined rendering is carried out on thetexture map and the depth map of the corresponding group in the selected user interaction moment image combination to obtain a reconstructed image corresponding to the virtual viewpoint position at the user interaction moment. By adopting the scheme, the data operation amount in the image reconstruction process can be reduced.
Description
technical field [0001] The implementation of the present invention relates to the technical field of image processing, and in particular to an image reconstruction method, system, device, and computer-readable storage medium. Background technique [0002] With the continuous development of Internet technology, more and more video platforms continue to improve the user's visual experience by providing clearer or watching videos with higher fluency. [0003] However, for videos with a strong sense of on-site experience, such as images of a basketball game, users often can only watch the game through one viewpoint during the viewing process, and cannot freely switch viewpoints to watch the game at different viewpoints. or the course of the game. [0004] 6 degrees of freedom (6 Degree of Freedom, 6DoF) technology is a technology to provide high-degree-of-freedom viewing experience. Users can adjust the viewing angle through interactive means during viewing, and watch from the ...
