Vuforia moving even not tracked static scene 3d objects caused by autofocus and accelorometer

October 16, 2018 - 7:43am #1

Hi all,

in my scene if have an image marker that works fine. Besides this I have a 3D model that I want to show without tracking but with camera background, lets say static.

Now vuforia is manipulating the camera all of the time, especially field of view and some 'I guess' acceleromter information is causing my model to flicker on the ipad. On Mac it is all fine. When ever I move my hand in the range of the focus is moving back and force. Again - I am not tracking with object, image or anything else at this moment.

World Center Mode is Device.

How can I deactivate all of this features without stopping the full tracking in Unity which causes the camera to stop as well?

Thanks for your help.

Best Costa

Hello,

There was a time when ARKit did not support continuous autofocus, but that has been enabled in later versions of iOS. Vuforia has supported these camera functions since SDK 1.5 as long at the platform device supports it.

If ARKit is the issue and is not providing you with the focus modes you need to overcome this issue, you could consider configuring Vuforia Fusion to disable ARKit and use either Vuforia VIO or our legacy SLAM tracker:

https://library.vuforia.com/content/vuforia-library/en/articles/Training/vuforia-fusion-article.html (see "Fusion APIs" section)

These will enable the standard iOS camera, and thus enable additional focus mode options that may not be supported by ARKit.

Thanks,

Thanks for your reply.

I did not before because it was said on https://library.vuforia.com/articles/Solution/Working-with-the-Camera that this feature is not supported on iOS.

Now I gave it a try but unfortunately it did not work. Any other ideas?

Best, Costa

Hello,

Have you considered setting the camera focus mode to infinity?
