Implementación de un dispositivo identificador de billetes para personas no videntes

Abstract

The present project describes the construction of a prototype of identification of the denomination of the bills like the help for the introduction of people with visual disability in the occupational area through the PROCODIS foundation. The development and implementation of the prototype there are some steps: first, we made the logical design and investigated about the libraries of OpenCV applied to artificial vision, then use them in the code of programming using Python. Then, it was determined the characteristics of each of the components of the device and its connection with the Raspberry Pi, to finally determine the physical design of the same, taking into account characteristics such as: the dimensions of the wooden box and the Distribution of electronic parts for later implementation. Finally, it presents the implementation and operation of the prototype, which is based on the identification of the denomination of the ticket through a camera connected to a Raspberry Pi, which captures an image, to process it in search of referential patterns of identification, that is to say, analyzes the image that was captured with respect to the database of images stored in the MicroSD memory. With the help of a speaker and a voice message is allowed to inform a blind person the value of the bill consulted and thus detects the denomination.
