Intelligent Video Surveillance Technology Research and Application

In recent years, the whole society attaches more and more importance to the research and application of video surveillance technology. With the rapid development of intelligent video surveillance technology, so that more and more applications to all corners of society. This technology can be used both in large public places and more secluded private places.

Intelligent video technology is a comprehensive technology that incorporates a variety of currently advanced technologies within itself. Therefore, this technology can effectively ensure social security, but also in the police pursuit of criminal suspects and other aspects to provide some help. To a certain extent, this can better help our country to accelerate the development of this technology.

Developments in Video Surveillance Technology

1.1 Analog Video Surveillance

It mainly uses analog equipment, and if in which all the year round analog video surveillance system is used, then generally it is also known as CCTV surveillance system. It mainly relies on analog video matrix and analog tape recorder technology to achieve the purpose of monitoring, and analog camera video signals can be transmitted through the video cable, so that the monitor can be reflected. Analog surveillance video system through the video recorder can save the image, but the saved image can only be seen in the monitoring center, and it can record less information.

Because its advantage lies in the video, audio, signal transmission and storage of certain analog, but from the working state, it has a number of shortcomings, such as transmission distance is relatively short, may only be within the range of 100m, so generally it will be used in a small area for monitoring.

1.2 Digital Video Surveillance

Digital video surveillance system is a new type of surveillance system with digital video processing technology as the core, computer or embedded system as the center, video processing technology as the basis, using image data compression technology and photoelectric sensors, computer networks, automatic control and artificial intelligence and other technologies. In addition to all the functions of traditional CCTV surveillance system, digital video surveillance system also has remote video transmission and playback, automatic anomaly detection and alarm, structured video data storage and other functions.

1.3 Intelligent Video Surveillance

Intelligent video surveillance technology is the use of computer vision technology for automatic processing, analysis and understanding of video signals, without the need for human intervention, through the sequence of images automatically analyze the changes in the monitoring scene for positioning, identification and tracking, and on this basis to analyze and judge the behavior of the target, can be in the case of anomalies in a timely manner to send out an alarm or to provide effective information, and efficiently assist the security personnel to deal with the crisis, and minimize the phenomenon of false alarms and omission of the report.

Application of Intelligent Video Surveillance Technology

-Applications in Intelligent Security Systems

First of all, in the future may target recognition and tracking technology will be intelligent video analytics system in the lower level of a technology, but a variety of new technologies also need to be based on, so for the time being can not be discarded. And today's target recognition and tracking technology if there is a large gap in light intensity, there may be other blocking, or dynamic background interference and other issues, this will not achieve the desired results to a certain extent. So the play needs to carry out deep innovation of this technology, at the same time in the algorithm can not be stagnant, to optimize it, so as to improve the adaptability of the algorithm, so that it can be adapted in a variety of environments.

Currently used intelligent video analysis technology, usually intelligent analysis of a video scene, so to some extent, can not be timely and effective in the accurate analysis of multi-channel video signals, which requires more camera tracking technology work, in-depth research, the future it can be applied to go to identify a wide range of search targets, so the technology to a certain extent can provide a great deal of help, but also more accurate analysis and judgment.
