ABSTRACT:
An apparatus for inspecting sheet metal parts includes a computer for comparing a master representation to an inspected part. A part is scanned by passing the part in front of a computer vision system and an approximation of the part is thereby generated for comparison with the stored representation of a master part. The comparison includes checking for distance tolerances and proper feature placement of the scanned part and an inspection report for each inspected part is generated, indicating part acceptance status. Part tolerances may be varied for different parts and a library of parts may be consulted to automatically select an appropriate master part for comparison purposes.
