The unmanned aerial vehicle (UAV) has huge application potential in disaster rescue, natural detection, and military reconnaissance. In these scenarios, task assignment is essential and facing the problem of NP-hard, and as the scale of the Multi-UAV system increase, it is harder to solve the problem. In this paper, a CSCM-SA (Cosine Similarity Clustering Method- Simulated Annealing) is proposed. Firstly, the cosine similarity clustering method is used for pre-clustering of large-scale targets; Secondly, simulated annealing is employed to optimize routers for each UAV; Finally, to cope with the instability of CSCM results, two strategies of employing genetic algorithm are studied. Simulation results show that the CSCM-SA algorithm is effective to conduct task assignments for the large-scale multi-UAV systems.
