NETRA

Netra is wearable device that helps visually impaired people navigate by providing speech descriptions of the world around them. This repository implements Netra Daemon that runs on a Raspberry Pi device connected to the standard PiCamera module. To provide real-time environment descriptions Netra-Daemon needs a Netra Vision server running on a computer. Netra Vision implements a Convolutional-Recurrent Neural network that converts images to text descriptions. Rest of the modules requre Google Vision API authentication to work.
