摘　　要：随着空间技术的发展,遥感影像的应用领域扩大,遥感影像的获取数量也不断增多。遥感影像的快速纠正是更好地利用遥感影像的前提,本文提供了一种利用建立控制点库进行几何精纠正的方法。实验证明,利用该方法在提高几何纠正中寻找控制点的效率的同时,可以有效地提高同一地区不同时相的影像配准精度,以及提高相邻影像的接边精度。With the development of spatial technology,the application of remote sensing images is becoming more and more popular and the amount of acquired images is increasing as well.The geometry correction for these images is the precondition to make them better applied.The paper provides an approach to geometric correction by creating the control point set.This method is able to improve the efficiency of looking for the control point and the matching accuracy of images from the same area of different time,which thus improves the precision of edge joining.
