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.

Do i need to make an xml file for that? the example in the tutorial said that i have to make an xml file as the configuration file, or will i just modify the code a little bit?

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.
