Description

  The present invention relates to an object recognition technique for recognizing a communication object having identification information using electromagnetic waves.

  In the past, systems such as entrance / exit control machines and ticket gates that automatically check and control entry / exit for entry / exit at stadiums, amusement parks, movie theaters, railway stations, etc., without using human resources, have developed various technologies. Has been developed using. In recent years, an entrance / exit control system that employs RFID (Radio Frequency Identification) technology and uses a non-contact IC card as an entrance / exit ticket has been put into practical use.

  The technology of this non-contact IC card is standardized in international standards such as ISO / IEC 10536 (contact type), ISO / IEC 14443 (proximity type), ISO / IEC 15693 (neighbor type) and the like. For this reason, the entrance / exit control system using a non-contact IC card is now widely spread along with the flow of card sharing between systems.

  Furthermore, as in the technique described in Patent Document 1, an admission gate device that automatically authenticates the legitimacy of admission using admission ticket information downloaded to a mobile terminal and permits admission according to the authentication result -An information management device has also been devised. Also in the technology of this Patent Document 1, short-distance electromagnetic wave (infrared) communication is performed between the mobile terminal and the entrance gate.

JP 2003-132382 A

  However, in the entrance / exit control system using the conventional non-contact IC card described above, there may be a problem that entrance / exit cannot be processed in a short time.

  Actually, the communicable distances in the non-contact IC card standards ISO / IEC 10536, ISO / IEC 14443, and ISO / IEC 15693 are 1 mm or less, 20 cm or less, and 1 m or less, respectively. That is, at the time of entry / exit, the non-contact IC card and the entrance / exit gate must always carry out such short distance communication. Accordingly, RFID communication can be performed only when an entrance / exit person having a non-contact IC card arrives at the installation position of the entrance / exit gate equipped with a reader / writer.

  Furthermore, the conventional entrance / exit gate communicates RFID with a non-contact IC card and transmits / receives authentication information to / from an information center server, and then recognizes the physical location of the entrance / exit person. The circuit breaker must be opened and closed. That is, a predetermined time is required for passing through the conventional entrance / exit gate. When these circumstances are combined and a considerable number of attendees gather, it becomes difficult to process entrance and exit in a short time, for example, a queue of attendees is created.

  In particular, in various games and events, the attendees often rush to the entrance / exit gate immediately before the start time or immediately after the end time, and the degree of congestion becomes very high. Furthermore, during the rush hour at the railway station, there are many cases where train users who get off line in front of the ticket gates. In such a case, the entry / exit process takes a very long time.

  In this regard, the technique of Patent Document 1 described above also has the same problem of entry / exit processing time as long as infrared communication is used between the mobile terminal and the entrance gate.

  In addition, although not entering or leaving, even when identifying products with electronic tags, as currently used in various distribution fields, these products must approach or arrive at a predetermined inspection position. It is necessary to wait and identify. Therefore, as in the conventional entrance / exit system described above, when a large number of products are identified, a considerable amount of time is required for the processing.

  Therefore, the present invention can recognize a communication target or a recognition target possessing or attached to the communication target in a short time without waiting for the communication target having identification information to approach the predetermined position.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[Object recognition system]
FIG. 1 is a schematic diagram showing an embodiment of an object recognition system according to the present invention.

The object recognition system of the embodiment shown in FIG.
(A) a wireless access point 1 installed above the entrance area at a position where there are no obstacles;
(B) A target management server 2 that manages recognition / identification results of a person (entrant) that is a recognition target in the entrance area and controls correspondence to the person (entrant).

  The target recognition system acquires identification information (entrance ticket information) of the terminal 5 that is a communication target, and recognizes and identifies a visitor (person) possessing the terminal 5. In the present embodiment, a plurality of visitors having the terminal 5 are walking toward the gate 42 provided at the entrance of the venue in an entrance area outside the venue or adjacent to the venue. Here, the terminal 5 can be, for example, a smartphone, a tablet computer, or a mobile phone.

