With the development of the market, it has become an inevitable trend to change the SD card to HD. At present, the high-definition security security bayonet system uses more than megapixel camera, while the traditional SDTV bayonet uses more than 40W pixel analog camera, can only take special photos. After several years of development, the development of high-definition cameras has reached 200W pixels, and even 500W pixels. And 3 or 4 lanes of road monitoring only need to set up a monitoring point, equipped with a high-definition camera, you can take pictures of all the surrounding vehicles clearly. The development of the electronic police as an indefinite development direction has obvious technological advantages. However, industry application problems still exist.

Electronic police highlights the advantages

At present, there are many electronic police systems used in the society. In principle, there are two major categories: one is the digital camera electronic police and the second is the video electronic police system. In terms of performance, digital cameras are far less than video electronic police. The video electronic police system is described below.

The use of advanced video detection technology and license plate recognition technology has greatly improved the technical content of the system, greatly reducing the system's miss rate and miss rate; using advanced virtual detection technology, without having to break the road buried sensors, sensors Such equipment reduces project investment; it not only records illegal vehicles, but also records illegal locations (junction names), illegal red light time (accurate to second) and other information, providing a wealth of information for law enforcement.

Using the combination of panoramic and close-up methods to make the captured information more adequate, the panoramic picture can show the opposite red signal sign, the vehicle does not pass the parking line panorama, the vehicle violates the illegal process of crossing the parking line, and the close-up picture can fully provide the license plate number of the illegal vehicle. , models, vehicle colors, etc., provide sufficient evidence for law enforcement; direct superimposition of video information on pictures. Guaranteed the unity of picture and character information, internal personnel is difficult to tamper with and persuade; panoramic camera uses high-performance color camera specially designed for traffic characteristics, close-up camera uses high-definition integrated color camera, can provide high-quality illegal pictures And a wide range of shooting; system uses high-definition image acquisition technology, image clarity, color reproduction is good.

High-definition to clear

In fact, the traditional SD electronic police has limited pixels, the pictures are not particularly clear, and the night photography is even worse. Therefore, the automatic recognition rate of the license plate of the bayonet system has not been high. The high-definition security bayonet system can not only see the license plate, but also make use of the high pixel advantages of high-definition cameras, making the image information more abundant. The pictures captured can clearly reflect the facial features of the driver and the co-driver's seat, which is conducive to the public security department's secondary investigation of suspect vehicles, and solves the problem of suspect vehicles removing license plates or decks and other evasion checks.

Traditional standard definition cameras can only estimate one lane when taking pictures and the pictures taken are not very clear. HD cameras, in addition to capturing panoramic images, clearly identify the vehicle type, body color, cargo, and location.

It is reported that many companies have already launched the HD security security bayonet system. The front-end uses a high-definition network camera, uses a camera to work in two lanes, and the captured data is converted into manageable data after license plate recognition and sent to the back-end platform. The time, date, speed, length, and length of each vehicle. The number of license plates, the liveness of the cab, etc. are all recorded. Once an accident occurs, simply input the time zone, license plate number, vehicle type, etc. to easily query the data for a certain period of time.

Traffic applications still exist

E-police provides grounds for road traffic command, improves urban traffic, eases traffic jams, and provides reference for scientific traffic planning. Electronic police has become an important part of road traffic management systems, making road traffic management more scientific and rational, technically Improve the performance of traffic management. However, the daring and heroic electronic police have lived an All-Star-like life. In fact, there are still certain problems in the technology.

1, product compatibility and stability is poor

The degree of integration of the electronic police monitoring system is relatively high, the compatibility and stability of the design to each specific product, and the multi-supply channel of the system equipment configuration make the operational instability factors of specific details more. Because different manufacturers have different technologies and different solutions, data interfaces, video formats, video playback software, video compression formats, transmission media, data transmission methods, and central management platform software of different manufacturers' electronic police monitoring system equipment are all different. . Between various devices and devices, problems such as incompatibility, inability to integrate, etc. often occur.

2. The lack of a unified standard for electronic police monitoring systems

Whether it is the electronic police monitoring system or the entire security industry, “standard absence” has always been one of the important factors that hinder the development of the industry. There is no rule. Not a circle. Presumably, a set of standards and systems is the inevitable choice to regulate the market and expand operations. When the user's needs are not clear, the products produced by the manufacturers according to their own understanding will have more or less problems in use. If a complete set of bidding requirements is met, the errors between the two can be resolved.

3, weak management products after sales nobody cares

The electronic police monitoring system is not a serious problem after the sale, and the electronic police monitoring system is a category of weak electricity. There are many unstable factors in the electronic products themselves, and the monitoring equipment in many places often has problems and cannot be solved in a timely and effective manner, resulting in many places. The equipment became furnishings. This is a problem of communication between Party A and the manufacturer. It should be solved by upgrading the quality of maintenance services in the later period.

4, intelligent analysis of weak mobile monitoring can give power

For the transportation industry, the electronic eye shoulders the task of monitoring road information and shoulders the task of law enforcement. Such as the limit of time into the ring, illegal parking, forced to account for, etc., these are the need for intelligent analysis to achieve. In order to better implement the relevant norms and guidelines for traffic safety in urban roads, the addition of mobile monitoring and detection can improve the efficiency of electronic police.

If the electronic police surveillance system can easily overcome this four-fold barrier, it will be incalculable compared to the future market prospects. The electronic police as a star show in the transportation field will have different new products and new technologies every year. The transportation industry not only has the most handsome traffic police, Meng Kunyu, but also has an all-star lineup of "electronic police."
