Abstract
Fatigue driving monitoring, reminding and early-warning method and system based on computer vision are provided. The system includes: a fatigue real-time monitoring system for identifying fatigue characteristic postures of a driver and obtaining a fatigue level according to frequencies of the fatigue characteristic postures and a driving time; a fatigue automatic reminding system for receiving the fatigue level, obtaining a vehicle real-time position information and providing the driver with a corresponding grade of reminder according to the fatigue level; and a fatigue information early-warning system for receiving the fatigue level and the vehicle real-time position information to obtain a fatigue safety index, so that a cloud map of fatigue road conditions is obtained according to the fatigue safety index and shared with traffic management departments and drivers for early-warning. It reduces the situation of fatigue driving on freeway and the hazard of traffic safety accidents caused by fatigue driving.
