Abstract

The present disclosure provides a handheld gimbal control method and a handheld gimbal. The method includes: acquiring an input signal (S 301 ); and performing a first control operation triggered by a first trigger signal in response to the input signal being a predetermined first trigger signal, where the first control operation is used to control the yaw axis motor disposed on the handheld gimbal to start and continue to work so as to enable the imaging device carried by the handheld gimbal to start and continue a rolling rotation (S 302 ). The control method relieves a user from pressing the control button on the handle at all times, thereby improving the flexibility of user operation and user experience.

First claim

What is claimed is:

1. A method for controlling a handheld gimbal comprising: obtaining an input signal; performing a first control operation triggered by a first trigger signal in response to the input signal being a predetermined first trigger signal, wherein the first control operation is used to control a yaw axis motor disposed on the handheld gimbal to start and continue to work as to enable an imaging device carried by the handheld gimbal to start and continue a rolling rotation; and performing a second control operation triggered by a second trigger signal in response to obtaining a second predetermined trigger signal when the imaging device performs the continuous rolling rotation, wherein the second control operation includes: in response to the second predetermined trigger signal, detecting whether a roll angle of the imaging device is equal to a preset value; in response to detecting that the roll angle of the imaging device is not equal to the preset value, controlling the yaw axis motor to continue to work; and in response to detecting that the roll angle of the imaging device is equal to the preset value, controlling the yaw axis motor to stop working to cause the imaging device to stop the continuous rolling rotation.

2. The method of claim 1 , wherein before performing the first control operation triggered by the first trigger signal, further includes:
determining whether at least one of a roll angle of a handle of the handheld gimbal and a roll angle of the imaging device is approximately 0°; and
performing the first control operation in response to at least one of the roll angle of the handle and the roll angle of the imaging device being approximately 0°.

3. The method of claim 1 , wherein before performing the first control operation triggered by the first trigger signal, further includes:
determining whether at least one of a pitch angle and a yaw angle of the imaging device is approximately 0°; and
performing the first control operation in response to at least one of the pitch angle and the yaw angle of the imaging device being approximately 0°.

4. The method of claim 1 , wherein obtaining the input signal includes:
obtaining an operation direction and a control amount of a rocker in response to detecting a user performing a trigger operation on the rocker disposed on the handheld gimbal; and
generating the input signal based on the operation direction and the control amount.

5. The method of claim 4 , wherein the input signal is an edge signal, and generating the input signal based on the operation direction and the control amount includes:
determining whether the input signal is a rising edge signal or a falling edge signal based on the operation direction; and
determining a starting point and an ending point of an amplitude change of the input signal at a rising edge or a falling edge based on the control amount.

6. The method of claim 1 , wherein performing the first control operation triggered by the first trigger signal includes:
determining the first control operation triggered by the first trigger signal based on a predetermined correspondence between the first trigger signal and the first control operation; and
performing the first control operation.

7. The method of claim 6 , wherein the first control operation includes at least one of:
controlling the yaw axis motor to start and continue to work to cause the imaging device to start and continue the rolling rotation in a clockwise direction;
controlling the yaw axis motor to start and continue to work to cause the imaging device to start and continue the rolling rotation in a counterclockwise direction;
controlling the yaw axis motor to start and continue to work to cause the imaging device to start and continue the rolling rotation in a clockwise direction, and controlling the yaw axis motor to stop working when a rotation angle reaches a first predetermined angle;
controlling the yaw axis motor to start and continue to work to cause the imaging device to start and continue the rolling rotation in a counterclockwise direction, and controlling the yaw axis motor to stop working when the rotation angle reaches a second predetermined angle;
controlling the yaw axis motor to start and continue to work to cause the imaging device to start and continue the rolling rotation in a clockwise direction, controlling the yaw axis motor to continue to work when the rotation angle reaches a third predetermined angle, and controlling the yaw axis motor to stop working when the roll angle of the imaging device is approximately 0°; or
controlling the yaw axis motor to start and continue to work to cause the imaging device to start and continue the rolling rotation in a counterclockwise direction, controlling the yaw axis motor to continue to work when the rotation angle reaches a fourth predetermined angle, and controlling the yaw axis motor to stop working when the roll angle of the imaging device is approximately 0°.

8. The method of claim 7 , wherein:
at least one of the first predetermined angle, the second predetermined angle, the third predetermined angle, or the fourth predetermined angle is 360°.

9. The method of claim 1 , wherein:
obtaining the input signal includes:
obtaining a first electrical signal and a second electrical signal generated in response to detecting two consecutive user inputs; and

performing the first control operation triggered by the first trigger signal in response to the input signal being the predetermined first trigger signal includes:
performing the first control operation in response to the triggering of the first electrical signal and the second electrical signal being determined to be successful.

10. The method of claim 9 , wherein the two consecutive user inputs includes a user moving a rocker in a direction for two consecutive times.

11. The method of claim 9 , wherein obtaining the input signal further includes:
determining triggering of the second electrical signal to be successful in response to at least one of:
an amplitude of the second electrical signal being greater than or equal to a specific proportion of an amplitude of the first electrical signal,
a response time of a signal edge change of the second electrical signal being less than a first predetermined duration, or
a time interval between the first electrical signal and the second electrical signal being less than a second predetermined duration.

12. The method of claim 1 , wherein the input signal is an edge signal, and obtaining the input signal includes:
obtaining an operation direction and a control amount of a rocker in response to detecting a user performing a trigger operation on the rocker disposed on the handheld gimbal, obtaining the control amount of the rocker including:
obtaining a starting value and an ending value of the control amount based on an initial position and an ending position of the rocker in the operation direction; and
generating the input signal based on the operation direction and the control amount, including:
determining whether the input signal is a rising edge signal or a falling edge signal based on the operation direction; and
determining the starting point and the ending point of the amplitude change of the input signal at the rising edge or the falling edge, respectively, based on the starting value and the ending value of the control amount.

13. A handheld gimbal comprising:
a gimbal including a gimbal base and a plurality of axis joints, each of the axis joints including a motor and an axis arm drivingly connected to the motor;
a handle connected to the gimbal base;
an imaging device carried by the gim
