The invention relates to an unmanned aerial vehicle rotor disturbance correction method and device, and the method comprises the steps: constructing an unmanned aerial vehicle wind speed measurement simulation numerical model based on an environment flight envelope and unmanned aerial vehicle flight parameters; the environment flight envelope is used for setting a mapping relation of flight parameters of the unmanned aerial vehicle in an environment scene; and setting simulation parameters in the unmanned aerial vehicle wind speed simulation numerical model and carrying out a simulation experiment to obtain an estimated quantity of the drainage disturbance influence of the rotation of the unmanned aerial vehicle rotor wing. Fluid simulation under different flight envelope conditions is carried out on an unmanned aerial vehicle wind speed measurement system, the disturbance influence of unmanned aerial vehicle rotors on measurement of an anemograph is estimated according to the difference between a wind speed simulation value at the position of the anemograph and a set value, and an estimated value is obtained and then substituted into an unmanned aerial vehicle motion and attitude compensation algorithm. Therefore, the influence of the disturbance of the rotor wing on the measurement result of the anemograph and the influence caused by the attitude, movement and acceleration of the unmanned aerial vehicle can be corrected, and a more accurate three-dimensional wind speed measurement result can be obtained.
