EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Due the increasing requirements for an integrated system for dimensional measuring and defect detection, Danieli Automation has recently developed an innovative defect detection algorithm. Based on the data grabbed by the same high speed cameras also used for profile dimensional control, it builds a complete production quality assurance package. A high density and accurate 3D surface of the product is obtained by thousands per seconds complete profiles acquisition of the bar. The new adaptive algorithm creates a defective area map of the surface and dynamically follows its behaviour. False positive defect indications are dramatically reduced and detection sensitivity is continuously adjusted to best performance
