UAV–UGV Collaborative Localization in GNSS-Denied Large-Scale Environments: An Anchor-Free VIO–UWB Fusion with Adaptive Weighting and Outlier Suppression

Drones
In GNSS-denied large-scale outdoor environments, UAVs and UGVs that rely solely on visual–inertial odometry (VIO) suffer from accumulated global drift as the trajectory grows.

HDVIO2.0: Wind and Disturbance Estimation With Hybrid Dynamics VIO

IEEE Transactions on Robotics
Visual-inertial odometry (VIO) is widely used for state estimation in autonomous micro aerial vehicles using onboard sensors. Current methods improve VIO by incorporating a model of the translational vehicle dynamics, yet their performance degrades when faced with low-accuracy vehicle models or continuous external disturbances, like wind. Additionally,

Event/Visual/IMU Integration for UAV-Based Indoor Navigation

Proceedings
Unmanned aerial vehicle (UAV) navigation in indoor environments is challenging due to varying light conditions, the dynamic clutter typical of indoor spaces, and the absence of GNSS signals.

V2I-Based LiDAR and RSSI-Based Ranging-Assisted Visual-Inertial Odometry for Robust Ego Vehicle Localization in GPS-Denied Environments

IEEE Access
This paper proposes a two-dimensional localization framework that integrates Visual-Inertial Odometry (VIO) and roadside units (RSUs) equipped with LiDAR sensors and vehicle-to-infrastructure (V2I) communication, while opportunistically incorporating GPS

ERIK VIO, SURGEON FROM RIJEKA AT HISTORY’S CROSSROAD

Acta medico-historica Adriatica : AMHA, 2016
The fact that many famous denizens of Rijeka belong to different nationalities confirms this city’s historic multicultural image. The life story of Erik Vio (1910-1996), renowned surgeon of international reputation, reflects the fate of many displaced residents of Rijeka who left to live in exile.
