[0004] The technology of Patent Document 1 makes it possible to control the environment inside the vehicle by remote control, but if an occupant is in a critical condition, controlling the environment inside the vehicle alone is not enough to provide adequate relief to the occupant. In such a case where a crew member is in a serious condition, it is desirable to quickly dispatch rescue personnel and provide rescue to the crew member. In order to dispatch rescue personnel, the vehicle's location must be identified. However, when the vehicle is parked in a large parking lot with many parking spaces, it is difficult to quickly identify the parking space in which the vehicle is parked.

[0005] In view of the above circumstances, the main objective of the present disclosure is to quickly identify the parking space in which a vehicle is parked in a parking lot that includes multiple parking spaces. [Means for solving the problem]

[0009] Hereinafter, the embodiments will be described with reference to the drawings. In the following description of the embodiments and in the drawings, the same reference numerals denote the same or corresponding parts.

[0010] Embodiment 1 ***Configuration Description*** FIG. 1 shows an example of the configuration of a parking lot management system 800 according to this embodiment.

[0011] In the parking lot management system 800, a parking lot 200 is provided with a plurality of parking spaces 201. Each parking section 201 is a space for parking a vehicle 500. In addition, each parking space 201 is provided with a car stopper 202.

[0012] A camera 300 is provided for each parking section 201. That is, in this embodiment, there is a one-to-one correspondence between the parking sections 201 and the cameras 300. However, for example, one camera 300 may be provided for two parking sections 201, or one camera 300 may be provided for three parking sections 201.

[0013] The camera 300 has a photographing function, an object recognition function, and a transmission function. Furthermore, the camera 300 stores a camera ID (Identifier) ​​that is an identifier for the camera 300. The camera 300 recognizes that the vehicle 500 has entered the parking space 201. The camera 300 captures an image of the vehicle 500 parked in the parking space 201. The camera 300 then transmits the captured image and the camera ID to the information processing device 100 via the communication network 600. Furthermore, the camera 300 recognizes that the vehicle 500 has exited the parking space 201. Then, the camera 300 transmits the camera ID as exit information to the information processing device 100 via the communication network 600. 1, for convenience of illustration, the connection between the cameras 300 and the communication network 600 shown in the upper part of FIG. 1 is omitted, but it is assumed that each camera 300 is connected to the communication network 600.

[0014] The vehicle 500 is equipped with a vital sensor. The vital sensor collects biological information of the occupant seated in the seat. The biological information is information that is an indicator of the occupant's health condition. The biological information includes information on pulse, respiration, body temperature, blood pressure, etc. The vehicle 500 is also equipped with a health condition determining device and wireless communication equipment. The physical condition determination device analyzes the biological information collected by the vital sensor and determines the condition of the occupant. When it is determined that the occupant is in a state requiring rescue, the physical condition determination device transmits notification information notifying the biological information and the number plate value of the vehicle 500 to the information processing device 100 using a wireless communication device.

[0015] A plurality of cameras 300, an information processing device 100, and a rescue communication device 700 are connected to the communication network 600. The communication network 600 realizes communication between each camera 300 and the information processing device 100 . Moreover, the communication network 600 realizes communication between the information processing device 100 and the rescue communication device 700 .

[0016] The information processing device 100 receives the captured image and the camera ID transmitted from the camera 300. Furthermore, when notification information is transmitted from the vehicle 500, the information processing device 100 receives the notification information. Then, the information processing device 100 identifies the parking section 201 in which the vehicle 500 that is the source of the notification information is parked. Furthermore, the information processing device 100 transmits to the rescue communication device 700 notification information that notifies the identified parking space 201 and the biological information notified in the notification information.

[0017] The rescue communication device 700 is a communication device used in a rescue facility. A relief facility is a facility that dispatches rescue personnel. The relief facility is a relief department of a company that operates parking lot 200, a medical institution, a fire station, etc.

