Topology-Aware Handover for Multi-UAV Vehicle Tracking

A new framework addresses trajectory fragmentation in multi-UAV vehicle tracking for intelligent transportation systems. The system, described in arXiv preprint 2605.15779, introduces a lightweight Topology-Based Spatiotemporal Handover mechanism to maintain global identity persistence across multiple drone fields of view. It overcomes limitations of appearance-based re-identification in nadir views by using spatial topology and temporal cues, enabling real-time multi-camera multi-vehicle tracking. The approach is designed to support network-level analysis such as origin-destination estimation, which is hindered by current isolated data silos. A high-throughput parallel pipeline ensures scalability for continuous monitoring.
