And a center device for determining a vehicle corresponding to the vehicle number set as the control target vehicle number for a second reference time or more as an illegal parking vehicle among the control target vehicle numbers, wherein the center apparatus includes a license plate from an image received from the photographing apparatus. The license plate area is extracted based on the color and shape of the license plate, and the vehicle number is discriminated from the extracted license plate area.For each extracted license plate area, the extraction point of the license plate area, the vehicle number recognized in the license plate area, and the circle from which the license plate area is extracted Includes image storage location, extracted license plate area coordinates, and sub-monitoring area identification information. The license plate recognition unit generating a license plate area identification information; Based on the license plate recognition information generated by the license plate recognition unit, if the same vehicle number is recognized for the first reference time or more, the vehicle is regarded as a parked vehicle, and the license plate recognition information is recorded in the parking vehicle database. When the second reference time elapses from the point of discovery of the vehicle in progress, the license plate area recognition information in which the vehicle number recognized from the image photographing the lower surveillance region corresponding to the position where the vehicle is stopped is recorded in the parking vehicle database. If it matches the vehicle number included in, the vehicle is judged to be an illegal parking vehicle, and the control point, vehicle number, storage location of the recorded image at the start of illegal parking control, storage location of the recorded image at the elapsed time of illegal parking control reference time, Coordinate of extracted license plate area and sub-monitoring area identification information It is carried out contact-breaker unit for generating a crack down the vehicle information; A photographing apparatus controller for controlling a photographing apparatus installed at a point where the parked vehicle is located by a horizontal angle, a vertical angle, and a zoom ratio that allow the photographing of the license plate area of the parked vehicle at the time when the second reference time elapses; A storage unit for storing photographing device control information including a horizontal angle, a vertical angle, and a zoom ratio set for the photographing apparatus, the license plate area recognition information, the parking vehicle database, and the intermittent vehicle information; And a network connection unit connected to a wired / wireless communication network to provide a means for transmitting and receiving data with the camera.

This enables illegal parking control over a wide area with a small number of personnel, and reduces the time to crack down by performing license plate recognition and fine billing of the vehicle from the images actively captured by the center unit.

Referring to FIG. 3, the GUI is composed of an image area, a camera control button, camera information, surveillance area information, network information, license plate information, a list of control target vehicles, a system control button, and the like. In the image area, an image photographed by a camera selected from cameras 110-1 to 110-n connected to the center apparatus 130 is output. The camera control button is for manual control of the camera such as pan / tilt / zoom. The camera information includes identification information of the lower surveillance area that the camera is shooting and motion information of the camera including the vertical angle, horizontal angle, and zoom level of the camera. Surveillance area information includes graphic information on the sub-sensitized area where the image output to the image area is photographed among the sub-sensitive areas that each camera is in charge of, and the network information includes information on the network connection state and frame rate. The license plate information includes a license plate recognition result image and a recognized vehicle number. The list of vehicles subject to crackdown is a list of vehicles that are found to be stopped and that have not reached the crackdown reference time. The system control button includes a button for instructing operation and termination of the system, a button for instructing setting of a lower area, and a manual control button.

The surveillance region setting unit 220 sets the surveillance region of each of the cameras 110-1 to 110-n that are connected. The surveillance area is composed of a plurality of subordinate surveillance areas. In FIG. 4, a lower surveillance region constituting a surveillance region that a specific camera is responsible for is shown. Referring to FIG. 4, the surveillance area 400 includes a total of twelve sub-surveillance areas 410 to 465, each of which is set at a distance of 50m forward and backward based on the point where the camera 110-1 is installed in the lane adjacent to the sidewalk. It is composed of Alternatively, the surveillance area may be configured as a wide area monitoring area of the front lower monitoring area, the lower lower monitoring area, and the rear lower monitoring area based on the point where the camera is installed. As such, when the surveillance area is divided into a wide area monitoring area, an area except the roadway is an unprocessed area so that the image processing performed by the vehicle recognition unit 230 and the license plate recognition unit 240 is performed only for the driveway area. Is set.

