针对夹皮沟找矿,在两个方面研究:①采取掩膜处理、阈值切割、比值、光谱角等多种方法综合分析并去除目标影像的植被、阴影、河流水体及其冲积物等众多干扰信息;②采用单窗算法对ETM遥感影像中的热红外波段进行地表温度反演,根据地表温度的反演影像进行遥感解译构造,对蚀变异常区域和构造解译影像做叠合分析,找出成矿远景区和成矿有利区,圈定可能的成矿靶区,得到了很好的结果。 更多还原

【Abstract】 For research purposes and the study area,the focus of this paper lies in two aspects:first,take the mask processing,threshold-cutting,ratio of spectral bands,spectral angle mapper and other comprehensive analysis methods to remove the noise information such as vegetation,shadows,rivers and water body disturbance of sediment,and so on.Second,take the single-window algorithm to invert the surface temperature using the ETM+ remote sensing image’s thermal infrared spectral band.Conduct the geologica... 更多还原
