Paper Abstract

Road cracks in the highway surface are very dangerous to traffic. They should be found and repaired as early as possible. So we designed the system of auto detecting cracks in the highway surface. In this system, there are several key steps. For instance, the first step, image recording should use high quality photography device because of the high speed. In addition, the original data is very large, so it needs huge storage media and some effective compress processing. As the illumination is affected by environment greatly, it is essential to do some preprocessing first, such as image reconstruction and enhancement. Because the cracks are too tiny to detect, segmentation is rather difficult. This paper here proposed a new segmentation method to detect such tiny cracks, even 2mm-width ones. In this algorithm, we first do edge detecting to get seeds for line growing in the following. Then delete the false ones and get the information of cracks. It is accurate and fast enough.
