Machine vision systems
use computers and digital imaging technology to perform visual tasks such as
inspection, measurement, quality assurance and control of visual quality
parameters. Traditionally, these tasks were performed by trained
persons. However, human inspectors suffer fatigue and their assessments
are variable depending upon environmental factors. Machine vision systems
provide consistent performance and objective standards.
The design of a machine vision solution is highly dependent upon the task to be
performed. The choice of camera (resolution, line scan or area scan,
colour or monochrome), the selection and arrangement of lighting and the
construction of the systems are often just as important factors as the choice
of image processing and computer vision algorithms. All these factors are
best decided by a consultant working closely with the industry that will be
using the system.
