Research Progress of Metaheuristic Algorithm in Path Planning of Plant Protection UAV
With the continuous development of unmanned system technology,sensor technology and artificial intelligence algorithms and other related technologies,the path planning technology of plant protection UAV is highly valued and widely used in agricultural production.As one of the key technologies of aerial plant protection,plant protection UAV path planning faces a complex and multi-constrained combinatorial optimization problem.Traditional algorithms are often difficult to obtain the desired results,while metaheuristic algorithms become an effective means to solve such optimization problems due to their high efficiency and speed.This paper first introduced path planning in agricultural aviation,and then summarized the key elements of path planning for plant protection UAV and generalized them using a more reasona-ble classification.Next,the metaheuristic algorithms used in related research were classified and sorted out at the algo-rithmic level,and their current status in practical applications was described.The current research results were compre-hensively summarized according to the proposed classification methods and research characteristics.Finally,several feasi-ble development ideas were proposed to address the current problems of plant protection UAV path planning research.
