“Three-dimensional reconstruction of Roman coins from photometric image sets”, a 2017 Journal of Electronic Imaging paper by Lindsay MacDonald, Vera Moitinho de Almeida, and Mona Hess.
The present study combined two datasets representing the surface topography of the two Faustina coins (Fig. 1). First, they were scanned by a 3-D color laser scanner, producing a point cloud of the surface shape. Second, they were photographed in an illumination dome with directional lighting. The two representations were combined to produce a digital elevation map (DEM) of each coin with the accuracy of the scanner and the fine detail of the photography.
