摘　　要：针对驾驶疲劳检测系统小型化、廉价和低功耗的实际需求,提出一个基于TMS230DM643的驾驶疲劳实时视觉检测系统。系统通过CCD摄像头获取驾驶员的人脸图像,采用TMS230DM643作为核心处理器,对获取的图像进行人脸检测、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。实验表明,系统能够准确实时地检测驾驶疲劳,具有较好的实用性。Real-time detection for the drivers＇ fatigue based on vision is the hot spot and tough problem in the research field.Aiming at the needs of small size,lower cost,and low power consumption,a real-time and vision detection system of drivers＇ fatigue based on TMS230DM643 was proposed in this paper.At first,the color images of the driver were captured by CCD camera.Then,TMS230DM643 as its core the captured images was processed as follows： face detection,and eyes location,and then the eyes＇ closure degree was picked up for non-contact detection of the driver＇s fatigue based on PERCOLS（Percentage of Eyelid Closure Over the Pupil Over Time）.The experimental results validate the effectiveness,reliability and practicability of the system.
