8 is a block diagram showing the internal configuration of the parking management server 100 shown in Fig. 2 functionally separated.

8, the parking management server 100 includes a first communication connection unit 110, an imaging image processing unit 120, a service control unit 130, a database 140, and an information input / output unit 150 . Here, each of the devices may be coupled via a LAN (Local Area Network) 160, for example. In addition, each of the devices may be constituted by one server or may be configured by a plurality of devices.

The first communication connection unit 110 performs IP communication with the parking information input / output module 200 through the hub 300. That is, the first communication connection unit 110 converts the IP signal provided through the hub 300 into a signal suitable for the parking management server 100, converts the signal of the parking management server 100 into an IP signal And provides the parking information to the parking information input / output module 200 through the hub 300.

The photographed image processing unit 120 analyzes the photographed image provided through the first communication connection unit 110. That is, the photographed image processing unit 120 converts the input distorted photographed image into a planar divided image including a parking plane and an input / output lane, and reads the vehicle number from the divided image of the converted parking plane. Here, the photographed image processing unit 120 recognizes the vehicle number by extracting characters of the entire license plate from the converted divided images based on the optical character recognition (OCR) technology, which is an image recognition and image reading technology. At this time, as a method of transforming a distorted image, a known image correction method such as forward mapping, interpolation and inverse mapping through application of a correction coefficient can be applied. In addition, the photographed image processing unit 120 stores the divided images converted into the planar shape in the database 140. FIG.

The service control unit 130 controls overall operation of the present parking management system. That is, the service controller 130 provides the parking space availability information for the corresponding parking information input / output module 200 based on the image analysis information provided from the photographed image processing unit 120. For example, the service control unit 130 reads the vehicle number from the divided image of the parking surface, determines that the vehicle number is read when the vehicle number is read, and determines whether the first or second If the number of the maximum number of vehicles to be parked is the same as the number of the vehicles judged to be in the parking state, generates the vehicle state information and provides it to the parking information input / output module 200 side. If the maximum number of parking vehicles is "3 ", the number of vehicles judged to be in the parking state is" 1 ", and the maximum number of parking vehicles is large, the service control unit 130 stores the tolerance state information including the tolerance number, And provides it to the parking information input / output module 200 side. If the parking status information is changed, the service control unit 130 updates the database 140 based on the changed parking status information.

In addition, the service control unit 130 sets the vehicle number recognition time for the vehicle number as the entry time, provides the time when the vehicle number is recognized and converted into the non-recognition state as the departure time, and provides it to the database 140 . At this time, the service control unit 130 stores the parking lot area information corresponding to the installation position of each parking information input / output module 200 in advance, and stores the position information of the parking lot information input / output module 200, And stores the parking position information determined on the basis of the parking surface position information in the database 140. For example, when the first parking surface photographed by the parking information input / output module 200 is in the area between the parking positions A1 and A2 and the second parking surface is in the area between B1 and B2, In case of the parking area corresponding to the second parking face, the service control unit 130 judges the parking position as "B1" for the corresponding car number.

In addition, the service control unit 130 divides the photographed images of the first parking surface, the second parking surface, and the entry / exit lane in the photographed image, and stores the divided images in the database 140.

The database 140 stores photographed images provided by the photographed image processing unit 120. [ At this time, the database 140 stores the parking time image and the I / O lane image according to the shooting time so as to correspond to the parking information input / output module 200 identification information. Here, the parking plane image and the I / O lane image are preferably stored in different storage areas. In addition, the database 140 stores an entry time, a departure time, and parking position information so as to correspond to a car number.

The information input / output unit 150 inputs various kinds of information related to parking management and outputs various information related to parking management. That is, the manager searches / confirms various kinds of parking related information stored in the database 140 through the information input / output unit 150 and performs various control commands for the parking management such as initialization of the parking information input / output module 200 And drive setting, and confirms the result.

Next, the operation of the parking management system configured as described above will be described.

First, a plurality of parking information input / output modules 200 are installed at a certain distance from the upper center portion of an entrance and exit of a parking lot. At this time, the parking information input / output module 200 is installed at a position where both side parking faces for at least one vehicle and photographing of an entrance and exit lane corresponding to the parking side are possible. For example, the parking information input / output module 200 may be configured to photograph the first and second parking faces S1 and S2 corresponding to the parking areas of the three vehicles.

At this time, IP information is allocated to the parking information input / output module 200, and IP information for each parking information input / output module 200 is set and registered in the database 140 as an identification code. In the database 140, parking code information and parking status information corresponding to the shooting parking surface for each identification code of the parking information input / output module 200 are stored.

In the above-described state, the video photographing apparatus 220 of the parking information input / output module 200 photographs the image of the parking surface to which the parking position information is assigned and provides it to the parking management server 100. At this time, the image photographed by the image photographing apparatus 220 corresponds to the shape of the mirror constituting the image photographing apparatus 220. For example, when the mirror 225 is hemispherical as shown in FIG. 7, a distorted photographed image of the type shown in FIG. 9A is provided to the parking management server 100.

The parking management server 100 stores a distorted photographed image as shown in Fig. 9A, which is provided from the parking information input / output module 200, to a parking lot including the parking spaces S1 and S2 and the entrance and exit lanes T1 and T2 And divides the converted divided images into the areas of the parking spaces S1 and S2 and the areas of the entrance and exit lanes T1 and T2 and stores them in the database 140. [ At this time, the photographed images of the incoming and outgoing lanes T1 and T2 may be combined and stored as one image. This is to secure enough images of minor accidents that may occur when entering or leaving the vehicle. In addition, the parking management server 100 analyzes the vehicle number in the converted parking plane divided image, and updates the parking status information based on whether the vehicle number is recognized.

When the parking status information on the corresponding parking surface is changed, the parking management server 100 loads the changed parking status information into the parking information input / output module 200 IP information of the parking surface, 200 side.

When the parking related information is inputted from the parking management server 100 side, the parking information input / output module 200 reads only the data including the own IP information and provides the remaining parking related information to the other parking information input / output module.

Also, the parking information input / output module 200 drives and controls the pneumatic lamp 230 based on the parking related information provided from the parking management server 100 side. That is, the full differential voltage ramp 230 is displayed as "red" for the full-state information, and displayed as "green" for the tolerance state information.

That is, according to the embodiment, it is possible to easily acquire a photographed image of a parking surface and an entrance / exit lane using a simple and low-cost image capturing apparatus, and it is possible to easily provide parking management.

In addition, the administrator can provide the parking method service to the user by checking the photographed image stored in the database through the information input / output unit.

On the other hand, in the present invention, an induction electric signboard for guiding parking guidance of a vehicle may be additionally provided on the upper side of an entrance / exit lane.

That is, as shown in FIG. 10, an induction electric sign board 500 for guiding a tolerance space with respect to a parking space managed by at least two parking information input / output modules 200 is installed in the corresponding parking area, The electric sign board 500 is coupled to the parking information input / output module 200 installed in the corresponding parking area. At this time, the guidance electric sign board 500 receives parking guide information provided from the parking management server 100 through the corresponding parking information input / output module 200.

Also, the parking management server 100 generates parking guide information based on the door condition information provided from the parking information input / output module 200 coupled with the induction electric sign board 500, Output module 200 through the IP information of the parking information input / output module 200 to which the vehicle information 500 is connected. Here, the parking induction electric signboard 500 may include information on the number of "free parking spaces" in numerical form for the parking area and parking direction information in the form of an arrow (→).
