| With the raising of public safe requirement, the video supervisory system gets the extensive application in many aspects in national life, at the same time, has also been put forward higher requirement. The current video supervisory system need be improved in many ways ,such as the quality of image, the quality of transmission , intelligence and so on . The emphasis of this paper is on the intelligent technology of video supervisory system . Currently the video supervisory system not only has taken a function of saving record or general control, also must make a reaction for the unusual condition that occurs in monitoring area , for example setting up defense and reporting to the police, saving the movement, tracking the movement, identifying the target etc...This paper combines the research project of laboratory: Based on the network video supervisory system of H264, designing a system of motorial target track based on DSP and researching the technology for tracking many targets .The arrangement of paper is as follows:Firstly I introduce the development condition of video supervisory system, at the same time make briefly introduction about the intelligent technology of video supervisory systemSecondly 1 introduce the existing technology of movement detection briefly , at the same time carry out the technique of the trigonal nuclear movement estimation based on DSP.Thirdly I introduce the system of motorial target track based on NMI feature, including the structure of system and the technique of movement partition and movement match.Then according to the movement match based on NMI feature,! carry out the single target track system based on TMS320DM642 . This system can look as many targets track system when targets carry out linear movement.Finally 1 introduce the operation condition of the system and point out many existing problems about designing integrated many targets track system frame .1 make some suggestions for the realization of the system and the theories. |
