摘要： A method for inspecting geometrical shapes of objects (11) to determine selected dimensions thereof based on data characterizing such objects obtained through stereoscopic photographs taken by a pair of cameras (14, 15)with fields of view intersecting to thereby provide a photographic event measurement volume that includes at least a portion of each of such objects (11) being photographed. The method involves using previously specified procedures to check on the cameras (14, 15) performance consistency in photographing from different positions, preparing the object (11) to be inspected including providing reference point targets thereon, scanning that object with the cameras (14, 15) from different camera pair positions, processing the resulting data to represent the scan basis geometrical shape of the object (11), and orient it to compare with the dimensional specifications therefor.
