Description

{METHOD, DEVICE AND SYSTEM FOR PROVIDING APPLICATION SERVICE ACCORDING TO PARKING STATUS JUDGMENT AND PARKING STATUS BASED ON VEHICLE OBJECT DETECTION}

The embodiments below relate to a technology for judging parking status and providing application services according to parking status based on vehicle object detection.

Traditionally, loop coils, ultrasonic sensors, and image-guided cameras have been used to count the number of vehicles parked in a parking lot.

The vehicle counting method using a loop coil can be composed of a loop coil, a vehicle detector, a central surveillance panel, and an entrance comprehensive information board. This method has the advantage of being able to be built at a low cost, but has the disadvantage of being unable to provide accurate information because, as the number of vehicles passing through the upper part of the loop coil is counted, not only automobiles but also motorcycles, bicycles, people wearing safety shoes, and carts are all counted.

The vehicle counting method using an ultrasonic sensor can be configured to include an ultrasonic sensor, a zone controller, an induction control PC, and an entrance comprehensive information board. This method enables accurate counting by attaching a sensor to the top of each parking space and counting, and has the advantage of ensuring user visibility by installing visualized products such as red/green, and being able to link with various visualized products such as space indicator lights, floor information boards, and block induction lights. However, there are disadvantages such as high installation costs, signal cables that must be introduced for each sensor, additional auxiliary materials for introduction/fixing, and a long construction period, which causes inconvenience in using the parking lot.

The vehicle counting method using a video-guided camera can be configured to include a video-guided camera, storage, guidance control PC, and entrance comprehensive information board. This method installs one camera per multiple parking spaces, and it is easy to find the location of my car, manage security data, and manage accidents in the parking lot through license plate recognition. It has the advantage of ensuring user visibility by installing visualized products such as red/green, and being able to be linked with various visualized products such as space indicator lights, floor information boards, and block guidance lights. However, it has the disadvantages of high installation costs, requiring signal cables for each sensor, additional auxiliary materials for introduction/fixation, and a long construction period, which causes inconvenience in using the parking lot.

In other words, the existing vehicle counting method has limitations in providing accurate information when the construction cost is low, and when accurate information can be provided, the installation cost is high, so there is a problem that there is no service that can be provided when a service such as counting the number of parking spaces at a low cost in small and medium-sized buildings to guide users and control the use of parking lots when they are full is desired.

Therefore, in order to solve the above-mentioned problem, development of a technology to efficiently improve the vehicle counting method is required.

According to one embodiment, by recognizing entry and exit through CCTV video analysis, the method of counting the number of idle spaces in small and medium-sized parking lots can be improved, thereby enabling accurate counting of data on the number of available parking spaces at a low cost.

In addition, according to one embodiment, data on the number of available parking spaces can be used to control entry when the space is full, thereby reducing complaints from users due to unnecessary movement/waiting and reducing carbon emissions due to unnecessary movement/waiting.

In addition, according to one embodiment, by displaying the location of other parking lots with available space on a display device, it is possible to prevent traffic congestion through dispersion of users, and by linking with a navigation platform, it can help increase platform value and improve driver convenience, and when determining a building traffic impact fee, it can help determine it based on clear data.

Figure 1 is a drawing schematically showing the configuration of a system according to one embodiment, and Figure 2 is a drawing showing the installation status of multiple CCTVs by floor according to one embodiment.

Referring to FIG. 1, a system according to one embodiment may include a plurality of CCTVs (100), display devices (200), and devices (300) that can communicate with each other through a communication network.

First, the communication network can be configured regardless of the communication mode, such as wired or wireless, and can be implemented in various forms to perform communication between servers and between servers and terminals.

The third CCTV (130) is installed at a point where filming is possible for the entrance to the third basement floor, so that filming can be performed for Zone 3, which is a part of the entrance road connecting the second basement floor and the third basement floor.