  The wireless access point 1 can be communicably connected to the target management server 2 via a local area network (LAN), the access network 6, or the access network 6 and the Internet 7. The access network 6 is a communication carrier network, and may be a wireless communication network or a fixed line communication network.

Here, the wireless access point 1 first
(A) An electromagnetic wave beam including inquiry information for the terminal 5 is transmitted so as to be moved while the irradiation area by the electromagnetic wave beam is specified in the entrance area.
This electromagnetic wave beam is an electromagnetic wave that is a centimeter wave (3 to 30 GHz), millimeter wave (30 to 300 GHz), or submillimeter wave (300 GHz to 3 THz). In the present embodiment, a millimeter wave band such as 60 GHz defined by the wireless communication standard WiGig (Wireless Gigabit Alliance) is used as the electromagnetic wave. In the 60 GHz band that can be used without permission as a specific low-power radio station, up to four channels with a bandwidth of 2.16 GHz can be used in 57 to 66 GHz. Here, the data transmission rate in one channel reaches, for example, a maximum of 7 Gbps (bits per second), and large capacity transmission is possible. As a result, large-capacity data communication is possible in a very short time between one terminal 5 and the wireless access point 1.

  The electromagnetic waves as described above have high directivity and straightness, can be formed in a beam shape, and can be transmitted toward a narrow irradiation region (for example, a beam spot having a diameter of 0.5 to 5 m). The distance between the wireless access point 1 and the entrance area can be set to 5 to 20 m, for example. Furthermore, a wide area on the line or on the surface (entrance (exit) area in FIG. 1) can be scanned (scanned) at high speed by connecting a plurality of such narrow irradiation areas. At this time, it is possible to limit the area to be scanned and to irradiate the beam only on a desired area. Further, from these characteristics, in communication using such an electromagnetic wave beam, higher secrecy is ensured as compared with, for example, Wi-Fi (registered trademark).

  Here, the electromagnetic wave beam can be directed in an arbitrary direction, that is, beam-steered using a phased array antenna. Of course, it is also possible to scan the electromagnetic wave beam by mechanically changing the direction of the transmitting antenna. Further, the beam half-width can be arbitrarily set within a range of, for example, 3 to 20 degrees (degrees) by adjusting the configuration of the two-dimensional antenna.

  The characteristics of the electromagnetic wave beam described above are peculiar to the electromagnetic wave beam that cannot be realized by radio waves used for Wi-Fi (registered trademark) and mobile phone communication, for example. Actually, the radio wave of Wi-Fi (registered trademark) and mobile phone communication has the property of spreading widely, so it is very difficult to irradiate this radio wave to individual terminals located within a predetermined area because the antenna shape is very It becomes unrealistic because it gets bigger. Furthermore, since the communication speed is relatively low and the number of channels is limited, it is difficult to communicate with a large number of visitors located within a predetermined area in a short time.

  Further, the entrance area can be divided into n × m (for example, 5 × 10) sections defined by the irradiation region (beam spot). The electromagnetic wave beam sequentially scans these sections (beam spots), and the path or scanning pattern can take various forms such as a raster scan, a zigzag (one-stroke), a random scan.

As a form other than the embodiment for moving (scanning) the electromagnetic wave beam described above, the wireless access point 1 is:
(A ′) It is also possible to transmit a plurality of electromagnetic wave beams including inquiry information for the terminal 5 by specifying and fixing respective irradiation areas by these electromagnetic wave beams in the entrance area. For example, a plurality of antennas may be arranged in a grid pattern above the entrance area, and each antenna may be irradiated with an electromagnetic wave beam fixed in a one-to-one correspondence with each beam spot (irradiation area). it can. In this case, it is possible to communicate with, for example, the terminals 5 distributed over the entire entrance area at a time by irradiating a plurality of electromagnetic wave beams at once. It becomes possible.

