Machine vision systems for on line quality monitoring in industrial applications
AbstractThis paper is concerned with the topic of non-contact measurements for industrial applications. It presents the case of vision-based systems realized by the authors expressly for the measurement of geometric and/or chromatic parameters of rubber profiles for the automotive industry. After a brief description of the extrusion process, a stereo vision system for the on-line measurement of the dimensional characteristics of the profile transversal section is first described in all its main components and features, then two modules for the inspection of the finish of profile surfaces are presented.
