Cracks and Displacement Feature Extraction of the Concrete Block Surface

An efficient measure of the concrete block structure inspection is needed with the increasing demand for concrete blocks. Cracks in the surface of RC member's can be used as a useful measure of quake-proofness of a construction or material fatigue. Specialists used to observe the cracks and experimentally inspect the structures, while applying destructive forces to the blocks. This paper proposes an automatic detection and analysis system for the concrete block inspection. By employing a high-resolution camera, cracks and displacement features are automatically extracted with image processing techniques, which are considered to be efficient for assisting specialists in the inspection procedures
