摘    要:在遥感图像的处理中,图像分类起到特征提取的作用。结合老挝波罗芬高原铝土矿普查项目,进行遥感图像分类尝试,从遥感图像分类的基本概念和特征出发,分析评价主要遥感图像分类方法的原理特点及监督分类方法的优势与局限性。监督分类以及野外调查、专家知识和特殊地区的分区分类有机地结合起来,大大提高了可操作性和分类精度,经分类处理所得铝土矿、铁矿及砂岩等分布面积,与野外填图实测的结果几乎一致,说明本区所采用的遥感图像监督分类方法对该区找矿十分有效。

关 键 词:遥感  图像监督分类  分类方法

Abstract:In remote sensing image processing,image classification plays the role of feature's extraction.This article takes a experiment on remote sensing image's classification through the exploration on alumyte in Boluofen plateau,Laos.Starting from the basic concept and the characteristic of remote sensing image's classification,the analysis has appraised the main remote sensing image classification method principle characteristic,and unified the Laos bauxite project to analyze the supervised to classify the method the superiority and the limitation.The supervised classification as well as the open country investigation,the expert knowledge and the special local district classification unifies organically,which greatly enhanced the feasibility and the classified precision.After the classified processing,the area of the obtained bauxite,the iron ore,the sandstone and so on the dispersal area,is nearly consistent with the open country plotting actual result,explained the method of the remote sensing image supervised classifies to be extremely effective to this field prospecting.
Keywords:remote sensing  classification of image supervision  method of classification
