Technical Field

Background

This disclosure provides background information only with respect to embodiments and does not constitute prior art.

Recently, the use of small unmanned aircraft, such as drones, has increased. When aerial photography is performed using a camera mounted on a small unmanned aerial vehicle, there are advantages in convenience and low cost compared to the case of using a passenger helicopter or the like.

In the case of mounting the camera on the aircraft, since the aircraft may perform three-dimensional rotation at an angle during flight, a three-axis rotation device may be used to prevent the camera from being affected by three-axis rotation.

The three-axis rotating apparatus compensates for the three-axis rotation of the aircraft, and therefore, the camera mounted on the aircraft can be prevented from being affected by the three-axis rotation of the aircraft.

The three-axis rotating apparatus may be used in a state where the three-axis rotating apparatus is mounted on an aircraft and a camera is mounted on the three-axis rotating apparatus. For this reason, it is important that the three-axis rotating apparatus must have a small and light structure while having a camera attitude maintaining performance.
