title: Camera Calibration Intrinsic Matrix what do the values represent?
body: <p>So I did a camera calibration using the checkerboard and the matlab camera calibration toolbox. So the Intrinsic Matrix that I obtained for that particular session is as follows:</p>
  
  <p>Intrinsic Matrix: [349.3601,0,0;0,349.7267,0;258.0883,210.5905,1]</p>
  
  <p>I have been trying to search the meaning of those values in the matrix but has been unsuccessful so far.</p>
  
  <p>Can anyone help me?</p>
  
  <p>Thanks</p>
