| 摘 要： | 结合模糊连接度理论和SPOT影像上道路的表现特性提出了主干道路半自动提取的方法。首先,对原始影像进行去噪滤波处理,再人工选取能够代表道路特性的种子点,计算出各个像素点相对种子点的模糊连接度,将模糊连接度值大于一定阈值的像素点提取出来,从而得到道路线的支持区域;接着对二值道路域细化抽去得到道路中心线;实验证明,该方法可以取得较好的效果。

| Abstract: | The new method of road semi-automatic extraction was proposed,which was based on multiseeded-fuzzy connectedness combined with road feature in SPOT image.First,image could be filtered and then seeds were selected from road.And the fuzzy connectedness was calculated between each pixel and seed point of the object.After that,road middle lines were detected through thinning.Experiment indicated the method could gain better results in SPOT image. |
