marker-crop: Automated, Reliable Postprocessing

Post by duerig » 29 Jan 2017, 22:33

One of the biggest problems with book scanning as it is now is the time-consuming and cumbersome postprocessing. I've been working on a way to provide a basic postprocessing workflow that is completely automated with no human intervention.

In order to do this, a user places markers on top of the platen as they scan to indicate where to crop the book and what the orientation of the book page should be. Since the markers are physical tokens, the user can see visually what will be cropped and adjust the markers as they scan.

Right now, I'm beta testing this software and if it proves to be as reliable and automatic as I want, I'll roll it into Pi Scan to make it easier to use. But you can try it out right now if you have a Linux or Mac machine and can install OpenCV. See the project page at:


It will always be the case that for some people and some projects more complicated post-processing is necessary. But my goal is to make at least the most basic kind of post-processing completely painless with no need to review the book hunting for problems.

Please give me any feedback you have. Especially if you find situations where it doesn't work.
