Label: Electronic Police Dynamic Detection
This article refers to the address: http://
The electronic police system adopts video dynamic detection technology, visual recognition technology, computer image processing technology, communication technology and automatic control technology, database technology, and uses high-definition CCD camera as detection sensor to process dynamic traffic video images in real time. The system can overcome the disturbances of weather, pedestrians, bicycles, environmental background changes, etc., so as to realize the supervision and detection of the driving behavior of motor vehicles, and have the functions of road condition image monitoring.
Electronic police features and advantages
At present, there are many electronic police systems used in the society. There are two main categories in principle: one is digital camera electronic police, and the other is video electronic police system. The digital camera is far less than the video electronic police in terms of performance, etc. The video electronic police system is described below.
1. Using advanced video detection technology and license plate recognition technology, the technical content of the system is greatly improved, and the system's error rate and missed rate are greatly reduced.
2, the use of advanced virtual detection technology, without the need to break the way to embed sensors, sensors and other equipment, reducing engineering investment.
3. Not only record illegal vehicles, but also record illegal locations (names of intersections), illegal red light time (accurate to seconds) and other information, providing a rich information basis for law enforcement.
4, the combination of panoramic and close-up, so that the capture information is more adequate, the panoramic picture can show the opposite red light signal sign, the vehicle does not pass the parking line panorama, the vehicle violates the illegal process of the parking line, close-up pictures can fully provide illegal vehicles The license plate number, model, vehicle color, etc., provide sufficient evidence for law enforcement.
5. Directly superimpose the video information characters on the picture. It guarantees the unification of pictures and character information, and it is difficult for internal personnel to manually tamper with and is convincing.
6. The panoramic camera adopts a high-performance color camera specially developed for traffic characteristics. The close-up camera adopts a high-definition integrated color camera, which can provide high-quality illegal pictures and a wide shooting range.
7, the system uses high-definition image acquisition technology, the image is clear, color reproduction is good.
é—¯Red light electronic police system application
1) Using the dynamic video detection trigger technology, in the red light state, the capture and license plate recognition of the red light vehicle is completed, and the illegal time, location, driving direction, red light time length, and the parking line of the illegal vehicle are accurately recorded and stored. Red light moments, illegal license plate pictures and panoramic pictures.
2) The picture of the illegal vehicle captured is a panoramic view of the vehicle license plate and two consecutive violations of the vehicle. The captured vehicle violation pictures can clearly and completely record the model, body color and license plate number of the illegal vehicle.
3) The center recognizes the license plate of the illegally captured vehicle, and the identified number plate automatically generates a library of illegal license plates for further confirmation and processing by the operator.
4) Select industrial color camera, high definition, low illumination and good stability; the company's self-developed camera control technology enables the camera to capture different weather and light environment effects, so that the system can work around the clock.
5) At night, the self-developed LED fill light is used as an auxiliary light source for capturing, so that the license plate number captured at night is clear.
6) Under the condition of communication, the combination of software and hardware can automatically monitor the normal operation of the system. At the same time, the timing report and the emergency report are used to report the situation to the remote command center, so that the central duty personnel can monitor the normal operation of the system more conveniently and effectively.
Digital currency transactions allow users to convert existing digital currencies into other digital currencies. The entire transaction does not involve any legal tender. Because of the relatively loose regulation, the mainstream digital currency trading platform also opened this function.Digital Asset Exchange (DAE) is a platform for matching transactions between digital currencies, digital currencies and legal currencies. It is the main place for encrypting the circulation and price determination of digital currency transactions.
Compared with traditional stock exchanges, digital asset trading platform not only matches transactions, but also plays the role of market maker and investment bank. The role of the market maker in the trading platform can increase the liquidity of the market, and the trading platform can earn the transaction price difference. The role of the investment bank of the trading platform is to provide services such as issuance and underwriting of digital currency, from which the trading platform collects money fees, or collects deposits in the form of community voting of the trading platform.