The operator located in the center is a camera (for example, a camera having reference number 110-1, which is intended to set a surveillance area through the user interface unit 210, hereinafter referred to as "first camera" corresponding to the last digit of the reference number). ), The camera information is sequentially set from the first sub-monitoring area 410 to the twelfth sub-monitoring area 465 using the camera control button 214. To this end, the operator observes the monitor 212 and adjusts the angle of the camera using the tilt / pan button to control the photographing of the first sub-monitoring area 410 by the first camera 110-1. When the angle adjustment for the first camera 110-1 is completed, the operator may use the zoom button so that the vehicle and the license plate of the vehicle positioned in the first sub-monitoring area 410 can be photographed. To control. The camera setting process is repeatedly performed until the setting for the n-th camera 110-n is completed.

When the operator presses the setting complete button, the surveillance area setting unit 220 generates camera control information set for the first camera 110-1 to the nth camera 110-n to correspond to the cameras 110-1 to 110. -n). The camera control information includes the monitoring time of each sub-monitoring area and the horizontal angle, vertical angle, and zoom ratio of the camera set for each sub-monitoring area. On the other hand, the monitoring time for each sub-monitoring area may be set to a value calculated by dividing the illegal parking control standards 5 minutes by the number of sub-monitoring area. For example, when there are 12 lower monitoring zones, the monitoring time for each of the lower monitoring zones is set to about 25 seconds (or 20 seconds except 5 seconds for a reference time for determining whether a vehicle is parked). In this way, it is possible to control the respective sub-monitoring areas by sequential shooting of the sub-monitoring areas without a separate operation for the camera set to photograph each sub-monitoring area. In this case, the monitoring time for each of the sub-monitoring areas may be set differently for each area. Each of the cameras 110-1 to 110-n stores camera control information received from the center apparatus 130 through the network connection unit 280 in a storage unit provided therein. When each camera 110-1 to 110-n receives an operation command from the center device 130, the cameras 110-1 to 110-n sequentially photograph the lower monitoring area by the stored camera control information and transmit the same to the center device 130.

The vehicle recognition unit 230 extracts a vehicle area through image processing of an image received in real time from each of the cameras 110-1 to 110-n installed at an intermittent place through the network connection unit 280. That is, the vehicle recognition unit 230 estimates the vehicle area in the received image based on the symmetry of the headlights, the presence of shadows, the presence or absence of a window shape, and the like. The extracted vehicle area is represented by the upper left and lower right coordinates (or the upper right and lower left coordinates) of the area recognized as the vehicle in the received image. At this time, the coordinates representing the vehicle area are calculated based on the resolution of the received image or calculated by matching the received image on a predetermined coordinate. The vehicle recognition unit 230 generates vehicle region recognition information including an extraction time point of the vehicle region, coordinates of the extracted vehicle region, and lower surveillance region identification information for each lower monitoring region, and stores the vehicle region recognition information in the storage unit 270. .

The license plate recognition unit 240 extracts the license plate area from the extracted vehicle area or the received image and determines the vehicle number from the extracted license plate area. At this time, the license plate recognition unit 240 identifies the license plate area in the vehicle area based on the color and shape of the license plate. To this end, the center device 130 stores yellow, green, white and the shape of the license plate, which is the color of the license plate. The vehicle region or the license plate region extracted from the received image is inclined according to the direction of the vehicle. Since this acts as a factor to lower the recognition rate of the vehicle number, correction is necessary. Since the correction for the tilt of the image uses a known technique, a detailed description thereof will be omitted. The license plate recognition unit 240 recognizes the vehicle number by extracting the feature of the character from the image of which the tilt is corrected through pre-processing such as image binarization and blob labeling based on the basic features of the license plate. When the vehicle number recognition by the license plate recognition unit 240 is completed, the camera returns to the original position and photographs the lower surveillance area. On the other hand, when the license plate area is recognized in the vehicle area, the size ratio of the license plate area to the vehicle area may be used as data for determining the license plate area. In addition, the license plate recognition unit 240 is the extraction point of the license plate area for each extracted license plate area, the vehicle number recognized in the license plate area, the storage location of the original image extracted the license plate area, the coordinates of the extracted license plate area, and lower The license plate area recognition information including the surveillance area identification information is generated and stored in the storage unit 270.

Recognition of the vehicle area and the license plate area of the vehicle recognition unit 230 and the license plate recognition unit 240 as described above is a specific area from the image known to those of ordinary skill in the art prior to the application of the present invention It can be achieved by a known image processing technique for extracting. However, in the present invention, the recognition conditions of the known image processing technology are changed and applied to the recognition of the vehicle area or the license plate area. In addition, a known character recognition technique is used as a technique for identifying the vehicle number from the vehicle area by the license plate recognition unit 240.

