On the Consistency of Multi-Robot Cooperative Localization: A Transformation-Based Approach

RA-L 2025

This letter investigates the inconsistency problem caused by the mismatch of observability properties commonly found in multi-robot cooperative localization (CL) and simultaneous localization and mapping (SLAM). To address this issue, we propose a transformation-based approach that introduces a line

T-ESKF: Transformed Error-State Kalman Filter for Consistent Visual-Inertial Navigation

RA-L 2025

This paper presents a novel approach to address the inconsistency problem caused by observability mismatch in visual-inertial navigation systems (VINS). The key idea involves applying a linear time-varying transformation to the error-state within the Error-State Kalman Filter (ESKF). This transforma

Consistent Distributed Cooperative Localization: A Coordinate Transformation Approach

IROS 2024poster

This paper addresses the consistency issue of multi-robot distributed cooperative localization. We introduce a consistent distributed cooperative localization algorithm conducting state estimation in a transformed coordinate. The core idea involves a linear time-varying coordinated transformation to…

KD-EKF: A Consistent Cooperative Localization Estimator Based on Kalman Decomposition

IROS 2023poster

In this paper, we revisit the inconsistency problem of EKF-based cooperative localization (CL) from the perspective of system decomposition. By transforming the linearized system used by the standard EKF into its Kalman observable canonical form, the observable and unobservable components of the sys…
