| 摘 要： | 对常用识别技术进行了综合和改进,最后达到了准确度高,受背景影响小的效果.所引入的疲劳判断系统采用PERCLOS方法来判断人是否处于疲劳状态,即通过摄像头读入人脸图像,然后对图像进行分析,以实现对人脸的识别,眼睛状态的判断.通过统计一段时间内的开闭比例来达到判断人是否疲劳的目的.

| Abstract: | Face recognition technology is a very popular topic recently,a new fatigue judging system for face recognition and dynamic track is introduced.As for the face recognition,in order to be more precise and avoid being interfered by the background,we employ a new method which has synthesized and improved the old ones is enployed.To do effective detection of fatigue,the PERCLOS method is adopted,which extracts the facial images by cameras,track and analyze the state of eyes and pick-up characteristic parameter of eyes,count closing time of eyes in succession within regular hour,judge the tired degree. |
