Vision-Based Multi-View Cooperative Perception for UAV Swarms in GNSS-Denied Transportation Hub Reconnaissance

A discrete, vision-based cooperative perception framework utilizing a decentralized anchor-wingman architecture provides a rigorous geometric foundation for autonomous swarms, enabling downstream collision-free trajectory planning and Multi-Target Task Allocation in GNSS-denied environments.

Layered Inertial-Terrain-Visual Navigation for UAVs Under GNSS-Denied Conditions: A Case Study over the Tibetan Plateau

A UAV operating without GNSS faces unbounded inertial drift. A layered navigation architecture is evaluated in which terrain contour matching (TERCOM) provides periodic position corrections and satellite-image scene matching adds a condition-dependent precision layer. The architecture is examined through a single-traje...
