BEST MODE FOR THE INVENTION
Hereinafter, preferred embodiments of the present invention will be set forth in detail with reference to the accompanying drawings.
FIG. 1 schematically illustrates various services offered by a parking control system in accordance with the present invention.
Referring to FIG. 1, the present invention provides a parking control system and method which enable an automatic management and control from a time when a vehicle enters a parking lot to a time when it gets out of there by using a server that incorporates therein a very high speed image recognition technique and a parking management program. For this, the present invention employs a parking position search system which manages parking positions of individual vehicles by identifying vehicle numbers by means of photographing vehicles that enter the parking lot and get out of there as well as parked vehicles, and offers the required information upon searching thereof. The present invention further uses a parking guidance system that guides a driver of a vehicle entering the parking lot to an empty space available for parking. In the foregoing description, if a vehicle number is not identified for an arbitrary parking space, it can be identified as an empty zone available for parking. Further, in addition to identifying the number of vehicles entering the parking space and getting out of there, the present invention adopts an accident confirmation system which photographs the appearance of each of the vehicles and storing the photographed images therein for accident confirmation during the parking. Besides, the present invention employs a long-term parking vehicle management system, and also uses a vehicle protection system for photographing the parked vehicles and storing the photographed images. Also, the present invention adopts a guidance system for vehicles getting out of the parking lot for notifying the drivers of the vehicles of status of each of a plurality of centers for settlement of a parking fee and conditions of outside road. Finally, the present invention has a structure that can monitor the parked vehicles by connection with wire/wireless network including the Internet and the like, and remotely control and repair the parking system when a trouble happens therein.
FIG. 2 illustrates an overall structure of the parking control system in accordance with a preferred embodiment of the present invention.
Referring to FIG. 2, the parking control system basically includes a photographing unit 100 for photographing vehicles entering a parking lot, a photographing unit 200 for photographing vehicles getting out of there, a parking status guidance screen 610, an inner photographing unit 300 and a server unit 500.
The photographing unit 100 for photographing vehicles entering the parking lot and the photographing unit 200 for photographing vehicles getting out of there preferably include sensors 104 and 204 for sensing vehicles A and C entering the parking lot and getting out of there, for example, sensors such as infrared rays sensors, cameras 102 and 202 for photographing vehicles entering the parking lot and getting out of there in response to signals sensed by the sensors 104 and 204, and vehicle number identifying modules, respectively. Each of the vehicle number identifying modules employs a technique that identifies images at a very high speed, that is, captures and scans images and identifies characters therefrom. In addition, there is the use of a technique of selecting an identification object region from the whole captured images. Preferably, the vehicle number identification modules may be included in control boxes 101 and 201 having an image capture board, an image control board and an identification software. These control boxes 101 and 201 may be embedded in a separate PC or in the server unit 500 to be described later. Further, these control boxes 101 and 201 may be configured with a control box 301 of the inner photographing unit 300 to be described later as a single body. Also, the control boxes 101, 201, and 301 may be structured together as a single body.
When vehicles A and C enter an entrance/exit for entry into the parking lot or exit therefrom, the sensors 104 and 204 first sense the status and then send a signal to each of the control boxes 101 and 201. The control boxes 101 and 201 operate the cameras 102 and 202 for photographing vehicles entering the parking lot and getting out of there, and identify the number, symbol or character of vehicle number plate. The identified number, symbol or character of vehicle number plate is sent to the server unit 500 and then stored therein. And, each of the photographing units 100 and 200 for photographing vehicles entering the parking lot and getting out of there may identify the vehicle number by identifying the movement of vehicles when there occurs a change by comparison of images after and before photographing without using the separate sensors 104 and 204.
