Machine vision-based concrete beam crack pattern identification using fractal theory
Based on the modern image recognition technology, this study used the fractal theory to examine the surface cracks of concrete and the fractal dimension was used as an index to identify the bearing capability of concrete components. Through processing and simulating the experimental data obtained by other researchers, the relationship of crack fractal dimension D and the loading-ratio ξ of the concrete component was calculated. The D-ξ relationship of concrete beams is D = 0.1684 ξ + 1.0307. Based on this relationship, a fast evaluation method based on the fractal dimension of the crack surface to judge the bearing capacity of concrete components was proposed in this study, and its accuracy was verified by the analysis of experimental results.
