Preservation Technology: Comparing and Contrasting 3D Laser Scanning and Photogrammetry

The increased use of preservation technology allows archaeologists and other researchers to examine, analyze, and share data from digital records without harming fragile originals of artifacts. This poster reports the results of comparing and contrasting 3D imaging methods using a NextEngine 3D Laser Scanner verses Photogrammetry using Agisoft Metashape. We choose to use a woolly mammoth tooth, excavated in the Nizhny Novgorod region of Russia that dates from at least 10,000 years ago to compare the two different methods. The tooth was chosen over other materials because the variation present, with multiple, complex layers, planes, and ridges allow the technology to display the full range of their abilities. The methods and associated programs are assessed to establish the accuracy of color, design, and shape. In this poster we will discuss the techniques used as well as the advantages and disadvantages between photogrammetry and 3D Laser Scanning. This study will assess and contribute to the existing knowledge of preservation technology by presenting insight on the credibility and efficiency of the software programs. This project reinforces the significance of preserving and documenting artifacts for public accessibility.
