In vision science we'd call it a "depth map"; the cartographers might have
another term for it, I don't know.

I'm afraid I haven't heard of anything like that in shareware; in fact, the
only programs I know of to do this sort of thing are highly experimental (&
not too accurate).  There probably are programs out there that
cartographers & photogrammetrists use, & I'm pretty sure there are people
on the list who know more about that than I do (anyone?).  I'd guess that
any such programs would require help from the operator in locating
corresponding points in the two images, that being the hardest part of the
problem from a computational point of view.

If you do find something, I'd be interested to hear about it.  Good luck!
