The application discloses a method, device, device and medium for establishing an intersection model, and relates to the technical field of data processing. The specific implementation scheme is as follows: identifying multiple intersection intersections in the road network data of the electronic map that conform to the attributes of the composite intersection intersection point; The intersection point group corresponding to the intersection; the intersection model is constructed according to the intra-group intersection points in the intersection intersection group, the routes associated with at least two intra-group intersection points, and the routes associated with each intra-group intersection point and the group out-of-group points. The embodiment of the present application improves the construction efficiency and comprehensiveness of the intersection model of the compound intersection.
Description
technical field [0001] The present application relates to the technical field of data processing, in particular to electronic map technology. Background technique [0002] When using map software for navigation, the traffic lights and turning conditions of each intersection are usually broadcast. In order to ensure the accuracy of the broadcast results, it depends on whether an intersection model corresponding to the broadcast intersection is stored in the electronic map. [0003] Due to the wide variety of compound intersections, the efficiency of building intersection models for different types of intersections is low, and certain types of intersections may be missed. At the same time, when classifying intersections, classification errors will occur due to the similar intersection types, resulting in an incorrect intersection model finally established. [0004] In view of this, how to achieve efficient and comprehensive establishment of intersection models for different ...
