One of their factories uses cardboard boxes to package their products. They are transported on several conveyors, which are sometimes difficult to reach. While being carried, some of the boxes often fall or end up in an invalid position (at an angle, upside down, skewed, etc.). If not detected in time, these mishaps sometimes force the company to shut down the production line – a procedure that can be costly.
To remedy the situation, the company installed a set of sensors along the conveyors to measure the height of the boxes and detect those that had fallen. This rudimentary equipment, however, failed to recognize boxes that were simply at an angle or skewed. This method thus proved to be very imprecise and regularly required human intervention. An employee was sometimes tasked with the constant inspection of all the factory’s surveillance cameras in order to confirm anomalies.
