本申请提供一种计步方法、计步装置及计算机可读存储介质。
实施例1
请参照图2,所述计步方法包括:
S100,获取加速度数据,所述加速度数据包括有效波峰;
其中,计步装置包括加速度传感器,所述加速度数据为所述计步装置的所述加速度传感器采集的数据。具体的,所述加速度数据为随着时间变化的波形数据,在用户佩戴计步装置进行动作时,加速度传感器接收到用户运动产生的加速度的变化,并且通过波形的方式进行表示。在用户移动过程中,用户通过左右手的交替摆动以及左右脚的依次移动实现行走,而在行走过程中,加速度传感器检测到的加速度数据呈周期性上下变化,因此可以根据所 述加速度数据对用户的移动状态进行判断,而当用户执行其他动作时,用户无法保持规律的波形周期性变化,因此计步装置可以根据波形的变化情况对用户的行走步数进行确定。
S200,获取当前有效波峰与上一次获取的有效波峰之间的时间间隔;
其中,当确定所述加速度数据存在有效波峰时,可以根据当前有效波峰与上一个所述有效波峰的时间间隔确定所述加速度数据的连续性,当相邻的两个所述有效波峰的时间间隔大于预设间隔时,表示所述加速度数据为非连续数据,因此无法采用上一个所述有效波峰对当前的所述加速度数据进行判断,当相邻的两个所述有效波峰的时间间隔小于或等于预设间隔时,表示用户正处于连续运动的状态,因此可以根据所述加速度数据对用户的计步信息进行进一步判断。
S300,当所述时间间隔大于预设间隔时,获取所述有效波峰的数据区域,直至下一个时间间隔大于预设间隔;
其中,当所述时间间隔大于预设间隔时,表示用户当前的运动状态相比于普通走步状态的运动频率更低,例如,当用户正在跳跃或是无规律移动时,所述计步装置记录的所述加速度数据的时间间隔会大于所述预设间隔,当所述计步装置检测到下一个所述有效波峰的时间间隔大于所述预设间隔时,确定所述数据区域为进行计步的所述数据区域。
S400,当所述数据区域内有效波峰个数小于所述预设值时,确定所述数据区域内有效波峰的特征信息;
其中,当所述数据区域内有效波峰个数小于所述预设值时,表示用户的移动步数未达到所述计步装置默认的计步条件,因此可以确定所述计步装置确定的所述数据区域内有效波峰个数对应的所述加速度数据,根据所述加速度数据确定对应的每个所述有效波峰的特征信息。
当所述数据区域内有效波峰个数大于或等于所述预设值时,表示用户在已保存的所述加速度数据中的有效波峰已经达到了预设值,依次可以按照正常的工作模式根据所述加速度数据进行计步。
S500,当所述数据区域内有效波峰的特征信息满足预设条件时,更新计步数据。
其中,在确定所述数据区域内有效波峰个数小于所述预设值后,首先确 定所述所述数据区域内有效波峰个数对应的所述加速度数据对应的有效波峰的特征信息,具体的,所述特征信息包括所述有效波峰的特征值与与上一个有效波峰的时间间隔,在一具体实施方式中,所述有效波峰的特征值为有效波峰的幅值。当所述幅值与所述时间间隔均满足所述计步装置的预设条件时,根据所述有效波峰更新计步数据。
本申请提出一种计步方法,所述计步方法包括:获取加速度数据,所述加速度数据包括有效波峰;确定当前有效波峰与上一次获取的有效波峰之间的时间间隔;当所述时间间隔小于预设间隔时,连续次数加一,切换至下一个所述有效波峰;当所述时间间隔大于预设间隔时,获取所述数据区域内有效波峰个数;当所述数据区域内有效波峰个数小于所述预设次数时,确定所述数据区域内有效波峰个数对应的每个所述有效波峰的特征信息;当所述数据区域内有效波峰个数对应的所述有效波峰的特征信息满足预设条件时,更新计步数据,重置所述数据区域内有效波峰个数为初始值,并切换至下一个所述有效波峰。当所述计步装置间断性的获取到所述加速度数据后,可以对所述加速度数据进行判断,从而对未达到计步条件的计步数据进行判断,提高所述计步装置的计步精度,解决了现有技术中计步装置在用户短时间移动时无法记录步数,导致计步精度较低的问题。
实施例2,
请参照图3,在实施例1中,所述步骤S200,之后还包括:
S600,所述时间间隔小于预设间隔时,连续次数加一,切换至下一个所述有效波峰。
其中,当所述时间间隔小于预设间隔时,表示用户当前正处于连续运动状态,因此可以记录当前的有效波峰,并将所述数据区域内有效波峰个数加一,每当一个所述有效波峰与上一个所述有效波峰的时间价格小于预设间隔时,确定连次数加一,而当所述时间间隔大于所述预设间隔时,表示用户从运动状态转变为停止状态,因此可以对所述计步装置更新的所述数据区域内有效波峰个数进行判断,并判断用户在连续次数对应的所述加速度数据内的计步状态。
实施例3,
请参照图4,在实施例1中,所述步骤S500,包括:
S510,当所述所述数据区域内有效波峰的特征信息满足预设条件时,根据所述有效波峰确定计步步数;
S520,重置所述数据区域内有效波峰个数为初始值,并切换至下一个所述有效波峰。
