A method for controlling an attitude of a payload includes determining an input torque based on an input angle and one or more motion characteristics of the payload, determining an estimated disturbance torque based on one or more motion characteristics of a carrier to which the payload is coupled, and calculating an output torque based on the input torque and the estimated disturbance torque. The output torque is configured to effect movement of the carrier to achieve a desired attitude of the payload.

A method includes one or more processors of a payload releasably coupled to a carrier detecting a deviation of a target from an expected target position within an image captured by an image sensor of the payload, and generating one or more control signals for the carrier based at least in part on the detected deviation of the target. The one or more control signals cause the carrier to change a pose of the payload so as to reduce the detected deviation in a subsequent image captured by the image sensor.

A method to stabilize a camera device. The method includes receiving, from the camera device mounted in a camera device holder, sensor data representing at least one selected from a group consisting of orientation and movement of the camera device, generating, using a pre-determined algorithm, a control signal based on the sensor data, and adjusting, using the control signal, a geometrical behavior of the camera device holder, wherein the geometrical behavior corresponds to at least one selected from a group consisting of the orientation and the movement of the camera device holder.

A gimbal control method includes obtaining a target attitude parameter of a target attitude of an active gimbal and transmitting the target attitude parameter to a follower gimbal to adjust the follower gimbal to the target attitude. The target attitude is an attitude that the active gimbal is moving to.

The present disclosure provides a handheld gimbal control method and a handheld gimbal. The method includes: acquiring an input signal (S301); 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 (S302). 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.

A gimbal includes a pitch axis assembly including a pitch axis motor and configured to be connected to a payload, a roll axis assembly connected to the pitch axis and including a roll axis motor positioned below the pitch axis motor, and a yaw axis assembly connected to the roll axis assembly and including a yaw axis motor positioned below the roll axis motor. The roll axis motor and the yaw axis assembly are configured to be positioned below the payload.

A method for detecting a payload on a carrier configured to support the payload includes obtaining a obtaining at least one motion characteristic of the carrier. The at least one motion characteristic is indicative of a coupling state between the carrier and the payload. The method further includes assessing the coupling state between the carrier and the payload based on the at least one motion characteristic. Assessing the coupling state between the carrier and the payload includes at least one of assessing whether the payload is coupled to the carrier or assessing whether the payload is correctly mounted at the carrier.

A gimbal sleeve for connecting to a camera gimbal may float between a floor surface and a ceiling surface of an aerial vehicle chassis such that the gimbal sleeve has freedom of motion in yaw, pitch, and roll directions relative to the vehicle chassis. The gimbal sleeve may comprise a pair of connection points to the lower dampers on a floor surface of the vehicle chassis. The gimbal sleeve may furthermore comprise a ball joint coupled to a back surface of the vehicle chassis. The connection points include spring forces that enable the gimbal sleeve to return to an equilibrium position in response to external vibrations and reduce the magnitude of vibrations transferred from the aerial vehicle to the gimbal and camera systems.

Disclosed is an electronic motor with two bearings. The motor is structured so that, when loaded, the majority of the load (e.g., a radial load) is borne by one of the bearings. The bearing that bears a greater load may be larger and, thus, better suited for a heavy load. In some embodiments, the larger bearing may include rolling elements that have respective radii larger than respective radii of rolling elements of the other bearing by a ratio of at least 1.5 (150%). In some embodiments, the larger bearing may have an outer race with a radius that is greater than a radius of the outer race of the smaller bearing by a ratio of at least 1.5. In some embodiments, the motors may include a third bearing between the two bearings. The third bearing may reduce vibration in the motor.

A photographing device includes a housing, a fill light mounted at the housing, and a lens module mounted in the housing. Relative position and attitude of the fill light relative to the lens module are fixed. An optical axis of the fill light is approximately parallel to an optical axis of the lens module. The lens module and the fill light rotate together with the housing.
