Determination method for ambiguous correct solution of optical single-station pose processing

Due to the lack of information and the symmetrical imaging of single-station imaging, the ambiguity of the optical single-station pose processing is a common and difficult problem. Aiming at the ambiguous solution of optical single-station pose processing, the corresponding relationship between the target subject straight-line vector and the pose angle was taken as the breakthrough point, and the object-image mapping relationship of the target subject straight-line vector was taken as the basis of single-station pose processing. Defined the partial ambiguous error solution from the single-station pose processing results, and then the ambiguous solution was modified according to the key steps of single-station pose solution. The effects of processing results before and after ambiguous correction were significant compared with that of the conventional intersection processing results. In the described scenario, the error magnitude is reduced by at least 20%. This method provides a reliable theoretical support for obtaining the correct solution of optical single-station pose processing.
