Abstract :
In this study, we have presented the prototype of optical lens eccentric error inspection system based on image processing algorithms. The traditional inspection by using the transmission or reflection measurements is limited to the geometry and size of the lens. In this study, an image based inspection system has developed target on fast, accurate and low-cost to meet the need for lens eccentric error inspection.
