Abstract

The present invention relates to an electronic map path matching method, system, server and readable storage medium. The present invention generates sequential track points by sampling the source paths of other maps, and calculates and matches according to the distance between the track points and the road. Degree, and the connected road with the highest matching degree with the adjacent trajectory points is used as a local matching road, and then the local matching road is connected to obtain a global matching road, which achieves the technical effect of dynamically matching map paths from different sources to the target map. It is convenient for route planning of automatic driving and vehicle navigation, associating low-precision and high-precision road data, which solves the problem in the prior art that the lane data of the traditional electronic map and the lane data of the high-precision map need to be manually correlated, which is inefficient technical issues.

Description

technical field [0001] The invention relates to the technical field of high-precision maps, in particular to a method, system, server and storage medium for path matching of an electronic map. Background technique [0002] At present, the information system based on electronic maps is playing an increasingly important role in traffic assistance and guidance, especially when devices such as smart phones and tablet computers are more and more popular based on digital maps, the role of electronic maps more powerful. [0003] At present, the driving paths of different map data cannot be directly applied, and a manual method is required to establish an association through ID. However, the manual method is slow in processing and low in processing efficiency, which greatly hinders the real-time performance of map and navigation data services. [0004] Most of the current mobile phone map navigation uses traditional map data, while most of the auto-driving car navigation uses high-...
