There are two ways to calibrate cameras. The example uses the pattern matching method and I think you are just asking how to open the camera and get an image. You will also have to print the patterns on a piece of paper for the camera to see.
The one example located in opencv\sources\samples\cpp\tutorial_code\calib3d\camera_calibration has a camera input mode. If you look at line 112 where if (inputType == CAMERA) inputCapture.open(cameraID);
You will see where it opens the camera using HighGui
The biggest issue I had with the example is that it ONLY adjusts for spherical distortion. You have to do several more steps to measure the rotation and shear and scale if needed.
that's up to you. I just commented out the code for the XML file and set the settings the way I wanted to test and then I started on my own code.
