基于FLAASH模型的ASTER卫星影像大气校正

Atmospheric Correction on ASTER Satellite Image Based on FLAASH Model

主要介绍了FLAASH大气校正模型的主要原理及算法,并运用FLAASH大气校正模型对泸沽湖地区的ASTER卫星影像进行大气校正,对校正前后的影像进行对比分析。研究表明,ASTER卫星影像经过FLAASH大气校正后,较好地消除了大气影响。

The main principles and arithmetics of FLAASH atmospheric correction model were mainly introduced. FLAASH model was used to make the atmospheric correction on ASTER satellite images in Lugu Lake Area. And the comparative analysis was made on the images before and after correction. The research showed that the atmospheric influences of ASTER satellite images could be eliminated well after FLAASH atmospheric correction.
