Diseño e implementación de un prototipo electrónico de reconocimiento de objetos y asistente de navegación para personas con discapacidad visual mediante visión artificial

Abstract

In this project, a prototype is developed that assist in the mobility of people with visual disability. This system has two operation modes, the first allows the user to navigate in closed environments and the second is capable of recognizing objects that surround the user, in both operation modes, the user is alerted by voice messages reproduced by a single headset. In order to achieve the aims of this work, the first step is to carry out a compilation of commercial electronic navigation aid systems for blind people, which will serve as support to know relevant characteristics of these systems that can be used in current work. The first chapter has information about the mechanisms for identifying objects and generating obstacle-free routes, which serve for the development of this work. The second chapter shows the hardware and software design process of the prototype, also the development of the different algorithms implemented are explained. Finally, the third chapter presents the tests of the prototype with young people and adults, including people with and without visual disabilities.
