【摘要】 介绍了一种基于RS422数字接口的PCI总线的单通道数字视频采集系统,可实现30帧/s的1024×1024像元10bit的数字视频采集。系统的核心技术是利用高速数据采集卡进行实时数字图像信号采集,并持续的将采集来的信号数据记录到计算机硬盘上。采集部分可用于PCI总线的视频系统或独立的视频设备中。更多还原

【Abstract】 A single-channel high speed data acquisition system based on RS422 interface of PCI bus is introduced, which can grab digital video up to 1024×1024 pixels and 10 bit depth at 30 frame rate. The system’s kernel technology is to realize real time image signal processing using high speed data capture card and record the data to the hard disk of computer consistently. The grabber can also be used in video system with PCI bus or independent video device.更多还原
