中文摘要:

      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15 Mbit/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。

英文摘要:

      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，compression 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 application prospect in command and fire control system.
