{Parking Guidance System using IP camera}

The present invention relates to a parking induction system to which an image technique of an IP camera is applied, and relates to a parking induction system capable of efficiently installing an image technology of an IP camera in a parking system, thereby improving economical efficiency and facility easiness.

In modern society, automobiles are no longer classified as luxury goods because of the development of various technologies and the improvement of living standards. Especially, as the small family is increasing rapidly due to the nuclear family and the leisure time is becoming a big issue due to the continuous decrease of working hours, the automobile as travel means such as travel or shopping is no longer a luxury item .

As reflected in this point, when looking at weekends or holidays, the roads in the city are rather hansan compared to the weekdays, while the roads around large shopping malls, discount stores, and department stores are reminiscent of parking lots. In the end, for modern people, automobiles play a role as part of necessities that are not necessary like mobile phones.

However, there is a convenient and beneficial use of the car as a necessity, but on the back of it, parking is becoming a big social problem due to the increased number of vehicles compared to the limited parking space.

Especially, when a user intends to enter a parking lot such as a large shopping mall, a discount store, or a department store by using a car, there may have been many times that he /

Large buildings such as department stores, large shopping centers, and hospitals where flood-prone populations are generally equipped with large parking facilities that provide multiple parking spaces. In the case of parking a floating vehicle in this way, since each parking space is not assigned to a specific person, the driver searches for a parking space that is not occupied and wanders inside the parking lot, thereby creating valuable time, waste of fuel, There are many cases. In addition, in many large parking lots, it takes a lot of inefficiency and unsanitary waste processes to hire a lot of parking induction manpower to make it a parking assistant in a poor environment parking lot, and the waste and inefficiency This is common.

Accordingly, by allowing the driver to easily grasp information on the unoccupied parking space, it is possible to save valuable parking time, waste fuel, and also to improve the environment.

Particularly, in the case of a plurality of layers such as a large parking lot, it is possible to check how many parking spaces are left in the floor entryway of each floor, and also to check the unoccupied parking Capacity parking induction management server system capable of recognizing the space in advance.

However, because of the disadvantage that high cost is invested in complex signal communication construction, application is limited except for large complex parking lot. Therefore, in a small parking lot, a system capable of efficiently inducing parking without an expensive high-capacity parking induction system is required.

The parking guidance system to which the video technology of the IP camera according to the present invention is applied comprises a parking guidance system for obtaining vehicle information and implementing parking guidance using a dual stream technique of an IP camera in a parking lot that provides a parking space for a vehicle The main technical point is to provide reliability and ease of installation through efficient arrangement of cameras and establishment of overall facility specifications.

1A is a plan view of a parking induction system to which an imaging technique of an IP camera according to the present invention is applied.

The parking guidance system according to the present invention recognizes the information of the vehicle through the IP camera 100 to confirm whether or not the vehicle 300 is parked and ultimately recognizes the license plate of the vehicle so that the user can recognize the position A parking lot, a parking lot, a parking lot, a parking lot, etc.), a license plate of the vehicle is recognized through a camera and stored in a digital DVR or NVR. When the user requests a license plate, The user can search for the position of the vehicle and can promptly park the vehicle by guiding the area through the electric sign board so that the vehicle entering the parking space 200 can quickly park the vehicle in an empty parking space. will be.

Here, in order to recognize the information of the vehicle installed in each parking space, an IP camera is installed for each parking area, and a parking guide is implemented by capturing an image of a parked vehicle, acquiring and storing an image, and then extracting an image.

In this case, the camera can be implemented in the lateral parking space to acquire images of the parked vehicle, and the lateral parking space means a parking space in which the front or rear surface of the vehicle is arranged side by side. Conversely, The case means a general parallel parking.

Therefore, in the present invention, in order to recognize the information of the parked vehicle in the parking lot provided with the lateral parking space, the camera is installed on the parking space reference surface opposite the parking space of the vehicle, and information of the facing vehicle is obtained. In other words, in the parking reference plane, the vehicle information is captured as an image by photographing a parked vehicle in the opposite parking space on the ceiling of the reference surface of the facing parking space facing the front end of the lateral parking space.

In consideration of the optical characteristics of the camera of the present invention, in order to secure the maximum photographing range and photographing accuracy, a vehicle is installed within a range of at least 4 to 10 meters, The information acquisition range is configured to acquire images only for a total of five vehicles including one vehicle at the center and two vehicles at both sides based on the location where the camera is installed. 10 m, distortion occurs due to the functional characteristics of the camera, specifically the lens characteristics, and the distorted image information deteriorates the vehicle discrimination power. Therefore, the present invention determines the position of the camera under the above conditions.

FIG. 4 shows an example in which the camera is installed on the parking reference plane in the case of FIG. 1 according to another embodiment of the present invention, but the center installation formula will be described. In the case of the central installation type, it is installed at the center of the moving parking space of the vehicle. In more detail, it is installed between the facing parking spaces to acquire the vehicle information. At this time, the camera has a structure capable of acquiring all the vehicle information installed in the facing parking space as a rotary type or a double-sided type. At this time, the installation distance of the camera can be set in the range of 2 to 5 meters with respect to the parking reference plane of both parking spaces, which is preferably determined in the parking lot design, and in the case of the parking lot already constructed, Should be structurally complemented so that a distance of 2 to 5 m can be satisfied on both sides.

FIGS. 5 and 6 are views showing the construction of an electrical signal line according to the present invention. In the present invention, an electrical signal (power supply, signal) can be applied to the camera in two forms.

In the case of FIG. 5, the power supply line 130 and the signal line 120 are separately supplied by a single cable in the POE system. In FIG. 6, the power supply line and the signal line are separately supplied. In this case as well, the cables are placed in the inner space of the structural frame to install the camera.
