【摘要】：历史建筑具有一定的科学价值、历史价值、文化价值与艺术价值,而如今越来越多的历史建筑遭到破坏,如何为历史建筑进行保护提供永久性的资料,已成为如今急需解决的一大难题。另一方面,建筑信息模型指导施工,可以提升项目生产效率、缩短工期、降低建造成本、提高建筑质量,但是如何对BIM技术指导建筑施工的质量进行检测,是如今建筑领域的又一难题。传统的测量技术很难解决建筑领域这两个难题,三维激光扫描技术以其非接触性,可以快速全面地获取建筑物表面点的三维坐标,可以将建筑物信息以点云记录下来,为历史建筑的保护、修复、重建与BIM技术指导建筑施工质量检测提供了技术支持,为解决这两大难题打下了基础。本文采用三维激光扫描仪对合肥工业大学主教学楼这一历史建筑进行了数据采集,获取了主教学楼的整体点云,并基于点云绘制建筑立面图、进行墙面平整度检测与三维建模,也制作了主教学楼的点云漫游、全景虚拟展示与三维模型虚拟漫游,进行数字化存档,为之后的保护提供了永久性资料;还对上海迪士尼BIM施工现场进行了扫描,将点云与建筑信息模型进行了对比,以丰富的对比成果对BIM技术指导建筑施工质量检测进行了研究。
[Abstract]:Historical buildings have a certain scientific value, historical value, cultural value and artistic value, but now more and more historical buildings have been destroyed, how to provide permanent information for the protection of historical buildings. On the other hand, the construction information model can improve the production efficiency, shorten the construction period, reduce the construction cost and improve the construction quality. However, how to test the quality of building construction guided by BIM technology is another difficult problem in the field of architecture nowadays. The traditional measurement technology is difficult to solve these two difficult problems in the field of construction. Because of its non-contact nature, 3D laser scanning technology can quickly and comprehensively obtain 3D coordinates of building surface points, and can record building information by point cloud for the protection and restoration of historical buildings. Reconstruction and BIM technology provide technical support for construction quality inspection. In order to solve these two problems laid a foundation. In this paper, the 3D laser scanner is used to collect the data of the historical building of Hefei University of Technology, and the whole point cloud of the main teaching building is obtained. And based on the point cloud to draw the building elevation map, wall flatness detection and three-dimensional modeling, also made the main teaching building point cloud roaming, panoramic virtual display and 3D model virtual roaming, digital archiving. Permanent information is provided for subsequent protection; The construction site of Shanghai Disney BIM is scanned, and the point cloud is compared with the building information model, and the construction quality test guided by BIM technology is studied with abundant comparative results.
