Abstract

The invention discloses a lane line detection method. The method comprises the following steps: preprocessing an image collected in real time; eliminating interference information on the lane line byadopting a morphological top hat operation for the preprocessed image; performing binarization processing on the image after eliminating the interference information on the lane line to obtain an initial lane line communication region; dividing the initial lane line communication region into an initial left lane line communication region and an initial right line communication region according tothe direction of the initial lane line communication region, and performing linear fitting on the initial left lane line communication region and the initial right line communication region by adopting RANSAC; and respectively performing boundary extraction on the optimal initial left lane line communication region and/or the optimal initial right line communication region after the RANSAC classification, performing B-spline curve interpolation fitting lane line processing on the extracted boundaries to obtain the final left lane line and/or the final right lane line.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a lane line detection method, device and computer-readable storage medium. Background technique [0002] With the development of social economy, vehicles have increasingly become an indispensable means of transportation for the public, and driving safety issues have become more and more important. Driver assistance systems are currently installed in many vehicles. Among them, some driving assistance systems can provide vehicles with driving lane information by detecting lane lines on the road. For example, as an important part of the Advanced Driver Assistant System (ADAS), the Vehicle Departure Warning System (Lane Departure Warning System, LDWS) can detect the lane information of the vehicle and warn the driver when the vehicle deviates from the lane. Initiate a warning prompt to ensure driving safety. [0003] The key to the lane departure warning system is...
