Embodiments of a parking lot management system, a parking lot management method, a program, and a non-temporary tangible recording medium for recording the program according to the present disclosure will be described in detail below with reference to the drawings. This embodiment does not limit the disclosed technology.

(Embodiment 1)
First, in Embodiment 1, basic functions of a parking lot management system will be explained. FIG. 1 is a block diagram showing an example of a configuration of a parking lot management system according to a first embodiment. The parking lot management system 10 includes an acquisition section 101 , a vehicle detection section 102 , an imaging control section 103 , an owner detection section 104 , and an output control section 105 .

The acquisition unit 101 acquires an image of a parking frame captured by an imaging device. Obtaining here refers to obtaining images in the parking lot management system 10 in order to analyze vehicles parked for a long time, owners of the vehicles, and the like. The parking slot is, for example, a parking slot in a parking lot where customers using the facility can park their vehicles. Parking slots are individual areas in a parking lot where vehicles are parked. The facility is, for example, a store, although it is not particularly limited. The type of vehicle is not particularly limited, such as a car, bicycle, or motorcycle.

Specifically, as a method for acquiring an image, for example, the acquisition unit 101 acquires an image from a storage means. The storage means may be, for example, a database that stores captured images. Or, specifically, as another method of acquiring an image, for example, the storage section stores the captured image in the storage means. Alternatively, for example, the acquisition unit 101 may acquire an image from an imaging device. Note that, for example, the acquisition unit 101 sequentially acquires new images.

Next, the vehicle detection unit 102 detects a vehicle that has been parked in the parking slot for a predetermined period of time or more based on the images at each first time interval.

As a method for detecting a vehicle that has been parked for a long time, for example, the vehicle detection unit 102 detects a vehicle from an acquired image. Then, for example, the vehicle detection unit 102 detects stagnation and disappearance of the detected vehicle by comparing the differences between the plurality of images at each first time interval. Note that a more detailed example in which a vehicle parked for a long time is detected from an image will be described using Embodiment 2.

Here, the first time interval is, for example, a predetermined interval. The predetermined time is, for example, a predetermined time. Note that the predetermined time may be settable by an employee of the facility, a supervisor, or the like. For example, the first time interval is shorter than the predetermined time. For example, the predetermined time is one hour and the first time interval is five minutes. For example, when the vehicle detection unit 102 compares images at long time intervals such as a predetermined time, differences may occur even for the same vehicle due to the influence of sunlight. Therefore, for example, the first time interval may be set to a time at which there is a low possibility that a difference will occur between images. Then, the vehicle detection unit 102 sequentially compares the images for each first time interval.

Next, when a vehicle is detected, the imaging control unit 103 controls at least one of the storage unit and the imaging device so that images can be acquired at each second time interval, which is shorter than the first time interval. do. Here, the first time interval is a time interval used to detect a vehicle parked for a long time, as described above. On the other hand, the second time interval is a time interval used to detect the owner of a vehicle parked for a long time. If the first time interval is too short, the processing load will be large and the capacity of the storage means will be required. Generally, people are unlikely to invest in high-performance processing equipment or large-capacity storage devices for free parking for facility use. On the other hand, the owner is expected to leave as soon as he returns to the vehicle. Therefore, when detecting the owner of a vehicle using images taken at each first time interval, it is predicted that the owner may leave during the first time interval, and the owner will be missed and notification will not be possible. . Therefore, in the parking lot management system 10, in order to detect vehicles parked for a long time, images taken at each first time interval are used as analysis targets, and when a vehicle parked for a long time is detected, Images from each second time interval are used for analysis. Then, the imaging control unit 103 controls at least one of the storage unit and the imaging device in order to realize these.

First, a case where the imaging control unit 103 controls the storage unit will be described. Here, for example, the storage section stores one frame of images at each first time interval among the images captured by the imaging device in the storage means. For example, a case will be exemplified in which the imaging device captures images at 10 FPS (Frames Per Second) from time 10:00 to time 10:15, and the first time interval is 5 minutes. For example, the storage section stores one frame of image in the storage means every five minutes. For this reason, the storage means stores, for example, an image at time 10:00, an image at time 10:05, an image at time 10:10, and an image at time 10:15.

Then, when a vehicle parked for a long time is detected, the imaging control unit 103 changes the interval at which the storage unit stores in the storage unit from the first time interval to the second time interval. The interval at which the storage unit stores captured images in the storage means is also referred to as a storage interval. This storage interval is, for example, the interval between the image capturing times of images stored in the storage means among the captured images. Note that existing techniques may be used as a specific method for changing the storage interval. For example, when the acquisition unit 101 sequentially acquires images stored in the storage means, and the first time interval is 5 minutes and the second time interval is 10 seconds, the acquisition unit 101 acquires images stored in the storage means for 5 minutes. Previously, one image was acquired every 10 seconds, but now one image is acquired every 10 seconds. Note that when controlling the storage interval by the storage unit, the imaging device may be capturing a moving image or may be capturing an image.

