Pharmaceutical Pill Inspector

Used by a pharmaceuticals manufacturer this system ensures the correct pills are present in the blister pack and in a good condition before sealing the packSpecial lighting is used to detect the color and shape of each pill in a blister back before sealing. The image to the right indicates various pill samples that had to be tested and some of the challenges that needed to be overcome by the automated vision inspection system that we designed.The colour vision system had to determine the colours of both translucent and opaque pills as well as their shape. This allows the positive identification of each pill as well as an alert for foreign objects, incorrect pills or damaged pills.
