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. 本发明涉及图像处理相关技术领域，具体涉及一种基于改进双目匹配SAD算法的三维重建方法及装置。其中，所述基于改进双目匹配SAD算法的三维重建方法包括：获取原始图片；原始图片包括对应的第一图片和第二图片；基于所述原始图片，通过改进的SAD算法，获得初始视差图；其中，所述改进的SAD算法在初始视差图生成过程中偏重于两张图片的图像块中心像
