Abstract

The present application provides a lane line detection method and device, which relate to the technical field of image processing. The method includes: obtaining a binarized image of an image to be detected, and detecting a straight line on the binarized image; The depth parameter of the pixel point, the depth parameter is used to represent the distance of the physical point in the monitoring scene corresponding to the pixel point relative to the camera; according to the depth parameter, determine the depth range and the distance used to represent the length of the straight line It represents the depth distribution of the point distribution on the straight line; if the depth range satisfies the first set condition and the depth distribution satisfies the second set condition, then the straight line is determined to be a lane line. By applying this method, the efficiency of lane line detection and the accuracy of lane line detection results can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a lane line detection method and device. Background technique [0002] The lane departure warning system can assist the driver to reduce traffic accidents due to lane departure by means of an alarm, and in the workflow of the lane departure warning system, lane line detection and recognition is a particularly important link. [0003] In the prior art, the lane is mainly identified from the road image captured by the vehicle camera by using the straight line characteristics of the lane. Specifically, the road image can be binarized to obtain a grayscale image, and the Hough line detection method is used in the Straight lines are detected on the grayscale image, and then the detected straight lines are screened through the two parameters of straight line distance and angle to determine a straight line representing a lane. [0004] However, in actual situations, ...
