First, a 3D model of the construction site is reconstructed, and inspection viewpoints for UAV flights are generated by optimizing safety inspection strategies. Then, a hierarchical path planning framework is established: the lower-level planner strictly enforces real-time safety obstacle avoidance strategies, while the higher-level planner focuses on global planning to meet inspection requirements. Finally, both simulation and real project studies are conducted to verify the feasibility of the method. Results from the real project show that the effective coverage area is increased by 39.01 % compared with traditional methods.