[0018] FIG. 2 shows an example of a hardware configuration of the information processing device 100 according to the present embodiment. FIG. 3 shows an example of a functional configuration of the information processing device 100 according to the present embodiment. Information processing device 100 according to this embodiment is a computer. The operation procedure of information processing device 100 corresponds to an information processing method. Moreover, a program that realizes the operation of information processing device 100 corresponds to an information processing program.

[0019] As shown in FIG. 2, the information processing device 100 includes, as hardware, a processor 901, a main storage device 902, an auxiliary storage device 903, and a communication device 904. As shown in FIG. 3, the information processing device 100 has, as its functional configuration, a captured image acquisition unit 101, a license plate identification unit 102, a parking space identification unit 103, a notification information receiving unit 105, a parking space identification unit 106, an alarm information generation unit 107, an alarm information transmission unit 108, a message generation unit 109, a message output unit 110, and an information storage unit 111.

[0020] The functions of the captured image acquisition unit 101, the license plate identification unit 102, the parking space identification unit 103, the notification information receiving unit 105, the parking space identification unit 106, the notification information generation unit 107, the notification information transmission unit 108, the message generation unit 109 and the message output unit 110 are realized, for example, by a program. The auxiliary memory device 903 stores programs that realize the functions of the captured image acquisition unit 101, the license plate identification unit 102, the parking space identification unit 103, the notification information receiving unit 105, the parking space identification unit 106, the notification information generation unit 107, the notification information transmission unit 108, the message generation unit 109 and the message output unit 110. These programs are loaded from the auxiliary storage device 903 to the main storage device 902. Then, the processor 901 executes these programs to perform operations of a photographed image acquisition unit 101, a license plate identification unit 102, a parking space identification unit 103, a notification information receiving unit 105, a parking space identification unit 106, a notification information generation unit 107, a notification information transmission unit 108, a message generation unit 109, and a message output unit 110, which will be described later. Figure 2 shows a schematic representation of the state in which the processor 901 is executing programs that realize the functions of the captured image acquisition unit 101, the license plate identification unit 102, the parking space identification unit 103, the notification information receiving unit 105, the parking space identification unit 106, the notification information generation unit 107, the notification information transmission unit 108, the message generation unit 109 and the message output unit 110. The information storage unit 111 is realized by, for example, the auxiliary storage device 902 . The communication device 904 supports both wired communication with the communication network 600 and wireless communication with the vehicle 500 .

[0021] Next, an example of the functional configuration of the information processing device 100 will be described with reference to FIG.

[0022] The captured image acquisition unit 101 receives a captured image and a camera ID from the camera 300 . In addition, the captured image acquisition unit 101 outputs the captured image to the license plate identification unit 102 and outputs the camera ID to the parking space identification unit 103.

[0023] FIG. 4 shows an example of a captured image received by the captured image acquisition unit 101. As shown in FIG. The captured image includes an image of a vehicle 500 parked in a parking space 201. The image of the vehicle 500 includes an image of a license plate 501.

[0024] The license plate identification unit 102 analyzes the captured image output from the captured image acquisition unit 101, and identifies the value of the license plate 501 shown in the captured image as an identified license plate value. The license plate identification unit 102 then outputs the identified license plate value to the association unit 104 . The process performed by the license plate identification unit 102 corresponds to a license plate identification process.

[0025] Based on the camera ID output from the captured image acquisition unit 101 and the camera section information 112, the parking section identification unit 103 identifies the parking section 201 in which the vehicle 500 shown in the captured image is parked as an identified parking section. Then, the parking section identification unit 103 outputs the identified parking section to the association unit 104. The processing performed by the parking section identification unit 103 corresponds to a parking section identification processing.

[0026] The matching unit 104 generates matching information 113 by matching the identified license plate value output from the license plate identification unit 102 with the identified parking space output from the parking space identification unit 103 for each vehicle 500 parked in the parking lot 200. Then, association unit 104 stores generated association information 113 in information storage unit 111 . The process performed by association unit 104 corresponds to association processing.

