Problems solved by technology

[0003] The lane lines in the prior art are obtained by obtaining the coordinate data of all the patches contained in the dynamic objects in the virtual scene, then filtering out the lane line data, and drawing the lane lines, directly from the coordinate data of all the patches There will be some errors in the lane line data obtained through simple screening, which will lead to certain safety hazards in the process of driving autonomous vehicles on the road, and the efficiency of obtaining lane line data through this method is low, and the economic cost is relatively high. high

Abstract

The invention provides a lane line generation method and device, electronic equipment and a storage medium. The lane line generation method comprises the following steps: generating gridded point cloud data; for each grid, identifying the point cloud data belonging to the lane line from the point cloud data corresponding to each grid, and generating a candidate lane line corresponding to each grid according to the point cloud data belonging to the lane line; determining a plurality of first intersection points based on the candidate lane lines; and generating a target lane line according to the distance between the first intersection points. According to the method and the device, the point cloud data of the lane line of each grid in the gridding point cloud data is identified, the candidate lane lines are generated, the candidate lane lines are combined, and the target lane line is generated, so that on the basis of reducing the repetition rate of the target lane line, the drawing precision of the lane lines is improved, and the economic cost of drawing the lane lines is reduced.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a lane line generation method, device, electronic equipment and storage medium. Background technique [0002] With the progress of society and the development of science and technology, self-driving cars, as a product of the development of artificial intelligence, have attracted the attention of artificial intelligence developers. The automatic driving simulation system equipped on the self-driving car needs to use lane lines to provide road guarantee and safety guarantee for automatic simulation driving. [0003] The lane lines in the prior art are obtained by obtaining the coordinate data of all the patches contained in the dynamic objects in the virtual scene, and then filtering out the lane line data, and drawing the lane lines, directly from the coordinate data of all the patches The lane line data obtained through simple screening will have certai...
