Historical Coins in 3D: Acquisition and Numismatic Applications
Sebastian Zambanini, Mario Schlapke, Martin Kampel, Arne Müller · 2009
This paper addresses the 3D acquisition of historical coins and evaluates its benefits over the current documentation method by means of 2D images. We present preliminary results on creating full 3D models of coins from the Roman and medieval times using a state-of-the-art active stereo scanning device. Furthermore, we discuss the results from numismatic point of view and highlight the different fields of numismatic research where a 3D analysis is of high value, including documentation, measurement and identification. The results show that accurate 3D models can be obtained despite the small size (typical diameter of about 15-30 mm) and specular surface of historical coins.
