Abstract

The invention relates to a road matching method and a server. The method comprises the following steps of acquiring the position point information captured by mobile equipment to obtain a first position point sequence; selecting position points in the first position point sequence according to a preset rule to obtain a second position point sequence; obtaining a map data tile corresponding to thesecond position point sequence and road data in the map data tile; obtaining a road matched with the second position point sequence in the roads of the map data tiles; and connecting the matched roadsaccording to the position point sequence in the second position point sequence to obtain a road sequence. According to the method, road matching is carried out after the GPS position point sequence is thinned, and operation efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a road matching method and server. Background technique [0002] In the map navigation application scenario, it is necessary to display the track path that the user has traveled, for example, from scenic spot A to scenic spot B, what is the user's driving track. Since the longitude and latitude coordinates collected by the GPS vehicle terminal and the electronic map itself have certain errors, the driving trajectory of the vehicle cannot match the corresponding road in the electronic map, and the moving target deviates from the driving road, causing visual confusion and positioning. The results do not match the actual situation. Therefore, it is necessary to use road matching to match the vehicle orientation point with the corresponding road. [0003] As mentioned above, the problem is mainly due to abnormal positioning equipment or inaccurate positioning accurac...
