High-stability high-precision geographic information surveying and mapping device

The invention discloses a high-stability high-precision geographic information surveying and mapping device, which is provided with a main propeller group mechanism and an auxiliary propeller group mechanism at the same time, can realize balance adjustment of an unmanned aerial vehicle according to the actual vibration amplitude condition, and ensures the stability and stability of the unmanned aerial vehicle during surveying and mapping. Meanwhile, the control condition is improved, when the surveying instrument conducts surveying and mapping, and the fluctuation amplitude is lower than or equal to a set threshold value, the controller only controls the rotating speed of each paddle of the auxiliary propeller set mechanism so that the fluctuation amplitude can be reduced, and the rotating speed of each paddle of the main propeller set mechanism can not be changed; and when the fluctuation amplitude is higher than a set threshold value, the controller adjusts the rotating speed of each paddle of the main prop