Also, a case will be described in which the imaging control unit 103 controls the imaging device. An example is given in which the imaging device captures one image at each first time interval. For example, the storage section stores the image transmitted from the storage means in the storage means. For example, let us take a case where the first time interval is 5 minutes and the second time interval is 10 seconds. The imaging device captures one image once every 5 minutes. When a vehicle parked for a long time is detected, the imaging control unit 103 controls the imaging device to capture images at every second time interval from the first time interval. Note that existing technology may be used as a specific method for controlling the imaging device. This causes the imaging device to capture an image once every 10 seconds. For example, when the acquisition unit 101 sequentially acquires images stored in the storage means, the acquisition unit 101 acquires one image every 5 minutes, but may acquire one image every 10 seconds. become. The acquisition unit 101 may sequentially acquire images from the imaging device. Similarly, when acquiring images sequentially from the imaging device, the acquisition unit 101 acquires one image every 10 seconds, instead of acquiring one image every 5 minutes.

Furthermore, when controlling the imaging device, for example, when the imaging device captures images at each first time interval and a vehicle that has been parked for a long time is detected, the imaging control unit 103 controls the The imaging device may be controlled so as to capture a moving image from. The acquisition unit 101 has been acquiring images sequentially from the storage means or the imaging device, but now acquires a moving image.

Furthermore, when controlling the imaging device, for example, the imaging device may transmit one image of the captured images or videos to the storage means at each first time interval. When a vehicle parked for a long time is detected, the imaging control unit 103 may control the imaging device to transmit one image to the storage means every second time interval. For example, when the acquisition unit 101 sequentially acquires images stored in the storage means, the acquisition unit 101 acquires one image at each first time interval, but one image at each second time interval. will be obtained. Alternatively, when the acquisition unit 101 sequentially acquires images from the imaging device, for example, the imaging device transmits one image of the captured images or videos to the parking lot management system 10 at each first time interval. Good too. When a vehicle parked for a long time is detected, the imaging control unit 103 may control the imaging device to transmit one image to the storage means every second time interval. As a result, for example, the acquisition unit 101 acquires one image every first time interval, but now acquires one image every second time interval.

This concludes the description of the imaging control unit 103. Next, when a vehicle parked for a long time is detected, the owner detection unit 104 detects the owner of the vehicle based on the images at each second time interval. Specifically, for example, the owner detection unit 104 detects the appearance of the owner of the vehicle by comparing a plurality of images at each second time interval.

More specifically, for example, the owner detection unit 104 may detect the person inside the vehicle as the owner from the images at each second time interval. For example, the owner detection unit 104 may detect the person in the seat of the vehicle as the owner from the images taken at each second time interval. The vehicle seat may be a vehicle driver's seat.

Alternatively, for example, the owner detection unit 104 may detect a person near the vehicle from images taken at each second time interval. For example, the owner detection unit 104 may detect a person who is putting his hand on the door of the vehicle as the owner. Alternatively, for example, a person who is trying to open the trunk of a vehicle may be detected as the owner. Alternatively, for example, a person who stays in front of the vehicle door for a certain period of time may be detected as the owner.

The output control unit 105 notifies the owner when the owner is detected. Specifically, for example, the output control unit 105 may notify the owner via an output device. The output device may be a device installed in a parking lot. The output device may be a display device, a projection device, an audio output device, a lighting device, etc., and is not particularly limited. Note that an example in which the output control unit 105 notifies the owner via the output device will be described in detail using Embodiment 2.

FIG. 2 is a flowchart showing an example of the operation of the parking lot management system 10 according to the first embodiment. The acquisition unit 101 acquires an image of a parking frame captured by an imaging device (step S101). The vehicle detection unit 102 determines whether a vehicle parked in the parking slot for a predetermined period of time or more is detected based on images at each first time interval (step S102). If no vehicle is detected (step S102: No), the acquisition unit 101 returns to step S101. Then, when a new image is acquired, in step S102, the vehicle detection unit 102 detects a vehicle that has been parked for a predetermined period of time or longer.

On the other hand, if a vehicle is detected (step S102: Yes), the imaging control unit 103 controls at least one of the storage unit and the imaging device (step S103).

The acquisition unit 101 acquires a new image (step S104). Next, the owner detection unit 104 determines whether the owner of the vehicle has been detected based on the images at each second time interval (step S105). If the owner has not been detected (step S105: No), the acquisition unit 101 returns to step S104 and acquires a new image.

If the owner is detected (step S105: Yes), the output control unit 105 notifies the owner (step S106), and the parking lot management system 10 ends the process.

Here, for example, there are cases where there is no charge for using the parking lot of a store such as a convenience store. In such cases, some owners park their vehicles in parking lots for long periods of time for purposes other than using the store. Customers using the store may not be able to park their vehicles in the parking lot and therefore do not come to the store, resulting in an opportunity loss. In addition, it may cause problems in carrying luggage into the store. For example, a store employee or a parking lot supervisor may visually check the parking lot. However, in this case, it places a burden on employees and supervisors. Furthermore, in this case, misreading may occur. Furthermore, even when an employee or a supervisor confirms images using a monitoring imaging device, the confirmation work becomes a burden on the employee.

