Monocular Aptitude Lane Departure Warning System Design

Lane Departure Warning System(LDWS) is a car safety assist systems,following the capsule of the safety,whose main task is to extract lane markings and make warning-decision.In this paper,the lane departure warning system hardware architecture is designed based on TMS320DM642 which acts as the central processing unit.The algorithms turn the image into grayscale,and then detect the image's edge information,in the end set the region of interest(ROI) on the image.Hough transform based on phase grouping is used to extract the lanes,and according to the lane departure warning conditions,the system analyzes whether the warning should be presented or not and gives the driver warning singles when it is unconscious.The experiments results proved that the system will make warning in 2.5 s before the traffic accident,which implements the aim of the real-time,reliable lane departure warning.
