The registration of 3D point clouds is the key problem in 3D surface reverse.A registration method of 3D point clouds based feature points is put forward.Based on the initial registration,the curvature of each point was estimated according to the point and its neighbor points.Curvature is determined in accordance with the characteristics of point set and correlation is adjusted in accordance with the direction of the vector,which decrease the searching load of ICP and improve the efficiency of the ICP algorithm.The accuracy of improved algorithm will not be affected to improve the matching speed.The effect of the algorithm is verified in the applications.
