Abstract

Bu çalışmada gerçek zamanlı bir görüntü işleme
sisteminin tasarımı Zynq mimarisi ve model tabanlı tasarım araçları
kullanılarak gerçekleştirilmiştir. Sistemde FPGA ve mikroişlemci birleşiminden
oluşan yeni bir mimari olan Zynq-7000 yongasını barındıran bir geliştirme kartı
kullanılmış ve bu sisteme uyumlu olan yüksek çözünürlüklü bir kamera ile alınan
görüntü üzerinde gri ton dönüşümü, kenar bulma, gürültü giderme ve
keskinleştirme filtreleri uygulanarak gerçek zamanlı bir biçimde işlenmiş olan
görüntü monitöre aktarılmıştır. Sistemde kullanılan filtre donanım tasarımları
HDL kodu yazılmadan Matlab/Simulink ortamında HDL Coder aracı kullanılarak
gerçekleştirilmiştir. Kameradan görüntü alan sistemin donanım tasarımı Xilinx
firmasının geliştirdiği Vivado Suite isimli araçla yine model tabanlı olarak
gerçekleştirilmiştir. Son olarak tasarlanan donanıma uygun yazılımın geliştirilmesi
yapılarak sonuçlar ve sistemin kaynak kullanımı incelenmiştir. Yapılan çalışmalar
sonucunda sistemin gerçek zamanlı olarak başarıyla çalıştığı görülmüştür.

Design and Implementation of a Real-Time Image Processing System Using Model-Based Design Methods

Abstract

In this study, design of a
real-time image processing system was implemented using Zynq architecture and
model-based design tools. System uses a development board that includes
Zynq-7000 chip, a new architecture which consists of FPGA and microprocessor,
and the images were captured with a high-resolution camera compatible with this
system. Processed images transferred to the monitor in real-time with applying
grayscale conversion, edge detection, noise reduction and sharpening filters.
The filter hardware designs used in the system were implemented by using HDL
Coder tool in Matlab / Simulink environment without using hand-coded HDL. The
hardware design of the system that takes images from the camera has been
implemented with the model-based hardware development tool Vivado Suite which
developed by Xilinx company. Finally, an appropriate software for the hardware
has been developed and results and the resource usage of the system have been
analyzed. As a result of the work done, it has been observed that the system
works successfully in real time.
