The Reality Capture of Ellis Island

Reality capture for rehabilitation and interpretation

NPS有一个持续的保存项目，旨在恢复和解释飓风损坏的医院建筑物和支撑结构，这些建筑物曾经对埃利斯岛的日常运营至关重要，但在这些濒临灭绝的结构的稳定工作中已封闭了数十年。This multi-year effort, largely funded by Ellis Island (part of the Statue of Liberty National Monument) through its visitor and concession fees, is being carried out by the NPS’ Heritage Documentation Program (HDP), which is tasked by the NPS with creating guidelines and standards for the documentation of the United States' architectural, engineering and landscape heritage.

从历史上看，这些文件包括无版权的永久记录，例如建筑图纸，照片和书面历史。如今，这些传统的档案材料已补充了激光扫描点云，摄影测量模型和来自现实捕获技术的虚拟游览。亚博ag真人规律HDP的建筑项目经理Dana Lockett表示，该数字数据“对项目赞助商和在虚拟访问方面蓬勃发展的公众非常有用。”

The NPS has been using Leica Geosystems’ laser scanning solutions for reality capture since 2006 as part of the HDP. The terrestrial laser scanning technology is incorporated extensively into the HDP’s workflows, and Ellis Island has seen the technology’s evolution, having been scanned with a Leica ScanStation II, ScanStation C10, and now the flagship在这项多年的过程中，扫描仪P40。

Additionally, by using the external camera kit for the ScanStation C10 and ScanStation P40 as part of its reality capture workflow at Ellis Island, the HDP has provided its first online virtual tour to the public. Composed of panoramic photography, embedded with hyperlinked point cloud animations, 3D meshes, and other interpretive multimedia, the tour creates an educational and immersive virtual experience of an otherwise restricted area of the National Monument.

“The evolution of this laser scanning technology has paralled the complexity of the structures surveyed at Ellis Island,” said Paul Davidson, Historic American Buildings Survey architect for the HDP. “As that complexity has increased, the Leica Geosystems scanners have risen to meet that challenge in speed, accuracy and efficiency.”
