随着高光谱矿物识别方法的不断发展,使得高光谱遥感技术在地学领域的应用由定性分析到定量识别成为可能,也为今后开展成像光谱遥感数据的广泛应用做好了技术准备。依据对谱形特征研究角度的不同,把矿物识别方法分为基于特征谱带和基于完全波形特征,并针对这些方法的特点、存在问题及适用场合进行分析,提出进一步需要开展的工作:深入分析和研究岩矿物化属性与光谱特征的相关性;进一步完善遥感岩矿混合光谱数值模拟与分析技术;加强高植被覆盖区岩石矿化蚀变信息提取方法研究。
With the development of the mineral discrimination method of hyperspectral remote sensing,it is possible to use it from qualitative analysis to quantitative discrimination in earth science field. It' s technological preparation for the widely application of remote sensing data. This paper divides the mineral discrimination into two sorts, namely, based on spectral diagnostic zones and based on whole wave shape character. Then the authors discuss the characteristics, problems and applicable occasions of the main discrimination methods of mineral using hyperspectral remote sensing. Finally, they present the following work: analyze and study the relations between mineral property and spectral characteristic; consummate the decomposition of mix spectrum; enhance the discrimination method of mineral covered by dense vegetation.
