摘要

This paper proposes a portable camera-based assistive text reading framework to help blind persons to read text labels and product packaging from hand-held objects in their daily lives.The system framework consists of three functional components: First,scene capture-using a mini camera,the text which the user needs to read gets captured as an image and has to be sent to the image or data processing platform.,second,data processing-where text will be filtered from the surrounding and will be recognized by optical character recognition(OCR)software,and finally,Speech output-A filtered text will be passed into this system to get an audio output.In addition to text recognition using OCR,the project also includes template matching technique as a separate method for recognizing certain objects like currency notes.Since the project should be portable to assist the blind persons,the entire application is based on Raspberry Pi.
