The embodiment of the invention relates to the field of image processing, and discloses a wind power blade wear analysis method based on image processing, which comprises the following steps: acquiring a wind power blade image, and performing color space conversion on the wind power blade image to obtain a converted image; performing noise pixel filtering on the converted image to obtain a filtered image; dyeing the filtered image by using a preset dyeing mode to obtain a standard image; performing detail enhancement processing on the standard image to obtain an enhanced image; carrying out binary segmentation on the enhanced image to obtain a binary image; and extracting the area, the length and the number of wear textures in the binarized image, and calculating the wear degree of the wind power blade according to the area, the length and the number. The invention further provides a wind power blade wear analysis device based on image processing. According to the invention, the problem of low accuracy of wind power blade wear degree analysis can be solved.
Description
technical field [0001] Embodiments of the present invention relate to the field of image processing, in particular to a method and device for analyzing wear of wind turbine blades based on image processing. Background technique [0002] As a clean and renewable energy, wind energy has become the first choice for countries in the world to deal with the depletion of traditional fossil energy. In areas rich in wind energy resources, if the gravel carried by the wind is likely to cause damage such as scratches, cavities, and cracks to the blades of wind turbines (wind turbine blades), causing wear and tear on wind turbine blades, it is necessary to replace and maintain wind turbine blades in time. Otherwise, the efficiency of wind power generation will be seriously affected. Therefore, the degree of wear of the wind power blades is judged, and then the wind power blades are replaced and maintained in time to improve the stability of the wind power blades. [0003] Most of the ...
