Abstract

Quality control by artificial vision is getting more and more widespread within the industry. Indeed, in many cases, industrial applications require a control with high stability performance, satisfying high production rate. The purpose of this paper is to present a method to detect in real time defects located on the circumference of industrial parts that have a circular shape. Meanwhile, production steps can lead to an oval shape or to different sizes of parts. These two phenomena can lead to miss defects. Therefore a constant mask will not be able to detect these defects correctly. The control of the circularity of these parts can be achieved in two steps.