As shown in (b) of FIG. 2, in the case of an above-ground parking lot, the first floor is the entrance/exit of the parking lot, the second floor is the first floor, the third floor is the second floor, and the fourth floor is the third floor. The first CCTV (110) is installed at a point where filming is possible for the access road to the second floor, so that filming can be performed for Zone 1, which is a part of the access road connecting the first and second floors. The second CCTV (120) is installed at a point where filming is possible for the access road to the third floor, so that filming can be performed for Zone 2, which is a part of the access road connecting the second and third floors. The third CCTV (130) is installed at a point where filming is possible for the access road to the fourth floor, so that filming can be performed for Zone 3, which is a part of the access road connecting the third and fourth floors.

That is, the first CCTV (110) can generate first image information by performing filming for a first area, which is a part of the entrance road of the first floor, the second CCTV (120) can generate second image information by performing filming for a second area, which is a part of the entrance road of the second floor, and the third CCTV (130) can generate third image information by performing filming for a third area, which is a part of the entrance road of the third floor.

Each of the multiple CCTVs (100) can be installed on the ceiling to film in the direction of the ground when filming a certain area among the entrances to each floor, and can detect objects passing through each area.

Each of the plurality of CCTVs (100) may be composed of a combination of a motion detector camera having a function of detecting moving objects within a shooting area, an RGB camera that captures high-definition images, a camera equipped with a more reliable radar, a pan-tilt camera for performing automatic tracking, a network camera capable of performing IP communication, etc.

A plurality of CCTVs (100) can be connected to the device (300) through a network and can be operated by a control signal received from the device (300).

The display device (200) is a device installed at a specific location to display information, and may be implemented as a kiosk, signage, entrance information board, etc., but is not limited thereto, and may be implemented as various devices that are connected to an external device through communication and display information.

The display device (200) can display information such as the status of each floor of the parking lot and the number of available parking spaces on the screen.

The display device (200) can be connected to the device (300) through a network and can be operated by a control signal received from the device (300).

The device (300) may be a server owned by a person or organization providing a service using the device (300), may be a cloud server, or may be a p2p (peer-to-peer) collection of distributed nodes. The device (300) may be configured to perform all or part of the computational functions, storage/reference functions, input/output functions, and control functions of a typical computer.

The device (300) can be configured to communicate with multiple CCTVs (100) via wired or wireless communication, and can control the operation of each of the multiple CCTVs (100) to control whether to shoot, the shooting angle, the shooting direction, whether to save image information, etc.

The device (300) can be configured to communicate with the display device (200) wirelessly or wiredly, control the operation of the display device (200), and control which information to display on the screen of the display device (200).

Meanwhile, for convenience of explanation, only the first CCTV (110), the second CCTV (120), and the third CCTV (130) among the multiple CCTVs (100) are illustrated in Fig. 1, but the number of CCTVs may vary depending on the size of the parking lot. There is no particular limitation on the number of CCTVs as long as the processing capacity of the device (300) allows.

According to one embodiment, the device (300) can be connected to a cloud server to provide various services, and can provide services such as providing navigation platform information, providing valet parking platform information, providing patent/operating company application information, and utilizing a database for traffic impact assessment of a building.

The display device (200) can display additional information such as advertisements/notices in some areas and display parking lot information such as the number of available parking spaces per floor and nearby parking lots when the parking lot is full in the remaining areas.

The device (300) obtains image information from multiple CCTVs (100), and based on the obtained image information, determines the number of idle spaces in the parking lot, and can display full parking guidance information on the display device (200) when the parking lot is full, and can provide additional services such as interlocking the opening and closing of a parking barrier and guidance on available parking areas when there are empty spaces.

