Duration: Half day
Place: Cultural Conference Centre of Heraklion (CCCH)
Audience Type: Open
This tutorial provides lectures, demonstrations, discussion, and hands-on practice with software tools for creating and validating context and process metadata for photographic image sequences. The initial software is designed for RTI and Photogrammetry, though the approach has broader applicability. The tools produce Linked Open Data mapped to CRM-dig saved as RDF. The user need not know anything about the CRM or linked open data to use the tools.
These tools form the basis of the Digital Lab Notebook (DLN). The DLN serves the same function as a written scientist’s lab notebook, enabling data inspection and reuse by others.
We begin with an overview of both RTI and photogrammetry, including basics of image capture and examples of each from cultural heritage subjects. This will allow participants to understand the structure and approach of the tools. There will then be an exploration into CHI’s approach to metadata collection and image validation, including the hands-on use of new, open source software tools.
Participants are encouraged to bring their laptops for hands on practice with provided sample data.
This Tutorial enables an attendee to:
- Learn about the Digital Lab Notebook (DLN), how archiving and reuse requirements are driving modifications to its development, and how to use it in an RTI or photogrammetry practice.
- Gain a basic understanding of two computational photographic imaging techniques: Reflectance Transformation Imaging (RTI) and photogrammetry for 3D.
- Learn about two specific software tools for collecting metadata about image sequences and validating image sequences, including recently funded plans for additional features and tools.
- Provide an opportunity for hands-on practice with the tools: DLN:Capture Context and DLN:Inspector using provided example data. (Participants will be able to download the software from the CHI website prior to the tutorial – the free software runs on both Mac and Windows PCs)
- Provide feedback on the tools for subsequent versions
- Provide input for additional tools for archiving image sets which are being planned
Cultural Heritage Imaging (CHI)
Carla Schroer is a co-founder and director of Cultural Heritage Imaging (CHI) a non-profit corporation that develops and implements imaging technologies for cultural heritage and scientific research. Carla leads the training programs at CHI, along with working on field capture projects with Reflectance Transformation Imaging and photogrammetry. She also leads CHI’s software development activities. She spent 20 years in the commercial software industry, managing and directing a wide range of software development projects.
