  • Publication number: 20220266450
    Abstract: A control method of a gimbal includes in response to the gimbal being in a sleeping mode and receiving a push-pull operation on a frame of the gimbal, obtaining a current target joint angle according to an actual joint angle of a motor arranged at the frame and configured to rotate the frame and controlling the motor according to the current target joint angle. The actual joint angle corresponds to a position where the push-pull operation reaches.

  • Publication number: 20220166910
    Abstract: A gimbal control method, a gimbal and a computer-readable storage medium including the gimbal control method are provided. The gimbal control method may include determining a target attitude angle of a gimbal, determining an attitude deviation value of the gimbal based on the target attitude angle and a current attitude angle of a clamping portion of the gimbal, generating a corresponding centering control instruction based upon the attitude deviation value, and executing the centering control instruction to control the gimbal to return to a center position.

  • Publication number: 20220163166
    Abstract: The present disclosure provides a handheld gimbal that includes a handle part, a first bracket, a second bracket, a third bracket, a first motor, a second motor, and a third motor. The handheld gimbal includes a plurality of use modes corresponding to a plurality of attitudes of the first bracket. When the handle part is substantially in a vertical state, the handle part is tilted counterclockwise or clockwise to rotate the handle part around a roll axis, and the first motor follows the handle part to rotate to drive the first bracket to rotate around the roll axis. When the handle part is substantially in a horizontal state, the handle part is tilted counterclockwise or clockwise to rotate the handle part around a yaw axis, and the first motor follows the handle part to rotate to drive the first bracket to rotate around the yaw axis.

  • Publication number: 20220163874
    Abstract: A gimbal control method, a gimbal, and a computer-readable storage medium are provided. The method includes: determining a target motor to be rotated and a target joint angle; generating a corresponding rotation control instruction based on a deviation between a current joint angle of the target motor and the target joint angle; and controlling the target motor to rotate based on the rotation control instruction. This disclosure improves convenience of switching between a horizontal shooting mode and a vertical shooting mode.

  • Patent number: 11265471
    Abstract: The present disclosure provides a gimbal control method, a device, a gimbal, a system, and a storage medium. The gimbal includes at least one axis of rotation. The method includes: determining a current first working mode of the gimbal; and if the gimbal satisfies a preset mode switching condition, controlling the gimbal to switch from the first working mode to a second working mode, and enabling the gimbal to maintain smooth and stable operation during the switching process, where in the first working mode, the axis of rotation is configured to enable the gimbal to face a first direction, and in the second working mode, the axis of rotation is configured to enable the gimbal to face a second direction. In this way, smooth transition of the gimbal can be maintained during mode switching, so that stability of image shooting during mode switching of the gimbal is improved.
