Regional uniformity-based stereo matching optimization method, apparatus and device, and medium

The invention provides a stereo matching optimization method and device based on region uniformity, equipment and a medium, and the method comprises the steps: determining a local transformation window with a to-be-matched pixel as a central pixel, carrying out the region segmentation of the local transformation window according to the position of the central pixel, and obtaining each sub-region; calculating the region uniformity of each sub-region, and calculating an equivalent center value of a local transformation window according to pixel information in the sub-region corresponding to the maximum and minimum region uniformity; and optimizing a cost calculation link of the AD-Census stereo matching based on the equivalent center value to obtain optimized stereo matching. According to the stereo matching optimization method based on the region uniformity, the cost is calculated in combination with the region uniformity, so that optimized stereo matching does not depend on a center pixel, the cost value can
