In order to meet the task requirements of coverage detection of interest areas in the battlefield environment, this paper proposes a multiUAV cooperative detection task allocation strategy based on regional coverage. Firstly, the target track point of the UAV in the region of interest is determined by the minimum circle coverage method. Secondly, the multiUAV collaborative task planning is carried out, and a time allocation model is further established based on the target allocation model, and then the improved gray wolf algorithm is used to solve the task assignment model, and finally the resource optimization allocation decision scheme is obtained. The simulation results show that the proposed algorithm is good at convergence speed compared with other algorithms, and is advantageous to the solution of optimal allocation of regional coverage detection resources.
