Abstract

The invention relates to a lane line marking method and device, a storage medium and a computer program product, the method is used for marking a lane line in an intersection area in a map, the intersection area is connected with a driving-in lane group and a driving-out lane group, the driving-in lane group comprises driving-in lanes driving into the intersection area in the same direction, and the driving-out lane group comprises driving-out lanes driving into the intersection area in the same direction. The driving-out lane group comprises driving-out lanes driving out of the intersection area in the same direction; the method comprises the following steps: determining an included angle between the direction of a first driving-in lane group in driving-in lane groups and the direction of a driving-out lane group; determining driving direction characteristics from the first driving-in lane group to the driving-out lane group according to the included angle; and according to the driving direction characteristics, marking a lane line connecting a driving-in lane in the first driving-in lane group and a driving-out lane in the driving-out lane group in the intersection area. According to the method and the device, the driving data does not need to be collected in the intersection area, the calculation time complexity is low, and rapid and automatic marking of the lane lines in the intersection area is realized.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, and in particular, to a lane marking method, device, storage medium and computer program product. Background technique [0002] High-precision maps play a vital role in location finding, automatic navigation, and autonomous driving. In the process of mapping high-precision maps, related technologies use automated or manual methods to mark lane lines in the intersection area, which requires the collection of a large amount of data or a large amount of calculation, resulting in low mapping efficiency and high mapping costs. SUMMARY OF THE INVENTION [0003] In view of this, a lane marking method, device, storage medium and computer program product are proposed. [0004] In a first aspect, an embodiment of the present application provides a method for marking lane lines, the method is used for marking lane lines in an intersection area in a map, the intersection area ...
