Lateral motion tracking with yaw

I’m doing some very careful testing before I set Hermione loose live to fly in a circle.  This morning, I’ve confirmed the video lateral motion block tracking is working well.

For this first unpowered flight, I walked her forwards about 3m and then left by about the same.  Note that she always pointed in the same direction; I walked sideways to get the left movement:

Forward - Left

Forward – Left

For this second unpowered flight, again, I walked her forwards about 3m, but then rotated her by 90° CCW before walking another.  Because of the yaw, from her point of view, she only flew forwards, and the yaw is not exposed on the graph.  This is exactly how it should be:

Forward - Yaw 90° CCW - Forward

Forward – Yaw 90° CCW – Forward

So I’m happy the lateral motion tracking is working perfectly.  Next I need to look at the target.  I can go that with the same stats.

The only problem I had was that the sun needs to be shining bright for the video tracking to ‘fly’ above the lawn; clearly it needs the high contrast in the grass when sunlit.
