A new frequency-modulated continuous-wave (FMCW) Lidar system is proposed to measure
distance and velocity unambiguously by using a frequency-shifted probe light. The optical …

In the field of industrial precision measurement, the localization and velocity information
acquisition of moving targets still depend on short-term displacement measurements using …

The growing ubiquity of drones has raised concerns over the ability of traditional air-space
monitoring technologies to accurately characterise such vehicles. Here, we present a CNN …

3D time-of-flight (ToF) image sensors are used widely in applications such as self-driving
cars, augmented reality (AR), and robotics. When implemented with single-photon …

Single-photon avalanche diodes (SPADs) are novel image sensors that record the arrival of
individual photons at extremely high temporal resolution. In the past, they were only …

Abstract Single-photon Light Detection and Ranging (LiDAR) systems are often equipped
with an array of detectors for improved spatial resolution and sensing speed. However given …

In non-line-of-sight (NLOS) imaging, the spatial information of hidden targets is
reconstructed from the time-of-light (TOF) of the multiple bounced signal photons. The need …

The 3D imaging-based model reconstruction technology is being applied in various aspects
of fruit planting management, picking, transportation, and promoting fruit industry automation …

This paper proposes a Bayesian approach to enable single photon avalanche diode (SPAD)
arrays to be used as pseudo event cameras that report changes in the scene. Motivated by …

Occlusion, rotation and other factors affect human motion structure because of the
incomplete acquired image sequence, resulting in poor performance of non-rigid three …
