This paper reviews recent developments of non-contact three-dimensional (3D) surface
metrology using an active structured optical probe. We focus primarily on those active non …

Indirect time-of-flight (iToF) cameras operate by illuminating a scene with modulated light
and inferring depth at each pixel by combining the back-reflected light with different gating …

Neural networks can represent and accurately reconstruct radiance fields for static 3D
scenes (eg, NeRF). Several works extend these to dynamic scenes captured with monocular …

Non-line-of-sight imaging allows objects to be observed when partially or fully occluded from
direct view, by analysing indirect diffuse reflections off a secondary relay surface. Despite …

Abstract Non-line-of-sight (NLOS) imaging is a rapidly developing research direction that
has significant applications in autonomous vehicles, remote sensing and other areas …

Time-of-flight (ToF) imaging has become a widespread technique for depth estimation,
allowing affordable off-the-shelf cameras to provide depth maps in real time. However …

Coarse depth maps can be enhanced by using the shape information from polarization
cues. We propose a framework to combine surface normals from polarization (hereafter …

Jumping spiders (Salticidae) rely on accurate depth perception for predation and navigation.
They accomplish depth perception, despite their tiny brains, by using specialized optics …

Imaging through fog has important applications in industries such as self-driving cars,
augmented driving, airplanes, helicopters, drones and trains. Here we show that time …

Abstract Non-line-of-sight (NLOS) imaging enables unprecedented capabilities in a wide
range of applications, including robotic and machine vision, remote sensing, autonomous …
