Learning Cross-View Semantic Priors for Single-Reference Unseen Object Pose Estimation
Jiahong Chen, Jinghao Wang, Ziwen Wang +3
Single-reference unseen object 6D pose estimation reduces object onboarding by estimating poses of arbitrary novel objects from only one reference view. Recent correspondence-based…
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…
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…
A Pose-only Geometric Constraint for Multi-Camera Pose Adjustment
Shunkun Liang, Banglei Guan, Bin Li +2
Multi-camera systems offer rich observation capabilities for visual navigation and 3D scene reconstruction; however, the resulting feature redundancy often compromises computationa…
