Abstract
The disclosure is directed to methods, apparatuses, and devices for synthesizing virtual viewpoint images that are configured for acquiring an original image set, performing stereo matching to original images to obtain a first disparity map set, performing optimization processing to each first disparity map in the first disparity map set to obtain a second disparity map set, determining whether each second disparity map in the second disparity map set has a third disparity map with deep tomography to obtain a first determination result, if the first determination result indicates existence of the third disparity map, segmenting a portion with deep tomography to obtain a corresponding foreground disparity map and a corresponding background disparity map, mapping the second disparity map without deep tomography, the foreground disparity map, the background disparity map, and the portion without deep tomography in the third disparity map according to a first virtual viewpoint to obtain a first virtual viewpoint image set, and fusing first virtual viewpoint images to obtain a to-be-synthesized viewpoint image. Adoption of the methods, apparatuses, and devices for synthesizing virtual v…
