Abstract

The invention discloses an intersection model establishment method and device, equipment and a medium, and relates to the technical field of data processing. According to the specific implementation scheme, the method comprises the following steps: identifying a plurality of intersection points conforming to composite intersection point attributes in road network data of an electronic map; grouping the intersection points and adjacent intersection points of the intersection points according to the adjacency relation between the intersection points to obtain intersection point groups corresponding to the composite intersections; and constructing an intersection model according to the intra-group intersection points in the intersection point group, the routes associated with the at least two intra-group intersection points and the routes associated with the intra-group intersection points and the out-of-group intersection points. According to the embodiment of the invention, the construction efficiency and comprehensiveness of the intersection model of the composite intersection are improved.

Description

technical field [0001] This application relates to the technical field of data processing, in particular to electronic map technology. Background technique [0002] When using map software for navigation, traffic lights and turning conditions at each intersection are usually broadcast. In order to ensure the accuracy of the broadcast results, it depends on whether there is an intersection model corresponding to the broadcasted intersection stored in the electronic map. [0003] Due to the wide variety of compound intersections, the efficiency of establishing 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 may occur due to similar intersection types, resulting in errors in the final intersection model. [0004] In view of this, how to efficiently and comprehensively establish the intersection models of different types of compound interse...
