According to this picture:
the iPhone X has an infrared camera. It is primarily used for face detection but there are other uses for infrared. Can it be accessed directly?
回答1:
not via the approved iOS API library calls. But undocumented API should be possible if you guess how to do it.
回答2:
Still not sure about infrared but to read the depth information from the iPhone X TrueDepth camera, we can use the AVDepthData class and related APIs. Here's a tutorial.
回答3:
The company, reallusion.com makes a 3D animation product called 'iclone 7' which interfaces with the iPhone infrared camera. Try contacting them about how they do it. if not proprietary, they might at least give you a clue.
