Three-dimensional laser scanning: potential uses for museum conservation and scientific research

Abstract

Recent technological advancements have made a tremendous impact in the fields of biological anthropology and archaeology. Although advancements in DNA analysis have overshadowed other areas of progress in the subfields of biological anthropology, bioarchaeologists are now utilizing many other new forms of technology in their work. In particular, three-dimensional (3D) laser scanning offers a sophisticated method of documenting and studying prehistoric human skeletons. In recent years, portable laser scanning devices capable of creating high resolution images have become available, enabling researchers to scan and archive skeletal collections from archaeological sites and museum collections around the world. 3D laser scanners are inexpensive, simple to operate, and completely non-destructive to human skeletal material. A major benefit is that they offer a cost-effective method of creating a digital record of skeletal collections for museum archives. Since published research using 3D methods typically focuses on sophisticated analyses used to analyze 3D data that are difficult for the novice user to follow, in this paper we provide a simple and straightforward overview of 3D scanning methods aimed at non-specialists. We discuss how these methods can be used to preserve and document osteological material in museums, develop research ideas in the subfields of biological anthropology, and increase the potential for scholarly collaboration.
