Resumo

Here we present the HiNSPECT, a brand new machine based on shape-from-shadow technique, which aims at detecting defective areas on flat and round surfaces with high accuracy within the zero-defects tolerance policy. Special lightning and innovative algorithms concur to highlight the defects on the base of their 3D content. Irregularities, such as bumps or holes, can be neatly seen in real-time without the need of reinspecting offline: small defects have been correctly located on high-resolution images of hot/cold materials and promptly displayed to the operator.
