摘　　要：本文提出一种基于RFM和投影射线法的异源高分辨率光学卫星遥感影像定位算法:首先利用高分辨率遥感影像RFM正解模型迭代计算其反解模型;接着通过RFM正反解模型构建投影射线,最后采用迭代求取射线交点的方法确定地面三维实际坐标。实验对比结果表明,联合具有一定重叠度的异源高分辨率光学卫星遥感影像进行立体定位具有较强的可行性,并可达到一定的精度。This paper presented a stereoscopic positioning method for multi-source high resolution optical satellite images based on RFM and projection method of radiation. Firstly, an inverse RFM was iteratively built by using positive RFM ; secondly, the projection rays were built by the positive and inverse RFM model. At last, 3D coordinates of ground points were iteratively achieved by ray inter- section. Experimental contradistinctive results verified that the presented algorithm could be feasible to construct stereoscopic pair with multi-source high resolution optical satellite images for stereo mapping.
