تورهای مجازی و مدل سازی اطلاعاتی برای حفاظت از سایت های میراث فرهنگی

Thorough and organized documentation is crucial for conservation of historic structures. While photogrammetry, laser scanning and building information modeling (BIM) have enhanced 3D documentation in conservation, it is imperative that the method of documentation matches the requirements of the project. Present methods are efficient for certain types of projects. However, for projects that need to depict 3D conservation challenges, but do not have the budget or time for a 3D model, a middle ground does not exist. We present an intermediate solution, a workflow for virtual tour environments (VT) and informational modeling (IM) and we test this workflow on a case study. The VT/IM environment we created contains building plans, previous conservation reports, image galleries, databases about past interventions and short descriptions of the conservation issues at Princeton University. In this paper, we compare conservation reports using 2D plans against the VT/IM environment and we compare the time, cost and data management of VT/IM with methods of 3D documentation.
