Since the birth of intelligent video analysis technology in the 1990s, after decades of development, this technology originated in computer vision has been increasingly paid attention by people along with the gradual application of commercialization. As a key component of video surveillance, the intelligent video analytics market is gradually expanding as the technology continues to mature, and is slowly becoming an industry. Especially in China, the trend of intelligent video surveillance has become increasingly apparent.
With the acceptance of the pilot construction of the 22 cities' alarm and monitoring system and the demonstration of the second batch of science and technology strong police demonstration cities in 2008, it marked the successful conclusion of the safe city pilot project. As the main content of the urban security monitoring system as a safe city construction, public security "science and technology strong police" and public security information construction will gradually transition from system construction to operation management stage. In the application stage of the system, how to apply after the large-scale system is completed? How to integrate closely with the public security business and maximize its effectiveness? How to maximize the effectiveness of the system's construction? To this end, the requirements for intelligent video surveillance came into being.
I. Intelligentization Imperative The development of intelligent video analytics technology provides an excellent opportunity for intelligent video surveillance. The intelligent video analysis system extracts and screens abnormal behavior events in the video in real time, and issues early warnings in a timely manner. This changes the passive state in which the traditional video surveillance system can only “monitor†and cannot “controlâ€, and solves the problem of difficult post-accumulation evidence, allowing monitoring. Become more active. Compared with the traditional video surveillance system with faster response time and more powerful data retrieval and analysis functions, the monitoring capability has been greatly improved.
More active monitoring: not only for post-mortem evidence, but also active, real-time analysis of video and timely reporting of suspicious events.
More comprehensive monitoring: Real-time processing of all connected video can be realized, not limited to the TV wall, without missing any suspicious events.
More continuous monitoring: to achieve 7*24 hours of all-weather monitoring, "machine eyes" instead of the human eye to overcome the limitations of human fatigue.
More effective monitoring: Extracts useful key information from a large number of videos and only provides users with problematic videos. The human-computer interaction monitoring method is used to implement the suspicious behavior analysis alarm. The user only needs to confirm and process the video that generates the alarm.
More powerful monitoring: diversification of functional applications, gradually expanding the behavior of automatic identification, can achieve a wider range of applications.
Second, the development of intelligent video analysis technology Intelligent video analysis technology definition Intelligent video (IV, IntelligentVideo) from computer vision (CV, ComputerVision) technology (computer vision technology is artificial intelligence (AI, Artificial Intelligence) one of the branches of research), it It is to establish a relationship between images and image descriptions, so that the computer can understand the contents of the video images through digital image processing and analysis, and achieve the purpose of automatically analyzing and extracting key information in the video source. That is, the intelligent video analysis technology (IVS). :intelligentvideosurveillance).
Intelligent Video Analysis Market Overview As the technology continues to mature, some professional IVS research vendors have emerged around the world, such as ObjectVideo, Vidient in the United States; NICE, Mate, IOImage in Israel; and IOmniscient in Australia. These manufacturers have entered the Chinese market one after another, causing foreign companies to monopolize the domestic market of intelligent video analysis. In the end, because of the difference between its technology and China's national conditions, it cannot really penetrate the Chinese market. This status quo brings challenges to domestic smart video technology research vendors, while also providing a very good opportunity for development. Domestically, professional intelligent video analysis and research manufacturers such as Wen'an, Zhianbang, and Feiruisi have appeared gradually, and related products have also achieved breakthrough applications in safe cities and key industries. There are also some tailor-made solutions in the safe city project launched in full swing. Behavior analysis functions such as fight and hate detection and abnormal run detection are tailor-made functions specifically targeted at urban security monitoring. The timely warning of such illegal and criminal acts has become an effective measure to improve the capability of city security monitoring systems and strengthen technological prevention.
The status quo of intelligent video analysis technology as a key technology to strengthen the application of video surveillance systems - video intelligent analysis technology, has been widely concerned in the industry in recent years, through the analysis of video content, the customer's focus from the The monitoring background is separated, and the parameters such as the direction, speed, and time of the target are correlated with certain behavioral characteristics to achieve the purpose of actively monitoring and defending. It is said that the large-scale promotion and application of this technology will play a significant role in improving the utilization efficiency of the current public security monitoring system, but in reality it has not been effectively promoted, so-called "applause." The author believes that the main reasons for this phenomenon are the following:
First, most of the current behavioral features that can be identified are limited to specific situations. For example, target tracking, cross-border, counting, target loss, object left, etc., are mainly used in relatively fixed application scenarios such as detention centers, prisons, museums, warehouses, factory areas, and subway stations, and in monitoring environments targeting the social level, due to monitoring The complexity and variability of the scenarios have led to a significant reduction in the stability of the monitoring. The intelligent monitoring products that use the accuracy of the alarm events as the evaluation criteria have also highlighted their application limitations.
