【摘要】：針對(duì)遙感異常信息提取的難題引入獨(dú)立式分析法,以青海都蘭縣銅及多金屬礦為例,采用獨(dú)立成分分析法對(duì)研究區(qū)做蝕變遙感異常信息提取,提取結(jié)果與主成分分析進(jìn)行對(duì)比研究。據(jù)相關(guān)地質(zhì)背景及野外實(shí)地查證,結(jié)果表明,獨(dú)立成分分析提取結(jié)果優(yōu)于主成分分析,獨(dú)立成分分析法在提取遙感異常方面具有良好的應(yīng)用前景,在地質(zhì)找礦領(lǐng)域具有一定的推廣價(jià)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.
