Tracking / orientation problems with Unity 5.6.1f1 and eyewear-unity-6-2-10 sample

June 13, 2017 - 8:50am #1

Hello,

We are trying to implement Vuforia tracking in an Hololens application (we already developed working Hololens and mobile Vuforia application, but not using both technologies).

Using the latest Unity 5.6.1f1 and the HoloLens sample project from vuforia-samples-eyewear-unity-6-2-10 we are having some serious tracking problems. The object is rotated in the wrong axis, and moving the target image causes the object to translate in the wrong directions. Looking up or down causes the object to follow the camera as well (this issue is not present when looking left or right).

We searched the forum and implemented some solutions to problems similar to our one, but without success:

- Match the print size of the physical target to the ImageTargetBehaviour's size (printout is 24 x 17 cm, size is 0.24 x 0.17)

- Make sure the orientation is set to LandscapeLeft (this is forced on when using HoloLens' VR support anyway).

Extended tracking is turned on. We tried building another project from scratch following the Getting Started guide for the HoloLens, but we end up seeing the same bugs.

Any advice?

Thank you Strasza.

 

Turning off MSAA has solved this.

Hello PranavBuradkar,

In version 5.6, Unity added a setting on the Camera called "Allow MSAA." This has been known to cause the issue you are seeing. You can deselect this checkbox on your camera to get around the issue.

We've reported this issue to Unity here if you want more information: https://fogbugz.unity3d.com/default.asp?899019_35ajcff7iq4voloc

Thanks

Hi , 

I am facing exactly the same issue with vuforia 6.2.10 and Unity 5.6.1f.

Have you found any solution to this issue?

 

-I am using a 30x42 cm Daredevil poster here, and as per the other posts in this forum, I have kept the exact width and height in ImageTargetBehaviour script.

Issue: https://youtu.be/QJPss6Rase4 (same video is attached as zip)

 

I am confused whether I have Implemented this incorrectly or there is something wrong with my HoloLens.

It will be really helpful If someone could provide me a working vuforia app for Hololens.

 

Thanks .
