摘要
根据驾驶室的特定环境,给出了一个基于肤色模型和灰度积分投影的驾驶员疲劳检测系统.该系统首先利用肤色模型粗略检测出人脸区域;然后根据驾驶员面部几何特征,利用灰度积分投影法对驾驶员眼睛进行准确定位;最后根据上下眼皮距离及闭眼持续时间对驾驶员疲劳状态做出判定.仿真实验表明:该系统可以准确定位驾驶员眼睛,并对驾驶员疲劳状态做出判断.
According to the cab＇s specific circumstances, a driver＇s fatigue detection system is proposed in this paper based on skin-color model and gray integral projection. This system firstly detects the face region roughly using skin-color model. Then the driver＇ eyes are located exactly by face geometry features and gray integral projection. A judgment of the drive＇ s fatigue condition is made according to the distance of eyelid and the duration of driver＇s eyes closing. Simulation results demonstrate that this system can exactly locate drive＇ s eyes and make a judgment of the drive＇ s fatigue condition.
