The parking space monitoring device 20 has a local communication unit 24 , a camera 21 , a display unit 22 , a speaker 23 , a storage unit 25 and a control unit 26 . The control unit 26 has, for example, a CPU, RAM, and ROM. The storage unit 25 is a non-volatile storage device, such as an HDD (Hard Disk Drive), flash memory, or other solid-state memory.

The CPU of the control unit 26 loads a predetermined program according to the present technology stored in the storage unit 25 or the like into the RAM and executes it, so that the vehicle recognition unit 27, the license plate reading unit 28, and the door open detection are configured as software blocks. A unit 29, a person detection unit 30, a sound generation unit 31, and an image generation unit 32 are configured. The information processing method according to the present technology is executed by cooperation of these blocks, the camera 21, the display unit 22, and the like. Of course, dedicated hardware such as an IC (integrated circuit) may be used to implement each of the above blocks.

The vehicle recognition unit 27 detects the entry and exit of the vehicle 5 with respect to the parking space 66 based on the captured image captured by the camera 21 . Since the entry/exit of the vehicle 5 is detected based on the captured image captured by the camera 21, high detection accuracy can be achieved. Moreover, since there is no need to newly install an infrared sensor or the like, it is possible to sufficiently reduce equipment costs. The vehicle recognition unit 27 functions as an entry detection unit in this embodiment.

The number reading unit 28 generates license plate information (land transport branch name, classification number, hiragana, 4-digit serial number, etc.) by OCR (Optical Character Recognition) processing or the like from the photographed license plate image. The license plate information is stored in the storage unit 25 together with the image data (still image) of the vehicle 5 that has been recognized, and is also transmitted to the fee adjustment machine 64 and the like. At this time, the image data may be compressed by any compression technique.

The door open detector 29 detects the open state of the door of the vehicle 5 based on the photographed image of the vehicle 5 parked in the parking space 66 . In this embodiment, the door open detection unit 29 has a contour extraction unit and an area calculation unit (both not shown), which function to detect the open state of the door. The door open detector 29 functions as an open state detector in this embodiment.

FIG. 5 is a schematic diagram for explaining an example of detection of the open state of the door. First, an image of the vehicle 5 parked in the parking space 66 is acquired (FIG. 5A). The image of the vehicle 5 is binarized, and edge enhancement processing or the like is performed as appropriate (FIG. 5B). Based on this binarized image, the license plate information may be generated by the license plate reader 28 .

The outline 4 of the outer shape of the vehicle 5 is extracted by the outline extractor of the door open detector 29 (FIG. 5C). A specific algorithm for contour extraction is not limited, and any image analysis technique or the like may be used. Also, the method of extracting the contour 4 may be learned by machine learning or the like. Based on the closed two-dimensional shape of the contour 4 of the vehicle 5 , the area within the contour 4 is calculated by the area calculation section of the door open detection section 29 .

Each process of image acquisition, binarization (edge enhancement), contour extraction, and area calculation shown in FIGS. executed.

The open state of the door 7 of the vehicle 5 is detected when a temporal increase in the area within the contour 4 is detected, as shown in FIG. 5D. Thus, it is possible to easily detect the open state of the door 7 of the vehicle 5 based on the temporal change in the area within the contour 4 . Of course, it is desirable to detect the open state of the door 7 based on the temporal change in the area of only a specific portion within the contour 4 . Specifically, when the area of at least one side surface in the contour 4 increases with the lapse of time, it is preferable to detect it based on the time required for the increase and the amount of increase. In addition, since there is no need to provide another sensor or the like for detecting door opening, it is possible to sufficiently reduce equipment costs.

The person detection unit 30 detects a person from the captured image captured by the camera 21 . A specific algorithm for person detection is not limited, and any detection method may be adopted. Also, the detection method may be learned by machine learning or the like. A security system using person detection will be described in detail in a second embodiment.

The audio generator 31 generates audio data to be output from the speaker 23 . The image generation section 32 generates image data to be displayed on the display section 22 . The audio data and image data are typically data on guidance information regarding the use of the parking lot 15 . For example, audio data, image data, and the like related to a parking fee settlement method and the like are stored in the storage unit 25, and are read by the audio generation unit 31 and the image generation unit 32 as appropriate. Of course, data about guidance information different from the settlement method is also generated as appropriate.

