Probably they need that for programming pick&place machines. But this 
would also require orientation, not just the center.

With refdeses it doesn't have to be precise, as long as it gets you into 
the vicinity. But the OCR would have to be able to handle bit map text 
and vector text. Another challenge are dense layouts where, for example, 
a part outline can butt up against the refdes on any given side. That 
throws OCR quite a curve.

I can give you an exact price, it's $495 plus shipping and sales tax:

GCPreView is really good, I've used it a lot.
