U-BEV: Height-aware Bird's-Eye-View Segmentation and Neural Map-based Relocalization

no code implementations20 Oct 2023 Andrea Boscolo Camiletto, Alfredo Bochicchio, Alexander Liniger, Dengxin Dai, Abel Gawel

Efficient relocalization is essential for intelligent vehicles when GPS reception is insufficient or sensor-based localization fails.

SCIM: Simultaneous Clustering, Inference, and Mapping for Open-World Semantic Scene Understanding

1 code implementation21 Jun 2022 Hermann Blum, Marcus G. Müller, Abel Gawel, Roland Siegwart, Cesar Cadena

In order to operate in human environments, a robot's semantic perception has to overcome open-world challenges such as novel objects and domain gaps.

Self-Improving Semantic Perception for Indoor Localisation

1 code implementation4 May 2021 Hermann Blum, Francesco Milano, René Zurbrügg, Roland Siegward, Cesar Cadena, Abel Gawel

We find memory replay an effective measure to reduce forgetting and show how the robotic system can improve even when switching between different environments.

A Fully-Integrated Sensing and Control System for High-Accuracy Mobile Robotic Building Construction

no code implementations4 Dec 2019 Abel Gawel, Hermann Blum, Johannes Pankert, Koen Krämer, Luca Bartolomei, Selen Ercan, Farbod Farshidian, Margarita Chli, Fabio Gramazio, Roland Siegwart, Marco Hutter, Timothy Sandy

We present a fully-integrated sensing and control system which enables mobile manipulator robots to execute building tasks with millimeter-scale accuracy on building construction sites.

Learning Densities in Feature Space for Reliable Segmentation of Indoor Scenes

no code implementations1 Aug 2019 Nicolas Marchal, Charlotte Moraldo, Roland Siegwart, Hermann Blum, Cesar Cadena, Abel Gawel

Foreground objects are therefore detected as areas in an image for which the descriptors are unlikely given the background distribution.

3D Multi-Robot Patrolling with a Two-Level Coordination Strategy

1 code implementation23 Jun 2019 Luigi Freda, Mario Gianni, Fiora Pirri, Abel Gawel, Renaud Dube, Roland Siegwart, Cesar Cadena

This target selection relies on a shared idleness representation and a coordination mechanism preventing topological conflicts.

Modular Sensor Fusion for Semantic Segmentation

1 code implementation30 Jul 2018 Hermann Blum, Abel Gawel, Roland Siegwart, Cesar Cadena

Sensor fusion is a fundamental process in robotic systems as it extends the perceptual range and increases robustness in real-world operations.

X-View: Graph-Based Semantic Multi-View Localization

no code implementations28 Sep 2017 Abel Gawel, Carlo Del Don, Roland Siegwart, Juan Nieto, Cesar Cadena

Our findings show that X-View is able to globally localize aerial-to-ground, and ground-to-ground robot data of drastically different view-points.
