Trackables not working

March 6, 2012 - 12:40pm #1

I've uploaded several images to make them trackable but so far I haven't had any success. I'm trying to track a bottle label but is not working. What could I be doing wrong? The width confuse me as to what exactly should I put there. I'm using the mm of the image that I measure in the printed copy. Please help :confused:

Good. Yes the docs need to be updated.

That's it! That's the missing step. Thanks a lot DavidBeard! I don't recall seeing that step in the documentation.

You still need to configure the Data Set Load Behaviour component on the ARCamera to load and activate the dataset. You'll see this panel in the Inspector when you click on the ARCamera in the Hierarchy.

If that doesn't work, try importing your datasets into the ImageTargets sample, and set up the sample to use your trackables.

Ok, here's what I do to setup my project step by step.

  1. I upload an image into my trackables and set the width to the width of the print copy in mm.
  2. Then I create a new project in Unity.
  3. To that project I import vuforia-android-1-5-10.unitypackage, a simple 3d model and the trackable I just created.
  4. I erase the default camera and place the AR camera.
  5. Then I add and ImageTarget and set its Dataset to the trackable I imported earlier.
  6. Lastly I add the model to ImageTarget and compile.

I don't know what I'm doing wrong. Am I missing a step? I'm a complete newbie in this. Thanks DavidBeard for your support. Also, I'm on Mac if that makes a difference.

Which version of the SDK are you using?

To confirm, are you sure that you're loading and activating the new datasets - that your environment isn't using another set of trackables?

The width of your label is fine, though I'd recommend an integer value.

Ok, this is getting weird. I'm not sure what I'm doing wrong here. I uploaded the default chips.jpg to my trackables using the same width of 247. I added it to the image target in Unity and still no tracking. :confused::confused:

The image have a rating of 4 stars. Is possible is the width. The chips trackable have a width of 247 but when I measure my print copy is 225 mm. So I'm confused about what to use as a width. The label is 98.38 mm, it may be that's too small?

Have you been able to create and import a trackable of the bottle label?

If so, what's the rating of the label - how many stars?

Go ahead and use the width of the printed label, the TMS will infer the height from the submitted image.
