摘要
介绍了后方交会解算方法中的若干问题,并从理论角度分析和阐述了欧拉角方法出现奇点的原因,建立了欧拉角方法、方向余弦矩阵和四元数方法三者之间的关系。指出了在应用中尽可能使用四元数方法进行后方交会解算,而尽量避免使用欧拉角方法。
Some issues on the selection of resection solving method has been introduced in present article,and the reasons for the singularity of the Euler angle method are analyzed and elaborated from a theoretical point of view.Besides,The relationship among Euler angle method,direction cosine matrix and quaternion method are established.It is pointed out that in the application,the quaternion method should be used to solve the resection as much as possible,but the Euler angle method should be avoided as much as possible.
