ARCore 1.4 Auto Focus

By vridge on Mon, 09/10/2018 - 04:54

We are using Vuforia 7.2.24 on Unity 2018.2.7f1 for Android, and ARCore enabled using core-1.4.0.aar. Ground surface detection works great, but Image Targets and Multi-target/cuboids does not work properly because of the fixed focus that is set by default in ARCore.

However, we are using ARCore 1.4 aar file, and that version already includes the option to set Camera Focus to Fixed or Auto (fixed by default). Could you please enable/expose the option to set ARCore Camera Focus setting from Vuforia (or just set it to auto by default)?

Maybe when setting CameraDevice.Instance.SetFocusMode to FOCUS_MODE_CONTINUOUSAUTO could set ARCore Focus to Auto as well if arcore 1.4+ is detected (RuntimePlatform.Android and FusionProviderType.PLATFORM_SENSOR_FUSION)?.

We really need to be able to set it to Auto to make it work properly with vuforia's Image Targets and Multi-target/Cuboids, that is required to combine the powerful ARCore ground plane detection + the awesome vuforia target tracking, actually is the only missing part to accomplish that.

Thanks!

In Java, should be just:

Config session_config = session.getConfig();
session_config.setFocusMode(Config.FocusMode.AUTO);
session.configure(session_config);

Could you please expose/add this feature?

Thanks!

Hello vridge,

These feature of ARCore 1.4 will be available within Vuforia 7.5 which should be available within the next month. It was not available within the current 7.2 release as 7.2 was feature complete before we had access to ARCore 1.4.

Excellent, great news, thank you very much!
Could we have early access (alpha/beta) to that version so we can try it in advance on our side?
Thanks!

Would it be possible to consider adding a bug fix for this issue on the upcoming version as well?
