    Patent number: 9568438
    Abstract: The single-camera angled conveyance inspection method and apparatus includes upwardly and downwardly angled conveyance mechanisms positioned within an instantaneous field of view of a digital line scan camera. As a rotating object is moved over the conveyances by a helical guide, the camera obtains images of the object and communicates the images to a processor.
