Enhancement of video analysis methods

1) The video analysis method was applied to a new system. A new mechanical device with a perspex dome was designed and manufactured for mounting the video camera at the vehicle. The video results have been an important source not only for acquiring the relative motion between parafoil and load, but also for getting valuable information about the opening sequence and general parachute and parafoil behavior.

2) For the analysis of the relative motion a proven and state-of-the-art tracking algorithm was used. As output the relative yawing angle and the relative displacement in x- and y-direction was extracted. The displacements were transformed into relative attitude that was used successfully for the correction of the measurements in the load. The corrected data represents the real motion of the canopy.
Using the corrected data instead of the raw data from the load, better results for the parafoil aerodynamic model identification can be expected.

3) The new approach for the post-flight acquisition of the sideslip angle from video measurements of a textile vane did not work as expected. The main problems were poor visibility, partial obstructions and the high frequent fluttering of the textile vane that could not be resolved by the video. For the future this concept will be discontinued.
