S3KF: Spherical State-Space Kalman Filtering for Panoramic 3D Multi-Object Tracking
Zhongyuan Liu, Shaonan Yu, Jianping Li +5
Panoramic multi-object tracking is important for industrial safety monitoring, wide-area robotic perception, and infrastructure-light deployment in large workspaces. In these setti…
OmniVLN: Omnidirectional 3D Perception and Token-Efficient LLM Reasoning for Visual-Language Navigation across Air and Ground Platforms
Zhongyuang Liu, Min He, Shaonan Yu +5
Language-guided embodied navigation requires an agent to interpret object-referential instructions, search across multiple rooms, localize the referenced target, and execute reliab…
Accurate Calibration and Robust LiDAR-Inertial Odometry for Spinning Actuated LiDAR Systems
Zijie Chen, Xiaowei Liu, Yong Xu +3
Accurate calibration and robust localization are fundamental for downstream tasks in spinning actuated LiDAR applications. Existing methods, however, require parameterizing extrins…
Adaptive Motorized LiDAR Scanning Control for Robust Localization with OpenStreetMap
Jianping Li, Kaisong Zhu, Zhongyuan Liu +4
LiDAR-to-OpenStreetMap (OSM) localization has gained increasing attention, as OSM provides lightweight global priors such as building footprints. These priors enhance global consis…
AEOS: Active Environment-aware Optimal Scanning Control for UAV LiDAR-Inertial Odometry in Complex Scenes
Jianping Li, Xinhang Xu, Zhongyuan Liu +3
LiDAR-based 3D perception and localization on unmanned aerial vehicles (UAVs) are fundamentally limited by the narrow field of view (FoV) of compact LiDAR sensors and the payload c…
LiMo-Calib: On-Site Fast LiDAR-Motor Calibration for Quadruped Robot-Based Panoramic 3D Sensing System
Jianping Li, Zhongyuan Liu, Xinhang Xu +4
Conventional single LiDAR systems are inherently constrained by their limited field of view (FoV), leading to blind spots and incomplete environmental awareness, particularly on ro…
