Study on an Improved Model for Ill-Conditioned Three-Dimensional Coordinate Transformation with Big Rotation Angles
Abstract To solve the problem of ill-conditioned normal equation coefficient matrix for big rotation angle’s three-dimensional coordinate transformation model, an improved model is put forward, based on coordinate centralization combined with adaptive scaling. Through analysis of an example, it is verified that the ill-conditioned normal equation coefficient matrix can effectively be improved with the model, with results that are more reliable than the existing model.
Key words :
coordinate transformation
big rotation angles
