Vision Systems

Vision systems use cameras to look at a surface and then compare the surface viewed to a “standard” or reference surface stored in the computer. They can be used to detect the presence or absence of an object, the presence of defects, or to make distance measurements.
Example of a vision system


  • Missing parts in an automated assembly line
  • Poor quality surfaces or components
  • Correct orientation of parts or labels
  • Ensure correct relative position
  • Color detection
  • Detecting incorrect product


  • Non-contact
  • Need to have sufficient light
  • Flexible (can be reprogrammed for a variety of applications)
  • Compact systems are now available
