摘要(Abstract)：

针对HIS空间变换阴影检测方法仅利用三原色波段数据进行阴影检测而未考虑影像数据之间的相关性及冗余度这一问题,该文结合最佳指数法提出一种适用于多光谱的Worldview-Ⅱ遥感卫星影像阴影检测方法,并引进归一化水体差异指数剔除掉水体的干扰,构建出适用于阴影检测的波段指数模型。实验结果表明,该方法针对Worldview-Ⅱ影像具有普适性,且相对于利用三原色数据进行阴影检测方法能更有效地避免植被信息的干扰,能够精确、快速地检测阴影区域,对后期的阴影去除等研究具有重要的参考价值。

关键词(KeyWords)： 阴影检测;Worldview-Ⅱ;HIS变换;最佳指数;水体指数
