Pointing the Way: Refining Radar-Lidar Localization Using Learned ICP Weights

no code implementations15 Sep 2023 Daniil Lisus, Johann Laconte, Keenan Burnett, Timothy D. Barfoot

Combining a proven analytical approach with a learned weight reduces localization errors in radar-lidar ICP results run on real-world autonomous driving data by up to 54. 94% in translation and 68. 39% in rotation, while maintaining interpretability and robustness.

Dynamic Lambda-Field: A Counterpart of the Bayesian Occupancy Grid for Risk Assessment in Dynamic Environments

no code implementations8 Mar 2021 Johann Laconte, Elie Randriamiarintsoa, Abderrahim Kasmi, François Pomerleau, Roland Chapuis, Christophe Debain, Romuald Aufrère

While navigating in complex urban environments, the Bayesian occupancy grid is one of the most popular types of maps, where the information of occupancy is stored as the probability of collision.
