一种基于FPGA的视频滤波模块的硬件实现

Study on Video Capture Memory System Base On FPGA

在拍摄环境复杂的情况下,视频采集系统采集到的视频信号往往受到噪声的干扰,不能反映被拍摄物的真实情况。本文设计了一种基于FPGA的视频图像滤波模块,能够对采集的视频信号进行滤波处理。该模块采用Xilinx公司XC4VSX25的FPGA芯片作为运算核心,实时性强。利用其强大的整合逻辑资源对视频信号运算处理,使其集中在FPGA片内,具有良好的整合性和可复用性。

In the case of shooting complex environment, the video signal what the video acquisition system capture is often subject to noise interference. It does not reflect the real situation of being photographed object. In this paper, an FPGA-based video image filter module is designed. The module is used in Filtering the video signal processing which are collected in this environment .The module use Xilinx＇s FPGA-chip XC4VSX25 as the core operation and has a very good real-time performance. Meanwhile ,it use the powerful logical computing resources which are integrated in FPGA to process video signal and make the module focused on the FP- GA chip, The method of design make this module has a good integration and reusability.
