| 摘 要： | 因单站成像的信息欠缺以及成像的对称性,光学单站姿态处理的二义性是普遍性难点问题,针对光学单站姿态处理二义性解问题,以目标主体直线矢量与姿态角对应关系为突破点,以主体直线矢量的物像映射关系为单站姿态处理基础,从处理结果界定局部二义性错误解,然后根据单站姿态求解关键步骤修正二义性解,修正前后处理结果与常规交会处理结果比较效果显著,在文中所述场景下,误差量级至少缩小20%,该方法为光学单站姿态处理获取正确解提供了可靠理论支持。

| Abstract: | 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. |