Therefore, in the first embodiment, the parking lot management system 10 detects vehicles that have been parked for a predetermined period of time or more based on images captured at each first time interval. Here, even if the time interval between consecutive images is long, such as 5 minutes, a vehicle that has been parked for a long time can be detected. On the other hand, if the time interval between consecutive images is long, it may not be possible to image the owner. In this way, the owner who is the target of notification may be overlooked. Therefore, when a vehicle is detected, the parking lot management system 10 controls the imaging device and the storage unit so that images at each second time interval can be acquired. The system detects the owner of the vehicle and notifies the owner. This makes it possible to notify the owner more reliably. Therefore, it is possible to prevent the vehicle from being parked for a long time. Furthermore, opportunity losses caused by customers not visiting the store can be suppressed. Further, it is possible to suppress interference with carrying luggage into the store.

Also, since the notification is made at the timing when the owner is detected, the notification can be suppressed compared to the case where the notification is always made from the timing when a vehicle that has been parked for a long time is detected.

Additionally, compared to the case where employees and guards visually check the parking lot, it is possible to reduce the burden on employees and guards. In this way, it is possible to improve the efficiency of facility management.

However, the notification in Embodiment 1 may be used in combination with the case where an employee or a supervisor visually checks the parking lot. By combining in this way, it is possible to more reliably notify the owner of a vehicle that has been left unattended for a long time.

In the first embodiment, the method of controlling the storage unit so that images can be acquired at every second time interval is not particularly limited. In the first embodiment, when controlling the storage unit, the parking lot management system 10 changes the storage interval by the storage unit from the first time interval to the second time interval. This makes it possible to narrow down the images to be stored in the storage means. As mentioned above, it is unlikely that companies will invest in high-performance processing equipment or large-capacity storage devices for free parking for facility use. Therefore, it is possible to narrow down the images to be stored in the storage means. Therefore, the cost can be reduced compared to the case where moving images are constantly stored in a storage means or the like.

Furthermore, in the first embodiment, there is no particular limitation on the method of controlling the imaging device so that images can be acquired at every second time interval. For example, when controlling an imaging device, the parking lot management system 10 performs control to switch the imaging by the imaging device from an image to a video. Alternatively, for example, when controlling the imaging device, the parking lot management system 10 performs control to switch the imaging interval by the imaging device from the first time interval to the second time interval. Thereby, when storing captured images in the storage means, it is possible to narrow down the images to be stored in the storage means. Therefore, the cost can be reduced compared to the case where moving images are constantly stored in a storage means or the like.

(Embodiment 2)
Next, Embodiment 2 will be described in detail with reference to the drawings. In Embodiment 2, a more detailed example in which stagnation and disappearance of a vehicle are detected will be described. In addition, in Embodiment 2, a detailed example of notifying the owner will be described. Hereinafter, a description of contents that overlap with the above description will be omitted to the extent that the description of the second embodiment is not unclear.

FIG. 3 is an explanatory diagram showing an example of a parking lot and parking lot monitoring. For example, a parking lot is a place where vehicles of customers using a store can park. For example, a parking lot has multiple parking slots. In FIG. 3, each parking slot is represented by a black line. The parking slot is not limited to the example represented by a line as long as the area can be specified. In FIG. 3, the number of parking spaces is plural, but may be one, and is not particularly limited. In FIG. 3, the type of vehicle will be explained using a car as an example, but is not particularly limited.

Furthermore, for example, an imaging device 22 is installed in a parking lot. In FIG. 3, one imaging device 22 is installed at a position where it can image a plurality of parking spaces. The imaging device 22 then images the plurality of parking spaces. Note that a plurality of imaging devices 22 may be installed, such as one imaging device 22 arranged for each parking slot. However, the smaller the number of imaging devices 22, the more the cost burden on the facility can be reduced.

FIG. 4 is an explanatory diagram showing an example of connection between the parking lot management system and other devices. In FIG. 4, for example, a parking lot management system 20 is connected to an imaging device 22 and the like via a communication network NT. As explained in FIG. 3, the number of imaging devices 22 is not particularly limited.

For example, the parking lot management system 20 is connected to a terminal device 21 and the like via the communication network NT. In FIG. 4, the number of terminal devices 21 is not particularly limited. The type of terminal device 21 is not particularly limited, such as a smartphone, a tablet device, or a PC (Personal Computer). The terminal device 21 is, for example, an employee's terminal device 21.

Additionally, the parking lot management system 20 may be connected to other devices (not shown). Other devices include, for example, an output device such as a lighting device and a display device, which will be described later.

In FIG. 4, one communication network NT is taken as an example for ease of explanation, but the parking lot management system 20 may be connected to each device by a different communication network NT, and in particular, Not limited.

FIG. 5 is a block diagram showing a configuration example of the parking lot management system 20 according to the second embodiment. The parking lot management system 20 includes an acquisition section 201 , a vehicle detection section 202 , an imaging control section 203 , an owner detection section 204 , an output control section 205 , an identification section 206 , and a storage section 207 .

