And areas.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 1 to 9.

1 is a view for explaining an illegal parking control system according to an embodiment of the present invention.

Referring to FIG. 1, an illegal parking control system according to an embodiment of the present invention is connected to a field system that monitors a parking stop violation of a vehicle by controlling a camera and a communication network connected to the field system, so that the overall information on the information of the parking stop violation vehicle may be obtained. It consists of a center system that handles management, issuance of notices, notifications to enforcement personnel or towing establishments, past facts inquiry, and other complaint response tasks.

The camera is a CCTV camera, which may be in the form of a digital camera, a box camera, a speed dome camera, or the like, and is located near a center on a four-way road using a predetermined support mechanism based on a sidewalk as shown in FIG. 1. It is preferably installed in. However, the present invention is not limited thereto, and the camera may be installed at a suitable position on a road such as 3 or 5 street, on a center line of a general reciprocating road, or on a one-way street.

In the present invention, as well as using a wide pan (pan: azimuth) and a tilt (tilt), for example, pan 0 ~ 350 degrees, tilt -70 ~ 20 degrees (± 5 degrees error) applied to the camera, High speed rotation, e.g. pan: 0.1-50 degrees per second (± 0.2 degrees error), and tilt: 0.1-10 degrees per second (± 0.2 degrees error), stopping the vehicle for all directions on the road. Can be monitored. As described above by way of example of the camera used in the present invention, but is not limited to this, any other CCTV camera that operates at more than pan / tilt and rotation speed may be used.

For example, in the field system, the plurality of detection areas 1, 2, 3,... 16 are repeatedly monitored sequentially using the camera. At this time, when the field system detects the entry vehicle in each detection area from the image photographed by the camera, the vehicle number is recognized from the image including the vehicle license plate obtained by controlling the camera. At this time, the field system transmits the parking violation fact information including the recognized vehicle number, the image including the vehicle, the violation place, the vehicle size, the vehicle color and the violation time to the center system.

When the center system receives the parking violation fact information, the center system may issue a parking violation notice through a vehicle inquiry based on the parking violation fact information.

Here, the detection areas (1, 2, 3, ..., 16) that the camera of the field system monitors are prohibited from stopping at the last lane in each vehicle driving direction, that is, 4 roads and 8 driving directions as shown in FIG. Exist in zones. Stopped areas are specified in the Road Traffic Act, such as intersections, crosswalks, and crossings. As shown in FIG. 1, each parking stop zone is divided into two or more areas (3, 4, 5, ... possible) according to the photographing distance of the camera, and a detection area is set. For example, the parking stop area in the left travel direction of the left road of FIG. 1 is divided into predetermined intervals, for example, 50 m intervals, and is set as the detection areas of 1,2. Further, the parking stop area in the right traveling direction of the left road of FIG. 1 is divided and set as the detection areas 3 and 4. Similarly, in each driving direction of the remaining roads, each parking stop zone is divided into two detection zones, so that (5,6), (7,8), (9,10), (11,12), (13, 14), (15, 16) and the like. As described below, the detection areas can be set in a similar manner to the above for a plurality of directions even at three distances, a general reciprocating road, and the like. The dividing and setting of each parking stop zone into a plurality of detection areas is intended to enable smooth and effective vehicle detection from an image captured by the camera, and the camera's shooting distance, that is, appropriately focused. It can be set according to the distance at which a clear image can be obtained.

Accordingly, in the present invention, detection areas that are expected to enter and exit the vehicle by using high-speed pan / tilt features such as a speed dome camera regardless of road conditions in one-way streets, round-trip lanes, three- and four-way stop areas, etc. Periodic monitoring at speed and automatic detection of vehicles that violate the parking rules of the Road Traffic Act will enable efficient management and notification of violations. In this case, the present invention uses a single camera rather than using three or more cameras, thereby reducing costs and making it easier to maintain, and eventually preventing and controlling illegal parking vehicles more efficiently.

Hereinafter, the illegal parking control system according to an embodiment of the present invention will be described in more detail.

2 is a block diagram of an illegal parking control system 200 according to an embodiment of the present invention. Referring to FIG. 2, the illegal parking control system 200 includes an on-site system 210 and a center system 220. The field system 210 includes a control unit 211, a camera 212, a detection and number recognition unit 213, a video server 214, an amplifier 215, a speaker 216, a microphone 217, and In addition to the communication unit 218, in addition to the multi-function power supply for supplying appropriate power to each unit may be further included. The center system 220 includes a hub 221, a database (DB) server 222, a video storage server 223, a data processing server 224, a notice issuing server 225, and an operation terminal 226. It includes. Hereinafter, a flowchart of FIG. 3 will be referred to for describing an operation of the parking stop system 200.

