Abstract:

This paper describes an efficient algorithm for laser point cloud auto registration based on the unit four elements method.We find out the closest matching point by calculating the eigenvectors of the laser point cloud via repeated iterations,and obtain the optimum solution to the rotation and translation matrices of this point,thus achieving the precise automatic alignment of the point cloud.