The parking lot management system 20 according to the second embodiment has a specifying section 206 and a storage section 207 added to the parking lot management system 10 according to the first embodiment. The acquisition unit 201 has the function of the acquisition unit 101 according to the first embodiment as a basic function. Vehicle detection section 202 has the function of vehicle detection section 102 according to the first embodiment as a basic function. The imaging control unit 203 has the functions of the imaging control unit 103 according to the first embodiment as a basic function. The owner detection unit 204 has the function of the owner detection unit 104 according to the first embodiment as a basic function. Output control section 205 has the function of output control section 105 according to the first embodiment as a basic function.

Additionally, the parking lot management system 20 includes a captured image DB (DataBase) 2001. The captured image DB 2001 is a storage unit that stores images and moving images captured by the imaging device 22.

Next, each functional part will be explained.

The storage unit 207 stores an image of the parking frame captured by the imaging device 22 in the captured image DB 2001. For example, the storage unit 207 may store, in the captured image DB 2001, images for each first time interval among the images of the parking slot captured by the imaging device 22. More specifically, for example, if the first time interval is 1 second and the speed is 10 FPS, the storage unit 207 stores, for example, the last 1 frame out of 10 frames captured in 1 second in the captured image DB 2001. It's okay. Alternatively, for example, the storage unit 207 may store an image of a parking frame captured by the imaging device 22 in the captured image DB 2001.

The acquisition unit 201 acquires an image of the parking frame captured by the imaging device 22. As described in Embodiment 1, for example, the acquisition unit 201 acquires images stored in the captured image DB 2001. Alternatively, for example, the acquisition unit 201 may acquire a captured image from the imaging device 22.

The vehicle detection unit 202 detects a vehicle parked in a parking slot for a predetermined period of time or more based on images captured at each first time interval. As described in Embodiment 1, for example, the vehicle detection unit 202 detects a vehicle from the acquired image. Then, for example, the vehicle detection unit 202 detects stagnation and disappearance of the detected vehicle by comparing the differences between the plurality of images for each first time interval. Here, a vehicle that has been parked for a predetermined period of time or longer is also referred to as a vehicle that has been parked for a long time.

More specifically, as a method for detecting a vehicle that has been parked for a long time, for example, the vehicle detection unit 202 detects a vehicle parked in each parking slot as an object from an image. The vehicle detection unit 202 then compares the objects detected from the images at each first time interval. For example, the vehicle detection unit 202 may compare whether there is an object of the same color and the same shape for the same parking frame. For example, the vehicle detection unit 202 may compare the object detected from the image at time 12:00 with the object detected from the image at time 12:05. Furthermore, when a new image at the time of 12:10 is acquired, the vehicle detection unit 202 detects a vehicle parked in each parking slot as an object from the image. The vehicle detection unit 202 then compares the object detected from the image at time 12:05 with the object detected from the image at time 12:10. The vehicle detection unit 202 repeatedly performs such a comparison to detect a vehicle that has been parked for a predetermined period of time or longer.

As another method for detecting vehicles parked for a long time, for example, the vehicle detection unit 202 detects vehicles parked in each parking slot from the image. Then, the vehicle detection unit 202 can detect whether a vehicle is staying by comparing edge images of vehicles for the same parking slot. Note that comparing the edge images of the vehicle means, for example, comparing binary images of the edges and ends of the vehicle. The vehicle detection unit 202 repeatedly performs such a comparison to detect a vehicle that has been parked for a predetermined period of time or longer.

As another method for detecting vehicles parked for a long time, for example, the vehicle detection unit 202 detects vehicles parked in each parking slot from the image. Then, the vehicle detection unit 202 compares the color information of the vehicles detected from the images at each first time interval. As the process of comparing color information, for example, the vehicle detection unit 202 may determine whether the color distribution, which is the color information of the vehicles, is similar for the same parking slot. If the color distributions are similar, the vehicle detection unit 202 determines that the vehicles are the same vehicle. The vehicle detection unit 202 repeatedly performs such a comparison to detect a vehicle that has been parked for a predetermined period of time or longer.

Here, the vehicle detection unit 202 calculates a score for each of the plurality of methods for detecting a vehicle parked for a long time to determine whether the vehicle is the same, and determines whether the vehicle is the same based on the overall score of the plurality of methods. It may be determined whether the

The output control unit 205 may notify an employee or a supervisor when a vehicle parked for a long time is detected. For example, when displaying the captured image on the terminal device 21, the output control unit 205 may display a vehicle that has been parked for a long time and other vehicles in a distinguishable manner. More specifically, when displaying the captured image on the terminal device 21, the output control unit 205 displays vehicles parked for a long time and other vehicles in different display modes. As an example of displaying in different display modes, in the image, vehicles may be displayed in a green frame, and vehicles parked for a long time may be displayed in a red frame. As another example, the output control unit 205 may highlight a vehicle that has been parked for a long time in the image by surrounding it with a frame of a predetermined color. Note that the output control unit 205 may display images at each first time interval as thumbnails. This allows users such as store clerks and security guards to visually confirm whether the vehicle was actually stopped a predetermined time ago.

