Hi,

Do you know something about the experiment of the "Optical Pendulum"?

	<https://www.youtube.com/watch?v=cDJZVWEvhrc>

A camera is suspended upon a cable, and an image is shot at the rest
position. Then you push the pendulum, so that the camera oscillates,
and new images are acquired when the pendulum moves.

The goal is to evaluate the eight parameters that determine the
position of the camera, from the rest position to the actual one.
Because the pendulum oscillates, we obtain a pseudo-sinusoidal.

The eight parameters are the perspective transform that happens
from an image, to the others. That means translations <Tx,Ty,Tz>
rotations <Rx,Ry,Rz> and two perspective parameters <Sx,Sy>.

That's what we can see in the above video. Each images, and the
corresponding perspective transform parameters, compared to rest.

Best regards,
