基于三维激光扫描技术的文保构筑物测绘及建模适用性探讨

Discussion on the Applicability of Mapping and Modeling of Cultural Preservation Structures Based on 3D Laser Scanning Technology

摘要: 根据文物保护的勘察需要，针对文保构筑物测绘的技术难点，采用三维激光扫描技术，以碉堡和城墙构筑物为例分别进行应用介绍，基于点云数据现状还原的特点，大大提高了测绘成果的深度和准确性。另一方面，对于文保构筑物的三维建模，通过分析多种主流三维建模软件的功能，结合不同类型构筑物的特点，最终在碉堡建模上推荐Geomagic系列，在城墙建模上推荐Sketchup，上述软件在操作和文化表达上均有较好的适配性。

Abstract: According to the investigation needs of cultural relics protection, aiming at the technical difficulties of mapping cultural preservation structures, 3D laser scanning technology is adopted to introduce the application of blockhouses and city wall structures respectively. Based on the characteristics of point cloud data status reduction, the depth and accuracy of surveying and mapping results are greatly improved. On the other hand, for the 3D modeling of cultural preservation structures, by analyzing the functions of a variety of mainstream 3D modeling software, combined with the characteristics of different types of structures, I finally recommend the Geomagic series on bunker modeling and Sketchup on city wall modeling. The above software has good adaptability in terms of operation and cultural expression.
