A Buddy Temporal-Spatial Calibration Method for Airborne Sensors in Multi-UAV Systems

RA-L 2024

The temporal and spatial relationships among various onboard sensors are crucial for ensuring the accuracy of visual observations carried out by the multiple unmanned aerial vehicles (multi-UAV) system. To leverage the integration within the multi-UAV system, we propose a buddy calibration method fo

Torque Ripple Reduction in Quasi-Direct Drive Motors Through Angle-Based Repetitive Learning Observer and Model Predictive Torque Controller

IROS 2024poster

Torque ripple reduction in quasi-direct drive (QDD) motors is crucial in their robotic applications for dynamic locomotion and dexterous manipulation. In this paper, we present a novel approach for reducing torque ripples of QDD motors, which integrates an angle-based repetitive learning observer (A…

Simplified Mirror-Based Camera Pose Computation via Rotation Averaging

CVPR 2015poster

We propose a novel approach to compute the camera pose with respect to a reference object given only mirrored views. The latter originate from a planar mirror at different unknown poses. This problem is highly relevant in several extrinsic camera calibration scenarios, where the camera cannot see th…
