The Blind Reader is a small, affordable device designed to help blind people read printed text. Traditional Braille machines can be very expensive, so not everyone can buy them. The Blind Reader is different because it's cheaper and easier for more people to use.
This device works using a small computer called a Raspberry Pi and a webcam. Hereโs how it works step-by-step:
1. Capture the Text: You place a page with printed text under the webcam. The webcam takes a picture of the page.
2. Convert Image to Text: The Raspberry Pi uses a technology called Optical Character Recognition (OCR) to convert the picture into digital text. This means it reads the image and understands what letters and words are on the page.
3. Process the Text: The device makes sure the text is clear and readable. It fixes problems like the text being at an angle or having multiple columns. This process is called skew correction and segmentation.
4. Read Aloud: Once the text is clear, the Raspberry Pi uses a Text-to-Speech (TTS) program to change the text into spoken words.
5. Output the Audio: The spoken words are sent to speakers through an audio amplifier, so the sound is loud and clear.
At Takeoffprojects, The Blind Reader is a complete system that helps visually impaired people by reading printed text out loud. It's easy to use and portable, which means you can carry it around and use it anywhere. This device makes reading more accessible for blind people, helping them become more independent and gain better access to information. Projects on OpenCV like this demonstrate the power of technology in improving lives.