Additionally, the output control unit 205 may notify employees and supervisors using vehicle identification information. The vehicle identification information may be detected by the vehicle detection unit 202. Specifically, for example, the vehicle detection unit 202 detects vehicle identification information from the captured image. Vehicle identification information may be, for example, the number included in the license plate of the vehicle, the type of vehicle, the shape of the vehicle, the color of the vehicle, or any information that can identify the vehicle. , not particularly limited. Then, the output control unit 205 causes the vehicle identification information to be displayed on the terminal device 21.

Further, when a vehicle parked for a long time is detected, the owner detection unit 204 detects the owner of the vehicle based on images at each second time interval. The owner detection unit 204 detects the owner of the vehicle based on each acquired image. The example in which the owner detection unit 204 detects the owner of the people included in the image is as described in Embodiment 1, and detailed explanation will be omitted.

Next, when the owner is detected, the output control unit 205 notifies the owner. Thereby, the output control unit 205 can notify the owner that the vehicle is being monitored at the timing when the owner returns to the vehicle or at the timing when the owner starts the vehicle.

Additionally, the output control unit 205 may notify the owner from the time the owner is detected until the vehicle leaves. Specifically, for example, as described above, the vehicle detection unit 202 detects the disappearance of a vehicle that has been parked for a long time based on images at each second time interval. Then, the output control unit 205 notifies the owner from the time the owner is detected until the disappearance of the vehicle is detected.

Next, a specific notification method will be explained. For example, the output control unit 205 notifies the owner via the output device. The output device may be a device installed in a parking lot. The output device may be a display device, a projection device, an audio output device, a lighting device, etc., and is not particularly limited.

First, an example will be described in which the output control unit 205 notifies the owner via the display device. The display device may be, for example, a signage installed in a parking lot. The output control unit 205 causes the display device to display the notification. Displaying the notification may be, for example, displaying a predetermined message representing the notification, and is not particularly limited. Note that the output control unit 205 may display information that can identify the vehicle together with a predetermined message. The information that can identify the vehicle may be an image of the vehicle, and is not particularly limited to the type of vehicle, the color of the vehicle, the position of the parking frame where the vehicle is parked, etc.

FIG. 6 is an explanatory diagram showing an example in which a predetermined message representing notification is displayed on the display device. In FIG. 6, the display device displays a predetermined message. In FIG. 6, the predetermined message is "The vehicle has been parked for a long time."　

Although FIG. 6 shows an example in which the number of display devices installed in the parking lot is one, the number of display devices is not particularly limited. For example, a display device may be provided for each parking slot.

Next, returning to the description of FIG. 5, an example will be described in which the output control unit 205 notifies the owner via the projection device. For example, the output control unit 205 causes the projection device to project the notification at a position related to the detected vehicle. Projecting the notification may be, for example, projecting a predetermined message regarding the notification, and is not particularly limited. The location on the vehicle is not particularly limited as long as it is easily visible to the owner. For example, the detected position related to the vehicle may be a window of the vehicle, the ground near the vehicle, or a wall near the vehicle, and is not particularly limited. Note that the orientation of the predetermined message is not particularly limited as long as it is easy for the owner to see.

For example, the identifying unit 206 may identify a position related to the detected vehicle from the captured image. For example, when projecting the notification on the rear window, the identifying unit 206 may identify the detected position of the rear window of the vehicle from the captured image.

FIG. 7 is an explanatory diagram showing an example in which a notification is projected onto the rear window of a vehicle. The output control unit 205 causes a predetermined message to be projected on the specified position on the rear glass. The projection device projects a predetermined message on the specified rear glass position under the control of the output control unit 205.

Returning to the description of FIG. 5, for example, when projecting on the ground in the direction of travel of the vehicle, the identification unit 206 may identify the detected position of the ground in the direction of travel of the vehicle from the captured image. The traveling direction of the vehicle may be specified by the orientation of the vehicle, the movement of the vehicle, the position of the parking slot in the parking lot, the positional relationship between the exit of the parking lot and the parking frame, etc. may be done.

FIG. 8 is an explanatory diagram showing an example in which a notification is projected on the ground in the direction of travel of the vehicle. In FIG. 8, since there is a store on the windshield side of the vehicle, the specifying unit 206 specifies the direction on the rear glass side of the vehicle as the traveling direction of the vehicle. Then, the output control unit 205 causes a predetermined message to be projected on the ground position in the specified direction of travel. The projection device projects a predetermined message at the specified position on the ground in the direction of travel under the control of the output control unit 205.

Next, returning to the description of FIG. 5, an example will be described in which the output control unit 205 notifies the owner via the lighting device. For example, each parking slot may be provided with a lighting device in advance. The number of lighting devices is not particularly limited. For example, a plurality of lighting devices may be installed along the parking frame. The output control unit 205 controls the lighting device in such a way that it is possible to identify that it is a notification. As an example of making it possible to identify that it is a notification, the output control unit 205 controls lighting, blinking, lighting color, etc. of the lighting device.

