Research on lithologic information enhancement method based on spectral chromatic aberration

在深入分析了常用多光谱和高光谱遥感岩性信息增强方法特征的基础之上,提出了一种基于光谱色度差异增强岩性信息的方法,使其能够充分利用多波段或高光谱遥感数据中丰富的岩性信息,获得岩性色彩差异最大的图像,为遥感地质解译提供良好的基础影像。该方法应用于WorldView-2多光谱遥感数据和CASI/SASI高光谱遥感数据处理中,取得了很好的岩性信息增强效果,表明这种方法在遥感地质解译工作中能够发挥重要作用,也为遥感技术在基础地质领域的应用起到了一定的促进作用。

Based on in-depth analysis of the common multispectral and hyperspectral remote sensing lithology enhancement method,this paper proposes a new lithology information enhancement method based on the spectral chromatic aberration,which can take full advantage of multi-band or hyperspectral remote sensing data,and make the image with the largest color difference of lithology for geological interpretation.In this paper,the method was applied to WorldView-2 data and CASI/SASI data processing,and good lithologic information enhancement effect was achieved,which indicates that this method is of important significance in remote sensing geological interpretation,and promotes the application of remote sensing technology to fundamental geological field.
