Description

PLAY BACK TYPE CAR NUMBER RECOGNITION STREET PARKING SYSTEM WITH SECURITY FUNCTION AND METHOD FOR CONTROLLING THEREOF}

The present invention relates to a vehicle number recognition roadside parking system having a security function and a control method thereof. More specifically, the present invention is installed in an outdoor environment in which lighting conditions are inferior to an indoor environment as needed, and selectively uses infrared light and visible light lighting that are essential for day and night security images and license plate recognition, and parking vehicle. It has a security function to record the road and parking lot in front of the entrance and parking lot without any blind spot and store the recorded video.If the vehicle number recognition is not completed when entering or leaving the vehicle, the image of the section where the vehicle number is visible And a vehicle number recognition roadside parking system for repeatedly recognizing and preventing partial recognition or unrecognition.

Due to the increasing number of vehicles, the parking shortage is a serious problem, and it is expected that a large number of parking lots will be created in the future to solve the increasing parking shortage.

In this case, the parking lot may be classified into a roadside parking lot installed on a road surface or a certain area of a traffic plaza, an off-street parking lot installed on a road surface or a place other than a traffic plaza, and an attached parking lot installed along with a facility that causes parking demand, such as a building. Such parking lots may be classified as either manned or unmanned.

In this case, the incentive method requires an employee to be arranged for the settlement of the fee, so there is a problem that excessive labor costs are required and there is a possibility of incurring charge leakage due to the misuse of the inducement collection.

In addition, in the case of the roadside parking lot, since the fixed fee settlement that controls the entire parking lot cannot be installed, it may be difficult for an employee to efficiently manage the whole parking lot when the management area is large.

On the other hand, in the case of the unmanned parking lot, the off-road parking lot and the attached parking lot are limited to the entrance and exit, so it is easy to manage the unmanned parking lot by controlling the entering and exiting vehicles with a breaker, etc. Due to its characteristics, there is a problem in that it is difficult to control the entering and exiting vehicle easily.

In order to solve the problem of the roadside parking lot, as disclosed in FIG. 1A, the unmanned roadside parking lot frequently uses a flap control scheme.

Here, the flap control method prevents unauthorized vehicle leaving until the parking settlement is completed by restraining the vehicle by raising the flap from the floor of the parking lot when the vehicle is parked.

However, since the flap control method occupies the largest part of the parking lot creation and operation costs, the flap control method increases the parking lot creation and operation costs. In addition, the flap control scheme may cause a feeling of rejection to the parking lot user because the fee is not voluntarily collected by force.

Accordingly, as disclosed in FIG. 1B, a vehicle number recognition type roadside parking lot unmanned settlement system capable of operating without personnel from entering to leaving of the vehicle has been used.

However, this open parking lot unmanned settlement system is easy to shoot each vehicle, but to shoot the entire parking lot, you need to use a separate CCTV, there is a blind spot that CCTV can not shoot, difficult to settle the parking fee at night, If there is no lighting device, there is a problem that the security function is vulnerable. Therefore, a lighting device capable of capturing and storing a video of the security video even at night and recognizing the vehicle number when entering the vehicle is required.

In addition, since the vehicle is parked close to the camera after entering, the license plate becomes invisible. If the vehicle number recognition is partially recognized or unrecognized at the time of entry, a solution for this is required.

Referring to FIG. 3, a playback type vehicle number recognition street parking system 1 having a security function includes an integrated management center 10, a plurality of zone management servers 21, 22,..., 2N, and a plurality of sensor units. 3,..., 3N, a plurality of cameras 41,..., 4N, and an unmanned rate calculator 50. However, since the components shown in FIG. 3 are not essential, a parking system having more components or fewer components may be implemented.

For convenience of description, the description of the integrated management center 10 and the plurality of zone management servers 21, 22,..., 2N of the roadside parking system 1 described in FIG. 2 will be omitted.

In addition, the configuration of the present invention will be described centering on the first zone management server 21 among the plurality of zone management servers 21, 22,..., 2N. However, it is obvious that the configuration and effect described in the first zone management server 21 can be applied to other zone management servers 22, ..., 2N.

The first zone management server 21 may include a first sensor unit 31, a first camera 41, and an unmanned fare calculator 50.

First, the first sensor unit 31 provides a function of detecting an entering vehicle and an exiting vehicle.

