基于眼部行为的驾驶疲劳监测方法

Eye Statebased Fatigue Drive Monitoring Approach

摘要:

为了克服percentage of eyelid closure(PERCLOS)法作为疲劳监测方法对仪器要求过高的弱点,通过室外行车实验验证其实时监测的适用性的同时,在室内以眨眼次数和闭眼时间为主要实验分析研究对象,检验两者的数值与驾驶疲劳程度之间的关系以开发新的疲劳监测指标.通过实验分析结果论证PERCLOS实际应用的可能性,眨眼次数与闭眼时间作为驾驶疲劳眼部行为的评价指标的有效性和应用价值.

Abstract:

Considering the percentage of eyelid closure (PERCLOS) method requires too much in equipment as a fatigue monitorig method, an outofdoor experiment was set to check out whether the PERCLOS method was feasible in real-time monitoring, and a laboratory measurement was set to test the availability of other eye states indices such as the frequency of blink and how long all blinks lasted, in order to find out more indices to monitor fatigue drive. Based on the results of the experiments, the possibility of using PERCLOS method in real-time is discussed and the relativity between the new indices and the degree of fatigue is validated.
