摘要
将ARM+DSP技术应用于驾驶员的疲劳检测,使用S3C2440作为核心处理器,利用TMS320DM642作为视频采集处理模块,详细讨论了硬件平台与接口的设计。提出了一种简单有效的基于眼部特征的疲劳驾驶检测算法,结合单目机器视觉实现了驾驶员眼部睁闭状态的有效判定和疲劳驾驶的实时检测。在沪宁高速南京段的实验结果表明,该算法的实时性与精确性可以满足安全行驶的要求。
The ARM＋DSP technology is used to detect the fatigue driving for the drivers. S3C2440 is used as the core processor, TMS320DM642 is utilized as the video capture and processing module, and the design of the hardware platform and the interface is discussed. A simple and effective fatigue driving detection algorithm based on eye feature is proposed to realize the judgement of open-close state of eye and the real-time detection of fatigue driving. Experiments conducted on Hu-ning highway show that the algorithm is fast and accurate for the safety of driving.
