Low-altitude inspection flight three-dimensional path optimization method

The invention discloses a low-altitude inspection flight three-dimensional path optimization method. The method comprises the steps of obtaining a starting point and an end point of an aircraft and astarting point and an end point of each high-voltage line; determining the number of genetic populations based on a genetic algorithm, and initializing the genetic populations by adopting a random path generation method to obtain a flight path; selecting a part of flight paths by adopting a random number generator to perform high-voltage line crossover operation to obtain a crossover population; replacing the flight path with low fitness in the genetic population with the flight path in the cross population; removing the flight path with the highest fitness in the genetic population and the flight path replaced by the cross population to obtain a remaining flight path, and performing mutation operation of high-voltage line reverse order and high-voltage line exchange for the remaining flight path; and repeating th
