Abstract
This document describes techniques to enhance depth estimation accuracy using foldable device cameras. Modern smartphones use multiple cameras for depth estimation via stereo vision, which relies on the distance between cameras. Conventional, bar-shaped smartphones have a relatively small distance between cameras, leading to lower depth accuracy for distant objects. Foldable devices, when unfolded (open), allow for a much larger distance between the rear camera and the outward-facing selfie camera. This greater separation is leveraged for accurate depth estimation through triangulation, substantially reducing estimation error. The described techniques are applicable to devices with various foldable form factors.
