Abstract: Due to the interference of objective environmental factors at sea, it is difficult to ensure the detection effect
of anti-corrosion state of wind turbine parts. Therefore, the research on anti-corrosion detection method of large-scale
offshore wind turbine parts in high temperature and high humidity environment was proposed. The NC200NW infrared
camera, which integrated an infrared thermal imager and a visible light camera, was used as a monitoring device, and the
timing shooting time interval was set according to the running time and weather conditions of the wind turbine, and the
data acquisition position was marked by GPS positioning function. After removing the noise factor of infrared data of parts
by Gaussian filtering, the pixel value was converted into temperature value based on regional average method, and the
anticorrosion state was determined by extracting the characteristics of temperature gradient and temperature peak. The
test results showed that the proposed method can effectively identify the types of corrosion defects, suppress corrosion
defect signals and accurately locate corrosion defects.Provides reliable guidance for timely maintenance or replacement of
corroded parts.
Key words: infrared thermal imaging; gaussian filtering; regional average method; characteristics of temperature
gradient; characteristics of temperature peak
