摘要:本研究目的是通过人脸监测技术和压力测量来检测驾驶员的疲劳情况及时发出警告, 有助于预防交通事故的发生。在研究中,设计了一个系统通过面部监测技术和压力测量来检测司机的疲劳状态。提出的方法分为两步:检测驾驶员的生理表现和测量驾驶员的状态。生理性能可以通过使用一种力敏感的电阻器的压力测量来获取。第二步是通过图像处理完成的计算机视觉方法。计算机视觉方法捕捉图像,检测到驾驶员打哈欠和眼睛闭合的状态。从上述两个步骤中收集的结果与一种疲劳评估技术相结合,来判定困倦程度。提出了该算法,并对其进行了测试,结果表明,该算法能够有效地检测驾驶员的疲劳驾驶状态,通过预警提示系统可以有效防止路面交通事故的发生。

Abstract: the purpose of this study is to detect the fatigue situation of the driver by the face monitoring technique and the pressure measurement, which can help prevent the occurrence of traffic accidents. In the study, a system was designed to detect fatigue of drivers through facial monitoring techniques and pressure measurements. The proposed method is divided into two steps: detecting the driver's physiological performance and measuring the state of the driver. Physical properties can be obtained by using a pressure measurement of a force sensitive resistor. The second step is the computer vision method through image processing. The computer vision method captures images and detects when the driver yawns and the eyes are closed. The results collected from these two steps are combined with a fatigue assessment technique to determine the degree of sleepiness. The algorithm are presented, and the tested, the results show that the algorithm can effectively detect the driver's fatigue state, through the early-warning prompt system can effectively prevent the road traffic accidents.

疲劳驾驶是指驾驶员在经过长时间的连续驾驶后产生的精神和生理功能紊乱[1]。国际统计数据显示, 这是造成世界交通事故的主要原因之一。根据现有的统计数据, 每年有超过130万人死于公路, 20 至5000万人因交通事故而遭受非致命伤害[2]。根据警方的报告, 美国国家公路交通安全管理局保守估计, 每年共有10万辆车祸是驾驶员过度疲劳驾驶的直接结果。这些事故导致大约1550人死亡、7.1万受伤和125亿美元的金钱损失.每天大约八个人死在道路事故。实际死亡率可能会更高。……
