本文以粤北曲仁盆地为试验场,采用色调(灰阶)特征信息-卫片假彩色密度分割值为基础数据,用数学地质方法对铅锌矿产区域找矿信息预报进行初步探索所用卫片为E R T S-2卫星于1975年12月24日扫描成象,编号是132-44,即广东省《韶关幅》数据系本所遥感地质组通过PHOSDA C-1200型数字彩色图象分析仪在1 50万的MS S 5和MS S 7卫片上,按等单元网格测取各灰阶假彩色密度值(密度值lg 投射光通量透射光通量在选定的区域内,以4×4公里~2的方格(共100 In this paper, based on the test data of Quernese basin in northern Guangdong, based on the shading (gray scale) feature information and the pseudo-color density segmentation value of the patch, the mathematical geology method is used to explore the ore prospecting information in the lead-zinc mineral area. The image of ERT S-2 satellite was scanned on December 24, 1975 with the serial number of 132-44, that is, the geologic group of Shaoguan amplitude data station of Guangdong Province passed PHOSDA C-1200 digital color image analyzer 1 500 000 MS S 5 and MS S 7 Wei films, according to the unit cell grid to measure the false color density of each gray scale (density value lg projected luminous flux transmitted light flux in the selected area to 4 × 4 km ~ 2 Of squares (total 100
