| 摘 要： | 提出了一种兼顾几何连通性与名称一致性的实体化构建方法。首先，对城市道路的实体化原则进行描述；其次，提出基于反比例函数的归一化的几何连通度度量方法，以及基于语义切分的名称匹配度度量方法；最后，通过路口提取、综合匹配度计算、路段匹配、路段连接及借道处理等步骤，实现完整的城市道路实体化构建流程。以郑州市主城区为试验区域进行具体构建试验，验证了本方法的准确性。试验结果表明，利用本文提出的算法进行实体化匹配的总体准确率为99.89%。

| Abstract: | This paper presents an entity construction method that considers both geometric connectivity and name consistency. Firstly, the entity construction principle of urban roads is described. Secondly, the normalized geometric connectivity degree measurement method based on inverse proportion function and the name matching degree measurement method based on semantic segmentation are proposed. Finally, through intersection extraction, comprehensive matching degree calculation, segment matching, segment connection and lane borrowing processing, a complete process of urban road entity construction is realized. The accuracy of this method is verified by a concrete construction experiment taking the main urban area of Zhengzhou as the experimental area. The experimental results show that the overall accuracy of the entity matching algorithm for road segment is 99.89%. |
