Machine vision has been defined by the Machine Vision Association of the Society of Manufacturing Engineers and the Automated Imaging Association as "the use of devices for optical, noncontact sensing to automatically receive and interpret an image of a real scene to obtain information and/or control machines or processes."
There are specific differences between image analysis, image processing, and machine vision. Image analysis generally refers to equipment that makes quantitative assessments of patterns associated with biological and metallurgical phenomena, whereas image processing generally refers to equipment designed to process and enhance images for ultimate human interpretation.
The instruments used to interpret meteorological and earth resources data are examples. Machine vision involves automatic image interpretation for the purposes of:
- process control
- quality control
- machine control
- robot control
- other functions like traffic control, and crowd and security surveillance
Machine vision is an automated technology in which images are captured and transferred to a computer, and then processed to perform an inspection task and report the results. Machine vision systems have become more powerful while becoming much easier to use. Recent advances in machine vision technology, especially related to smart cameras, have opened the doors to machine vision use for a wider variety of industrial and nonindustrial applications.
From a mere 6% to 8% of the total market for machine vision systems about a decade ago, their share of the nonindustrial segment went to about 20% in 2006 and is expected to be around 35% to 37% in 2012. This is a very impressive increase. The principal objective of this report is to study the impact of such an increase on the use of machine vision systems in the nonindustrial sector, how it affects the technologies involved and how the machine vision industry is tackling this challenge.
Significantly, machine vision involves automatic image interpretation for the purpose of control (as mentioned above: process control, quality control, machine control, and robot control). Distinctions are made between image analysis, image processing, and machine vision. Image analysis generally refers to equipment that makes quantitative assessments of patterns associated with biological and metallurgical phenomena. Image processing generally refers to equipment designed to process and enhance images for ultimate human interpretation. Instruments used to interpret meteorological and earth resources data are examples
