Abstract

This paper describes a real-time prototype computer vision system for monitoring driver vigilance. The main components of the system consists of a specially-designed hardware system for real time image acquisition and for controlling the illuminator and the alarm system, and various computer vision algorithms for real time eye tracking, eyelid movement monitoring, face pose discrimination, and gaze estimation. Specific contributions include the development of an infrared illuminator to produce the desired bright/dark pupil effect, the development a digital circuitry to perform real time image subtraction, and the development of numerous real time computer vision algorithms for eye tracking, face orientation discrimination, and gaze tracking. The system was tested extensively in a simulating environment with subjects of different ethnic backgrounds, different genders, ages, with/without glasses, and under different illumination conditions, and it was found very robust, reliable and accurate.
