Vuforia Image Target not working on HL

February 7, 2018 - 6:24am #1

Hello all,

 

I'm getting trouble to make working Image Target in Vuforia. My image target get recognized by the Webcam but not by the HL. 

I have also to say that I needed to do a "trick" to make HoloCamera and ARCamera working together. I was having the problem that Hololens was having the vision of ARCamera but was moving with the HololensCamera (see in my scene that i'll link). So i had to synchronize postion, rotation and transformation matrix of the two camera with a little small script.

 

I need also to say that the scaling of the Image target is like in the reality (5.5cm) but that should not be a scale problem because when i'm using the webcam like I said that's working.

 

Any idea on that?

 

Here is the link to my unity project, feel free to download and look what i've done wrong :D

Problem is fixed!

 

Don't start the application from Unity, build and install it on the Hololens, that was my problem

Vuforia Image Target not working on HL

Hello !

 

I'm using the unity version: 2017.3.0 and I don't really know how to know that.

I tried to use the unity vuforia hololens sample one and when I launch it on the hololens via the holographic emulation windows of Unity the HL doesn't recognize the image target of the sample (I printed them on paper).

On your sample project there is an other problem that i'm having, when I move with the Hololens the AR camera doesn't move at all and the head rotation aren't tracked too.

Have I done something wrong ?

Hello Upd4ting,

Which version of Unity and Vuforia are you using? Have you looked at our HoloLens sample on the Unity Asset store?

Thanks,

Vuforia Support
