| 摘 要： | 遥感影像的大气校正是遥感数据应用的基础．文章利用ENVI软件的FLAASH大气校正模块，对Hype—rion高光谱遥感影像进行大气校正，选取典型地物对校正效果进行评价．主观定性评价结果显示校正后的影像地物边界更清楚、对比度增强；光谱曲线对比分析显示，校正前后光谱曲线形状完全不同，林地的反射率图像的光谱曲线形状与USGS...

| Abstract: | Owing to system and occasional errors,atmospheric correction is the basis of application of remote sensing images.Based on FLAASH model in ENVI4.5,the paper implemented atmospheric correction to one scene image of Hyperion data and evaluated the quality of corrected image.Firstly,the boarders between both land cover types were made more clearly from each other in processed images than that in raw images.The local contrast was enhanced from raw images to corrected images.Secondly,double spectral curves of im... |