In the present embodiment, voice data and image data of the guidance information are appropriately generated based on the detection result of the door open detection section 29 . The user of the parking lot 15 is notified of the guidance information by the display unit 22 and the speaker 23 .

[Notification method of guidance information]
FIG. 6 is a flowchart showing an example of notification of guidance information by the parking space monitoring device 20. As shown in FIG. FIG. 7 is a schematic diagram showing an example of guidance information notified by the display unit 22 and the speaker 23. As shown in FIG.

The parking space 66 is constantly photographed by the camera 21, and entry of the vehicle 5 into the parking space 66 is monitored (step 101). When the entry of the vehicle 5 is detected and the vehicle 5 is recognized (YES in step 101), the entry date and time, license plate information, and image data are sent to the controller 65 together with the parking space number (step 102). These pieces of information are also transmitted to the fee adjustment machine 64 and the parking lot management device 40 via the control device 65 . The control device 65 and the charge settlement machine 64 store the received information in their memories. The parking lot management device 40 stores the received information in the vehicle presence DB 43 and the image DB 45 .

Further, when the vehicle 5 is recognized, notification of guidance information to the user is started (step 103). In the present embodiment, as shown in FIG. 7A, the display unit 22 displays an initial screen including the elapsed time from warehousing. After the sound effect, the speaker 23 outputs a voice such as "welcome".

The open state of the door of the vehicle 5 in the parking space 66 is monitored (step 104). When the open state of the door is detected by the door open detector 29 of the parking space monitoring device 20 (YES in step 104), the initial notification of the settlement method is executed (step 105).

In this embodiment, as shown in FIG. 7B, a warning screen is displayed on the display unit 22 requesting payment before leaving the garage. From the speaker 23, a voice requesting payment before leaving the garage is similarly output following the warning sound. In addition, as shown in FIG. 7B, the expression "settlement before leaving the parking lot 15" may be used. Of course any other representation may be used.

Thereafter, it is repeatedly monitored whether the user returns to the vehicle 5 or not. In this embodiment, the presence or absence of reception of settlement information transmitted by the charge settlement machine 64 is monitored (step 106). The settlement information includes information as to whether or not the parking fee has been settled. If it has been settled, the settlement information including the date and time of settlement and the settlement fee is transmitted from the fee settlement machine 64 (step 107). The settlement information may be obtained by inquiring the charge settlement machine 64 from the parking space monitoring device 20 at predetermined time intervals. Alternatively, the payment information may be transmitted from the charge adjustment machine 64 to the parking space monitoring device 20 at the event of payment completion. The local communication unit 24 of the parking space monitoring device 20 that receives the settlement information functions as an acquisition unit.

During this time, it is monitored at step 108 whether or not the payment has been completed, and at step 109, the open state of the door of the vehicle 5 is monitored. Note that, as shown in FIG. 7C , the image display by the display unit 22 and the sound output by the speaker 23 are not performed in the state before settlement.

If the user has made payment before leaving the garage, payment information including the date and time of payment and the payment fee is received in step 106 . Accordingly, it is determined that payment has been completed (YES in step 108), and exit of the vehicle 5 is monitored based on the image captured by the camera 21 (step 110).

When the exit of the vehicle 5 from the parking space 66 is detected (YES in step 110), the notification of the guidance information ends (step 111). Then, the entry information is transmitted to the parking lot management device 40 via the control device 65, stored in the history DB 44, and the process ends.

For example, if the door is opened while the parking fee has not yet been settled (from NO in step 108 to YES in step 109), the parking fee will be settled. Re-notification of the method is performed (step 113).

In the present embodiment, as shown in FIG. 7D, a warning screen is displayed on the display unit 22, including the message that the payment has not been made and the request for the payment before leaving the garage. Similarly, from the speaker 23, voices indicating that the payment has not been made and that payment is requested before leaving the garage are output following the warning sound.

If the user notices that the account has not been settled and settles the account, the processing after YES in step 108 described above is executed. Although not shown in the flow chart, when the open state of the door is detected in the state where payment has been completed, guidance information to the effect that the user is grateful for the use is notified as shown in FIG. 7E. The send-off screen shown in FIG. 7E displays the remaining time from the completion of payment until the vehicle leaves. For example, if the exit of the vehicle 5 is not detected even after a predetermined period of time has elapsed after payment, charging of the parking fee is started again. Alternatively, license plate information or the like is registered as unauthorized use.

