| 摘 要： | 提出一种改进的环投影向量模板匹配算法,用于检测高分辨率遥感影像中的道路。该方法对计算环投影值起关键作用的参数Ck进行了改进,优化了环投影值及向量。为了提取更准确的道路中心线,其将环中心点特征加入向量中并给向量赋予不同的权值。实验结果证明,该方法具有较好的鲁棒性,并且提高了道路检测的速度。

| Abstract: | In this paper, a method based on a modified rotation-invariant template matching named ring-pro-jection algorithm was proposed to extract roads in high resolution remote sensing images.Firstly, the parameter crucial to the computation of ring-projection value was modified.Secondly, in order to extract road centerline accurately, we added the center features of the ring to the vectors and set different weights to different vectors accordingly.Experiments showed that the proposed approach speeded up the road detection and was robust to noise. |
