As shown in FIG. 1, the cameras (C1 to C11) and the display boards (D1 to D7) applied to the present invention are used to photograph vehicles entering the entrance (IN) of the parking lot, track them, and guide them to the location of the vacant parking booth. As such, in the present invention, for convenience of description, the form of parking areas 100 and 200 having 10 parking booths A1 to A10 (B1 to B10) is shown, but in the case of a large parking lot, a plurality of parking booths are provided. A parking area of may be provided.

A first camera (C1) that photographs the entrance (IN) side for tracking vehicles entering the parking lot through the entrance (IN), and a first camera (C1) installed to photograph the location where the driving path is changed between the parking areas (100, 200). The second camera (C2), the fourth camera (C4), the tenth camera (C10), the first camera (C11), a third camera (C3) installed at a location for photographing the driving path between the parking areas (100,200), and A fifth camera (C5), a sixth camera (C6), a seventh camera (C7), and an eighth camera (C8) are positioned to take a picture of a plurality of parking booths forming the parking area (100, 200) on one screen. ), a ninth camera C9 is installed.

In addition, the electronic signboards (D1 to D7) for guiding the tracking vehicle to the location of the specific parking booth (A9), which is an empty parking booth for the disabled, are first camera (C1), second camera (C2), third camera (C3) ), the fourth camera (C4), the fifth camera (C5), the tenth camera (C10), and the eleventh camera (C11) are installed so that the driver can face them when driving the vehicle.

In addition, it is preferable that each of the cameras C1 to C11 and the display boards D1 to D7 be installed outside or above the driving path of the parking lot so as not to be directly damaged by a vehicle.

As shown in FIG. 2, the electric display boards D1 to D7 display the recognized vehicle number and the direction to the parking booth, and are preferably installed on the upper part of the driving path so that the driver can easily recognize them.

Of course, the specific parking booth A9 may be a parking booth for a compact car or truck, as well as a parking booth for disabled vehicles.

In addition, as shown in FIG. 3, when the preceding vehicle passes the position of the electric signboard D, the following vehicle is photographed by the camera C, and the vehicle number and driving direction of the following vehicle are displayed based on the recognized information. do.

The present invention configured as described above will be described.

First, the images of the parking booths (A1 to A10) (B1 to B10) photographed from the sixth camera (C6) to the ninth camera (C9) are received by the image processing unit 300 and processed to facilitate image recognition, Image data suitable for image recognition is generated through processing such as removing noise included in the image or converting an analog signal into a digital signal.

The captured images of the parking booths (A1 to A10) (B1 to B10) output from the image processing unit 300 are input to the parking booth recognition unit 450 of the image recognition unit 400 and deep-learned so that the current vehicle is not parked. and recognize an empty parking booth.

At this time, an artificial intelligence algorithm is built in the parking booth recognition unit 450 to recognize a state in which a vehicle is parked in a parking booth and a state in which a vehicle is not parked, and recognition information for an empty parking booth is obtained through deep learning. is provided to the controller 500.

In addition, from the parking booth images taken by the sixth camera (C6), the seventh camera (C7), the eighth camera (C8), and the ninth camera (C9), the parking booth recognition unit 450 is assigned to each parking booth. A unique number is assigned to, as in Figure 1, the unique numbers (A1 to A10) (B1 to B10) assigned to each parking booth being photographed are stored, or the unique number displayed on the floor of the parking booth is recognized. and may be stored.

Accordingly, the controller 500 receives information on the currently empty parking booth, that is, a unique number, and provides it to the storage unit 600, and this process is performed periodically (eg, 5 to 10 seconds) so that the storage unit ( 600) to update the parking booth information.

In particular, the storage unit 600 includes information on a specific parking booth allocated for parking of special vehicles such as compact cars, vehicles for the disabled, and trucks, and information on parking booths of general vehicles adjacent to or adjacent to the specific parking booth. will be storing

Thereafter, when a vehicle enters through the entrance IN, the first camera C1 photographs it, and the captured image is processed in the image processing unit 300 and then the license plate recognition unit of the recognition unit 400. 410, the vehicle type recognizing unit 420, and the vehicle tracking unit 430.

The vehicle number recognition unit 410 is for recognizing the vehicle number from the photographed vehicle image by deep learning, and such vehicle number recognition technology can use a known technology. As an example, Patent Registration No. 10-1496390 (Vehicle Number Recognition System) and Registered Patent No. 10-281861 (Vehicle License Plate Detection and Recognition System and Method).

In addition, the image processed by the image processing unit 300 is input to the vehicle type recognition unit 420, and the type of vehicle is recognized by deep learning. The shape and size of the vehicle are recognized. It may be a van, a truck, a vehicle for the disabled, etc., and the size may be a large car, a medium car, a small car, or a compact car.