As described above, in the parking lot management system 500 according to the present embodiment, guide information including the payment method and the like is appropriately notified based on the detection result of the open state of the door of the vehicle 5 . This makes it possible to provide appropriate guidance information at the timing when it should be notified to the user. For example, it is assumed that guidance information is notified when the vehicle 5 enters or approaches. In this case, there may be a case where the guidance information is not transmitted to the driver or fellow passengers, for example, when the doors and windows are closed and music or the like is being played. In this case, the user is not notified of the request for payment before leaving the parking lot, and the number of leaving the parking lot without payment increases, which may increase the burden of collecting the parking fee. Also, it takes time for the user to grasp the payment method, which reduces convenience.

In this embodiment, when the doors of the vehicle 5 are opened, guidance information is notified to the user. Therefore, it is possible to appropriately convey the settlement method and the like at the timing when notification should be given by image display and sound, and it is possible to publicize the usage method of the settlement before leaving the garage. As a result, it is possible to sufficiently prevent leaving the parking lot without payment, and it is possible to sufficiently reduce the burden of collecting the parking fee. In addition, it is possible to exhibit extremely high convenience for users who use the parking lot 15 for the first time and users who are unfamiliar with how to use it.

As shown in FIGS. 7D and 7E, the guidance information is appropriately changed according to the payment status of the user, specifically, whether payment is made before leaving the garage. This makes it possible to provide guidance information with content appropriate for the user. For example, even if the payment before leaving the garage is carelessly forgotten, the notification is given again in step 113, so that the payment before leaving the garage can be smoothly performed. Guidance information other than the settlement method may be provided.

When the vehicle 5 enters the parking space 66 and the door is first detected to be open, the initial notification is performed. Then, when the door is opened after that, another notification or the like is executed. In this way, it is possible to change the guidance information based on the result of detecting the entry of the vehicle 5, and it is possible to provide various variations of the guidance information. For example, the time from detection of entry may be measured, and guidance information may be announced according to the elapsed time.

<Second embodiment>
A parking lot management system according to a second embodiment of the present invention will be described. In the following description, the description of the same parts as the configuration and operation of the parking lot management system 500 described in the above embodiment will be omitted or simplified.

FIG. 8 is a plan view showing a specific configuration example of the parking lot according to this embodiment. FIG. 9 is a schematic diagram showing an example of a photographed image of a vehicle photographed by a camera of the parking space monitoring device.

In the parking lot 215 according to this embodiment, the position of the parking space monitoring device 220 arranged in the parking space 66 is different from that in the first embodiment. As shown in FIG. 8, the parking space monitoring device 220 is located near the left end of the parking space 66 when viewed from the entrance 71 toward the rear portion 72 (hereinafter referred to as the entry direction of the vehicle 5). placed in Therefore, the parking space monitoring device 220 is arranged near the left rear corner of the rectangular parking space 66 .

The photographing range R of the camera 21 is set obliquely from the left end of the rear portion 72 toward the right end of the entrance 71 . As shown in FIG. 9, the left and right angles of view of the imaging range R are set so that the license plate 2 and the right side 6a of the vehicle 5 parked in the parking space 66 are included. Also, the angle of view of the shooting range R is the left side of another vehicle 5a parked in another parking space 80a adjacent to the side on which the parking space monitoring device 20 is arranged, that is, adjacent to the right side (left side when viewed from the approach direction). It is arranged so that the surface 6b is included.

The angle of view of the imaging range R is set so as to include the right side 6a of another vehicle 5b parked in another parking space 80b located diagonally forward right of the parking space 66. FIG. Further, the angle of view of the photographing range R is set so as to include the left side (not shown) of another vehicle parked in another parking space 80c located opposite the parking space 66. As shown in FIG.

