This is a dummy video I made by hanging my KAP rig from one of my trees and giving it a nice violent rolling motion. The original video was 60fps in made in 720HD. Not sure how it'll come out here.
Fair warning, this video is boring, and may cause motion sickness. This is not representative of how a KAP rig moves in the air. The purpose of the video was to introduce a clear periodic motion in one axis, and see how well Video Deshaker would pick it up.
The analysis stage of this is to run the video through Virtual Dub and Video Deskaher to get X, Y, and Z displacements on a frame-by-frame basis. Knowing the characteristics of the lens and detector, it's possible to translate Deshaker's X and Y pixel displacements and convert them to angular displacements. Since the frame rate is also known, these then translate into angular velocities for each of the three axes.
These are then fed into a Fast Fourier Transform routine to find if there are any dominant frequencies of oscillation. In the case of this video there is one very clear frequency since I'm treating the whole rig like a pendulum. But the question is whether the FFT will see it.
The results of the analysis can be found here:
