ueye_cam calibration and parameters

edit

I'm trying to use ueye_cam package to control two uEye cameras: a UI122xSE-C and a UI223xSE-C. I've installed the IDS driver and I can use it to open both cameras. I'm trying to use rgb8.launch to control the UI122xSE camera first. However, I get the following warning whenever I run this launch with that camera:

How can I get the parameters? How can I calibrate the camera?

EDIT: I also have another question regarding the control of both cameras at the same time. Do I need just to modify rgb8.launch adding another ueye_cam_nodelet (like ueye_cam_nodelet2) with another camera_name (like camera2)?