The other parking space 80b located diagonally forward right of the parking space 66 and the other parking space 80c located facing each other are such that the entry direction of the vehicle 5 is the front-rear direction, the rear part 72 is the rear side, and the entrance 71 is the front side. , it corresponds to another parking space located forward of the entrance 71 . For example, for the number 10 parking space 66, the number 4 parking space 66 corresponds to another parking space 80b located diagonally forward right. Also, the third parking space 66 corresponds to another parking space 80c located opposite.

Thus, in this embodiment, the camera 21 is provided in the parking space monitoring device 220 so as to capture at least one side surface of the other vehicles 5a-5c parked in the other parking spaces 80a-80c.

The door open detector 29 of the parking space monitoring device 220 detects the open state of the door on the right side 6a of the vehicle 5 parked in the parking space 66 based on the captured image of the vehicle 5 captured by the camera 21 . The door open detector 29 detects the open state of the door on the left side 6b of another vehicle 5a parked in another parking space 80a adjacent to the right. The door open detection unit 29 detects the open state of the door of the right side 6a of the other vehicle 5b parked in the other parking space 80b located diagonally forward right. Further, the door open detection unit 29 detects the open state of the door on the left side 6b of the other vehicle 5c parked in the other parking space 80c located opposite.

For example, the contours of the vehicle 5 and the other vehicles 5a to 5c are detected, and the open state of the door of each vehicle can be detected based on the temporal change in the area of each contour. Of course, other algorithms or the like may be used.

The door open detection unit 29 stores the door open detection result of each vehicle in association with the number of its own parking space 66 and the number of each of the other parking spaces 80a to 80c. Then, the door detection result for each vehicle is transmitted to the control device 65 via the local communication unit 24 functioning as a communication unit. The control device 65 transmits the received detection result to the parking space monitoring device 220 arranged in the parking space 66 corresponding to the parking space number.

As a result, each parking space monitoring device 220 detects both side surfaces 6a of the vehicle 5 based on both the detection result of its own door opening detection unit 29 and the detection result of the door opening detection unit 29 of another parking space monitoring device 220. and the open state of the door 6b can be detected with high accuracy. That is, by interlocking a plurality of parking space monitoring devices 220, it is possible to improve the detection accuracy of the open state of the door of the vehicle 5. FIG. In addition, it is possible to precisely detect the open state of both the left and right side doors of the vehicle in all the parking spaces 66 with the minimum number of parking space monitoring devices 220 and cameras 21 .

For example, it is assumed that the open state of the door on the right side 6a of the vehicle 5 shown in FIG. 9 is detected. In this case, from another parking space monitoring device 220 arranged in another parking space 80b diagonally forward right, the door on the right side 6a of the vehicle 5 (another vehicle diagonally forward right when viewed from the parking space 80b side) is detected. It is determined whether an open state has been detected. When the determination is affirmative, it is determined that the door on the right side 6a of the vehicle 5 is open. Such processing is also possible. The reliability of the detection results for the other vehicles 5a to 5b is calculated, and if the reliability is lower than a predetermined threshold, the detection results may be ignored.

It should be noted that, depending on the installation position and angle of the camera 21, it is possible to sufficiently suppress overlapping of parked vehicles. Also, it is sufficiently possible to distinguish each vehicle based on the position, shape, etc. of the outline, etc., using a well-known image analysis technique or the like.

As described above, in the present embodiment, the parking space monitoring device 220 is arranged in the vicinity of the left end of the rear portion 72 when viewed from the entering direction of the vehicle 5 . This makes it easier for the driver who drives the vehicle 5 to view the display unit 22 . In addition, the sound from the speaker is emitted to the driver without being blocked by the vehicle body. As a result, it is possible to sufficiently convey guidance information including payment methods and the like.

In addition, a plurality of parking space monitoring devices 220 communicate door opening detection results with each other and cooperate to detect door opening of each vehicle 5, so that very high detection results can be obtained.

Other parking spaces included in the imaging range R are not limited to those shown in FIG. For example, only vehicles in adjacent parking spaces can be photographed, or only vehicles in opposite parking spaces can be photographed. Even in this case, it is possible to detect the opening of the door with high accuracy using the detection result of another parking space monitoring device 220 .

Further, the position where the parking space monitoring device is arranged is not limited, and the monitoring space monitoring device may be arranged in the vicinity of the end on the right side as seen from the entering direction of the vehicle 5 . In addition, the parking space monitoring device may be arranged at any position. Further, similar detection processing and communication of the detection results may be performed for the image of the surveillance camera 62 placed near the entry/exit gate 61 .

