Problems solved by technology

It can be seen that accurate lane lines or other road marking information in high-precision maps can help the generation of key traffic elements in high-precision maps, which is one of the important conditions for automatic driving, and lane lines are fitted using semantic segmentation algorithms. The scheme is prone to misidentification and noise, which reduces the fitting accuracy of lane lines or other road marking information, which in turn affects the accuracy of high-precision maps

Abstract

The invention relates to a data processing method for detecting a lane line, and a storage medium. The method comprises the steps of acquiring sampling pixel coordinates in at least one lane line from an image according to a first preset rule, wherein the first preset rule is used for acquiring pixel coordinates in the y direction of the image; after the multiple sampling pixel coordinates are converted into points in a coordinate system of the unmanned vehicle, obtaining multiple sampling point data; filtering the plurality of sampling point data according to a second preset rule to obtain a target sampling point set, the second preset rule being used for filtering non-target sampling points on a lane line under a coordinate system of the unmanned vehicle; and performing curve fitting processing on the target sampling point set, if the curvature radius corresponding to a curve obtained by fitting processing is greater than a preset threshold value, outputting the lane line, otherwise, giving up output. According to the data processing method for detecting the lane line and the storage medium provided by the invention, high-quality lane line data can be provided for an automatic driving system.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data processing method and storage medium for detecting lane lines. Background technique [0002] With the development of technologies such as artificial intelligence and autonomous driving, vehicle-road integration technology is becoming more and more mature. In the process of autonomous driving, high-precision maps play a role in high-precision positioning, assisting environmental perception, planning and decision-making. High-precision maps can help cars perceive complex road surface information in advance, such as lane lines, slopes, curvatures, and headings, combined with intelligent path planning, allowing cars to make correct decisions. It can be seen that accurate lane lines or other road marking information in high-precision maps can help the generation of key traffic elements in high-precision maps, which is one of the important conditions for automatic dr...
