Design And Implement Of The Client Software For Network Video Surveillance Based On Web

With the rapid development of computer technology and the expansion of the Internet, the development of video surveillance industry has made great breakthrough, the field of application has been extended to all walks of life, and gradually penetrated into people’s daily life, the development of surveillance industry also will develop towards diversity and intelligent in the future.The development of current surveillance system generally use C/S model, but more and more problems exposed, such as the complexity of system upgrades, high maintenance costs, based on the disadvantages of C/S mode surveillance software in this paper, we design and realize a client software of video surveillance based on WEB. It uses the browser as the client, using the embedded device to capture H.264video stream, rely on the wireless network transmission, transport protocols use the RTP/RTCP protocol, the signal interaction of the video surveillance client software use the TCP/IP network protocol, finally embedded the ActiveX controls in the browser to play the video with the DirectShow. Surveillance industry compliance with the current market demands and the development trend of the future, it has good practical value. The main contents are as follows:1. Based on the disadvantages of C/S mode surveillance software, a overall design scheme of B/S mode surveillance software is put forward. According to the module of front-end equipment, Web servers and Web client for the overall design, focusing on the design of Web client, including the design of user operation interface, the design of ActiveX control and the design of CGI program.2. According to the functional requirement of surveillance software, a concrete implementation plan of B/S mode surveillance software is put forward. Including two parts:The first part is the realization of the user operation interface, including user login interface, video playback main interface and video information configuration interface; The second part is the realization of the surveillance software function modules, including video module, audio module and motion detecting module.3. For the problem of the edge of objects produce jagged after image magnification of the video surveillance software, a kind of study on the algorithm of video quality improvement plan is put forward. By inserting the interpolation algorithm in the DirectShow of the video playback platform, improve the image of the CIF format video after magnified four times, simulate the result after improved and assess the quality of video image.
