Problems solved by technology

[0004] However, most of the existing work uses swarm intelligence algorithms and does not attempt to solve such problems from the perspective of deterministic optimization algorithms
Swarm intelligence algorithm is different from deterministic optimization algorithms such as linear programming and convex optimization, but a probabilistic optimization algorithm. Although it can find the solution to the problem in some cases, it has a weak theoretical foundation, uncertain optimization results, Unable to prove convergence and other shortcomings, greatly restricting the application of the algorithm

Abstract

The invention discloses an unmanned aerial vehicle flight path distribution method and device. Through an improved path distribution algorithm based on a basic idea of a branch and bound method, the min-max integer planning problem of path distribution is solved; and then through an optimized solution, optimal flight paths corresponding to all unmanned aerial vehicles are obtained and distributedto finish a flight task. The unmanned aerial vehicle flight path distribution method and device can help a user to solve the problems in ensuring the parallel flight time of the multiple unmanned aerial vehicles to be shortest and realizing the optimal path distribution on the premise that the unmanned aerial vehicles finish the flight task and meet the constraint conditions.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle control, and in particular relates to a method and a device for allocating flight paths of an unmanned aerial vehicle. Background technique [0002] With the rapid development of high and new technologies such as digital communication technology, automatic control technology, artificial intelligence technology, and the urgent needs of civil fields such as aerial photography and surveying and military fields such as reconnaissance and strike in modern warfare, the related research and application of UAVs have entered the A stage of rapid development. However, under the constraints of the complex environment of six-dimensional integration of "land, sea, air, space, electricity, and network", a single UAV often restricts the optimization of tasks due to lack of real-time, completeness, and reliability. As a result, the task cannot be completed as soon as possible within the specified...
