PopSci reports a researcher at the University of Tokyo has developed a machine that can digitize books at a rate of up to 200 pages per minute. The new method uses a camera system to capture rapidly flipping book pages, it's up to four times faster than other book scanners.
The scanner's camera runs at 500 frames per second, and captures rapidly flipping book pages in two modes. First, a regular line shines on the page to capture text and images. The second mode then manages neat the trick of reconstructing the curved, distorted pages in their original form. A laser device projects lines onto each page that the system can use to recreate the 3-D page model and correct the deformed lines.
