I've looked into this stuff a bit... isn't that the dream? Take a few 
photographs and then spit out a model? :)

Anyways, what I've seen done is a grid of laser light points is 
projected over the object. Using a grid of laser lights means that the 
points are always projected with known distances between them to aid in 
the calculations...

I can't find the page, but some guy was also trying to build his own 
homebrew digitizer. I think it was mentioned on slashdot if you'd like 
to search for it (I can't at the moment). Basically the object was 
rotated on a pedestal while a laser line was scanned vertically over it 
and used as a contour shape to be pulled from the captured images.

The thing I'd REALLY like to see (and wouldn't it help with this too?) 
is to be able to take a pair of stereo photographs and then have an 
algorithms spit out a depth of field image... They're doing it for the 
mars rovers, but...
