Abstract

A method for controlling a gimbal configured to carry a load includes detecting a motion state of a motion of the gimbal or the load, comparing the motion state to a preset threshold to obtain a comparison result, and controlling the gimbal to maintain the load in an original posture based on the comparison result.

First claim

What is claimed is:

1. A method for controlling a gimbal configured to carry a load, the method comprising:
detecting a motion state of a motion of the gimbal or the load;
comparing the motion state to a preset threshold to obtain a comparison result; and
controlling the gimbal to maintain the load in an original posture based on the comparison result.

2. The method of claim 1 , wherein the comparison result indicates that the motion state does not exceed the preset threshold.

3. The method of claim 1 , further comprising:
controlling the gimbal to move along a moving direction of the motion when the comparison result indicates that the motion state exceeds the preset threshold.

4. The method of claim 1 , wherein controlling the gimbal to maintain the load in the original posture comprises:
controlling the gimbal such that the gimbal does not move along a moving direction of the motion.

5. The method of claim 1 , further comprising:
determining whether the detected motion state corresponds to a received control signal to obtain a determination result; and
controlling the gimbal based on the determination result.

6. The method of claim 1 , wherein the motion state comprises an angular velocity and the preset threshold is an angular velocity threshold.

7. The method of claim 1 , wherein the motion state comprises a rotation angle and the present threshold is a rotation angle threshold.

8. The method of claim 1 , wherein the load is a camera.

9. The method of claim 1 , wherein the gimbal is configured to be handheld.

10. The method of claim 1 , wherein the gimbal is mounted on a moving object.

11. A system for controlling a gimbal configured to carry a load, the system comprising:
a sensor that operates to detect a motion state of a motion of the gimbal or the load; and
a controller that operates to:
compare the motion state to a preset threshold to obtain a comparison result; and
control the gimbal to maintain the load in an original posture based on the comparison result.

12. The system of claim 11 , wherein the comparison result indicates that the motion state does not exceed the preset threshold.

13. The system of claim 11 , wherein the controller further operates to:
control the gimbal to move along a moving direction of the motion when the comparison result indicates that the motion state exceeds the preset threshold.

14. The system of claim 11 , wherein in controlling the gimbal to maintain the load in the original posture, the controller further operates to:
control the gimbal such that the gimbal does not move along a moving direction of the motion.

15. The system of claim 11 , wherein the motion state comprises an angular velocity and the preset threshold is an angular velocity threshold, or wherein the motion state comprises a rotation angle and the preset threshold is a rotation angle threshold.

16. A system, comprising:
a gimbal mounted on a moving object, the gimbal being configured to carry a load; and
a controller that operates to:
detect a motion state of a motion of the gimbal or the load;
compare the motion state to a preset threshold to obtain a comparison result; and
control the gimbal to maintain the load in an original posture based on the comparison result.

17. The system of claim 16 , wherein the comparison result indicates that the motion state does not exceed the preset threshold.

18. The system of claim 16 , wherein the controller further operates to:
control the gimbal to move along a moving direction of the motion when the comparison result indicates that the motion state exceeds the preset threshold.

19. The system of claim 16 , wherein in controlling the gimbal to maintain the load in the original posture, the controller further operates to:
control the gimbal such that the gimbal does not move along a moving direction of the motion.

20. The system of claim 16 , wherein the moving object is an aircraft, a vehicle, or an unmanned aerial vehicle.
