Abstract: In the binocular vision technology,for solving the incorrect matching of edge corner,a corner matching algorithm based on edge correlation distance constraint was proposed.Firstly,use corner detection algorithm based on edge to extract corner,confirm candidate corner matching assemble by epipolar constraint and corner’s threshold constraint.Then,put forward the “edge correlation” constraint,structure candidate corner pair’s contribution value based on corner distance to have it fine matched.Finally,structure corner’s vector,and test corner matching further using sub-vector matching method.The experiment results show that this matching algorithm has high accurate rate,solves the incorrect matching problem of edge corner pair effectively,and it’s quite suitable for the applications of edge-based binocular vision.
