KNOW WHAT THE RESULT MEANS

This version reads extracted angle measurements; it does not decode or track shadows in uploaded video.
Moving cameras, moving objects, terrain and unreliable directional references can invalidate the model.
A conditional mismatch does not identify the reason for that mismatch or authenticate a video.