[0027] The notification information receiving unit 105 receives the notification information transmitted from the vehicle 500 . Then, the notification information receiving unit 105 outputs the license plate number included in the notification information (hereinafter, referred to as a notified license plate number) to the parking section identifying unit 106. Furthermore, the notification information receiving unit 105 outputs the biological information included in the notification information to the notification information generating unit 107 . The process performed by the notification information receiving unit 105 corresponds to a notification information receiving process.

[0028] The parking space identification unit 106 compares the notified license plate value with the identified license plate value indicated in the correspondence information 113, and identifies the parking space in which the vehicle 500 that sent the notified information is parked as a specific parking space. The parking space identifying unit 106 outputs the identified parking space to the notification information generating unit 107 and the message generating unit 109 . The processing performed by the parking section identification unit 106 corresponds to a parking section identification processing.

[0029] The notification information generating unit 107 generates notification information using the biological information output from the notification information receiving unit 105 and the identified parking space output from the parking space identifying unit 106 . The notification information is information that notifies a first aid facility of the biometric information and the specific parking space. The broadcast information generating unit 107 outputs the generated broadcast information to the broadcast information transmitting unit 108 .

[0030] The notification information transmitting unit 108 transmits the notification information output from the notification information generating unit 107 to the rescue communication device 700 .

[0031] A message generating unit 109 generates a voice message requesting that rescue be directed to a specific parking space. The message generating unit 109 outputs the generated voice message to the message output unit 110 .

[0032] The message output unit 110 outputs the voice message generated by the message generation unit 109 from a speaker installed in the parking lot 200, for example.

[0033] The information storage unit 111 stores camera section information 112 and association information 113 . The camera section information 112 is information that associates a camera ID with a parking section 201. The association information 113 is information generated by the association unit 104 that associates the identified license plate value with the identified parking space.

[0034] FIG. 5 shows an example of the camera section information 112. As described above, in this embodiment, there is a one-to-one correspondence between the cameras 300 and the parking sections 201. Therefore, the camera section information 112 also has a one-to-one correspondence between the camera ID and the parking section. When one camera 300 is provided for two parking spaces 201, camera space information 112 is prepared for each camera ID, which defines the parking space 201 appearing on the right side of the captured image and the parking space 201 appearing on the left side of the captured image. In addition, when one camera 300 is provided for three parking spaces 201, camera space information 112 is prepared for each camera ID, which defines the parking space 201 that appears on the right side of the captured image, the parking space 201 that appears in the center, and the parking space 201 that appears on the left side.

[0035] FIG. 6 shows an example of the association information 113. In the association information 113, the identified license plate value is associated with the identified parking space.

[0036] ***Explanation of Operation*** Next, an example of the operation of the information processing device 100 according to the present embodiment will be described with reference to FIGS. FIG. 7 shows an example of the operation of the information processing device 100 when the vehicle 500 is parked in the parking space 201. FIG. 8 shows an example of the operation of the information processing device 100 when notification information is transmitted from the vehicle 500. FIG. 9 shows an example of the operation of the information processing device 100 when the vehicle 500 exits the parking space 201.

[0037] In FIG. 7, when the captured image acquisition unit 101 receives the captured image and the camera ID transmitted from the camera 300 via the communication device 904 (YES in step S11), the process proceeds to step S12. The captured image acquisition unit 101 outputs the captured image to the license plate identification unit 102 and outputs the camera ID to the parking space identification unit 103.

[0038] In step S12, the license plate identification unit 102 analyzes the captured image output from the captured image acquisition unit 101, and identifies the value of the license plate 501 shown in the captured image as an identified license plate value. The license plate identification unit 102 identifies the license plate value by using an existing character recognition technology. The license plate identification unit 102 outputs the identified license plate value to the association unit 104 .

[0039] Next, in step S13, the parking section identification unit 103 identifies the parking section 201 in which the vehicle 500 shown in the captured image is parked as an identified parking section, based on the camera ID output from the captured image acquisition unit 101 and the camera section information 112. Specifically, the parking section identification unit 103 identifies the parking section 201 associated with the camera ID output from the captured image acquisition unit 101 in the camera section information 112 as an identified parking section. In this manner, the parking space identification unit 103 identifies the parking space by specifying the camera 300 that has transmitted the captured image using the camera ID. The parking space identification unit 103 outputs the identified parking space to the association unit 104 .

