中文摘要：

分析了立体卫星影像的核线关系，提出了一种利用高分辨率立体卫星影像有理函数模型确定其精确核线方程的方法，实现了卫星影像有理函数模型对应零高程空间点的定位，并获得了卫星影像的投影轨迹核线的双曲线方程。

英文摘要：

The relationship of epipolar between stereo satellite image is analyzed. An algorithm for rational polynomial camera （RPC） models epipolar determination of high-resolution stereo satellite image is presented, which is used to find exactitude ground point of zero elevation and stereo satellite image hyperbola epipolar of projection track method.
