基于颜色和纹理特征的道路网络自动提取研究

Research on automatic extraction method for road network based on color and textural features

提出了一种从高清晰的航拍图像中自动地提取出道路网络的方法,要求的输入仅仅是彩色航拍图像.应用了一项修改过的TPA技术;另外,新的开始点提取方法和基于此的新的评估方法也得以应用.该方案主要由三大模块组成:1,第一次道路检测;2,统计与融合;3第二次道路检测,评估及后期处理.

In this paper, an automatic extraction method for road network from high-definition aerial image is presented. The recommended input in this method is merely the color image. The modified technology, TPA, and a new way for the start point extraction are applied in this method. The whole plan is consisted of three modules. 1） the first detection for road network;2） statistics and fusion; 3） the second detection for road network, evaluating and treating the extracting results at last stage.
