变化检测技术及其在高分辨率卫星遥感影像中的应用

对高分辨率遥感卫星影像利用变化检测技术更新现有的影像数据库或地图数据库是一项对测绘具有重要意义的工作。对现有的变化检测技术进行了分类总结,然后提出了对高分辨率遥感卫星影像进行变化检测的实施流程,最后结合数学形态学算法对SPOT5影像(2.5 m分辨率)进行了相关实验。

Change Detection and Its Application in High Resolution Satellite RS Images

It is very important that using change detection technology based on high resolution satellite remote sensing images to update existing image and map database.In this paper,existing change detection algorithms are summarized,and a process of change detection based on high resolution satellite remote sensing images are proposed.The process includes four steps,pre-processing,classification,feature detection and change detection.And key algorithms in these steps are introduced in details.Then we carry on experiments on SPOT5 images with mathematics morphologic,and good results has been achieved.
