Corrosion Quantification on Reinforced Concrete Surfaces Using Image Analysis

The article considers possibility of determining corrosion quantitative assessment of reinforced concrete structures using the processing of images obtained from visual control technical means. The average saturation value of all pixels is calculated. Quantification is carried out by measuring the area of corrosion at various threshold values and determining the centers of areas location with a high degree of corrosion in the image. The result of program is selection of areas with a certain quantitative content of corrosion products. The use of proposed algorithm in practice will allow in automatic mode, together with video endoscopic systems, to determine the corrosion state of reinforced concrete structures on hard-to-reach surfaces.
