HOLOLENS Vuforia sample with Unity.

Target Platforms XR
1

Good Afternoon.

I have loaded the example hololens scene, when I try it with my Hololens, I have a problem when I want to track the teapot. When I track the teapot, his position not is correct. It have certain offset of the target, if I approach the target, the teapot approaches the target, and vice versa.

ME --------- target --------- teapot
ME – target – teapot

All GameObjects are in (0,0,0) position.

Any help?
I hope I explained correctly, thank you in advance.

What version of Unity are using?

This seems to be a Vuforia issue, so you may want to try asking on their forums:
https://developer.vuforia.com/forum

You can also try the steps below:

  1. Launch the Hololens Scene
  2. Look at the target image until the Teapot appears
  3. Remove the target image
  4. Walk around and see if the target moves

Please let me know what your result is. If the teapot stops moving without the image target, I suspect the Vuforia image recognition keeps getting retriggered as the position of the camera changes, causing the teapot to be redrawn in a new location.

I’m using Unity HoloLens 5.4.0f3-HTP (64-bit)

I have not done it yet, when I do I will write it. Also I will ask in the forum of vuforia, to see that they respond to me.
Thank you!

I have the same problem here, when I compile the version to test with the hololens camera i can find the object but the object targeting set another place (X, Y, Z) of the hologram to represent. I try to code some axis manually when target is found (targetFound() method on vuforia) but… doesn’t works fine for me.

If you create a post on vuforia forums, please let us know to follow the issue. I will create one too.

Hello again, Gomeslaw. I suggest you upgrade to a newer build of Unity, such as the latest 5.5 release. That build you are using is no longer supported and we have made many great improvements to the Hololens experience in newer builds. Vuforia functions much better as well when paired with Unity 5.5 or 5.6 beta.

Hello Masakure. As I mentioned to gomeslaw in the previous post, please make sure you are running at least Unity version 5.5

I need a little bit more information to be able to help you:

Specifically, which of the Vuforia demos are you running?
Did you make any changes to the scenes?
Did you set the Virtual Reality Supported setting in Player Settings to Hololens?

I have the same problem. Holograms stays under/behind the target images.
Recognized correctly, but not on top of the targets as I placed them un unity editor.

Does anybody found a solution?

Unity 5.6 and Vuforia has some issues. Read this for solutions: Getting Started | Vuforia Library

At least it stops the flipping. Objects are under the targets though…

Is it possible to configure Vuforia to Use Hololens camera while in Editor’s debug mode using remoting?
