A Detection Method of Cracks and Structural Objects of the Road Surface Image

Notation This paper introduces a new detection method of crack and structural objects, whiteline , joint and manhole of the road surface image based on mor- phological t,echnique . Crack and structural objects are difficult to detect directly at the pixel level be- cause of the noise and the vagueness. Some kind of structural information is needed. In the proposed method, we have used morphologcal operations which are able to extract specify shapes explicitly . Although the method requires the setting of some parameters, it is robust for detecting vague crack and st(ructura1 objects in the noisy road surface im- age.
