Efficient Feature-Free Initialization for Monocular Visual-Inertial Systems Using a Feed-Forward 3D Model
Yuantai Zhang, Jiaqi Yang, Huajian Zeng +5
Fast and reliable initialization is critical for monocular visual-inertial navigation systems (VINS), as it establishes the starting conditions for subsequent state estimation. Des…
FlowHOI: Flow-based Semantics-Grounded Generation of Hand-Object Interactions for Dexterous Robot Manipulation
Huajian Zeng, Lingyun Chen, Jiaqi Yang +4
Recent vision-language-action (VLA) models can generate plausible end-effector motions, yet they often fail in long-horizon, contact-rich tasks because the underlying hand-object i…
PO-GVINS: Tightly Coupled GNSS-Visual-Inertial Integration with Pose-Only Representation
Zhuo Xu, Feng Zhu, Zihang Zhang +4
Accurate and reliable positioning is crucial for perception, decision-making, and other high-level applications in autonomous driving, unmanned aerial vehicles, and intelligent rob…
On State Estimation in Multi-Sensor Fusion Navigation: Optimization and Filtering
Feng Zhu, Zhuo Xu, Xveqing Zhang +3
The essential of navigation, perception, and decision-making which are basic tasks for intelligent robots, is to estimate necessary system states. Among them, navigation is fundame…
