| Abstract: | The least square configuration model is analyzed in the application of small angle coordinate transformation. The least square, improved bursa, and multivariate total least square models are analyzed in the application of arbitrary angle coordinate transformation, as well as for the impacts of scale factor and rotation angle on coordinate transformation precision by experiment. It is proven that the multivariate total least square model can achieve high-precision coordinate transformation of arbitrary scale factor and rotation angle. |
