Dual-Scale Grid-Based Adaptive Trajectory Planning for UAVs in Urban Low-Altitude Airspace
A dual-scale grid-based trajectory planning approach that separates the global routing and local refinement of UAV trajectories, and proposes a priority-driven dual-grid Theta* with adaptive relaxation (DGTAR) to balance the global planning efficiency and local obstacle avoidance accuracy.
