Abstract

The present application discloses a method, device, device and storage medium for marking road elements, and relates to the technical field of maps. The embodiments of the present application may be applied to the map field, the traffic field, and the like. The method includes: acquiring a road shape line point sequence of a first road in a three-dimensional map, the road shape line point sequence including a plurality of position points used to delineate the road shape of the first road; The road is segmented to obtain multiple road segments of the first road; wherein, the road surface of each road segment is drawn as a plane; if the target road element crosses the boundary between two adjacent road segments in the first road, it is determined to be located at the boundary The junction point on the junction point is used to label the target road element segmentally on the road surface of two adjacent road segments. In the present application, when the road element spans two road sections that do not belong to the same plane, the road element is marked in segments by connecting points, so as to solve the problem of overlaying the road element in the three-dimensional map.

Description

technical field [0001] The embodiments of the present application relate to the field of map technology, and in particular, to a method, device, device, and storage medium for labeling road elements. Background technique [0002] In a three-dimensional map (such as a high-precision map), both roads and road elements have height information, and the labeling of road elements has an important impact on the display effect of the three-dimensional map. [0003] In the related art, the roads in the three-dimensional map are spliced ​​together by several triangular patches. In the case where two adjacent triangular patches are not coplanar, if the road element is also drawn flat, the road element and the road will not fit. Even in the case where two adjacent triangular patches form a road with up and down slopes, if the road element is still drawn in a flat manner, the road will cover the road element. Therefore, it is urgent to design a reasonable road element labeling method. ...
