libRSF - Version 2.0

March 2021

Today, we released a big update of our robust sensor fusion library libRSF. In conjunction to our recent RA-L paper we released a novel Gaussian Mixture representation for factor graphs and much more.

Vistiting the PolyU

November 2019

I had the pleasure to visit the Intelligent Positioning and Navigation Laboratory at the Honk Kong PolyU to spend two weeks on robust sensor fusion in the urban canyons of Hong Kong. I also gave a seminar talk on "Incrementally learned Mixture Models for GNSS Localization in Urban Areas".
Thanks to Dr. Hsu and Weisong Wen for the invitation and the great time in HK.

libRSF - A Robust Sensor Fusion Library

February 2019

Please have a look at our new sensor fusion library libRSF. It's all about robust factor graphs for localization.

Research Interests

I currently focus on sensor fusion algorithms which are robust against measurements that are subject to a non-Gaussian error distribution. With tools like non-linear optimization, maximum-likelihood methods or Bayesian inference I want to create probabilistic plausible algorithms that are able to adapt themselves to unforeseen conditions and improve the robustness of today's autonomous systems.

Only the possibility to evaluate algorithms on the data of others makes research comparable. Therefore, I want to provide the datasets of my publications below.