Preferably, a plurality of appearance photographing cameras 103 and 203 for photographing the appearances of the vehicles A and C entering the parking lot and getting out of there are prepared at the entrance/exit. By such a structure, the appearance images of the vehicles entering the parking lot and getting out of there are compared, so that the appearance change of vehicles can be identified during the parking. Preferably, each of the appearance photographing cameras 103 and 203 is provided with at least 2 to 4 cameras for photographing vehicles in three dimensions on all sides. The images photographed by the appearance photographing cameras 103 and 203 are stored in the control boxes 101 and 201 or the server unit 500, or captured and then stored therein. This storage of appearance images photographed during the entry/exit of vehicles helps solve a problem of accidents that may happen during the parking. For instance, when a scratch occurs in a vehicle, the appearance images can be primarily used as judgment/evidence documents as to whether such a scratch occurs inside or outside the parking lot. Further, in case of synthetically comparing results of the inner photographing unit 300 to be described later, and records such as scratch direction and parking time, the causal relationship therebetween can be clarified more easily based on the appearance images.
Once the number of vehicle number plate, symbol or character is identified by the photographing units 100 and 200 for photographing vehicles entering the parking lot and getting out of there, the results are stored in a database prepared in the server unit 500. In this case, the total number of parked vehicles in the parking lot is updated in the database, and information about entry times of those vehicles into the parking lot is stored therein in real times. The server unit 500 may incorporate a parking management program therein, in addition to the database.
The inner photographing unit 300 is arranged to photograph at least current parking status and the identification information of a parked vehicle B every unit compartment within the parking lot. This inner photographing unit 300 is provided with a plurality of cameras 302 and a vehicle number identification module in the control box 301 as described above, wherein details thereof will be omitted for simplicity. The number, symbol or character of vehicle number plate so identified is stored in the database of the server unit together with the parking position.
FIG. 3 represents a parking status guidance screen for parking guidance provided in the parking control system in accordance with the present invention.
With reference to FIGS. 2 and 3, when a vehicle enters via an entrance, the parking management program provided in the server unit 500 displays unit compartments available for parking on the parking status guidance screen 610. Preferably, the unit compartments available for parking as well as layout are displayed, for example, in a red flicking manner. At this time, when the vehicle moves to a location available for parking, a bright light representing a space available for parking, for example, guidance light such as green light or white light is emitted, thereby readily finding out the space available for parking. By this structure, the driver can find out the empty space available for parking immediately, without wandering the parking lot. Moreover, in case of large parking, an additional effect of making smooth flow can be obtained automatically.
When parking is made in a parking unit compartment 700, the above-mentioned inner photographing unit 300 photographs and identifies a vehicle number of the parked vehicle B, and updates information stored in the database of the server unit 500.
The server unit 500 includes at least the database having the whole parking lot layout and a server incorporating the parking management program therein. Therefore, the server unit 500 receives and stores the photographed information containing image information from the photographing units 100 and 200 for photographing vehicles entering the parking lot and getting out of there, and receives and stores the photographed information having image information of the inner photographing unit 300. At least the vehicle numbers of vehicles entering the parking lot and getting out of there, parking times and parking positions as well as the image information are stored in the database based on the received photographed information. The parking management program extracts the individual unit compartments available for parking and information about the total number of currently parked vehicles from the stored information. These information stored in the database are preferably updated in real times. Further, it may be embodied in a manner that since the amount of data of the image information may be very large, the information is stored in the control boxes 101, 201 and 301 and only the residual photographed information is extracted and stored in the server unit 500.
FIG. 4 shows a search terminal employed in the parking control system in accordance with the present invention.
Referring to FIGS. 2 and 4, the parking control system of the present invention is provided with a plurality of search terminals, e.g., 900, coupled with the server unit 500. Through the search terminal 900, search information including at least parking position information on vehicles to be searched is provided upon input via a touch screen or by voice for search. The display screen of the search terminal 900 including a path for going to vehicles to be searched may be kiosk, PC, wireless terminal, home gate or home server. Further, the parking information may be preferably provided as voice information. Specifically, when a searcher inputs a vehicle number via an input unit of the search terminal 900, the parking lot layout in which parking positions of vehicles to be searched and a current position of the searcher are marked is displayed on the display screen of the search terminal 900. More preferably, a shortest path line connecting the two positions may be displayed together.
