COVINS-G: A Generic Back-end for Collaborative Visual-Inertial SLAM

1 code implementation17 Jan 2023 Manthan Patel, Marco Karrer, Philipp Bänninger, Margarita Chli

The paradigm of a centralized architecture is well established, with the robots (i. e. agents) running Visual-Inertial Odometry (VIO) onboard while communicating relevant data, such as e. g. Keyframes (KFs), to a central back-end (i. e. server), which then merges and optimizes the joint maps of the agents.

COVINS: Visual-Inertial SLAM for Centralized Collaboration

1 code implementation12 Aug 2021 Patrik Schmuck, Thomas Ziegler, Marco Karrer, Jonathan Perraudin, Margarita Chli

Collaborative SLAM enables a group of agents to simultaneously co-localize and jointly map an environment, thus paving the way to wide-ranging applications of multi-robot perception and multi-user AR experiences by eliminating the need for external infrastructure or pre-built maps.

Hough2Map -- Iterative Event-based Hough Transform for High-Speed Railway Mapping

1 code implementation16 Feb 2021 Florian Tschopp, Cornelius von Einem, Andrei Cramariuc, David Hug, Andrew William Palmer, Roland Siegwart, Margarita Chli, Juan Nieto

As a basis for a localization system we propose a complete on-board mapping pipeline able to map robust meaningful landmarks, such as poles from power lines, in the vicinity of the vehicle.

Distributed Variable-Baseline Stereo SLAM from two UAVs

no code implementations10 Sep 2020 Marco Karrer, Margarita Chli

VIO has been widely used and researched to control and aid the automation of navigation of robots especially in the absence of absolute position measurements, such as GPS.

Aerial Single-View Depth Completion with Image-Guided Uncertainty Estimation

2 code implementations17 Jan 2020 Lucas Teixeira, Martin R. Oswald, Marc Pollefeys, Margarita Chli

In this paper, we propose a depth completion and uncertainty estimation approach that better handles the challenges of aerial platforms, such as large viewpoint and depth variations, and limited computing resources.

Learning Deep Descriptors With Scale-Aware Triplet Networks

no code implementations CVPR 2018 Michel Keller, Zetao Chen, Fabiola Maffra, Patrik Schmuck, Margarita Chli

Research on learning suitable feature descriptors for Computer Vision has recently shifted to deep learning where the biggest challenge lies with the formulation of appropriate loss functions, especially since the descriptors to be learned are not known at training time.