In particular, in the case of a vehicle for a disabled person, it is possible to determine whether the vehicle is a vehicle for a disabled person by recognizing a parking permit for a disabled person exposed through a front window of the vehicle, that is, a windshield.

The technology for recognizing such a vehicle type can also use a known technology, as an example, Patent Registration No. 10-1996101 (Intelligent compact vehicle identification system and standalone-based intelligent license plate recognition system employing the same), registered Technologies such as Patent No. 10-1321597 (image interpretation based vehicle recognition and unmanned settlement system) can be used.

In addition, the vehicle is tracked by the vehicle information captured by the respective cameras C1 to C9 and recognized by the vehicle number recognition unit 410 and the vehicle type recognition unit 420. As shown in FIG. 6, the vehicle number The vehicle information is recognized by the current image frame of the vehicle recognized by the recognition unit 410 and the vehicle type recognition unit 420, and the vehicle information of the current image frame and the previous image frame are compared with the previous image frame of the vehicle. Intersection Over Union (IOU) is calculated from the vehicle information of the vehicle.

IOU is used as a metric value in the cup computer vision field. It is a technology that provides a normalized value regardless of the height and width of the tracking target, and is a technology widely used in the tracking field.

Therefore, the coordinate median value is calculated from the vehicle information of the current image frame and the previous image frame, respectively, and the IOU is calculated by the calculated median coordinate value. Then, if the IOU is greater than 0, the distance traveled is calculated based on this difference value. .

Accordingly, when the moving distance is greater than the set value, the rotation angle of the vehicle is calculated.

The rotation angle of the vehicle is for tracking the vehicle's direction change and movement on the driving path in the parking lot. If the angle is greater than the set value, the histogram of the current video frame and the previous video frame are compared to determine whether they match. .

That is, if the angle, that is, the driving direction is greater than the set value, it is determined that it is rotating on the driving path, and the direction change state of the vehicle being tracked is recognized by calculating the degree of coincidence from the histogram of the current video frame and the previous video frame. .

Therefore, when the same vehicle under tracking rotates, the state in which the vehicle changes direction in the direction of rotation is continuously tracked by the change of the histogram, and if the histogram coincidence is greater than the set value, the corresponding vehicle has changed direction. It is determined that it is, and tracking information for the driving and direction change is provided to the controller 500.

The technology of tracking the vehicle by the vehicle tracking unit 430 may use the technology of the present invention mentioned above or a known technology.

Therefore, the controller 500 is photographed and recognized by the first camera C1 in order to guide special vehicles such as light vehicles, vehicles for the disabled, and trucks entering the entrance IN to a specific empty parking booth A9. Recognition information about the vehicle number, shape, size, and handicap is received from the recognition unit 400 and the vehicle number and direction are displayed through the first electric signboard D1.

That is, the control is performed so that the information on the vehicle number and going straight is displayed on the first electronic display board (D1).

Thereafter, the second camera C2 takes a picture of the vehicle entering the entrance IN and going straight, and is recognized by the recognition unit 400, and the controller 500 accordingly displays the vehicle through the second display board D2. It is controlled to display the number and left turn, and it is tracked whether the corresponding vehicle has turned left by the information photographed and recognized by the second camera C2 and the third camera C3.

When the vehicle turns left and enters between the parking areas 100 and 200, the vehicle is tracked from the images captured by the third camera C3 and the sixth camera C6, and the vehicle enters a specific parking booth A9. When it is recognized that it is approaching, the controller 500 guides the correct parking booth by displaying that it has arrived at the specific parking booth A9 through the third display board D3 along with the license plate number.

If the vehicle continues to pass the specific parking booth (A9) and changes direction, it can recognize the vehicle again and guide it to the same parking booth or other nearby specific parking booths through the electric signboard. This algorithm Optimum parking booth guidance can be achieved by continuously performing the above-mentioned process.

In the end, if the recognized result is a van or a truck, it is guided to the location of a wide parking booth, and if it is a compact car or a vehicle for the disabled, it is guided to a dedicated parking booth. , The controller 500 controls the display of the electric signboards D1 to D5 so that guidance is made by the information recognized from the parking booth recognition unit 450 whether the corresponding parking booth is empty.

However, when the specific parking booths for guiding and parking the recognized special vehicle are not empty, the controller 500 receives the parking booth information for adjacent general vehicles stored in the storage unit 600, and then the parking booth recognition unit 450 Recognition results for specific parking booths among the empty parking booths for general vehicles recognized by the are input.

