Depth reconstruction system for structured light camera

The invention provides a depth reconstruction system for a structured light camera, and the system comprises an image obtaining module which is used for obtaining a plurality of images continuously collected in a target region in continuous time, and the images are images of a plurality of target objects stored on a material carrier; the movement judgment module is used for judging whether the target object moves in the continuous time or not according to the multiple images and returning to the image acquisition module when the target object moves; and the depth reconstruction module is used for performing depth reconstruction according to the plurality of images or the target image to generate a depth image of the target area. When a sorting robot sorts a target object out of a material carrier every time, images of a plurality of target objects stored on the material carrier are collected in continuous time through a depth camera, and whether the target object moves due to collapse in the time or not is ju
