title: Camera Calibration: Can Wrong Dimension Give Correct Distortion?
body: <p>When calibration a camera, one must provide a set of 'world points' (points on the real grid with real world units), and a corresponding set of 'image points'.</p>
  
  <p>My question is: if I were to factor a 'world points' by an arbitrary factor (in other words, give a wrong dimension of the real world units), would I still get a correct values of distortion and principle point (ignoring the obvious wrong values of focal length)?</p>
  
  <p>In other words: will the distortion coefficients and principle I yield stay numerically the same, regardless of the world points scale?</p>
