基于信息融合技术的驾驶员疲劳度实时监控系统

Fatigue Driving Status' Monitoring System Based on Information Fusion Technology

疲劳驾驶是造成交通事故的重要原因之一。本文提出并实现的驾驶员疲劳度的实时检测系统,是利用红外线摄像仪和脉冲发光二极管相结合,对驾驶员眼睛进行快速定位和处理,分析出瞳孔变化趋势和眼睛眨眼次数;通过角速度传感器检测汽车的转向。将这些信息进行信息融合,从而实时、准确地监测驾驶员的疲劳度,并能分别给予不同程度的警告。

Driver fatigue is an important cause of traffic accident. We present and realize a system which can be used to monitor driver＇ s fatigued status and alarm. In order to improve the processing capability, it adopts video - disposing system consists of infrared camera and DSP, which can simultaneously monitor drivers＇ pupil size and blinking. At the same time, angle velocity sensor was used to detect the driving direction. The veracity of system will be strengthened to judge the drivers＇ fatigue driving status through information fusion technology
