Food and packaging inspection

Food and packaging inspection, which includes detecting, measuring, or counting bottles, cans, boxes, labels, foods, tablets, etc., presents a different challenge than electronic or semiconductor inspection. Finding dead pixels in flat-screen TVS is important, but making sure that labels on prescription drugs are accurate and clear, and that food containers aren't contaminated before they're filled and properly sealed after they're filled, is crucial. Industrial machine vision plays an important role in the quality control of many foods and drugs. Color imaging is not necessary for many industrial applications, but is very important in food inspection and is often used to determine whether it is ripe or done.






Food, drug and packaging testing also presents other challenges: some foods, machines or containers cannot tolerate exposure to bright light or high temperatures. This makes low lighting image quality very important.