The camera controller 250 controls the operations of the cameras 110-1 to 110-n that are connected. The operator located in the center may adjust the pan / tilt / zoom of each of the cameras 110-1 to 110-n by using the user interface unit 210, and the camera controller 250 may control the control command received from the operator. Camera control information including a horizontal angle, a vertical angle, a zoom level, and a monitoring time of a corresponding camera is generated and transmitted to the control target camera through the network connection unit 280. The camera to be controlled operates based on camera control information received from the center apparatus 130. When the camera control information is setting information for a surveillance area, the camera to be controlled stores the received camera control information in a storage unit provided therein. Such generation of camera control information by the camera controller 250 may be caused by the enforcement unit 260.

The enforcement unit 260 handles the enforcement service for the illegal parking vehicle. The enforcement service by the enforcement unit 260 may be set differently according to the divided state of the monitoring area.

When the surveillance area is composed of a number of sub-monitoring areas (for example, less than nine) which are not easy to extract the license plate area from the image photographed by the camera, the enforcement unit 260 operates as follows. That is, the enforcement unit 260, if the vehicle area is recognized at the same position for a predetermined time (for example, 5 seconds) or more based on the vehicle area recognition information generated by the vehicle recognition unit 230, then the vehicle area is identified. The existing vehicle is regarded as a parking vehicle, and the corresponding vehicle area recognition information is recorded in the parking vehicle database. When the vehicle is found to be stopped, the enforcement unit 260 instructs the license plate recognition unit 240 to extract the license plate area from the vehicle area, and stores the license plate area recognition information generated by the license plate recognition unit 240 in the license plate database. Record it.

The enforcement unit 260 responds when the illegal parking control reference time (for example, 5 minutes) has elapsed from the discovery time of the vehicle being parked (that is, when the license plate area recognition information of the vehicle is recorded in the license plate database). Controls the camera to shoot the corresponding lower surveillance area. Such camera control may be configured to be performed by the camera controller 250 by driving the enforcement unit 260. When photographing of the lower surveillance area is performed, the vehicle recognition unit 230 extracts the vehicle area from the image received from the camera. The enforcement unit 260 determines that the vehicle is an illegal parking vehicle if the extracted vehicle region matches the vehicle region included in the vehicle region recognition information recorded in the parking vehicle database.

Next, the enforcement unit 260 extracts the license plate area from the vehicle area extracted by the license plate recognition unit 240, grasps the vehicle number of the corresponding vehicle, and confirms whether it is the same as the vehicle number of the vehicle stored in the license plate database unit. Control to check whether or not. In this case, camera control information corresponding to the coordinates of the vehicle area and the license plate area extracted by the vehicle recognition unit 230 and the license plate recognition unit 240 may be used for controlling the camera. If it is confirmed that the same vehicle, the enforcement unit 260 may control the control point, the vehicle number, the storage location of the recorded image at the start of illegal parking control, the storage location of the captured image at the elapsed time of the illegal parking control, and the license plate extracted. The intermittent vehicle information including the coordinates of the region and the sub-monitoring region identification information is generated and recorded in the intermittent vehicle database.

On the contrary, as described with reference to FIG. 3, when the monitoring area includes 12 lower monitoring areas, the enforcement unit 260 operates as follows. That is, the enforcement unit 260 is a vehicle that is parked when the same vehicle number is recognized for a predetermined time (for example, 5 seconds) or more based on the license plate area recognition information generated by the license plate recognition unit 240. The license plate area identification information is recorded in the parking vehicle database. If a vehicle is found to be stopped, the enforcement enforcement unit 260 may detect the illegal parking control reference time (for example, 5 minutes) from the time of discovery of the vehicle being parked (that is, when the license plate area recognition information of the vehicle is recorded in the license plate database). When elapsed), the corresponding camera controls to capture the corresponding lower surveillance area. Such camera control may be configured to be performed by the camera controller 250 by driving the enforcement unit 260. When the photographing of the lower surveillance area is performed, the license plate recognition unit 240 extracts the license plate area from the image received from the camera. The enforcement unit 260 determines that the vehicle is an illegal parking vehicle if the vehicle number recognized from the extracted license plate area matches the vehicle number included in the license plate area recognition information recorded in the parking vehicle database. Finally, the enforcement unit 260 may control the crackdown time, the vehicle number, the storage location of the captured image at the start of illegal parking control, the storage location of the captured image at the elapsed time of the illegal parking control reference time, the coordinates of the extracted license plate area, and Interrupted vehicle information including lower surveillance area identification information is generated and recorded in the intermittent vehicle database.