FIG. 9 is an explanatory diagram showing an example in which notification is performed by controlling a lighting device. In FIG. 9, a plurality of lighting devices are installed in the parking frame along a line representing the parking frame. In FIG. 9, the plurality of lighting devices are turned off. Then, the output control unit 205 turns on the lighting device installed along the parking frame of the vehicle parked for a long time. In FIG. 9, the lighting device surrounding the parking frame of a vehicle parked for a long time is turned on. As a result, the lighting devices around the vehicle of the detected owner are lit and the other lighting devices are not lit, so the owner can easily confirm that he/she is receiving some sort of notification.

Returning to the description of FIG. 5, an example will be described in which the output control unit 205 notifies the owner via the audio output device. The audio output device is, for example, a speaker. For example, the output control unit 205 may cause the audio output device to output the notification as audio.

This concludes the explanation of the example of notifying the owner via the output device.

Furthermore, for example, the output control unit 205 may perform notification according to the time from when the start of parking of the vehicle is detected until when the owner is detected. For example, messages such as warning texts for each time may be stored in advance in a table or the like. The output control unit 205 may output warning messages by time based on the table. More specifically, for example, when the vehicle has been parked for about 10 minutes, the output control unit 205 notifies that the vehicle has been parked for a long time. For example, if the vehicle has been parked for more than 30 minutes, the output control unit 205 will notify that the vehicle has been parked without permission. The time period is not limited to the time from when the start of parking of the vehicle is detected until the owner is detected, but may be the time from when the start of parking of the vehicle is detected until the vehicle leaves the parking slot.

Furthermore, for example, the output control unit 205 may end the notification when a vehicle that has been parked for a long time is no longer detected from the parking slot. Specifically, for example, the output control unit 205 may end the notification when a vehicle that has been parked for a long time leaves the parking lot. More specifically, for example, the vehicle detection unit 202 detects the disappearance of a vehicle that has been parked for a long time from a parking slot or a parking lot based on images at each second time interval. Then, when the disappearance of the vehicle is detected, the output control unit 205 ends the notification. Here, for example, even if images are stored in the captured image DB 2001 at every second time interval, the vehicle detection unit 202 determines whether the vehicle has been parked for a long time based on the images at every first time interval. Detect vehicles.

For example, if the vehicle does not leave the parking lot even after a second predetermined period of time has elapsed since the owner was detected, the output control unit 205 uses vehicle identification information that can be detected from the captured image. You may report it. Specifically, for example, if the vehicle does not leave the parking lot even after a second predetermined period of time has passed since the owner was detected, the vehicle detection unit 202 detects the identification information of the vehicle from the captured image. . Vehicle identification information may be, for example, the number included in the license plate of the vehicle, the type of vehicle, the shape of the vehicle, the color of the vehicle, or any information that can identify the vehicle. , not particularly limited. Then, the output control unit 205 makes a notification using the vehicle identification information.

Further, the output control unit 205 is not limited to the example of notifying the owner, but may also notify an employee of the facility or a parking lot supervisor. For example, the output control unit 205 notifies facility employees and parking lot supervisors via the terminal device 21. More specifically, for example, the output control unit 205 causes the output device of the terminal device 21 to output a predetermined message representing the notification. The output device may be a display device or an audio output device.

Furthermore, for example, when the owner of a vehicle parked for a long time is detected, the imaging control unit 203 returns the control performed on at least one of the imaging device 22 and the storage unit 207. Here, returning control means making the time interval longer than the second time interval. The long time interval may be the first time interval or another time interval. For example, although the first time interval was 5 minutes, it may be changed to 7 minutes.

The process of returning control will be described by taking as an example a case where control is performed to switch the imaging by the imaging device 22 from an image to a moving image. For example, when the owner of a vehicle that has been parked for a long time is detected, the imaging control unit 203 performs control to switch from a video to an image. The process of returning control will be described using as an example a case where control is performed to change the storage interval from the first time interval to the second time interval. For example, when the owner of a vehicle that has been parked for a long time is detected, the imaging control unit 203 performs control to switch from a video to an image.

Furthermore, when returning the control, the imaging control unit 203 may return the control in stages starting from the second time interval. Specifically, for example, when returning control, the imaging control unit 203 returns the control in stages from the second time interval to the first time interval. Specifically, for example, when the first time interval is 5 minutes and the second time interval is 1 second, the imaging control unit 203 sets the first time interval to 10 seconds, 20 seconds, 30 seconds, 1 minute, etc. Gradually return from the 2 hour interval to the 1st hour interval.

Alternatively, for example, when a vehicle parked for a long time is no longer detected from the parking slot, the imaging control unit 203 returns the control performed on at least one of the imaging device 22 and the storage unit 207. The return process is as described above.

(flowchart)
10 and 11 are flowcharts illustrating an example of the operation of the parking lot management system 20 according to the second embodiment. In FIGS. 10 and 11, an example will be described in which a parking lot is provided with a parking slot in which one vehicle can be parked.

