As we all know, intelligent transportation is an inevitable choice for the development of the transportation industry and a revolution in the transportation industry in the 21st century. Of course, the application of security technology and products in intelligent transportation is mainly based on video surveillance. With the introduction of new standards for intelligent transportation 496 and 497, it has also put forward higher requirements for the functions of bayonet and electronic police in functions, applications, scenarios and storage. In the evaluation of this program, Hikvision will bring more practical and forward-looking intelligent transportation solutions to users under the premise of relying on the new standards.
First, the trend of intelligent traffic technology cross and integration is obvious
In the process of urbanization, road traffic in most cities in China is facing a series of problems such as “junction accidents, traffic congestion, and parking difficultiesâ€. How to strengthen traffic management, solve and alleviate these traffic problems, and provide accurate, timely and reliable travel information services to the public is a core issue in the traffic management department, including on-site law enforcement, accident handling, road network management, and special service. Mission, transportation services, inspection and control.
Around these traffic core management functions, local traffic control departments vigorously promote the construction of intelligent transportation systems (including traffic signal control, bayonet, traffic video surveillance and many other intelligent traffic subsystems). With the construction of intelligent transportation systems becoming larger and larger, the trend of technology intersection and integration between equipments and systems is becoming more and more obvious, and industrial standardization work is steadily “going forwardâ€. For example, the construction of bayonet needs to follow the “General Technical Conditions for Road Vehicle Intelligent Monitoring and Recording System†(GA/T497-2009), and the construction of electronic police needs to follow the “General Technical Conditions for Automatic Red Light Recording System†(GA/T496-2014), video Transmission needs to comply with the "Technical Requirements for Information Transmission, Exchange, and Control of Security Surveillance Video Surveillance Networking System" (GB/T28181-2011).
Second, re-start, speed up the layout of intelligent transportation
As a security integrated solution provider, Hikvision has leading video surveillance technology. After the launch of the fist-type product in 2014, the traffic light control system, the entire road intelligent transportation product line has been perfected. It is a veritable provider of intelligent transportation solutions. In 2015, Hikvision re-started, accelerated the layout of intelligent transportation, and promoted the rapid development of the domestic intelligent transportation industry.
1, composite detection bayonet capture vehicle details
The traditional bayonet adopts virtual coil detection. Hikvision's bayonet adopts full-screen analysis and multi-technology composite detection, which can realize forward and reverse detection and capture, and can distinguish between motor vehicles, non-motor vehicles and pedestrian classification detection and capture. This includes automatic capture and capture of common violations such as retrograde, pressure line, lane change, and illegality.
For the capture recognition of the bayonet, the current business point not only pays attention to the illegal behavior, but also pays more attention to the details presented in the illegal behavior. Based on these details, we can do more business applications, such as deck analysis.
Hikvision's bayonet devices support diverse identification, such as vehicle sun visors, 11 body colors, more than 1,000 vehicle sub-brands, and 7 models. In addition, we are also developing a function that automatically recognizes the driver's call and does not wear a seat belt. The purpose is to expand the image discrimination and retrievability through the retrieval and recognition of these picture details, strengthen the retrieval of vehicle violations and vehicle identification in the system, improve the running speed of the system, and conduct more detailed screening of the illegal behavior of the vehicle. .
2, the electric police bayonet linkage to meet new standards, new business
The new GA/T496-2014 standard is fully compliant with the requirements for face pixel requirements (50 & TImes; 50), which on the one hand enhances the user's requirements for front-end camera pixels, and on the other hand improves system linkage. Requirements. In the process of law enforcement, the traffic police found that there was a phenomenon of “buying points and selling pointsâ€, so the traffic police are now stepping up efforts to crack down on such behavior.
Hikvision's electronic police system has been catering to the traffic police's new business. It has achieved the integration of the electric police and bayonet system, and has increased from six previous vehicle violation photos to six. The six photos are superimposed by the terminal server to achieve the purpose of law enforcement for face forensics. The new standard also requires that the second picture captured must effectively identify the license plate. Since the second picture is captured, the distance traveled by the vehicle is farther away, which also puts higher requirements on the system and camera pixels.
In response to the new GA/T496-2014 standard, Hikvision has launched a 3 million-megapixel camera model in which a 6-megapixel HD camera captures two-lane and 3-megapixel HD cameras to capture two-lane HD images. The high-pixel front-end device can provide a higher level of law enforcement and evidence for the back-end intelligent analysis and processing.
In addition, the new e-police standards have placed more demands on video and capture behavior, including traffic parameters. The GA/T496-2014 standard requires that the front-end recording must be kept for 7 days. In the past, the SD card was used to store the video on the front end. After our calculation, the front-end four-way intersection will meet the standard requirements, and the total data will reach 2.8T every 7 days. However, existing memory cards cannot meet this requirement, so applications of front-end storage devices must be enhanced.