FIG. 10 is a flow chart showing an example of a suspicious person monitoring method in this parking lot system. FIG. 11 is a schematic diagram showing an example of a captured image including a person.

The person detection unit 30 shown in FIG. 4 monitors whether or not a person is detected from the image captured by the camera 21 of the parking space monitoring device 20 (220) (step 201). When the person F is detected as shown in FIG. 11, the image is transmitted to the control device 65 or the like (step 202). The image transmitted from the parking space monitoring device 20 (220) is analyzed by the control device 65 or the like (step 203). This image analysis function may be provided in any of the control device 65 , the fee settlement machine 64 , and the parking management device 40 on the network 1 .

FIG. 12 is a flow chart showing an example of image analysis. Upon receiving an image in which a person F has been detected (step 301), the parking spaces 66 associated with the person F are analyzed (step 302). The parking space 66 associated with person F is typically the parking space 66 to which person F is closest. For example, when there is one parking space 66 to be photographed by the camera 21 of the parking space monitoring device 20 as in the first embodiment, the parking space 66 directly becomes the parking space related to the person F. .

As described in the second embodiment, when the other parking spaces 80a to 80c are also photographed, the parking space 66 related to the person F is analyzed from the plurality of parking spaces 66. FIG. For example, the parking space 66 closest to the person F is selected as the parking space 66 associated with the person F, depending on the position, size, etc. of the person F in the image. In addition, the parking space 66 most conscious of the person F may be analyzed based on the direction of the person F's face, line of sight, etc., and may be selected as the parking space 66 related to the person F. Note that the analysis of the parking space 66 associated with the person may be omitted.

It is analyzed whether or not the person F in the image is a suspicious person (step 303). For example, features such as the height and clothes of the photographed person F are extracted, and the person who is considered to be the same person from images photographed not only by the same camera 21 but also by the camera 21 of another parking space monitoring device 20 (220). F is detected. Then, based on the behavior of the person F, it is determined whether or not the person F is a suspicious person. For example, if the person F takes actions such as standing in one place for a long time or crouching between the vehicles 5, it is determined that the person F is highly likely to be a suspicious person. In addition, any analysis method for judging a suspicious person may be used.

An analysis of the image is generated (step 304). The analysis results include, for example, the probability that the person F is a suspicious person, the nearest (most aware) parking space 66, and the like. Also, the time during which the person F is photographed, the camera 21, and the like may be generated as an analysis result.

As shown in FIG. 10, the generated analysis result is sent to the parking space monitoring device 20 (220) (step 204) and received by the parking space monitoring device 20 (220) (step 205). At this time, the analysis result is also sent to the parking space monitoring device 20 (220) located in the parking space 66 associated with the person F. This makes it possible to share information on suspicious persons. Further, when a suspicious person is detected, the analysis result is also sent to the management agency terminal 50 shown in FIG. 1 together with the image. As a result, it becomes possible for the operator to quickly make a judgment based on visual recognition, and it is possible to promptly report the situation to the police.

When the parking space monitoring device 20 (220) receives an analysis result indicating that the person is highly likely to be a suspicious person, a predetermined process for crime prevention may be executed. For example, the display unit 22 or the speaker 23 may output that the surveillance system is running, such as "surveillance camera in operation". Alternatively, the periphery of the parking space 66 may be brightly displayed by a lighting device or the like provided in advance. In addition, various security operations are conceivable.

It should be noted that the image analysis is performed in the same manner for the images captured by the surveillance camera 62 arranged near the entry/exit gate 61 . By also using the analysis result, it is possible to accurately detect a suspicious person or the like in the parking lot 15 (215), thus exhibiting a high degree of crime prevention.

Thus, in this parking lot system, surveillance of suspicious persons and the like is executed based on captured images for detecting the entry/exit of the vehicle 5 and the open state of the door. This makes it possible to exhibit a very high degree of security.

