Abstract: The authors proposed a real time driver fatigue detection algorithm based on Adaboost. The algorithm is applied in an on-board embedded system to monitor driver’s status with infrared camera and active IR lamps. Face detection method is used to localize the eyes of the driver and the eye region is extracted to monitor the movement of eyelids. An alarm rule is designed based on the PERCLOS standard to detect drowsy driving. The algorithm is transplanted from PC to embedded platform and optimized by experiments. Several versions of on-board embedded system are designed and manufactured to test the algorithm, it can provide above 92% accuracy and under 1.5 s reaction time in real driving scenarios. The experiments show that the system is stable and it is available for commercial use.