The acquisition unit 201 acquires a new image of the parking frame captured by the imaging device 22 from the captured image DB 2001 (step S201). The vehicle detection unit 202 determines whether a vehicle parked in at least one of the plurality of parking slots for a predetermined period of time or more is detected based on the images for each first time interval (step S202). If a vehicle is not detected (step S202: No), the acquisition unit 201 returns to step S201 and acquires a new image from the captured image DB 2001. Thereby, the acquisition unit 201 can acquire images at each first time interval. Then, when a new image is acquired, in step S202, the vehicle detection unit 202 detects a vehicle that has been parked in at least one of the plurality of parking spaces for a predetermined period of time or longer based on the images at each first time interval. To detect.

On the other hand, if a vehicle is detected (step S202: Yes), the imaging control unit 203 controls at least one of the storage unit 207 and the imaging device 22 (step S203).

The acquisition unit 201 acquires a new image from the captured image DB 2001 (step S204). Next, the owner detection unit 204 determines whether the owner of the vehicle has been detected based on the images at each second time interval (step S205). If the owner has not been detected (step S205: No), the acquisition unit 201 returns to step S204 and acquires a new image from the captured image DB 2001. Thereby, the acquisition unit 201 can acquire images at each second time interval.

On the other hand, if the owner is detected (step S205: Yes), the output control unit 205 notifies the owner (step S206). In step S206, the output control unit 205 notifies the owner via the output device. Next, the acquisition unit 201 acquires a new image from the captured image DB 2001 (step S207). The vehicle detection unit 202 determines whether the vehicle that has been parked for a long time has left, based on the images at each second time interval (step S208). In step S208, the vehicle detection unit 202 determines whether it has been detected that a vehicle that has been parked for a long time has disappeared from the parking slot.

If it is determined that the vehicle has not left (step S208: No), the acquisition unit 201 returns to step S207 and acquires a new image from the captured image DB 2001. If it is determined that the vehicle has left (step S208: Yes), the output control unit 205 ends the notification (step S209). Further, the imaging control unit 203 returns control to at least one of the storage unit 207 and the imaging device 22 (step S210). In step S210, the imaging control unit 203 performs control to enable acquisition of images at each first time interval. After step S210, the acquisition unit 201 returns to step S201. Note that the flowchart may be ended as appropriate.

Here, for example, if multiple parking spaces are provided in a parking lot, even if a vehicle parked for a long time in one parking space is detected, it will also be detected that a vehicle is parked for a long time in other parking spaces. Monitoring will be carried out to see if there are any vehicles in use. Even if a vehicle parked for a long time in a certain parking slot is detected, steps S201 and S202 are repeatedly performed in addition to steps S203 to S210. Further, when the notification to the owner of a certain parking slot is completed, it is detected that there is a vehicle parked for a long time in another parking slot, and step S210 may not be performed. In this way, the order of each step in the flowchart may be changed as appropriate, or may be skipped as appropriate.

As described above, in the second embodiment, the parking lot management system 20 ends the notification when it is detected that the vehicle has left the parking slot. As a result, the notification is sent from when the owner is near or inside the vehicle until the vehicle leaves the parking slot, so there are cases where the notification is made continuously from the timing when a vehicle that has been parked for a long time is detected. In comparison, notification can be suppressed. In this way, when notification is suppressed, necessary notification can be performed even if the number of output devices is small. Therefore, when providing notification via the output device, it is possible to reduce the number of output devices relative to the number of parking spaces. Further, the parking lot management system 20 returns control to at least one of the storage unit 207 and the imaging device 22 when it is detected that the detected vehicle has left the parking slot. Thereby, when storing captured images in a storage unit such as the captured image DB 2001, it is possible to narrow down the images to be stored in the storage unit. Therefore, the cost can be reduced compared to the case where moving images are constantly stored in a storage means or the like.

Furthermore, when the owner is detected, the parking lot management system 20 returns control to at least one of the storage unit 207 and the imaging device 22. Thereby, when storing captured images in the storage means, it is possible to narrow down the images to be stored in the storage means. Therefore, the cost can be reduced compared to the case where moving images are constantly stored in a storage means or the like.

Additionally, the parking lot management system 20 notifies the owner via an output device installed in the parking lot. For example, the output device is a display device. By displaying the notification on the display device, the owner can more easily confirm that he or she is being monitored. Therefore, it is possible to prevent the vehicle from being parked for a long time.

For example, the output device is a projection device. The parking lot management system 20 causes a projection device to project a notification at a position related to the detected vehicle. The location may be the window glass of the vehicle or the ground in the direction of travel of the vehicle. This makes it easier for the owner to confirm that he or she is being monitored. Therefore, it is possible to prevent the vehicle from being parked for a long time.　

For example, the output device is a lighting device. The parking lot management system 20 controls the lighting device so that it can be identified that it is a notification. This makes it easier for the owner to confirm that he or she is being monitored. Therefore, it is possible to prevent the vehicle from being parked for a long time.

Furthermore, when a vehicle that has been parked for a long time is detected, the parking lot management system 20 notifies at least one of the employees and supervisors of the facility that has the parking space. This allows employees and supervisors to check vehicles that have been parked for long periods of time, even if they are not constantly monitoring them.

