Hi,
I am trying to use Vuforia together with HoloLens to recognize a target object I have previosly scanned using the Vuforia Object Scanner. The target is being recognized perfectly fine and this works pretty good. However, I can't position holograms on my target to augment it with virtual elements.
Even when I place a hologram at position (0,0,0) in local coordinates in my object target prefab, it does not appear at this position once running. There's always some offset. Also the position of my holograms depends on where I am actually standing when the target is recognized. This shouldn't be the case.
I know this is actually some pretty hard stuff to implement, but as I understand Vuforia should be able to take care of this. It's what it is made for. I have read this post: https://library.vuforia.com/articles/Solution/How-To-Align-Digital-Content-on-an-Object
But it doesn't really help unfortunately.
Thank you for any help in advance!
Greetings,
Dino

Have you closely followed the documentation? https://library.vuforia.com/articles/Training/Developing-Vuforia-Apps-for-HoloLens
Sounds like it could be related to #7 in section Building and executing a Vuforia app for HoloLens.

I've managed to fix my problem by applying the following position transformation in the TargetFound handler of my ITrackableEventHandler:

since I want to track my object only once and then disable vuforia tracking and keep it in place, I didn't run into this issue. But you are right, if you keep tracking it will always override the current placement.

I have now a solution, that works for me at the moment. It is not perfect, but I guess there will be a corrected version available by Vuforia sooner or later.

Did you ever find a solution
Did you ever find a solution to the offset problem? I'm having this issue now, even with the latest version of vuforia.
