[0002] Unmanned aircraft, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are completely or intermittently autonomously operated by onboard computers. Surveying and mapping drones are also a type of drone. By installing a surveying and mapping camera at the bottom of the drone and controlling the camera rotation on the surveying and mapping drone through a controller, the surveying and mapping collection work is completed. The surveying and mapping camera is usually exposed at the bottom of the drone. Due to the complex outdoor environment, if the operation is improper and the drone lands unexpectedly, the camera is easily collided and damaged. Utility Model Content