FIGS. 5A to 5D illustrate monitor screens of management terminals provided in the parking control system in accordance with the present invention.
Referring to FIGS. 2, and 5A, 5B and 5C, the parking control system of the present invention includes a plurality of management terminals 800.
The parking management program incorporated in the server unit 500 has a program code for multi-window function. Therefore, as depicted in FIGS. 5A and 5B, the management terminal 800 can be implemented in at least multi-display screens using GUI map. With respect to a plurality of parking zones, multi-display and/or multi-tasking can be performed. The administrator can do monitoring and management under the state of sending screens of diverse parking zones up via a monitor of the single management terminal 800.
As shown in FIG. 5C, it is preferable to make at least indications capable of identifying long-term parking vehicles marked on the management terminal 800. Thus, in case of displaying a total or part of parking zones through the management terminal 800, different colors, for example, yellow, orange and red may be used for long-term parking vehicles within target parking zones. These colors may be used on the basis of parking period of time. For example, more than 5 hours parked vehicles may be set as yellow, more than 8 hours parked vehicles as orange, and more than 12 hours parked vehicles as red. By doing so, the long-term parking vehicles can be easily distinguished from one another. By this configuration, an inconvenience task of identifying the long-term parking vehicles while the administrator looks for them one by one is no longer required.
As shown in FIG. 5D, the parking control system of the present invention photographs the parking lot inside with the plurality of cameras, thereby providing a security system with more stability.
Referring back to FIGS. 1 and 2, the parking control system of the present invention provides a monitoring service over the Internet. For this, the server unit 500, the management terminal 800 and the search terminal 900 of the present invention are connected over a network including a wire/wireless Internet and so on.
Therefore, it is possible to connect any in other places within the building to which the parking lot belongs to the same network by wire/wireless, or search parking information having parking positions of individual vehicles and/or monitor parking status through the fixed terminal 910 and/or a mobile terminal 920 connected to the same network over the Internet. For example, using the mobile communication terminal 920 can be connected to the server unit 500 over the Internet connection, thereby making it possible to monitor moving images of the parked vehicles. For monitoring, a vehicle number is inputted, as in search via the kiosk mentioned above. Then, the management program of the server unit 500 extracts the parking information of a corresponding vehicle from the database. Next, the corresponding vehicle is photographed by the inner photographing camera 302 closest to its parking position, and photographed image is sent. The parking information relating to the parking time and parking position of the vehicle may be provided together with the image. Further, when the parking information is clicked where necessary, for example, a layout in which a path for going to the parked vehicle is marked may be displayed. By this configuration, the user of the parking lot can monitor the parked vehicle at any time, and can know information about the parking times and positions of the currently parked vehicles.
In addition, the parking control system of the present invention includes a guidance structure for exit of vehicles, notifying the driver of the vehicle C getting out of the parking lot of the status of each of a plurality of centers for settlement of a parking fee and conditions of outside road. This can be accomplished by using at least one outer photographing unit 400 that photographs the road conditions outside the parking lot and a status guidance screen 620 that displays the outside road conditions photographed by the outer photographing unit 400 for the driver of the vehicle getting out of the parking lot. The status guidance screen 620 may display the status of each of the plurality of centers for settlement of the parking fee at once. An example of this status guidance screen 620 is exemplified in FIG. 6. The outer photographing unit 400 may also be constituted by an outer photographing camera 401 and a control box 402.
Preferably, the photographed contents may be stored through the inner photographing unit 300 so that the required contents can be reproduced when necessary. The contents photographed by the inner photographing unit 300 may be recorded, examples of which are contact accidents which may occur during parking or occurrence conditions such as stolen accidents. This structure leads to rapid accurate problem resolution, and also to psychological protective effect.