Next, the wireless access point 1
(A) A response wave including admission ticket information (identification information), which is an admission identifier, is transmitted from the terminal 5 that has received the electromagnetic wave beam.
Here, the terminal 5 includes a millimeter-wave band compatible electronic tag 50 provided with admission ticket information (identification information), and further includes an application for activating the electronic tag 50. The electronic tag 50 can be a semi-active tag (battery assist / passive tab) or an active tab. When an electromagnetic wave beam including predetermined inquiry information is received, a response wave including admission ticket information (identification information) is transmitted. . A visitor activates an application for entry when entering the entrance area or in advance.

  The electronic tag 50 can be a passive tab. In this case, the electronic tag 50 is powered by the received electromagnetic wave beam, processes inquiry information included in the beam, and then transmits a response wave including admission ticket information (identification information). Therefore, the electronic tag 50 itself does not require a battery. However, in this case, since the response wave to be transmitted is weak in intensity, the reception unit of the wireless access point 1 has a correspondingly high reception sensitivity.

  As another embodiment, the terminal 5 is a mobile wireless terminal capable of transmitting and receiving millimeter wave electromagnetic waves, for example, and is equipped with an application for transmitting a response wave corresponding to inquiry information of the received electromagnetic wave beam It may be.

  Furthermore, the response wave may be an electromagnetic wave in a frequency band other than the millimeter wave band as defined by WiGig. For example, a response from a communication interface for mobile phone communication such as Wi-Fi (registered trademark), WiMAX (Worldwide Interoperability for Microwave Access), or LTE (Long Term Evolution) or 3G (3rd Generation) of the terminal 5 It is also possible to transmit waves. In this case, the receiving unit of the wireless access point 1 may be provided with a communication interface of a corresponding communication method, or the target management server 2 is transmitted from the terminal 5 via the corresponding communication carrier network. Response wave signal information may be acquired.

Next, the target management server 2 receives response wave information from the wireless access point 1 that has received the response wave,
(C) The position of the terminal 5 that transmitted the response wave is specified based on the transmission time information of the electromagnetic wave beam that caused the transmission of the received response wave or the position information of the irradiation area (beam spot).
Here, when the electromagnetic wave beam is scanned, the position of the terminal 5 as the communication destination can be specified as the position of the irradiation region (beam spot) by controlling and grasping the directivity angle of the beam.

The target management server 2 further
(D) For each admission ticket information (identification information) that is an admission identifier acquired from the received response wave, the specified position of the terminal 5 having the admission ticket information (identification information) is stored in association with each other.
That is, when the electromagnetic wave beam is scanned at high speed in the entrance area, the target management server 2 can grasp the momentary position of the terminal 5 (the attendee who possesses it) corresponding to the entrance ticket information (identification information). It can be done.

  Incidentally, the admission ticket information (identification information) can be preliminarily purchased from a trader and stored in the terminal 5 by the user (entrant). This admission ticket information includes an admission ID, and the merchant may record the admission ID in association with user information in an ID storage unit 201 (installed in the target management server 2) described later. preferable. In this case, the target management server 2 can verify the admission permission by comparing the admission ID included in the admission ticket information acquired from the response wave with the recorded admission ID.

  As described above, the target recognition system performs communication with the terminal (communication target) 5 using an electromagnetic wave beam having a high transmission rate in which the irradiation area is controlled. As a result, without waiting for the terminal (communication target) 5 having the admission ticket information (identification information) to approach the predetermined position, the visitor (the recognition target) possessing the terminal (communication target) 5 or the terminal 5 in a short time. ) Can be recognized.

Furthermore, the target management server 2 sends the wireless access point 1
(E) The notification information previously associated with the admission ticket information (identification information) which is the admission identifier of the terminal 5 is included at the timing of irradiating the specified position toward the specified terminal 5 It is also preferable to emit an electromagnetic wave beam. Here, the notification information is information related to admission, for example, an authentication result indicating admission or route guidance after admission. A visitor who has the terminal 5 that has received the authentication result of admission can enter, for example, beyond the admission line. The provision of such notification information will be described in detail later with reference to FIG.

  Thus, in this embodiment, a visitor can receive the admission permission authentication, for example, walking. Furthermore, it is possible to manage and control a person who is going to enter without using a conventional entrance gate that may cause congestion when a large number of visitors rush. As a result, a large number of legitimate visitors can enter in a short time and smoothly.

