The present invention relates to a traffic violation vehicle monitoring system, and more particularly, the presence or absence of a vehicle driving abnormally on a road with an outflow ramp (egle neck), such as a high-speed road or a dedicated road, is captured by a fixed camera. After checking through the image, if there is a vehicle, it controls the vehicle detection camera (Progressive Camera) to acquire the image of the license plate of the vehicle, makes the database of the acquired image data, and transmits it to the control center. An outflow ramp control system using image recognition to issue a penalty notice.

Spill ramps exist on highways, exclusive roads, and high-speed national highways. The outflow ramp is formed to be able to enter at about 100-300M in front, and when there are many vehicles exiting through the outflow ramp, the vehicle may be delayed to the main line.

Thus, vehicles must strictly exit the lanes and exit through spill ramps, but some drivers may cause traffic jams because they will cut straight into spill ramps after moving to the front of the spill ramp. This situation is so severe that the police department is also focusing on such interrupted vehicles, but there is also a problem that there is a limit to the crackdown due to lack of manpower.

In addition, the driver of the vehicle that normally enters through the spill ramp due to these interrupted drivers are injured in good faith, and other drivers who see it also have another problem that the basic order consciousness is broken.

Therefore, an object of the present invention is to solve the above problems, install a low-cost fixed camera and a low-cost vehicle detection camera in the outflow lamp, to check the violation vehicle through the fixed camera, through the vehicle detection camera After photographing the license plate of the violating vehicle, this will allow the owner to issue a penalty notice, thereby reducing the initial installation cost and reducing errors in tracking the violating vehicle.

It is another object of the present invention to prevent a vehicle delay caused by an interrupted vehicle by preventing entry of the vehicle interrupted by an outflow lamp to induce a smooth traffic flow.

Still another object of the present invention is to prevent waste of manpower by cracking down on violating vehicles through a camera, and to crack down on violating vehicles efficiently.

It is another object of the present invention to enlighten the driver's consciousness by establishing a traffic order by cracking down on traffic order violations such as interruption.

1 is a schematic view showing the configuration of an outflow ramp control system using image recognition according to the present invention, Figure 2 is a view showing the installation of a fixed camera and a vehicle detection camera of the outflow ramp control system using image recognition according to the present invention It is an exemplary diagram showing.

1 and 2, the spill ramp control system 100 using image recognition according to the present invention includes a fixed camera 110, a vehicle detection camera 120, a monitoring server 130, and a control system. It consists of 200.

The fixed camera 110 is installed near the outflow lamp and photographs a certain area. Here, the stationary camera 110 is installed around the boundary lane of the entry lane of the outflow ramp and the driving lane of the main line to photograph only a specific area.

Vehicle detection camera (Progressive Camera) (120) is installed in the adjacent position of the fixed camera 110, when the alarm signal (Internal Alarm) is transmitted from the monitoring server 130, while tracking the vehicle at the same time to shoot and monitor the image Send to server 130. The reason why the two fixed cameras 110 and the vehicle detecting camera 120 are used here is that when one vehicle is used to determine, track, and record a violation of a vehicle, it is very likely that a user may miss a shot of a violating vehicle. If you use a single camera with both of these functions, you need high-speed zooming and pan / tilt functions.

The monitoring server 130 receives an image captured by the fixed camera 110 and compares the previous image with the after image, and generates an internal alarm signal when a moving abject occurs in the two images. Output to the detection camera 120. In addition, the monitoring server 130 compares the image captured by the vehicle detecting camera 120 with a reference image signal, and converts the image transmitted from the time point at which the license plate of the vehicle can be photographed into image data and stores the data into an internal storage means (Flash ROM). After recording in (not shown), it is transmitted to the outside through the digital service unit (DSU) 131 again, and when the transmission completion signal is received from the outside is configured to delete the image stored in the internal storage means. A modem or the like may be used in place of the DSU 131, but the use of the DSU is preferable for high-speed data processing. The image data here also includes the image, the location of the violation, the time and date.

The control system 100 stores the image data transmitted from the monitoring server 130 and determines the vehicle number using the image data, and then communicates with the collective modem 210 to transmit the penalty receipt to the owner through the vehicle inquiry. An operating terminal computer 220, a database server 230, a vehicle inquiry machine 240, a computerized information management server 250, and a printer 260 are configured.

