基于6S模型的遥感图像大气校正方法
Atmospheric Correction of Remote Sensing Image Based on 6S Model
摘要
去除大气影响是遥感影像应用中具有重要实用意义的一步,因此依据多光谱遥感数据开展了大气校正方法的研 究工作。基于6S辐射模型和消除邻边效应的经验方法对ZY-3卫星影像数据进行大气校正；作为对照,对同 一影像也做FLAASH(一种成熟的大气校正软件模块)大气校正处理。由结果所见,校正后影像质量得到提 高;校正精度与FLAASH精度都在10%左右,具有较高准确性。
Abstract
Atmospheric correction is important for land remote sensing application. In data processing over multi-spectral remote sensing land image, an atmospheric correction method is presented. The method is based on 6S radiative transfer code and an empirical method of decreasing adjacency effect. To evaluate this correction procedure, FLAASH (another mature atmospheric correction model) is processed as a comparison. Results suggest that the quality of corrected image is improved apparently, the accuracy of the method and FLAASH remain about 10%.
