If you are familiar with math you can do it without a program, see for
example this lecture, note that it takes quite a bit of computer vision
jargon for granted:

If whatever you want to calibrate is a planar object and you are using

I'm pretty sure there are (or there used to be :-( ) other free programs for
camera calibration, just google it.
