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.
Key Word: Operation of PCI Local Bus, PCI Local Bus
