In order to solve the problem of multi-UAV mission load imbalance and path planning in the field and disaster-stricken areas,a load-balanced multi-UAV coverage path algorithm based on the coverage path generation algorithm STC and the balanced cut algorithm is proposed.Based on the STC algorithm,the path partitioning process is optimized,the balanced cut algorithm is designed to iteratively optimize the load weights of the path partitioning,which solves the problem of uneven workload of multiple UAVs in completing the coverage of the target area.The feasibility of the method is verified through comparative simulation experiments.The results show that the BmCPP algorithm can find the optimal path for multiple UAVs and effectively balance the load of multiple UAVs under limited resource constraints.
