AR app with rear camera face anchor

Trying to develop an app with face tracking using the rear camera of an iPad

or iPhone. All documentation available seems to refer only to front camera cases. Am I trying the impossible here?

While a dual camera back can capture depth, the rear cameras are not TrueDepth so no Face ID nor related support.


Apple Developer Documentation


Face detection runs a parallel scan using an IR point scan. It’s this point scan that is underneath Face ID.


Well, you could implement face detection support yourself, but that’s a larger (and riskier) ML project than you probably intended to start.

I don’t think AR kit object detection will get you there, either:

And the LIDAR scanner uses a very different hardware design and scan design:
