| Along with the continuous increase of vocational education support, increasing investment, vocational campus covers an area of expanding, construction scale is gradually increased, significantly increased the number of students in the school, each campus training place for student’s density. Do a good job in campus safety to defend the work and timely response to emergencies and to school for effective security become the focus of secondary vocational schools and social concern. At the same time, the application of computer network technology in the campus gradually mature, the campus multimedia technology into classroom teaching in secondary vocational school, using technology to improve the management ability of intelligent campus, "civil defense" to "safety" transformation and upgrading is to improve the security capability and an important way to build a harmonious campus environment. In order to ensure the daily life of the school normal teaching order and the teachers and students, improve the campus security precautions capacity, intelligent monitoring system built in the vocational school, high quality, intelligent daily safety and teaching management is very necessary.In this paper, the Jiaxing City a public vocational school campus intelligent video monitoring system design and build as an example, development of intelligent video surveillance system, build were studied. Firstly, the various stages of the development of the video monitoring system to do a general introduction, affirmed its intelligent development direction, further analysis of the working principle of the intelligent video surveillance system; and then analyzes the dynamic target detection algorithm is more popular in the field of intelligent video surveillance system technology, and puts forward the algorithm for moving target detection five frame difference and edge detection, and motion detection algorithm and the traditional dynamic target detection five frame difference and edge detection are analyzed; then according to the actual situation of vocational campus design of the intelligent video surveillance system with the character of school, expounds the equipment selection, the system framework, and the supporting software platform for the use of specific functions; at the end of the overall operation of the system are summarized and the content can be improved. |