  Of course, the recognition target is not limited to visitors. It is also possible to make a person who is in the venue or in an exit area adjacent to the venue a subject of recognition, and as described with reference to FIG. 6, an electronic tag (communication subject) 50 ′ is attached. Goods such as an automobile 5 ′, or a living organism such as livestock with an electronic tag attached thereto may be used.

The device control unit 111 controls the shooting operation of the shooting unit 30, inputs a captured image (moving image or still image) signal from the shooting unit 30 via the device interface 102, and passes the communication interface 101. It is transmitted to the target management server 2. In addition, an operation instruction signal is received from the target management server 2 via the communication interface 101, and the speaker 40, the projector 41, or the gate 42 is operated and controlled based on the operation instruction signal.

Also, the provided information storage unit 202 stores notification information provided to the terminal 5 (person who owns it (entrant)) in association with admission ticket information (identification information) as an entrance identifier.

The target specifying unit 210 specifies the position of the communication target that has transmitted the response wave based on the transmission time information of the electromagnetic wave beam that has caused the transmission of the received response wave or the position information of the irradiation region (beam spot). As another embodiment, a person who is a recognition target (entrance) that does not transmit a response wave by using a photographing unit 30 such as a camera capable of photographing an area where at least one communication target exists (entrance area in FIG. 1).

At this time, a response wave from the terminal 5 is received at the irradiation region (beam spot) position, and an electromagnetic wave beam including notification information can be further transmitted toward the terminal 5 at the position. That is, the electromagnetic wave beam uses an electromagnetic wave such as a millimeter wave band, and a transmission speed of the order of, for example, Gbps can be realized. Therefore, the wireless access point 1 can communicate with a large number of terminals 5 in the entrance area at high speed in spot units, and can authenticate the admission permission and can instantly notify the authentication result as notification information. .

  In other words, with such an electromagnetic wave beam, it is possible to scan a single beam spot in the order of 1 millisecond (ms) or less. This time is a time when it is hardly recognized that the person has moved based on the walking speed. Therefore, the terminal 5 whose position is specified can receive the notification information at substantially the same position.

  In addition, as a change mode, after the electromagnetic wave beam is transmitted toward the terminal 5, the notification information is sent at the timing when the entrance area is scanned and then transmitted again toward the position of the terminal 5 after or after that. The included electromagnetic wave beam may be transmitted toward the terminal 5.

  Similarly, according to FIG. 2, the notification information received by the terminal 5 is displayed on the display unit such as a display of the terminal 5 as information related to admission. Information related to this admission includes, for example, notice of admission permission, route guidance after admission, guidance to vacant admission gates, materials related to exhibits in the venue, the procedure for changing the type (class) of admission tickets, and the like Other event guides are listed. Here, the electromagnetic wave beam uses an electromagnetic wave of a millimeter wave band or the like, and realizes a transmission speed of the order of Gbps, for example. As a result, transmission (distribution) of large-capacity or rich content such as explanatory moving images related to exhibits etc. is possible even in a short time when the terminal 5 is irradiated with an electromagnetic wave beam.

  Further, when the admission ticket information (identification information) acquired from the terminal 5 has a plurality of types, for example, the class (grade) of the seating area, it is associated in advance with the type of admission ticket information. It is also preferable to emit an electromagnetic wave beam including the notified information. For example, according to the type (class) of admission ticket information, information for guiding different routes after admission can be transmitted to the terminal 5 and displayed.

  Furthermore, even if the visitor has a plurality of types of electronic tag tickets that are different from each other in a form built in the terminal 5 or owned by the terminal 5, the target recognition system uses the terminal 5 or these electronic tag tickets. It is also possible to analyze the transmitted response wave, select only the identification information of the electronic tag / ticket to be entered, perform authentication, and transmit the corresponding notification information to the terminal 5.

  Further, the notification information may be a sound (for example, voice guidance) related to the entrance generated from a speaker built in the terminal 5. Further, as the notification information, a vibrator mounted on the terminal 5 can be driven, or a predetermined light emitting unit can be caused to emit light.

