Real-time 3D Page Tracking and Book Status Recognition

Summary

We proposed a new book digitization system that can obtain high-resolution document images while flipping the pages automatically(BFS-Auto). The distinctive feature of our system is the adaptive capturing that has a crucial role in achieving high speed and high resolution. This adaptive capturing requires observing the state of the flipped pages at high speed and with high accuracy. In order to meet this requirement, we newly proposed a method of obtaining the 3D shape of the book, tracking each page, and evaluating the state. In addition, we explain the details of the proposed high-speed book digitization system. We also report some experiments conducted to verify the performance of the developed system.
