Associating Uncertainty to Extended Poses for on Lie Group IMU Preintegration with Rotating Earth
Martin Brossard, Axel Barrau, Paul Chauchat +1
The recently introduced matrix group SE2(3) provides a 5x5 matrix representation for the orientation, velocity and position of an object in the 3-D space, a triplet we call "extend…
A Code for Unscented Kalman Filtering on Manifolds (UKF-M)
Martin Brossard, Axel Barrau, Silvere Bonnabel
The present paper introduces a novel methodology for Unscented Kalman Filtering (UKF) on manifolds that extends previous work by the authors on UKF on Lie groups. Beyond filtering…
Multi-frequency calibration for DOA estimation with distributed sensors
Martin Brossard, Virginie Ollier, Mohammed Nabil El Korso +2
In this work, we investigate direction finding in the presence of sensor gain uncertainties and directional perturbations for sensor array processing in a multi-frequency scenario.…
Denoising IMU Gyroscopes with Deep Learning for Open-Loop Attitude Estimation
Martin Brossard, Silvere Bonnabel, Axel Barrau
This paper proposes a learning method for denoising gyroscopes of Inertial Measurement Units (IMUs) using ground truth data, and estimating in real time the orientation (attitude)…
A New Approach to 3D ICP Covariance Estimation
Martin Brossard, Silvere Bonnabel, Axel Barrau
In mobile robotics, scan matching of point clouds using Iterative Closest Point (ICP) allows estimating sensor displacements. It may prove important to assess the associated uncert…
AI-IMU Dead-Reckoning
Martin Brossard, Axel Barrau, Silvère Bonnabel
In this paper we propose a novel accurate method for dead-reckoning of wheeled vehicles based only on an Inertial Measurement Unit (IMU). In the context of intelligent vehicles, ro…
