摘要
三峡库区三斗坪大坝区及其周围地区在1994到1998年期间,由于大坝的施工地面发生了巨大变化。这些变化在1990、1997和1998年获取的SPOT遥感图像上都有明显的记录,其中一些地面变化细节在分辨率10m的全波段(P)图像更为清楚。这里利用三种方法(高通滤波算法[2](HPFalgorithm,Chavezetal.1991)、RWM-ARSIS方法(RanchinandWald,1999)和P+XS算法[1](Anonymous1986))对三峡工程三斗坪大坝区的多时相高空间分辨率的SPOT图像(获取时间为1990,1997和1998年,包括全波段P图像和多波段XS图像)进行融合处理,在提取测区地面动态变化信息的同时,从理论和实际应用的角度探讨了不同数据融合方法的效果。