The first sensor unit 31 detects the current state of the vehicle in the first parking lot such as the entry / exit state of the vehicle in the first parking lot, the position of the vehicle, the presence or absence of user contact, the orientation of the vehicle, the acceleration / deceleration of the vehicle, and the like. A sensing signal for controlling the operation of the parking system 1 is generated.

In addition, although not shown, it is possible to sense whether or not the power supply of the power supply, etc., the first sensing unit 31, each of the proximity sensor, image analysis sensor, etc., each of the individual functions or includes a module unit including each function Can function.

On the other hand, the first camera 41 processes image frames such as still images or moving images obtained by the image sensor in the shooting mode.

The processed image frame may be displayed on the display unit of the street parking system 1 although not shown.

The image frame processed by the first camera 41 may be stored in a memory inside the controller or transmitted to the outside through a wireless communication unit.

In addition, two or more first cameras 41 may be provided depending on the use environment.

The wide-angle camera 41 applied to the present invention is a camera using a wide-angle lens. The wide-angle lens is a kind of camera lens, which means that the focal length is shorter than the length of the screen diagonal.

Wide-angle lenses provide a wider field of view than standard lenses, so they are mainly used for shooting landscapes with a wide field of view from far-field to near-field.

In addition, the wide-angle lens is characterized by enlarging a narrow space, exaggerating perspective and making a moving subject appear to move faster as it approaches the camera.

This is particularly called a wide-angle effect, and the screen using the wide-angle lens is called a wide-angle screen.

In addition, the existing number recognition street parking system has a problem in recognizing the vehicle number because the vehicle number is not reflected on the camera when the vehicle is parked when the vehicle number recognition is not completed when the vehicle enters or leaves the parking compartment.

However, in the present invention, when the vehicle number recognition, such as partial recognition or unrecognition, is not completed when entering or leaving the vehicle, play with a security function that prevents unrecognition by repeatedly replaying and recognizing the image of the section where the vehicle number is visible among stored images. A bag type vehicle number recognition street parking system is applied.

Returning to FIG. 3 again, the vehicle number recognition street parking system 1 having the security function proposed by the present invention may include an unmanned fare checker 50.

Here, the unmanned tariff setter 50 may include a controller inside the setter or link the recognition data from the controller to integrate the parking fee for all parking surfaces in the parking lot.

The unmanned fare calculator 50 is connected to the zone management server of the corresponding zone and is connected to a plurality of zone management servers 21, 22, ..., 2N.

When the parking lot user enters the vehicle number in which his vehicle is parked, the unmanned fare checker 50 calculates the entrance time of the detected vehicle in the connected parking compartment, the parking time from the entrance time to the current time, and the vehicle time calculated from the parking time. The parking fee, the image taken when entering the vehicle, the vehicle number extracted from the image of the vehicle, etc. can be output. In addition, if there is additional data such as the parking fee unpaid amount, if the vehicle is received from a plurality of zone management server (21, 22, ..., 2N) and displayed on the screen. In addition, the parking lot user can enter their own four-digit vehicle number.

When the user inputs the vehicle number, the unmanned fare checker 50 is currently parked from the parking surface on which the vehicle corresponding to the input number of the parked vehicles is parked, the entrance time of the vehicle detected by the sensor unit 31, and the entrance time. The parking time until the time, the parking fee of the vehicle calculated from the parking time, the image taken by the camera 41 at the time of arrival, the vehicle number extracted from the image of the vehicle and the like are displayed on the screen.

When a plurality of vehicles having an input number are parked, the unmanned fare calculator 50 may select a parking surface on which the user's vehicle is parked from among parking surfaces on which the vehicle having the input number is parked.

In this case, the unmanned fare checker 50 may display a picture, a parking time, a parking time, an image, etc. of the vehicle parked on each parking surface, so that the user can easily select it.

In addition, when the unmanned parking fee is in the vehicle corresponding to the previous user, the unmanned fee checker 50 may receive the fee from the zone management servers 21, 22,.

In addition, after checking the contents displayed on the screen, the user pays the parking fee using commercially available means such as cash, credit card, and traffic card.

The unmanned fare checker 50 may further include an internet phone to enable two-way communication between the parking lot user and the manager of the integrated management center 10.

When a problem occurs in the parking fee settlement process, the user can solve the problem using an Internet phone.

On the other hand, the function of the above-described unmanned tariff 50 may be provided through the first camera 41 proposed by the present invention in the same way.

A detailed description thereof will be described in detail with reference to FIG. 6.

Although not shown, the controller 180 may be further provided separately.
