A camera gimbal is provided having first and second arms, a support connected to the second arm and having an upper end to which a camera may be mounted and a lower end to which a counterweight is connected, and a gearbox including a gear and a rotary damper. The second arm is rotatable relative to the first arm and includes a proximal end portion forming a housing for the gearbox and a distal end portion to which the support is connected. The camera gimbal is purely-mechanical in operation and is without connection to a power source relying solely on gravity acting on a camera mounted on the support and the counterweight to cause rotation of the first arm relative to the second arm to maintain the camera in a relatively level position while the rotary damper damps the rotational movement.

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.

An equatorial mount having a base, a right ascension base, a right ascension shaft, a declination base, a declination shaft, and a mount-rotation mechanism, the declination base rotatable about a right ascension axis relative to the right ascension base, and the declination shaft rotatable about a declination axis relative to the declination axis, wherein the mount-rotation mechanism is engageable and disenagageable from one or the other of the right ascension shaft and the declination shaft, to apply torque between the declination base and that shaft when engaged and to permit relative rotation of the shaft and the declination base when disengaged.

A translation axis assembly includes a supporting arm, a connecting plate configured to be movably mounted to the supporting arm, and a center-of-gravity adjusting device connected between the supporting arm and the connecting plate. The center-of-gravity adjusting device is configured to adjust a center of gravity of the translation axis assembly by adjusting a position of the supporting arm on the connecting plate. The center-of-gravity adjusting device includes a lead screw and a moving member rotatably and movably arranged on the lead screw. The moving member is received by the connecting plate and is fixedly connected to the supporting arm. The moving member includes a threaded hole in a threaded connection with the lead screw.

A method for object tracking. The method includes capturing a sequence of images of a scene, detecting, by a hardware processor, based on a pattern of local light change across the sequence of images, a reflective light source in the scene, comparing, by the hardware processor in response to detecting the reflective light source, a location of the reflective light source in at least one image of the sequence of images and a target position within the at least one image to generate a result, and generating, by the hardware processor based on the result, a control signal for changing a field-of-view of a camera device such that the reflective light source substantially aligns with the target position within the field-of-view, wherein the reflective light source emits an object-reflected light.

Proposed is an image photographing-assisting accessory of an electronic device, which corrects shaking of an electronic device, the accessory comprising: a coupling unit to which the electronic device is coupled; a plurality of link rods connected to the coupling unit and rotatably coupled to each other; and a correcting unit formed at a part to which the link rods are rotatably coupled, wherein the correcting unit includes a fixing unit, a rotating unit rotating about the fixing unit, and a rotation locking unit for restraining the rotation of the rotating unit. Other embodiments are also possible.

A method of controlling a gimbal may comprise obtaining a capturing position of a target object in a captured image, the capturing position being determined by means of an image capturer, the image capturer being a camera having a manual lens or an automatic lens, and the image capturer being communicatively connected to the gimbal; determining, based on the capturing position, control parameters for a following operation on the target object; and controlling the gimbal according to the control parameters to achieve the following operation of the target object.

A method includes fabricating a mirror system that includes a dual axis gimbal, a mirror, and a mirror substrate that are formed together as an integral component using an additive manufacturing process. The method also includes forming multiple first gaps in the mirror system using a subtractive manufacturing process, where the first gaps extend through the mirror system in a first direction. The method further includes forming multiple second gaps in the mirror system using the subtractive manufacturing process, where the second gaps extend through the mirror system in a second direction perpendicular to the first direction. The first gaps and the second gaps separate the gimbal into a top portion and a bottom portion.

A gimbal for carrying an imaging device includes a support frame and a center of gravity adjusting unit. The center of gravity adjusting unit includes a transmission member and a coupling member. The center of gravity adjusting unit is coupled to the support frame through the coupling member. A motor is configured to enable the transmission member to drive a portion of the support frame to have a linear movement relative to the coupling member to adjust a center of gravity of the support frame.

A gimbal load mounting assembly includes a first seating body, a second seating body configured to slidably connect with the first seating body, and a fastener. The first seating body is configured to connect with a gimbal frame and slide in a first direction. The second seating body is configured to mount a load and is slidable on the first seating body in a second direction. The fastener is configured to connect with the first seating body and to lock a mounting location of the first seating body relative to the gimbal frame and a mounting location of the second seating body relative to the first seating body.
