I worked for one company that was able to automate stereophotogrammetry.
They placed sapphire beads (autoreflectors) at critical locations on the
part. One set of photos were taken with a high contrast film, so the
computer could scan them and identify the key locations. They were able
to obtain accuracies for the key points on the order of 0.001 in. radius.
