针对缺少地面控制点（GCP）的遥感影，探讨一种几何精纠正的新方法，就是把空间投影理论应用于遥感图像的几何精纠正中，利用空间斜墨卡托投影（SOMP）和少量地面控制点对遥感影像实施几何精纠正，该方法理论严密，算法速度快捷，适用性强，通过对广州地区的TM影像进行的几何精纠正实验，该方法十分有效，几何精纠正精度在一个像素左右。

Aiming at remote sensing images of less ground reference point, we discuss a new geometric exact correction method in this paper. The method applies the theory of space map projection to geometric exact correction of remote sensing images, using spatial oblique mercator projection theory and a few ground reference points to do the geometry exact correction of images. The method is of strictness theory and rapidness arithmetic throughout the experiment of TM image of Guangzhou region, the precision of exact correction is less than one pixel
