Abstract

The invention provides a road network matching error correction method, device and system. The method comprises the following steps: acquiring an initial road network; extracting traffic relation information from the initial road network, wherein the traffic relation information comprises road segment identifiers of all road segments in a road network, coordinate information of road segment starting points and coordinate information of road segment ending points; on the basis of road network data, determining invalid matching road sections in the initial road network according to the traffic relation information; and carrying out error correction processing on the invalid matching road sections to obtain a corrected target road network. According to the invention, automatic matching errorcorrection can be carried out on the obtained initial road network based on the latest road network data, and error correction accuracy is high.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to a road network matching error correction method, device and system. Background technique [0002] With the rapid development of Internet technology, map navigation technology has become an indispensable tool for people's daily travel. [0003] At present, the pre-production of electronic maps requires a large number of personnel and vehicles to complete the collection and arrangement of roads and driving trajectories. In the existing technology, the corresponding relationship between the high-precision trajectory and a road on the base map or the actual road is generally collected manually, and then manual matching and error correction is performed, so that the road network collected by the vehicle is consistent with the latest road network. match. [0004] However, in this way, the overall process is cumbersome, the workload is heavy, and the error correction efficienc...
