I am experiencing some difficulties in setting up my camera for robot generated grid calibration. I have an overhead camera above a unit I will be picking parts out of. I am trying to setup a robot generated grid in the space between the picking area and the camera, say a foot or so above the picking area. My issue is when I have the camera focused in on the part and I go to start teaching the target I can't because the target is blurry and unfocused. When I focus in on the target and then look at a part the part is blurry. My question is would I be okay to focus on the target to get through the target generation/calibration, and then adjust the focus back after it's completed to get a clear part image? Would adjusting focus after calibration ruin my cal-data?

Sounds like your depth of field is too shallow. Try decreasing the size of your aperture (increasing the F-stop).

hi ,
maybe a late reaction but i had a similar problem.
when you remove the lens from the camera there is a little piece of glas (light filter).
the chance is , that this is dirty .
clean it ,and it will be good as new.
