The Reality Capture of Ellis Island

Reality capture for rehabilitation and interpretation

NPS拥有一个持续的重点保护项目ed on rehabilitating and interpreting the hurricanedamaged hospital buildings and support structures that were once crucial to the daily operation of Ellis Island, yet had been closed for decades to the public during stabilisation efforts of these endangered structures. 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.

Historically these documents consisted of copyright-free permanent records, like architectural drawings, photographs and written histories. Today, these traditional archival materials are supplemented with laser scan point clouds, photogrammetric models and virtual tours derived from reality capture technologies. This digital data, according to Dana Lockett, architecture project manager for the HDP, is “extremely useful to the project sponsors and a public that thrives on virtual access.”

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 flagshipScanStation P40 over the course of this multi-year effort.

此外，通过将外部相机套件用于扫描仪C10和扫描仪P40作为其现实捕获工作流的一部分，HDP已向公众提供了首次在线虚拟旅行。bob综合app赌博由全景摄影组成，嵌入了超链接点云动画，3D网格和其他解释性的多媒体，为国家纪念碑的原本受限领域创造了一种教育和沉浸式的虚拟体验。

“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.”
