Claim 1:
2. The method according to claim 1, wherein obtaining the damage recognition result of the wind turbine blade by performing image recognition on the segmented frequency spectrogram based on the damage recognition model comprises:
calculating a sound spectrum difference factor in response to the impingement of wind on the wind turbine blade based on the segmented frequency spectrogram, wherein the sound spectrum difference factor represents a damage degree of the wind turbine blade; and
obtaining the damage recognition result of the wind turbine blade by performing image recognition on the segmented frequency spectrogram based on the damage recognition model in the case that the sound spectrum difference factor is greater than a difference threshold.
