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.
Keywords:coordinate transformation  big rotation angles  ill-conditioned  centralization  adaptive scaling
