[0002] Unmanned plane is a kind of not carrying person aircraft that is manipulated using radio remote control equipment or self-provided program control device. They can complete task autonomously or according to pre-set program without the direct operation of pilot. Unmanned plane has the characteristics of high flexibility, strong portability, easy operation, etc., and is widely used in agriculture, environmental protection, construction, transportation and medical treatment and other fields.

[0003] In the Chinese utility model patent with publication No. CN217396830U, a kind of unmanned plane with wind-preventing mechanism for surveying and mapping is disclosed, including unmanned plane body, the unmanned plane body is installed with multiple rotors, the front end of unmanned plane body is installed with camera, the outside of camera is provided with perspective wind shield.
