Hi everyone,
I just managed to calibrate my Gweike Cloud CO2 Laser with the dot pattern.
Unfortunately the result has some shifts of 0.5mm - 1.7mm within the alignmentpoint area (1-4).
I think the lens distortion might be not that accurate due to the hand held plate during the process and wanted to try out the new tag tracking function. But for some reason the green rectangles are not showing up with the build in camera. I tried with a different wide angle webcam and it immediatelly recognized the tags. But on my screen I can also see the tags very clearly with the build in camera.
So basically the question is: What technical requirement is needed for the camera to let lightburn recognize the tags, because as said from a humain eye, I see the tags clearly on both cameras.
I tried also to tweak the system setting for this camera around in windows (e.g. sharping, contrast etc) but without any luck. Is there any parameter that can be changed in order get it working also with lower resolution (in case this would be the technical requirement)
For completness, the build-in camera is I guess a 5MP camera with low refresh rate. The other camera that was working fine is a 2k (according to aliexpress) with a much better refresh rate (much more responsive).
This is how it looks like: No tags detected here 
When zooming is, it is still quiet good to recognize at least for a human eye:
Thank you all for your help
