Disable ARKit to improve camera FOV

Hi,

we have multiple apps with multiple Unity (2017-2019) and Vuforia (6-8) versions, tested on various Android and Apple devices.

Starting from Vuforia 7 you introduced taking the advantages of ARKIT and ARCore to detect ground plane and so on. As I understood so far, if ARKit support is detected, the camera settings were set to ARKits preferred settings which ends up in cropped camera views on some devices.

 

Here are a few examples of this behavior:

1. iPad 4, no ARKit support, apps build with Vuforia >=6 have the same FOV as the native camera app.

2. iPad Air 2, no ARKit support, apps build with Vuforia >=6 have the same FOV as the native camera app.

3. iPad 2017 (5th Gen), ARKit support, apps build with Vuforia =6 have the same FOV as the native camera app, apps build with Vuforia >= 7 are zoomed in / cropped.

4. iPad 2018 (6th Gen), ARKit support, apps build with Vuforia =6 have the same FOV as the native camera app, apps build with Vuforia >= 7 are zoomed in / cropped.

 

My questions are:

Can you agree with these facts?

Is there any way to disable ARKit support to get the old FOV back or configure something else to get rid of the cropped camera view?

 

I appreciate any help,

Carsten

Hello,

thank you for your fast response. I tried to switch the fusion provider to VUFORIA_SENSOR_FUSION and VUFORIA_VISION_ONLY and added a TextField to display the current selected fusion provider. The provider ist set but unfortunately without changing the cameras FOV.

Hello,

Admittedly, this is the first report of this issue that I recall receiving. So, the effect is unexpected and thus there is no workaround that I'm aware of.

Because I haven't found a solution so far I added two screenshots made with the same distance between table and device with our iPad Air 2 (good) and iPad 2018 (bad) running the same app with same settings with some "beautiful" markers on my table:

 

We have the exact same issue here.. Working and presenting this ARKit FOV to clients looking for simple image-tracking capabilities is NOT a viable option. We rather implement AR ourselves than sticking to this FOV.

Please Vuforia would find a solution? Perhaps an option supporting old-style AR without ARKit would be good already.

I did another quick check to compare all possible combinations of the fusion provider and camera mode settings:

Is there anyway to remove it totally?

When i submit my app to appstore using the new sdk the reviewer keep insist that i'm using arkit and demand more functionality.

But i previously able to submit simmilar app using sdk 6.
