Description

[Technical field]

[0001] The present invention relates to the field of aircraft, and in particular to a gimbal, a camera assembly having the gimbal, and an unmanned aircraft having the camera assembly. [Background technology]

[0002] Unmanned aerial vehicles (UAVs) are a new type of equipment that is developing rapidly. They are flexible, quick to respond, unmanned, and require low operation. UAVs can be equipped with multiple types of sensors or cameras through a gimbal, which can achieve real-time image transmission and high-risk area detection functions. They are a powerful supplement to satellite remote sensing and traditional aerial remote sensing.

[0003] In order to facilitate users to carry, the miniaturization of unmanned aerial vehicles is a development trend. While miniaturization, the functions of unmanned aerial vehicles must also be retained. The gimbal is particularly important as a part of the shooting system of unmanned aerial vehicles.

The general gimbal has three-axis anti-shake, but some very small aircraft can only be equipped with a two-axis anti-shake gimbal.
