摘要
系统总结了国内外有关从ＴＭ 图像上提取金矿化蚀变信息的方法技术，并在此基础上加以拓展和深化，形成了“多元数据分析＋ 比值＋ 主成份变换＋ 掩膜＋ 分类（ 分割）”这种具有快速、准确、有效特点的识别提取“矿化弱信息”的方法。应用该方法技术先后在新疆、内蒙古及江西、云南提取金矿化蚀变信息。
The techniques about extraction of mineralization and alteration information from remote sensing images domestically and abroad are systematically introduced. On the basis of developing and deepening these methods, a new effective method, namely multivariate data analysis+ratio+PCA+Masking+slicing, is constructed. This new method has been successfully used in Xinjiang, Inner Mongolia, Jiangxi and Yunnan.
