An Introduction to the "Impost" Book Scanner, using Voussoir

Following several design principles of my “Non-Destructive Guillotine”, I introduce a more portable single-camera book scanner design. The scanner uses a hinged platen that works with tightly-bound and paperback books, while allowing the book to sit spine-down at a variable angle. I also introduce a piece of software, “Voussoir,” which semi-automates the process of de-keystoning and cropping images.