[0040] Next, in step S14, the association unit 104 generates association information 113 by associating the identified license plate value output from the license plate identification unit 102 with the identified parking space output from the parking space identification unit 103.

[0041] Then, in step S 15 , association section 104 stores generated association information 113 in information storage section 111 .

[0042] In FIG. 8, when the notification information receiving unit 105 receives the notification information transmitted from the vehicle 500 via the communication device 904 (YES in step S21), the process proceeds to step S22. The notification information receiving unit 105 outputs the notification license plate number included in the notification information to the parking space identifying unit 106. Furthermore, the notification information receiving unit 105 outputs the biological information included in the notification information to the notification information generating unit 107 .

[0043] In step S22, the parking section identification unit 106 identifies the parking section in which the vehicle 500 that is the sender of the notification information is parked as a specific parking section, using the notified license plate value and the association information 113. Specifically, the parking section identification unit 103 identifies the parking section 201 that is associated with the notified license plate value in the association information 113 as a specific parking section. The parking space identifying unit 106 outputs the identified parking space to the notification information generating unit 107 and the message generating unit 109 .

[0044] Next, in step S23, the notification information generating unit 107 generates notification information using the biometric information output from the notification information receiving unit 105 and the identified parking space output from the parking space identifying unit 106. As described above, the notification information is information that notifies the first aid facility of the biometric information and the specific parking space. The broadcast information generating unit 107 outputs the generated broadcast information to the broadcast information transmitting unit 108 .

[0045] Next, in step S24, the notification information transmitting unit 108 transmits the notification information output from the notification information generating unit 107 to the rescue communication device 700 via the communication device 904.

[0046] At the first aid facility, the first aid communication device 700 receives the notification information and displays, for example, the biometric information and the specific parking space on a display. This allows the rescuer to know the current condition of the occupant who needs rescue and to properly prepare the tools and the like required for rescue before heading to rescue the occupant. In addition, the rescuer can accurately know the current location of the occupant (parking space of the vehicle 500).

[0047] Also, in step S25, the message generating unit 109 generates a voice message requesting that rescue be directed to the specific parking space. The message generating unit 109 outputs the generated voice message to the message output unit 110 .

[0048] Next, in step S26, the message output unit 110 outputs the voice message generated by the message generation unit 109 from a speaker installed in the parking lot 200, for example.

[0049] A supervisor at the parking lot 200 hears the voice message and can go to the specific parking space notified by the voice message to provide assistance.

[0050] In Fig. 8, the generation and output of the voice message is performed after the generation and transmission of the notification information, but the generation and output of the voice message may be performed first. Also, the generation and transmission of the notification information and the generation and output of the voice message may be performed in parallel.

[0051] In FIG. 9, when the photographed image acquisition unit 101 receives the exit information (camera ID) transmitted from the camera 300 via the communication device 904 (YES in step S31), the process proceeds to step S32. The captured image acquisition unit 101 outputs the exit information (camera ID) to the parking space identification unit 103 .

[0052] In step S32, the parking section identification unit 103 identifies the parking section 201 from which the vehicle 500 has exited, based on the exit information (camera ID) output from the captured image acquisition unit 101 and the camera section information 112. Specifically, the parking section identification unit 103 identifies the parking section 201 associated with the exit information (camera ID) in the camera section information 112 as the exit parking section. The parking space identification unit 103 outputs the identified exit parking space to the association unit 104 .

[0053] Next, in step S33, the association unit 104 deletes the association information 113 in which the exit parking space output from the parking space identification unit 103 is described from the information storage unit 111.

[0054] ***Description of the Effects of the Embodiment*** In this embodiment, when an occupant of a vehicle parked in any parking space becomes ill, the parking space in which the vehicle is parked is quickly identified. The identified parking space is then notified to a first aid facility. Therefore, according to this embodiment, even in a large parking lot, a first aid worker can be quickly dispatched to the ill occupant.