First, the camera 212 is installed at an appropriate position on a rotary center such as 3, 4, 5 distance, on a center line of a general reciprocating road, or on a one-way street. As described in the description of FIG. 1, each parking stop zone is divided into two or more areas (3, 4, 5, ..., possible) according to the shooting distance of the camera 212 for each vehicle driving direction. And detection areas are set. In order to sequentially monitor the set detection areas as described above, the installation operator may input a predetermined setting value to the control unit 211 to allow the control unit 211 to recognize the detection areas (S310). In this case, the general standard road may be set in advance in the controller 211 to recognize the detection areas. Accordingly, the controller 211 controls the camera 212 to repeatedly photograph the sequence areas of the detection areas set as described above.

For example, the controller 211 may control to sequentially photograph the detection areas of FIG. 1 in the order of 1,2,3, ..., 16,1,2,3 ... With respect to the detection areas 1 to 14 in which each parking stop zone is divided as shown in FIG. 4 in the three-way roundabout, the control unit 211 controls 1,2,3, ..., 14,1,2. You can control to shoot sequentially by repeating the sequence of .3. In addition, the control unit 211 controls 1,2,3, ..., 8 for the detection areas 1 to 8 in which each parking stop zone is divided as shown in FIG. It is possible to control to photograph sequentially by repeating the order of 1, 2, 3, .... Here, the position of the detection region at which imaging starts, for example, number 1 may be set to any other position.

As described above, when the camera 212 starts capturing under the control of the controller 211, the detection and number recognition unit 213 analyzes the movement of the captured image, for example, an image as shown in FIG. S320). At this time, the detection and number recognition unit 213 may detect whether there is a vehicle entering each detection area according to a predetermined image processing algorithm (S330).

For example, in order to detect a vehicle from an input image, first, a night pass image may be pre-processed such as low pass filtering, Gaussian filtering, and median filtering. For the weekly image, the input image may be processed according to a histogram algorithm, an edge algorithm, a labeling algorithm, and the like without preprocessing. The histogram algorithm analyzes an image by allocating the smallest bit value that occurs frequently and assigning a larger bit value as the frequency size decreases. The edge algorithm is a method of recognizing an edge where a color or density rapidly changes in an image. The labeling algorithm finally extracts the area that is expected to be a vehicle based on the analysis result. The detection and number recognition unit 213 may perform the above algorithms based on the color value of the vehicle entering the forbidden stop area by distinguishing the road, the sidewalk, etc. from the image as shown in FIG. The number of vehicles, vehicle size, vehicle color, vehicle coordinates, etc. can be detected.

When the vehicle entering the detection area is detected according to the operation of the detection and number recognition unit 213 as described above, the controller 211 controls the zoom in operation of the camera 212 based on the vehicle coordinate value. Accordingly, the control is performed such that a photograph including the license plate, for example, a still image is obtained (S340 and S350).

At this time, the detection and number recognition unit 213 recognizes the vehicle number from the image including the license plate of the detected vehicle according to a predetermined image processing algorithm (S360). For example, pre-processing such as low pass filtering, Gaussian filtering, and median filtering may be performed to recognize the vehicle number from the input image including the license plate. Next, in order to reduce the amount of computation by narrowing the area to handle the separation and recognition of the letters related to the license plate, the license plate candidates are divided into upper, middle, and lower positions in a predetermined manner according to the old, new, latest, and transportation business, The recognition is attempted at an appropriate priority according to the position of the coordinate value of the candidate area. When the candidate regions are ranked in this manner, the candidate images are normalized to a certain size to facilitate the next step processing. The normalized image can be corrected through slant shift with respect to horizontal and vertical tilt, and character separation and recognition are attempted in different ways according to the type of license plate. For example, the license plate type is' Daejeon 1 gun 9098 'for the old type and '58 beam 5486' for the new type. In the case of a local name. In this way, the number of characters according to the license plate type, character size, character type, etc. are estimated, and using a neural network and a pattern recognition technology, a 4-digit serial number (1370 in Fig. 7), a 2-digit model code (03 in Fig. 7), 1 Characters corresponding to the place usage code (see FIG. 7) are recognized, and if there is a character corresponding to the region name, the region name character is also recognized.