That is, regardless of the CCTV model, the device (300) can obtain the corresponding video as long as there is a CCTV capable of checking the parking space and analyze the full/empty situation of the parking lot, and in the case of a parking lot with a parking barrier system, the barrier can be closed when the parking lot is full and the full situation can be intuitively notified to the driver through the display device (200), and further, if there is a vehicle waiting to enter the parking lot despite the parking lot being full, the full situation can be notified again through the voice output from the display device (200), and the full/empty situation of nearby parking lots can also be collected through the cloud, and if parking is possible in a nearby parking lot, a detour guide to that parking lot can be provided, thereby preventing traffic congestion and carbon emissions caused by waiting and stopping.

FIG. 3 is a flowchart for explaining a process of determining a parking status based on vehicle object detection according to an embodiment and providing an application service according to the parking status, FIG. 4 is a diagram illustrating a process of classifying a vehicle into an entering vehicle through analysis of image information according to an embodiment, and FIG. 5 is a diagram illustrating a process of classifying a vehicle into an exiting vehicle through analysis of image information according to an embodiment.

Referring to FIG. 3, first, in step S301, if filming is being performed on a first zone, which is a part of the entrance to the first floor, through the first CCTV (110), the device (300) can obtain first image information generated by filming of the first zone from the first CCTV (110). At this time, the first CCTV (110) can perform filming of the first zone to generate the first image information in real time, and the device (300) can obtain the first image information generated by filming of the first zone in real time. Here, the first zone is a part of the entrance to the first floor, and when trying to move from the entrance of the parking lot to the first floor, one must pass through the first zone to move to the first floor, and when trying to move from the first floor to the entrance of the parking lot, one must pass through the first zone to move to the entrance of the parking lot.

In step S302, the device (300) can set a first reference line for detecting the passage of an object on the first image information. At this time, the first reference line can be set as a horizontal line passing through the center portion of the first area.

In step S303, the device (300) can monitor whether there is an object passing through the first reference line based on the first image information.

That is, the device (300) can analyze the first image information in real time to monitor whether there is an object passing through the first reference line.

In step S304, the device (300) can check whether an object passing the first baseline has been detected as a result of monitoring performed through step S303.

If it is determined that no object passing the first baseline is detected in step S304, the process can be repeated from step S303 to monitor whether there is an object passing the first baseline.

If it is confirmed that an object passing the first reference line is detected in step S304, in step S305, the device (300) recognizes the object passing the first reference line as a first object and can analyze the type of the first object based on the first image information.

That is, the device (300) monitors whether there is an object passing through the first reference line, and if it detects that the first object has passed the first reference line, it can analyze the type of the first object.

When analyzing the type of the first object, the device (300) can analyze whether the type of the first object is a vehicle or not a vehicle, and a detailed description related to this will be described later with reference to FIG. 6.

At step S306, the device (300) can determine whether the first object has been analyzed as a vehicle based on the results of analyzing the type of the first object through step S305.

If it is determined at step S306 that the first object is not analyzed as a vehicle, and as a result of analyzing the type of the first object, it is determined that the first object is not a vehicle, the process returns to step S303, and the process can be repeated from the beginning to monitor whether there is an object passing the first baseline.

If it is determined in step S306 that the first object is analyzed as a vehicle, then in step S307, the device (300) can determine the direction in which the first object entered to pass the first reference line.

That is, if the device (300) analyzes the type of the first object and determines that the first object is a vehicle, it can identify the entry direction when the first object passes the first reference line. At this time, the device (300) can identify whether the entry direction of the first object is the first direction or the second direction, and the first direction can mean the direction toward the first floor, and the second direction can mean the direction coming out of the first floor, which is opposite to the first direction.

In step S308, the device (300) can check whether the entry direction of the first object confirmed through step S307 is the first direction.

If the entry direction of the first object is confirmed in the first direction at step S308, then at step S309, the device (300) can classify the first object as an entering vehicle of the first floor.

