Abstract: During the course of 3D reconstruction from a set of images,to some limitations in traditional algorithms a new efficient algorithm of points correspondence matching based on a new affinity measure is developed.Through this method,image points matching and 3D reconstruction can be operated in parallel.In this paper,the algorithm of points matching and reconstruction across images is presented.Experimental results on synthetic and real data demonstrate the effectiveness of the method.
