interpolate 

interpolate(trajectory: Trajectory, timestamps: list | ndarray, method: InterpolationMethod = LINEAR, inplace: bool = True) -> Trajectory

Interpolates a trajectory to specified timestamps using the given method.

Parameters:

  • trajectory (Trajectory) –

    Trajectory to interpolate

  • timestamps (list | ndarray) –

    Interpolation timestamps

  • method (InterpolationMethod, default: LINEAR ) –

    Interpolation method. Defaults to InterpolationMethod.LINEAR.

  • inplace (bool, default: True ) –

    Perform in-place interpolation. Defaults to True.

Returns:

  • Trajectory ( Trajectory ) –

    Interpolated trajectory
