Abstract
The present invention provides a method and system for statistics of thickness of corrosion product film based on image processing, comprising obtaining overall image by stitching plurality of cross-sectional images of the corrosion product film on surface of pipeline; obtaining feature area of the corrosion product film by segmenting the overall image; performing division of the thickness layers on the feature area of the corrosion product film according to number of pixel points in vertical direction of thickness; counting the number of pixel points of each of the thickness layers; obtaining the thickness of each of the thickness layers according to counted number of pixel points; and, performing statistics of thickness after obtaining the overall image representing larger area of the corrosion product film on the surface of pipeline by stitching the plurality of images.