Accordingly, according to the recognition result, when special vehicles such as compact cars, vehicles for the disabled, and trucks enter the parking lot, they are guided from specific parking booths to adjacent empty parking booths for general vehicles through the display unit (D). will be.

Of course, if the vehicle is parked from a specific parking booth by the parking booth recognition unit 450 while guiding to a parking booth for a general vehicle, the controller 500 directly directs the empty specific parking booth through the display unit (D).

For example, since information on the parking booths A8, B3, and A4 adjacent to the parking booth A9 for disabled vehicles is stored in the storage unit 600, the controller 500 controls the parking booth adjacent thereto. After confirming the image recognition result for whether the parking booth is empty through the recognition unit 450, it is possible to guide the parking booth to the corresponding parking booth when it is empty.

In addition, when it is recognized that the adjacent general vehicle parking booths A8, B3, and A4 are not empty by the parking booth recognition unit 450, another parking booth adjacent to the parking booths A8, B3, and A4 is vacant. The state is confirmed by the controller 500 and guided to an empty parking booth.

As a result, it is possible to guide a special vehicle from a specific parking booth to an adjacent empty parking booth, and if a specific parking booth becomes empty during guidance, it is possible to guide the vehicle directly to the empty parking booth. A procedure for sequentially checking the empty state of adjacent parking booths is stored.

In addition, each camera (C) recognizes the following vehicle and displays the vehicle number and direction when the corresponding vehicle passes the electric signboard (D) as shown in FIG. It is to control the electronic display board (D).

In addition, when the parking booth recognizing unit 450 recognizes that a vehicle is parked in the parking booth A9 based on the image captured by the sixth camera C6, the adjacent vehicle recognizing unit 440 detects a neighboring vehicle. The information of, that is, the vehicle number is recognized and provided to the controller 500, and the controller 500 stores it in the storage unit 600.

This is to check if a contact accident occurs by a vehicle parked in a neighboring parking booth (A8, 10), and if a driver requests information on a neighboring vehicle through his or her smartphone, it is provided. To this end, in the storage unit 600, the driver's smartphone information (for example, phone number) is matched with the vehicle number to form a database.

That is, if the vehicle driver who frequently uses the parking lot registers the vehicle number and phone number in advance and stores them in the storage unit 600, when the vehicle is parked in the parking booth, the driver is detected by the nearby vehicle recognition unit 440. It recognizes the number of a neighboring vehicle together with its own vehicle number and stores it in the storage unit 600, and the communication unit 700 receives a request for data provision through the driver's smartphone.

Therefore, the controller 500 checks the vehicle number matched with the driver's phone number stored in the storage unit 600, and then provides the neighboring vehicle number to the driver's smart phone through the communication unit 700.

As a result, when a phone number is input from the driver's smart phone, the controller 500 provides information on the parking booth number and parking location along with neighboring vehicle information to the driver's smart phone through the communication unit 700.

In the above, the smartphone information phone number has been described as an example, but when a parking lot app is installed on a smartphone, information such as an ID may be used.

On the other hand, vehicle information display units (ND) in the form of electric signs are installed on the upper portions of each parking booth (A1 to A10) (B1 to B10), respectively. is displayed, which allows the driver to immediately check the location of his or her vehicle through the vehicle information display unit (ND) in a large parking lot.

That is, in a parking lot, it is very difficult to check your vehicle from a distance because the license plate number is covered by parked vehicles, but the vehicle information display unit (ND) installed above the parking booths (A1 to A10) (B1 to B10) You can easily check the location of your vehicle through

To this end, when the vehicle is parked in the corresponding parking booth (A9) by the parking booth recognition unit 450, the controller 500 receives the vehicle number recognized by the vehicle number recognition unit 410 and the vehicle tracking unit 430. It is displayed through the corresponding vehicle information display unit (ND).

In other words, when it is recognized that the vehicle is parked in the parking booth A9 by the sixth camera C6 and the parking booth recognition unit 550, the controller 500 displays the vehicle information display unit ND of the corresponding parking booth. It will display the number of the parked vehicle.

At this time, since the unique numbers of the parking booths A6 to A10 photographed by the sixth camera C6 are already set and stored in the storage unit 600, it is assumed that the tracted vehicle is parked in a specific booth A9. When recognized, the controller 500 displays the number of the recognized vehicle through the vehicle information display unit ND installed in the corresponding parking booth A9.

