Vision Tracking Grey Totes

[btcshields6]

Hey everybody. I posted a few days ago in the general programming section about the 2015 Vision Tracking example. I have yet to get any response, but I have managed to learn a little since then, so I thought I'd sort of restate my question(s).

My goal is to be able to track a grey tote. I'd like to track from the short side (not that that makes a huge difference, as the grey totes don't have tape on the sides). I've looked at the 2015 Vision Example, which includes a VI for shape and color processing. However, I haven't had success with picking up a grey tote.

While I was looking into this problem, I checked out NI Vision Assistant, but I can't seem to find a way to consistently lock onto a tote. I'd like to use the Vision data for centering, so I can't just match the color, which wouldn't consistently hit the same point on a grey tote.

So I suppose I have two questions.

1) How can I get the example to register the grey tote?

and

2) If I can't get the example to run, how can I track a grey tote for centering?

Thanks,

Benjamin Shields
