| Research Abstract |
In the field of architectural design and city planning, physical scale model, CAD and VR are acknowledged as effective tools for communication among stakeholders. However, they are often made using different processes so that much labor and high costs are involved. Therefore, an automatic 3D digital modeling system based on a physical scale model is needed. A 3D modeling flow from the physical scale model to the digital data by using 3D Laser Scanner is established. Three problems in this flow were pointed out, namely that the scanning data has too many vertexes and polygons, there are jagged ridges on the edge of the scanned data and spotted losses. Thus, software for resolving these issues, "Poly-Opt" is developed. The experiment showed that the proposed system was effective.
