SceneGraphLoc: Cross-Modal Coarse Visual Localization on 3D Scene Graphs

no code implementations30 Mar 2024 Yang Miao, Francis Engelmann, Olga Vysotska, Federico Tombari, Marc Pollefeys, Dániel Béla Baráth

We introduce a novel problem, i. e., the localization of an input image within a multi-modal reference map represented by a database of 3D scene graphs.

Vital Signs Estimation Using a 26 GHz Multi-Beam Communication Testbed

no code implementations19 Nov 2023 Miquel Sellés Valls, Sofie Pollin, Ying Wang, Rizqi Hersyandika, Andre Kokkeler, Yang Miao

The results show that the estimated breath rate and heart rate reach below 2 beats per minute (bpm) error compared to the reference captured by on-body sensor for the single-person monostatic sensing scenario with body-transceiver distance up to 2 m, and the two-person bistatic sensing scenario with BS-UE distance up to 4 m. The presented work does not optimize the OFDM waveform parameters for sensing; it demonstrates a promising JCAS proof-of-concept in contact-free vital sign monitoring using mmWave multi-beam communication systems.

Volumetric Semantically Consistent 3D Panoptic Mapping

1 code implementation26 Sep 2023 Yang Miao, Iro Armeni, Marc Pollefeys, Daniel Barath

We introduce an online 2D-to-3D semantic instance mapping algorithm aimed at generating comprehensive, accurate, and efficient semantic 3D maps suitable for autonomous agents in unstructured environments.

Enhancing Vital Sign Estimation Performance of FMCW MIMO Radar by Prior Human Shape Recognition

no code implementations16 Mar 2023 Hadi Alidoustaghdam, Min Chen, Ben Willetts, Kai Mao, André Kokkeler, Yang Miao

Additionally, human's random body movements deteriorate the estimation of breathing and heart rates, therefore the information of the chest location and a narrow radar beam toward the chest are demanded for more accurate vital sign estimation.

Intelligent Blockage Recognition using Cellular mmWave Beamforming Data: Feasibility Study

no code implementations30 Oct 2022 Bram van Berlo, Yang Miao, Rizqi Hersyandika, Nirvana Meratnia, Tanir Ozcelebi, Andre Kokkeler, Sofie Pollin

Joint Communication and Sensing (JCAS) is envisioned for 6G cellular networks, where sensing the operation environment, especially in presence of humans, is as important as the high-speed wireless connectivity.

Multibeam Sparse Tiled Planar Array for Joint Communication and Sensing

no code implementations19 Sep 2022 Hadi Alidoustaghdam, André Kokkeler, Yang Miao

We propose to first solve the optimization by the maximum entropy in the phase centers of tiles in the array; then we perform sparse subarray selection leveraging the geometry of the sunflower array.

Contact-Free Multi-Target Tracking Using Distributed Massive MIMO-OFDM Communication System: Prototype and Analysis

no code implementations23 Aug 2022 Chenglong Li, Sibren De Bast, Yang Miao, Emmeric Tanghe, Sofie Pollin, Wout Joseph

To evade the complex association problem of distributed massive MIMO-based MTT, we propose to use a complex Bayesian compressive sensing (CBCS) algorithm to estimate the targets' locations based on the extracted target-of-interest CSI signal directly.

Guard Beam: Protecting mmWave Communication through In-Band Early Blockage Prediction

no code implementations14 Aug 2022 Rizqi Hersyandika, Yang Miao, Sofie Pollin

We derive a channel model for the pre-shadowing event, design a moving blockage detection algorithm for the guard beam, and evaluate the performance of the guard beam theoretically and experimentally based on the measurement campaign using our mmWave testbed.

Dynamic mmWave Channel Emulation in a Cost-Effective MPAC with Dominant-Cluster Concept

no code implementations21 Aug 2020 Xuesong Cai, Yang Miao, Jinxing Li, Fredrik Tufvesson, Gert Frølund Pedersen, Wei Fan

In this contribution, we firstly illustrate the dominant-cluster(s) concept, where the non-dominant clusters in the mmWave channels are pruned, for mmWave 5G devices applying massive MIMO beamforming.
