Abstract: A UAV (unmanned aerial vehicle) arm mechanism includes an arm fixed device, a control device, a limiting device, and an arm connecting device, wherein the control device is adapted for controlling an assembly and disassembly of the arm fixed device and the arm connecting device, the limiting device is adapted for relatively fixing the arm fixed device and the arm connecting device; the control device is adapted for driving the limiting device to be detached from the arm connecting device, so as to achieve that the arm fixed device and the arm connecting device switch among at least three different states through a relative rotation. The UAV and the UAV arm mechanism can be locked up through the positioning pins, and also can be folded and disassembled after pressing the controlling device.

Abstract: The present disclosure relates to an aerial shooting method and system using a drone, wherein the aerial shooting method using a drone comprises steps of presetting an aerial path and generating a first operation instruction based on the preset aerial path; controlling the drone to fly along the preset aerial path according to the first operation instruction; marking a plurality of waypoints during the flight of the drone along the preset aerial path; planning a flight path based on the plurality of waypoints and generating a flight instruction based on the flight path; making the drone automatically fly along the flight path according to the flight instruction; and controlling the drone to shoot during the automatic flight of the drone.

Abstract: A target tracking method for an air vehicle includes steps of: during a flight of an air vehicle main body to a position corresponding to a global positioning system (GPS) positioning signal, taking pictures of an area where a reference target is located by a camera, and obtaining a reference image; extracting reference image characteristics of the reference target and initial position information of the reference target in the reference image from the reference image; when the camera obtains a temporary image showing a temporary target, extracting temporary image characteristics of the temporary target and temporary position information of the temporary target in the temporary image from the temporary image; if the reference image characteristics are consistent with the temporary image characteristics, calculating a deviation direction according to a difference between the initial position information and the temporary position information; and tracking the temporary target in the deviation direction.

Abstract: This invention discloses a pan-tilt hand holder which features that: It includes a clamping mechanism for holding the mobile terminal, a control device, and a power device are provided, wherein, the frame body is configured to install a pan-tilt, the control device is configured to control the movement of the pan-tilt, and the power device is configured to supply electric power to the control device. The application of the invention achieves not only the handheld movement operation of the pan-tilt, but also the operation with just one hand, which is convenient for use.

Abstract: A pan-tilt and an aerial camera containing a pan-tilt. This pan-tilt includes a motor which has a first part and a second part of relative movement, a slip ring which is installed in the motor and has a fixing part and a rotating part, and a control part which is installed under the motor and at which the second part is installed. The center of the motor has a first hole which longitudinally penetrates through, in which the slip ring is installed. The fixing part is static relative to the first part. The control part is electrically connected to the rotating part via a wire which is set to pass through the first hole. The control part is electrically connected with the motor. The pan-tilt can be rotated by 360 degrees.
