Abstract: A method for inspecting geometrical shapes of objects to determine selected dimensions thereof based on data characterizing such objects obtained through stereoscopic photographs taken by a pair of cameras with fields of view intersecting to thereby provide a photographic event measurement volume that includes at least a portion of each of such objects being photographed. The method involves using previously specified procedures to check on the cameras performance consistency in photographing from different positions, preparing the object to be inspected including providing reference point targets thereon, scanning that object with the cameras from different camera pair positions, processing the resulting data to represent the scan basis geometrical shape of the object, and orient it to compare with the dimensional specifications therefor.

Abstract: A method of inspecting an internal feature of a gas turbine component includes removing a portion of the turbine component to expose the internal feature, treating the surfaces of the internal feature to provide the surfaces with a substantially uniform coloration, generating an electronic model of the internal feature, analyzing the electronic model generated with reference to a nominal electronic model, and providing an output based on the analysis of the electronic model generated.
