Ocean buoy production quality detection method

The invention relates to the technical field of image data processing, in particular to an ocean buoy production quality detection method. The method comprises the following steps: acquiring an ocean buoy image and a corresponding buoy edge contour; comparing the difference between the buoy edge contours of the ocean buoy image and the buoy template image to obtain contour similarity; the overall contrast of the ocean buoy image is obtained according to the gray difference between different types of pixel points in the sampling point neighborhood on the buoy edge contour of the ocean buoy image; obtaining the contrast attenuation degree based on the change of the overall contrast of the ocean buoy images obtained at different distances; and obtaining a buoy quality evaluation index based on the contour similarity, the overall contrast and the contrast attenuation degree. According to the method, the contour similarity is obtained by analyzing the surface features of the ocean buoy image, and meanwhile, the qu
