| 摘 要： | 阐述了城市遥感影像中道路提取的特点,以及当今道路特征提取的一些研究成果。根据城市道路的特点,设计了根据植被指数先提取道路两旁的植被方法,通过面积阈值和形状指数阈值剔除图斑,以及应用数学形态学,对图像进行细化,可以提取道路目标。实验结果证明这一方法的正确性。

| Abstract: | In this paper, the feature of road extraction of urban area and the research on road extraction nowdays are discussed. According to the feature of urban road, a way is proposed about vegetation index (VI) to extraction the vegetation around the road. Through the threshold of area and shape index to delete the plate and the mathematical morphology ,the road can be extracted. Experiment result show that the method is effective. |

| Keywords: | road extraction NDVI mathematical morphology thinning |
