Using Wavelet Technology for Pavement Crack Detection
Edge detection is an alternative method in the process for identifying and classifying pavement cracks for automated pavement management systems. This paper presents a new approach in automation for crack detection on pavement surface images using wavelet technology. Firstly, a separable 2D continuous wavelet transform for several scales is performed. Secondly, wavelet coefficients maximal values are searched through scales. Thirdly, in order to analyze wavelet coefficients maximal values in a window, cracks edges are detected and background noise is deleted. In addition, the paper invents an evolution of edge detection arithmetic to obtain better detection effect. Finally, a simple threshold is employed to indicate the presence of cracks on the pavement surface image. The results of experiments on images demonstrate the validity and effectiveness of this method for edge detection of pavement surface distresses.
