The Design And Research Of Video Monitoring System Based On SOPC

With the development of computer and multimedia technology, video surveillance system is more andmore extensive application field. Video surveillance system is a set of digital video technology, imageprocessing technology, computer technology, communication technology into an integrated system, withstrong real-time, convenient management control advantages, increasingly in the bank, warehousemanagement, transportation, aerospace, armored vehicles, and other aspects that have been widely applied.Video monitoring system includes an image signal acquisition, image processing, image storage andtransmission, image display and other parts. The traditional video surveillance system is an analog signal,based on the PC resources, only simple video acquisition, display, the system function is complete, but thelarge volume, high price. Now widely used in digital video monitoring system, it is divided into two kinds,one is in digital video equipment as the core of the video surveillance system, another is based on embeddedvideo server for video monitoring system. Embedded monitoring system is currently the mainstream ofdevelopment, it is to use as the center, take the computer technology as the foundation, the software andhardware can be cut, apply to the reliability of system, function, cost, size, power requirements are strictlydedicated computer system.This paper adopts SOPC (System on Programmable Chip) technology design and implementation ofvideo monitoring system, and transplantation of embedded operating system, to ensure the systemexpansibility and maintainability. SOPC technology based on video surveillance system can satisfy thefunction requirement of the system, as a result of the FPGA chip can realize parallel processing, and has asoft hardware programmable capability, the system has high processing capability and good real-timeperformance, and has more flexibility and scalability. The design of Altera chip FPGA, building Nios â…¡ softcore processor. Analysis of the system the realization of each module, and the module of the system ofsystem integration, generates the video monitoring system based on SOPC hardware environment, analysisof the video monitoring system software provides functions and implementation methods, completed thevideo monitoring system hardware design and software design. Finally, the main function modules of thesystem debugging and verification.
