Method and apparatus for controlling handheld gimbal, and handheld gimbal
View Patent ↗Provided are a method and apparatus for controlling a handheld gimbal, and a handheld gimbal. The method comprises: receiving an indication, input by a user, of entering a fast following mode; based on the indication of entering the fast following mode, updating control parameters of a camera component in one or more directions, wherein the control parameters of a camera component in one or more directions comprise the maximum following rate and acceleration of the camera component in one or more directions; and applying the updated control parameters of a camera component in one or more directions to control the rotation of one or more corresponding electric motors in a handheld gimbal, thus controlling the movement of the camera component in one or more directions. Where a gimbal handle needs to be rotated quickly for photography, the present invention can enable a camera component fixed on a handheld gimbal to quickly follow a target and perform photography smoothly.
1. A method for controlling a handheld gimbal, comprising:
step 1): receiving an indication to enter a fast following mode input by a user;
step 2): updating, based on the indication to enter the fast following mode, control parameters of a camera component in one or more directions, the control parameters of the camera component in the one or more directions comprising the maximum following rate and acceleration of the camera component in the one or more directions; and
step 3): controlling, by using the updated control parameters of the camera component in the one or more directions, the rotation of one or more corresponding electric motors in the handheld gimbal, so as to control the movement of the camera component in the one or more directions;
wherein the updating control parameters of a camera component in one or more directions comprises: increasing the maximum following rate of the camera component in each of the one or more directions, and increasing the acceleration of the camera component in each of the one or more directions, and
wherein the updated acceleration of the camera component in each of the one or more directions changes with the angle of rotation of the corresponding electric motor.
2. The method according to claim 1 , wherein the control parameters of the camera component in one or more directions further comprise a control dead zone in the one or more directions; and, the updating control parameters of a camera component in one or more directions further comprises: decreasing the control dead zone in each of the one or more directions.
3. The method according to claim 1 , further comprising: recording a previous operating mode of the handheld gimbal prior to updating the control parameters.
4. The method according to claim 3 , after the step 3), further comprising:
receiving an indication to exit the fast following mode input by the user;
updating, based on the recorded previous operating mode, the control parameters of the camera component as control parameters corresponding to the previous operating mode; and
controlling, by using the updated control parameters, the rotation of electric motors in the handheld gimbal, so as to control the movement of the camera component.
5. An apparatus for controlling a handheld gimbal, comprising:
a human-machine interaction unit configured to receive an indication to enter a fast following mode input by a user; and
a control unit configured to update, based on the indication to enter the fast following mode, control parameters of a camera component in one or more directions, and control, by using the updated control parameters of the camera component in the one or more directions, the rotation of one or more corresponding electric motors in the handheld gimbal, so as to control the movement of the camera component in the one or more directions;
wherein the control parameters of the camera component in the one or more directions comprise the maximum following rate and acceleration of the camera component in the one or more directions;
wherein the updating control parameters of a camera component in one or more directions comprises: increasing the maximum following rate of the camera component in each of the one or more directions, and increasing the acceleration of the camera component in each of the one or more directions, and
wherein the updated acceleration of the camera component in each of the one or more directions changes with the angle of rotation of the corresponding electric motor.
6. The apparatus according to claim 5 , wherein the control unit is further configured to record a previous operating mode of the handheld gimbal prior to updating the control parameters.
7. The apparatus according to claim 6 , wherein the human-machine interaction unit is further configured to receive an indication to exit the fast following mode input by the user; and
the control unit is further configured to update, based on the recorded previous operating mode, the control parameters of the camera component as control parameters corresponding to the previous operating mode, and control, by using the updated control parameters, the rotation of electric motors in the handheld gimbal, so as to control the movement of the camera component.
8. The apparatus according to claim 5 , wherein the human-interaction unit is a button arranged on a handle of the handheld gimbal; and
wherein the user inputs the indication to enter the fast following mode by pressing down the button, and inputs the indication to exit the fast following mode by releasing the button.
9. A handheld gimbal, comprising a processor, a memory, a handle and one or more electric motors, wherein the memory stores instructions that can be executed by the processor; and, the instructions, when executed by the processor, cause the handheld gimbal to implement the method according to claim 1 .
