摘要:为更好地进行遥感影像的信息提取,国内外许多专家都在不断的寻求更有效的遥感影像分类方法。本文将基于envi5.0,采用面向对象的分类方法,利用ikonos高分辨率影像作为数据源,进行甘草信息的提取。首先为更好地进行信息提取,需对ikonos卫星影像进行数据融合,之后基于边缘检测与合并的算法结合影像纹理信息进行影像分割,最后基于样本结合光谱信息、纹理信息等进行影像分类,并得到了较好结果。40248 毕业论文关键字:面向对象分类;ikonos;甘草;envi

Abstract:In order to find the better way to extract the information of remote sensing image, many experts at home and abroad are continuously trying their best to find the more efficient methods in classification of remote sensing image.Being based on envi 5.0, taking the methods of object-oriented classification, using the ikonos high resolution image as the data source to extract the information of Glycyrrhiza uralensis Fisch. Firstly, we need to do the data fusion of ikonos satellite image, then based on the algorithm of edge detection and merging, combined with image texture information for image segmentation, finally, based on the sample, combined with spectral information, texture information and so on for image classification.
