Oh and the resolution of the IR camera is 1024x768, so use that when you're translating the pixel space coordinates into real world units. (Your IR data will be the brightness/largeness of the point as one unit, and the X and Y values as the other units.)

Hmm, I bet it be useful to have a library function that calculates that for you.
