transbigdata.traj_smooth

transbigdata.traj_smooth(data, col=['id', 'time', 'lon', 'lat'], proj=False, process_noise_std=0.5, measurement_noise_std=1)

Smooth Trajectory Using Kalman Filter.

Parameters:

  • data (DataFrame) – Trajectory data

  • col (list) – Column names of the trajectory data

  • proj (bool) – Whether to perform equidistant projection

  • process_noise_std (float) – Standard deviation of the process noise

  • measurement_noise_std (float) – Standard deviation of the measurement noise

Returns:

data – Smoothed trajectory data

Return type:

DataFrame
