A Geometric Framework for Absolute Pose and Velocity Estimation with Event Cameras
Zibin Liu, Shunkun Liang, Banglei Guan +3
Despite the rapid advancements in event-based motion estimation, current geometric methods primarily focus on velocity estimation. However, absolute pose estimation, which is equal…
An Opticalmechanics Framework for Dynamic Estimation of Multibody Systems
Banglei Guan, Xuanyu Bai, Qingquan Chen +5
Conventional dynamics analysis of the human body is often constrained by the need for contact force and torque sensors and controlled laboratory environments. To address this issue…
Virtual-point-based Solutions to Handle Generalized Absolute Pose Problem
Bin Li, Banglei Guan, Shunkun Liang +1
Multi-camera systems are increasingly adopted in robotics and autonomous navigation for their wide field of view, flexibility, and fault tolerance. Nevertheless, existing PnP solve…
Minimal Solvers for Full-DoF Motion Estimation from Asynchronous Differential SfM
Shuo Pan, Banglei Guan, Bin Li +5
As a bio-inspired intelligent sensor, event cameras have introduced a new paradigm in the intelligent perception of spatiotemporal information and visual motion estimation, charact…
Event-driven dynamic trajectories reconstruction and measurement of mechanical parameters for fragments
Haoyang Li, Banglei Guan, Muxi Zha +4
During warhead detonation, high-density, high-speed, and mutually occluded fragments are generated. Their mechanical parameters (position, velocity, kinetic energy) directly determ…
Trajectory Optimization in Single and Dual-UAV Bearing-Only Target Localization
Zhijian Xiao, Huayu Huang, Bin Li +2
Bearing-only target localization is a fundamental problem in optical measurement and finds extensive applications in unmanned aerial vehicle (UAV) technology. Effective trajectory…
