从高分辨率遥感影像中提取道路信息的方法综述及展望

摘要

道路作为城市的重要组成部分,是衡量城市发展的重要标准之一,研究基于高分辨率遥感影像的道路信息提取具有重要的现实意义.一直以来,从高分辨率遥感影像中提取道路特征信息都是研究的热点和难点.本文首先阐述了道路信息提取的思想和基本方法,列举并分析了几种比较有代表性的道路特征提取方法,并指出了其中所存在的问题,最后对高分辨率遥感影像中道路信息的提取研究前景进行了展望.%As important parts of the city,roads are important measures of the city development,so the research of road feature extraction from high resolution remote sensing images has a great practical significance.Extracting the information of road features from high resolution images has already become a research hotspot and difficulty.In this paper,it first introduced the idea and methods of road extraction.Then it enumerated and analyzed several representative methods of feature extraction,and pointed out the existing problems.Finally this paper forecasted the research prospect of road feature extraction.
