Stereoscopic three-dimensional metrology system and method

摘要: A stereoscopic three-dimensional optical metrology system (100) and method accurately measure the location of physical features (129) on a test article (120) in manner that is fast robust to surface contour discontinuities. Disclosed embodiments may image from two or more perspectives through substantially transparent fiducial plate (190) bearing marking (199); camera (111,112) viewing angles apparent relative distances between feature one fiducials (199) enable accurate calculation position.
