Abstract
A method and system are provided for inspecting manufactured parts such as cartridges and cartridge cases and sorting the inspected parts. The system includes an illumination assembly for evenly illuminating a plurality of annular, exterior side surfaces of a part when the part is located in a circumference vision station with rings of strobed radiation to generate corresponding reflected radiation signals. A plurality of imaging detectors in the form of CCD cameras are located at the vision station to generate a plurality of side images. The system further includes at least one side image processor for processing the side images of each part to identify parts having an unacceptable defect. The system further includes a mechanism for directing parts identified as having an unacceptable defect to a defective part area and directing parts not identified as having an unacceptable defect to an acceptable part area.
