Summary: | The invention relates to the related technical field of image processing, in particular to a three-dimensional reconstruction method and device based on an improved binocular matching SAD algorithm. The three-dimensional reconstruction method based on the improved binocular matching SAD algorithm comprises the steps: acquiring an original picture; wherein the original picture comprises a first picture and a second picture which correspond to each other; based on the original picture, obtaining an initial disparity map through an improved SAD algorithm; wherein the improved SAD algorithm focuses on the matching precision of the central pixels of the image blocks of the two images in the initial disparity map generation process; and filling a cavity of the initial disparity map to optimize the initial disparity map to obtain a final disparity map.
