Abstract
The stone tools and other artefacts produced by pre-European Maori show a remarkable level of craftsmanship, but it is not clear how these tools were produced. Analysis of debitage the fragments left behind at manufacturing sites - offers insight into this process. While an individual stone flake or fragment offers little information, statistics across the entire collection from a particular site are of great archaeological interest. Currently, each individual fragment is measured by hand - a laborious, time-consuming, and error-prone approach. We show that image-based 3D reconstruction of stone flakes can be used to automate some of the common measurements made by archaeologists. We demonstrate our techniques on a small collection of flakes and obtain similar accuracy to manual measurements.
