Photogrammetry recording of an Athenian tetradrachm

This episode of Object Matters marks National Archaeology week. Host Dr Craig Barker is joined by Madeline Robinson, Support Officer for the Department of Archaeology at the University of Sydney. In recent years Madeline has overseen a project of recording a number of Chau Chak Wing Museum objects in 3D to be used in digital teaching of undergraduate courses. 

Photogrammetry is a technique that creates accurate and fully textured 3D models from photographs. It can be used to record both landscapes and objects of all sizes; allowing 3D prints and orthoimages (scaled images without distortion or perspective). Madeline discusses the role of photogrammetry in archaeology and museum contexts, and the role of digital archaeology more generally. Together in depth they discuss how she has recorded one of the museum’s numismatic items, a silver coin from Classical Athens and the complexities of recording a small object n 3D through marrying together hundreds of individual photographs and then how that digital recording may be used to allow greater access to the collection. In the discussion they prove that a digital recording of object matters as much as the object itself when it comes to engagement, teaching and research.

Together they discuss new ways of seeing old objects, in celebration of National Archaeology Week.
