摘　　要：针对红外/电视视频数字化、传输网络化的发展趋势,基于最新大规模逻辑FPGA和高性能DSP芯片,结合图像处理理论,提出红外/电视视频数字化采集、压缩与网络化传输方法,单路视频码率小于15Mbit/s,视频延时小于20 ms。该平台为后续研究基于红外/电视视频信号的目标检测、特征研究和模式识别等提供了基础,在指/火控系统等领域有着广泛应用前景。In order to realize the digitization and transmission networking for infra-red/TV video, based on the lastest high performance FPGA and DSP, combined with the image processing theory, a digital acquisition, com- pression and networking transmission platform of infra-red/TV video is proposed. By the practical validation, the compression data rate is less than 15 Mbit/s, the delay time is less than 20 ms. The platform provides the basis for further research on object detection, character extraction and pattern recognition, and has a wide ap- plication prospect in command and fire control system.
