Depth map processing method and device and storage medium

According to the depth map processing method and device and the storage medium provided by the embodiment of the invention, the depth map and the color map registered with the depth map are acquired, target detection is performed on the color map, region division is performed on the color map based on the detected contour of the target, the contour region is obtained, the cavity region is extracted from the depth map, and the depth map processing efficiency is improved. And on the basis of a registration relationship between the depth image and the color image, intersection of the depth image and the color image subjected to region division is solved, and a sub-region intersected with the contour region in the cavity region is obtained. Wherein the sub-regions are the sub-regions of the cavity region and the contour region, the sub-regions are the sub-regions of the sub-regions, and the sub-regions can be effectively distinguished according to the sub-regions. Therefore, according to the embodiment, the sub-r
