title: Use EMGU to get "real world" coordinates of pixel values
body: <p>There are a number of calibration tutorials to calibrate camera images of chessboards in EMGU (OpenCV). They all end up calibrating and then undistorting an image for display. That's cool and all but I need to do machine vision where I am taking an image, identifying the location of a corner or blob or feature in the image and then translating the location of that feature in pixels into real world X, Y coordinates.</p>
  <p>Pixel -&gt; mm.</p>
  <p>Is this possible with EMGU? If so, how? I'd hate to spend a bunch of time learning EMGU and then not be able to do this crucial function.</p>