Furthermore, when the owner of a vehicle parked for a long time is detected, the parking lot management system 20 notifies at least one of the employee and the supervisor of the facility that has the parking space. This allows employees and supervisors to confirm the owner of a vehicle that has been parked for a long time, even if they are not constantly monitoring the vehicle.

This concludes the description of each embodiment. Each embodiment may be modified and used. Each embodiment may be used in combination as appropriate. Moreover, in each embodiment, the parking lot management system may have a configuration in which each functional unit and a part of information are included.

Furthermore, each embodiment is not limited to the example described above, and can be modified in various ways. Further, the configuration of the parking lot management system in each embodiment is not particularly limited. For example, the parking lot management system may be realized by one device such as one terminal device or one server. For example, when each functional part of the parking lot management system is realized by one device, the one device may be called a parking lot management device, an information processing device, or the like. Alternatively, the parking lot management system in each embodiment may be realized by different devices for each function or data. For example, each functional unit of the parking lot management system may be configured with a plurality of servers. For example, the parking lot management system 20 according to the second embodiment may be realized by a database server including the storage unit 207 and the captured image DB 2001, and a server having each functional unit other than the storage unit 207.

In each embodiment, each piece of information and each DB may include part of the above-mentioned information. Moreover, each piece of information and each DB may include information other than the above-mentioned information. Each piece of information and each DB may be divided into a plurality of DBs and a plurality of pieces of information in more detail. In this way, the method of implementing each piece of information and each DB is not particularly limited.

Further, for example, in each embodiment, the process of generating screen information etc. to be displayed on the terminal device may be performed by the output control unit of the parking lot management system. Further, this process may be performed by a terminal device.

Additionally, the processor 801 loads programs stored in the storage device 804, ROM 802, etc. The processor 801 then executes each process coded in the program. Furthermore, the processor 801 may download various programs via the communication network NT. Further, the processor 801 functions as part or all of the computer 80. The processor 801 may then execute the processes or instructions in the illustrated flowchart based on the program.

The communication interface 805 is connected to a communication network NT such as a LAN (Local Area Network) or a WAN (Wide Area Network) through a wireless or wired communication line. Note that the communication network NT may be composed of a plurality of communication networks NT. Thereby, the computer 80 is connected to an external device or an external computer 80 via the communication network NT. Communication interface 805 serves as an interface between communication network NT and the inside of computer 80 . The communication interface 805 controls input and output of data from external devices and the external computer 80.

Further, the input/output interface 806 is connected to at least one of an input device, an output device, and an input/output device. The connection method may be wireless or wired. Examples of the input device include a keyboard, a mouse, and a microphone. Examples of the output device include a display device, a lighting device, and a speaker that outputs audio. Further, examples of the input/output device include a touch panel display. Note that the input device, output device, input/output device, etc. may be built into the computer 80 or may be externally attached.

The hardware configuration of the computer 80 is an example. Computer 80 may include some of the components shown in FIG. Computer 80 may include components other than those shown in FIG. For example, the computer 80 may include a drive device or the like. Then, the processor 801 may read programs and data stored in a recording medium attached to a drive device or the like to the RAM 803. Examples of non-temporary tangible recording media include optical disks, flexible disks, magneto-optical disks, USB (Universal Serial Bus) memories, and the like. Further, as described above, for example, the computer 80 may include an input device such as a keyboard and a mouse. Computer 80 may have an output device such as a display. Further, the computer 80 may each have an input device, an output device, and an input/output device.

Additionally, the computer 80 may include various sensors (not shown). The type of sensor is not particularly limited. Further, the computer 80 may include an imaging device capable of capturing images and videos.

This concludes the explanation of the hardware configuration of each device. Furthermore, there are various variations in the method of implementing each device. For example, each device may be realized by an arbitrary combination of a computer and a program, each of which is different for each component. Further, the plurality of components included in each device may be realized by an arbitrary combination of one computer and a program.

Additionally, some or all of the components of each device may be realized by application-specific circuits. Further, a part or all of each component of each device may be realized by a general-purpose circuit including a processor such as an FPGA (Field Programmable Gate Array). Further, some or all of the components of each device may be realized by a combination of application-specific circuits, general-purpose circuits, and the like. Also, these circuits may be a single integrated circuit. Alternatively, these circuits may be divided into multiple integrated circuits. Further, the plurality of integrated circuits may be configured by being connected via a bus or the like.

Further, in the case where a part or all of each component of each device is realized by a plurality of computers, circuits, etc., the plurality of computers, circuits, etc. may be arranged centrally or in a distributed arrangement.

The parking lot management method described in each embodiment is realized by being executed by the parking lot management system. Further, for example, the parking lot management method is realized by a computer such as a server or a terminal device executing a program prepared in advance. The programs described in each embodiment are recorded on a computer-readable recording medium such as an HDD, SSD, flexible disk, optical disk, magneto-optical disk, or USB memory. Then, the program is executed by being read from the recording medium by the computer. The program may also be distributed via the communications network NT.
