This product is for the multiple handicapped blind like Helen Keller. It converts image to text in real time and vibrate motors based on braille.
Optical Character Recognition. It converts image to text. We apply this tech after Image process by opencv.
tesseract
tesseract-ocr
Tesseract is an open source text recognition (OCR) Engine, available under the Apache 2.0 license. It can be used directly, or (for programmers) using an API to extract printed text from images. It supports a wide variety of languages.
Knn The k-nearest neighbors (KNN) algorithm is a simple, supervised machine learning algorithm that can be used to solve both classification and regression problems. It's easy to implement and understand, but has a major drawback of becoming significantly slows as the size of that data in use grows.
LattePanda 4G/64G To run knn / OCR , we use SBC
arduiono nano we use arduino nano to control 10 vibration motors.
