Study on Vision Monitoring Techniques of Driver Fatigue and Loosing Alertness

Driver fatigue and loosing alertness are the major reasons of severe traffic accidents. Over the last ten years, there has been an increasing interest in the development of fatigue or loosing alertness detection devices. In these studies, the method based on vision has been a leading technique due to its characteristics. This paper presents a real time system which can alert drivers when they feel drowsy or lose alertness through monitoring the state of eyes, mouth and face orientation. Test results show that the system can monitor the face features effectively and realize warning based on specified rules.
