In December 2015, a three-person team from Cultural Heritage Imaging (CHI) spent four days on site at City College of San Francisco using the technique of photogrammetry. In this video, Mark Mudge and Carla Schroer of CHI describe the planning, equipment, tools, data collection, and image processing they employed to document the mural and attain the optimum 3D geometric data, resolution detail, and color fidelity.
This video presentation was shown at the National Center for Preservation Technology and Training (NCPTT) 3D summit in April 2017. ncptt.nps.gov/events/3d-digital-documentation-summit/
