AI Technical Summary

Technical Problem

When processing road network data from different data sources, existing road network matching methods are prone to matching errors due to the similarity of intersection access and road morphology, which affects the application accuracy of map data.

Method used

By obtaining intersection attribute information and road attribute information from the road network data of each data source, the initial matching information is determined, and secondary matching is performed for parallel road scenes. The topological relationship and layout of intersections and roads are used to group and secondary match the target sections to improve the matching accuracy.

Benefits of technology

It achieves high-precision matching of parallel road scenes, improves the matching accuracy and comprehensiveness of road network data, and ensures the quality of map data.

Abstract

The embodiment of the invention provides a road network data matching method and device based on multiple data sources, equipment and a medium. The method comprises the following steps: acquiring road network data of each data source in the same preset area; the road network data comprises intersection attribute information and road attribute information, the intersection attribute information represents a topological relation between intersection points and roads, and the road attribute information represents a layout condition of the roads; determining a target road section and initial matching information of the target road section in the preset area according to intersection attribute information and road attribute information in each road network data; the target road section comprises a plurality of parallel roads, and the initial matching information represents an initial matching relationship of each road in the target road section in different road network data; and if it is determined that the initial matching information does not meet the preset condition, target matching information is determined according to the road attribute information of the target road section in each path of network data. And through secondary matching, the matching precision of the road network data is improved.
