Diseño y construcción de un sistema electrónico para personas no videntes como ayuda para el cruce de las calles urbanas basado en el procesamiento de imágenes.

Abstract

The following graduation projects propose the design and construction of an electrical system for blind people like help at the moment of moving by the urban streets of the city. Within the planned work is expected to be helpful in the social field and even for blind people, in the development of their daily lives, through technology and artificial vision. Through the processing of images, the system was immersed in a prototype In the first module the capture of images of which will be processed was carried out. In stage two the processing of the images will be done, In order word, by means of an algorithm and determine the type of signals that have and finally to finish the process a message will be sent to the user indicating the traffic signal that is in the image. The modules communicate in a wired way; this process is carried out on a Raspberry Pi 3 card. The prototype implementing, allows to capture images on urban roads to determine what type of pedestrian signal exists within the image captured by the camera, if there is any pedestrian signal in the image a voice message will be issued to the user, based on that information, the user can make decisions when crossing the street and can do so more safely. The prototype consists of three stages or modules that are described below. It was evaluated taking 20 tests, of the different pedestrian signals in the prototype, of which an average of 77% of effectiveness was obtained. It is concluded that it is a prototype able to meet the established expectations to improve the lifestyle of people with disabilities.
