根据高分辨率遥感影像中道路宽度变化均匀、局部方向稳定等几何特征,提出了一种基于距离约束的高分辨率影像道路的提取方法。该方法根据图像相邻边缘像素间的距离值,依次提取道路边缘像素和道路曲线段,然后编组连接各个道路段,实现道路提取。 【英文摘要】 According to the geometric characteristics of high-resolution remote sensing image such as the uniform of change in the width and the stability of the local orientation of the road,this paper presents an approach to extract roads based on distance constraints.According to the distance between adjacent edge pixels in the image,sequentially the experiments extract edge pixels and road curve segments,marshalling and link those curve segments and get the road extracted finally.The experiments indicate that the ...
