The present invention relates to a parking management system using vehicle number recognition, and more particularly, improves the number recognition rate of a vehicle even when the number of the vehicle is not properly recognized by obstacles such as weather irregularities or obstacles. The present invention relates to a parking management system using vehicle number recognition, which can reduce the recognition time for the vehicle number.

In general, a specific place where a parking facility is installed, such as a department store, an apartment, and a paid parking lot, uses a large number of manpower for managing a vehicle. However, in order to reduce labor costs due to the use of manpower, a system is installed at the entrance and exit side of the parking lot, photographing the license plate of the entering vehicle, recognizing it with letters and numbers, and identifying the vehicle and calculating the parking fee. Is being developed.

1 is a perspective view schematically showing the configuration of a parking management system using a conventional vehicle number recognition.

As shown in FIG. 1, an image is generated from the image photographing unit 4 and an image photographing unit 4 for photographing a license plate of a vehicle passing through a predetermined point where the vehicle detecting unit 2 is installed and processed. And a number extraction unit 6 for extracting data corresponding to the license plate.

However, in the conventional parking management system using the vehicle number recognition as described above, a CCD camera or an LPR camera is mainly used as the image photographing unit 4 for photographing the license plate of the vehicle. Since the CCD camera, that is, the analog camera, recognizes the license plate of the vehicle as one frame picture, the recognition rate of the license plate of the vehicle is lowered due to obstacles such as weather irregularities or obstacles.

In addition, the LPR camera, that is, the digital camera has a higher recognition rate of a vehicle license plate than an analog camera for environmental changes or obstacles, but there is a problem that the installation cost of the parking management system is generally increased because it is relatively expensive equipment.

In addition, as a vehicle detecting unit 2 for detecting a vehicle entering the entrance and exit of the parking lot, a loop or a corresponding sensing means is further installed at a corresponding position, which makes the installation work inconvenient and increases the installation cost. have.

In addition, when photographing the vehicle number of the image capturing unit 4 according to the operation of the vehicle detecting unit 2, the image capturing unit 4 which is a digital camera at the moment of detecting the vehicle by the vehicle detecting unit 2 captures only one picture. Due to weather shooting, for example, rainfall, snowfall, fog, and the presence of sunny and shaded areas in the license plate area (shooting area), or obstacles, for example, lines waiting for issuance of a parking ticket from a parking ticket machine (not shown) Due to limited shooting conditions such as a case in which the license plate of the reverse vehicle is blocked by the bumper of the advanced vehicle when the reverse vehicle enters the installation area of the vehicle detecting unit 2 very close to the rear of the vehicle. Since the license plate of the vehicle is not clearly photographed, there is a problem that the recognition rate is significantly lowered.

In addition, the vehicle entering by turning left or right in front of the recognition position has a problem that the recognition rate is lowered because the side of the license plate is photographed if the rotation angle is not fixed even if a loop for recognition is installed because the entry angle is very diverse.

In addition, among the pictures taken by the photographing means, there is a problem that the number is difficult to read by the reflected light or the shadow of the bonnet of the vehicle in the open air.

In addition, the data corresponding to the vehicle number generated from the number extraction unit 6 is, for example, text data including simply letters and numbers such as' Seoul 1 is 1234 'and '80 is 1234'. And the color manager for the distinction between the commercial vehicle number and the commercial vehicle number, the administrator of the vehicle finds and recognizes the text data corresponding to the vehicle number from the tens or hundreds of text data displayed on the monitor (for example, once In order to save the parking fee, the driver of the occupied vehicle is a check operation for preventing the parking ticket from being issued again in an unfair manner before leaving the vehicle.

In addition, there is a problem of time constraints for recognizing numbers one by one when recognizing numbers by conventional simple multiplexing.

In addition, despite the variety of license plates currently in operation, there is a problem that excessive consumption of recognition time is generated by uniformly photographing the photographing number.

Therefore, a parking management system and a method using a new vehicle number recognition are emerging to simplify the installation of the parking management system, reduce its cost, and allow the administrator to manage the parking of the vehicle more easily and conveniently.

Therefore, an object of the present invention is to provide a parking management system using a vehicle number recognition that can save the installation cost by photographing the license plate of the vehicle with an analog camera such as a CCTV camera.

