基于FPGA和DSP的图像实时采集处理系统设计

摘要

针对高分辨率图像的实时播放、存储，提出了一种基于 FPGA和DSP架构的图像实时采集处理方案．本方案以两片TI DM368系列DSP为核心处理器，采用 H．264编解码方式进行图像的编解码，以 EP2C35系列FPGA芯片作为协处理器进行图像的采集、颜色空间的转换及编解码后图像的传输．该方案能够对红外、可见光两路视频图像进行处理，运行可靠稳定，接口易更改，经过简单修改实现多种格式视频码流的采集处理．%For the real-time broadcast and storage of the high-resolution images,a real-time image acqui-sition and processing scheme based on FPGA and DSP architecture is proposed.In this system,two DSPs in series of TI DM368 are designed as core processors for image encoding and decoding with the encoded mode of H.264.FPGA in series of EP2C35 is used as coprocessor for image acquisition,color space conversion and the images transmission after encoding and decoding.This scheme realizes the vide-o and image processing for the infrared and visible light and results show that the operation is stable and reliable,the interfaces are flexible.In addition,several formats of video stream can be acquired and pro-cessed by simple modifications.
