Title:
VIRTUAL VIEWPOINT DEPTH MAP PROCESSING METHOD, DEVICE, AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/116397
Kind Code:
A1
Abstract:
Disclosed in the present application are a virtual viewpoint depth map processing method, device, and apparatus, and a storage medium. In the present application, a virtual viewpoint depth map is obtained by forwardly mapping a reference viewpoint depth map corresponding to a preset reference viewpoint to the position of a virtual viewpoint; the virtual viewpoint depth map is subjected to smoothing processing by using a preset filter method, such that edge information of the depth map is retained; the smoothed virtual viewpoint depth map is inversely mapped to the position of the preset reference viewpoint to synthesize virtual viewpoint texture maps based on different preset reference viewpoints; the virtual viewpoint texture maps are subjected to weighted fusion, and the fused virtual viewpoint texture map is subjected to hole filling processing and foreground edge filtering processing, thereby improving the quality of the virtual viewpoint depth map.
