Abstract

The invention relates to a lane line detection method, and belongs to the field of automobile active safety. The method comprises the steps that (1) a camera captures a video image; (2) edge enhancement is performed on the captured video image; (3) a self-adapting threshold selection method is adopted for the image after being processed through the edge enhancement to calculate a binarized threshold, and a binarized image is obtained; (4) lane line inner side edge point extraction is performed on the binarized image; (5) partition Hought transformation is adopted for the extracted image data for fitting lane lines. In the method, a self-defining difference algorithm is adopted, so that the lane line edges are enhanced well, and the problem that in the prior art, an automobile has a traffic accident due to lane deviation is solved.

Description

technical field [0001] The invention belongs to the field of automobile active safety, and in particular relates to a lane line detection method. Background technique [0002] The rapid development of modern computer technology and the integration of new technologies such as multi-sensor technology and communication control theory have made it possible for the popularization and application of intelligent vehicle auxiliary driving systems, and driving intelligent vehicles will be safer and more comfortable. When faced with unexpected emergencies while driving, the intelligent assisted driving system can immediately provide auxiliary driving decisions, emergency braking or early warning, so as to maximize the safety of driving and minimize social and economic losses. The research scope of intelligent assisted driving is extensive, among which the lane departure warning (Lane Departure Warning, LDW) system, as an important main component of the modern intelligent traffic safet...
