Documenting and Archiving a Large Scale Diego Rivera Mural
Friday, April 5, 2019,4:00 pm - 5:00 pm EDT
As part of the Data Science Seminars, Carla Schrorer, a co-founder and director of Cultural Heritage Imaging (CHI), will give lecture on “Documenting and Archiving a Large Scale Diego Rivera Mural”. She will show high-resolution 2D outputs and share the experience of capturing the fine surface details of a 22ft by 74ft 1940 fresco mural by Diego Rivera.
A photogrammetry-based, high-resolution 3D model of the mural was captured with 2,200 50-megapixel images. From this data, a 7.4-gigapixel-perspective-corrected 2D digital image of the complete surface of the mural was created, along with a registered Digital Elevation Model (DEM). A DEM is a 2D false color image visualizing the 3D surface shape of the subject. In the DEM it is possible to see brush strokes in the plaster, patches to the plaster, giornata lines, and important conservation information such as cracks. The lecture will include a discussion of the metadata and archiving strategy for the project.
