Difference in tracking quality on iOS

February 3, 2021 - 12:57pm #1

Hello!

We had made a Vuforia AR Project, on Unity Engine 2019.4.14.f1. The problem is - tracking and detection quality on Android and iOS builds differs. Some ImageTargets are recognized on Android build alright, but the same ones are completely ignored in the same project build for iOS. We make builds from the same Unity project, and had enabled Vuforia Fusion for better compatibility with native AR SDKs. Also, we forced enabled ARCore requirement in Vuforia settings, and ARKit requirement in Unity project settings.

So, why such drastic difference in quality with same project but different platforms? Thanks!

Hi @kingbaggot,

Using 2019.3 with 9.6 is not supported. Please use at least 2019.4 with 9.6.

@isoprophlex

Could you please run the coresample apps on the IOS device and let us know if the issue is reproducible?

And also confirm on which IOS device do you see this performence drop?

Thank you.

yes - I have noticed this too. Using Unity 2019.3 and Vuforia 9.6 and the tracking is significantly better on android. 

Also iphone 7 seems to work better than iphoneX  - not sure if this is a single vs multi-camera issue ?
