Kalman Filter for Moving Object Tracking: Performance

WebThe constant-velocity motion assumption is valid when the scan duration is short or the motion is gentle. But for very aggressive motions where the velocity may change during a scan, for example, in drone aerobatics, the constant-velocity method will often cause large drift or even failures in odometry.
