Driving fatigue detection and early warning system and method based on vision

Abstract

The invention provides a driving fatigue detection and early warning system based on vision. The driving fatigue detection and early warning system comprises a face detection and identity verificationmodule, a normal driving baseline database module, a fatigue driving behavior detection module, a fatigue driving behavior early-warning module and a fatigue driving behavior management and control module; the face detection and identity verification module is used for collecting images of a driving cab and extracting face information and identity information; the normal driving baseline databasemodule is used for establishing and updating fatigue baselines of a driver; the fatigue driving behavior detection module is used for generating fatigue driving ROI based on the extracted face information, and conducting fatigue driving behavior identification; the fatigue driving behavior early-warning module is used for judging the driver fatigue state and the driving fatigue level according tothe monitoring results of the fatigue driving behavior detection module and issuing a fatigue early-warning signal for the driver; and the fatigue driving behavior management and control module is used for triggering driving data records and uploading data according to the fatigue early-warning signal.

Description

technical field [0001] The invention relates to the technical field of safe driving, in particular to a vision-based driving fatigue detection and early warning system and method. Background technique [0002] There are 500,000 traffic accidents in China every year, and the death toll due to traffic accidents exceeds 100,000. According to the statistics of road traffic accidents, more than half of the traffic accidents are caused by the driver's danger or wrong vehicle operation. However, most of these man-made accidents are caused by fatigue driving, so the intelligent analysis and early warning system of driving behavior has important application value. The active safety systems of existing passenger cars and commercial vehicles rarely have functions involving driver behavior analysis and reminders, especially for commercial transport vehicles, where long-term and long-distance driving leads to a higher probability of the above-mentioned fatigue driving. Most existing co...
