摘要
随着地学信息的多源化,同一地区的多种遥感影像数据(多时相、多光谱、多传感器、多平台和多分辨率)越来越多,同时航空物探测量和航天遥感技术在地质工作中起着越来越重要的作用。研究利用遥感图像和航放数据作为数据源,对遥感图像作主分析,在几乎不丢失遥感数据信息的基础上,再利用HIS变换与航放数据进行融合,使U(铀)的微弱信息得以增强,从而指导地质工作者在北方寻找砂岩型铀矿。
With the development of multi-source geo-science information, there are increasingly more data of various remote sensing images multi-time phase, (multi-spectrium, multi-senser, multi-plateform and multi-resolution) for a region. Meanwhile, the airborne survey and remote sensing technology is playing an ever more important role in geological work. In this study, principal component analysis was made on remote sensing images with remote sensing images and airborne gamma spectral data as the data source. Based on little loss of remote sensing data information, the merge of HIS conversion and airborne gamma spectral data was made to strengthen the faint U (uranium) information so as to guide geologists to search for uranium resource in the north region.
