Abstract
There are provided a method and associated system for determining compliance of a part having teeth, crests or roots with a reference drawing. The method includes providing an image of the part; overlaying and aligning the reference drawing with the image of the part; analyzing the image of the part with the aligned overlay to extract a plurality of measurement points on the image of the part, each being associated with a corresponding crest or root of the teeth; and comparing the image of the part to the reference drawing in the crest or root regions to determine if the part is within a predetermined tolerance at each measurement point. The method is particularly suited for the inspection of parts having an uneven profile.