When the detection and number recognition unit 213 recognizes the vehicle number in the above manner, the control unit 211 generates parking stop violation information including the vehicle number. The parking violation fact information may include, in addition to the vehicle number, an image including the vehicle, a violation place, a vehicle size, a vehicle color, and a violation time. In this case, the violation place is a region where the camera 212 is installed, and a corresponding code may be managed by the controller 211. In addition, the violation time may be input through a predetermined timer connected to the controller 211 as a time when the current vehicle is photographed or the vehicle number is recognized.

Although the detection and number recognition unit 213 attempts to recognize the vehicle number in the same manner as above, when there is a lot of noise in the image due to weather, time zones, or other environmental effects, the vehicle number may not be recognized. At this time, in order to be able to manually follow-up measures such as vehicle number recognition and parking violation notification, the control unit 211 generates parking violation fact information including information except the vehicle number. For example, if the vehicle number is not recognized, the controller 211 may generate an image including the vehicle, a violation place, a vehicle size, a vehicle color, a violation time, and the like as parking violation fact information.

The parking violation fact information is transmitted to the center system 220 through the communication unit 218. The communication unit 218 is a communication network connecting the field system 210 and the center system 220, for example, for data transmission to other networks such as a local area network (LAN), the Internet, a wireless network, and the like. The parking violation fact information is processed and transmitted to the center system 220 in accordance with the protocol (S360). In addition, the image photographed by the camera 212 may be distributed by a predetermined distributor and input to the video server 214, where the video server 214 compresses the image captured by the camera 212 in real time, such as an image The processing may be performed, and the processed video data may also be transmitted to the center system 220 through the communication unit 218. Image processing of the video server 214 and causing the video server 214 to transmit the processed video data to the center system 220 may be controlled by the operation terminal 226 of the center system 220. In addition, it is also possible to make such control by the control part 211 as needed.

In addition, the on-site system 210 may be used to amplify the output signal of the microphone 217 and the microphone 217 for inputting a voice in order to enable the crackdown agent to directly explain the vehicle in violation of the parking lot. An amplifier 215 and a speaker 216 for transmitting the output signal of the amplifier 215 may be provided.

After generating the parking violation fact information from the vehicle number recognition as described above, in order to repeat the above process (S310 ~ S360) in the next detection area, the control unit 211 is set in advance by controlling the pan / tilt of the camera 212 The image of the detection area may be taken (S370).

On the other hand, when the center system 220 receives the violation vehicle-related data such as parking violation fact information, video, etc. from the field system 210 through the hub 221, the center system 220 is the parking violation fact as follows: Based on the information, you can automatically issue a parking violation notice through a vehicle inquiry. Violation vehicle-related data such as parking violation fact information and video received from the field system 210 may be transmitted to a center system operating in another region through the hub 221 to allow data sharing.

The DB server 222 of the center system 220 stores and manages the received parking violation fact information. The video data captured by the camera 212 in real time is stored and managed in the video storage server 223.

According to the result of the vehicle number recognition attempt in step S360 of FIG. 3, when the recognized vehicle number exists (S380), the vehicle number included in the received parking violation fact information as shown in FIG. 8, and the vehicle is included. The image, the violation place, the vehicle size, the vehicle color, the violation time, and the like are managed in the enforcement target list of the DB server 222 (S390). In this case, the image including the vehicle may include a far image, a near image, and an enlarged image of a license plate as shown in FIG. 8.

In particular, the DB server 222 temporarily stores the parking violation fact information received from the field system 210, and finally, when the parking violation fact information including the same vehicle number is received again in the corresponding detection area, the target subject to crackdown is finally received. You can manage it in a list. For example, when the camera 212 sequentially photographs the detection areas as shown in FIG. 1, and the detection and number recognition unit 213 recognizes the corresponding vehicle number again in the next period, for one detection area, The DB server 222 may finally manage the parking violation fact information for the vehicle in the crackdown target list. This is because the parking time is restricted to 5 minutes or less in the area where parking stop is prohibited under the road traffic law. That is, the controller 211 preferably controls the camera 212 to repeatedly photograph the corresponding detection area at a cycle of, for example, five minutes or more, which is specified in the road traffic law.

The data processing server 224 accesses the vehicle inquiry server of the administrative network and inquires the vehicle according to the parking stop fact information managed by the DB server 222. The data processing server 224 may be linked to a vehicle inquiry server linked to an administrative network operated by the government, and the vehicle inquiry server requests a vehicle corresponding to the vehicle number to correspond to an address, a borrower, a registration number, a past violation fact, and the like. Vehicle information can be received. In addition, the data processing server 224 may transmit the parking violation facts information to the towing office operating terminal 226, so that the tow office can go to the violation place to take the towing action for the vehicle. It is possible.

