Hi All-
I am experimenting with different forms of camera calibration.
How can I translate the following set of camera calibration parameters into
an ARToolKit binary camera calibration file:
The list of internal parameters:
1. Focal length: The focal length in pixels is stored in the 2x1 vector fc.
2. Principal point: The principal point coordinates are stored in the 2x1
vector cc.
3. Skew coefficient: The skew coefficient defining the angle between the x
and y pixel axes is stored in the scalar alpha_c.
4. Distortions: The image distortion coefficients (radial and tangential
distortions) are stored in the 5x1 vector kc.
Is there a reference out there which describes exactly what camera
calibration file contains?
Thanks,
Abhilash.
