Title:
ROAD ELEMENT LABELING METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/185275
Kind Code:
A1
Abstract:
A road element labeling method and apparatus, and a device and a storage medium, which relate to the technical field of maps, and can be applied to the field of maps, the field of transportation, etc. The method comprises: acquiring a road shape line point sequence of a first road in a three-dimensional map, wherein the road shape line point sequence comprises a plurality of position points for sketching a road shape of the first road (201); segmenting the first road on the basis of the road shape line point sequence, so as to obtain a plurality of road segments of the first road, wherein a road surface of each road segment is drawn as a plane (202); and if a target road element spans a boundary between two adjacent road segments in the first road, determining a connecting point located on the boundary, wherein the connecting point is used for labeling the target road element on the road surfaces of the two adjacent road segments in a segmented manner (203). When a road element spans two road segments which do not belong to the same plane, the road element is labeled in a segmented manner by means of a connecting point, thus solving the problem of the overlapping of road elements in a three-dimensional map.
