Abstract

The invention relates to a GPS track and road matching method and device, a storage medium and a terminal, and the method comprises the steps: compressing track point data to form a broken line; obtaining a road set according to the broken line and the road map layer; and performing even graph matching on a plurality of roads in the road set and the broken line to obtain a road which is most matched with the broken line. According to the method, the offset of the trajectory point data can be filtered and compressed, and the road which is most matched with the trajectory point data can be accurately selected.

Description

technical field [0001] The present invention relates to the technical field of GPS track and road matching, and more specifically, the present invention relates to a method, device, storage medium and terminal for matching GPS track and road. Background technique [0002] With the rapid development of location services based on positioning technology, a large amount of vehicle trajectory data is continuously generated. By analyzing these trajectory data and digging out useful information, better information services can be provided. Due to the error of GPS positioning data, there is a deviation between the GPS positioning result and the actual geographical location, which causes difficulties in location-based services. use. [0003] Under current circumstances, the matching operation of the GPS track and the road through the method of GPS measurement is suitable for areas with a wide field of vision and fewer obstacles. In the city, due to the interference of buildings and...
