Abstract
Este proyecto consiste en el diseño de una cámara estéreo, adaptada para que su control se realice mediante un micro-controlador embebido. La cámara estéreo tendrá unos registros internos, en los cuales el micro-controlador puede escribir órdenes y leer el estado de la misma. El micro-controlador que se utilizará para el control de la cámara estéreo será Microblaze. A este micro-controlador se le introducirá el Sistema Operativo Petalinux, que servirá de interfaz entre el usuario y Microblaze. Microblaze se comunicará con sus periféricos a través del bus de comunicación PLB (Processor Local Bus), por lo que se diseñará un módulo de la cámara estéreo que permita la comunicación a través de este protocolo. La cámara estéreo captará varias imágenes instantáneamente, para lograr con la unión de estas una única imagen con efecto en 3D (3 Dimensiones). Las imágenes se almacenarán en varias memorias externas de tipo RAM (Random- Access Memory), y el número de estas será igual al número de imágenes que se quiera captar. En este proyecto se captarán tres imágenes como máximo. Para el diseño de la cámara estéreo se utilizará un lenguaje de programación hardware, llamado VHDL (Very High Description Language). Una vez diseñada la cámara estéreo se procederá a la comprobación de su funcionamiento mediante simulación con la ayuda de la herramienta Modelsim. _____________________________________________________________________________________________
This project consists of the design of a stereo camera, adapted to be controlled by an embedded micro-controller. The stereo camera will have some internal registers, on which the micro-controller can write commands and read the status of the stereo camera. Microblaze will be the micro-controller used for the control of the stereo camera. In this micro-controller will be inserted Petalinux operating system, which will serve as interface between user and Microblaze. The Microblaze will communicate with its peripherals via the communication bus PLB (Processor Local Bus), so it designed a stereo camera module capable of communicate through this protocol. The stereo camera will capture multiple images instantly, and with the union of this, achieves a single image, with effect 3D (three dimensions). The images will be stored in external memories RAM (Random-Access Memory), and the number of these will be equal to the number of pictures that you want to capture. At this project will be a maximum of three images. For the design of the stereo camera is used a hardware programming language called VHDL (Very High Description Language).Once designed the stereo camera, it will proceed to the verification of its efficiency through simulations with the assistance of ModelSim tool.
