The rear 3D camera will have support for Apple ARKit which is nothing but a similar feature what we saw on Project Tango based AR smartphone which uses to measure the distance between two points using the 3D sensor and Apple might even add the Portrait mode on rear camera one found on iPhone X selfie camera.
The 3D sensor on the rear camera will use the time of flight camera instead of structured light approach one found on iPhone X selfie camera.We already saw a time -of- flight camera on smartphones like Lenovo Phab 2 Pro and Asus Zenfone AR.
Google is busy working with Infineon for their Project Tango whereas Sony and Panasonic to working on the AR-based smartphone.So now, Apple has also started working on the AR-based smartphone which is scheduled to be launched in 2019.
