摘 要: | 介绍了一种基于光谱曲线特征峰提取的岩石蚀变信息提取方法。对于目前Hyperion数据的空间分辨率所得到的混合光谱,用该方法对精细矿物的识别尚难做到,但可以用于半定量提取矿物蚀变信息。文中提出的方法作为一种航天高光谱数据挖掘手段,目的在于探索基于高光谱数据的蚀变信息提取方法,为高精度、高空间分辨率的航空或未来航天高光谱数据的处理抛砖引玉、探索先行。

Abstract: | This paper introduces a method to extract rock and alteration information based on line absorption extraction. Although it can't identify fine-grained mineral due to the low spatial resolution of Hyperion data, this method can extract mineral alteration information semi-quantitatively. As one of the determining method for space-borne hyperspectral data, the method aims to explore alteration information extraction method and supplies a basis for processing airborne or space-borne high spectral and resolution hyperspectral data in the future. |