For example, when the device (300) acquires first image information in real time from the first CCTV (110), it can extract an image of the most recently acquired image from the first image information at preset intervals, acquire the first image shown in (a) of FIG. 4 from the first image information at the first time point, acquire the second image shown in (b) of FIG. 4 from the first image information at the second time point that is after the first time point, and acquire the third image shown in (c) of FIG. 4 from the first image information at the third time point that is after the second time point.

When the device (300) acquires the first image, the second image, and the third image, respectively, the device (300) can detect that the first object (410) has entered the first zone from above based on the first image, can detect that the first object (410) has passed the first reference line (401) based on the second image, and can detect that the first object (410) has exited the first zone from below based on the third image.

That is, the device (300) can analyze the first image, the second image, and the third image in conjunction to determine that the first object (410) is moving from the upper side to the lower side, and through this, can detect that the first object (410) has passed the first reference line (401) while moving in the first direction. At this time, the device (300) can determine the entry direction of the first object in the first direction, and classify the first object as an entering vehicle on the first floor.

At step S310, the device (300) can change the number of parking spaces on the first floor by decreasing it by one.

For example, if the number of parking spaces available on the first floor is set to 10, and the device (300) classifies the first object as an entry vehicle on the first floor, it can detect that one vehicle has entered the first floor and change the number of parking spaces available on the first floor from 10 to 9.

The device (300) can control the information displayed on the display device (200) to be changed and displayed accordingly when the number of available parking spaces on the first floor decreases and changes.

After step S310, the process can be repeated by going back to step S303 and monitoring whether there is an object passing the first baseline.

If the entry direction of the first object is not confirmed in the first direction at step S308, the entry direction of the first object can be confirmed in a second direction opposite to the first direction, and if the entry direction of the first object is confirmed in the second direction, at step S311, the device (300) can classify the first object as an exiting vehicle of the first floor.

For example, when the device (300) acquires first image information in real time from the first CCTV (110), it can extract an image of the most recently acquired image from the first image information at preset intervals, acquire the fourth image shown in (a) of FIG. 5 from the first image information at the first time point, acquire the fifth image shown in (b) of FIG. 5 from the first image information at the second time point that is after the first time point, and acquire the sixth image shown in (c) of FIG. 5 from the first image information at the third time point that is after the second time point.

When the fourth image, the fifth image, and the sixth image are respectively acquired by the device (300), the device can detect that the first object (410) has entered the first zone from below based on the fourth image, can detect that the first object (410) has passed the first reference line (401) based on the fifth image, and can detect that the first object (410) has exited the first zone from above based on the sixth image.

That is, the device (300) can analyze the fourth image, the fifth image, and the sixth image in conjunction to determine that the first object (410) is moving from the bottom to the top, and through this, can detect that the first object (410) has passed the first reference line (401) while moving in the second direction. At this time, the device (300) can determine the entry direction of the first object in the second direction, and classify the first object as an exiting vehicle on the first floor.

At step S312, the device (300) can change the number of parking spaces on the first floor by increasing it by one.

For example, if the number of available parking spaces on the first floor is set to 10, and the device (300) classifies the first object as an exiting vehicle on the first floor, it can detect that one vehicle has exited the first floor and change the number of available parking spaces on the first floor from 10 to 11.

The device (300) can control the information displayed on the display device (200) to be changed and displayed accordingly when the number of available parking spaces on the first floor increases and changes.

After step S312, the process can be repeated by returning to step S303 and performing monitoring for objects passing the first baseline.

As described above, the device (300) can detect entry and exit of the first floor based on the first image information, and through this, can efficiently count the number of vehicles parked on the first floor by increasing or decreasing the number of vehicles that can be parked on the first floor.

FIG. 6 is a flowchart illustrating a process for determining whether an object passing a first reference line according to an embodiment is a vehicle or not, and FIG. 7 is a drawing illustrating a first reference line and a first line according to an embodiment.

Referring to FIG. 6, first, in step S601, the device (300) can distinguish a portion through which a first object passes from a first reference line as a first line based on first image information.

