Product Label, Obstacle and Sign Boards Detection for Visually Impaired People

Abstract

From the ancient days, visually impaired people had been facing many problems.In this scenario due to heavy traffic there is a chance for them to meet with an accident due to the absence of vision. In addition it becomes necessary for them to depend on others while crossing the roads, to recognize the product labels and to identify the directions in the one way roads. This work helps such people to overcome those problems.This work uses camera module for identifying directions and product labels. The camera captures the label image of the product which is in front of it, detects the product label image and then the image is separated using openCV library. It also uses ultrasonic sensors for identifying obstacles. The output can be heard by impaired people in the form of voice signals through earphones. All this work is carried out by using raspberry pi 3 module B+ with python software. This work helps the visually impaired people to find obstacles which appear in front of them. It also helps in identifying product label and sign boards on the road.
