| 摘 要： | 驾驶员疲劳驾驶是引发交通事故的一个重要原因。针对驾驶疲劳检测算法运算复杂、视频图像数据量大的特点,设计了基于瞳孔几何特征的疲劳驾驶检测嵌入式系统。系统以TI公司的DSPTMS320DM642为核心,采用瞳孔图像的几何特征约束定位人眼,识别疲劳帧。在此基础上,提出了疲劳状况测评的判定方法,从而达到检测驾驶员疲劳程度的效果。实验结果表明,该系统算法简单、快速,是一种行之有效的、实时的非接触式疲劳驾驶检测系统。

| Abstract: | Fatigue driving is a major reason for the traffic accident.Aiming at the characteristics of fatigue detecting algorithm for complex operation and mass data of vedio images,a fatigue driving detecting embeded system,based on the geometric characteristics of pupil,is designed.With the TI's DSP TMS320DM642 as its core,the system can identify the fatigue frame by locating eyes in the pupils image with the geometric characteristics restriction algorithm.On this basis,the evaluatiing method for measuring the fati... |
