Research compendium for 'Practical and technical aspects for the 3D scanning of lithic artefacts using micro-computed tomography techniques and laser light scanners for subsequent geometric morphometric analysis. Introducing the StyroStone protocol'
<p><strong>Abstract:</strong></p> <p>Here, we present a new method to scan a large number of lithic artefacts using three-dimensional (3D) scanning technology. Despite the rising use of high-resolution 3D surface scanners in archaeological sciences, no virtual studies have focused on the 3D digitization and analysis of small lithic implements such as bladelets, microblades, and microflakes. This is mostly due to difficulties in creating reliable 3D meshes of these artefacts resulting from several inherent features (i.e., size, translucency, and acute edge angles), which compromise the efficiency of structured light or laser scanners and photogrammetry. Our new protocol <em>StyroStone</em> addresses this problem by proposing a step-by-step procedure relying on the use of micro-computed tomographic technology, which is able to capture the 3D shape of small lithic implements in high detail. We tested a system that enables us to scan hundreds of artefacts together at once within a single scanning session lasting a few hours. As also bigger lithic artefacts (i.e., blades) are present in our sample, this protocol is complemented by a short guide on how to effectively scan such artefacts using a structured light scanner (Artec Space Spider). Furthermore, we estimate the accuracy of our scanning protocol using principal component analysis of 3D Procrustes shape coordinates on a sample of meshes of bladelets obtained with both micro-computed tomography and another scanning device (i.e., Artec Micro). A comprehensive review on the use of 3D geometric morphometrics in lithic analysis and other computer-based approaches is provided in the introductory chapter to show the advantages of improving 3D scanning protocols and increasing the digitization of our prehistoric human heritage.</p> <p><strong>Content List:</strong></p> <ul> <li><strong>S1. </strong>Step-by-step protocol entitled ‘StyroStone: A protocol for scanning and extracting three-dimensional meshes of stone artefacts using Micro-CT scanners’.

Kiev 60 Film Camera - Artec Spider 3D Scan
This is a 3D scan of a 1990's Soviet-era Kiev 60, a medium format SLR film camera manufactured by the Arsenal Factory in Kiev, Ukraine. Produced between 1984-99, it was inspired by the Pentacon Six. But contrary to wide-spread claims, it is not a Soviet copy, it was substantially re-designed and is an improvement on the Pentacon Six. A great find for anyone wanting to do amateur medium format photography. For more information on the scanner, please visit: https://gomeasure3d.com/artec/spider Source: Objaverse 1.0 / Sketchfab
Small size statue scanned with peel 3d
Here is yeat another great looking statue scanned with peel 3d. This one was smaller in size and harder to scan as it is made of darker material. This is also a statue that got damaged and repaired (poorly :) ). The fine details came out great; I especially like the way the hair look! Source: Objaverse 1.0 / Sketchfab

Fort Gorges - Casco Bay, Maine | Drone 3D Scan
Fort Gorges is a former United States military fort built on Hog Island Ledge in Casco Bay, Maine. Built from 1858 to 1864, no battles were fought there and no troops were stationed there. Advancing military technology, including iron clad ships and long range guns, made the fort obsolete before it could be used. The fort is now a park, accessible only by boat. The fort was recreated using videogrammetry from this youtube video: https://www.youtube.com/watch?v=zI-J8B7GvIg Extracted 119 frames were processed in Agisoft software.
