Most of the existing pavement image crack detection methods cannot effectively solve the noise problem caused by the complicated pavement textures and intensity inhomogeneity. In this paper, we propose a novel fully automatic crack detection approach by incorporating a pre-selection process. It starts by dividing images into small blocks and training a deep convolutional neural network to screen out the non-crack regions in a pavement image which usually cause lots of noise and errors when performing crack detection; then an efficient thresholding method based on linear regression is applied to the crack-block regions to find the possible crack pixels; at last, tensor voting-based curve detection is employed to fill the gaps between crack fragments and produce the continuous crack curves. We validate the approach on a dataset of 600 (2000 × 4000-pixel) pavement images. The experimental results demonstrate that, with pre-selection, the proposed detection approach achieves very good performance (recall = 0.947, and precision = 0.846).
