Intersection lane marking method, device and storage medium

Abstract

The embodiment of the invention provides a method, a device and a storage medium for marking a lane in an intersection. By collecting a large amount of driving data of a vehicle, the driving data areclassified into different types of sub-data, and the driving behavior corresponding to the same type of sub-data is the same. According to the type, according to each type, curve fitting each type ofsub-data to get the virtual lane in the intersection; Mark virtual lanes on high-precision maps. In this process, the virtual lane in the intersection is automatically fitted, and the virtual lane ismarked as the intersection lane, so as to improve the efficiency and accuracy of marking the intersection lane.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of map drawing, and in particular to a method, device and storage medium for marking lane lines in intersections. Background technique [0002] High-precision maps play a vital role in scenarios such as location search, automatic navigation, and even automatic driving. In the process of automatic driving, the self-driving vehicle drives according to the pre-planned path on the high-precision map, and the path must be accurate to at least the lane level. Therefore, when making a high-precision map, it is necessary to display lanes on the high-precision map. [0003] In the process of making high-precision maps, lanes need to be drawn on electronic maps. Wherein, the lanes include lanes in ordinary roads and lanes in intersections, and lanes in intersections include lanes in intersections such as intersections and T-junctions. For the lanes in the intersection, it is required that ...
