A machine vision system for measuring the dimension of A disc and surface roughness evaluation

Abstract:
This project proposes a machine vision system for inspecting the dimension of discs. The system consists of a personal computer with a frame grabber, a black and white progressive scan CCD camera, and a mechanical device with a stepper motor controlled by a special controller. The proposed machine vision system allows fast, accurate, reproducible, and robust 100% inspection of discs and as such may be a valuable tool for ensuring high-end-product quality. The machine vision system is, thus able to keep up with the disc production process, inspect every disc and reject defective ones. Also the surface roughness of the object is found by using intensity histograms.
