基于灰度形态学,提出一种从高分辨率遥感图像提取道路网络的方法。首先利用灰度形态特征对遥感影像进行分割,进而得到基本的道路网络轮廓。然后在此基础上,利用线段特征匹配方法提取道路网络。提出的方法能适应于从道路和背景区别不很清楚的遥感图像中提取道路。实验结果也表明,本文方法能有效地从遥感影像中提取道路网络。 更多还原

【Abstract】 Based on grey level mathematical morphology, this paper presents a newly developed approach to extract road network from high-resolution remotely sensed image. First, the image is segmented based on grey level morphological characteristics, and basic road network can be obtained. Then final road network is extracted from the basic road network by line match method. The proposed approach in the paper can be adapted for road extraction from the remotely sensed image where road cannot be differenti... 更多还原
