In these applications, the camera carried by the drone plays a vital role. It is responsible for capturing high-definition and stable images, providing strong support for subsequent data processing and analysis. However, drones are affected by various factors during flight, such as wind shear, turbulence, mechanical vibration, etc. These factors can cause the drone to have unstable jitters, which in turn affects the imaging quality of the camera. In order to solve this problem, researchers have proposed a variety of camera stabilization technologies, such as mechanical stabilization, electronic stabilization, optical stabilization, etc. However, these technologies have more or less some limitations, such as heavy weight, high cost, and limited stabilization effect.