In addition, another object of the present invention is to limit the shooting conditions that occur during the continuous shooting of the vehicle entering the entrance and exit of the parking lot in real time and depending on the operation of the vehicle sensing member (such as irregular weather or obstacles or irregular entry direction, etc.) By overcoming the above), a parking management system using the vehicle number recognition that can improve the recognition rate of the vehicle number is provided.

In addition, another object of the present invention is to provide a parking management system using a vehicle number recognition that can simplify the overall installation work of the parking management system and save the installation cost by not installing the vehicle detecting member.

In addition, another object of the present invention is to output the vehicle number information corresponding to the vehicle number in the same letter, number and color as the actual license plate of the vehicle, allowing the administrator to quickly and easily check the license plate of the departure. It is to provide a parking management system using a vehicle number recognition.

In addition, another object of the present invention is to provide a parking management system using a vehicle number recognition that can shorten the vehicle number recognition time by tying the license plate type according to the horizontal / vertical ratio, color and letter arrangement for a variety of license plates will be.

In addition, another object of the present invention is to provide a parking management system using a vehicle number recognition that can prevent negative parking time shortening and secure transparency of charge settlement.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

Figure 2 is a block diagram showing a parking management system using a vehicle number recognition according to a first embodiment of the present invention, Figures 3a and 3b schematically illustrates the entrance and exit of the parking lot is installed parking management system of Figure 2 4 is a block diagram showing the configuration of the number recognition fee payment device in the parking management system of FIG.

Parking management system using a vehicle number recognition according to a first embodiment of the present invention, as shown in Figures 2 to 4, the access management device 100 for controlling access to the vehicle entering and exiting the parking lot, the parking lot It is connected to the access management device 100 and the number recognition fee payment device 200 through the number recognition fee payment device 200 and the communication line to recognize the vehicle number by taking a picture of the number of vehicles entering and exiting the process and analysis the image; Parking control device 300 that enables the overall control of the parking management.

3A and 3B, the access control device 100 is installed at the entrance side of the parking lot, the parking ticket issuer 110 for issuing the parking ticket 400, and gates to allow the vehicle to enter the parking lot entrance. The entrance gate 120 that opens and closes, is installed at the exit side of the parking lot and is installed at the exit side of the parking lot and the parking ticket recognizer 130 that recognizes the parking information recorded on the parking ticket 400 (see FIG. 5). It includes an exit gate 140 for opening and closing the gate to be.

Here, the access control device 100, a signal control device consisting of a loop coil (Loop Coil) for detecting the position of the vehicle, a vehicle detector and various signals for detecting and guiding the movement of the vehicle, such as entrance indicators, departure notices, etc. It may further include.

As shown in FIG. 4, the number recognition fee settlement apparatus 200 analyzes an image photographed by the image photographing unit 210 and the image photographing unit 210 to continuously photograph the entrance and exit of the parking lot in real time. The vehicle number information corresponding to the vehicle number is determined by recognizing the vehicle number from the vehicle image stored in the image reader 220 and the image reader 220 to determine the entrance and exit of the parking lot and convert the image corresponding thereto into the corresponding vehicle image. Number recognition unit 230 to generate a, parking fee calculation unit 240 to calculate the parking fee to generate the parking fee information, vehicle image of the image reading unit 220, vehicle number information of the number recognition unit 230 and The parking fee of the data processing unit 250 and the number identification unit 230 and the parking fee calculation unit 240 for processing the parking fee information of the parking fee calculation unit 240 and compare and store it with previously stored registered vehicle information. Print information on parking ticket 400 The parking ticket printing unit 260, the photographing image of the image capturing unit 210, the vehicle image and driver image of the image reading unit 220, the vehicle number information and parking fee calculation unit 240 of the number recognition unit 230 And a display unit 270 for displaying parking fee information in a corresponding area, and a controller 280 electrically connected to the components to control the components.

The image photographing unit 210 is installed at a predetermined position on the entrance side of the parking lot, and the vehicle photographing camera 211 and the vehicle photographing camera 211, which are CCTV cameras for photographing an analog image of a vehicle entering the entrance of the parking lot. It is installed at the lower part of the shooting angle adjusting member (not shown), such as a tilt to change the shooting angle of the camera and the parking ticket issuer 110 and the parking ticket recognizer 130 are installed at a predetermined position to issue and collect the parking ticket 400. And a driver photographing camera 213 which is a CCD camera photographing the driver of the vehicle when the corresponding button is input (or when the vehicle is detected by the loop coil sensing the position of the vehicle).

