In order to repair pavements systematically, development of a method for inspecting pavement distress automatically is being hoped for. It is difficult, however, to classify crack types directly have two or more types of connected cracks. This necessitates segmentation of regions containing overlapping and connected cracks so that crack types can be classified properly. This paper proposes a method of segmenting crack region using crack elements extracted from images of pavement surface. The proposed method consists of three steps: (1) encording the orientation of connection using low-resolution images of pavement surface, (2) reencording by using pavement images of hierarchical resolutions, and (3) segmenting the reigions by tracing and merging the pixels encoded as linear regions. By applying the method to images of actual pavement surface, the author succeeded in identifying transverse and longitudinaly crack regions, two-dimensional crack regions, and isolated crack regions. The proposed region segmentation method has made it possible to apply conventional crack types classification techniques to actual pavement surface.
