Hologram from image target moves with headset

June 11, 2020 - 4:38am #1

Hello,

I'm having a weird issue: when I look at my image target, the recognition happens and my hologram appears. However it does not stick to the real image as intended but rotate everywhere when I move my head (hololens).

If I use the existing sample project from Vuforia, everything works fine. But if I create my own Unity project, with the exact same image target dataset, the above issue happens.

I tried to copy the exact same configuration options from the working sample project to my new project but without success.

I'm using Unity 2019.3.15, MRTK 2.3.0 (also tested with 2.4.0) and Vuforia 9.1.7.

Thanks for your help.

Try different MRTK configuration profiles. I found different behavior when altering these including the behavior you mention.

Hi,

As far as I know, not, we use the default settings.

Could you check your camera setup by going over our article: https://library.vuforia.com/articles/Solution/Working-with-the-HoloLens-sample-in-Unity

Thank you.

Yes it is a child of the image target. I did some more tryouts:

Do not work

1. Create new Unity project

2. Install Vuforia 9.1.7 from package manager

3. Install MRTK 2.3.0 from their github release page

4. Doesn't work...image target moves with my head

Do work

1. Create new Unity project

2. Install Vuforia 9.1.7 from package manager

3. Download the Vuforia Hololens 2 example from the asset store and import the MRTK from there (also version 2.3.0 it seems).

4. Work as intended

Was the MRTK modified to make it work with Vuforia?

Hi,

Very strange, could you please check and confirm that the augmentation is a child of the Image Target?

Thank you.
