摘要: 传统基于生理学的人体疲劳检测方法存在周期较长、准确度较低的问题。为此,提出一种基于步态加速度特征的人体疲劳状态检测方法。通过微机电传感器加速度计采集被检测人的步态加速度数据,给出基于相关系数法的步态疲劳状态阈值判断方法。实验结果表明,9个样本的检测准确率为93.06%,准确率较高,时间复杂度较低。

Abstract: Traditional physiology human fatigue detection methods have the problems that the time is long and accuracy is low. Aiming at this problem, this paper proposes a novel method for human fatigue identification based on gait acceleration. Collecting gait acceleration data by using a Micro Electro Mechanical Sensor(MEMS) triaxial accelerometer, based on correlation coefficients, the method proposed in this paper can be used to identify human fatigue. Experimental results show that the accuracy of identification is 93.06% with 9 test subjects, and this method has the advantages of calculating time and accuracy.

Key words: gait acceleration, human fatigue, correlation coefficient method, Micro Electro Mechanical Sensor(MEMS)
