摘要
为了降低手机位置不同以及行人运动状态不同对计步结果的影响,设计了一种基于手机加速度传感器加分减分机制的计步算法。该算法的基本思想仍然是对行走过程中的峰值进行检测,针对可能存在的多峰值情况,不再简单地依赖于某一个阈值,而是通过计分机制最大程度地消除多峰值的影响。该算法的关键是计步窗口大小的设定和计步策略的设计,最后通过试验验证了算法的有效性。
This paper designs a kind of algorithm of counting steps which is based on the plus and deduction mechanism of mobile acceleration sensor.The basic idea of the algorithm is still detecting the peak values in the process of walking.However,considering that there may exist many peak values,the algorithm in this paper doesn＇t simply rely on a certain threshold,but eliminates the affect of peak values to the largest extent through scoring mechanism.
