3D Reconstruction Based on a Fast Area-based Stereo Matching Algorithm
Hongwei Gao, Chengdong Wu, Bin Li · 2006
According to the parallel binocular vision system, a connotative constraint was proved by geometry theory in this paper. That is for any space point projected into two images, along the horizontal direction in image coordinate, there always exists U1> U2. Based on this constraint, a fast stereo cross-correlation algorithm and correlative 3D reconstruction process were introduced. Epipolar rectification, 3D sparse and dense reconstruction results show the validity of the algorithm
