Hi,

The experiment from Hernan Badino was redone. You can see it there...

The main interest is that video is looping, and the result is almost:

Well, Hernan Badino is moving his head when he is walking, so the
reconstructed trajectory is not perfectly looping at the end. But
we can reconstruct the movement almost perfectly. We use OpenCV
for image processing, and POV-Ray for 3D representation. We have
to determine projective dominant motion in the video with a
reference image, and change it when correlation drops below 80%.

We have a 3D inertial model of motion, that's why POV-Ray helps =)

Best regards,
