热红外遥感岩矿信息提取研究进展

热红外遥感是岩矿遥感信息领域起步未久，且表现出巨大潜力的技术手段。从岩矿发射率光谱、数据处理及信息提取技术方法、应用研究3个方面对热红外遥感在岩矿信息提取中的研究现状进行了全面总结，在此基础上对其发展难点及趋势进行了讨论，并对其在地质领域的应用前景进行了评估。在数据获取方面，高光谱分辨率数据是应用要求与发展趋势；数据处理方面，对大气影响进行定量评价并力求高精度的大气校正方法是难点与不可回避的问题，大气是影响数据质量的最大因素。岩矿热红外遥感信息机理（矿物发射率光谱特征与机理、光谱混合行为、光谱变异因素）的定性研究取得了一定进展，定量化的研究是发展趋势；在地质领域，因为可以对矿物种类(包括不含水矿物)及含量进行高精度提取的突出优势，不仅在矿产勘探，而且在基础地质研究方面将发挥巨大作用。

PROGRESSES IN MINERALS INFORMATION EXTRACTION USING THERMAL REMOTE SENSING

Thermal remote sensing is a promising technique that develops for not a long time in remote sensing of minerals.The technique development is summarized comprehensively in terms of minerals emissivity spectra characteristic,data processing,information retrieval and application.On the basis of this summarization,the development difficulties are discussed and applications for geology are predicted.Obtaining hyperspectral data is development direction;Atmosphere is a dominating factor that affects data quality,and high precision atmosphere correction must be resolved.Quality research of emissivity spectra mechanism has gained some advances,and quantitative research is development direction.Because minerals class(include minerals containing no water) and contents are retrieved by the technique,it can be applied not only on mine exploration but also on basic geological research.