Accordingly, the notification issuing server 225 issues a parking violation notification letter for the vehicle in accordance with the inquiry track (S410). As shown in Figure 9, the notice of parking violations, the address of the sender, the address of the recipient (the borrower), the name of the borrower, the violation time, the opinion statement period, vehicle number, location of violation, penalty, related laws and the like.

 In FIG. 2, the operation terminal 226 is a terminal for managing and inquiring all information of the center system 220, and among the DB server 222, the video storage server 223, and the data processing server 224. One or more of these may be approached to query a vehicle for violations of the vehicle, or to respond to a complaint and provide information about the violation. For example, the operation terminal 226 may access the DB server 222 and query the parking violation fact information by the vehicle number. In addition, the operation terminal 226 may access the video storage server 223 and inquire the video photographed at the parking stop violation location of the vehicle by the vehicle number. In addition, the operation terminal 226 can access the next step by accessing the administrative network through the data processing server 224. In addition, the operation terminal 226 transmits the parking violation fact information to the portable terminal of the parking enforcement agent, so that the information can be quickly shared with the parking enforcement personnel being monitored at the parking violation location of the vehicle, so that the driver can control and control the driving. In addition, vehicle traffic control can be performed, and thus traffic violations can be effectively prevented, controlled or smoothly flowed. In addition, as described above, the operation terminal 226 may control to transmit the moving image data processed by the video server 214 of the field system 210 to the center system 220, wherein the camera 212 The video data captured in real time may be stored and managed in the video storage server 223.

On the other hand, if the vehicle number is not recognized in step S380, except for the vehicle number, the image containing the vehicle included in the received parking violation fact information, violation place, vehicle size, vehicle color and violation time, etc. In the DB server 222, the license plate is managed in an unrecognized list that is not recognized (S420). In this case, instead of automatically checking the vehicle or issuing a parking violation notice, the center system operator recognizes the vehicle number on the license plate with the naked eye from an image including the vehicle so that the parking violation notification can be issued (S430). ).

As described above, in the illegal parking control system 200 according to the present invention, only one camera 212 such as a speed dome camera is operated to effectively monitor the parking violations at low cost. In the present invention, parking stop areas in each travel direction, such as three distances and four distances, are set as detection areas divided into a plurality of areas according to the photographing distance of the camera 212. Accordingly, the control unit 211 of the field system 210 controls the camera 212 to repeatedly photograph the plurality of detection areas periodically, and the detection and number recognition unit 213 controls the camera 212 to be photographed. It detects whether there is a vehicle entering each detection area from the captured image, and recognizes the vehicle number from the image including the vehicle license plate for the detected vehicle. Accordingly, the controller 211 controls the zoom-in operation of the camera 212 so that an image including the vehicle license plate is obtained when there is a vehicle detected in each detection area, and the vehicle number and the vehicle are included. Information including at least one or more of an image, a violation place, a vehicle size, a vehicle color, and a violation time may be generated as parking violation fact information.

The parking violation fact information is transmitted to the center system 220, the DB server 222 of the center system 220 is to store and manage the parking violation fact information based on the recognized vehicle number. The data processing server 224 of the center system 220 accesses the vehicle inquiry server of the administrative network based on the parking violation fact information, and inquires the vehicle, and the notice issuing server 225 transmits the vehicle to the vehicle in accordance with the inquiry. You will be able to issue a Notice of Parking Violation.

The illegal parking control system and method according to the present invention can be modified and applied in various forms within the scope of the technical idea of the present invention. For example, it is preferable that the field system and the center system of the above embodiment are operated at the center and the center far away from the site, but if necessary, the field system and the center system are integrated and operated as one in the field, or only the camera is installed in the field. Other field and center systems can also be integrated into the center. After all, the embodiments and drawings are merely for the purpose of describing the details of the invention, and are not intended to limit the scope of the technical idea of the invention, the scope of the present invention is not limited to the claims to be described later and It should be judged to include an even range.

As described above, in the illegal parking control system and method according to the present invention, the detection areas expected to enter and exit the vehicle at a high speed periodically using the high speed pan / tilt characteristics of one camera regardless of the road conditions in the parking prohibited area. By monitoring and automatically detecting vehicles that have violated the parking rules under the Road Traffic Act, it is possible to manage and notify the violations, thus reducing costs for the crackdown of illegal parking vehicles, making maintenance easier, and There is an effect that can effectively provide the prevention and enforcement services of parking vehicle violations.
