Registration sphere for multiple views merging
Wang Li, Guangyun Li, Lei He · Cehui kexue · 2010
Multiple views merging is a key step in point clouds processing,and the Registration-Sphere-Method is widely used in real work,so this paper put great effort on the study of this method.The merging accuracy relies on the accuracy of the sphere center.Aiming at raising the accuracy,the author used RANSAC algorithm to work out the sphere center.RANSAC is a robust algorithm,so the center could be calculated accurately from the points which have errors in them.Experiments and comparisons showed the high accuracy of this algorithm.
