| 摘 要： | 云检测是遥感数据预处理中的一个重要环节。本文通过分析云及典型地物光谱特性,结合HJ-1B传感器波段设置,提出了一种基于多光谱分析的云检测算法。该方法针对不同下垫面类型,选取合适的波段组合逐一建立云掩模。利用该算法对多幅影像进行去云处理,结果表明,该方法能够很好地检测出不同时期不同背景上空的云像元。

| Abstract: | Cloud detection is absolutely necessary in the processing of satellite remote sensing data.Through analyzing spectral characteristics of cloud and typical objectives and integrating the channel characteristics of HJ-1B,a cloud detection algorithm for HJ-1B was proposed based on multispectral analysis in the paper.Taking it into account the different types of underlying surface,it gradually built a cloud detection mask by choosing suitable band combination.This method was applied to remove cloud pixels from many different images.The results showed that this approach could detect cloud pixels over different periods and different scenes successfully,which would promote the use of HJ-1B data and improve the precision of image classification. |
