Decapod is a project focused on building a low-cost digitization solution that will allow for rare materials, materials held in collections without large budgets, and other scholarly content to be digitized into a high-quality PDF format. This project will work to incorporate the off-the-shelf hardware and open source software necessary to accomplish this goal.
This guide provides information on how to set up equipment and how to work through a Decapod workflow.
This documentation applies to Decapod 0.7. |
Decapod has four different workflows:

Tethered: Decapod controls the cameras using USB cables. With tethered capturing:
Unetethered: The cameras are used independently of a computer and the images are stored locally on the camera using a memory card. With untethered capture:
Stereo 3D Capture: Two cameras are mounted side-by-side and used to create a stereo image of the book content. With the Decapod Stereo 3D Dewarp application, stereo images of books can be flattened to remove distortions caused by page curl.
Conventional Capture: One or two cameras are used to simply capture images of a book. With two cameras, one camera would take a picture of one page, with the other camera capturing the opposite page.
