What does Industrial Vision?

Modern imaging technology has many applications in research and development of industrial processes or surveillance & security applications.

Typically, a Vision system is PC-based, using a group of devices to receive, analyze and interpret the image of a real scene. The system makes judgments on the image using predefined criteria set by the user. This information can be used to automate go/no-go inspection decisions, assembly verification, part location and machine guidance, dimensional measurements, feedback control loops, awareness checks, access control and a host of other tasks.

It’s based on using a group of devices to receive, analyze and interpret the image of a real scene. The camera brings the digital or analogue image into the PC via a certain interface for further analysis/actions.

Examples of further analysis/actions are:

  • Security & Surveillance of objects or human beings (live stream or triggered)
  • Control: traffic, quality, awareness, etc ...
  • Object recognition
  • Identification
  • Completeness check
  • Measurement of objects
  • Surface/shape inspection
  • Comparison

The key benefits of imaging methods include:

  • Optical, non-contact measurement
  • Two-dimensional or three dimensional measurement
  • Visual, easy to use and understand
  • Based on reliable, cost efficient solid state technology

History of industrial vision?

From its roots in early research into artificial intelligence in the 1940s, vision is now an essential component of industrial processes as diverse as semiconductor manufacturing, pharmaceutical packing, film container printing and automobile manufacturing, etc.

1980’s: the first greyscale vision algorithms, industrial applications camera’s manufactured

1990’s: Massive growth of machine vision industry fuelled by availability of industrial systems. Smart cameras available using proprietary processing chips. Accelerated use of standard PC technology and Windows OS for industrial vision.

2000’s: Vision industry adopts FireWire (IEEE1394) digital camera technology. Market continues to expand rapidly.

In what kind of industries can “Vision” be used?

Modern imaging technology has many applications in research and development of industrial processes.

The potential applications for Industrial vision reach far beyond even those areas where human vision can be applied. These include conditions where light levels are too low or too bright for human vision, or where non-visible electromagnetic radiation such as X-rays or infrared is required. Industrial vision systems can be applied in manufacturing clean rooms and can survive environments too hazardous for humans.

Typical fields of industries where vision systems are or can be used:

CCTV – security & access control – border control – surveillance – videoconferencing – broadcast – traffic (monitoring/control) – medical – automotive (robot, pick and place) – textile (web inspection) – printing – food – vegetables & fruit (sorting/inspection) – solar industry - semiconductor (parts and/or PCB inspection) – military and space – aviation – steel – diamond – agriculture – ophthalmology – bio industry – glass – prototyping & reversed engineering – packaging – logistics – scanning(2D/3D) – non-destructive testing – laboratories – microscopy – education – and many more.

What are the advantages of “Vision”?

  • - higher efficiency
  • - high speed processing capabilities
  • - continuous operating (24 hours a day, seven days a week)
  • - high reliability
  • - vision systems ensures repeatable results

What’s the cost of a vision system?

The cost of a vision system depends on several - all even important - parameters:

  • - what has to be visualized (object) and what are the conditions (environment)
  • - complexity and scale of analysis
  • - accuracy
  • - System setup/configuration. A vision system can be split into:
    • - Hardware (e.g. optics, lighting, camera, cabling, frame grabber, PC, etc.)
    • - Software (SW license, development, HMI, etc.)
  • - Sub quantities
  • - Time schedule

In the last decade the price of a vision is almost been halved as products have matured, functionality has increased, suppliers have become smarter and the cost and complexity of systems have come down.

In 75% of the cases the cost of a Vision system is between EUR 5.000 and 30.000 EUR based on a PC-based system with one image sensor.
