摘要
针对由道路实体空间逻辑描述差异引起的导航数据与制图数据匹配准确率低的问题,该文提出了一种层次化表达模型辅助的导航与制图道路网匹配方法。首先,构建导航数据层次化表达模型,使用多实体属性关联方式描述复杂对象。然后,在几何匹配部分使用改进动态时间规整(DTW)距离获得最优匹配集。最后,在层次化表达模型辅助下分主次匹配得到最终结果。实验表明,综合场景下该方法对于单、双线道路的匹配准确率达到90%,自定义阈值的设定具备较好的可操作性和灵活性,能很好地适应一对多匹配场景。
Aiming at the problem of low matching accuracy between navigation data and mapping data caused by differences in spatial logical description of road entities, a navigation and cartography road network matching method assisted by hierarchical representation model was proposed. Firstly, a hierarchical representation model of navigation data was constructed. This model employed a multi-entity attribute correlation approach to characterize complicated objects. Then, an enhanced DTW distance calculation method was designed to obtain the optimal matching set. Finally, the final result was obtained by sequential matching and integrating using the hierarchical representation model. Experimental results indicated that the matching accuracy of this method for single-and dual-carriageway roads in the comprehensive scene reached 90%. In addition, the setting of custom thresholds in this study exhibited good operability and flexibility and could adapt well to one-to-many matching scenarios.
