Image Tracking Misalignment

By sunnyviolet on Sat, 02/01/2020 - 19:18

Reproduction steps

  • Using Unity-Project-Template-2019.2..3f1 with the same Unity version
  • Imported Vuforia npm package scripts and updated to latest
  • Added image target database
  • Added imagetargetbehavior with a cube as the child
  • Pushed build to Magic Leap device
  • Image tracking appears to work but seems to be misaligned to the right by approximately 10%

Any advice on how to correct this misalignment?

 

Thanks,

Sunny

Hi,

I've tested the behavior and the alignment is good for me.

Could you please check the cube in the scene and confirm that it is not off there?

Thank you.

The child go is aligned to zero. I also have a mesh renderer on the parent that shows the original image target. Both the mesh renderer on the parent and cube child appear to be misaligned.

Thanks,

Hi,

Would it be possible to get the barebones project from your side to further test it internally?

If you don't feel comfortable sharing the project here, please pm me the link for dl.

Also could you please confirm the Lumin SDK version? 0.22 or 0.23

Thank you.

Hi,

I was able to *partially* reproduce the offset by looking at the digital copy of the image target, basically watching in on my screen.

However when I had the hard copy of the image target the offset was not visible.

I'm also experiencing misalignment with an image target with Unity 2019.2.20f1. Testing on my computer with a webcam everything works fine but on the Magic Leap the augmentation appears floating in front of the target about 10cm.

It is seem some time on unity project. I think Image data base has not worked properly it may issue there when we put there. So You can check there and view them.
