Map Management for Efficient Long-Term Visual Localization in Outdoor Environments
Mathias Bürki, Marcin Dymczyk, Igor Gilitschenski +3
We present a complete map management process for a visual localization system designed for multi-vehicle long- term operations in resource constrained outdoor environments. Outdoor…
Appearance-Based Landmark Selection for Efficient Long-Term Visual Localization
Mathias Bürki, Igor Gilitschenski, Elena Stumm +2
We present an online landmark selection method for distributed long-term visual localization systems in bandwidth-constrained environments. Sharing a common map for online localiza…
LandmarkBoost: Efficient Visual Context Classifiers for Robust Localization
Marcin Dymczyk, Igor Gilitschenski, Juan Nieto +3
The growing popularity of autonomous systems creates a need for reliable and efficient metric pose retrieval algorithms. Currently used approaches tend to rely on nearest neighbor…
Learning 3D Segment Descriptors for Place Recognition
Andrei Cramariuc, Renaud Dubé, Hannes Sommer +2
In the absence of global positioning information, place recognition is a key capability for enabling localization, mapping and navigation in any environment. Most place recognition…
Why and How to Avoid the Flipped Quaternion Multiplication
Hannes Sommer, Igor Gilitschenski, Michael Bloesch +3
Over the last decades quaternions have become a crucial and very successful tool for attitude representation in robotics and aerospace. However, there is a major problem that is co…
Visual-inertial self-calibration on informative motion segments
Thomas Schneider, Mingyang Li, Michael Burri +3
Environmental conditions and external effects, such as shocks, have a significant impact on the calibration parameters of visual-inertial sensor systems. Thus long-term operation o…
