Modelling vision inspection system for fuzzy logic

A machine-vision system for inspection (VSI) is presented whose capabilities are able to detect seaming defects in metal cans for fishing food. Conventional methods for quality inspection of seaming for cans, and their main dimensional features, are first shown. Then, the structure and algorithms for VSI are proposed for this application. This VSI is currently mounted over a conveyor belt for online/in-process inspection of metal cans, in order to assure their conformance to the given seaming requirements by detecting malfunctions of closing machines and logistic process failures.
