WARNING - BALD CONJECTURE AHEAD

I think that probably the most advanced means for doing this has been
developed for extracting depth from aerial stereopairs of terrain.  Is this
called aerial stereophotogrammetry or something like that?  Whatever it's
called, I imagine that it is or could be largely automated because many of
the geometric variables would be known or fairly tightly controlled.  I
would imagine that a human operator might have to match up a few homologous
points between the scanned images but that a sophisticated pattern
recognition program could do the rest.  Of course, this is a special
situation because only a very tiny part of the terrain visible in one
perspective would be obstructed in the other and there are no surfaces of
interest that are not visible in either view.

DISCLAIMER - I AM NOT AN AERIAL STEREOPHOTOGRAMMETRIST, NOR DO I PLAY ONE ON
TV.
