IMAGE PROCESSING INSPECTION FOR LIGHT METAL PACKAGING

摘要

In this work a machine-vision system for inspection (VSI) is presented whose capabilities are able to detect seaming defects in metal cans for fishing food. Conventional method 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 on-line/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. Access to the Internet is provided through and ethernet LAN and a database is designed to collect and manage quality control results.
