Why can't we use AugmentedFaces with Back camera? #54

Open SeyelentEco opened 5 years ago

SeyelentEco commented 5 years ago

I was excited about the release of AugmentedFaces but I don't understand the limitation around it only supporting the front camera in Unreal? What limitations exist with the back camera that the front camera solves?

I'm building from source with v1.7, so if there's a small change I can make for prototyping (even though not supported for production) , I'd be willing to do it.

ARCore doesn't support Augmented Faces for back camera yet. It's not just Unreal. Unfortunately you will have to wait until ARCore supports it. On Thu, Mar 7, 2019 at 9:54 PM Alex Petrescu notifications@github.com wrote:

Is this a feature coming soon or not on the roadmap? I would like faceboxes at least like ARKit.

I wish the same on Unity too. Why is the back camera not enabled? The option is present in Unity but when running the app error message "ARCore encountered a problem connecting. Please restart the app" appears. Restarting yields same result. I think it is to do with GPU and CPU camera configurations.

may 2020 i have tested with unreal change cam front to back and ..... always front camera

timneill40 commented 4 years ago

May 2020. Thank you! Will look at that.

If I am not mistaken: So far face tracking for Android in Unity : AR Core (and therefore AR Foundation) only working on front/selfie camera. Back/world camera not enabled yet.

greatAznur- did you have to do anything special to get Unreal to track from back/world cam? What device were you building to? Cheers

@timneill40

there is an option in the project to say which camera we choose but in any case it doesn't work for "augmented face project" .. uebacktofront

thanks - yes it seems that is the limitation most development environments (Unreal, Unity, etc) are faced with when using ARCore.
