摘要：
After the devastating earthquake, change detection with pre-earthquake images and post-earthquake images can find the seriously damaged area quickly, which provides important information for rescue. Shen et al. (2011) researched the influence of image registration error on change detection with high resolution RS images[1]. Rathje (2005), Zhang et al. (2013) made an intense research on the method of change detection to acquire earthquake damage[2][3]. In this paper, we identify earthquake damage by means of regional optimizing correlation coefficient method with processed pre-earthquake ratio image and post-earthquake ratio image, compared with the result acquired only with single band image. The result shows that the effect of the new method is improved obviously.
