How to map an image from pixel coordinates to real world coordinates

Can someone help me with the following problem? My goal is to transform an image of a target (e.g. chessboard) with known dimensions and than transform that image in a way, that the chessboard pattern is horizontally and vertically aligned with the pixel coordinate system. I found a lot of nice tools to dewarp or register images (the camera calibration toolbox of Jean-Yves Bouguet for example) but so far I couldn't find anything of how to transform the image so that the x- and y-pixels correspond to real-world length scales. Can someone give me a hint where I can find a solution to that problem?

If you use the Computer Vision System Toolbox to calibrate your camera , then you can follow the instructions here.
