Abstract
Drilling is one of the most complex techniques for making ancient stone or jade implement or adornment. However, related research on ancient stone or jade drilling technology lags behind, for there are rare records or discovery of the ancient drilling tools. Drilling marks are very useful information for analysis and research of the ancient drilling techniques. The traditional information acquisition methods are very difficult to apply effectively on smaller perforations. In this paper, we introduced a new nondestructive method to solve the observation difficulty problem. The ancient bead was scanned by 3D-μCT system. Then through T-FDK algorithm, improved NL-means denoising algorithm and high accurate calibration, the 3D geometrical information of micro-drilling marks on outer and inner wall of the perforation were reconstructed. The experimental results proved that this method can provide key information for the analysis of the ancient stone drilling technique and ancient jade authentication.
