笔者分析研究了新疆准噶尔盆地西北缘地区卫星图象的信息特点,摸索出了几个较成功的数字图象处理方法。其中我们命名为“二次增强处理方法”是比较典型的一个,处理后的图象色调鲜艳,信息量丰富,见到了较好的地质效果。本文的重点研究区是克拉玛依油田以北的扎伊尔山至哈山地区。该区的卫星遥感图象是1976年12月7日美国2号陆地卫星拍摄的。该区的这个季节没有植被的影响,地表景观主要是出露的石炭系、花岗岩、第四系覆盖区的戈壁砂、砾。反映在卫星遥感图象的4波段、5波段、6波段、7波段这四个光谱波段之间,存在着较强的相关性。通过算出的四个波段之间协方差矩阵(见式(1))可明显看出,在式(1)中,矩阵中对角线各元素值
The author analyzes and studies the information characteristics of the satellite images in the northwestern margin of Junggar Basin in Xinjiang, and explores several successful digital image processing methods. Which we named as the “second enhanced processing method” is a more typical one, the image after treatment vivid colors, informative, see a better geological results. The key study area of this paper is Zaire Mountain to Ha Shan area north of Karamay Oilfield. The satellite remote sensing image of the area was taken on December 7, 1976, by U.S. terrestrial satellite No. 2. There is no vegetation in this season in this area. The landscape of the area is mainly exposed Carboniferous and granite, Gobi sand and gravel in Quaternary coverage area. Reflected in the satellite remote sensing images 4 bands, 5 bands, 6 bands, 7 bands of these four spectral bands, there is a strong correlation. Through the calculated covariance matrix between the four bands (see equation (1)) can be clearly seen in equation (1), the diagonal matrix elements
