in the original Atlas 3D scanner, the lasers are about 5 inch from the camera, does it matter if I put them farther ? (7 inch)

Thanks a lot for your investigation, it makes that point clear.

About your convenient web interface, may I be permitted to suggest that I appreciate the threshold value to be on the camera page, because when you are testing about the right value it is necessary to change page for other values : in my view, it could be a little improvement.

Thanks again for your brilliant work.

For info, I've change raspicam and focus it to get best results but always get the shift between modes.
I use a raspberry 2 updated with the latest soft and, unrelated, a 0.9° stepper.

In 1.9M, the treshold level is hard to find with same light level as 5M still mode.

The question have been asked on the google group but the answer leave me hanging on.

I've tried 3 different resolution for calibration :
5M still mode gives this :

I've used it to center camera and both lasers.

Switching to 1.9M without changing anything gives that :

I found the same shift with the 0.3M resolution :

Uriah previously answer that the 5M VIDEO mode must not be used for the moment.
Is it true for both STILL and VIDEO mode in 5M resolution ?

I observe that when I calibrate with 5M still mode, my scan are OK but if I want to scan at 1.9M I need to recalibrate due to the shift : is it supposed to be like that ? Or am I wrong ?

Thank you to clarify this point.
