EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Here we present the HiNSPECT, a brand new machine based on shape-from-shadow technique, which aims at marking defective areas product surfaces with high accuracy within the zero-defects tolerance policy. Special lightning and innovative algorithms concur to highlight the defects with their pseudo-3D depth. Irregularities, such as scratch marks or inclusions, can be neatly seen in real-time without the need of reinspecting offline: small defects (less than 1 mm2) have been correctly located on the product surface with high-resolution images of hot/cold rolled products and displayed to the operator.
