Digital enhancement of the 3D scan of Suhi I's stele from Karkemish

This work describes the procedures that have been adopted in the three-dimensional survey of the hieroglyphic Luwian basalt stele from Karkemish found in 2011, using laser scanning and image processing. The stele has a surface that has quite deteriorated in some parts, especially in line 4 of the inscription, making it hard to interpret some specific parts of its contents. A process has been put in place that has significantly improved the readability of the engraved text in order to carry out its interpretation by the philologists. The main issues related to modern surveying of epigraphs are briefly presented, together with the instrumentation and the methodology adopted and the results obtained for the present case.
