The objective of coverage path planning is to ensure that Unmanned Aerial Vehicles (UAVs) achieve complete coverage of the target area. Previous studies assigned UAVs the task of covering each sub-area separately. However, this study proposes a new methodology in which two UAVs collaborate across the entire search area, achieving coverage tasks more flexibly while enhancing efficiency. This paper aims to address the high cost of traditional UAV coverage path planning by proposing a dual-UAVcoverage path planning algorithm based on Q-Learning. To reduce the time taken for the process, a grid-based rotating area partitioning algorithm is used to minimize the search area. The path planning is transformed into a multi-objective function optimisation problem, and the Double-Q-Learning algorithm balances global search and local exploitation, iteratively optimising the path with a total cost function that considers distance and turning costs. The simulation results demonstrate that the proposed algorithm can achieve complete coverage of different target areas with a lower total cost.
