Currently intelligent video analysis technology is broadly divided into three categories, with the fault diagnosis for the purpose of maintaining class intelligence analysis; to check the video information for the purpose of identifying the intelligent analysis; to automatically analyze and track the behavior of the class-based intelligence analysis. Peace building in the city, identify the class of intelligent analysis techniques in electronic police system has gained a mature application, especially in license plate recognition, the domestic intelligence analysis technology has reached world advanced level. In the three categories of intelligent video analysis, video analysis of the main diagnostic categories is to improve their efficiency in the use of video surveillance, improve the user experience for video surveillance systems maintenance operation plays a very important role. Video analysis is to identify the class focuses on the ability to retrieve video information, the focus is to enhance the effectiveness of video surveillance applications. In contrast, analysis of the behavior of the video object class is to identify not only the activity information, the more important is the ability to automatically process the information. If PTZ auto-tracking monitoring. So not only become an extension of video surveillance of human vision, but an extension of the brain thinking.
PTZ is a Pan / Tilt / Zoom shorthand, on behalf of monitoring head round (up and down, left and right) to move and zoom lens, the zoom control. Automatic intelligent autonomous PTZ tracking enables the network camera to pan and zoom on their drive for self-PTZ and PTZ cameras automatically control the PTZ camera pan, tilt and zoom, visual guide for the locked automatically track moving targets to ensure continuous target tracking to enlarge close-up screen appears in the center of the lens, so that security personnel can more clearly see the information, but also can be used after the evidence. Automatic PTZ tracking module fixed to make up the shortcomings of the narrow field of view camera surveillance, security monitoring system is perfect for the essential functions. Intelligent PTZ tracking and monitoring system with automatic target analysis, and is equipped with high-resolution cameras, high-magnification optical zoom lens and high-speed PTZ, you can quickly and accurately capture the suspicious target automatically. By setting the preset auto-tracking PTZ intelligent visual surveillance system can achieve preset scan, auto cruise function, but also to achieve many special requirements of intelligent monitoring. Another intelligent visual surveillance PTZ auto-tracking system also has the good looks, concealment, etc., and therefore very suitable for airports, squares, rail transportation, villas, government administrative units, military, museums and other places of various types of intelligent security monitoring applications .
Current video surveillance systems most widely used features is that image recording function, which is the video. Faithful chronicler of the scene is now positioned on the public perception of video surveillance. In the development of video surveillance, and networking, high-definition, integration, personalization and other trends, is still centered on how to play a video function more effectively. And then for intelligent video surveillance will produce a revolutionary role, particularly in-depth analysis of the development of behavior class video, video surveillance systems will mean an autonomous intelligent security systems. Intelligent video analysis system for video surveillance will become active after the defense evidence, making the cost of the project can most provinces, to achieve the most effective security.
Intelligent video analysis as a cutting-edge technology of video surveillance, awareness of the market is still not high, the circle of this technology is currently only extended to the integrator at this level, a lot of video analysis techniques suitable for application scenarios yet to be market development. But intelligent video analysis of the market is composed of many small market segment composed of new applications are constantly emerging. Application and popularization of new technologies need to go through a certain stage, and we should see in intelligent video analysis technology is mature and needs of the market test. Development of intelligent video analysis technology is bound to bring video surveillance into a new period of development also means a new growth pole of the security industry. Overall, intelligent video analysis is a microcosm of the era of intelligent human society, and the behavior of the class video analysis is one of a highlight.
