%X The coordinate transformation between different coordinate systems includes four parameters: two translations,one rotation,and one scale paramete.When there is ill-condition transformation matrix,the common points' little errors may cause big fluctuation of parameters' results.Considering the unity between coordinate transformation model and centre of gravity datum of free net adjustment,the two translation parameters may be elimineted under auxiliary condition.This method is validated with an example.
