Development of a guide dog system for the blind people with character recognition ability

Abstract

This paper introduces a guide dog system with character recognition ability. The main purpose of this system is to assist blind people. A guide dog helps a visually impaired person to act corresponding to the surrounding environment. However, it cannot do complex tasks such as reading words. We constructed a system that can read characters to support them. Usually, character recognition systems segment character from the general background by using some information. This time, our system focuses exclusively on reading a room number. Therefore, we used a method of character searching by template matching.
