RiskFly: Frustum-Aligned Spatio-Temporal Risk Fields for One-Stage Agile Flight in Dynamic Clutter
Luxia Ai, Haopeng Chen, Yuchao Mei +2
Agile flight in unknown, cluttered, and dynamic environments requires a planner that knows where and when danger will appear, not only that a trajectory is dangerous. One-stage lea…
VIREL: Route-Local Lattice Residual Compression for Exact and Error-Bounded Floating-Point Time Series
Yue Zhang, Jiatao Lin, Haopeng Chen
Time-series databases store floating-point columns in independent pages that are written at ingest, rewritten at compaction, and decoded on every scan. Some columns must return the…
Anticipatory Risk-Guided Reinforcement Learning for Safe Flight Through Dynamic Clutter
Yuchao Mei, Guohao Zhang, Luxia Ai +2
Safe quadrotor navigation in cluttered and dynamic environments depends not only on instantaneous geometric perception, but more critically on anticipating collision risks induced…
Dynamic Airspace Management for UAVs in Evolving Urban Environments: Collaborative Coordination and Human Safety
Lin Sun, Yuhang Wang, Fan Meng Hong +3
The low-altitude economy is an emerging industry with significant development potential, in which the safety of unmanned aerial vehicle (UAV) operations is a critical challenge. Pa…
AeroMesa: Efficient Data Management System for Multi-Dimensional Spatio-Temporal Trajectories
Yue Zhang, Zizhong Ding, Lin Sun +3
The proliferation of multi-dimensional trajectory data, fueled by large-scale IoT and the emerging low-altitude economy, particularly UAV operations, drives repositories to jointly…
