基于模糊识别的驾驶员疲劳检测

摘要

Traffic accidents are mostly caused by the fatigue of a driver,the degree of which can be judged by monitoring the driver’s eyes. Based on a fuzzy recognition algorithm and by detection and operational analysis of the opening degree of a driver’s eyes,blinking frequency and the duty cycle of eye - closing duration,a method of distinguish the fatigue state of the driver’s eyes was proposed. Experimental results show that the proposed method can effectively identify a driver’s fatigue state with high accuracy and instantaneity.%汽车驾驶员疲劳驾驶是导致交通事故的重要原因之一，通过监测驾驶员的眼睛可以判别驾驶员的疲劳程度。对驾驶员眼睛的张开程度、眨眼频率、闭眼持续时间占空比等状态量进行检测和运算分析，提出利用模糊识别算法判别驾驶员眼睛疲劳状态。实验结果表明，该方法能有效识别驾驶员的疲劳状态，实时性好，准确率高。
