摘要
根据旋转矩阵的正交特性,在不增加待求参数的前提下,引入斜对称矩阵来描述共线方程,将其线性化后进行迭代来解算像片的外方位元素,实现了单张像片的空间后方交会,算例分析验证了该方法的正确性。该方法不含有欧拉角,一共包含6个待求参数,可为小、中姿态角像片的空间后方交会提供一种选择,一定程度上丰富了摄影测量理论体系。
Based on the orthogonal property of rotation matrix, a kind of skew symmetric matrix is in- troduced to describe collinearity equation. With its linearized model, iterat, ion is used to solve elements of exterior orientation and space resection of single photograph is realized. Finally, the correctness of the method is verified by numeric examples. The approach abandons Euler angles and contains 6 pa- rameters, which could provide an alternative choice for space resection with small or medium attitude angles and enrich the theoretical system of photogrammetry to some degree.
