Abstract

The invention relates to an unmanned aerial vehicle route planning method based on a sparrow search algorithm, and the method comprises the steps: (1) carrying out the modeling of the route planning of an unmanned aerial vehicle, and obtaining a total cost function; step (2), optimizing the total cost function through a sparrow search algorithm; and step (3), obtaining an optimal path for unmanned aerial vehicle flight path planning. According to the invention, the optimal path of the flight path of the unmanned aerial vehicle can be found through a sparrow search algorithm.

Description

technical field [0001] The invention relates to the technical field of UAV track planning, in particular to a UAV track planning method based on a sparrow search algorithm. Background technique [0002] UAVs often need to perform complex tasks in the air and will be deployed in areas where manual operation is difficult for special operations, such as surveillance, airdrops, etc. When the UAV enters a complex environment, humans must make reasonable and effective planning of its flight trajectory before manipulating the UAV to perform specified tasks. Only after obtaining a reference trajectory can the UAV follow this It is very important to have a good trajectory planning when performing complex tasks. Three-dimensional path planning can be defined as an NP problem, and its main purpose is to optimize the path between the starting point and the target point. In this process, multiple constraints need to be dealt with, such as the UAV's own performance constraints, threat c...
