| 摘 要： | 分析了Pope-Hinsken(P-H)算法的基本原理,将其应用于大角度影像的空间后方交会,给出了误差方程和计算方案,并通过对比实验加以验证。结果表明:1)在空间后方交会中采用单位四元数构造旋转矩阵可显著降低算法的初值敏感性;2)与同类方案相比,该方案具有误差方程更简洁、收敛性更强的特点;3)该方案的解算精度与现有方案一致,稳定可靠。

| Abstract: | Firstly,the principle of Pope-Hinsken(P-H) algorithm was analyzed.Secondly,based on P-H algorithm,an adjustment solution to space resection of high oblique aerial image was provided.Lastly,the solution was validated through a set of contrastive experiments.Experimental results showed that: the rotation matrix constructed with unit quaternions obviously reduces the sensitivity of space resection algorithm to its initial values;the error equations of the solution are simpler than other similar algorithms and ... |
