【摘要】：在穿戴腰式行人導(dǎo)航系統(tǒng)中,行人做彎腰、上下蹲等原地起伏動(dòng)作時(shí)會(huì)引起傳統(tǒng)峰值檢測(cè)法步數(shù)檢測(cè)誤差。為補(bǔ)償此項(xiàng)誤差,在對(duì)人體腰部運(yùn)動(dòng)特征分析基礎(chǔ)上,提出一種引入角速度信息輔助的行人步數(shù)檢測(cè)方法。此方法先提取人體前向、側(cè)向角速度信息來(lái)判斷行人是否前進(jìn),并聯(lián)合垂向加速度計(jì)輸出的峰值信號(hào),進(jìn)行組合步數(shù)檢測(cè)。在對(duì)27組引入原地起伏動(dòng)作的行走實(shí)驗(yàn)中,應(yīng)用峰值檢測(cè)法和本文方法檢測(cè)步數(shù)的平均準(zhǔn)確率分別是85.8%、98.84%。實(shí)驗(yàn)結(jié)果表明,提出的方法能有效減少原地起伏動(dòng)作導(dǎo)致的步數(shù)誤差,且具有較高的可靠性。
[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.
