Claim 10:
11. A direction detecting method, comprising:
detecting a first distance between the first ranging device and a surface of a reflector by a first ranging device of an aerial vehicle, wherein the reflector is a physical reflector;
detecting a second distance between a second ranging device and the surface of the reflector by the second ranging device of the aerial vehicle; and
obtaining an included angle between a direction of a body of the aerial vehicle and the reflector by a controller of the aerial vehicle according to the first distance and the second distance;
wherein the first ranging device has a first signal emission surface, and the second ranging device has a second signal emission surface; a first angle is formed between a first normal direction of the first signal emission surface and a second normal direction of the second signal emission surface, and a second angle is formed between the first normal direction of the first signal emission surface and the direction;
wherein obtaining the included angle between the direction of the body of the aerial vehicle and the reflector by the controller of the aerial vehicle according to the first distance and the second distance comprising:
obtain the included angle between the direction and the reflector according to the first distance, the second distance, the first angle and the second angle, wherein the second distance, the direction of the body and the surface of the reflector form a triangle by the controller.
