嵌入式驾驶疲劳检测系统设计

Embedded Driving Fatigue Detection System Design

随着机动车交通事故数量的快速增长,交通安全已成为研究的热点。疲劳驾驶是引起交通事故的一个关键原因。为了减少疲劳驾驶带来的损失,论文利用TI公司的DSP芯片TMS320DM642,设计了嵌入式驾驶疲劳检测系统。该系统集图像采集,图像处理,图像识别以及疲劳预警于一体。实验结果表明此设计能进行实时疲劳检测,可以有效地减少交通意外,并具有尺寸小,成本低,实时好的优势。

With the rapid growth of the number of motor vehicles traffic accidents,traffic safety has become a research hot⁃spot.Fatigue driving is a key cause of traffic accidents.In order to effectively avoid the loss caused by fatigue driving,this paper us⁃es TI's DSP chip TMS320DM642 to design the embedded driving fatigue detection system.The system integrates image acquisition,image processing,image recognition and fatigue warning.The experimental results show that this design can detect fatigue in real time and can effectively avoid traffic accidents caused by fatigue driving.Moreover,the system is small in size,low in cost,and good in real time.
