摘要
本文设计的驾驶员疲劳检测报警系统采用基于TMS230DM642的第二代高性能多媒体处理器,实现了非接触的、实时驾驶员疲劳状态监测。系统通过基于肤色信息的方法从获取的视频图像中检测人脸的位置,然后采用基于灰度值的方法精确定位人眼,提取眼睛闭合度,采用PERCLOS的PM80标准,实现对驾驶员疲劳与否的判定。
This paper designs a driver fatigue detection alarm system which adopts the second generation high-performance multimedia processor TMS230DM642.1t realizes the contact real-time driver fatigue detection.First, he system captures a picture：from the video stream,then the human face,s position will be located by the characteristics of skin colors,and the human eyes are tracked using grayscale information,and the eye closed degree can be collected.Finally,the PM80 stand of PERCLOS is used by the system to judge .whether the driver is fatigue.
