Abstract

A method for adjusting a flight direction of an unmanned aerial vehicle (UAV) using a control device receives a first direction of the control device and a control command of the UAV, obtains a second direction of the UAV, and calculates an angle deviation between the first direction and the second direction. The method further adjusts the control command of the UAV according to the angle deviation to obtain an adjusted control command, and controls a flight direction of the UAV according to the adjusted control command

Claims

1. A method for adjusting a flight direction of an unmanned aerial vehicle using a control device, the method comprising:

receiving a first direction of the control device and a control command of the unmanned aerial vehicle (UAV);

obtaining a second direction of the UAV using an electronic compass chip of the UAV;

calculating an angle deviation between the first direction of the control device and the second direction of the UAV;

adjusting the control command of the UAV according to the angle deviation, and obtaining an adjusted control command; and

controlling a flight direction of the UAV according to the adjusted control command

2. The method according to claim 1, wherein the first direction of the control device comprises a first cardinal direction, a first deflecting direction, and a first deflecting angle of the control device.

3. The method according to claim 1, wherein the second direction of the UAV comprises a second cardinal direction, a second deflecting direction, and a second deflecting angle of the UAV.

4. The method according to claim 1, wherein the step of adjusting the control command of the UAV according to the angle deviation comprises:

adjusting the second direction of the UAV to the first direction of the control device according to the angle deviation between the first direction and the second direction.

5. An unmanned aerial vehicle (UAV) in communication with a control device, comprising:

a storage device;

an electronic compass chip;

at least one processor; and

one or more modules that are stored in the storage device and are executed by the at least one processor, the one or more modules comprising instructions;

to receive a first direction of the control device and a control command of the unmanned aerial vehicle (UAV);

to obtain a second direction of the UAV using an electronic compass chip of the UAV;

to calculate an angle deviation between the first direction of the control device and the second direction of the UAV;

to adjust the control command of the UAV according to the angle deviation, and obtain an adjusted control command; and

to control a flight direction of the UAV according to the adjusted control command.

6. The UAV according to claim 5, wherein the first direction of the control device comprises a first cardinal direction, a first deflecting direction, and a first deflecting angle of the control device.

7. The UAV according to claim 5, wherein the second direction of the UAV comprises a second cardinal direction, a second deflecting direction, and a second deflecting angle of the UAV.

8. The UAV according to claim 5, wherein the instruction of adjusting the control command of the UAV according to the angle deviation comprises:

adjusting the second direction of the UAV to the first direction of the control device according to the angle deviation between the first direction and the second direction.

9. A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an unmanned aerial vehicle, causes the processor to perform a method for adjusting a flight direction of the unmanned aerial vehicle using a control device, the method comprising:

receiving a first direction of the control device and a control command of the unmanned aerial vehicle (UAV);

obtaining a second direction of the UAV using an electronic compass chip of the UAV;

calculating an angle deviation between the first direction of the control device and the second direction of the UAV;
