I don't know where to ask this question but as I'm working with OpenCV I'll do it here.
I'm working with this camera: Blackfly 0.9 MP Color GigE PoE (Sony ICX692) with focal length 2.8-8 mm.
My question is how to set the focal to infinity so as I can see objects near the camera as well as far ones simultaneously without blurring. I don't know if that is possible! When I want to detect a chessboard for example, it works well when the board is on the focal plan but otherwise it appears little bit blurred so it's not detectable!
If it is not possible how you deal with that issue?
