Abstract
A system for inspecting cylinders according to various aspects of the present invention generally includes a roller assembly comprising a plurality of rollers configured to hold the cylinder. A light source illuminates the cylinder and a camera produces an image of at least a portion of the cylinder as the roller assembly rotates the cylinder about its longitudinal axis. A computer system is configured to control the roller assembly, light source, and camera and analyze the image to identify a defect associated with the cylinder.
