基于ERDAS的遥感影像变化检测技术的研究

变化检测是遥感图像处理中经常使用的一门技术,随着遥感技术的发展,变化检测的应用越来越广泛。本文介绍了变化检测的定义、流程和应用,利用ERDAS软件进行遥感影像的变化检测实验,并对ERDAS变化检测的几种不同的方法进行比较分析,得出的结论是利用变化检测模块(Change Detection)进行检测的效果较好,最后将这种方法同监督分类技术一起应用于厦门市城市建设用地的变化检测中。

The Research of Remote Sensing Image Change Detection Based on ERDAS

Change detection is a technology which is often used in the remote sensing image processing.With the development of the remote sensing technology,change detection is used more and more widely.The article introduces the definition,the process and the application of the change detection,uses the ERDAS software to do the experiments of the remote sensing image change detection,and compares the different methods of change detection based on ERDAS.According to the compare,the best method of change detection is the Change Detection Model At last,use the best change detection method and supervised classification in the change detection of Xiamen City urban construction land.
