摘要: 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.
