Abstract
A method and system for inspecting unidentified mixed parts to identify the parts are provided. The system includes an inspection station which includes a vision-based robotic subsystem including a robot configured to pick up a self-supporting part and place the part on a fixtureless rotary stage so that a part axis of the part is substantially centered and aligned with a measurement axis of the inspection station during part rotation. A second subsystem optically measures a profile and features of the self-supporting part during part rotation. A processor is operable to compare the profile and the features of the part to be identified with the profile and corresponding features of stored templates to identify a template which matches the profile and features of the part to be identified and to generate and transmit an identification signal representing a part identification code for the part associated with a matched template.
