Under Pressure: Altimeter-Aided ICP for 3D Maps Consistency

ICRA 2025

We propose a novel method to enhance the accuracy of the Iterative Closest Point (ICP) algorithm by integrating altitude constraints from a barometric pressure sensor. While ICP is widely used in mobile robotics for Simultaneous Localization and Mapping (SLAM), it is susceptible to drift, especially

RTS-GT: Robotic Total Stations Ground Truthing dataset

ICRA 2024poster

Numerous datasets and benchmarks exist to assess and compare Simultaneous Localization and Mapping (SLAM) algorithms. Nevertheless, their precision must follow the rate at which SLAM algorithms improved in recent years. Moreover, current datasets fall short of comprehensive data-collection protocol…

Extrinsic calibration for highly accurate trajectories reconstruction

ICRA 2023poster

In the context of robotics, accurate ground-truth positioning is the cornerstone for the development of mapping and localization algorithms. In outdoor environments and over long distances, total stations provide accurate and precise measurements, that are unaffected by the usual factors that deteri…

Uncertainty Analysis for Accurate Ground Truth Trajectories with Robotic Total Stations

IROS 2023poster

In the context of robotics, accurate ground truth positioning is essential for the development of Simultaneous Localization and Mapping (SLAM) and control algorithms. Robotic Total Stations (RTSs) provide accurate and precise reference positions in different types of outdoor environments, especially…
