ABSTRACT:
A line-up vision system for testing the alignment of a workpiece in a holder of an automated machining apparatus. A light source illuminates one portion of the workpiece and keeps another portion of the workpiece dark. A light colored backdrop provides a sharp edge along the dark portion of the workpiece for a camera directed toward the backdrop. As the workpiece is rotated slowly the camera observes any movement of the sharp edge to determine if the workpiece is properly positioned in the holder of the machining apparatus. If the workpiece is properly positioned the camera provides signals which cause the apparatus to proceed with machining operations on the workpiece.
