Non-line of Sight Transient Rendering

Jornada de Jóvenes Investigadores del I3A, 2022
Non-line of sight imaging reconstructs hidden geometry using time-resolved measurements of indirect diffuse reflections emitted by a laser. To help develop new applications, we simulate light transport in these occluded scenes and introduce a set of simple, yet effective subpath sampling techniques for efficiency, with an open-source implementation.

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Single-scatter channel impulse response model of non-line-of-sight ultraviolet communications [PDF]

, 2022
Previous studies on the temporal characteristics of single-scatter transmission in non-line-of-sight (NLOS) ultraviolet communications (UVC) were based on the prolate-spheroidal coordinate system.

Wireless sensor indoor positioning based on an improved particle filter algorithm

International Journal of Distributed Sensor Networks, 2020
Positioning by wireless sensor network is one of its main functions and has been widely used in many fields. However, when signal propagation is hindered, serious errors, non-line-of-sight errors, occur.

An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor

Advanced Robotics Research, EarlyView.
Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...

Coherent control of light for non-line-of-sight imaging [PDF]

, 2019
Non-line-of-sight (NLOS) imaging relies on collecting light that is rendered incoherent from the multiple scattering events and is then post-processed to provide an estimate of the hidden scene. Here we employ coherent phase control of the outgoing laser

Few-shot Non-line-of-sight Imaging with Signal-surface Collaborative Regularization [PDF]

, 2022
The non-line-of-sight imaging technique aims to reconstruct targets from multiply reflected light. For most existing methods, dense points on the relay surface are raster scanned to obtain high-quality reconstructions, which requires a long acquisition ...

An Adaptive Fading CKF-Based Strapdown Rotating Projectile Line-of-Sight Rate Filtering Algorithm [PDF]

Hangkong bingqi
In response to the strong coupling between line-of-sight angular rate and attitude error in the output of the strapdown rotating projectile, a method based on adaptive fading volume covariance Kalman filtering (AFCKF) is proposed.
