3D Reconstruction Based on a Fast Area-based Stereo Matching Algorithm

Abstract

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 U ₁ > U ₂ . 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
