基于多参数的驾驶员疲劳检测系统

疲劳驾驶已经成为威胁驾驶员安全的重要因素.本文设计了一种融合眼睛状态和心跳速率变化的驾驶员疲劳检测系统,分别研究了驾驶员疲劳时眼睛状态和心跳速率的变化规律,改进了已有的疲劳检测算法以适应驾驶环境.由于融合了眼睛检测子系统和心跳速率检测子系统,该系统既减小了光照等环境因素的影响,又克服了心跳速率检测设备有延迟的缺点,具有更好的准确率.实验结果证明该系统具有良好的鲁棒性和实时性.

Driver Fatigue Detection System Based On Multi Parameters

Fatigue driving has become a vital factor which threats the safety of drivers. This paper designed a driver monitoring system combined both status of eyes and changes in heartbeat rate. It respectively studied the status 9f eyes and the variation of heartbeat rate when the diver is fatigue and improved the existing fatigue detection algorithms in order to adapt the driving environment. Because of combining both eyes detection subsystem and heartbeat rate detection subsystem, the whole system can not only overcome the effect from environmental factors, such as Iight condition, but also over- come the shortcoming that heartbeat detection device has delay when detecting and communicating, so this system has a better accuracy. The experimental results suggested that the system has good robustness and real -time.
