Video Surveillance System Design Based On FPGA

With the continuous development of image processing technology, increasing numbers of industry sectors seek for appropriate surveillance solution, and have long ceased to be the realm of public security, proprietary applications in the banking sector. For example, the examination monitoring, real-time exhibition of traffic, prosecutors’ law enforcement, health care and other public safety issues continued escalation status of the security also makes monitor an important standing. Due to the intuitive, clear, informative, real-time, easy centralized management, video surveillance is applied in various occasions.This paper focuses on video surveillance system design, which bases on FPGA technology. SOPC technology is a set of computer technology, embedded development technology, digital signal processing, and will lead the new direction of development in the field of electronic design. It is convenient to construct a complete embedded and programmable system onto FPGA with the use of SOPC technology. Compared with conventional solutions, this proposed design reduces cost, curtails project development cycle and can be well responded to changing requirements in quickly upgrade.The main contents are as follows:(1) Studied the history of video surveillance systems and SOPC related technologies.(2) Designed and implemented Nios Ⅱ soft-core embedded system hardware and programmable FPGA-based hardware.(3) Studied the principle of COMS camera composition and temporal logic, designed and implemented the configuration module of the camera chip, image data acquisition and storage module.(4) Studied the RTEMS real-time embedded systems and programming interface, completed RTEMS running on Nios Ⅱ soft-core. (5) Designed SOCKET programming based on the reality of the TCP/IP protocol, completed the DM9000A network chip hardware design and network driver design.(6) Final detailed validation process of each module design, test results show feasibility and correctness of video monitor system based on FPGA.
