3D in the Toolbox: An Operational Comparison of Acoustic, Photogrammetric, and Laser Scanning Methodologies Tested at Thunder Bay National Marine Sanctuary in 2016. (2017)
DOCUMENT Citation Only John C. Bright.

The clear, fresh waters of Thunder Bay National Marine Sanctuary offer an ideal testing ground for acoustic and light-based imaging systems. During the 2016 field season, Thunder Bay researchers conducted several field operations to acquire, process, and compare side scan sonar, multibeam sonar, laser-scanner, and photogrammetric data at numerous archaeological shipwreck sites. The resulting analysis provided valuable insights into this array of remote sensing systems in terms of their ability...


Archaeology, Accessibility and 3D Imaging (2017)
DOCUMENT Citation Only Hillary Kiazyk.

The recent incorporation of 3D imaging into the field of archaeology has opened many doors with regards to accessibility of archaeological materials. While this promotes research by inviting a much broader research discussion, it also poses questions of ownership of materials. This poster will explore new ways that archaeologists, descendant communities and people of the general public are now interacting with archaeological materials as well as some of the challenges, benefits and problems...


High Resolution Imaging of Stone Tools from the 1st Millennium BC, Grand Cocle Region of Panama: A Digital Archive Initiative (2017)
DOCUMENT Citation Only Patricia Hansell.

Archaeological investigations often result in large quantities of stone and ceramic artifacts which, after being catalogued and analyzed, are stored in accessible places and rarely used for further research, student training or public education. Digital technology is changing this. It is revolutionizing the way we do research, archive our results and communicate with others. Based on a sample of time- or functionally-sensitive stone tools from the 1st millennium BC component at the...


Low-cost System for Image-Based 3D Documentation in Archaeology (2015)
DOCUMENT Citation Only Nazih Fino.

The paper presents an image-based scene reconstruction algorithm for the 3D documentation of a lighter boat from the Gold Rush Era. It follows the structure-from-motion approach and uses low-cost equipment that is part of the standard documentation procedure at an archaeological site---a digital camera and a total station. Points measured with the total station are used to transform the model into the projected coordinate systems used at the excavation site such that measuring and...


Obsessively Opacifying Obsidian: Adapting Three Dimensional Laser Scanning Techniques (2015)
DOCUMENT Citation Only Christopher Swoger.

Three dimensional (3D) imaging technologies are being increasingly utilized by archaeologists to improve the accuracy of material analysis. To facilitate the development of these technologies, it is crucial to determine the limits of different devices and materials. This project focused on the challenge of scanning obsidian blades with the Next Engine HD 3D Laser Scanner, a popular and inexpensive choice among researchers. The Next Engine device was used to scan six small obsidian blades from...


Underwater 3D Imaging with Structured Light: Implications for Ethics and Economics (2015)
DOCUMENT Citation Only Christopher T. Begley. Anne E. Wright.

A prototype underwater 3D imaging technology is discussed that is both inexpensive and creates accurate, high resolution 3D data. We focus on the connection between this technology and archaeological ethics and economics. First, we discuss a cutting edge, low cost, highly portable and user-friendly 3D imaging system using structured light, which has generated very high resolution images in both terrestrial and underwater contexts. Next, we compare it to other low-cost 3D techniques. Finally, we...


Using 3D Laser and 3D Sonar as Tools for Mapping, Analyzing Site Formation Processes, and Long Term Monitoring of Shipwrecks (2015)
DOCUMENT Citation Only Melanie Damour. Robert Church. Daniel Warren.

3D imaging creates a permanent digital record that allows scientists to study minute site details and also serves an important outreach role by allowing the public to virtually explore archaeological resources. While 3D imaging of archaeological sites using laser and lidar is a growing trend in terrestrial archaeology, its application in marine archaeology has only recently emerged. Marine archaeologists are now beginning to use 3D laser- and sonar-derived models as new tools for interpreting...


Yikes, no comparative collection! Can 3D imaging produce robust faunal identifications? (2017)
DOCUMENT Citation Only Melanie Fillios.

Most zooarchaeologists are familiar with the uncertain feeling when faced with identifying material in the absence of a physical comparative collection. In response to this challenge, numerous photographic atlases have been produced to provide researchers with access to collections while in the field. Unfortunately, 2D images are constrained by their inability to be ‘handled’ and measured in the same way as a physical specimen. The UNE Archaeology virtual bone project was initially developed as...
