Cooperative hunting method for unmanned aerial vehicle group in three-dimensional unknown complex environment

The invention discloses an unmanned aerial vehicle group cooperative hunting method in a three-dimensional unknown complex environment, and the method comprises the steps: S1, building an unmanned aerial vehicle group model which comprises an unmanned aerial vehicle group system obstacle avoidance model and is built based on an expansion principle; s2, building a hunting algorithm: S21, building a three-dimensional simplified virtual stress hunting model, S22, calculating the magnitude and speed of resultant force borne by unmanned aerial vehicle individuals based on the three-dimensional simplified virtual stress hunting model and an unmanned aerial vehicle group system obstacle avoidance model, S23, calculating the expected speed and angle of the unmanned aerial vehicle individuals, updating the positions of the individuals according to a time step length, and obtaining the hunting algorithm; and S24, judging whether each unmanned aerial vehicle arrives at the surrounding circumference and is uniformly dist
