When
you love working with cameras and lights it’s easy to forget there
are other sensing technologies. Often, well let’s be honest,
usually, these are easier to use than vision. Yes, they lack the data
rich acquisition capabilities of a camera, but before grabbing that
Cognex Insight or Keyence IV sensor, think about what the application
really needs.
Now
it may be that you’ve forgotten just what a regular sensor can do.
In that case you might want to spend a few minutes looking over
“Sensor
basics: Types, functions and applications”
published on EDN.com September 12th,
2013.
It’s
quite a lengthy article but there are lots of embedded videos if
you’re not a reader. I found it excellent, and given that the
primary purpose of MachineVision4Users is to be a repository of
interesting stuff, I decided it warranted a post.
