David5 SLS3 Stereo calibration at 30mm

[CMcFadden]

Howdy all - just got a brand new David5 / SLS3 stereo setup.  We haven't been able to successfully calibrate with stereo cameras on the 30mm calibraiton pattern.  We can do the other patterns just fine, but can't seem to successfully get the 30mm calibration targets well enough in view for both cameras, even when the cameras are right up against the projector on the rail.  Are there any tips for making that work?

Try to use negative corner. I have more success with negative corner and 30mm scale. I am not sure how it´s going with two cams.

We can't seem to make it work with the dual cameras on a negative corner. It actually seems even worse than positive.

Sometimes I use the calibration pattern turned 90degree, so that one glassplate lies on the table. Maybe that works better for you? At which horizontal angle are the cameras set?

That's an interesting idea - I'll give that a shot.

We've tried a variety of horizontal angles.
