Camera Detection for Blind People Using OCR

According to the World Health Organization, there are millions of visually impaired people in the world. This paper is based on the development of a system that provides aid to such people. A pi camera is used to implement the system which is based on the Tesseract OCR (Optical Character Recognition) library of OpenCV in Raspberry pi. OCR library is used to recognize text from the captured image by the pi camera module. This helps to convert the picture of the desired page taken by the camera into respective text. Finally, this text is converted into speech through headphones using the TTS (Text-to-Speech) Engine. A headset is used for hearing the converted speech. The text-to-speech application assists them to detect text from printed documents and avoiding obstructions while traveling hence a blind person can feel not visually impaired.