The collective modem 210 receives image data transmitted from each DSU 131 of several monitoring servers 130 in each region, and the communication operation terminal computer 220 operates the collective modem 210. When the transmission of the image data from the DSU 131 is completed, the reception completion signal is output to the DSU 131.

The database server 230 stores image data transmitted through the collective modem 210.

The vehicle tracker 240 identifies the vehicle number using the image data stored in the database server 230 and inquires the vehicle track using the identified vehicle number. Here, it is preferable that the collective modem 210, the communication operating terminal computer 220, the database server 230, the vehicle inquiry machine 240, and the printer 260 are connected by LAN or WAN.

The computer information management server 250, when a vehicle inquiry request is input from the vehicle inquiring machine 240 through the router 241, inquires the vehicle information of the corresponding borrower among the databaseized data, and then inquires the vehicle information inquired by the router 251. The vehicle is transmitted to the secondary query 240 through. Here, the computer information management server 250 refers to a server installed in a place such as the National Police Agency, a computer-related affiliated agency.

The printer 260 outputs the penalty notice through the vehicle track sent from the vehicle tracker 240.

Hereinafter, the operation of the spill ramp control system using image recognition according to the present invention will be described in detail with reference to FIG. 3.

3 is an operation flowchart for explaining a method of controlling by an outflow ramp control system using image recognition according to the present invention.

Referring to FIG. 3, first, the fixed camera 110 continuously photographs an image, and the photographed image is transmitted to the monitoring server 130 (S10).

Then, the monitoring server 130 compares the threshold value between the two images by comparing the previous image with the previous image using the image transmitted through the internal motion detecting program, and if there is a moving object, the threshold value is different. That is, since an event is generated (S20), the monitoring server 130 generates an internal alarm to operate the vehicle detection camera 120 (S30).

The vehicle detection camera 120 which receives this signal tracks the vehicle and simultaneously photographs the violation vehicle (S40).

Then, the monitoring server 130 compares the size of the image captured by the vehicle detecting camera 120 with the reference size (S50), that is, when the license plate size of the vehicle is at a certain size or more from the vehicle detecting camera 120 Record the captured image (S60, S70).

When recording of the image is completed, the monitoring server 130 transmits the image data to the database server 230 of the control system 200 through the DSU 131 (S80), the database server 230 is the transmitted image Data is stored in a database (S90, S100). On the other hand, the communication operation terminal computer 220 transmits a reception completion signal when the transmission of the image data from the monitoring server 130, the monitoring server 130 receives this signal deletes the image data stored in the internal storage means . Here, the monitoring server 130 continuously transmits the image data to the control system () if the reception completion signal is not transmitted due to a line error or a communication failure. Here, the reason why the monitoring server 130 deletes the image data stored in the internal storage means is to always retain the storage area.

When the image data is transmitted from the monitoring server 130 and the storage is completed, the database server 230 transmits the stored image data to the vehicle inquiring unit 240, and the vehicle inquiring unit 240 uses the transmitted image data. After identifying the vehicle number, the identified vehicle number is transmitted to the computerized information management server 250 through the router 241.

Then, when the vehicle inquiry request is input from the vehicle inquiring unit 240, the computer information management server 250 inquires the vehicle information of the corresponding borrower among the databaseized data, and the vehicle information inquiries are obtained through the router 251. Transmit to 240 (S110).

When the vehicle inquiry is completed from the vehicle tracker 240, the printer 260 outputs a penalty notice using the vehicle information transmitted from the vehicle tracker 240 (S120).

Therefore, by using two low-cost cameras to efficiently photograph traffic violations, it is possible to reduce initial installation costs and to reduce errors when tracking off violations.

As described above, according to the outflow ramp control system using image recognition according to the present invention, a low-cost fixed camera and a low-cost vehicle detection camera are installed in the outflow lamp, a violation camera is checked through the fixed camera, and the vehicle detection is performed. After photographing the license plate of the violating vehicle through the camera, the owner can issue a penalty notice, thereby reducing the initial installation cost and reducing errors in tracking the violating vehicle.

In addition, by preventing the entry of the vehicle into the spill ramp, it prevents vehicle delay caused by the vehicle to induce smooth traffic flow, and prevents the waste of manpower by controlling the violating vehicle through the camera. Ensuring the driver's consciousness by establishing a traffic order by cracking down on traffic offenses and cracking down on traffic order violations.