The second is that the way it is implemented does not fully meet the security monitoring requirements. At present, although there are many different forms of smart products on the market, most of the video analysis applications belong to front-end analysis, that is, they are embedded in cameras or black boxes through DSPs. However, due to the limitations of existing video analysis technologies, the current All of them can only be analyzed for a specific video channel or video channels. It is obviously not suitable for a security surveillance system with thousands of channels at a time; how to adapt to the varied and large-scale monitoring external environment and security equipment Effective integration is an issue that smart video analysis manufacturers have yet to research and solve.
Third, the market price is relatively expensive, because it is much higher than the difficulty of the development of traditional video equipment, making intelligent products generally have high development costs, which is enough to affect the large-scale promotion of smart products. Price may be an enduring topic.
Fourth, the uncertainty of the user's own needs. At present, although the general awareness of smart video in the domestic market has been greatly improved compared to a few years ago, there is still a certain gap between users' expectation and recognition of smart video. On the one hand, users need to fundamentally see their own needs. On the other hand, they must also understand the functions of smart video and the problems that can be solved by practical applications. This also requires a lot of effort from manufacturers, engineers and users.
Third, the future development trend of intelligent video Based on decades of intelligent video analysis technology research manufacturers in the commercial application of continuous trials, I believe that intelligent video analysis technology in technology and applications have the following development trends:
From a technical point of view, in order to enhance the application of intelligent video analysis technology, intelligent video analysis products are truly market-oriented. As an intelligent video analytics vendor, while improving its core algorithm, it will certainly develop in the following directions:
(1) adapt to more complex and changeable scenarios;
(2) Identify and analyze more behavioral and anomalous events;
(3) Lower costs;
(4) More flexible product form.
From the application perspective, it is not difficult to understand the following two points:
1. Depth expansion of industry application requirements The demand for video surveillance in different industries generally has very obvious differences, especially for the application requirements of intelligent video analysis technology, which also determines the specificity of detection behaviors and abnormal events among different industries. With the continuous deepening of applications in various industries and further improvement of security level control requirements, various security areas will face more and more different challenges. Their demand for video surveillance is also becoming increasingly complicated. How can we identify and analyze more behaviors? Has become the intelligent video analysis technology in the process of deepening the application of the industry have to face the problem. Only by combining the actual application of the industry and in-depth understanding of the specific issues of different industries, can we better grasp the needs of users and put the functions of intelligent video analysis technology into practice. This is also the ultimate manifestation of the future industrialization value of intelligent video analytics technology.
2. Flexible Application of Modular Design With the continuous improvement of security requirements, users have invested more in video surveillance systems, and have deepened their application and dependence. A single function or basic function is far from meeting the actual needs of the industry. In the future, for specific users, the advanced functional modules such as perimeter, abnormal behavior analysis, and dynamic tracking will be further applied, making the video surveillance system to be modularized. Ways to expand flexibly on demand. Providing a complete set of intelligent solutions based on industry applications will be the main direction for the development of intelligent video analytics technology.
Fourth, the prospect of intelligent video analysis technology With the "National Emergency System", "Safe City", "Safety Construction", "Technology and strong police" and other major projects in the country continue to advance, the domestic video surveillance market outlook is promising. The application of intelligent video-related products will grow from the relatively concentrated area to various industries as the market size of video surveillance continues to grow. In terms of market demand, the current market awareness of intelligent video analytics is constantly improving. On the one hand, users have been psychologically transitioned from the "what is" to "how to do it." On the other hand, some professional video analysis and research manufacturers are also working to improve the existing core technologies to further enhance and optimize the existing algorithm structure. In terms of function, application and price, we strive to pay more attention to the actual needs of users to achieve the best system product form. As a high-end application for video surveillance, functions such as perimeter detection and object tracking have been successfully applied in various key industries and have gradually shown their power.
For the distance between current user expectations and reality, video analysis research vendors and users are trying to find a balance between functions and applications. How to correctly plan intelligent video analysis, what strategies to use, how to have a clearer understanding, but also need the close cooperation of the entire industry chain, which is the inevitable trend of future intelligent video development.
Since the birth of intelligent video analysis technology in the 1990s, after decades of development, this technology originated in computer vision has been increasingly paid attention by people along with the gradual application of commercialization.
