基于FPGA的双通道实时图像处理系统

针对基于PC机式图像处理系统实时性不强,FPGA+DSP模式成本高、资源利用不充分、设计难度高等问题,设计了一种新的双通道实时图像处理系统.以一片FPGA芯片为核心处理器,利用红外热像仪和CCD摄像机采集视频图像,经AV视频线送至ADV7180完成视频解码,图像处理模块通过Verilog语言、内嵌DSP硬核以及Nios II处理器予以实现.实验表明,系统实时性强、图像处理效果良好,并具有成本低、设计简单、应用灵活等特点.

Dual-channel Image Real-time Processing System Based on FPGA

In order to overcome the problem of weak real-time for image processing system based on PC, high cost, inadequate use of resources and difficult to design for FPGA+DSP module, a design of new dual-channel image real-time processing system is proposed. The system takes an FPGA chip as key processor, capture video image by CCD and Infrared imaging system, which sent to ADV7180 chip bye AV cable to realize video decoding, the most important image processing module is implemented through Verilog HDL, embedded DSP hard-core and Nios II processor. The experiment results show it has strong real-time and good image processing effect, in addition to, has low cost simple design, flexible application and so on.
