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…
Hardware-Accelerated Geometrical Simulation of Biological and Engineered In-Air Ultrasonic Systems
Wouter Jansen, Jan Steckel
The deployment of in-air acoustic sensors for industrial monitoring and autonomous robotics has grown significantly, often drawing inspiration from biological echolocation. However…
LLM-Driven 3D Scene Generation of Agricultural Simulation Environments
Arafa Yoncalik, Wouter Jansen, Nico Huebel +2
Procedural generation techniques in 3D rendering engines have revolutionized the creation of complex environments, reducing reliance on manual design. Recent approaches using Large…
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…
Towards In-Air Ultrasonic QR Codes: Deep Learning for Classification of Passive Reflector Constellations
Wouter Jansen, Jan Steckel
In environments where visual sensors falter, in-air sonar provides a reliable alternative for autonomous systems. While previous research has successfully classified individual aco…
