A method for updating an electronic map includes: generating a second electronic map based on a basic version of the first electronic map combined with traffic intelligence information; comparing the first electronic map with the second electronic map for road network roads to obtain a road network The matching result of the road; when the matching result of the road network is the same, compare the regulation information of the road network, and generate a regulation increment package according to the comparison result when it is different regulation information; according to the regulation increment The corresponding relationship between the package and the road in the road network is to be updated on the electronic map to be updated. Through the way of two differential comparisons, the data update can have good inheritability, and the system can automatically generate the regulation increment package to update the map to be updated, which is beneficial to improve the update efficiency of the electronic map.
Description
technical field [0001] The present application belongs to the field of electronic maps, and in particular relates to an electronic map updating method, device and equipment. Background technique [0002] An electronic map is a map stored and consulted digitally using computer technology. Through the route search of the multi-level road network, the road regulation information of road sections and road intersections is loaded in the electronic map, so that users can learn about traffic violation information or road physical restrictions based on the electronic map, which provides great convenience for users to travel convenience. [0003] Due to changes in road planning information, roads may be widened, newly built or demolished. In order to ensure the accuracy of the electronic map, various traffic restrictions and road network roads also need to be updated. However, the current way of updating road regulation information is generally to manually modify the regulation inf...
