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 present application relates to a data processing method and a storage medium for detecting lane lines. The method includes: obtaining the pixel coordinates of at least one lane line sample from the image according to a first preset rule, wherein the first preset rule is used to obtain the pixel coordinates in the y direction of the image; After the coordinates are converted into points in the coordinate system of the unmanned vehicle, multiple sampling point data are obtained; the multiple sampling point data are filtered according to the second preset rule to obtain the target sampling point set, and the second preset rule uses Filtering the non-target sampling points on the lane line under the coordinate system of the unmanned vehicle; performing curve fitting processing on the set of target sampling points, if the radius of curvature corresponding to the curve obtained by the fitting processing is greater than the preset threshold, Then output the lane line, otherwise give up the output. The data processing method and storage medium for detecting lane lines provided by the present application can provide high-quality lane line data 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...
