【摘要】：针对遥感异常信息提取的难题引入独立式分析法,以青海都兰县铜及多金属矿为例,采用独立成分分析法对研究区做蚀变遥感异常信息提取,提取结果与主成分分析进行对比研究。据相关地质背景及野外实地查证,结果表明,独立成分分析提取结果优于主成分分析,独立成分分析法在提取遥感异常方面具有良好的应用前景,在地质找矿领域具有一定的推广价值。
[Abstract]:In view of the difficulty of extracting abnormal information from remote sensing, an independent analysis method is introduced. Taking the copper and polymetallic deposits in Dulan County, Qinghai Province as an example, independent component analysis is used to extract the abnormal information of alteration remote sensing in the study area. The results of extraction were compared with that of principal component analysis (PCA). According to the relevant geological background and field investigation, the results show that the extraction result of independent component analysis is better than that of principal component analysis, and the independent component analysis has a good application prospect in the extraction of remote sensing anomalies. It has certain popularizing value in the field of geological prospecting.
