Abstract

The present application relates to a method for generating lane lines and related devices. The method includes: acquiring images containing lane lines collected during vehicle driving within a set time period, and acquiring geographical location information data of the vehicle within the set time period; generating vehicle movement information data according to the geographical location information data of the vehicle track line; according to the image, generate a lane line feature point set; according to the distance between each lane line feature point in the lane line feature point set and the vehicle moving track line, divide the lane line feature point set into at least A feature point set of the same lane line; at least one initial lane line is generated according to at least one feature point set of the same lane line. The solution provided by this application can generate the lane lines required by the high-precision map.

Description

technical field [0001] The present application relates to the technical field of navigation, in particular to a method for generating lane lines and related devices. Background technique [0002] High-precision maps are an indispensable infrastructure in the era of autonomous driving. Lane lines, as the basic elements of high-precision maps, are crucial in the process of generating high-precision maps. [0003] In related technologies, a high-precision map is generally generated from laser point cloud data of the road. It mainly recognizes the lane line point cloud from the laser point cloud based on the reflectivity difference of different materials, and then recognizes the lane line based on the lane line point cloud. Or generate lane lines by manually marking in the laser point cloud data of the road. [0004] However, the cost of generating lane lines by using laser point cloud is too high, and the anti-interference ability is poor, which is prone to false detection. ...
