Abstract

The invention discloses a fan blade infrared monitoring system and method based on unmanned aerial vehicle inspection, relates to the technical field of image recognition, and solves the problem that in the prior art, an infrared image processing mode of a fan blade is insufficient to adapt to blade temperature changes caused by various environments. According to the method, the infrared thermal images of the fan blades are obtained through the infrared camera carried by the unmanned aerial vehicle, the highest temperature and the lowest temperature of each infrared thermal image are calculated through temperature inversion, then the temperature difference of the fan blades is obtained, and in addition, the multiple infrared thermal images of the fan blade numbers in the same area are obtained; and calculating the highest temperature and the lowest temperature of each infrared thermal image, constructing a temperature analysis set and calculating an overall standard deviation so as to judge the dispersion degree of the temperature in the region, and finally establishing a health evaluation coefficient based on factors such as the temperature difference and the dispersion condition so as to provide quantitative data reference for managers and decision makers. And subsequent management and decision-making work are facilitated.
