Automatic Spatial Calibration of Near-Field MIMO Radar With Respect to Optical Sensors

no code implementations16 Mar 2024 Vanessa Wirth, Johanna Bräunig, Danti Khouri, Florian Gutsche, Martin Vossiek, Tim Weyrich, Marc Stamminger

In contrast, we propose a novel, joint calibration approach for optical RGB-D sensors and MIMO radars that is designed to operate in the radar's near-field range, within decimeters from the sensors.

3D-Printed Dielectric Image Lines towards Chip-to-Chip Interconnects for subTHz-Applications

no code implementations6 Mar 2024 Leonhard Hahn, Tim Pfahler, Tobias Bader, Gerald Gold, Martin Vossiek, Christian Carlowitz

This paper reports on 3D-printed dielectric image lines for low-loss subTHz applications between 140 and 220 GHz.

Radar-Based Recognition of Static Hand Gestures in American Sign Language

no code implementations20 Feb 2024 Christian Schuessler, Wenxuan Zhang, Johanna Bräunig, Marcel Hoffmann, Michael Stelzig, Martin Vossiek

This emphasizes the practicality of our methodology in overcoming data scarcity challenges and advancing the field of automatic gesture recognition in VR and HCI applications.

UAV Formation Optimization for Communication-assisted InSAR Sensing

no code implementations12 Nov 2023 Mohamed-Amine Lahmeri, Victor Mustieles-Pérez, Martin Vossiek, Gerhard Krieger, Robert Schober

To this end, we adopt as sensing performance metrics the interferometric coherence, i. e., the local correlation between the two co-registered UAV radar images, and the height of ambiguity (HoA), which together are a measure for the accuracy with which the InSAR system can estimate the height of ground objects.

A Realistic Radar Ray Tracing Simulator for Hand Pose Imaging

no code implementations28 Jul 2023 Johanna Bräunig, Christian Schüßler, Vanessa Wirth, Marc Stamminger, Ingrid Ullmann, Martin Vossiek

With the increasing popularity of human-computer interaction applications, there is also growing interest in generating sufficiently large and diverse data sets for automatic radar-based recognition of hand poses and gestures.

Super-Resolution Radar Imaging with Sparse Arrays Using a Deep Neural Network Trained with Enhanced Virtual Data

1 code implementation16 Jun 2023 Christian Schuessler, Marcel Hoffmann, Martin Vossiek

The key to this performance is that the DNN is trained using realistic simulation data that perfectly mimic a given sparse antenna radar array hardware as the input.

Implementation of Real-Time Automotive SAR Imaging

no code implementations16 Jun 2023 Marcel Hoffmann, Theresa Noegel, Christian Schüßler, Lars Schwenger, Peter Gulden, Dietmar Fey, Martin Vossiek

This paper presents measures to reduce the computation time of automotive synthetic aperture radar (SAR) imaging to achieve real-time capability.

Achieving Efficient and Realistic Full-Radar Simulations and Automatic Data Annotation by exploiting Ray Meta Data of a Radar Ray Tracing Simulator

no code implementations23 May 2023 Christian Schüßler, Marcel Hoffmann, Vanessa Wirth, Björn Eskofier, Tim Weyrich, Marc Stamminger, Martin Vossiek

This approach allows not only almost perfect annotations possible, but also allows the annotation of exotic effects, such as multi-path effects or to label signal parts originating from different parts of an object.

ShaRPy: Shape Reconstruction and Hand Pose Estimation from RGB-D with Uncertainty

no code implementations17 Mar 2023 Vanessa Wirth, Anna-Maria Liphardt, Birte Coppers, Johanna Bräunig, Simon Heinrich, Sigrid Leyendecker, Arnd Kleyer, Georg Schett, Martin Vossiek, Bernhard Egger, Marc Stamminger

Therefore, we propose ShaRPy, the first RGB-D Shape Reconstruction and hand Pose tracking system, which provides uncertainty estimates of the computed pose, e. g., when a finger is hidden or its estimate is inconsistent with the observations in the input, to guide clinical decision-making.
