Summary
This is an abstract from the session entitled "The Nuts and Bolts of Ships: The J. Richard Steffy Ship Reconstruction Laboratory and the future of the archaeology of Shipbuilding" , at the 2020 annual meeting of the Society for Historical Archaeology.
Past decade, photogrammetry has become one of the most frequently used recording methods on archaeological research projects. This quick and inexpensive tool has conveyed advantages on recording underwater sites. Using photogrammetry, archaeologists and researchers can extract various information from 3D digital models without revisiting archaeological sites. However, due to its nature, underwater photogrammetry finds several unique difficulties; one of the main obstacles is exceedingly blue-colored 3D models. In underwater environment, red and green colors were consumed by water and every objects’ colors turn into blue.
The author uses color-checkboard to successfully restore original colors of archaeological sites. Also, he applies methodologies to acheive accurate and precise mesh reconstruction in order to converted them into a site plan. In this paper, the author shares those color-collection and mesh-reconstruction methodologies as step-by-step photogrammetry workflow.
