摘要
PERCLOS法能方便的对驾驶员进行实时、非接触式疲劳检测,在肤色检测的基础上结合眼睛的形状并利用梯度信息定位眼睛,通过计算眼睛的面积变化来确定眼睛的睁开、闭合状态,记录眼睛睁开闭合的次数及其开始、结束时刻,计算PERCLOS值,当PERCLOS值大于40%,眼睛持续闭合时间大于3s时,就认为驾驶员属于疲劳驾驶。
PERCLOS can make it easier for the driver to carry out real-time, non-contact fatigue testing,this article combining with the shape of eyes and Gradient information to locate eyes on the basis of the detection of complexion,and by calculating the change in the size of the eyes.Recording the number of opened and closed eyes and the value of PERCLOS,when the value is greater than 40%,sustain eyes to determine the state of closed or open beginning and the end moment,calculating the ed eye closure time is greater than 3 seconds, we can think the driver is in a drowsy state,belonging to fatigue driving.
