Abstract
A map matching method, an apparatus and an electronic device related to the technical field of artificial intelligence such as high-precision map, autonomous driving, internet of vehicles, and smart cockpit, where a specific implementation is: when matching a high-precision map with a standard-precision map, firstly acquire road network data corresponding to the high-precision map and the standard-precision map to be matched; and construct a first graph network based on the road network data corresponding to the high-precision map, and construct a second graph network based on the road network data corresponding to the standard-precision map, then determine a matching result between the high-precision map and the standard-precision map based on the first graph network and the second graph network. By the method using the graph network, the matching of the high-precision map with the standard-precision map can be accurately realized, thereby effectively improving accuracy of the matching result.
