High-definition highlights the trend of intelligent transportation industry

Intelligent transportation is a service system based on modern electronic information technology oriented to transportation. Its outstanding features are the collection, processing, distribution, exchange, analysis, and utilization of information as the main line, providing a variety of services for traffic participants. With the development trend of high-definition urban security industry, the trend of high-definition intelligent traffic is becoming increasingly prominent. So, what are the applications of HD Intelligent Transportation? What are the development trends of future high-definition intelligent transportation?

High-definition highlights industry trends

The high-definition front-end video capture will certainly be a trend in the future. The traditional system uses analog standard-definition imaging technology with a maximum resolution of 768×597 and only 450,000 pixels, and the definition is obviously insufficient. In addition, the linear imaging of the simulation system is also faced with problems such as poor image layering and poor contrast. At the same time, due to the limitation of resolution, the image field captured by analog SDTV cameras is small, and a camera is often unable to take into account the details and the panorama. As a result, it is impossible to clearly capture the details of people, vehicles, and objects, as well as the status of the ride. The direct result is that when businesses such as criminal investigation and law and order require tracing of the appearance of criminals, details of vehicles involved, and the appearance of the driver of the vehicle, they appear to be Powerless.

Using high-definition camera imaging technology (usually 2 million, 5 million pixels or higher resolution HD cameras), can greatly improve the quality of captured images, not only can clearly capture the details of people, cars, objects, but also can provide high The quality of the panoramic image, and can record a larger range, a wider range of information within the scene to meet the criminal investigation, security, traffic police and other business departments. Therefore, the high-definition video surveillance system has become a hot spot in the current industry development.

High-definition products infiltrate high-end users

HD video surveillance has become prominent in the mass industry application market and will continue to penetrate into industry applications and high-end users. The future monitoring system, high-definition video surveillance will be integrated with the traditional analog-digital system to build a security system platform that can coexist and interconnect with each other to meet users' multi-level applications. Different industries and different occasions have different requirements for image clarity. It is important to see if a person’s facial features can be clearly seen in a busy downtown area. It is very important to see the license plate of the vehicle. In the lobby of a high-rise building, there are crowded entrances and exits. High-speed cameras can greatly increase the application value of the system, the entrance and exit of parking garages, highways, stadiums and other occasions, and play an active role in the supervision and management of urban public order. However, at present, HD cameras are not popular, but they have just begun. This requires the development of the market and the promotion of high-definition cameras to achieve the goal of high-definition, allowing users to see more clearly and further.

At present, most of the intelligent traffic cameras such as bayonet capture, speeding capture, and electronic police are standard-definition products, and high-definition products are gradually replacing standard definition products everywhere. Related manufacturers are facing a "big reshuffle" of products and require manufacturers to seize this opportunity to focus on intelligent transportation as the key support industry. Whether it is a high-definition network camera or an analog high-definition camera, it will be useful in the security market in the future. Therefore, in the near future, the entire intelligent transportation industry will enter real high-definition and digitalization.

HD Intelligent Transportation Products

High-definition mounts and electronic police have been proposed for several years, but they have only been used for the past two years. The system not only has industrial-control high-definition products, but also has embedded high-definition products. Through unified platforms, various front-end data can be uniformly processed. The platform uses websphere as an application server and uses oracle as a database, completely surpassing the requirements of the Ministry of Public Security for system security performance.

1, HD radar trigger speed capture system

The front-end capture system adopts the Doppler effect detection technology of narrow-wave radar, which not only has various bayonet functions, but also provides a speed penalty function. High-definition industrial-grade CCD megapixel capture camera is used to independently complete the capture of all passing vehicles and the triggering of smart strobe lights, and the captured images are transmitted to the center through the network. The license plate recognition host computer identifies and superimposes the information and will process The pictures are sent to the central management server and database server. All intersection capture records are managed centrally by the central server. Each management station can perform real-time query management of the captured images of each intersection, and use a standard definition camera for real-time monitoring in each direction. Video.

2. High-definition electronic police system

Using 2 million CCD HD network cameras, using pure video capture, each camera monitors two to three lanes. The HD network camera automatically shoots three panoramic (and close-up) pictures of illegal vehicles, and at the same time, the LED strobe lights are used to fill light to ensure that the images are clearly available. In order to ensure that the photos taken can be used as a basis for traffic police enforcement, three high-resolution panoramic (and close-up) pictures that reflect the dynamic operation of the vehicle will be continuously saved, three of which correspond to the vehicle's unpressed stop line during the red light, and the vehicle During the red light, it is pressed on the parking line or goes through the parking line, and the vehicle continues to travel after passing the parking line during the red light. All processing results are transmitted through the network to the center of the red light processing host for storage, information overlay, storage information automatically uploaded to the server management system through the transmission system (can manually control the download to the relevant storage media), apply computer processing.

3, other programs

Some red light systems use high-standard cameras (standard definition analysis of vehicle trajectories, high-resolution capture pictures). This kind of system is not a pure high-definition system, but it also has certain advantages. After all, standard definition video requires low requirements for host resources, storage, and transmission. There are also high-definition CMOS cameras, but it will cause smearing in the bayonet applications, and the requirements for lighting at night are more demanding than those of CCD high-definition cameras, and often require high power fill light to increase image quality and reduce image noise. problem.

The prospect of HD traffic

At present, high-definition video surveillance has become prominent in the mass industry application market, and will continue to infiltrate industry applications and high-end users. The future security system, high-definition video surveillance will be integrated with the traditional analog-digital system to build a security system platform that can coexist and interconnect with each other to meet users' multi-level applications. Different industries and different occasions have different requirements for image clarity. It is important to see if a person’s facial features can be clearly seen in a busy downtown area.
