Document Type and Number:
WIPO Patent Application WO/2022/002181
Kind Code:
A1
Abstract:
A free viewpoint video reconstruction method and playing processing method, and a device and a storage medium. The video reconstruction method comprises: acquiring a spliced image of a plurality of frame moments, wherein the spliced image comprises texture maps of a plurality of synchronous viewing angles, and first depth maps of the corresponding viewing angles, and the resolution of the first depth maps is less than the resolution of the texture maps; separating the texture maps and the first depth maps in the spliced image; upsampling the first depth maps on the basis of the resolution of the corresponding texture maps in the spliced image to obtain second depth maps; and on the basis of the texture maps of the plurality of synchronous viewing angles in the spliced image, and the second depth maps of the corresponding viewing angles, performing reconstruction according to position information of a virtual viewpoint and parameter data corresponding to the spliced image, so as to obtain an image of the virtual viewpoint. By using the solution, the definition of a free viewpoint image obtained by means of reconstruction can be improved.
