Compute acceleration data from positional data.

Parameters:

  • sampling_rate – Sampling rate of input time series.

  • degree – The degree of the polynomial to use.

  • window_length – The window size to use.

  • padding – The padding method to use. See savitzky_golay for details.

  • n_components – Number of components in input column.

  • position_column – The input position column name.

  • acceleration_column – The output acceleration column name.
