Method and apparatus for navigating unmanned aerial vehicle
First Claim
1. A method for navigating an unmanned aerial vehicle (UAV) from an initial position of the UAV towards a base position, comprising:
- A) flying the UAV to a plurality of destination positions each having a first predetermined distance from the initial position of the UAV, wherein the plurality of destination positions correspond to a plurality of trial directions with respect to the initial position, respectively;
B) detecting, for each of the plurality of destination positions, a distance from the base position to the destination position when the UAV is at the destination position, thereby to obtain a plurality of detected distances corresponding to the plurality of trial directions, respectively;
C) determining a return direction of the UAV on the basis of the plurality of detected distances, wherein the return direction is substantially directed towards the base position; and
D) flying the UAV a second predetermined distance along the return direction such that the UAV is relatively closer to the base position.
