Target Tracking is...Very Sensitive

March 25, 2013 - 2:20pm #1

Vuforia SDK Version: 2.0.31 -

Description with steps to reproduce: I'm using the target from AR Defender (http://www.ardefender.com/ardefender.pdf) just because it happened to have already been printed out here in the office.

Here's a screenshot when I run my setup:


As you can see, there's no model showing up, yet the target image is very clearly visible with no obstructions.

Another shot, managing to catch the displayed object:


And even when it DOES render the object, it jitters about as if the plugin can't quite figure out at what angle it should be rendering. Here's a video showing that behavior:


Note: the flickering video (mostly at the bottom) is likely due to the fact that the webcam I'm using is a piece of junk. It's supposed to stand up strait, and it separates from it's base, and I think that connection is failing. -

Development OS (Mac OS X, Windows, Linux): Windows 7 -

Mobile OS and Version: N/A - In Editor -

Mobile Device Manufacturer and Model name: N/A -

Do the Vuforia Sample Applications show the same behavior?: Y...yes? I tried the Image Targets demo with the teapots. Setting one of them to the target I have already, I was unable to get the teapot to appear entirely. So no idea if it jitters, just that it refused to show up entirely.

Yes, it is definitiely possible you have zero stars (by looking at the screenshots you sent), because the only relevant details are a few circles, and those are insufficient.

I didn't even see/know about the star feature when I created the target.

Looking at it now I still had trouble finding the stars.

Apparently zero.

Hi Draco18s,

the target that you are using seems to be a bit poor in features (i.e. the amount of details);

what star rating do you get from it (from the online Target Manager) ?
