摘　　要：航空影像中自动提取道路已经成为了一个研究热点,并提出了大量的提取算法,然而道路网的自动提取仍然是件具有挑战性的任务。文中介绍的Snakes模型(基于主动轮廓模型)对于卫星影像中道路提取具有很好的效果。该方法分为道路初始条件的获取阶段和利用初始条件进行道路网跟踪处理阶段,而文中着重分析后面一阶段,且道路网的跟踪处理是在初始条件的基础上完成的。最后通过实验证明,该方法能正确清晰地提取出主干道,并且对于道路弯曲轮廓的提取也非常有效。Extracting road automatic from aviation images is one of the hot problems in some fields,and it has many extraction algorithms.But how to extract the road network automatic is also a very challenging task.Introduce the Snakes model（Based on the active contour model）to extract road,and have a good effect in satellite images.The method has two stages：the stage of obtaining the initial conditions of the road and the stage of using the initial conditions to track and process the road network.Analyse the second stage mostly. Then it can using the initial condition to finish the road network tracking and processing. According to experiment, this method can extract the major artery clearly and correctly, it can also extract the bend of road effectively.
