What is Machine Vision Technology?

Vision inspection has become a key technology in the quality control and product inspection during the automated manufacturing process. The ongoing demand for greater quality has determined a need for accurate and efficient inspection, far beyond what the human eye could provide.   The use of cameras are strategically placed over a production line to visually record a process, inspect, read or direct products without intervention. Using specialised software, information is then recorded and transmitted back to the end user for analysis. A typical machine vision system will be part of an automated production process consisting of the following components: 
  • One or more digital cameras (monochrome or colour) with suitable optics for acquiring images, such as lenses to focus the desired field of view onto the image sensor and suitable, often very specialised, light sources
  • A synchronizing sensor for part detection (often an optical or magnetic sensor) to trigger image acquisition and processing some form of actuators to sort, route or reject defective parts 
  • A computer program to process images, detect, measure, compare data in order to confirm a quality criteria has been met or to provide type verification for output of the results to another control system.
  • Input/Output hardware (such as digital I/O) or communication links such as Industrial Ethernet or ProfiBUS to report results and to automatically reject components