其中,当对所述数据区域内有效波峰个数对应的所述有效波峰与所述与所述预设条件对比完成后,表示所述数据区域内有效波峰个数对应的所述加速度数据已经完成处理过程,因此需要将所述数据区域内有效波峰个数重置为初始值,方便继续对后续的所述加速度数据进行,优选实施方式中,在将所述数据区域内有效波峰个数关联的所述加速度数据判断完成后,将所述数据区域内有效波峰个数重置为0。
在将所述数据区域内有效波峰个数重置为初始值后,所述计步装置对所述数据区域内有效波峰个数对应的所述有效波峰完成所述计步数据的更新,因此切换至下一个所述有效波峰,从而对后续的所述加速度数据进行计步处理。
在一具体实施方式中,所述计步装置的默认计步起始数值为10,那么当所述计步装置只有在检测到用户的移动步数超过10步时,才会开始执行计步操作,并更新计步数据。当所述计步装置检测到的有效波峰的数量为8个,未达到10个时,需要对8个所述有效波峰分别与预设条件进行判断,当8个所述有效波峰中的6个满足条件时,更新所述计步装置的计步数据,使记录步数增加6。
实施例4,
请参照图5,在实施例1中,所述步骤S200,包括:
S210,确定当前有效波峰的特征值以及所述当前有效波峰的所述特征值对应的特征时间点;
S220,当所述特征值满足第一预设条件,且所述特征时间点满足第二预设条件时,根据所述特征时间点确定当前所述有效波峰与上一个所述有效波 峰的时间间隔。
其中,为了确定相邻的两个有效波峰之间的时间间隔,需要首先确定两个所述有效波峰的特征值与所述特征值对应的特征时间点,具体的,所述第一预设条件为预设阈值,首先对两个所述有效波峰的特征值与所述预设阈值进行判断,当所述有效波峰的所述特征值大于或等于所述预设阈值时,表示所述有效波峰能够用作更新计步数据,在确定所述有效波峰的所述特征值大于或等于所述预设阈值后,根据所述有效波峰的所述特征值对应的所述特征时间点确定相邻的两个所述有效波峰的时间间隔。
在一具体实施方式中,所述加速度数据中包括5个所述有效波峰,在对5个所述有效波峰的特征值与预设阈值进行判断时,判断第一、第二、第三以及第五个特征值大于或等于所述预设阈值,而所述第四个特征值小于所述预设阈值,那么在计算所述时间间隔时,分别计算第一个有效波峰与第二个有效波峰的时间间隔、第二个有效波峰与第三个有效波峰的时间间隔以及第三个有效波峰与第五个有效波峰的时间间隔,而不计算第三个有效波峰与第四个有效波峰的时间间隔以及第四个有效波峰与第五个有效波峰的时间间隔。
实施例5
请参照图6,在实施例1中,所述步骤S400,包括:
S410,当所述数据区域内有效波峰个数小于所述预设值时,确定每个所述有效波峰的幅值以及相邻的所述有效波峰的时间间隔;
S420,根据所述幅值确定第一方差以及根据所述时间间隔确定第二方差;
S430,对所述第一方差与所述第一子预设范围以及所述第二方差与所述第二子预设范围进行判断;
S440,当所述第一方差位于所述第一子预设范围内,且所述第二方差位于所述第二子预设范围内时,根据所述数据区域内有效波峰个数更新计步数据,切换至下一个所述有效波峰。
其中,所述特征信息包括所述当前有效波峰的幅值以及所述当前有效波峰与上一个所述有效波峰的时间间隔;所述预设条件包括第一子预设范围以及第二子预设范围,在确定所述有效波峰对应的幅值及与上一个所述有效波 峰的时间间隔后,确定多个所述有效波峰的第一方差,以及根据多个所述时间间隔确定第二方差后,判断所述第一方差是否在第一子预设范围内,以及所述第二方差是否在第二子预设范围内。
在一具体实施方式中,所述加速度数据中包括5个所述有效波峰,5个所述有效波峰的幅值分别为0.9316、1.3542、0.924、1.1373、0.9559,5个所述波峰的相邻两个之间的时间间隔分别为26、27、27、29个样本点,计算所述第一方差为0.1858,所述第二方差为1.2583,当第一子预设范围为0.4,所述第二子预设范围为2.25时,所述第一方差小于所述第一子预设范围,所诉第二方差小于所述第二子预设范围,因此所述加速度数据中的5个所述有效波峰均能用户更新将所述计步数据集。
在可选的实施方式中,所述当所述有效波峰为第一个所述有效波峰时,所述时间间隔为所述有效波峰的特征时间点与参考时间点之间的时间间隔。具体的,当对多个所述有效波峰中的第一个所述有效波峰时,由于第一个所述有效波峰之前并不存在有效波峰,因此可以将第一个所述有效波峰的特征时间点与参考时间点进行计算,确定特征时间点与参考时间点之间的时间间隔,从而方便对第一个所述有效波峰进行判断。
在可选的实施方式中,当任一所述第一方差未位于所述第一子预设范围内时,表示所述第一方差对应的所述有效波峰不满足计步要求,因此切换至下一个所述有效波峰;当任一所述第二方差未位于所述第二子预设范围内时,表示所述第二方差对应的所述有效波峰不满足计步要求,因此切换至下一个所述有效波峰。

其中,当所述数据区域内有效波峰个数大于所述预设次数时,表示所述计步装置能够通过正常的方式对所述加速度数据继续检测,并根据所述加速 度数据更新数据,在通过所述加速度数据更新计步数据后,将所述数据区域内有效波峰个数重置为初始值,方便对后续的所述加速度数据进行判断。
