A Portable Structured Light System for the Rectification of Printed Text
نویسنده
چکیده
The goal of this project is to develop a portable structured light scanner which can capture the 3D structure of arbitrarily warped printed text and then rectify it. The resulting rectified text can then be sent to a standard OCR engine for recognition and layout analysis. The rectified image of the text can also be used as a reference image for non-rigid surface detection. Pairing non-rigid surface detection with the OCR results provides an infrastructure for augmented reality applications. The system is wearable and consists of a pico projector, a webcam, and a portable computer. This project is part of an on going effort to implement an assistive reading device for the visually impaired.
