The IP Camera is the ideal platform for intelligent video analysis

The IP Camera is the ideal platform for intelligent video analysis
In the 1990s, led by the Defense Advanced Research Projects Agency of the visual monitoring of major projects VSAM (VisualSurveillanceMonitoring) has attracted the participation of many university research institutions, thus beginning the prelude to the intelligent video analysis technology research and application. So far, the application of intelligent video analysis technology for nearly 20 years, the worldwide deployment of many intelligent analysis system running. But should see the basic intelligent video analysis applications are centralized applications, mostly PC-based applications. With the deployment of network video surveillance system and a number of large-scale monitoring project launched until the last 2,3 years, intelligent analysis system based on embedded devices began to get more attention and application.
Intelligent analysis of high-level applications include regional preparedness, behavior understanding, object recognition, smoke, flame recognition, PTZ tracking, traffic management. Market intelligence analysis application is mostly limited to the area of ​​prevention, intrusion detection, tripwire detection, and other more complex engineering applications is also unusual. On the one hand we believe that intelligence analysis is one of the important direction of development of video surveillance, on the other hand, should also see the intelligent analysis of engineering practice still faces many problems.
The reason is technical reasons, intelligent analysis is absolutely not science, its successful implementation requires a wide range of fit, intelligent analysis technology in the development process; followed by domestic enterprises doing enough in terms of technology accumulation , most OEM foreign companies algorithm, the domestic enterprises to truly master the core algorithm handful algorithm adjustment, it is difficult to make specific scene.
Intelligent analysis technology can be divided in two parts of the underlying modeling and high-level modeling. The underlying modeling including background modeling, target detection, target tracking, feature extraction, such as the basic algorithm, high-level modeling is to be judged according to the preset rules to generate analysis results.
The best equipped platform of intelligent video analysis
The intelligent video surveillance system has just begun the implementation of relevant standards can be based. Coupled with intelligent analysis would have been no standard algorithm, there is no standard indicators, most of the implementation of the project according to the designer's experience and needs of the owners, the system implementation is a matter of opinion.
Intelligent Video Surveillance System with respect to traditional monitoring the most essential difference is that the information to understand and analyze links. Theoretically understanding and analysis can occur at various stages of the data stream, it formed a different intelligent analysis solution. Understanding and analysis of information collected in the distal end unit perform the smart conferred camera, to form a smart camera, and includes analog cameras and IP Camera; understanding and analysis of information is performed in the intermediate unit is formed intelligent DVR devices; understanding and analysis of information of course can also be in the backend The server performs a centralized intelligent monitoring system.
Different solutions have different characteristics, system design requirements are not the same. With respect to the the backend centralized deployment, we think that the front-end processing, distributed processing more competitive, the following reasons: First, the problem of the processing capability. Intelligent analysis requires the image pixel-by-point analysis, a huge amount of computation, when the input video channels more centralized processing processor bandwidth can not support. Distributed processing a single processor capability is not strong, but only handle all the way bandwidth is enough.
Followed by the problem of network bandwidth, the centralized processing need all the video data are transmitted to the server, and distributed processing can be selective transmission according to the analysis result.
Finally, there is the issue of cost distributed processing on the basis of the original hardware without increasing the cost or only very small increase in cost can be realized intelligent analysis of the large ones of the same video is clearly more centralized processing increased costs.
In summary, the IP Camera is the best equipped platform for intelligent video analysis.
