Filtering system, method and device based on depth map reconstruction view and storage medium

The invention provides a filtering method, system and device based on a depth map reconstruction view, and a storage medium. The method comprises the following steps: obtaining a depth map based on a left viewpoint original image and a right viewpoint original image; converting each effective depth value in the depth map into parallax information of a corresponding pixel, and generating an analog image of a second viewpoint based on the original image of the first viewpoint and the parallax information; obtaining an error value of each pixel according to the analog image of the second viewpoint and the original image of the second viewpoint; and generating an error threshold according to the error value, collecting pixels of which the error value is smaller than the error threshold to generate a to-be-filtered pixel set, and filtering an effective depth value corresponding to the to-be-filtered pixel set in the depth map. According to the invention, the simulation image of another viewpoint can be generated t
