| Abstract: | In the process for researching three dimensional coordination transformation adapted to arbitrary rotation angle, with the case of only three control points , an improved constrained weighted total least squares method(ICWTLS) was proposed to solve the model of control points in the two sets having random errors (EIV model).If the control points are rich (four or more),we put forward the multivariate total least squares method (observation equation has not only one row,MTLS) to solve the parameters, and the problem of the repeated random elements of coefficient matrix’s corrections being not equal,and to improve the accuracy of the parameter values. |
| Keywords: | ICWTLS MTLS 3D coordination transformation adapted to arbitrary rotation angle coefficient matrix repeated random elements |
