Compact light field photography towards versatile three-dimensional vision

High-speed, accurate three-dimensional (3D) sensing across a wide range of distances and with robustness to occlusions remains a challenge. This paper introduces compact light field photography (CLIP) for efficient large-scale light field acquisition using simple optics and few sensors. CLIP handles various sensor formats (2D area to single-point detectors), drastically reducing data load. The authors demonstrate CLIP's effectiveness in multi-view time-of-flight imaging for snapshot 3D imaging with extended depth range and occlusion handling, and in real-time non-line-of-sight (NLOS) 3D vision using curved/disconnected surfaces. CLIP promises advancements in high-speed 3D imaging across various fields.
