ABSTRACT:
A method and an apparatus for grouping individual products such as industrially baked products that travel past a visiometry station into lots for counting them. In a viewing zone of a conveyor belt, a laser triangulation visiometry system is used. The method and apparatus also uses a signal processor associated with the camera that deduces from the images acquired thereby at least one piece of information on the location of the products on the conveyor belt as well as height information thereon. This information is then used by the signal processor to automatically distinguish between the presence of a product and the presence of contaminating material (for example flour or chocolate particles) on the conveyor belt and to distinguish the presence of several partially or fully overlapping products from the presence of a single product on said conveyor belt. Preferably, two cameras are disposed symmetrically relative to a laser plane substantially perpendicular to the plane of the viewing zone.
