also here a problem with the inaccuracy of the tracking, you will have
the same issue with ARToolKit. Try another tracking plugin, calibrate
your camera, activating distortion correction for the video (i can
notice the radial distortion of your camera, can have a complimentary
correction on the visual incorrect alignment).
