Abstract
A high-speed, 3-D method and system for optically inspecting parts are provided. The system includes a part transfer subsystem including a transfer mechanism adapted to support a part at a loading station and transfer the supported part from the loading station to an inspection station at which the part has a predetermined position and orientation for inspection. The system also includes an illumination assembly to simultaneously illuminate an end surface of the part and a peripheral surface of the part. The system further includes a lens and detector assembly to form an optical image of the illuminated end surface and an optical image of the illuminated peripheral surface of the part and to detect the optical images. The system still further includes a processor to process the detected optical images to obtain an end view of the part and a 3-D panoramic view of the peripheral surface of the part.
