摘要：This paper describes an efficient method for dense matching of two or three images. After some investigations in different similarity measures we propose a modification of Semi-Global Matching, which uses a simple energy function that implies piecewise smoothness but no ordering and gives promising results in practice. Our improvements include a symmetric and hierarchical matching strategy and allow an efficient generalization of the stereo matching problem to trinocular surface reconstruction. Finally, we present results for synthetic and for real images