For example, it is possible to sufficiently monitor the area between the vehicles 5, which is difficult to photograph with the surveillance camera 62 placed near the entry/exit gate 61, so that a very wide range with few blind spots can be monitored. It is possible to make it a monitoring target range. In particular, as described in the second embodiment, by setting the photographing range obliquely from one end of the rear portion 72 and comprehensively managing the analysis results based on the photographed images of the respective cameras 21, Furthermore, blind spots can be reduced, and an efficient security system can be constructed. In addition, since the other parking spaces 80a to 80c can also be photographed, a suspicious person approaching not only the own parking space 66 but also the other parking spaces 80a to 80c or a suspicious person wandering around the parking lot 15 can be detected with high accuracy. becomes possible. As a result, damage such as vehicle theft can be sufficiently suppressed.

In addition, since the timing of opening the door can be obtained from the detection result of the door opening, it is possible not only to prevent entry and exit of the driver and passengers from the vehicle 5, but also to prevent theft due to the opening of the door of the vehicle 5 forgotten to be locked, and the door to the adjacent vehicle 5. It becomes easy to memorize and extract the timing at which various phenomena related to door opening such as contact with the door occur. As a result, when the content of the image is browsed after the fact, the searchability of the image is improved, and the security is further improved. That is, it becomes possible to search past images and the like centering on the timing at which the door was opened, making it possible to easily discover the various phenomena described above.

FIG. 13 is a flowchart showing an example of notification of guidance information using person detection. The description will focus on the parts that are different from the flow chart of FIG. In the flow shown in FIG. 13, at step 409, it is determined whether or not at least one of the open state of the door and the person F has been detected, and if YES, the settlement method is notified again. (Step 413). This makes it possible for the user of the parking lot 15 (215) to perform another notification before opening the door. Then, when the person F is detected in step 409, it is analyzed whether or not the detected person F is a suspicious person (steps 414, 415, 416).

At step 409, it is determined whether or not both the open state of the door and the person F have been detected, and if YES, notification of the settlement method may be performed again. As a result, it is possible to detect with high accuracy the situation in which the user tries to get on the vehicle while the payment has not been made, and it is possible to notify the user at an appropriate timing. For example, it is assumed that the vehicle 5 traveling slowly on the central road 68 overlaps the parked vehicle 5, increasing the contour area and determining that the door is in the open state. Even in this case, when the person F is not detected, the notification is not performed again. As a result, it becomes possible to prevent the execution of the notification again at an erroneous timing. It is also possible to prevent the notification from being executed again due to the detection of a person trying to get on the front passenger seat of the adjacent vehicle 5 .

Note that the image analysis function illustrated in FIG. 12 may be provided in the parking space monitoring device 20 (220). In this case, the control unit 26 of the parking space monitoring device 20 (220) constitutes a determination unit that determines whether or not the person F detected by the person detection unit 30 is a suspicious person.

<Other embodiments>
The present invention is not limited to the embodiments described above, and can be implemented in various other embodiments.

For example, based on the photographed image photographed by the camera 21 of the parking space monitoring device 20 (220), the closed state of the door of the vehicle 5, the lighting of the brake lamp, and the like may be detected. For example, when the open state of the door is detected in the unpaid state, the notification of the first step is performed again. After that, when it is detected that the door is closed, it is determined that the passenger has just boarded the vehicle, and the notification of the second step is performed again. For example, the color of the alarm is displayed via the display unit or the like, and the volume of the voice output is increased. At this time, non-detection of the person F may be set as an additional condition. After that, when the lighting of the brake lamp is detected, it is determined that the vehicle 5 is about to leave the garage, and the third stage notification is performed again with the volume increased. By such processing, it is possible to sufficiently prevent leaving the parking lot due to non-payment.

In the above, the parking space monitoring device 20 (220) is arranged for each parking space 66, and the camera 21 is provided there. The arrangement of the camera 21 is not limited to this configuration, and the camera 21 may be provided at a position different from the display section 22 and the notification section including the speaker 23 . For example, the camera 21 may be provided separately from the parking space monitoring device 20 (220) at a high place facing the parking space 66. Also, one camera may be capable of photographing a plurality of parking spaces 66 . In other words, monitoring may be performed with a smaller number of cameras 21 than the number of parking spaces 66 (the number of parking space monitoring devices 20 (220)). In this case, for example, the parking space number of the detected object (vehicle 5, person F, etc.) may be recognized according to the position and size of the object obtained from the image.
