In this demonstration, a Checker® vision sensor performs high-speed label inspections on deodorant sticks. First, the vision sensor detects the deodorant stick, then it checks for the presence of two labels. As the speed increases the vision sensor continues to deliver 100% accuracy, even at rates of 1,500 parts per minute. http://www.cognex.com/industrial-sensor-checker.aspx?cm_campid=CBE3862F-9518-E211-AE9B-5EF3FCDAF1B7
