| With the development of technology, the video surveillance system is developing to the direction of embedded,digital,and networked. The embedded of video monitoring system makes full use of large-scale integrated circuits and scientific and technological achievements of network, realizing compactable, stable, convenient monitoring products.In this paper, the embedded of remote video monitor system based on S3C2410 of core hardware platform has been successfully developed,and the key technologies have been researched and discussed. Firstly, the overall hardware and software system design are given, vivi has been modified and transplanted for the hardware. The transplantation of the compiler and production of Linux kernel, file system of YAFFS also be studied in detail. It is focused on the developing of USB camera interface driver under the embedded Linux operating system, gathering video data used Video4Linux API function. Secondly, the technology of video motion detection which used the background difference method is reseached, video data compression which used MJPEG algorithm is implement, and then the video data which based on TCP / IP protocol of the socket programming sent over in the network. Finally, the paper focuses on the realization of the embedded Web server design, compiling the home page program of video surveillance, implementing the structure of the monitoring system based on B / S model.The modular design approach is used in the system which makes the design more compactable, efficient, and ease to upgrade.the method of embedded for the syste??kes lowe??st, easy to use in promote. |
