Research of Point-clouds Registration Based on Least-square Method
基于最小二乘法的点云数据拼接研究

Point-clouds registration is widely applied in reverse-engineering,computer vision and medical imaging,etc.Based on the combined transformation theory of the space coordinates,a registration method,which extracts the transition matrix with multi-points based on least-square method to minimize the transition error,is proposed.Some typical methods are specified and analyzed with practical examples in this paper.Experimental results show that this approach can realize point-clouds registration as the features of rapid speed,high accuracy,stability and simple operation.It is powerful for practical engineering.
