Abstract Augmented Reality (AR) is fast becoming an established tool for the construction industry. Previous research reports on the conversion of BIM geometric models and the implementation of these with marker-based AR, or the use of more wide area AR taking positional input from GPS. Much of this focused on the use of AR in an individual context, so there is need to align AR with the more collaborative nature of BIM. By implementing marker-based AR, and connecting to a cloud-based database, the presented BIM-AR system provides the ability to view, interact and collaborate with 3D and 2D BIM data via AR with geographically dispersed teams. An Agile Scrum Method was used to develop the prototype system including a mobile AR application and a Large Touch Screen application based on and a Model, View, Controller (MVC) approach. Finally, the system was tested and verified using a focus group of construction practitioners.

支持设计和施工的多用户协同 BIM-AR 系统

摘要 增强现实 (AR) 正迅速成为建筑行业的成熟工具。以前的研究报告了 BIM 几何模型的转换以及这些模型与基于标记的 AR 的实现，或者使用更广域 AR 从 GPS 获取位置输入。其中大部分都侧重于在个人环境中使用 AR，因此需要将 AR 与 BIM 更具协作性的性质保持一致。通过实施基于标记的 AR，并连接到基于云的数据库，所呈现的 BIM-AR 系统提供了通过 AR 与地理分散的团队查看、交互和协作 3D 和 2D BIM 数据的能力。使用敏捷 Scrum 方法开发原型系统，包括基于模型、视图、控制器 (MVC) 方法的移动 AR 应用程序和大型触摸屏应用程序。最后，
