摘要
在简要介绍认知心理学和感知觉理论的基础上 ,提出了道路模型约束下的基于感知编组的道路网自动提取策略 ,其特点是利用全局特征约束条件对道路段局部编组结果进行迭代重组 ,并使用了启发式图搜索法A 算法来辅助道路段的曲线连接 ,从而弥补了局部编组的缺点 。
Firstly this paper introduces the cognitive psychology and perceptual theory briefly. Then an automatic approach of extracting road based on road model and perceptual organization is presented. This method utilizes the global information to lead the road segments regrouping and uses the Heuristic Graph Search Algorithm-A* algorithm to link the curve parts of road, which improves the result of local grouping and enhances the reliability of road extraction greatly.
