Problems solved by technology
[0004] However, due to the poor acquisition accuracy and sensitivity of the existing lane images, the results of judging the lane width and whether the vehicle deviates from the centerline of the lane based on the lane image are inaccurate, and it cannot be well realized for the driver's unconscious vehicle lane departure behavior. Discrimination and correction

The invention discloses a lane keeping system and a method thereof. The lane keeping system comprises a vehicle state acquisition assembly, a monocular camera and a vehicle state correction assembly,the monocular camera is arranged on a front windshield and is directly located in the rear of a rear view mirror, and the monocular camera is connected with the vehicle state acquisition assembly andthe vehicle state correction assembly; the vehicle state acquisition assembly is used for obtaining vehicle state information; the monocular camera is used for obtaining a lane image and the vehicle state information, according to the lane image, feature points of a lane marking line is extracted, the lane marking line is tracked, and mathematical model construction between a vehicle and the lanemarking line is established in sequence, whether the vehicle state needs correction or not is determined according to the lane image and the vehicle state information, and a vehicle state correction signal is sent to the vehicle state correction assembly when the vehicle state needs to be corrected; and the vehicle state correction assembly is used for correcting the vehicle state according to thevehicle state correction signal. The lane keeping system can realize the correction of the behavior of deviating from a driveway of a driver unconsciously.
Description
technical field [0001] The invention relates to the technical field of safety driving assistance, in particular to a lane keeping system and method. Background technique [0002] With the rapid increase in the number of vehicles, road accidents remain high. Behaviors such as speeding, not keeping in the current lane, and improper operation are all factors that lead to road traffic accidents. According to related reports, the proportion of road traffic accidents caused by vehicles not keeping in the proper lane or leaving the lane is second only to speeding. It can be seen that how to ensure the safe driving of vehicles in the current lane is an urgent problem to be solved. question. [0003] In the related technology, when the vehicle is driving, by collecting the image of the lane line, the width of the lane and whether the vehicle deviates from the center line of the lane are determined according to the image of the lane line. The driver can adjust the steering wheel of...
