FIG.

<Configuration of the parking assistance system according to one embodiment>
The configuration of a parking assistance system according to an embodiment of the present invention will be described with reference to Fig. 1. The parking assistance system 1 according to this embodiment is installed in a self-propelled parking lot X having a plurality of parking spaces S1 to Sn. The self-propelled parking lot X is a parking lot constructed so that users pay a usage fee each time they use the parking lot.

The parking assistance system 1 comprises a plurality of camera devices 10-1 to 10-n and display devices 20-1 to 20-n installed for each parking space, and a parking assistance device 30. The outer frames of each parking space S1 to Sn are indicated by frame lines L1 to Ln on the floor of the self-propelled parking lot X, respectively.

Hereinafter, when there is no need to specify which of the parking spaces S1 to Sn it is, it will be referred to as parking space S. Similarly, the camera devices 10-1 to 10-n will be referred to as camera device 10, the display devices 20-1 to 20-n will be referred to as display device 20, and the frame lines L1 to Ln will be referred to as frame lines L.

As shown in FIG. 2, in each parking space S, the camera device 10 is installed in a position that captures the corresponding parking space S from above. The display device 20 is installed in a forward position that is easily visible from the driver's seat of a vehicle parked in the parking space S.

The camera devices 10-1 to 10-n each capture an image of the corresponding parking space from above. The display devices 20-1 to 20-n each consist of a monitor screen, and display information generated by the parking assistance device 30, which will be described later.

The parking assistance device 30 has a parking evaluation score calculation unit 31, a discount information storage unit 32, a display information generation unit 33, and a display control unit 34.

The parking evaluation score calculation unit 31 calculates a parking evaluation score based on the image information captured by the camera devices 10-1 to 10-n, with the parking evaluation score being a higher value the closer the position of the vehicle parked in each parking space S1 to Sn is to the center of the corresponding parking space. The discount information storage unit 32 stores discount information on the usage fee for the self-propelled parking lot X according to the parking evaluation score. This discount information is set, for example, so that the higher the parking evaluation score, the higher the discount rate.

The display information generation unit 33 generates display information including the parking evaluation score calculated by the parking evaluation score calculation unit 31. At that time, if the parking evaluation score is equal to or greater than a predetermined value, the display information is generated including discount information on the usage fee for the self-propelled parking lot X. The display control unit 34 causes the display information generated by the display information generation unit 33 to be displayed on the corresponding display device 20-1 to 20-n.

<Operation of the parking assistance system according to one embodiment>
The operation of the parking assistance system according to this embodiment will be described with reference to the flowchart in Fig. 3. In this embodiment, the image information captured by the camera devices 10-1 to 10-n of each of the parking spaces S1 to Sn is sequentially transmitted to the parking assistance device 30.

In the parking assistance device 30, the imaging information transmitted from the camera devices 10-1 to 10-n is acquired by the parking evaluation score calculation unit 31, and based on the acquired imaging information, it is monitored whether or not a vehicle has been parked in the corresponding parking space S. When it is detected that a vehicle Y has been parked in the corresponding parking space S ("YES" in S1), the parking evaluation score of the corresponding vehicle Y is calculated (S2). The calculation of the parking evaluation score will be explained below with three examples.

[Parking evaluation score calculation example (1)]
In the parking evaluation score calculation example (1), as shown in FIG. 4(a), the closer the center position A of the parked vehicle Y is to the center position B of the parking space S, the higher the parking evaluation score is calculated.

[Parking evaluation score calculation example (2)]
In parking evaluation score calculation example (2), as shown in FIG. 4(b), the closer the longitudinal center line C of the parked vehicle Y is to the longitudinal center line of the parking space S, the higher the parking evaluation score is calculated.

[Parking evaluation score calculation example (3)]
In parking evaluation score calculation example (3), as shown in Figure 4 (c), the closer the line E in the longitudinal direction of the parked vehicle Y and the line F in the longitudinal direction of the parking space S are to being parallel, the higher the parking evaluation score is calculated.

When calculating the parking evaluation score using the parking evaluation score calculation unit 31, any one of the above examples may be used, or two or more of them may be used in combination.

Next, the display information generating unit 33 determines whether the calculated parking evaluation score is equal to or greater than a preset value (e.g., 80 points or more out of a maximum of 100 points). If the parking evaluation score is equal to or greater than the preset value ("YES" in S3), discount information on the usage fee for the self-propelled parking lot X is obtained from the discount information storage unit 32 (S4).

Then, display information including the parking evaluation score calculated in step S2, the discount information acquired in step S4, and the image information captured by the corresponding camera device 10 is generated by the display information generating unit 33 (S5). At this time, the display information of the discount information is generated as two-dimensional barcode information.

The generated display information is displayed on the corresponding display device 20 under the control of the display control unit 34. An example of a screen layout diagram displayed on the display device 20 is shown in FIG. 5. In the screen layout diagram shown in FIG. 5, the parking evaluation score "93 points", two-dimensional barcode information G of discount information generated based on this, and image information H of the camera device 10 are displayed.

The user of vehicle Y can receive the discount service by visually checking the information displayed on display device 20, reading the two-dimensional barcode of the displayed discount information with a mobile terminal, and presenting the read information when paying for the parking fee at self-propelled parking lot X.

If the parking evaluation score is lower than the predetermined value in step S3 ("NO" in S3), the discount information is not acquired, and display information including the parking evaluation score and the image information is generated and displayed (S5).

According to the above embodiment, when a vehicle is parked in a parking space in a self-driving parking lot, a parking display score that evaluates the appropriateness of the parking position is displayed, thereby making the user conscious of parking in an appropriate location. In addition, if the parking position is highly appropriate and the parking display score is equal to or greater than a predetermined value, the user can receive a discount service for the parking lot, thereby further increasing the user's consciousness of parking in an appropriate location.

When the parking evaluation score calculation unit 31 calculates the parking evaluation score, the time from when the vehicle Y starts entering the parking space S until it is parked may be measured based on the image information captured by the camera device 10, and the shorter the measured time, the higher the calculated parking evaluation score may be. By calculating the parking evaluation score in this manner, users can be encouraged to park as quickly as possible, and congestion in the parking lot can be reduced.

In the above embodiment, a case has been described in which the surveillance camera 10 and the display device 20 are installed in all parking spaces within the self-propelled parking lot X. However, this is not limited to this, and these devices may be installed only in parking spaces that are used less frequently, such as parking spaces far from the entrance, and a discount service of the usage fee according to the parking display points may be provided only to users who use those parking spaces.

By configuring it in this way, it is possible to encourage users to actively use parking spaces that are normally used infrequently, thereby improving the utilization efficiency of the self-propelled parking lot X.
