Recognition of cracks on the concrete surface in digital images
When one estimates the quake resistance of the steel reinforced concrete structure, or the deterioration degree of materials, cracks on the concrete surface are extremely important factors. However, the conventional judgment technique using cracks needs great man power. In this study the authors use a digital camera and some image processing methods and simplify the cracks measurement process to get more precise information of cracks. In this research the authors propose a new method of processing the images of cracks, in the hope to reduce the difficulty of conventional techniques. The authors take a photo of a concrete surface, and preprocess it, then they analyze several characteristics of the image, especially for line parts, and cracking part will be extracted by grayscale conversion, edge enhancement and Hough conversion method.
