Digital reconstruction of fragmented artefacts: Improved methods for data capture

Abstract

This is a major outcome of a research project addressing the “fragmentation problem” of ancient architectural monuments. The overall research aim was to develop a new methodology for fragment matching using statistical analysis techniques. However, only when sufficiently accurate digital records of fragments exist can computer aided reconstruction take place. To address this imperative, a new digital recording methodology, capable of highly accurate data capture, was developed. The data capture method evolved from the adaptation of recording techniques used in engineering and the paper expands and develops arguments made in previous research. The research resolved the issue of data suitability for statistical analysis, succeeding where earlier attempts by others to solve the problem had failed due to problems of data inaccuracy. Many conservation projects deal with fragment matching and the methodology introduced here provides a foundation for accurate fragment recording that could greatly simplify the fragmentation problem. The methodology has the potential to transform the way archaeological fragments are recorded.
