MRTK 2.2 ; Vuforia and HoloLens 2

February 26, 2020 - 6:44am #1

Hallo Evreyone ! 

I m trying to develop a project that on Hololens 2 . I use Unity 2018.12f1 , Mixed Reality Toolkit 2.2  . Accually my project is composed from multiple Scene so i uses the Mixed Reality Tool Kit configuration and enabled the Scene System and Scene Transitions go from one Scene to another . It works fine . The problem is  : i need to reconigze a QR code so i used Image Target in the Scene Hauptseite under The Image Target there are some Objects that shoud be shown up when the image recognized . What i did , i added Vuforia Behavoir and Error Handler script like when you add AR camera so . 

1) When i play my project in Game Mode it works but the image will not recognized because it s another Scene and When i put it in The Hauptscene Manger where the camera it works fine 

2) The second Issue , when i bullt my project and run it on Hololens ,this cause the App to stop i don't why , but i m pretty sure that evrey time i add Vuforia Behavoir it stop to run 

 

Thx in advance 

Ps :Sorry if My English was too bad .

Hi,

I want to confirm that we use MRTK v2.2 in the Vuforia Hololens 1+2 samples.

I've asked for more details in your initial post.

Thank you.

I am not the original poster of this issue, however I'd like to point out an error in the response from Vuforia Engine Support:

Hi,

We demo the use of MRTK + Vuforia + Hololens 2 in our samples https://assetstore.unity.com/packages/templates/packs/vuforia-hololens-1-2-sample-101553

My advise would be to go over our samples and see how we implemented them.

We have examined the sample project available at the above link and compared it to versions of the MRTK v2 released by Microsoft for use with the HoloLens 2, and found that the sample does NOT use the MRTK at all. Instead it uses a rudimentary version of the HoloToolKit from around late 2017/early 2018, and is entirely unsuitable for Hololens 2 development.

I have made another, much more detailed post regarding our experiences of trying to port a non-Vuforia HoloLens (1) project into Hololens 2 and add Vuforia support, which describes the issues we encountered while trying to get Vuforia working with the MRTK v2.x. This post is available at the following link:

OP seems to have deleted their account, but hopefully this will help anyone else who ends up here!

In regards to your first question/issue it is not clear to me what the issue is, is the camera not working?

Could you please run the app with Debugger on in VS? or any log dump would be helpful to understand the crash.

Thank you.
