    Abstract: A follow focus device for a gimbal carrying an image capturing device includes a power assembly connected to the image capturing device, a connection member, and an adjustment member electrically connected to the power assembly. The power assembly is configured to adjust at least one lens parameter of the image capturing device. The connection member is configured to fix the power assembly to the gimbal. The adjustment member generates a control signal to adjust the lens parameter of the image capturing device. The power assembly receives the control signal from the adjustment member and, based on the control signal, rotates a part of the image capturing device to adjust the lens parameter of the image capturing device.

    Abstract: A gimbal for supporting a load includes at least three rotatably coupled driving axis assemblies. Each driving axis assembly includes a driving device and a joint arm configured to rotate when driven by the driving device. The gimbal also includes a controller configured to control the gimbal to limit a rotation of at least one of the three driving axis assemblies during a rotation of the gimbal.

    Abstract: Systems, methods, and devices for setting camera parameters are provided. In one aspect, a system for imaging a target object using an imaging device carried by a movable object comprises: one or more sensors configured to detect motion information for the movable object; and one or more processors configured to: receive, from the one or more sensors, the motion information for the movable object; determine, based on the motion information, a change in a spatial relationship between the movable object and the target object; and modify one or more parameters of the imaging device based on the determined change in the spatial relationship between the movable object and the target object such that the imaging device is focused on the target object.
