A stereoscopic three-dimensional optical metrology system and method
accurately measure the location of physical features on a test article in
a manner that is fast and robust to surface contour discontinuities.
Disclosed embodiments may image a test article from two or more
perspectives through a substantially transparent fiducial plate bearing a
fiducial marking; camera viewing angles and apparent relative distances
between a feature on a test article and one or more fiducials may enable
accurate calculation of feature position.