In addition, the enforcement unit 260 outputs a guide broadcast notifying the movement of the vehicle to a speaker installed in the corresponding area when the parking vehicle is found. The announcement is pre-recorded and stored, and broadcasts different contents such as vehicle movement warnings and enforcement warnings depending on the stop time. Further, the enforcement unit 260 creates a charging document for the vehicle identified as illegal parking based on the vehicle information. At this time, the billing document describes the vehicle number, the time of the car's crackdown (starting and ending time of parking), the image of the crackdown (starting time of parking and exceeding illegal parking control standards), and location. On the other hand, the vehicle area recognition information and license plate area recognition information may be configured to be recorded in the corresponding database by the vehicle recognition unit 230 and license plate recognition unit 240, respectively.

The storage unit 270 includes camera control information, vehicle area recognition information, license plate area recognition information, and parking vehicle database for capturing a lower surveillance area constituting a surveillance area corresponding to each of the cameras 110-1 to 110-n. The vehicle number database, the intermittent vehicle database, and the announcement broadcast are stored. In addition, the storage unit 270 temporarily stores images taken by the cameras 110-1 to 110-n, vehicle areas and license plate areas extracted by the vehicle recognition unit 230 and the license plate recognition unit 240, and the like. You can set the storage area.

The network connection unit 280 is connected to a wired or wireless communication network to provide a means for transmitting and receiving data with each of the cameras 110-1 to 110-n. The center device 130 transmits the camera control information and the audio signal for the enforcement to the respective cameras 110-1 through 110-n through the network connection unit 280, and each camera 110-1 through 110-n. Receive the image taken from. Examples of network protocols supported by the network connection unit 280 include TCP / IP, HTTP, ARP, PARP, ICMP, DHCP, FTP, SMTP, and the like, and communication lines include xDSL, Ethernet, and LAN. The cameras 110-1 to 110-n and the center device 130 may perform communication by various communication methods. For example, the xDSL modem may include the cameras 110-1 to 110-n and the center device 130. It can be employed as a communication means between.

Camera information is sequentially set up to the surveillance region 465. When the operator presses the setting complete button, the surveillance area setting unit 220 generates camera control information set for the first camera 110-1 to the nth camera 110-n to correspond to the cameras 110-1 to 110. -n), and each camera 110-1 to 110-n stores the camera control information received from the center apparatus 130 through the network connection unit 280 in a storage unit provided therein. When each camera 110-1 to 110-n receives an operation command from the center device 130, the cameras 110-1 to 110-n sequentially photograph the lower monitoring area based on the stored camera control information and transmit the same to the center device 130 (S500). ).

The center apparatus 130 selectively controls the operation of the vehicle recognition unit 230 according to the degree of division of the surveillance region that each camera 110-1 to 110-n is in charge of. If the monitoring area is configured as a wide area monitoring area (S510), the vehicle recognition unit 230 is received in real time from each camera (110-1 to 110-n) installed in the intermittent place through the network connection unit 280 The vehicle region is extracted through image processing on the image (S520). The vehicle recognition unit 230 generates vehicle region recognition information including an extraction time point of the vehicle region, coordinates of the extracted vehicle region, and lower surveillance region identification information for each lower monitoring region, and stores the vehicle region recognition information in the storage unit 270. (S530). The enforcement unit 260 searches the stored vehicle area recognition information, and if it is determined that there are vehicle areas (that is, vehicle areas having the same coordinates) that exist at the same position for more than 5 seconds, the license plate recognition unit 240 ), The license plate recognition unit 240 extracts the license plate area from the extracted vehicle area to determine the vehicle number (S540). In addition, the license plate recognition unit 240 is the extraction point of the license plate area for each extracted license plate area, the vehicle number recognized in the license plate area, the storage location of the original image extracted the license plate area, the coordinates of the extracted license plate area, and lower The license plate area recognition information including the surveillance area identification information is generated and stored in the storage unit 270 (S550). Next, the enforcement unit 260 retrieves the stored license plate area recognition information to grasp the vehicle existing at the same location for a predetermined time, and notifies movement after 3 minutes from the time when the vehicle is recognized as a parking vehicle according to the setting. The system outputs the system broadcast, and after 5 minutes, performs a crackdown service such as determining that the vehicle is illegal parking (S560).
