| description | The invention provides a nuclear power plant containment outer surface defect automatic identification method and apparatus. The method comprises the steps of obtaining a to-be-detected image of a containment outer surface; processing the to-be-detected image to obtain a shadow removal image of the outer surface of the containment; enhancing defect features in the shadow removal image, and obtaining a defect feature enhanced local image; identifying defect pixel points in the local image, and drawing according to the position of each defect pixel point to obtain a defect pixel point coordinate graph; and obtaining an identification result of the defect of the outer surface of the containment according to the defect pixel point coordinate graph. The method is used for solving the problems of high industrial danger, easy missing detection and false detection and the like in the traditional manual detection of the outer surface defects of the containment vessel of the nuclear power plant, and can find the outer |
