Title:
交差点モデルの作成方法、装置、機器及び媒体
Document Type and Number:
Japanese Patent JP7116391
Kind Code:
B2
Abstract:
The present disclosure provides a method and an apparatus for building an intersection model, an electronic device and a medium. The method includes: identifying a plurality of intersection nodes each having a multiway intersection node attribute based on road network data of an electronic map; grouping the plurality of intersection nodes based on a neighboring relation between the intersection nodes to obtain a plurality of intersection node groups corresponding to multiway intersections; and building an intersection model based on intra-group intersection nodes in each of the intersection node groups, links associated with at least two intra-group nodes in each of the intersection node groups, and links associated with intra-group intersection nodes in each of the intersection node groups and extended to outside of the multiway intersection corresponding to the intersection node group. The disclosure improves the efficiency and comprehensiveness of building the intersection model of the multiway intersections.
