The total least squares method which takes the observation vector and the coefficient matrix weight ratio into count is applied to 3D coordinate transformation.The calculation steps of the prior unit weight variance method and the minimum objective function method for determining the scaling factor of observation vector and coefficient matrix was proposed.The characteristics and practical range of two methods were summarized in the example and some useful conclusions were drawn.
