Abstract:Aiming at the problem of false matching generated easily in traditional multi-view epipolar geometry constraint methods combined with angle and distance constraints, the criterions describing the correct corresponding results and a constraint of distance/angle maximums absolute difference are presented. Together with epipolar geometry constraint, it can quickly produce a small and exact searching region, and then the right results can be obtained after similarity constraint. The results and practical examples show that the method can simplify the calculation obviously, promote efficiency and accuracy for homologous points corresponding, and it is useful and effective.