Therefore, since the image photographing unit 210 continuously photographs the entrance and exit of the parking lot in real time without installing a sensor or a loop for detecting a vehicle entering the parking lot, a problem that may occur when the sensing means is employed. For example, it is possible to prevent the license plate of the vehicle from being clearly photographed due to limited photographing conditions such as weather irregularities or obstacles.

In addition, since the vehicle photographing camera 211 having a lower price than that of the digital camera is used as the equipment for photographing the vehicle, the cost can be saved.

In addition, the photographing angle of the vehicle photographing camera 211 can be automatically set periodically or periodically through the photographing angle adjusting member so that the license plate of the vehicle is not clearly photographed due to limited photographing conditions such as weather irregularities or obstacles. Can be prevented.

In addition, since the image of the driver of the vehicle entering and exiting the parking lot is photographed through the driver photographing camera 213, the identity of the driver of the vehicle is secured when the vehicle is a stolen vehicle or the wanted vehicle. You can be faithful.

Here, the vehicle imaging camera 211 and the driver imaging camera 213 are diffuse reflections to prevent the license plate of the vehicle or the driver of the vehicle from being clearly photographed due to backlight or diffuse reflection caused by headlights or sunlight of the vehicle. It is preferable to further provide a backlight blocking means (not shown) such as a filter or a polarizing filter.

The image reading unit 220 detects the movement of the vehicle entering the doorway of the parking lot by comparing analog images continuously captured by the vehicle photographing camera 211 of the image capturing unit 210 in real time. A motion detection algorithm is used.

The motion detection algorithm may include converting an analog image photographed by the vehicle imaging camera 211 into a digital image and dividing the analog image into individual frames (for example, 30 frames per second). Sequentially comparing each other, determining whether a vehicle enters an entrance and exit of the parking lot when the image of one frame and the next frame are different from each other; branching, bending, Extracting curved and shaded lines, deleting frames from which branches, bends, curved and shaded lines of the shape are extracted, and digitally converting frames in which the image of the vehicle is most clearly displayed among the undeleted frames. Storing as a vehicle image for the vehicle.

On the other hand, in order to improve the recognition rate of letters and numbers in the serial number of photographs and to reduce the recognition time, the image reading unit 220 is further provided with a storage medium (not shown) for storing the type of the license plate shape, letters, numbers desirable.

In this case, when a shadow or an obstacle is photographed in the license plate among a plurality of frames, when there is no data that matches the license plate standard (for example, the width / vertical ratio of the license plate) stored in the storage medium before the vehicle number is recognized. If the license plate of the standard specified in the next frame is matched without entering the vehicle number recognition step, it is preferable to enter the vehicle number recognition step.

Accordingly, the image reading unit 220 removes a frame damaged by noise or shadow among the frames of the image captured by the vehicle using the motion detection algorithm, and then, among the remaining frames, the frame having the clearest image of the vehicle is displayed on the vehicle. Because it stores as a vehicle image, it is possible to quickly process the analog image taken in real time to prevent overload.

 Therefore, the vehicle can be detected without installing a sensing means such as a sensor or a loop for sensing the vehicle entering the parking lot, thereby eliminating the trouble of installing the sensing means and saving the installation cost.

In addition, the image reading unit 220 stores a driver image of the driver of the vehicle photographed by the driver photographing camera 213.

The number recognition unit 230 generates vehicle number information corresponding to the number of the vehicle by using a license plate recognition algorithm from the image of the vehicle stored in the image reading unit 220.

Here, the license plate recognition algorithm is a vehicle number area extraction step of extracting a vehicle number area by examining the entire area of the vehicle image, a pre-processing / binarization step of preprocessing and binarizing the vehicle number area; Text (number string) / color gamutation step of extracting the number area and color gamut by removing area noise from the preprocessed and binarized images and using area analysis, and converting the data subjected to the character string / color gamutation step into actual characters / And a character / color array recognition step of recognizing the character / color of the vehicle number and its arrangement according to a specific value of the character / color stored in the color recognizer.

