| Research Abstract |
The purpose of this study is to construct a high-definition three-dimensional CAD modelto reproduce the historical town and industrial heritage by using three-dimensional laserscanner. We showed a method of separating architectural elements by the attributes(spatial coordinates, color information, reflection intensity) of the point cloud data.Then, the system for automatically processing point cloud data developed. In addition,we have converted to the CAD data from the point cloud data extracted in each constructionelement. As a result, a set of processes that produce building information model (BIM)from point cloud data is presented.
