| 摘 要： | 针对经典边缘检测算子在提取道路边缘时，易于受到房屋边界、地类界等线性目标的干扰，使得检测出道路边缘的同时混有其它非道路线现象，提出一种基于边界特性改进直方图门限算法提取道路边缘像素，利用边缘像素改善直方图检测道路像素的方法。该算法首先获取道路边缘像素，然后通过形态学运算得到初始道路段，细化获取道路中心线，最后对其进行判断编组连接得到道路网络。

| Abstract: | When using the classic edge-detection operator to detect road edge,it will be influenced by the verge of buildings and other linear objects.Here we use the approach of threshold segmentation to detect the road pixels,then utilize a series of methods to remove the noises,extract the road center line,connect the broken road lines.The results indicate that the road networks extracted by this approach is fairy exact. |
