摘要: 为了进一步探讨Worldview-2数据在岩性识别工作中的应用效果,笔者选择新疆喀什地区阿尔塔什沉积岩区进行遥感岩性增强方法研究.通过对研究区内实测岩石波谱曲线和Worldview-2数据进行分析,对比不同岩性之间的光谱差异,在综合考虑异物同(近)谱、表层浅覆盖等的基础上,结合WorldView-2数据的波段特点和数据统计特征,确立了波段组合-波谱增强-去相关增强-纹理信息融合的处理方法.有效提高了不同岩性之间的对比度,改善了外界因素对光谱信息的干扰,为精确识别不同岩性提供了可靠基础.Abstract: In order to further explore and discuss the application effects of Worldview-2 data in lithology identification, we chose Kashi Altas District in Xinjiang as our research area for Remote Sensing lithology enhancement study in this paper. Analyzing the measured spectrum curves of rocks and Worldview-2 data in the study area, we contrasted the spectral differences among different lithology. After comprehensively considering objects with the same spectrum and the shallow cover, integrating the band feature and data statistics properties of Worldview-2 data, we established a processing method, namely band combination-spectrum enhancement-decorrelation reinforce-texture information fusion. This method has effectively risen the contrast ratio among different lithology and greatly improved the external interference factors on the spectral information. In addition, it has also provided a reliable basis for accurately identifying the different lithology.
