Abstract The incidence angle has an impact on point clouds accuracyin 3d terrestrial laser scanning.For improving the accuracy，a method of weighted total least squares (WTLS）incidence angle weighting for point clouds plane fitting is proposed.In the method，the weight value of each point is determined by incidence angle，and the weight matrix is defineson the basis of the structure characteristics of coefficient matrix.The experiments with point clouds data of the plane made of three different materials show that the method is more reasonable and more accurate than least squares (LS）and total least squares (TLS).
