Experimental Machine Vision System for Training Students in Virtual Instrumentation Techniques

The aim of this paper is to present the main techniques in designing and building of a complex machine vision system in order to train electrical engineering students in using virtual instrumentation. The proposed test bench realizes an automatic adjustment of some electrical circuit parameters on a belt conveyer. The students can learn how to combine mechanics, electronics, electrical engineering, image acquisition and processing in order to solve the proposed application. After the system implementation the students are asked to present in which way they can modify or extend the system for industrial environment regarding the automatic adjustment of electric parameters or the calibration of different type of sensors (of distance, of proximity, etc) without the intervention of the human factor in the process.
