摘要：

云一直是遥感图像预处理和分析中的一大难点,本文在分析南极地区成像特点的基础上,试图利用增强型主题成像传感器(ETM+)获取影像的多波段特点,对南极格罗夫山地区ETM+卫星影像进行云的检测。结果表明,该方法不仅能比较成功地检测极地云层像元,而且能有效地去除部分厚云的影响。

关键词: 增强型主题成像传感器(ETM+);云检测;多光谱

Abstract:

Cloud is a large obstacle to remote sensing image preprocessing and analysis at all times. This paper mainly aims at extracting cloud from Enhanced Thematic Mapper Plus(ETM+) images of Grove of Antarctica basis of analysing multi-spectral characteristics of images of Antarctica. The result indicates this method can not only detect the cloud of polar region successfully, but also remove influence from thick clouds partially.
