利用数字图像处理系统与地理信息系统对航天遥感数据和航空伽玛能谱数据进行复合集成处理,研制出一种光一能谱复合的新类型图像。这种图像既具有多光谱航天遥感图像地理信息丰富、立体感强、便于定位和解决构造问题的长处,又有能谱便于区分岩性、蚀变现象和铀矿化的优点。该图像在试验区实践中,不论是在地质填图的探索、成矿构造的确定,还是在找矿靶区的优选方面均取得了显著的效果,更有效地发挥了航天遥感信息在铀矿勘查中的作用。
A digital image processing system and geographic information system were used to integrate and process the aerospace remote sensing data and the airborne gamma energy spectrum data to develop a new type of photo-spectrum composite image. Such images not only have the advantages of rich geographic information, strong stereoscopic sense, easy to locate and solve the structural problems of multispectral remote sensing images, but also have the advantage of distinguishing lithology, alteration and uranium mineralization by energy spectrum. In the practice of the experimental area, the image has achieved notable effects in the exploration of geological mapping, the determination of metallogenic structure and the optimization of prospecting target areas, and the more effective use of space remote sensing information in uranium mines The role of exploration.
