Abstract:
Based on the analysis of the characteristics of images of bridges' cracks, some special image processing algorithms, such as the edge detection, were used in order to obtain the cracks length and width. As the result of study, based on modern image processing theory, one completed system that including hardware and software was developed. The compared test of the existing bridge with cracks under the out-door environment shows that the new technology is suitable to do the long distance non-contacted crack detection of bridge structure. 1 tab, 4 figs, 9 refs.