For example, when a first reference line (401) is set on the first image information as shown in (a) of FIG. 7, the device (300) acquires an image when the first object (410) passes the first reference line (401), and, based on the acquired image, as shown in (b) of FIG. 7, the portion through which the first object (410) passes through the first reference line (401) can be distinguished as the first line (402).

At step S602, the device (300) can set the length of the first line on the first image information to the first length and set the length of the first reference line to the second length.

At step S603, the device (300) can calculate a first ratio as a value obtained by dividing the first length by the second length.

At step S604, the device (300) can check whether the first ratio is higher than the reference ratio. Here, the reference ratio can be set differently depending on the embodiment.

If it is determined in step S604 that the first ratio is higher than the reference ratio, in step S605, the device (300) can analyze that the first object is a vehicle.

That is, when the device (300) determines that the ratio occupied by the first line is greater than or equal to a certain level when the first object passes the first reference line, it can analyze that the first object is a vehicle.

If it is determined in step S604 that the first ratio is not higher than the reference ratio, then in step S606, the device (300) can analyze that the first object is not a vehicle.

That is, when the device (300) determines that the ratio occupied by the first line is less than a certain level when the first object passes the first reference line, it can analyze that the first object is not a vehicle.

Figure 8 is a flowchart for explaining a process of increasing or decreasing the number of parking spaces available on a floor-by-floor basis according to an embodiment of the present invention.

Referring to FIG. 8, first, in step S801, if the first floor and the second floor are connected and the second CCTV (120) is filming a part of the second zone among the entrances to the second floor, the device (300) can obtain second image information generated by the filming of the second zone from the second CCTV (120). At this time, the second CCTV (120) can perform filming of the second zone to generate the second image information in real time, and the device (300) can obtain the second image information generated by the filming of the second zone in real time. Here, the second zone is a part of the entrances to the second floor, and when trying to move from the first floor to the second floor, one can move to the second floor only by passing through the second zone, and when trying to move from the second floor to the first floor, one can move to the first floor only by passing through the second zone.

In step S802, the device (300) can set a second reference line for detecting the passage of an object on the second image information. At this time, the second reference line can be set as a horizontal line passing through the center portion of the second area.

At step S803, the device (300) can monitor whether there is an object passing through the second reference line based on the second image information.

That is, the device (300) can analyze the second image information in real time to monitor whether there is an object passing through the second reference line.

In step S804, the device (300) can check whether an object passing the second baseline has been detected as a result of monitoring performed through step S803.

If it is determined that no object passing the second baseline is detected in step S804, the process can return to step S803 and start again from the process of monitoring whether there is an object passing the second baseline.

If it is confirmed that an object passing the second reference line is detected in step S804, then in step S805, the device (300) recognizes the object passing the second reference line as a second object and can analyze the type of the second object based on the second image information.

That is, the device (300) monitors whether there is an object passing through the second reference line, and if it detects that the second object has passed the second reference line, it can analyze the type of the second object.

When analyzing the type of the second object, the device (300) can analyze whether the type of the second object is a vehicle or not a vehicle.

At step S806, the device (300) can determine whether the second object has been analyzed as a vehicle based on the results of analyzing the type of the second object through step S805.

If it is determined at step S806 that the second object is not analyzed as a vehicle, and as a result of analyzing the type of the second object, it is determined that the second object is not a vehicle, the process returns to step S803, and the process can be repeated from the beginning to monitor whether there is an object passing the second baseline.

If it is determined in step S806 that the second object is analyzed as a vehicle, then in step S807, the device (300) can determine the direction in which the second object entered to pass the second reference line.

That is, if the device (300) analyzes the type of the second object and determines that the second object is a vehicle, it can confirm the entry direction when the second object passes the second reference line.

In step S808, the device (300) can check whether the entry direction of the second object confirmed through step S807 is the first direction.

If the entry direction of the second object is confirmed in the first direction at step S808, then at step S809, the device (300) can classify the second object as an entering vehicle of the second floor.

