遥感影像中道路交通标志线的去除

针对遥感影像中路面交通标志线对车辆提取造成干扰的问题,提出了一种基于灰度数学形态学与双边滤波相结合去除路面交通标志线的算法。首先,利用交通标志线与车辆目标的几何结构特征,设计了特殊的形态学结构元素对交通标志线进行粗滤除;然后,设计了一种自适应设置灰度方差的双边滤波方法对图像进行精滤除。实验结果表明,该算法对滤除遥感影像路面交通标志线有较好的效果。

Eliminating Traffic Signs Line in Remote Sensing Image

In view of the problems of traffic signs line interfering vehicles extracting in the remote sensing image, a method based on grey scale mathematical morphology and bilateral filtering for removing traffic signs line is presented. Applies the geometric structure characteristics of traffic signs line and vehicle targets to design specially morphology structural elements for roughly filtering traffic signs line, then designs a bilateral filtering method of adaptive setting the gray variance for fine filtering the picture. The test result shows that the algorithm has better effect in eliminating the traffic signs line in remote sensing images.
