[0077] In the embodiment, the support frames are all used for supporting after the unmanned aerial vehicle takes off and lands.

[0078] The specific use process of the unmanned aerial vehicle is as follows:

[0079] First, for the UAV take-off phase: the take-off phase of the UAV is the key beginning of the whole flight process; based on its unique flight structure, a series of delicate operations need to be carried out in this phase to ensure safe and smooth take-off, first, when the UAV is ready to take off, all the motors need to be tested to the maximum limit to ensure that the best effect can be achieved during flight, and the pod is rotated to be horizontal and perpendicular to the ground; This adjustment is to avoid the camera lens touching the ground during take-off, thereby preventing damage to the expensive and delicate camera lens inside the UAV pod;

[0080] When the UAV starts to take off, the pod, i.e. the camera lens, will need to be adjusted in position according to the gyroscope inside it. By analyzing the data collected by the gyroscope, the angle deviation is determined and corrected by rotating the motor. This process ensures that the UAV pod and the camera lens inside the pod always remain horizontal and perpendicular to the ground, providing a stable image acquisition basis for subsequent flight; When the aircraft is in the horizontal phase, the camera lens direction is parallel to the nose direction, and is in a horizontal and vertical state with the ground; the nose is the end of the first flight wing 11 of the aircraft 1; When the aircraft is in the take-off state, the angle is greater than 45 degrees, the pod can be controlled to control the camera lens to be in a horizontal and central state, and is constantly adjusted according to the current aircraft flight attitude, so that the camera lens is always in a horizontal and central state, thereby ensuring the problem of the camera lens;

[0081] For the UAV flight cruising phase: the flight cruising phase of the UAV is the main phase of its task execution, in this phase, based on its unique flight structure, the camera lens needs to maintain a specific attitude to provide a good field of view; Specifically, the UAV pod lens can always be parallel to the flight direction of the UAV; Such adjustment allows the operator to have a good UAV pod view and clearly observe the terrain, target and potential obstacles in front of the flight;

[0082] When the UAV performs yaw motion, at this time, the flight direction of the UAV changes, and the pod lens also needs to be adjusted accordingly. The gyroscope inside the UAV pod will quickly detect the angle of its deflection and transmit it to the lower host computer or control handle. The operator or the host computer can make real-time manual adjustment or automatic adjustment according to the transmitted data, thereby avoiding excessive deflection that causes image blur or loss of target; The high precision and rapid response capability of the gyroscope enable the pod to adapt to the yaw motion of the UAV in an instant, maintaining stable image acquisition.

[0083] The unmanned aerial vehicle task operation stage: the task operation stage of the unmanned aerial vehicle is the stage where it plays a core role, and in this stage, based on its unique flight structure, the unmanned aerial vehicle and the pod need to be adjusted in a specific way to efficiently complete the task; when the unmanned aerial vehicle enters the task operation stage, its flight state is usually vertical upward flight state; this special flight attitude is to better approach the task target, such as checking high-rise buildings, surveying mountainous terrain, etc.; in this stage, the unmanned aerial vehicle pod can be corrected according to the data obtained by the gyroscope inside it, so that the lens is at a horizontal and vertical angle to the ground, and is perpendicular to the task target; such adjustment enables the unmanned aerial vehicle pod lens to shoot and observe the task target at the best angle, and the horizontal and vertical angle to the ground ensures the stability and accuracy of the image, and the direction perpendicular to the task target enables the operator to more clearly and conveniently perform the task, whether it is to check the details of the building or to accurately survey the terrain, such precise lens adjustment is crucial.

[0084] For the unmanned aerial vehicle landing stage, the landing stage of the unmanned aerial vehicle: when the unmanned aerial vehicle enters the landing stage, the camera lens needs to be rotated to be perpendicular to the ground, the purpose of this is to make the unmanned aerial vehicle camera lens as far away from the ground as possible during the landing process, so as to avoid damage caused by contacting the ground; during the landing process, the height of the unmanned aerial vehicle gradually decreases, and the speed gradually decreases, at this time, the body will be affected by air resistance, ground effect and other factors, the attitude may change, at this time, the attitude data transmitted by the gyroscope can be used to adjust the camera lens, so as to ensure that the camera lens will always maintain a state perpendicular to the ground, when the landing is completed, the unmanned aerial vehicle is stable on the ground, the camera lens can be restored to the state of being horizontal and perpendicular to the ground, this recovery action marks the successful completion of the landing process, and also prepares for the next flight.

[0085] The above is the preferred embodiment of the present application, it should be pointed out that for ordinary skilled in the art, without departing from the principles described in the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
