The operation environment of the unmanned aerial vehicle is deepened from a 2D plane to a 3D space, so that the flight path of the unmanned aerial vehicle better conforms to the actual situation; according to the method, the constraint of the movement distance and the constraint of the space coordinate movement are converted, the scheme for solving the original traversal problem is successively optimized, the complexity is greatly reduced, and the computing resources and the computing time are saved. According to the invention, the calculation complexity is reduced, and the operation resources of the processor are saved, so that the trajectory of the unmanned aerial vehicle in the three-dimensional space is optimized.
