Proof of concept and initial results
The technology, intended for digital documentation and analysis of archaeological finds, makes use of optical scans of the artifacts which generates accurate 3D digital models. Sophisticated algorithms analyze the 3D models, extracting precise object measurements, and thereby providing a powerful tool for typological analyses and classification. This analysis reveals compelling information - otherwise unavailable using traditional documentation - including distinctive characteristics and production techniques of workshops and of individual craftsmen. It also eliminates the need to manually draw artifact saving on costs and time.
The artifacts are scanned using a high-precision commercial 3D optical scanner. A set of proprietary software programs position and measure the artifacts, computing various attributes which characterize their shape. The programs draw the objects and produces printer-ready documentation of the artefacts, in compliance with the Archaeological standards.
Two separate programs are provided for processing artifacts, according to the type and geometry of the objects:
The Artifact3-D program for artifact documentation and analysis (after Grosman 2016). The Neolithic mask is from the Israel Museum Collection, exhibited at the Israel Museum, Jerusalem.
The two software programs are already being utilized intensively for documenting and analysing of artifacts. So far, more than 60,000 artifacts, retrieved from over 100 archaeological sites, were scanned and analysed. Our aim is to improve the user interface and to add several innovative analytical options.
