Towards Revisiting Visual Place Recognition for Joining Submaps in Multimap SLAM
Markus Weißflog, Stefan Schubert, Peter Protzel +1
Visual SLAM is a key technology for many autonomous systems. However, tracking loss can lead to the creation of disjoint submaps in multimap SLAM systems like ORB-SLAM3. Because of…
A Credible and Robust approach to Ego-Motion Estimation using an Automotive Radar
Karim Haggag, Sven Lange, Tim Pfeifer +1
Consistent motion estimation is fundamental for all mobile autonomous systems. While this sounds like an easy task, often, it is not the case because of changing environmental cond…
Advancing Mixture Models for Least Squares Optimization
Tim Pfeifer, Sven Lange, Peter Protzel
Gaussian mixtures are a powerful and widely used tool to model non-Gaussian estimation problems. They are able to describe measurement errors that follow arbitrary distributions an…
Incrementally Learned Mixture Models for GNSS Localization
Tim Pfeifer, Peter Protzel
GNSS localization is an important part of today's autonomous systems, although it suffers from non-Gaussian errors caused by non-line-of-sight effects. Recent methods are able to m…
Expectation-Maximization for Adaptive Mixture Models in Graph Optimization
Tim Pfeifer, Peter Protzel
Non-Gaussian and multimodal distributions are an important part of many recent robust sensor fusion algorithms. In difference to robust cost functions, they are probabilistically f…
