| Technique - The use of colour in monochrome vision |
|
|
Creating consistent contrast is the goal when
selecting
lighting for a machine vision application, and because
no two materials respond to the same colour the same
way, it is important to take time to consider the colour
before purchasing a light.
The most common LED colour used for automated
inspections is red, although red is not the answer for
every lighting problem. So, how do you choose the LED
colour that will provide the best contrast for your
application?
The rule is: "Like colours
lighten, opposite
colours
darken". For
instance, a yellow object under blue light
appears darker, while a blue object under blue light
appears lighter.
Light colour matched to the part colour can
highlight or eliminate specific characteristics, depending
on the needs of the inspection. In an OCR application,
green lettering on aluminium will appear darker to the
CCD if a red light is used; if the inspection is for
aluminium quality, that same blue green will virtually
disappear under green light, allowing the vision system
to look for surface flaws or defects.
