基于Snakes模型的高分辨率遥感影像城区道路提取方法研究
Urban Road Detection of High Resolution Remote Sensing Images Based on Snakes Model
摘要
基于主动轮廓模型(Snakes)理论研究了高分辨率遥感影像道路的提取。针对高分辨率遥感影像中 道路特征,通过改进现存方法得出更为适合道路提取的主动轮廓模型,并利用其完成道路提取工 作。通过对1 m分辨率的IKONOS影像进行实验,结果表明该方法能够较好地提取出城市高分辨 率影像中弯曲道路的完整对称边缘信息。
Abstract
Based on the active contour model (Snakes) theory, the road extraction of high resolution remote sensing images is studied. According to characteristics of roads in high resolution remote sensing images, an active contour model more suited to the road extraction is drawed by improving the existing method, and the road extraction is completed. IKONOS image of 1 m resolution is studied, and results show that this method can be used to extract the road edge information of high resolution images.
