Abstract:
1. A method for creating a two-dimensional geometric object model describing the geometry of an object for use in machine vision inspection, said method comprising: acquiring a pixel image representation of an object; generating a set of two-dimensional geometric part models of said object based on said pixel image representation, said two-dimensional geometric part models corresponding to different respective parts of said object, said two-dimensional geometric object model comprising said set of two-dimensional geometric part models; obtaining a test image containing the visual appearance of said object and a given known inspection measurement associated with the test image; performing test inspection on said test image using said two-dimensional geometric object model to produce a testing inspection measurement; and retaining said two-dimensional geometric object model when said given testing inspection measurement deviates from said given known inspection measurement by an amount lower than a predetermined threshold.
