Troubleshooting vision the MV4U way

It’s Friday afternoon and you’re about to leave the plant for a weekend of golf and beer (or whatever other activities float your boat,) when the phone grabs your attention. “The vision system on number three isn’t working and we need to get the order shipped by six tonight.”

Sound familiar? Well what do you do?

Over the next few days I’m going to take you through what I’ve found to be a reasonably structured, logical approach to getting to the source of real-world machine vision problems. I don’t claim to be the supreme authority on this, and indeed I’d welcome comments and tips, but I do hope to provide some sensible ideas, in a sensible sequence, that may help you still keep that tee time, and perhaps even avoid nasty glares from family members who expect you home promptly every night.

We’ll start by talking about the different failure modes, particularly that thorny question of “has something changed or has it always worked this badly?” before dealing with ways of resolving first a gradual performance drop-off and second, a complete “it’s rejecting everything” situation.

So stop by soon for Vision Troubleshooting #1
