Abstract:
A method of measuring a parameter of goods being fabricated in a manufacturing operation, the method comprising:(a) establishing a target parameter to be measured on respective units of the goods, and acceptable conditions of the target parameter;(b) capturing a full digitized visual image of a unit of the goods being fabricated, the digitized visual image representing pixels and pixel combinations in the visual image;(c) in the captured full digitized visual image, analyzing the digital pixel combination representations in at least first and second areas of the image, which respective areas of the image are specified to indicate, collectively and in combination, a common acceptable condition of the target parameter, and thereby generating respective first and second replicate determination signals representative of the target parameter;(d) analyzing the determination signals in combination, for conformity of the established target parameter to the established acceptable conditions utilizing respective analysis methods; and(e) processing the determination signals such that if a given one of the determination signals is concluded to be inappropriate, modifying the signal combination to thereby compensate for the inappropriate signal.
