RTISSLAM-3D: Full 6-DoF SLAM With an In-Air 3D Imaging Sonar
Jan Steckel, Vincent Katter, Wouter Jansen
Echolocating bats navigate dense forests using sonar alone, and in-air 3D imaging sonars now capture the entire frontal hemisphere with every pulse. Sonar SLAM, however, has so far…
RTISSLAM: In-air Imaging Sonar SLAM using a Robust Pose Graph and Occupancy Grid Mapping
Jan Steckel
Sonar was one of the first sensors with which mobile robots built maps, and in-air sonar keeps working where cameras and lidar fail, in darkness, smoke, dust and next to glass. Cla…
Self-Supervised Deconvolution of In-Air Sonar Images Using Sensor Ego-Motion
Jan Steckel
Broadband in-air sonar sensors with a sparse microphone array form images through delay-and-sum beamforming, which leaves high sidelobes and an angular resolution that degrades str…
BatSLAM 2.0: Sequence-Verified Sonar Place Recognition in a Robust Pose Graph
Jan Steckel
Echolocating bats can navigate dark and cluttered spaces using echolocation. Over a decade ago, BatSLAM showed that a robot with a biomimetic binaural sonar can build a topological…
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…
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…
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…
Stabilized Adaptive Steering for 3D Sonar Microphone Arrays with IMU Sensor Fusion
Wouter Jansen, Dennis Laurijssen, Jan Steckel
This paper presents a novel software-based approach to stabilizing the acoustic images for in-air 3D sonars. Due to uneven terrain, traditional static beamforming techniques can be…
Semantic Landmark Detection & Classification Using Neural Networks For 3D In-Air Sonar
Wouter Jansen, Jan Steckel
In challenging environments where traditional sensing modalities struggle, in-air sonar offers resilience to optical interference. Placing a priori known landmarks in these environ…
EchoPT: A Pretrained Transformer Architecture that Predicts 2D In-Air Sonar Images for Mobile Robotics
Jan Steckel, Wouter Jansen, Nico Huebel
The predictive brain hypothesis suggests that perception can be interpreted as the process of minimizing the error between predicted perception tokens generated by an internal worl…
SonoTraceLab -- A Raytracing-Based Acoustic Modelling System for Simulating Echolocation Behavior of Bats
Wouter Jansen, Jan Steckel
Echolocation is the prime sensing modality for many species of bats, who show the intricate ability to perform a plethora of tasks in complex and unstructured environments. Underst…
