David camera calibration vs Open CV

Postby pognibene » Tue Mar 06, 2012 8:53 pm

Hi all,
It looks like David camera calibration is based on the Tsai model, or a derivative of it.
Values produces in the calibration XML file look very similar to Tsai parameters indeed.
I'm pretty sure somebody around played with Open CV, that integrates some support for camera calibration as well (but not based on a 90° corner, rather on a flat checkerboard).
Are Tsai intrinsic coefficients produced by David the same than what I would get with Open CV? Is the Open CV calibration more accurate than David's one, or the opposite?

Ok, that's a bit off topic and maybe an internal implementation detail, but still an answer would be interesting.

Thank you all for your help.
