Must be missing a step with object tracking video. Try it again have fun!

Hi, I have a similar problem. I loaded everything got it working, saved it. Went back to use it again, it wouldn't run. Reloaded objects etc., got it working again. I Just tried it, not working? No blue box.

Hi Bob,

I just played with my saved project some more and found the back lighting is very important, though I used the same lighting, object and program yesterday. The "blue box took a while (3-4 seconds) before it selected an object (my face), but finally came up. The second and third objects took less time but also had a delay. I saved it and loaded it again and it seems to be ok.

I have a simple speech recognition script running it, but I had duplicated Dj's example during earlier test.

There’s important things I say in the video - that I’m attempting to avoid repeating. If your object does not totally fill the Learning square, then the background will be part of the learned object.

The computer does not know depth. It has one eye (camera) and can’t know anything other than what is in the square. If there’s background, it’ll think that’s part of the object. Understand? It assumes everything in the square while learning IS the object.

So find objects with details that the computer can learn, not the entire object itself.

Also, lighting is important because when the color changes or brightness changes, the object looks different. The computer sees the object as a 2 dimensional thing, so rotating it will also make a difference.

Lastly, you MUST slowly move the object in different angles while learning in the square so it learns what the object looks like at different angles. When the computer sees the object as 2 dimensions, rotating the object makes it look like something entirely new.

Tutorials, such as the robot program episode in question, is a collection of instructions to learn how to do something. It takes us many many many hours to make one instructional video - and it therefore I recommend using it as a resource. It isn’t efficient for me to respond to assist what is already covered in tutorials - specially while expecting new features, new support, changes, etc... I can only do one thing at a time. So if my answer is vague and refers to the episode, it's because I'm swamped and don't have time.

Thanks Dj. The issue I have and I think Bob has also is the blue box fails to come on the screen. The position of my face is in the same location and the lighting is the same but the tracking box does not come on. I will try to come up with why it doesn't consistently work.

Thanks for the comments. I notice that the Camera control in the video is different than the one downloaded from ARC. Control in Video

Control from ARC

I don't know if that makes a difference.

Hi Bob,

Have you been able to get it to work yet?

I haven't had time today, tonight perhaps.
