遥感影像变化检测方法研究

Study on Remote Sensing Image Change Detection Methods

本文总结了遥感影像的处理方法及变化检测方法的选择,探讨了分类后变化检测方法,通过该方法对两幅时相同一地区的遥感影像进行处理和分析,将获取的遥感影像进行预处理,利用非监督分类的方法分别对遥感影像中的地物类型进行分类,结果表明:通过分类后比较法发现和提取土地利用类型变化信息检测效果更好。

The paper tion detection method method, the obtained results show that using summarizes the selection of remote sensing image change detection method and discusses the classifica- Then two remote sensing images of the same area at different time are processed and analyzed by this images are pre-processed and the cover types are classifed by unsupervised classification method. The the classification and comparison methods can detect the land use change effectively.
