Hi Tibor,

Motorized or hand held laser?
Please post a screenshot of the laser on the object.
Use smaller patterns to show DAVID more markers to do the cam calibration.
Did you solve your "jumping line" issue with the Basler cam?

Hi Tibor,

I Would love to help you but i have no experience with laser scanner.
For the same distortion in SLS i would suggest to change the position of camera (top, down, left, right of projector). but no idea about the laser.
But as Gunter suggested, I think you need to use a smaller calibration scale, so that you can have the whole image in your camera.
and another thing i guess is related to the camera resolution. try lower and higher resolution with different frame rate and exposure time.
You have Gunter here, dont worry. just do exactly what he asks and the problem will be discovered.

Regards,

Hi Gunter
The laser goes Mach3 stepper motor controller in a PC running XP Professional. The other PC is running Win7 32 bit David. Two completely independent machine. The Basler camera jump around the entire software re-installation solved. We do not charge David with Mach3, it runs on another machine. I have a suspicion the laser is not uniformly moving object but the small jumps. This Aroof But people slow down.

Hi Tibor and anybody out there,

it seems we need some pipeline to understand eachother.
Which languages do you know?
Is there anybody out there to do some translation to Hungarian? (please contact me via PM)

I'll try to catch your problem without using any language (but global ones - I hope) tomorrow....

Hi Gunter
I got a Hungarian user help, he has Basler camera.
Tough not to be used for certification. Now I'm trying.

Seems your laser is moved to fast.
OR:
Your stepper+gear does not give enough resolution ( = steps per round)

Hi
A 28 mm diameter coins continue to acquaintance the Basler camera.
1280x960 resolution, frame rate 14, span 66 mm panel size. Laser line speed of the lowest I can set. Improved a lot of noise, but the result is still very bad.
Dusting spray white surface.Mozart had been drinking and was head. :lol:
