驾驶员眼睛疲劳状态检测技术研究
摘要
在判断驾驶员疲劳状态时
应首先对眼睛进行精确定位
再根据眼睛面积的减小程度、持续闭合的时间、闭合频率来判断眼睛疲劳状态。在进行人眼定位时
采用在RGB空间进行肤色分割、去除与边界连通的区域的方法
再结合形状验证法逐步减小眼睛区域候选范围
然后
计算眼睛区域的面积、持续闭合时间。实验证明:这种方法在定位人眼时
简单快速
且不受人脸背景、人脸肤色、姿态的影响。
Abstract
Locating driver’s eyes exactly firstly to judge driver’s eye state.Then by counting eye area and area’s reduction extent
noting eye’s continual closure time and closure frequency to detect driver’s eye fatigue state.Secondly
by skin color segmentation in RGB space
removing the object connected to the border and minishing the range of eye area gradually together with shape validation to locate driver’ eye
and then the eye closure times and time are computed.The test proves this method is simple and fast
