摘 要：“实时视频采集及预处理系统”其主要目的是：实时采集标准PAL制视频，并且对采集到的无压缩的视频信息进行预处理，然后将处理后的有用信息传送软件系统进行高级处理。由于本系统采集视频数据的数据传输率高达40MB/s，所以必须采用当今主流的PCI总线与PC相连。
 本设计主要是将噪声信号产生器产生的信号、存储、经PCI接口送入主机供应用软件使用，在本次设计中用一个白噪声信号发生器来模拟产生图象的数字信号。

Design of PCI Interface

 Abstract:The system of real time video frequency collection and pretreatment is the subsystem of the system with 3D laser colorful scanning. Its first objective is to collect the standard PAL video frequency with real time, and to pre-process the video frequency without being compressed, then to send the useful information after processing to the software system that processes this information. Because the data bit in this system is as high as 40M/S, we have to use the PCI Bus that is prevailing now to connect with PC.
 This design is the noise signal creation machine creation signal and save and was connected by PCI primarily arithmetic figure signal that a people sends into the host supply uses the software usage, imitating to produce the portrait in the convenient a noise signal in this design occurrence machine.
