Abstract

Path planning is the key of UAV autonomous flight. In order to improve the efficiency of UAV path planning in 3D complex environment, an improved path planning algorithm is proposed in this paper. First of all, in terms of map construction, aiming at the problem that sampling points cannot cover narrow free space in the traditional probabilistic roadmaps (PRM), this paper proposes a sampling point translation strategy to move out the sampling points within the obstacle threat. Then, in the aspect of path generation, this paper proposes an improved ant colony optimization (ACO), which improves the transition probability and pheromone update rule of traditional ACO. In order to improve the efficiency of the ACO, target guidance information is added to the calculation of transfer probability. Besides, collision threat cost and path length are added to the pheromone update rule to solve the problem that the traditional ACO can only optimize a single target. The simulation results show that the algorithm in this paper effectively makes up for the shortcomings of the traditional PRM and the traditional ACO. The path planning method in the 3D complex environment of UAV is feasible.
