| 摘 要： | 针对SPOT全色影像提出了一种道路网络提取算法.首先对原始影像进行迭代阅值、中值、形态滤波处理,再细化得到道路中心线,然后去除伪道路线,最后对道路线连接得到道路网络.通过试验表明这种方法具有一定的适用性.

| Abstract: | In this paper,we use the approach of threshold segmentation to detect the road pixels,and then utilize a series of methods to remove the noises,extract the road center line,remove the false road lines,and connect the broken road lines.The results indicate that the road networks extracted by this approach are fairy exact. |
