| 摘 要： | 实时检测机车乘务员的疲劳程度,是提高机车运行安全的有效途径.本文提出一个基于被动视觉的车载机车驾驶疲劳时实检测系统.系统通过CCD摄像头获取驾驶状态下机车乘务员的图像,然后运用图象处理技术进行人脸检测、眼睛定位等处理,并提取眼睛的闭合度作为PERCLOS疲劳检测的依据.针对实时图像处理数据量大、运算复杂的特点,采用TMS230DM 6437作为核心处理器进行了硬件实现.实验表明,系统能准确实时地检测驾驶疲劳程度,具有较好的实用性.

| Abstract: | The real-time detection for the locomotive drivers ’fatigue was an effective way to improve the security of locomotive driving.The Real-time Detection System of locomotive drivers ’fatigue based on passive vision was proposed in this paper.Firstly,the color images of the locomotive driver were captured by CCD camera.Secondly,face detection and eyes location in the captured images were processed,and then the eye closure degree was picked up for non-contact detection of the locomotive driver ’s fatigue based on PERCOLS.Thirdly,considering large data and complex operation,a hardware implementation based on TMS230DM 6437 was put into practice.The experiments were validated the effectively,reliability and practicability of the System. |
