摘要
基于ENVI遥感影像处理软件,选取一景Hyperion数据,介绍了应用ENVI软件对Hyperion数据进行遥感影像预处理的流程和方法。主要包括:未定标和受水汽影响波段去除、坏线修复、条纹去除、去除Smile效应、FLAASH校正、几何校正等,通过预处理获得了地物真实反射率数据,为高光谱遥感技术在地质找矿、环境监测、精细农业等领域的应用提供技术支撑。
On the base of ENVI remote sensing image processing software, this paper selects a king hyperiondata and introduces the processes and methods of hyperion data pre-processing based on ENVI. The pre-processing for Hyperion data includes removing zeroed bands and strongest water vapour bands, repairing broken lines,remov-ingstripe, removing Smile effect, correcting FLAASH and correcting geometric. The real reflectance datais obtained by pre-processing, which provides technical support for hyper-spectral remote sensing technology in geology,environmental monitoring, precision agriculture and other areas.
