Abstract:

Helicopter flight path trajectories in approach to a tactical landing aid were monitored, ad hoc, by two cine cameras. Post-trial trajectory reconstruction using simple triangulation methods was confounded by the presence of an unknown bias error in the orientation of one camera, and by non-synchronous camera timing. This report describes the concept, formulation and implementation of an optimisation method which pools all data for a trajectory, permits extraction of bias terms, and yields a complete trajectory smoothed in space and time.
