Aion: Towards Hierarchical 4D Scene Graphs with Temporal Flow Dynamics

ICRA 2026poster

Autonomous navigation in dynamic environments requires spatial representations that capture both semantic structure and temporal evolution. 3D Scene Graphs (3DSGs) provide hierarchical multi-resolution abstractions that encode geometry and semantics, but existing extensions toward dynamics largely f…

G-Loc: Tightly-Coupled Graph Localization With Prior Topo-Metric Information

RA-L 2024

Localization in already mapped environments is a critical component in many robotics and automotive applications, where previously acquired information can be exploited along with sensor fusion to provide robust and accurate localization estimates. In this letter, we offer a new perspective on map-b

A General Relationship Between Optimality Criteria and Connectivity Indices for Active Graph-SLAM

RA-L 2023

Quantifying uncertainty is a key stage in active simultaneous localization and mapping (SLAM), as it allows to identify the most informative actions to execute. However, dealing with full covariance or even Fisher information matrices (FIMs) is computationally heavy and easily becomes intractable fo
