Machine vision inspections using visual cameras can occasionally cause recognition problems if the product and background have too little color contrast. In such cases, thermal imaging cameras can be a practical solution – especially if the product has a different temperature than the transport medium.
In many cases such temperature differences are caused by the production process. Injection molding applications are ideal for this, for example, because the produced parts come out of the machine here at a relatively high temperature.
A few years ago, at the German Rubber Conference DKT in Nuremberg, two Austrian companies presented a possible solution in this area. [Read more…] about Machine Vision: Pick and place with FLIR thermal imaging cameras
