You might be better off using a ordinary forwards facing camera, and match-mover software (like boujou) that the use in movie effects to work out the camera movement and add virtual elements. There seems to be a free match-mover (camera tracker) package at http://digilab.uni-hannover.de/docs/manual.html that's probably worth a try.
