This paper studies the basic principle of the fractal theory, and analyses fractal characteristics of the road crack external form. The fractal dimension characteristic construction algorithm is designed by self-similarity of fractal dimensional and its mathematical expression form. Then road crack texture fractal extraction and analysis is highlighted based on one dimensional fractal. At last, it is compared with regional division combined methods segmentation by testing. The results show that the fractal dimension is a kind of effective quantitative method to depict road crack characteristics, and the algorithm can extract various road crack feature effectively and improve the fracture identification precision and intelligence.
