光学图像和雷达图像的IHS融合方法是提取构造信息的一种较好的信息增强方法,这种方法既可以保留波谱信息,又可以增加图像的立体效果。本文以鄂尔多斯盆地杭锦旗—东胜地区一带为研究区,选用光学TM图像和雷达JERS图像进行了IHS融合处理,重点研究了光学图像波段的选取以及雷达图像的预处理过程,并在融合过程中注意通过光学TM图像和雷达JERS图像之间的直方图匹配,以降低其融合后图像的变化差异度,从而使此种融合方法更适用于研究区的构造信息提取。
The IHS fusion method of optical image and radar image is a better information enhancement method for extracting the structure information. This method can not only preserve the spectral information but also increase the stereoscopic effect of the image. Taking the Hangjinqi-Dongsheng area of Ordos Basin as the research area, IHS optical and JERS images are selected for IHS fusion. The selection of optical image band and the preprocessing of radar image are mainly studied. In the process of fusion, Note that the histogram matching between the optical TM image and the radar JERS image reduces the variation of the image after fusion, so that the fusion method is more suitable for the extraction of the structural information in the study area.
