An Optimisation Method for Reconstruction of Flight Path Trajectories from Non-Synchronous Time-Sampled Observations by Two Cine Cameras.
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. Keywords: Optimization; Least squares; Flight paths; Landing aids. (Australia)
