Abstract:

Blind people are always cursed in the sense of vision. In this world characters are found everywhere. This paper focuses on the Raspberry Pi Reader for blind people that assists them in recognizing the characters. The system can be used for converting images of either handwritten or printed text into machine coded text. For this purpose Optical Character Recognition (OCR) technology is used. The images are captured using a Pi camera module mounted on a stand. The Open CV Library is used for converting scanned images into machine text. The Tesseract Platform (library) is used to assist the OCR Technology. The encoded text is then converted into an audio output (speech) through TextSpeech Synthesis method. Python programming is used by Raspberry Pi for conversion of printed image to text file and then to audio output. Here we introduce a simple and portable reader that efficiently and effectively converts text into audio output in a proper way.
