Adjustment of the projector focus 

During the scanner operation the projector project structured light to the object - coded 
lines and stripes. To ensure that the lines are sharp, the projector must be focused on 
the working distance of the scanner. 
By switching the mode "Lines and Stripes", adjust the focus of the projector, so that the 
lines on the calibration plate were as sharp as possible. Check and if it’s necessary to 
adjust the projector focus. 
 

 

 

 

Bringing the cameras together 

For the work of the scanner it is necessary to point both cameras to the same position 
on the specified working distance. Install the calibration plate in front of the scanner on 
the found working distance (if you changed its position after the projector focusing 
procedure).