Accordingly, the vehicle number information generated by the vehicle number recognition algorithm includes character / numeric string data for the vehicle number and color data for the vehicle license plate in the same arrangement as the actual license plate of the vehicle is reduced.

On the other hand, the vehicle number area extraction is preferably made of the following steps.

end. Find the number and position of edges for a row processed by the differential operator.

I. Rows that do not satisfy the conditions of the minimum number of edges and the maximum number of edges in the number area are ignored.

All. Since the characters in the numbered area have a constant width, the distances between the characters and the characters in the line where the number of edges are satisfied are merged to merge the characters in the constant distance.

la. The merged size is compared to meet the minimum and maximum size of the license plate size.

hemp. If the merged size matches the size of the license plate, it finds successive rows with regular intervals satisfying the above conditions and extracts them into the license plate area.

The parking fee calculation unit 240 automatically calculates the fee for use of the parking lot corresponding to the difference in the generation time of the vehicle number information generated at the time of arrival and the vehicle number information generated at the time of departure among the vehicle number information of the number recognition unit 230. To generate parking fee information.

The data processing unit 250 compares and analyzes the vehicle number information of the number recognition unit 230 with information corresponding to a pre-stored regular parking vehicle (or a registered vehicle) or visitor vehicles input from the outside, and thereby analyzes the vehicle recognition list information. Create

The parking ticket printing unit 260 prints vehicle number information generated by the number recognition unit 230 in addition to the basic parking information, that is, serial number, entering date, and entering time, at a predetermined position of the parking ticket 400.

5 is a view showing a parking ticket in the parking management system of FIG.

Parking ticket 400, as shown in Figure 5, includes a vehicle number printing unit 410, which is a space in which the vehicle number information is printed, the vehicle number information is the same as the actual number plate of the vehicle is reduced String data and color data are arranged to have a shape.

Therefore, since the vehicle number information is printed on the parking ticket 400 in the same shape as the actual license plate of the vehicle, a manager checks the license plate of the vehicle when the vehicle is released (the vehicle number information includes color data). Therefore, it is possible to determine whether the license plate of the vehicle is green or yellow) quickly and accurately.

The display unit 270 includes a monitor device that allows a manager to supervise parking management for a vehicle entering and leaving the parking lot.

Hereinafter, a parking management method using vehicle number recognition according to a first embodiment of the present invention will be described in more detail.

7A and 7B are control flow diagrams showing the entering and leaving process of a vehicle, respectively, in the parking management method using vehicle number recognition according to the first embodiment of the present invention.

First, the process of entering the vehicle in the parking lot will be described as follows.

As shown in FIG. 7A, the entrance of the parking lot is continuously photographed in real time by the vehicle photographing camera 211 of the image photographing unit 210 installed at the entrance of the parking lot (S 600).

Thereafter, the image reading unit 220 compares the analog image photographed by the vehicle photographing camera 211 in real time using a motion detection algorithm, and determines whether the vehicle enters the entrance of the parking lot (S605).

Then, if it is determined that the vehicle is in the entrance of the parking lot (S 610), the image reading unit 220 converts the analog image to the corresponding digital image and the image of the vehicle of the most clear image of each frame It stores as the vehicle image (S 615).

Thereafter, the number recognition unit 230 generates vehicle number information corresponding to the number of the vehicle using the vehicle number recognition algorithm from the vehicle image of the image reading unit 220 (S620).

Thereafter, the data processing unit 250 compares and analyzes the information of the regularly stored parking vehicle (or registered vehicle) based on the vehicle number information of the number recognition unit 230 (S625).

Thereafter, if it is determined that the vehicle is a regular parking vehicle (S 630), the entrance gate 120 of the access control apparatus 100 installed at the entrance side of the parking lot is opened and the vehicle enters the parking lot (S 635). .

If it is determined that the vehicle is not a regular parking vehicle (S 630), the vehicle number generated by the number recognition unit 230 in the vehicle number printing unit 410 of the parking ticket 400 by the parking ticket printing unit 260 The information is printed together with the basic parking information (S640).

Thereafter, the parking ticket 400 is issued by the parking ticket issuer 110 of the access control apparatus 100 installed at the entrance side of the parking lot (S645).

