Road Crack Edge Detection Based on Wavelet Transform
IOP conference series Earth and environmental science(2019)
摘要
In this paper, the edge detection of road surface crack images is studied. The traditional edge detection algorithms such as Gaussian-Laplacian and Canny operator are used to extract the edge of the crack. The experimental results show that the edge extraction is not complete and sensitive to noise. Therefore, the modern wavelet analysis method is adopted to extract the complete and accurate crack edges.
