Abstract: In recent years, reinforced concrete has been widely used as a building material having high strength. However, when the arrangement of the reinforcing bars embedded in the inside are not correct, there is a problem that the strength drops greatly. Therefore, when use reinforced concrete, it is necessary to confirm whether the reinforcing bars are correctly arranged. In this paper, we propose a method of thinning of point clouds scanned by range scanner from reinforcing bars, and extracting the core wires of point clouds by introducing a concentration distribution function. This process moves points according to a gradient field of a concentration field. In addition, we conducted an experiment to confirm the effectiveness of the proposed method. As a result of the experiment, it was confirmed that the core wires can be extracted from the point clouds of the reinforcing bars.
