未知混动态环境下多无人机轨迹规划
Trajectory planning for multi-drone in unknow mixed dynamic environments
摘要
Abstract
The realization of fast online replanning for multi-drone in an unknown mixed dynamic environment poses a significant challenge.This paper proposes a decentralized kinodynamic planning scheme to rapidly replan dynamically feasible trajectories for autonomous drones in mixed dynamic environments with static and dynamic obstacles.Firstly,we introduce an improved kinodynamic path search method that addresses the limitations of dealing with dynamic obstacles and low search efficiency.This is achieved by incorporating the optimal reciprocal collision avoidance al-gorithm,resulting in a safe reference path.Then,an initial trajectory is fitted according to the reference path and optim-ized using a gradient-based optimization method.To enhance optimization efficiency,a gradient construction method is proposed,adapting kinodynamic planning schemes.This method efficiently utilizes known information to rapidly con-struct obstacle avoidance gradients,enabling trajectory optimization to be completed within a few milliseconds.Finally,the feasibility and efficiency of the proposed approach were validated through comparison with other planning schemes.关键词
