Urban security keeps warming up

With the rapid economic construction and rapid economic development, the rapid growth of existing motor vehicles and drivers and the relative lag in urban road information management construction have caused the current traffic management model to be incompatible with the rapidly increasing traffic demand. It has brought severe challenges to the public security traffic management department. Congested traffic, increased number of parking, and rising traffic accidents not only affect the development of economic construction, but also impede the daily life of the people. This has triggered the strong demand for security applications in public transport systems in cities. High-definition intelligent traffic detection equipment has become a trend in urban traffic management and construction.

Recently, the Central Government Office and the State Council General Office issued the Opinions on Strengthening the Construction of Public Security Prevention and Control System, which focused on strengthening the public security prevention and control network of the public transport system, establishing and improving the command and security mechanisms, and improving the morning and evening peaks. Concentrated workplaces have important service and work mechanisms to reduce blind spots and blind spots, and improve the dynamic control capabilities of the society.

The urban public transport system has the characteristics of large people flow and high mobility. In such areas with dense population, complicated personnel, and many moving objects, an emergency command system is needed to ensure its safe and stable operation. The monitoring system is undoubtedly the most important part of it. It is like the human visual and brain analysis system. It can play a role in analyzing and judging in advance and collecting evidence afterwards. It has become an important means to assist the public security department in cracking down on illegal crimes and maintaining social stability.

Ipcam has become the mainstream application method in the current surveillance industry. With the high-definition network camera, it can obtain clearer video images and a wider viewing angle. As a part of the intelligent monitoring system - face verification (identification) technology, it can directly help the user to extract the most useful information from the video screen - "human" information, which will greatly enhance the monitoring system. Value, so that the monitoring system is no longer "dumb" to go video, and let it "recognize people" is a very good application model.

The HD video face recognition management system selects about 20% of the key video points, performs local face capture and feature extraction, and creates a long-term face snapshot library in real time. At the same time, two main functions are deployed in the back-end: real-time blacklist control and face static retrieval. In this way, in practical applications, real-time deployment of the focus of attention on key occasions can be achieved. Once attention is paid to the appearance of human faces on these critical occasions, the back-end will immediately call an alarm to remind human intervention. In addition, the face static search can also be used to detect the need for case detection. It uses the historical photographs of the suspects to search widely in the face capture library to piece together historical traces to predict and trace their direction of action.

The traffic volume of public transport systems is large, especially in key monitoring areas such as: car/train stations, airports, docks, customs gates, urban arterial roads, and plazas. The emergency protection measures are very important. The intelligent monitoring system has become a bus monitoring system. One of the best choices of the system is to realize the dynamic face capture and recognition of the face in the original high-definition monitoring system. In combination with the set blacklist, each face that appears in the camera picture is identified and an alarm message is automatically sent to the user. Related department or personnel. In the vast sea of ​​people, as long as it is the face that appears on the surveillance camera screen, the person can be found in a short time by comparison, providing a great weapon for the police to find someone and hunt down.
