Development of Digital Design Processing System for Architectural or Urban Design Field

在建筑设计和城市规划领域，物理比例模型、CAD和VR被认为是利益相关者之间沟通的有效工具。然而，它们通常使用不同的工艺制造，因此涉及大量劳动力和高成本。因此，需要一种基于物理比例模型的自动三维数字建模系统。建立了利用三维激光扫描仪从实物比例模型到数字化数据的三维建模流程。指出了该流程中存在的三个问题，即扫描数据顶点和多边形过多、扫描数据边缘存在锯齿状脊和点状丢失。因此，开发了用于解决这些问题的软件“Poly-Opt”。实验表明，该系统是有效的。

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.
