[Abstract]:Compared with the traditional video surveillance, embedded network video surveillance has many advantages, such as low cost, low power consumption, high reliability, network management and interaction, and so on. With the development of embedded technology and image processing technology, the mobile target detection and monitoring system based on embedded network video surveillance has its active monitoring. With the advantages of greatly improving the monitoring efficiency, mobile target detection and monitoring has gradually become a research focus in the field of video surveillance. In view of the defects that the traditional video surveillance is passive monitoring, the recorded video image data needs a lot of space, the monitoring efficiency is low, and the specific personnel are often required to monitor 24 hours a day, a mobile target detection and monitoring system focusing on active monitoring technology is designed in this paper. Mobile target detection is an important branch of computer vision technology application, the purpose of which is to realize the moving target in the monitoring area. For example, vehicles, pedestrians and so on carry out real-time video capture and detection, and store the information of interest to these users as an important basis for the analysis of field conditions, in order to achieve the purpose of active monitoring, saving resources and improving monitoring efficiency. The specific design of the system is composed of several parts. On the basis of the analysis of the requirements of the article, the hardware and operating system composition of the system are determined. The S3C6410 processor produced by Samsung Company is selected as the system processing core and Linux as the operating system running. On this basis, the peripheral hardware design and software design of the system are gradually determined, and the system framework is built. Then, the video capture and compression in the system are gradually explained. The key technologies that need to be solved in the transmission process are solved, and an embedded Web server is set up based on B / S mode to view the monitoring scene in real time. Finally, the system application is tested and evaluated with moving target detection as the core. The experimental results show that the mobile target detection and monitoring system designed in this paper not only has the functions of video capture storage and network monitoring in traditional monitoring, but also can warn the moving targets in the camera monitoring area, actively capture and store, realize the active monitoring target, and has a great application prospect.
