| Abstract: | According to the different laser reflection intensity of each cloud point and correcting parts of the coefficient matrix A column vectors, the weighted total least square (WTLS) methods in the plane target and sphere target fitting of the terrestrial laser scanning is introduced, a more reasonable model than the least square (LS)methods and the total least square (TLS) methods is established,and the corresponding iterative algorithm is given.The calculated example proves that the model is more reasonable indeed and the more accurate parameters solution can be obtained with WTLS. |
