description The invention discloses a large-scale target three-dimensional reconstruction method and system based on binocular vision. The three-dimensional reconstruction method comprises the following steps: obtaining binocular images of a target at different visual angles; performing dual-threshold judgment on pixel information in the binocular image, positioning an information missing position, and performing information enhancement on missing pixels by using a tensor completion algorithm; extracting a target in the binocular image after information enhancement; and carrying out stereo matching on the binocular image of the target, calculating local point cloud information according to the obtained depth map, and restoring the overall three-dimensional structure of the target through point cloud splicing. The binocular vision-based three-dimensional reconstruction technology can effectively overcome the influence of environment change on the reconstruction effect, the tensor completion technology is utilized to enhan
