Emne: Re: [ros-users] camera_calibration
I checked out latest and had to do a small bit of changes to sync the
timestamps of the two cameras whenever frames have very close
timestamps. So they aren't EXACTLY synced, but VERY closely synced. I
can try to send you a screen shot of the output. Note, I am testing
this with a quite small checkerboard (your checkerboard, but with 26mm
squares). Maybe that's the problem? Maybe I'm sampling a space too
close to the cameras?
