摘要
利用ENVI4.8软件,以白音图嘎地区高空间分辨率WorldView-2数据为数据源,根据波段特点和数据统计特征,优选8、5、1波段进行彩色合成。对合成图像进行反差增强、纹理增强等处理,在此基础上对岩性信息进行了提取。采用方向滤波等方法,对构造信息进行提取并对其进行分析。结果表明,采用多种方法综合运用,可明显提高遥感图像的视觉效果,有利于信息提取,具有良好的应用效果。
Using ENVI4.8 software, taking the wavelength bands features and statistical characters of the high spatial resolution data in Baiyintuga region as examples, a series of questions, such as color weakly contrast ofdifferent lithology,the same object with different spectrums, shallow layer rock covering, were analyzed inthe pr^ess of lithological identification and arrived atthe best wavelength bands8, 5,1. On the basis,throughthe contrast enhancement and texture enhancement, the lithological information wa- sextracted. The construction information was analyzed by means of directional filtering. The results showed that the application of multiple methods can obviously improve the visual effect of remote sensing image, which is helpful for information extraction and had good application effect.
