摘　　要：针对IKONOS影像数据多光谱、高空间分辨率、高辐射分辨率以及生成立体像对的特点 ,提出一种高精度阴影检测方法和实用阴影去除方法 ,真实再现阴影区地物特征 ,增加影像信息量 ,提高数据质量 ,也为其他遥感影像阴影去除提供一种新的研究思路。Based on the characteristics of multispectral, high spatial, and high radiant resolutions of IKONOS data and its ability to form orthographic images, this study presents a new method which detects shadows with high precision and removes them effectively. The results show that the ground features within the shadow region were retrieved accurately. The contents of the IKONOS images were enhanced and quality of remote sensing data was improved. Moreover, this study provides a new research idea for shadow removal from remote sensing images.
