Correct lighting is the most crucial element for successful machine vision applications. To successfully apply machine vision, basic lighting concepts and lighting techniques for industrial applications should be understood.
Machine vision systems and smart cameras are capable of precision measurements. Precision measurements are needed for inspection and quality control purposes. To facilitate exact measurement, the vision system must identify edges and other part features by maximizing contrast through various lights and lighting techniques. With many machine vision applications, solving lighting issues is tantamount to solving the application itself.
