Abstract:
A method in a system for using electronically acquired imagery from a one-dimensional camera to inspect an object for a wide variety of manufacturing defects, the method comprising the steps of:capturing, by the one-dimensional camera, a one-dimensional scan line of the electronically acquired imagery whereby each scan line includes an array of geometric elements; delivering the scan line to the system; sequencing the scan line, passing a horizontal line through the array of geometric elements, and reducing the scan line to a plurality of run-length integers whereby each run-length integer represents one run; systematically accounting for all possible interpretations of each run using a plurality of predefined rules to determine deviations from a set of acceptance norms for the array of geometric elements; and systematically testing each interpretation wherein invalid interpretations are ignored.
