已有的眼睛状态识别方法不仅计算量大，而且易受环境因素(如光照条件)的影响。为此本文提出了一种新的眼睛状态识别方法:首先对实时拍摄的图像利用运动信息和肤色特征进行人脸检测 然后在检测到的上半部人

脸区域采用Adaboost算法只检测驾驶员正常状态下睁开的眼睛，把检测

的眼睛与眉毛分割出来制成正常睁开眼睛模板 最后把眼睛模板与未检测

到眼睛的上半部人脸区域进行匹配，当该区域的最大相似度值小于某闽值

时认为眼睛是闭合状态，否则认为眼睛是睁开状态。并根据眼睛状态计算

眼睛平均闭合时间和PERCLOS值，与事先设定的疲劳闽值进行比较判断出

驾驶员的疲劳状态

-Driver fatigue is very dangerous condition created when a person is suffering symptoms of fatigue while driving, often resulting from the hypnotic (Inducing sleep　soporific or hypnosis) effect especially during nighttime (peak levels at night can be 10 times daytime levels) driving either falling asleep at the wheel or so exhausted they made serious – and fatal – driving errors.
