Image target content unstable!

SDK 9.8
August 21, 2021 - 1:55am #1

Unity version: 2019.4.25f1
Vuforia version: 9.8.5

Hi there, I'm facing an issue where the image target is tracked and the 3d model (as a content) is shown but the 3d model is unstable.

This is the second version of our app with more than 100 image targets. In our first version with around 30 targets, we did not face this problem. Is this problem because we have too many image targets in one scene? or is the problem something else?

I have attached ZIP of videos showing the problem.

Hope to solve it soon with the help!

Thanks,
Dan.

Great to hear! This is a general issue and relates to the width you set your image targets. 

The width (in meters) should be relative to the size / width of your physical image. If your image is 30 centimeters in the physical space, you should state 0.3 in the width property (see attached image).

This might make your scene in Unity very small. In this case you should check out the virtual scene scale factor to be able to work more easily in the editor.

Let me know if changing the width improves the tracking combined with the device tracker.

Hi Patrick Scheper, sorry for late response as I was testing a lot of scenarios and yes you are right disabling device tracker solves the issue!

I need the device tracker on because we are using extended tracking. How to solve it without disabling tracker?



Thanks,

Dan.

Hey there,

 

Sorry that you feel it's taking forever, but I asked below if you could disable the device tracker and check if the tracking is more stable?

This is taking forever!



Can I open a ticket or something? I need to resolve it within a few days.

Hey Dan,

 

Would you be able to test the tracking without the device tracker enabled (see attachment)?

Does that make the tracking more stable?

Hello @dhanrajsinh,

I tried to open the attached file below to review, but it's failing for me. I've opened a ticket with dev-ops to investigate further.

In the meantime, can you post the video to a file sharing service like Google Drive or YouTube? I'd like to review the behavior to see if it provides any insights.

Thanks,

Hi Patrick Scheper, thank you for your response!



The issue is on all iOS devices. 

All image targets have good ratings (4/5).

Issue is appearing on all image targets.



Do you need more details?



Thanks,

Dan.

Hey there,

 

Which device are you currently testing on? Also, how many stars do the image targets have? Is this issue appearing on every image target, or some of them?
