Superfast Book Scanner Digitizes Rapidly Flipped Pages
A research team at the University of Tokyo has developed a superfast scanner that can capture rapidly flipped pages and digitize a 200-page book in one minute.
Professor Masatoshi Ishikawa and his team at the University of Tokyo have developed a scanner that allows scanning a book by flipping its pages rapidly in front of a high speed camera. The scanner can digitize a 200-page book in a minute.
Popsci explains the working of this superfast scanner:
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 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.
