Paper Abstract

For many years, manufacturers have been both managing and assuring the quality of their products. Among the many concepts used at present, artificial vision is chosen to control conformity during the production process. The real time control of 3D reflective objects is our concern in this research work. In the recent past, work has been done showing the capability of a vision system for detecting and measuring defects on non-moving 3D reflective manufactured products. For this new industrial application, defects we are trying to detect are dusts included under the metallic layer of products. The defect detection is still based on the use of a specific lighting system composed of light stripes. By examining the reflection of light from object, we are able to detect defects between two consecutive white stripes. The optimal detection has been obtained by adjusting the characteristics of the lighting system while taking into account the 3D geometry of the defects to be detected. The machine vision system performs the control of one cylindrical product within one second.
