摘　　要：在对异轨遥感立体像对外方位元素求解的基本模型进行系统阐述的基础上 ,讨论了基于共面条件的后方交会模型改化方法及其和基于共线方程的后方交会模型的融合。给出了外方位元素初值求解的实用算法 ,并利用实测立体像对数据进行了联合平差计算 。This paper mainly focuses on the approach of obtaining camera orientation parameters of remote sensing image pairs from different orbits. The fundamental mathematical models of obtaining camera orientation parameters from collinearity equations and coplanar conditions are discussed in detail. To combine the two models, spatial resection model based on coplanar conditions is modified. Results of the combined model can be obtained with adjustment by observation equations. Algorithms of how to calculate the initial values of orientation parameters are also addressed. The proposed approach is tested with a stereo image pair and some results are given.
