带有地面高程信息的遥感影像计算机分类方法与实现

Classified method and realization of remote sensing image calculation with ground elevation information

以ENVI软件为基础,通过分析带有地面高程信息遥感图像的校准、噪音清除、波段比值分析、消除地物光谱特性变动等处理方法,探讨了带有地面高程信息的遥感影像计算机分类方法。把地面高程信息作为遥感影像分类的一项辅助信息,将使分类后的图像结果更接近真实的地面实际情况,满足分类后的应用要求。

Based on ENVI software, the computer classified method of remote sensing image with ground elevation information is studied by analyzing the processing methods of calibration, noise elimination, band ratio analysis, characteristic change cancellation of feature spectrum etc. of remote sensing image with ground elevation information. Taking the ground elevation information will make image result after classification approach real ground circumstance, satisfy the applied requirement after classification.
