Abstract

Magic stairs, a staircase loop, is a kind of optical illusion. Such cognitive paradox is an inherent defect when two-dimensional (2D) images represent high-dimensional information. For this demand, we demonstrate an intelligent depth-sensing system prototype applicable for diverse scenes, a switchable stereo vision system that adopts a 60 × 60 achromatic meta-lens array to measure depth over a 30-cm range with the support of deep learning. This system combines a light field camera and a structured light system to adapt to all light levels. The design, application, and experimental verification of the intelligent depth-sensing meta-device are reported in this talk.
