摘　　要：提出了一种基于区域变化率的变化检测方法,该方法在考虑阴影及灰度匹配的基础上,采用区域信息降低由配准误差引起的虚检率。实验表明,本文方法能够在一定程度上消除配准误差的影响。A method is presented to decrease the effects of misalignment. Firstly, the images are registered with a reliable strategy so that the ground can be registered correctly. Then the changes of image are detected with traditional algorithm according to image difference based on iterative radiometric calibration. At last, change rate of segmented image regions are used to improve the change detection results. The experiments show that the false detection of misregistering can reduced greatly.