In addition, it is possible to change the information displayed on the vehicle information display unit (ND) through the driver's smartphone. As mentioned above, the storage unit 600 matches the phone number, vehicle number, and unique number of the parked parking booth. Therefore, display phrases such as company name, driver name, phrases or symbols to inform the driver themselves are received from the driver's smartphone through the communication unit 700, and then the driver's phone number and driver's phone number stored in the storage unit 600 The matched vehicle number is checked, the parking booth where the vehicle is parked is checked, and the information input from the driver's smartphone is displayed through the vehicle information display unit (ND) installed in the corresponding parking booth.

That is, when the display phrase is transmitted from the driver's smartphone, the controller 500 displays the display phrase through the vehicle information display unit (ND) of the parking booth where the driver's vehicle is parked, so that the driver can more intuitively control his/her vehicle. that can be seen from afar.

Each of the above parking booths (A1 to A10 (B1 to B10) is provided with a stopper protruding from the parking lot floor to prevent the vehicle being parked from colliding with a wall or a rear vehicle. When it does, the rear wheel is caught and it is no longer possible to reverse, thereby preventing a collision.

By the way, since these stoppers are fixed in a form protruding from the parking lot floor, the risk of a safety accident increases as a pedestrian trips over the stopper while passing a parking booth where the vehicle is empty.

That is, it occurs when a pedestrian is unable to check the stopper protruding from the floor of the parking lot when searching for his or her vehicle or moving toward the entrance, resulting in injuries such as bruises and fractures due to tripping.

Therefore, in the present invention, by artificial intelligence image recognition that a vehicle is parked in an empty parking booth, the stopper rises and protrudes from the parking lot floor, and when the vehicle leaves the parking booth, the stopper is lowered to level with the parking lot floor This is to prevent tripping and falling accidents by pedestrians.

To this end, as shown in FIG. 7, an installation groove 900 is formed on the floor of the parking lot where the stopper 1000 is installed, and an electric cylinder One side of the drive unit 800 in the form is coupled by a first hinge 910, and the first hinge 910 may be installed on a rear wall or bottom of the installation groove 900.

In addition, the second hinge 930 is provided at the upper part of the other side of the installation groove 900, that is, the upper part of the position facing the front side of the parking booth, so that one side part 930 of the stopper 1000, that is, the front side of the parking booth It is installed so that it can rotate in the up and down direction by being coupled to the part facing the , and the third hinge 1100 is provided on the bottom part of the stopper 1000, so that the rod 810 of the driving part 800 is rotatably coupled .

The stopper 1000 is formed to have the same area and shape as the upper end of the installation groove 900, and a seating jaw 920 protruding inward is formed on the upper side of the wall surface of the rear portion of the installation groove 900.

Therefore, when the rod 810 of the driving unit 800 is extended, the driving unit 800 rotates upward with the first hinge 910 as an axis, and thus the stopper 1000 also rotates the second hinge 930. As the shaft is lifted and erected, the movement of the parked vehicle is limited.

At this time, when the stopper 1000 moves up and down, the height of the upper end has the same height as that of the upper end of a general stopper.

In addition, when the rod 810 of the driving unit 800 is compressed, as shown in FIG. 8, the driving unit 800 rotates downward with the first hinge 910 as an axis and is accommodated in the installation groove 900, thereby The stopper 1000 also descends with the second hinge 930 as an axis and is laid down to maintain a flat state with the floor of the parking lot.

At this time, the stopper 1000 becomes a seating jaw 9200 to maintain a flat state without shaking in the vertical direction, and the height from the upper end of the seating jaw 9220 to the floor of the parking lot is the thickness of the stopper 1000 and By being formed in the same way, when the stopper 1000 descends and covers the upper portion of the installation groove 900, the bottom surface of the parking lot and the stopper 1000 are maintained in a flat state.

Due to this, in a state in which the vehicle is not parked in the parking booth, the stopper 1000 is prevented from protruding, so that walking is not hindered.

In order to raise and lower the stopper 1000, the controller 500 guides the vehicle to an empty parking booth and then drives the driving unit 800 installed in the corresponding parking booth to forward rotation to raise and lower the stopper 1000.

At this time, the parking booth recognition unit 450 recognizes that a vehicle enters the corresponding parking booth by artificial intelligence, receives the recognition result from the controller 500, and controls the driving unit 800. The stopper 1000 is moved up and down.

Conversely, if the movement of the vehicle parked in the parking booth is determined by the parking booth recognizing unit 450, since the vehicle is departing from the parking booth and exiting the vehicle, the controller 500 reversely rotates the driving unit 800 accordingly. to control the stopper 1000 to descend.

As a result, the stopper 1000 is automatically raised and lowered only when the vehicle is parked in the parking booth, and when the vehicle moves from the parking booth, the stopper 1000 is lowered to prevent pedestrians by the stopper 1000 protruding from the parking lot floor. It will prevent accidents.
