Hi,
I used ARToolkit to solve the following problem :
I have coplanar 4 or 5 3D points, and their 2D projection on the screen, and I want to find : position, orientation, and focal length of the cam.
I use ARToolkit by pasing directly 4 equations of the lines of a square projected on the screen (arGetLine). This is working fine.
But my problem is that I don't know any parameter of the cam (focal), and also that I don't necessarly have a square as pattern.
In fact, my problem is to find something like the Camera Match algorithm used in 3DSMax.
Any suggestion ?
