CHAPTER 22 Automated Visual Inspection

22.1 Introduction

Over the past two decades, machine vision has consolidated its early promise and has become a vital component in the design of advanced manufacturing systems. On the one hand, it provides a means of maintaining control of quality during manufacture, and on the other, it is able to feed the assembly robot with the right sort of information to construct complex products from sets of basic components. Automated assembly helps to make flexible manufacture a reality, so that costs due to underuse of expensive production lines are virtually eliminated.

These two major applications of vision—automated visual inspection and automated assembly—have many commonalities and can on the whole be performed ...
