摘　　要：从光谱提取和特征提取两个重要方面总结了目前城市道路信息提取的基本方法,讨论了这些方法的优缺点。根据昆明市QuickBird遥感影像的特点以及城市道路的特点,提出基于Sobel边缘检测算法提取城市道路的流程以及处理方法,对城市道路信息提取的方法进行研究和探索。Urban road network plays a very important role in urban planning and construction. How to grasp the development of urban roads network objectively and real-timely has the very important significance in city＇ s infrastructure construction. This article summarizes the current extraction method of roads information from two important aspects of spectral extraction and feature extrac- tion, and discusses the advantages and disadvantages of these methods. According to the QuickBird remote sensing image of Kunming City and the roads characteristics of the city, the flow and the processing method of road information extracting are put forward with the Sobel edge detection algorithm.
