It's (comparatively) easier to calculate depth data if you have the precise distances between the two cameras. Apple knows these values, down to the millimeter.

It's (comparatively) easier to calculate depth data if you have the precise distances between the two cameras. Apple knows these values, down to the millimeter. Calculating the camera extrinsics based on two arbitrary photos has to be way harder. Maybe they got that far, and decided the results weren't as good as a neural network.
