在变化检测中Landsat-7异常数据处理方法试验

摘要

为了更好地利用Landsat系列卫星影像进行变化检测,本文对以SLC-off方式获取的Landsat-7影像进行修复处理,使其能够参与变化检测.本文试验对比3种常用异常数据修复模型,认为多影像局部自适应回归分析模型修复方法最适合后续进行的变化检测,并总结了Landsat-7异常数据参与变化检测的流程方法.%In order to make better use of Landsat series of satellite images for change detection,Landsat-7 image paper will SLC-off way to get the repair process,to enable them to participate in change detection.In this paper,experimental data comparing three abnormal repair model that local adaptive regression model of multi-image restoration method best suited to carry out the subsequent change detection,and summarizes the data flow of the method Landsat-7 anomalies in climate change detection.
