摘要
疲劳驾驶已成为交通事故发生的主要原因之一。文中提出了一种基于3G视频的人眼疲劳检测方法。通过DirectShow技术对视频流抓取视频帧,采用肤色聚性特征进行人脸定位,基于灰度信息进行人眼定位与追踪,并采用Perclos方法进行疲劳判断。通过此方法,可以及时了解驾驶者的疲劳状态,有效预防疲劳驾驶。
Fatigue driving has become one of the main contributing factors to traffic accidents.This paper presents a method for the detection of driver eye fatigue state based on 3G video.First,video frames are captured from the video stream via DirectShow,then the human face＇s position is located through the characteristics of skin colors,and the human eyes are tracked using grayscale information.Finally,the PERCLOS method can decide whether the driver is fatigue.By this method,it can prevent fatigue driving effectively.
