为配合多波段图象实时融合系统的研制 ,设计和开发了高速、高集成度 ,并具有广泛通用性的前端视频信号采集系统 .该系统的设计和开发采用了专用视频解码芯片和大规模可编程逻辑器件 (EPL D)以及 VHDL 语言 .系统具有集成度高、可靠性好、性能优良、体积小、接口简单、采样参数在线可编程修改等特点 .其应用于多波段图象采集和融合系统中 ,作为前端图象采集部分取得了良好的效果 .同时 ,该设计也可作为前端图象采集部分用于其他图象处理系统中
To cope with the development of multi-band real-time image fusion system, a high-speed, highly integrated front-end video signal acquisition system has been designed and developed.The design and development of the system uses a dedicated video decoder chip and a large-scale Programmed Logic Device (EPL D) and VHDL language.The system has the characteristics of high integration, good reliability, good performance, small size, simple interface and programmable sampling parameters online modification.It is used in multi-band image acquisition and fusion system , As the front-end image acquisition part has achieved good results at the same time, the design can also be used as the front-end image acquisition part for other image processing system
