Abstract:
This report presents an overview of an android application developed for blind people to
help them walk without help from anyone as it is not necessary that someone is always
available to guide them. So our main scope is to help blind people walk without pending
on anyone. The application is going to be used in fixed environment (indoor), and it will
only be able to detect limited obstacles in start and later we will add as many objects as
we can. The application would be using the rear camera of the phone for detection of obstacles on the way. To use this application, you need to have an android device with
android jellybean 4.3 or later, and your device should have a good camera. Light is very
important factor for this application to work properly. It works by matching the local image
with the model images in the system by matching their key points and features using ORB
algorithm. If the match is found, then voice alert is generated about that object to warn
the user so that he/she can change his/her path or stop to avoid collision with objects. The application would be done using concepts of Digital Image Processing and It would be an Android based application using java language. The tool on which we have developed the application is Android Studio.
