Abstract:Aimming at the characteristic of three-dimensional laser scanning data,based on the theory of least squares adjustment ,this paper presents a method for point cloud registration,based on point plane geometric feature. Firstly,according to superposition between two planes,model of point cloud registration and error equation are derived, based on geometric feature of point and plane. Secondly,combined error equation of point cloud registration based on feature points,error equation of point cloud registration is derived,based on geometric feature of point and plane. Finally,making a test,using the actual scan data form three-dimensional laser scanner,confirm that this method can improve the accuracy of point cloud registration.
