The use of metal sandwich panels is widespread in the construction industry. These metal panels are visually inspected in line before arriving at the construction site. Defects are often only spotted up to 72h after leaving the plant and once they have already been put to use. Therefore the parts need to be unmounted as handling costs are claimed to the manufacturer as liability. In addition to this, a large percentage of the defective panels spotted on site have to be turned into scrap. Relimetrics uses computer vision to digitize inspection in line and trains algorithms to detect defects early. This allows manufacturers to avoid future handling costs and helps establish full traceability of quality.