At step S810, the device (300) can change the number of parking spaces on the second floor by decreasing it by one, and can change the number of parking spaces on the first floor by increasing it by one.

For example, if the number of parking spaces available on the first floor is set to 10 and the number of parking spaces available on the second floor is set to 15, when the device (300) classifies the second object as an entry vehicle on the second floor, it can detect that one vehicle has entered the second floor from the first floor, and change the number of parking spaces available on the second floor from 15 to 14 and change the number of parking spaces available on the first floor from 10 to 11.

The device (300) can control the information displayed on the display device (200) to be changed and displayed accordingly when the number of available parking spaces on the first floor increases and changes and the number of available parking spaces on the second floor decreases.

After step S810, the process can be repeated by returning to step S803 and performing monitoring for objects passing the second baseline.

If the entry direction of the second object is not confirmed in the first direction at step S808, the entry direction of the second object can be confirmed in the second direction opposite to the first direction, and if the entry direction of the second object is confirmed in the second direction, at step S811, the device (300) can classify the second object as an exiting vehicle of the second floor.

At step S812, the device (300) can change the number of parking spaces on the second floor by increasing it by one, and can change the number of parking spaces on the first floor by decreasing it by one.

For example, if the number of parking spaces available on the first floor is set to 10 and the number of parking spaces available on the second floor is set to 15, when the device (300) classifies the second object as an exiting vehicle on the second floor, it detects that one vehicle has exited from the second floor to the first floor, and changes the number of parking spaces available on the second floor from 15 to 16 and changes the number of parking spaces available on the first floor from 10 to 9.

The device (300) can control the information displayed on the display device (200) to be changed and displayed accordingly when the number of available parking spaces on the first floor decreases and changes and the number of available parking spaces on the second floor increases.

After step S812, the process can be repeated by returning to step S803 and performing monitoring for objects passing the second baseline.

As described above, the device (300) can detect entry and exit of the second floor based on the second image information, and through this, by increasing and decreasing the number of parkable vehicles on the second floor and the number of parkable vehicles on the first floor in a linked manner, the number of vehicles parked on each floor can be efficiently counted.

Figure 9 is a flowchart for explaining a process of displaying the number of available parking spaces on each floor according to an embodiment.

Referring to FIG. 9, first, in step S901, if the parking lot is divided into multiple floors, the device (300) can check the number of available parking spaces for each of the multiple floors.

For example, if a parking lot is divided into the first floor, the second floor, and the third floor, the device (300) can check the number of available parking spaces on the first floor, the number of available parking spaces on the second floor, and the number of available parking spaces on the third floor, respectively. At this time, the number of available parking spaces on each floor can be updated in real time as a value increased or decreased by detecting entry and exit of each floor.

In step S902, the device (300) can control the number of available parking spaces for each of multiple floors to be displayed on the screen of the display device (200). At this time, the display device (200) is a device installed in a parking lot, and can be implemented as a kiosk, signage, entrance comprehensive information board, etc.

For example, if a parking lot is divided into a first floor, a second floor, and a third floor, the device (300) can control the number of available parking spaces on the first floor, the number of available parking spaces on the second floor, and the number of available parking spaces on the third floor to be displayed on the screen of the display device (200).

That is, the device (300) can control the number of available parking spaces on each floor to be displayed on the screen of the display device (200) for each floor.

When the device (300) controls the number of available parking spaces for each of multiple floors to be displayed on the screen of the display device (200), the number of available parking spaces for each floor can be controlled to be displayed in different colors according to the size of the number of available parking spaces. A detailed description related to this will be described later with reference to FIG. 10.

Figure 10 is a flowchart for explaining a process of displaying the number of available parking spaces on each floor in different colors according to an embodiment.

