What precision do you get with stereoCalibrate?

edit

Hi Guys,

I have a stereo rig that I am trying to calibrate but I am having trouble with my precision. I would therefore ask what level of precision is normal when working with stereo calibrate. I feel that my results are constantly 10 degrees off directionwise and a couple of centimetres translation wise. Im using a 6*8 checkerboard with squares around 22mm. The dataset I am working from is around 50 pictures.

What results have you achieved using stereo calibrate?

I am using an external model for the lens distortion (Ocam_calib) so I am passing in idealised coordinates and fixing the intrinsics matrix. This might be the source of my problem, but I am seeking other sources as well.

Any ideas?

Kind regards

Jesper
