As the most critical step,stereo matching has play a decisive role on the stereo vision.According to the epiplastra constraint and same point of the same phase,a new phase based stereo matching algorithm is proposed in this paper,in order to match feature points more efficiently.It is the polar line of the corresponding point is made by epiplastra constraint,and image package phase is get by the four step phase shift method,and phase is extracted by phase unwrapping method of synthesized frequency,then corresponding points of same phase are found this epiplastra constraint.Experiments show that the running time of this algorithm is much faster than the minimum distance method from polar,and verified the effectiveness of the algorithm.
