温馨提示
matlab由频域变时域的代码活动识别使用加速度计数据 该项目的目标是根据3D加速度计数据对用户采取的操作(步行,爬楼梯和下楼梯)进行分类。 使用的工具 信号处理:Python,Numpy,Scipy和Matplotlib分类器设计:Tensorflow-Keras 输入数据读取 从提供的文本文件中读取输入数据。 输入数据在9个单独的列表中读取-climb_x,climb_y,climb_z,descend_x,descend_y,descend_z,walk_x,walk_y和walk_z。 然后,将这些数据进一步分为长度为70%的子列表用于训练,长度为30%的子列表用于测试。 这些数据文件是按随机顺序读取的,因此在训练过程中不会过度拟合数据。 前处理 时域中的原始数据图: 我们提供的信号具有许多嘈杂的频率成分。 因此,有必要使信号通过必要的滤波器并完善数据。 下图显示了时域中的原始训练信号数据。 曲线分别是爬升动作,下降动作和步行动作的X,Y,Z加速度幅度。 可以观察到,在爬升数据的情况下,除了样本数量6000以外,大多数信号都遵循一定的模式。经过调查,发现这是由于训练数据集所记录
