Implementation of fatigue driving warning system based on computer vision
Fatigue driving greatly reduces the reaction ability and judgment of drivers,and becomes a major hidden danger to traffic safety.Aiming at the shortcomings of fatigue driving warning,this paper design and implement a fatigue driving warning sys-tem based on computer vision technology using three-tier system architecture.Firstly,the lane markings on both sides of the road are detected,and lane departure warning is implemented based on the change in the angle between the driving direction and the lane direction;Secondly,key points of eye features are detected,eye fatigue warning is implemented based on the duration of eye closure;Once again,key points of mouth features are detected,yawning fatigue warning is implemented based on changes in the as-pect ratio of the mouth;Finally,based on historical fatigue driving data,the prediction of vehicle fatigue driving behavior is achieved.Through the use of this system,early warning of fatigue driving behavior can be achieved,so as to effectively improve traf-fic safety and reduce the risk of traffic accidents.
