摘要
为有效提高视频监控应用领域中多屏幕画面显示的清晰度、分辨度等问题,提出了一种基于FPGA的实时视频图像处理算法。文中介绍了系统的整体结构,然后针对FPGA模块介绍了视频图像的缓存及图像分割,并针对视频的输出显示要求,重点介绍了基于双线性插值算法的实现。ModelSim的仿真结果表明,该算法符合多屏幕显示系统的要求。
In order to efficiently improve the image definition and resolution of multi-screen splicing display sys- tem in video supervision, a real-time video image processing algorithm based on FPGA is proposed. Firstly, the o- verall structure of the system and video image cache and image segmentation in FPGA module are introduced. Then the bilinear interpolation algorithm is presented according to video display requirements. Simulation by ModelSim shows that the algorithm does conform to the requirements of multi-screen splicing display system.
