Video Surveillance System Base On SOPC

In now days, due to the rapid developments of computer technology,communication technology, multimedia technology and embedded technology, videosecurity monitoring system has been entered into a digital stage from the traditionalsimulation method. Digital video security monitoring system has computer andnetwork-centric as its center, so its function is very powerful, and it can realize the basicfunctions of video collection, storage and playback, etc, at the same time, it graduallyintegrated the people and object recognition, automatic alarm, network behavioranalysis and wireless transmission and other advanced features.For the application of video security monitoring system, the subject researchand design a remote video surveillance system, it based on SOPC, a programmableon-chip system.This article first introduced the basic concept of the development and currentstatus of video security monitoring system, moving object detection method, the FPGA(Field Programmable Gate Array, the field programmable gate array) technology, SOPCtechnology. On this basis, this article proposed a solutions of video surveillance systembased on the SOPC technology. Then it made a brief introduction of SOPC technology,the used black gold development board and the commonly used resources ondevelopment board. In turn, it used the SOPC Builder tool comes with Quartus ii tobuild the accordingly system soft core processor, NIOS ii, adding peripherals ip nuclear,and designed a CMOS Controller through the system integration.Then, it introduced three commonly used methods of dynamic target detection,optical flow method, the frame difference method and background subtraction method.It improved a basic problem of background updating in background subtraction method,and wrote the corresponding software program. And used the NIOS ii IDE to compilesoftware engineering and downloaded successful compiled program to the hardwaresystem to verify it. Finally, this paper summarized the subject content made in this topic,the lack of experimental and some needed further improvement.
