This article presents a novel methodology for retrieving three-dimensional geometry from structures that exist only within the historical photographic record. Two shipwrecks that were raised in the early twentieth century are examined as case studies for this methodology. This paper explores the complications of using historical photographs in photogrammetric analysis and demonstrates how the shipwreck point clouds were generated using the iWitness program. In addition, it documents how photogrammetric hull data from historical photographs were scale constrained (using surviving artifacts) and used for the first time to create ship lines for academic study. A test was also conducted to demonstrate the potential accuracy of the photogrammetry program and methodology as a whole. Although the present study uses two raised shipwrecks as case studies, this methodology could easily be applied to other structures that have been “lost.”

本文提出了一种从仅存在于历史摄影记录中的结构中检索三维几何结构的新方法。将在 20 世纪早期发现的两艘沉船作为这种方法的案例研究进行了研究。本文探讨了在摄影测量分析中使用历史照片的复杂性，并演示了如何使用 iWitness 程序生成沉船点云。此外，它还记录了历史照片中的摄影测量船体数据如何受到比例限制（使用幸存的人工制品），并首次用于创建用于学术研究的船线。还进行了一项测试，以证明整个摄影测量程序和方法的潜在准确性。尽管本研究使用两艘凸起的沉船作为案例研究，
