| The improvement of computer technology and integrate circuit design technology, promotes the development of embedded system greatly. The subject designes and implementes moving target tracking video monitor system on FPGA,which bases on the principles of embedded system design and uses SOPC technology. The camera of monitor system tracks moving target in real time to monitor and to collect image data, and complete local storage and network transmission.The paper mainly describes target detection and tracking algorithm which is used by moving target detection video monitor system based on embedded system, and describes the implementation of SOPC embedded system design based on FPGA.The specific contents are as follows:(1) Surveying and analysising the drawbacks of basic solutions of video monitor system in security currently,the paper puts forward to implement intelligent security monitor system, which bases on embedded system and moving target detection tracking technology.(2) Analysising and comparing frequently-used moving target detection tracking technology which is used in video field,the paper puts forward to use the basic method which is background subtraction-based in embedded system moving target detection tracking which is studied in this subject.(3) Basing on the principles of embedded system design and using SOPC technology,The paper proceeds system designment on FPGA.(4) According to the requests of real-time processing and network transport in the system,the paper transplants the embedded real-time operation system uC/OS-â…ˇand LwIP protocol on the hardware platform.(5) Basing on DE2-70 development platform,the paper completes synthesis,fitter and program using Quartusâ…ˇsoftware for SOPC system. The subject combines the basic knowledg of video image analysising and processing, basic principles of embedded system designment and SOPC system designment method based on FPGA.The monitor system implemented has distinct advantages in cost and consumption. |
