摘　　要：以电子稳像为背景,为解决难以实时根据偏移量对视频图像进行补偿的问题,设计了基于FPGA的运动补偿系统。对视频进行采集后提取出了灰度分量便于处理;用乒乓存储解决去隔行处理中视频数据量大、硬件资源有限的问题;用片外SRAM作为帧缓存,通过操作读写地址和控制VGA时序实现了图像的平移显示,同时满足实时性的要求。最终实现了对视频图像的实时平移,并最终在VGA上显示。系统全部由硬件编程实现,实验结果表明可以满足功能需求,显示效果良好且扩展性强。With the background of electronic image stabilization,FPGA-based motion compensation system is proposed to deal with the difficulty in compensating the offset of video and image in real-time.The gray-scale component is extracted to facilitate the post-processing.Ping-pang store is used to solve the problem of large amount of data in de-interlacing with limited hardware resources.To realizes the algorithm of translation,motion compensation using chip SRAM as the frame buffer,realizes translation of the image display through manipulating read/write address and controlling VGA timing while meeting the real-time requirements.The system is all finished by hardware programming.The result shows that the system can satisfy function demand with positive effect and strong expansibility.
