Abstract: A system and method for counting objects or parts on a continuously moving conveyor, or other elongated surface, provides a camera and associated machine vision system that acquire/capture and analyze multiple, successive fields of view taken within an area of interest defined by the system. Each of the fields of view includes flanking right and left overlap zones with respect to adjacent fields of view. The overlap zones are defined to be at least as wide as the maximum width of a part being counted. The captured fields of view are stored within the system and analyzed in succession based upon a set of rules. These rules determine whether or not a particular part within the subject field of view is to be counted. More specifically, the rules are applied within the overlap zones for each field of view to determine whether or not to count the part.
