s300: the edge processor determining whether at least one target object is identified from the image data;
if yes, go to step S400;
otherwise, returning to the step S200;
s400: the edge processor judges whether the resolution of the miniature image sensor in the current starting state is the highest level or not, and if so, the identification result is broadcasted through a broadcast antenna;
if not, the current micro image sensor in the starting state is closed, the next high-level micro image sensor is started, and the step S200 is returned;
s500: and other edge processors change the flight track of the edge processors after receiving the identification result broadcasted by the broadcasting antenna.
More specifically, the identification result in step S400 includes identifying the current position of the controllable aircraft of at least one target object;
