A study on road surface defects detecting technology with CCD camera

In this paper, a new algorithm dealing with the detecting image of road surface disease is established. On the basis of classic algorithm, through improving the traditional filter algorithm, crack edge checking algorithm and image division algorithm, image characters of the crack like disease of road surface are analyzed and studied. Real road cracks such as transversal cracks, lengthways cracks and anomalistic cracks are treated and distinguished. The results show that the detected images are clear and the continuity of crack edges is very good.
