Abstract

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.”
