With the continues progress of video processing, analysis, transmission technology, Monitoring system develops from a pure analog system to the module integration, pure IP surveillance methods, intelligence analysis needs of surveillance system have emerged. The intelligent control technology requirements of security monitoring areas come from a variety of actual needs in specific industrial monitoring, each of the specific monitoring may need certain types of intelligent monitor technology.
The individual needs of the segmented markets, determined that we must pay close attention to the particularity of different systems, and take market as the whole company’s orientation, with sales, market, technology, research and development, product departments closely cooperating with each other, providing customized products and services for the various industries customers to meet their unique needs.
For example, the monitoring industry's traditional big customers - banking. Recently, the banking problem which is most in need of solving in monitoring, is the resolution of the image looking at it superficially, in fact, the ultimate goal is to achieve recognition of human faces and to restore the real scene. Thus extended to intelligent video analysis, we can see that bank monitoring system needs a stable and reliable face recognition function. For the ATM cash machine, except to tell the identity, the bank still needs to protect the expensive ATM equipment, to eliminate the fraud as soon as possible. Blocked face recognition, special action recognition (trailing, patching, etc.) features are ideal for the ATM cash machine on large scale.
Another example is security monitoring, focusing on people-intensive sites, it need to combat "Robbery", to prevent the mass of ******** and so on. In the monitoring points such as squares, stations, pay close attention to the flow of movement, analyze and report the suddenly gathering situations. analysis the sudden human movement on the road, to judge accident cases of the pedestrians in time, it is also a powerful prevention for "Robbery".
As the continues development of monitoring industry, intelligent monitoring products is bound to spread to each industry and profession, and all sectors must and will combine their own characteristics, proposing requirements to intelligent monitoring. Therefore, to thorough study customer needs in different industries, through cooperation between the front end market staff and back-end R & D engineers to complete a unique solution for different systems, only in this way, it can remove obstacles and open up new markets for our company.
Functions and key technologies of intelligent monitoring in different applications area:
Intelligent video analysis technology used in surveillance area has been more than 10 years, but due to the differences of industrial needs, it is still in the process of thriving and constant refining.
Intelligent monitoring technology currently includes several major categories: 1, recognition of people and things; 2, recognition of trajectory of people and things; 3, the judgment and compensation to video environmental impact.
■ Recognition of people and things: The main task is to identify concerned content of the monitoring system, including face recognition, plate recognition, types of vehicle recognition, vessel identification, traffic lights identification, and so on. For recognition intelligent monitoring technology, the most critical requirement is the recognition accuracy. Such as plate recognition, the excellent one can be 95% or 98% currently on the market, so it can better meet the customers’ needs of road monitoring. If the recognition rate is less than 90% It will bring great troubles to managers. Recognition technology, often apply to road monitoring, financial industry and banking, channel management and other industries, primarily to provide identification and classification records and management basises.
■ Recognition and processing of trajectory of people and things: currently divided into many kinds of usages, including a virtual cordon, virtual warning areas, intelligent tracking, population counting, traffic statistics, the appearance and disappearance objects, sudden movement people, suddenly gathered etc. Such kind of technology, in addition to the quantity statistics, generally, it is a judgment for a certain process, once discovered abnormal conditions, such as person getting into the alert area, people sudden gathering at the northeast corner of playground etc. It will send out a warning message to remind the people who is on duty to pay attention to the hotspot. As for quantity statistics technology, the key technical point is to discover the abnormal conditions, and collect statistics. Therefore, it requests for accuracy of the statistical data, to minimize errors. Trajectory recognition processing technologies were influenced largely by actual monitoring scene . The key to such technology is the ability to discover abnormal situations as soon as possible, and need to avoid omission and improve forecasting accuracy. Currently these functions are mainly used in construction of safety city, the commercial security industry.
■ The judgment and compensation to video environmental impact: the impact of the environment including rain, snow, fog and other bad weather, low light level situations at night, camera blocked or displacement, camera jitter and so on. Intelligent monitor technology can achieve comparatively normal monitoring function in the harsh video environment. When the video is not clear affected by the environment , it can find people from the video image as soon as possible, or sound the alarm when the camera is displacement. The key technical points of such functions are that it is able to output intelligence analysis information stablely in a variety of applications, to minimize the environmental impact to video monitoring. This feature has general adaptation, and more than 80% of the monitoring points have the potential demand for such functionality.
Status and prospects of the industry development:
Intelligent monitoring technology is a hot concept in monitoring industry currently, but the individual needs of different industries have made very high demands on the intelligent monitoring technology. Customers from every industry, and even each project's specific application environment, have slightly different requirements for intelligent monitoring.
Market demand is the biggest industry booster, intelligent monitoring is doomed to become mainstream in monitoring market. With the cooperation of markets and staffs, and through repeated trial and experience, our company believe that we will continuously meet the needs of industry segments, truly achieve in flexible application of the standard configuration and modules, continuously improve the universal and specific environmental adaptability of the technology to customized products and services for various industrial customers, and become the industry leader in intelligent surveillance.