  Furthermore, the notification information does not have admission ticket information for a terminal 5 that has transmitted a response wave but does not include admission ticket information (identification information) in the response wave, and has received a result that the admission authentication is not possible. It may be provided by displaying a warning to that, or an admission ticket (information) acquisition, an inquiry to the (purchasing admission ticket) window or a recommendation to leave. Or it may be provided by generating a sound for warnings or recommendations. Further, as a modification, the target recognition system uses a purchase request from the terminal 5 as a response wave so that an admission applicant who does not have admission ticket information can purchase an admission ticket (information) in the admission area. It is also preferable to transmit an electromagnetic wave beam including the received and issued admission ticket information to the terminal 5.

[Pass control based on the position of the terminal 5]
FIG. 3 is a schematic diagram for explaining an embodiment for controlling the passage control device based on the position of the communication object in the object recognition system of the present invention.

  According to FIG. 3, first, the electromagnetic wave beam is repeatedly scanned within a predetermined entrance area (scanning area). Here, every time an electromagnetic wave beam that moves momentarily irradiates the terminal 5 (the attendee who owns it), a response wave including admission ticket information (identification information) is received from the terminal 5.

  Next, the target recognition system is configured such that the terminal 5 is based on the momentary position of the terminal 5 specified every time a response wave is received from the terminal 5 having predetermined (regular) admission ticket information (identification information). It is determined whether or not a predetermined position has been approached or reached. In the present embodiment, this predetermined position is the installation position of the gate 42 which is a passage control device. In addition, the visitors move on foot within the entrance area and are heading toward the gate 42 to enter.

  Here, the beam spots (irradiation regions) responsible for specifying the position of the terminal 5 may be separated without being overlapped, but it is also preferable that they have overlapping portions. When the beam spots are superimposed on each other in this manner, depending on the position of the terminal 5, the terminal 5 responds to each electromagnetic wave beam corresponding to each beam spot position. As a result, the accuracy of specifying the position of the terminal 5 is improved. For example, when the beam spots overlap each other by about the spot radius, the position specifying accuracy increases to the order of the spot radius. Furthermore, it is possible to obtain higher position specifying accuracy by more closely superimposing the beam spots. As described above, as a method for improving the position specifying accuracy of the terminal 5, it is also effective to superimpose beam spots in addition to reducing the beam spot diameter. In particular, when there are physical conditions (such as the ceiling where the wireless access point 1 should be installed is at a high position, there is a limit to narrowing the electromagnetic wave depending on the antenna shape) where the beam spot diameter cannot be reduced, the beam spots are superimposed. This method is preferable.

  Note that “approaching” when determining whether or not the terminal 5 has approached or arrived at a predetermined position means, for example, that the distance between the terminal 5 and the predetermined position (passage control device) is the above position. It may be defined as a value of a specific accuracy, or a situation that is a constant multiple thereof.

  Here, when it is determined that the terminal 5 (the visitor who owns the terminal 5) has approached or reached the installation position of the gate 42, the target control unit 214 passes the visitor who owns the terminal 5 with respect to the gate 42. Instruct them to do so. Specifically, for example, an instruction is given to leave the gate (or breaker) of the passage formed by the gate 42 as it is, and to open it when the gate (or breaker) is closed.

  Note that the terminal 5 that transmits the response wave but does not include the predetermined (regular) admission ticket information (identification information) in the response wave is similar to the method described above. It is possible to grasp the position every moment. In this case, when it is determined that the terminal 5 (the person who owns the terminal 5) has approached or reached the installation position of the gate 42, the target control unit 214 does not pass the person who owns the terminal 5 to the gate 42. To instruct. Specifically, for example, when the gate (or circuit breaker) of the passage formed by the gate 42 is closed, it is left as it is, and when this gate (or circuit breaker) is opened, an instruction is given to close it.

