摘要:
A gait waveform feature extracting method and an individual identification system extract features of the gait waveform. A one-step waveform corresponding to one step of a walking movement is specified using, as an index, a peak amplitude corresponding to a state where substantially a whole bottom surface of one foot is in contact with the ground and a toe of the other foot is just after leaving the ground among the electric field displacement formed on the human body in accordance with the human body's walking movements. Based on the specified one-step waveform, the features of the one-step waveform are extracted, so that the peak amplitude appears without influence from electric-charge interference between the right and left legs. Accordingly, the one-step waveform reflects the actual one step of the walking movement, and therefore, the features of the one-step waveform can be precisely extracted.

步态波形特征提取方法和个体识别系统提取步态波形的特征。 使用与步行运动的一个步骤相对应的一步波形,使用对应于一英尺的大致整个底面与地面接触的状态和另一脚的脚趾的状态的峰值振幅作为指标 就是在人体的走动动作之后离开地面离开人体形成的电场位移。 根据指定的一步波形,提取一步波形的特征,使得峰值振幅不受左右腿之间的电荷干扰的影响。 因此,一步波形反映了步行运动的实际一步,因此,可以精确地提取一步波形的特征。
