Abstract

从遥感影像中提取道路特征已有许多研究 ,但仍存在许多问题有待解决。本文探讨了道路特征提取的基本思想 ,对道路特征提取的基本方法和现状进行了较全面的综述 ,介绍了具有代表性的特征提取方法 ,并对各个方法的特点进行了分析 ,最后对道路特征提取的研究前景进行了展望。 It is still an open problem to extract road feature from remotely sensed image, although there had been a lot efforts put in this area. This paper describes the general approaches of road feature extraction, reviews the state of the art of the road feature extraction methods, and analyzes the characteristics of these methods. Finally, research issues are recommended for future studies.
