1. “What can Photogrammetry Do for Your Museum? Practical Info and Case Studies” (Panel)
CHI Director Carla Schroer will participate in a panel at the annual MCN conference whose theme this year is “The Invisible Architectures of Connected Museums.” Carla and three other presenters will offer short case studies of current projects. The purpose of the session is to present practical information about the use of photogrammetry for 3D capture of museum objects. There is increasing interest in collecting 3D data about museum material to meet a variety of objectives, including monitoring changes to objects over time, comparing similar objects, documentation of installations, measurement of features in an object or series of objects, 3D printing of replicas for exhibition or sale, public engagement, and many more uses.

UC Berkeley with National Park Service and National Geographic: Science for Parks, Parks for Science: The Next Century
Carla Schroer and Mark Mudge present new tools and research for Reflectance Transformation Imaging (RTI) and Algorithmic Rendering (AR) digital documentation techniques. These techniques are designed for scientific imaging for examining fine surface details of objects and are being applied to a variety of archaeological contexts and materials, as well as to art conservation. The data is collected using digital cameras and processed using open source software, making the techniques inexpensive to use. RTI is particularly useful for discerning difficult to read inscriptions found in a numerous materials including rock art. The technique can also be applied to study tool marks and aid in other research about how materials are made. The presentation will include new tools and new research methods that are expanding the range of applications of these techniques. This talk will also present examples including inscriptions, rock art, manuscripts, and lithics.

Metropolitan Museum of Art: Conservation Talk
“Advances in Computational Photography Techniques for Art Conservation and Digital Documentation” (Presentation)
CHI Director Carla Schroer will discuss new tools and research for Reflectance Transformation Imaging (RTI) and 3D photogrammetry as applied to art conservation and digital documentation. Since the original form of RTI, Polynomial Texture Mapping (PTM), was introduced in 2001, the technique has largely been used as an interpretive tool, allowing an imaging subject’s relighting from any direction and associated mathematical enhancements that facilitate discovery of surface feature details. New tools and approaches are enabling the same image sets captured to generate traditional RTIs to be used for monitoring physical changes in subjects over time. Research at Princeton University and Simon Fraser University in collaboration with CHI is showing significant improvements in the accuracy of the surfaces calculated from RTI data sets. New tools to enhance the collection and organization of technical metadata for RTI will be presented. Examples of the use of photogrammetry for producing detailed, measurable 3D models will also be shown.
New York, NY: Metropolitan Museum of Art, Uris Education Center, Art Study Room; Thursday, December 11, 2014, 11:00 am
New College of Florida: Natural Science Seminar
“Advances in computational photography techniques for cultural, historic, and natural history materials” (Presentation)
Carla Schroer, Director of CHI and an alumna of New College, presents advances in robust new imaging tools from the emerging science known as computational photography. The common feature of the computational photography imaging family is the purpose-driven, selective extraction of information from sequences of digital photographs. Carla's talk will describe robust photography-based digital techniques for use with a wide range of cultural and natural history materials and associated research. She will demonstrate the use of these tools in a range of contexts including fine art conservation, research of museum and library collections, and documentation of rock art. Examples of existing and cutting-edge uses of photography-based imaging will be presented, including Reflectance Transformation Imaging (RTI), Algorithmic Rendering (AR), and methods of image-based generation of textured 3D geometry.
