Image Tracking not working on HoloLens

October 24, 2017 - 3:39am #6

Hello!

I am using Unity 2017.2.0f3 and Vuforia 6.5 in order to track an ImageTarget and display a simple 3D model on top of it when detected. My problem is that the tracking seems not to work.

I created my own project using Vuforia stones image. I created my database and activated it, I tried different sizes of the image target. I set all configurations as stated in the various Vuforia guides. However, when I deploy the the app on the HoloLens, it does not display anything on top of my target. 

Also, I downloaded and deployed the ImageTarget sample from the Unity Store as it was, not changing any configuration. It turns out that the sample too does not work on the HoloLens.

To be honest, in one of my build (unfortunately, I do not remember the exact configuration of this one) the green cube was rendered when the image was being tracked. However, the cube was rendered in the wrong position: instead of being on top of the image and of the right size, it seemed it was rendered exactly in front of the user's nose and in a smaller scale.

Any idea on how to sort this problem out? Please, help!

I sorted out the problem! 

I noticed that in my XRSettings I had both Windoows Mixed Reality and Vuforia SDKs activated, as you can see from my previous images (OtheSettings.jpg). I got rid of Vuforia SDK and everything started to work properly (as in my new attached image XRSettings.jpg).

I am happy that everything works fine, but can I have an explanation of why it did not work before? Adding Vuforia SDK for HoloLens development messes things up this much?

Thank you!

Oh, I have just remembered that I followed this webpage to set up Unity configurations:

https://library.vuforia.com/articles/Training/Developing-Vuforia-Apps-for-HoloLens.html

Given my recent solution to the problem, I think this webpage is not correct.

That article is incorrect. I have raised the issue with the team responsible for it in order to get it corrected. You want to check the Vuforia AR support box, but leave the Vuforia VR SDK out of the list that you add Windows MR to. Sorry for the confusion this has caused you in getting the HoloLens working.

Thanks,
