ASVSim (AirSim for Surface Vehicles): A High-Fidelity Simulation Framework for Autonomous Surface Vehicle Research
Bavo Lesy, Siemen Herremans, Robin Kerstens +4
The transport industry has recently shown significant interest in unmanned surface vehicles (USVs), specifically for port and inland waterway transport. These systems can improve o…
Intelligent Road Condition Monitoring using 3D In-Air SONAR Sensing
Amber Cassimon, Robin Kerstens, Walter Daems +1
In this paper, we investigate the capabilities of in-air 3D SONAR sensors for the monitoring of road surface conditions. Concretely, we consider two applications: Road material cla…
Delay-Multiply-And-Sum Beamforming for Real-Time In-Air Acoustic Imaging
Wouter Jansen, Walter Daems, Jan Steckel
In-air acoustic imaging systems demand beamforming techniques that offer a high dynamic range and spatial resolution while also remaining robust. Conventional Delay-and-Sum (DAS) b…
Ruggedized Ultrasound Sensing in Harsh Conditions: eRTIS in the wild
Dennis Laurijssen, Wouter Jansen, Arne Aerts +2
We present eRTIS, a rugged, embedded ultrasound sensing system for use in harsh industrial environments. The system features a broadband capacitive transducer and a 32-element MEMS…
ConamArray: A 32-Element Broadband MEMS Ultrasound Transducer Array
Dennis Laurijssen, Rens Baeyens, Walter Daems +1
This paper presents the ConamArray, a compact broadband ultrasound transducer array composed of 32 MEMS loudspeakers. Unlike conventional broadband transducers, which are typically…
nRTIS: Low-Cost Real-Time 3D Sonar Imaging Circular Array Supporting Beamforming for Industrial Applications
Rens Baeyens, Dennis Laurijssen, Jan Steckel +1
Conventional ultrasonic inspection systems rely on phased arrays and high-performance computing hardware, making them costly, bulky, and unsuitable for portable or embedded use. In…
