摘　　要：传统的摄影测量后方交会用欧拉角描述影像姿态,计算繁杂;直接用9个方向余弦参数的算法参数太多且有内相关性;以四元数作为姿态参数的算法也存在参数冗余的缺点。本文提出了一种基于Rodrigues参数的空间后方交会方法,用Rodrigues参数作为旋转参数,计算简便且无冗余参数,通过算例证明了该方法的正确性和优越性。Traditional algorithm used Euler angle to describe images attitude,involving a large number of trigonometric function calculations,the calculation is complex.The direction cosine algorithm has nine cosine attitude parameters,which is also difficult to resolving.The quaternion algorithm,which uses unit quaternion to describe images attitude,has one nuisance parameter.According to the existing problems,a solution to space resection based on Rodrigues parameters was proposed in this paper.The numerical experiments are done and results show the correctness and superiority of the method.
