<![CDATA[VOXL 2 Stereo Calibration]]>Hi all,

Trying to do a stereo camera calibration on a VOXL 2 and getting pretty large re-projection errors when calibrating the extrinsics but okay error for the individual cameras. Followed the documentation for calibrating the cameras and sifted through the forums but can't seem to find a solution to this. Is there a step to calibrating that isn't specified in the documentation? or is there a best practice for doing these calibrations? Thanks!

I think I'm getting close. Im pretty consistently getting a reprojection error ~0.6 at this point so still have yet to successfully calibrate stereo extrinsics. Tried new stereo cams, refocusing, different lighting, different scales of checkerboards, but can't get sub 0.5

Sorry for the lag here, I'm cleaning up open topics and saw this message a bit late.... Any progress on this issue?