  Thus, the gate 42 only performs an opening / closing operation in accordance with an operation instruction from the target control unit 214, and there is no need to acquire information such as an entrance ID from the target management server 2 and perform authentication. Also, there is no need to exchange admission ticket information with the visitors waiting for the visitors to approach. As a result, the operation processing time at the gate 42 is short, and a legitimate visitor can smoothly pass through the gate 42 at a normal walking speed, for example.

[Caution information]
FIG. 4 is a schematic diagram for explaining an embodiment in which a recognition target that does not transmit a response wave is specified using the imaging unit 30 in the target recognition system of the present invention.

According to FIG. 4, the electromagnetic wave beam transmitted from the wireless access point 1 scans the entrance area. In addition, the imaging unit 30 that is a camera or the like is imaging an area where the at least one terminal (communication target) 5 exists (an area including an entrance area in this embodiment). Thereby, for example, every time the electromagnetic wave beam scans through the entrance area,
(A) Based on the response wave to the electromagnetic wave beam, the position information of the terminal (communication target) 5 whose position is specified;
(B) The information of the image including the person (recognition target) possessing the terminal (communication target) 5 generated by the photographing unit 30 is acquired.

  The target specifying unit 210 specifies a visitor (recognition target) that does not transmit a response wave based on the communication target position information (a) and the image information (b). Specifically, among the person images included in the image information (b), a person image in which a terminal (which has transmitted a response wave) is not detected at a corresponding position in the communication target position information (a) It is specified as a visitor (recognition target) who does not transmit a response wave. Here, a one-to-one correspondence is set in advance between the position coordinates of the communication target position information (a) and the position coordinates of the image information (b). In addition, recognition of a person image can be performed using a conventional person recognition technology as disclosed in, for example, Japanese Patent Application Laid-Open No. 2011-248525.

  Next, the caution information providing unit 213 provides caution information corresponding to not transmitting the response wave toward the position specified from the image information (b) in the person (recognition target) that does not transmit the response wave. For example, as this caution information, a person who does not have a terminal having admission ticket information (identification information) (a person who does not transmit a response wave, and a person who transmits a response wave that does not include admission ticket information (identification information)) ) To spot light using the projector 41.

  Further, the reporting unit 215 notifies the security guard, who is the main security officer, of the location information of the person who is not supposed to have a terminal having admission ticket information (identification information). In this case, for example, it is possible to display the position information of the person on a mobile terminal possessed by a security guard via a wireless network and sound an alarm in the mobile terminal.

[Pass control using captured images]

Thus, the position of the person (recognition target) who does not transmit the response wave is specified. Specifically, among the human images included in the image information (b) obtained every moment, the terminal (which has transmitted a response wave) at the corresponding position in the communication target position information (a) at the corresponding time. A person image that has not been detected is recognized as a person (recognition target) that does not transmit a response wave, and its position is specified every moment.

  Next, the target control unit 214 determines whether or not the person has approached or reached a predetermined position based on the specified momentary position in a person (recognition target) that does not transmit a response wave. In the present embodiment, this predetermined position is the installation position of the gate 42 which is a passage control device. In addition, along with visitors having admission ticket information, unauthorized visitors who have not acquired admission ticket information also move on foot to the gate 42 within the admission area.

  Here, when it is determined that a person (recognition target) that does not transmit a response wave has approached or reached the installation position of the gate 42, the target control unit 214 instructs the gate 42 not to pass the person. . Specifically, for example, when the gate (or circuit breaker) of the passage formed by the gate 42 is closed, it is left as it is, and when this gate (or circuit breaker) is opened, an instruction is given to close it.

As described with reference to FIG. 3, the response wave is transmitted to the terminal 5 (who owns the response wave but does not include predetermined (regular) admission ticket information (identification information). It is possible to control so that the gate 42 does not pass through. Thereby, a person who does not have a terminal having admission ticket information (identification information), that is,
(A) A person who does not transmit a predetermined (regular) response wave (including the owner of a terminal that has not started a predetermined application), and (b) a response wave that does not include admission ticket information (identification information) It is possible to deal with a person so as not to make unauthorized entry.
