Research on gait recognition technology based on fiber array sensor

摘要:

为了实现根据步态特征进行个人身份识别和医学特性参数的修正,开发研制了一种新型点阵式的光纤压强传感器。利用聚合物海绵材料,将作用在传感器上力的变化转变为输出光纤的能量变化,并通过对传感器获得列阵数据进行细化,以压强分布"积分中心"的时空变化为信息特征,分析研究人体在不同运动过程中为保持动态平衡而产生时空变化的规律,从而实现步态识别研究。通过单体辨向、统计实验测试,100人次的测试正确率高于95%。 更多还原

Abstract:

To realize the recognition of personal status and the amendment of medical parameter according to gait characteristics,a new optic array pressure sensor was developed.When the sensor was pressed,the output energy of fiber would be changed by using polymer sponge material.Through thinning the array data from the sensor,the temporal and spatial variations for the integral center of pressure distributon were adopted as information features.After analyzing and researching the temporal and spatial va...
