Abstract
A method and system for verifying the presence of a lens in a transparent package. The method comprises the steps of moving the package into an inspection position, and conducting a light beam through the package and onto an image plane to form an image of the package on the image plane. The method further comprises the steps of generating a set of signals representing the image on the image plane, and analyzing those signals to determine whether a lens is present in the package. This analyzing step, in turn, includes the steps of searching the package image for images of discrete objects; and for each object image found in the package image, identifying values for a plurality of parameters, and analyzing those identified values according to a predetermined procedure to identify the object as a lens or as not a lens. A lens present signal is generated if one object image found in the package image is identified as a lens; and a lens missing signal is generated if no object images are found in the package image, or if all object images found in the package image are identified as not lenses.
