摘要: 同名道路或者居民地数据间由于数据一致性程度不高,往往存在较大的几何位置偏差,当对道路或者居民地单独进行匹配时,不利于提高匹配正确率和效率。针对这一问题,本文提出了一种利用城市骨架线网的道路和居民地联动匹配方法。联动匹配即模仿人在读图时通过特征地物和空间关联寻找目标地物的思维过程,将匹配看作是一种特征目标寻找、信息关联传递的推理过程。首先,利用约束Delaunay三角网对地图构建城市骨架线网。然后,通过道路、骨架线、骨架线网眼和居民地之间的拓扑关系建立道路和居民地之间的匹配传递模型。最后,根据该传递模型实现通过道路匹配带动居民地匹配或者通过居民地匹配带动道路匹配的联动匹配。该方法优势在于只要有一种要素的数据一致性比较好,就能带动另一种要素取得很好的匹配效果,同时符合人类进行匹配时的认知过程。

Abstract: Obvious data consistency degree is not high in roads or habitation data, often in the presence of large geometric position deviation, which is not conducive to improve the accuracy and efficiency of road or habitation matching. A linkage matching method for road and habitation by using urban skeleton line network is proposed to solve this problem. The linkage matching imitates the human thinking process of searching for target objects by the signal features and spatial correlation when reading maps, regarding matching as a reasoning process of goal feature searching and information association transmitting. Firstly, urban skeleton line network is constructed by constraint Delaunay triangulation network; then, the topological relationship among road, skeleton line, skeleton line mesh, habitation is constructed; last, matching transmission model is established by the topological relationship. According to this matching transmission model, linkage matching is fulfilled, which contains road matching drives habitation matching or habitation matching drives road matching. The advantage of this method is that as long as there is an element of data consistency is good, can drive another element to obtain a very good matching effect, at the same time conform to the human cognitive process.

Key words: urban skeleton line network, road matching, habitation matching, linkage matching, topology relationship