[0055] Furthermore, in this embodiment, the vital signs are notified to a first aid facility, so that the necessary equipment and other necessary items can be prepared appropriately before heading out to provide aid.

[0056] Furthermore, in this embodiment, a voice message is output requesting that rescue be directed to the identified parking space, so that a parking lot attendant can quickly head to the identified parking space to provide rescue.

[0057] Embodiment 2 In the first embodiment, the parking section identification unit 103 identifies the identified parking section based on the camera ID of the camera 300 that transmitted the captured image. Alternatively, the parking space identification unit 103 may identify the identified parking space by analyzing the captured image. In this embodiment, differences from the first embodiment will be mainly described. It should be noted that matters not explained below are the same as those in the first embodiment.

[0058] FIG. 10 shows an example of a functional configuration of an information processing device 100 according to the present embodiment.

[0059] In FIG. 10, the camera section information 112 is omitted compared to FIG. Moreover, the photographed image acquiring unit 101 receives only the photographed image from the camera 300. Moreover, the photographed image acquiring unit 101 only outputs the photographed image to the license plate identification unit . In addition, the license plate identification unit 102 outputs the captured image to the parking space identification unit 103. The parking space identification unit 103 identifies a parking space based on the captured image.

[0060] FIG. 11 shows an example of an image captured by camera 300 according to the present embodiment. In this embodiment, parking space numbers are provided on the car stop 202. The image captured by the camera 300 also includes an image of the parking space number on the car stop 202.

[0061] In this embodiment, when the camera 300 recognizes that the vehicle 500 is parked in the parking space 201, the camera 300 transmits only the captured image to the information processing device 100.

[0062] The captured image acquisition unit 101 outputs the captured image to the license plate identification unit 102 . The license plate identification unit 102 identifies the identified license plate value and outputs the captured image to the parking space identification unit 103.

[0063] The parking space identification unit 103 analyzes the image of the car stop 202 in the captured image, and identifies the parking space number shown on the car stop 202 as an identified parking space. The parking space identification unit 103 identifies the parking space number by using an existing character recognition technology. Then, the parking section identification unit 103 outputs the identified parking section thus identified to the association unit 104.

[0064] The association unit 104 generates the association data by associating the identified license plate value with the identified parking space in the same manner as in the first embodiment.

[0065] In addition, in this embodiment, when the camera 300 recognizes that the vehicle 500 has left the parking space 201, the camera 300 transmits the captured image to the information processing device 100 as exit information.

[0066] The captured image acquiring unit 101 outputs the captured image to the parking space identifying unit 103 as exit information.

[0067] The parking section identification unit 103 analyzes the image of the car stop 202 in the captured image, and identifies the number of the parking section indicated on the car stop 202 as the exit parking section. Then, the parking section identification unit 103 outputs the exit parking section to the association unit 104.

[0068] The association unit 104 deletes the association information 113 in which the exit parking space output from the parking space identification unit 103 is described from the information storage unit 111, as in the first embodiment.

[0069] The operations of the other components of the information processing device 100 are similar to those described in the first embodiment, and therefore will not be described.

[0070] In this way, according to this embodiment, the parking space in which the vehicle is parked can be identified based on the analysis of the image captured by the camera.

[0071] In the present embodiment, an example has been described in which the license plate identification unit 102 identifies the value of the license plate from the captured image, and the parking space identification unit 103 identifies the parking space from the captured image. Alternatively, the license plate identification unit 102 may identify the license plate number and the parking space from the captured image. In this case, the parking space identification unit 103 can be omitted. Alternatively, the parking section identification unit 103 may identify the value of the license plate and the parking section from the captured image. In this case, the license plate identification unit 102 can be omitted.

[0072] As described above, Embodiments 1 and 2 have been explained, but these two embodiments may be implemented in combination. Alternatively, one of these two embodiments may be partially implemented. Alternatively, these two embodiments may be partially combined and implemented. Also, the configurations and procedures described in these two embodiments may be changed as necessary.