Referring to FIG. 10, first, in step S1001, the device (300) may set a floor among a plurality of floors in which the number of available parking spaces is confirmed to be greater than a first reference number of spaces to an available state, set a floor among a plurality of floors in which the number of available parking spaces is confirmed to be less than the first reference number of spaces but greater than the second reference number of spaces to an ordinary state, set a floor among a plurality of floors in which the number of available parking spaces is confirmed to be less than the second reference number of spaces but greater than 0 to an overflow state, and set a floor among a plurality of floors in which the number of available parking spaces is confirmed to be 0 to an overflow state. Here, the first reference number of spaces may be set differently depending on the embodiment, and the second reference number of spaces may be set to a lower value than the first reference number of spaces.

For example, if the first standard number of parking spaces is set to 20 and the second standard number of parking spaces is set to 10, the device (300) can set the first floor to a free state if the number of available parking spaces on the first floor is confirmed to be 25, set the first floor to a normal state if the number of available parking spaces on the first floor is confirmed to be 15, set the first floor to a crowded state if the number of available parking spaces on the first floor is confirmed to be 5, and set the first floor to a full state if the number of available parking spaces on the first floor is confirmed to be 0.

In step S1002, the device (300) can control the number of available parking spaces on a floor set to an available state on the screen of the display device (200) to be displayed in a first color, control the number of available parking spaces on a floor set to an ordinary state on the screen of the display device (200) to be displayed in a second color, control the number of available parking spaces on a floor set to an empty state on the screen of the display device (200) to be displayed in a third color, and control the number of available parking spaces on a floor set to an full state on the screen of the display device (200) to be displayed in a fourth color.

When the device (300) controls the number of available parking spaces on a floor set to a free state to be displayed in a first color, it can control the display to be displayed in a first color of different saturation in consideration of the parking status of each floor, and a detailed description related thereto will be described later with reference to FIG. 11.

Figure 11 is a flowchart for explaining a process of displaying the parking status of each floor with a first color of different saturation according to an embodiment.

Referring to FIG. 11, first, in step S1101, the device (300) can confirm that the first layer is set to a free state.

At step S1102, if it is confirmed that the first layer is set to a free state, the device (300) can check the state of each layer except for the first layer among the multiple layers.

At step S1103, the device (300) can classify the layers set to a free state among the remaining layers into the first group.

At step S1104, the device (300) can check whether there is a layer classified into the first group.

If it is confirmed that there is no layer classified into the first group in step S1104, in step S1105, the device (300) can set the saturation grade of the first layer to the highest grade. At this time, the higher the saturation grade, the more vivid the color can be displayed, and in the case of the highest grade, the most vivid color can be displayed.

If it is confirmed in step S1104 that there is a floor classified as the first group, in step S1106, the device (300) can compare the number of available parking spaces of the first floor with the number of available parking spaces of each floor classified as the first group to determine the ranking of the first floor.

For example, if the second floor and the third floor are classified into the first group, the device (300) can determine that the number of available parking spaces on the first floor is 20, the number of available parking spaces on the second floor is 15, and the number of available parking spaces on the third floor is 30 by comparing the number of available parking spaces on each floor and determine the ranking of the first floor as 2nd.

At step S1107, the device (300) can set the saturation grade of the first layer to a higher grade as the rank of the first layer is higher.

For example, if the rank of the first layer is determined as rank 2, the device (300) can set the saturation grade of the first layer to rank 1, and if the rank of the first layer is determined as rank 1, the saturation grade of the first layer can be set to rank 2. At this time, the saturation grade can be displayed more clearly when it is rank 2 than when it is rank 1.

When the saturation grade of the first layer is set through step S1105 or step S1107, in step S1108, the device (300) can control the number of available parking spaces of the first layer to be displayed on the screen of the display device (200) in the first color set to the saturation grade of the first layer.

That is, when the first layer is set to a free state, the device (300) can check the state of each of the remaining layers and control the first layer to be displayed in a clearer first color as there are no layers set to a free state among the remaining layers.
