Design and Implementation of Digital Image Processing System Based on DSP+FPGA Architecture

摘要:

为了实现视频图像的实时处理，采用基于DSP FPGA的线性流水阵列结构，用现场可编程门阵列FPGA对采集的视频数字图像做预处理，并结合大规模可编程逻辑阵列CPLD进行逻辑控制，实现了视频图像的采集和目标提取的视频数字图像处理系统。介绍了该视频图像处理系统的硬件组成、工作原理和各种视频跟踪算法的应用。该系统与计算机联结，配以适当的图像处理软件和开发系统，即可形成一个通用的实时图像处理平台。

Abstract:

The real-time digital image processing system are presented based on DSP+FPGA architecture, which is a part of photoelectric tracking system on scout.The real-time digital image process DSP(digital signal processor) system are discussed, which is high-speed intelligent and programmable. The system uses height-performance DSP (TMS320C6203B) to realize the real-time digital image process algorithm,in the same time uses large-scaled programmable logical array CPLD to control logic and field programmable gate array FPGA to preprocessing the image. The application of digital image process algorithm for complex background is introduced. It proved to be a reliable and effective for the request of system basically. A method of high speed image template match using TMS320C6203B is introduced. The image template match has been solved the processing speed problem of in current digital image processing systems.
