ABSTRACT
The appearance and development of cracks in the concrete bridge will seriously affect the safe use of bridge buildings. In order to better satisfy the crack detection requirement, this research comes up with an image preprocessing scheme combining multiple adaptive filtering and contrast enhancement based on the image processing technology of concrete crack, which can improve the removal effect of background noise and obtain the characteristic vein information of tiny cracks. Then we designed a improved sobel operator and integrated with other operators for removing isolated noise spots, so as to extract the crack edge information and improve the positioning accuracy of the crack boundary.
