3D-Edgeangle_test-dataset

This dataset is meant to test 3D-EdgeAngle – A semi-automated 3D digital method to systematically quantify stone tool edge angle and design. The dataset contains a 3D model (stl format), digitalised edges (igs format) as well as the results of the edge angle calculation. The scripts for the 3D-Edge angle have been written with Python in GOM Inspect Professional 2016. The repository containing the scripts is also as available as open access on Zenodo (https://doi.org/10.5281/zenodo.7956767). The 3D model is a model of an archaeological tool (co-called Keilmesser) from the Upper site of Buhlen, Germany. The artefact dates to the Late Middle Palaeolithic. The archaeological finds from Buhlen are normally stored and displayed at the Hessisches Landesmuseum in Kassel, Germany (https://museum-kassel.de/de/museen-schloesser-parks/hessisches-landesmuseum). For more information about the artefact see: Schunk L. Understanding Middle Palaeolithic asymmetric stone tool design and use: functional analysis and controlled experiments to assess Neanderthal technology Verlag des Römisch- Germanischen Zentralmuseums Mainz. https://doi.org/10.11588/propylaeum.1076 The 3D model was produced with an AICON smartSCAN-HE R8 from the manufacturer Hexagon (software version OptoCat 2018R1), featuring a blue light LED and two black and white cameras with 8 megapixels each. The S-150 FOV used has a point-to-point distance of 33 µm. After scanning, the 3D model (STL file) was edited in the free software GOM Inspect 2018 (2018 Hotfix 2, Rev. 111729). The scanning took place at TraCEr, Laboratory for Traceology and Controlled Experiments at MONREPOS Archaeological Research Centre and Museum for Human Behavioural Evolution, RGZM, Neuwied, Germany.
