摘　　要：介绍一种在工矿监视系统中采用FPGA实现视频数据实时采集和显示的设计方案。系统中采用FPGA和视频解码器实现了高速连续的视频数据采集与处理。处理后的视频信号通过VGA格式转换,可以在现场VGA显示器上观看,也可以通过键控将数据存储在存储介质中,从而实现了实时视频监视。A design of real-time video data acquisition and display is introduced, which is realized by adoption of FPGA, using in the system of industrial and mining television monitoring. The chips of FPGA and video decoder are applied to realize the acquisition and processing of high speed and consecutive video data. The consequent video data is VGA format converted and then shown on spot VGA display. Moreover, the data could be stored in media by keying so as to implement real-time video surveillance.