Subsequently, when the parking ticket 400 is issued from the parking ticket issuer 110, the driver image of the vehicle is photographed by the driver photographing camera 213 of the image photographing unit 210 installed in the parking ticket issuer 110, and the image reading unit 220. Is stored by (S650).

In other words, the image of the external vehicle driver is photographed by the driver photographing camera 213 facing the driver's window at the moment when the external vehicle driver who opens the window and receives the parking ticket 400 when the parking vehicle enters the parking lot. .

In operation S 635, the vehicle enters a parking lot.

Therefore, when the vehicle entering the parking lot is a regular parking vehicle, the process from step S 640 to step S 650 may be omitted, thereby preventing a vehicle rolling phenomenon when the vehicle is entered.

Meanwhile, the process of leaving the vehicle in the parking lot will be described below.

As illustrated in FIG. 7B, the exit of the parking lot is continuously photographed in real time by the vehicle photographing camera 211 of the image photographing unit 210 installed at the exit side of the parking lot (S 700).

Thereafter, the image reading unit 220 compares the analog image photographed by the vehicle photographing camera 211 in real time using a motion detection algorithm, and determines whether the vehicle enters the exit of the parking lot (S 705).

Then, when it is determined that the vehicle is discharged to the exit of the parking lot (S 710), the image reading unit 220 converts the analog image into the corresponding digital image and the image of the image of the vehicle among the most clear image The image is stored as the vehicle image (S 715).

Thereafter, the number recognition unit 230 generates vehicle number information corresponding to the number of the vehicle using the vehicle number recognition algorithm from the vehicle image of the image reading unit 220 (S 720).

Subsequently, the data processing unit 250 compares and analyzes the information of the pre-stored regular parking vehicle (or registered vehicle) based on the vehicle number information of the number recognition unit 230 (S 725).

Then, when the vehicle is determined to be a regular parking vehicle (S730), the exit gate 140 of the access control device 100 installed on the exit side of the parking lot is opened and the vehicle leaves the parking lot (S735). .

If it is determined that the vehicle is not a regular parking vehicle (S730), the parking ticket 400 is collected by the parking ticket recognizer 130 or the manager of the access control apparatus 100 installed at the exit side of the parking lot (S740). ).

Thereafter, the parking fee calculation unit 240 calculates the time difference between the vehicle number information generated when entering the vehicle and the vehicle number information generated when leaving the vehicle, and calculates and collects the fee of the parking lot corresponding thereto. (S 745).

Here, the step S 740 may be omitted by step S 745, but the step S 740 may include the parking ticket 400 to prevent the driver of the vehicle from being issued a parking ticket again in an unfair manner before leaving the vehicle in order to save a parking fee. The parking information printed on the) and the vehicle number is for a check operation for comparing the vehicle number information generated when entering by the number recognition unit 230.

In addition, the parking fee is settled through the magnetic serial number of the parking ticket 400 issued at the time of departure and whether the vehicle number information is the same at the time of leaving the vehicle when the fee for the parking lot is settled in step S 745. It is desirable to.

Subsequently, when the parking ticket 400 is collected by the parking ticket recognizer 130 or the manager, the driver image of the vehicle is taken by the driver photographing camera 213 of the image photographing unit 210 installed in the parking ticket recognizer 130 to read the image. It is stored by the unit 220 (S 750).

In other words, the image of the external vehicle driver by the driver photographing camera 213 facing the driver's window at the moment when the parking ticket 400 is collected by the parking ticket recognizer 130 by the external vehicle driver when the parking lot is discharged. Will be taken.

In operation S 735, the vehicle leaves the parking lot.

Therefore, when the vehicle leaving the parking lot is a regular parking vehicle, the process from step S 740 to step S 750 may be omitted to prevent the vehicle from rolling out when the vehicle is taken out.

On the other hand, when entering and leaving the vehicle in the parking lot, stored in the image, the image reading unit 220, the image taken by the vehicle camera 211 at a predetermined position of the display unit 270 installed in the space where the manager works The image of the vehicle, the image of the driver, the vehicle number information corresponding to the image of the vehicle and the vehicle recognition list are displayed in real time, so that the administrator can more conveniently check the parking management situation with the naked eye (for example, parking ticket ( Vehicle number information printed on the display 400 and the vehicle number information displayed on the display unit 270).
