| 摘 要： | 首先分析了地形起伏引起的像点位移原理,在此基础上,针对一般多项式只适用于平坦地区卫星影像正射纠正的不足,根据地形起伏引起的像点位移的数学推导公式,在多项式纠正方法中引入投影差改正,实验表明,该模型较一般多项式模型在x方向上精度有所提高,适用于高山地影像的正射纠正。

| Abstract: | Through analyzing the principle of image displacement , the paper constructs image polynomial model added with topograph-ic correction, based on according to the point that image displacement due to hypsography can be expressed in a mathematic formula and the shortcoming that the polynomial model is only fitting to plat areas .Experiments show that the accuracy of this model is higher than that of normal polynomial model in X direction in mountain areas . |

| Keywords: | remote sensing image correction the polynomial model projection displacement |
