Determining exterior orientation parameters (EOPs) of image is an important task in photogrammetry, and various classical methods are in use. On consideration of some shortcomings in classical methods, a new algorithm based on quaternion is presented. The method uses unit quaternion to represent rotation. Based on the least square principle, the closed-form(More)
The optimal produce coefficient of the background value is put forward and the computation formula has been derived by the authors based on the shortages of the computation method of the background value in the GM(1,1) model-grey prediction model, the weighted grey prediction model-PGM(1,1) model has been constructed, the computation of the optimal produce(More)
