Description
This paper proposes laser image binarization for crack detection by fractal dimension. Laser image is one of the road surface image and can be obtained by observing scattering light of laser from road surface. It has the advantage of robustness of lighting condition over an image that is taken by optical camera. However, surface asperity of road manifests as texuture regions in these images. So, crack detection method needs to be deal with texture regions. Although many of conventional methods geared toward concrete construct, these methods do not work well to road surface image. Proposed method can evaluate a texture region and binarized laser image effectively through the use of blanket method locally and globally.
