中文摘要：

经典的共线方程中物方坐标系建立在地球表面，在航天摄影测量中，地面摄影测量坐标系的应用，增加了不同类型测量数据间联合处理的难度，限制了影像数据摄影测量处理的空间范围。本文介绍了基于视线方向的影像对地定位算法原理，并以此为基础建立了地心系下的航天影像摄影测量共线方程。针对地固地心系和空固地心系下星历数据的不同点，建立了基于两种地心系下星历数据的航天遥感影像定位严密模型，并对两种模型中偏流角处理的不同点进行了分析，最后给出了一个应用试验。

英文摘要：

For classical collinearity equation, the photogrammetric coordinate system is based on earth surface. For space photogrammetry technology, the difficulty increases while processing different types survey data synchronously because of applying geodetic local coordinate system, which also limits the spatial scope of image data processed with triangulation technology. The algorithm of ori- entation from image to surface based on the CCD light of sight was introduced in this paper. Then space photogrammetry collinearity equation and 3D image positioning model based on geocentric coordinate system were build. The processing difference for deviant angle in image location models with different forms of ephemeris in ECI or ECR system was described. An example was given in the end.
