In this paper, the authors describe a method of pre-cut components in finishing the interior works using 3D laser scanner.
To implement the pre-cut is required for the following three methods. Firstly, the authors develop the benchmark system for matching three coordinate system ― existing building, point clouds and 3D CAD. Secondly, the authors develop the method of automatically seeking the couple of the targets for transforming the coordinates. Thirdly, the authors develop the design method by polygon model.
The authors scanned the reinforced concrete building and then applied those methods using 3D laser scanner.
