【摘要】：在穿戴腰式行人导航系统中,行人做弯腰、上下蹲等原地起伏动作时会引起传统峰值检测法步数检测误差。为补偿此项误差,在对人体腰部运动特征分析基础上,提出一种引入角速度信息辅助的行人步数检测方法。此方法先提取人体前向、侧向角速度信息来判断行人是否前进,并联合垂向加速度计输出的峰值信号,进行组合步数检测。在对27组引入原地起伏动作的行走实验中,应用峰值检测法和本文方法检测步数的平均准确率分别是85.8%、98.84%。实验结果表明,提出的方法能有效减少原地起伏动作导致的步数误差,且具有较高的可靠性。
[Abstract]:In the wearable waist type pedestrian navigation system, when pedestrians bend down, up and down squat and so on, the traditional peak detection method will result in the detection error of the step number. In order to compensate this error, based on the analysis of the motion characteristics of the human waist, a method of pedestrian step detection with the aid of angular velocity information is proposed. The method first extracts the forward and lateral velocity information of the human body to determine whether the pedestrians advance or not, and combines the peak signal output from vertical accelerometer to detect the combined steps. In the walking experiments of the 27 groups, the average accuracy of the peak detection method and the method of this method is 85.8% and 98.84% respectively. The experimental results show that the proposed method can effectively reduce the step error caused by the undulating action and has high reliability.
