Outline

This session introduces the concept of 3D imaging: capturing imagery, geometry, surface or volumetric features, etc. of an existing heritage object to create a digital model. After a very brief overview of techniques and tools, from geophysics, computed tomography, laser scanning to RTI and photogrammetry, we look at a couple of case studies using remote sensing and drone photography to record the progress of excavation at an archaeological site. We will end by suggesting a practical exercise that students can attempt at home using any camera or mobile device, and free (trial) software, and discussing important questions for the scholarly use of 3D image data, including methodology and documentation.

Resources

Exercise

Following the advice in this session (supplemented by the video tutorials listed below if you need them), practice the technique of photogrammetry on a small object or local monument.

  1. Install Agisoft Metashape on your computer, and activate the free 30-day trial license.
  2. Take c. 40–80 photographs, using a camera, phone, tablet, etc, making sure to capture every possible angle of the object in overlapping images.
  3. After deleting any blurred or overexposed images, import them into Metashape and run the three steps (align photos, build mesh, apply texture), and both save your work as a project and export it as a 3D model.
  4. [If applicable.] Bring your work to share with your tutor and fellow students at the next class.
