Research And Realization Of A Network Video Image Gathering System Based On DSP

From 1950s to the present, after the development for half a century, the connotation and extension of digital image processing has been extended hugely. Image supervisory system developed under this background. It may carry on real-time gathering and the surveillance to the goal scenery image, and is monitored the place the image completely or partially records, thus provides convenience and immportant gist for the after disposal of some affairs.According to the requirment of the industry scene to produces the environment landscape monitor, this article has designed one kind of general image supervisorysystem------a network transmission video frequency image gathering system based onthe DSP. A video frequency image gathering and network transmission platform was constructed, it is primarily processed by one type high speed DSP produced by TI Corporation, and is has a function of high speed video frequency image gathering, and a function of highly effective image coding compression, and it use industry ethernet and TCP/IP protocol carries on the image data transmission, may make the function which the wireless transmission, USB2.0, the serial port and so on the many kinds of ports protocol and transmission modes expand.The stress of this thesis is the design of software and hardware of a network transmission video frequency image gathering system. In the hardware design of system, the DSP in the system hardware design and the periphery various modules hardware to design and to carry on the detailed connection design are given, which is mainly consisted of image A/D transformation module, DSP image compression code processing module, data buffer module and image network transmission module composition. Designed in the software design has corresponded to the hardware connection first floor software and the image coding compression algorithm procedure, The user may act according to own demand establishment gathering function parameter and the image algorithm.This article content mainly includes:(1) Determined the image gathering transmission system technology route, the technical parameter and complete the system overall design;(2) The image gathering transmission system hardware system design, mainly includes the chip the shaping, various functions module electric circuit design, the...
