Intelligent surveillance video analysis to lead thReading number of times [224] Time :2010-1-28
Video surveillance technology is towards digital, network-based, intelligent direction, networking, and intelligent based on digital. The intelligent "three" of the highest state. Interpreted by the visual system into automatic interpretation of video monitoring technology leap in technological development is a security necessity. The current situation will greatly facilitate this development process, in particular, intelligent trend more dramatic. The face of an increasing number of cameras on the market, but do not have enough manpower to conduct monitoring; even through real-time monitoring of human conduct, or can not be effectively out of the incident identified; traditional video surveillance can only be a passive tool for ex post facto view the market an urgent need to have intelligent video analysis of events hidden surveillance system for early warning, pre-empting and purpose. So what is Intelligent Video Analysis of surveillance technology?Intelligent surveillance video analysis technology is also known as "behavior monitoring technology", meaning the use of intelligent video analysis algorithms, using computer vision within the framework of the objectives of the specific conduct of analysis and extraction, when found, in line with certain rules of behavior (such as the directional movement, cross-border, loitering, legacy, etc.) occurs, the automatic signal to the monitoring system alerts and take corresponding measures.
Intelligent surveillance video analysis technology is also part of a pattern recognition technique, it is through the design of certain computer algorithms, from the video analysis, extraction and recognition of the characteristics of individual motor behavior, so that the computer determine what these individuals had some behavior, and thus can determine whether such acts, subject to certain rules, whether "certain type" behavior, and these types of acts should remind the monitoring personnel pay attention to "suspicious behavior", so that when the computer they found the "suspicious behavior" when you can for immediate alarm, free from human intervention and to determine to achieve to make the computer "instead of" people monitoring that is achieved "automatic monitoring" or "intelligent monitoring." More images from the point of view to explain a little, surveillance camera systems and video transmission technology to solve the "eyes" of the issue so that staff can monitor the situation at the scene did not live through the camera to see the scene of the scene, and this Field also due to advances in transmission technology out of the geographical constraints, even thousands of miles away can be achieved; and intelligent surveillance video analysis technique to the monitoring system with the "brain", so that the machine can replace the people to a certain extent, at any time monitor the video, no longer by hand at any time to monitor the video.
Intelligent surveillance video analysis technology is a new technology, is a monitoring system developed to a certain extent the natural market demands. Everywhere in modern society, surveillance, monitoring system, extensive use has led to the sea surveillance video source to quantify, but the limited staff that led people to not take advantage of these surveillance video information, so that a monitoring system to a large extent reduced the subsequent " Video query system, "is not only a waste of massive amounts of information and data, but also did not fundamentally solve the" real-time monitoring, real-time response "The purpose of this contradiction a long time, but not prominent.
Intelligent video analysis the trend of future development?
Intelligent video analysis technology and products now in the high-end security surveillance market, has many years of application. At the airport, prisons, military bases and other large-scale infrastructure monitoring and control of both success stories. However, and other emerging technologies, video analysis will take some time to truly enter into the primary and secondary surveillance market. In primary and secondary market surveillance and video analytics products is not the main product is well-recognized fact, then the video analysis product in the end it just takes a long time to become mainstream? In other countries, many industry users may tell you that video analysis has been the mainstream products, because many banks and supermarkets already in use. Others might say, and now the technology is not mature at the same time prices have not dropped so that the agent has the level of profit margins. Manufacturers have entered the mainstream market, they provide to the market is simplified to adapt to the needs of medium and small projects program. Video analysis of the real mainstream market, not in those small and medium market almost saturated. But the trend is undeniable, the price getting lower and lower, the video analysis are gradually entering the mainstream market.
The domestic video analysis technology products is still at an early stage, while the foreign mature products have also entered the domestic market, seize the opportunities, then, where several aspects of domestic products should be to seek development?
1, the market demand: capacity from the market, although currently the average level of video surveillance technology is still relatively low, but because of the economy continues to develop, eastern and western regions and uneven development, and the market capacity is huge, therefore, intelligent video analysis monitoring technology The market space is extremely huge and long-term demand for a process, is still by far the initial stage, from the point of time and capacity of view, there is still enough time left to domestic business R & D and market intellectual property products, and be able to pin with research, without a huge investment in the short term funds, thus reducing development risk.
2, Price: Due to the different levels of economic development and for the high-tech products, costs are different, has now entered a mature domestic market, foreign surveillance video analysis technology products remained at a high price level, although the capacity of domestic market prices low and competitive and for the purpose to seize the Chinese market, has been a downward trend in prices, but the higher price level will continue for some time, this is the first to introduce low-end products of domestic enterprises to seize the market provide some opportunities.
3, the product forms: mature foreign products in foreign markets to gain practical engineering applications, forming a relatively mature product shape, but also mentioned earlier, this product form (including the system as a whole structure of form) may not be able to fully meet the domestic market, demand and usage, which for domestic enterprises to adopt differentiation strategy, launched for the domestic market demand and usage habits of products possible.
4, other factors: the practical engineering application involves not only the product degree of maturity, but also involves a number of other factors, such as in the domestic market to sell the products through the relevant identification (such as 3C, software, registration, etc.), or some domestic users in the use of security surveillance products, the product specific requirements (such as the priority to the use of domestic products, or in some government troops and other units of the high-level security projects is completely not allowed to use foreign technology requirements, etc.), these factors help domestic enterprises to promote Sales of own products with independent intellectual property rights.
Intelligent video surveillance products to fill the gaps ESHT
Beijing Tomohiro Hong Technologies Co., Ltd. with 16 well-known doctor 4 authoritative institutions of cooperation, after three years of independent research and development, has successfully developed ESHT series, breaking the international monopoly to fill the domestic gaps in the field of video surveillance. Through schools, offices, underground coal mines, subway, the practical application of the detention center to achieve the Olympic facilities, intelligent perimeter security, the Olympic anti-terrorism security of "China" of applications.
ESHT series of products are based on front-end DSP completely embedded intelligent visual analysis equipment, no back-end PC for processing; can detect ultra-slow or ultra-high-speed moving target; detect sudden invasion or in need of care goals. Installation is very easy to set up, 5 minutes to complete set up, input normal use. When a target intrusion, the device auto-detection, analysis and alarm to alert security personnel on-site investigation. Traditional video surveillance system only need to increase the ESHT intelligent visual analysis equipment that can be upgraded to intelligent video surveillance systems. Easy simple upgrade method can save a large amount of monitoring costs. Detection, identification, analysis and alarm equipment are all done automatically, without manual operation. When setting a good testing rules, as long as the anti-region events triggered rules, the machine can be pop-up warning window, and can trigger the alarm linkage device to remind the security personnel to confirm processing.
New technologies, in particular, there is a revolutionary technology takes time and nurturing and patience. Fastball when China first entered the price of an expensive tens of thousands of pieces, and now fast ball market is very mature, domestic market, the fast ball has been more and more recognition. With the intelligent monitoring technology matures, the market awareness of the upgrade, as well as traditional monitoring of existing drawbacks of market development can not be applied, I believe that in the near future, intelligent video analysis will be a rapid development.
