Research Progress on UAV Trajectory Planning Algorithm
At present,the development of UAV technology has made obvious breakthroughs,and the application fields of UAV have expanded from military to commerce,scientific research,entertainment and other fields.This paper takes the UAV trajectory planning algorithm as the research object.Firstly,according to the principle and characteristics of the trajectory planning algorithm,this paper divides it into two categories of global planning algorithm and local planning algorithm,among which the global planning algorithm can be divided into the graph search algorithm and intelligent bionic algorithm.Secondly,the principles,workflow,advantages and disadvantages of the algorithms are analyzed in depth,the corresponding improvement methods are introduced,and their applications in the corresponding fields are elaborated in combination with the characteristics of the algorithms.Finally,it discusses the limitations and challenges of the above algorithms in the practical application,looks forward to the development trend of the future trajectory planning technology,and points out the direction for the research of UAV trajectory planning algorithm.
