Embodiment Construction

[0073] As mentioned above, in order to realize a multi-DOF image at present, a large amount of data computation is required. For example, in the way of expressing multi-degree-of-freedom images through point clouds, since point clouds express and store the three-dimensional positions and pixel information of all points in space, a very large amount of storage is required. Correspondingly, in the process of image reconstruction, It also requires a very large amount of data operations. If image reconstruction is performed in the cloud using the above image reconstruction method, it will cause a great deal of processing pressure to the cloud reconstruction device. If the image reconstruction is performed on the terminal, the processing capability of the terminal is limited, and it is difficult to process such a large amount of data. In addition, there is no good standard and industrial software and hardware support for point cloud compression at present, which is not conducive to...

Abstract

An image reconstruction method, system, device, and computer-readable storage medium, the method includes: acquiring a multi-angle free viewing angle image combination, parameter data of the image combination, and virtual viewpoint position information based on user interaction, wherein the The image combination includes multiple sets of texture maps and depth maps that are synchronized from multiple angles and have a corresponding relationship; according to the virtual viewpoint position information and the parameter data of the image combination, the corresponding group in the image combination at the moment of user interaction is selected according to preset rules. texture map and depth map; based on the virtual viewpoint position information and the parameter data corresponding to the texture map and depth map of the corresponding group in the image combination at the user interaction time, the texture map and depth map of the corresponding group in the selected user interaction time image combination The images are combined and rendered to obtain a reconstructed image corresponding to the position of the virtual viewpoint at the moment of user interaction. Using the above solution can reduce the amount of data operation in the image reconstruction process.

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 higher definition or watching videos with higher fluency. [0003] However, for videos with a strong sense of on-site experience, such as an image of a basketball game, users often can only watch the game from one viewpoint during the viewing process, and cannot freely switch the viewpoint by themselves to watch the game at different viewpoints. or game process. [0004] 6 Degree of Freedom (6DoF) technology is a technology to provide a high degree of freedom viewing experience. Users can adjust the viewing angle through interactive means during viewing, and watch from the fre...
