Camera Operation and Calibration issue

Attempting to calibrate camera. We’ve ran rosdep and rosmake.
rostopic does not show cameras. What should we do now?
I suppose the question is, how exactly are we supposed to calibrate the camera?

Hello Josh,

Could you provide some more details on your use case?
Which device are you using, is it ROSbot or CORE2-ROS?
What camera is attached to your device?
How are you starting the camera driver?
Do you get any errors or warnings?

Regards,
Łukasz
