城市道路在空间分布上具有一定的规则。我国的城市道路布局主要有方格式、扇形式等。本文针对这种布局规则的道路网，提出一种快速提取道路中心线的方法。通过对图像进行扫描，将属于一条道路的所有像素点归并到一个容器中，提取中心点并输出成道路线。同时，介绍了几种典型道路的处理方法。实验研究表明该方法可以快速、精准地提取道路中心线，具有实际应用价值。

City Road has a regularity in the spatial distribution .The main layout of china’s road is square format, fan format etc.A method is proposed for fast extraction of the centerline of the road according to the rules of the road network layout .Merge pixels be-long to a road into a container by scanning the image and extract the center points and output line .Meanwhile introduce a processing method of several typical roads .The result indicates that the method can rapidly and accurate extract the centerline of the road , and has practical value .
