The present invention relates to a passenger management apparatus and a passenger management method, and more particularly, to a passenger management apparatus and a passenger management method for managing passengers of a transportation means (e.g., a bus) which can transport a large number of people.
In cases where a large number of people travel around a sightseeing course together, a bus is often used. In the case of long-distance travel by bus, a rest is sometimes taken at a spot where there are toilets such as a service area. And a free time during which passengers can act freely at a popular tourist site and the like is sometimes scheduled.
When a rest period or a free time is taken, a bus tour conductor informs passengers of a departure time, and the passengers need return to the bus by the time. At the departure time, the tour conductor checks a return state of the passengers, and after confirming the return of all the passengers to the bus, the bus is to start to the next destination.
In the case of a great number of passengers, this confirmation work is not easy. For example, it takes effort and time to call the names with checking a passenger list. Therefore, techniques for effectively conducting this confirmation work have been proposed (see, for example, the below-mentioned Patent Documents 1 and 2).
In the inventions described in Patent documents 1 and 2, the getting-on/-off of a passenger is managed by exchanging radio signals between a tag (an IC tag) which the passenger holds and a device mounted on a bus. However, since tags for every passenger must be prepared, it costs much to construct the system. And if the passenger left behind the tag in the bus (on the seat), or somewhere outside the bus, it is impossible to correctly manage the passenger's getting-on/-off.
In case where a person illegally comes in to take the place of some passenger on the way and the person traveling illegally holds the passenger's tag, the replacement of passengers cannot be detected, that is, it cannot be detected that a suspicious person got on the bus on the way.

And by comparing the images of the passengers who got off after getting-on with the images of the passengers getting on after getting-off, the return state of the passengers can be appropriately managed without asking the passengers to hold a device for exclusive use such as an IC tag. Furthermore, it is possible to prevent a person different from the passengers getting off after getting-on, for example, a suspicious person from getting on, leading to securing the safety of passengers.
The embodiments of the passenger management apparatus and the passenger management method according to the present invention are described below by reference to the Figures. The below-described embodiments are preferred embodiments of the present invention, and various technically preferred limitations are included. However, the technical scope of the present invention is not limited to these modes, as far as there is no description particularly limiting the present invention in the following explanations.
The passenger management apparatus 1 according to the embodiment (1) comprises a getting-on passenger camera 10, a getting-off passenger camera 20, a clock section 30, a storage section 40, a microcomputer 50, a display section 60, a communication section 70, and an operating section 80.
The getting-on passenger camera 10 is a camera for picking up an image of a passenger getting on, while the getting-off passenger camera 20 is a camera for picking up an image of a passenger getting off. Each of them, comprising a lens part, an imaging element such as a CCD sensor or a CMOS sensor, an image processing part, a storage part (none of them shown) and associated parts, can take moving images or still images. The image processing part consists of an image processor having a person detecting function whereby faces of persons are individually detected and the like. The person detecting function consists of, for example, a function wherein a person's face (an area matching a face) is detected in a picked-up image, feature points such as eyes, a nose and the ends of a mouth are extracted from the face image area, and with these feature points, the person's face is individually detected.
The getting-on passenger camera 10 is placed, for example, at a position near the entrance of a bus, where a face of a passenger getting on can be photographed. The getting-off passenger camera 20 is placed, for example, at a position near the exit of the bus, where a face of a passenger getting off can be photographed. Each of the getting-on passenger camera 10 and the getting-off passenger camera 20 may consist of two or more cameras. Or one camera may be used as both the getting-on passenger camera 10 and the getting-off passenger camera 20. Or one or more in-vehicle cameras mounted as a drive recorder which photographs the inside or outside of the vehicle, or as a vehicle periphery monitoring device may also serve as the getting-on passenger camera 10 and the getting-off passenger camera 20.
The clock section 30 comprises a clock circuit, having a function of recording the time when an image was picked up by the getting-on passenger camera 10 or the getting-off passenger camera 20.
The storage section 40 comprises a getting-on passenger image storing part 41 and a getting-off passenger image storing part 42. In the getting-on passenger image storing part 41, an image including a face of a passenger getting on picked up by the getting-on passenger camera 10 and its picked-up time are associated and stored. In the getting-off passenger image storing part 42, an image including a face of a passenger getting off picked up by the getting-off passenger camera 20 and its picked-up time are associated and stored. The storage section 40 may consist of, for example, one or more semiconductor memories such as flush memories or a hard disk device, and not only an internal memory but also an external memory may be applied.
The microcomputer 50 has a function of conducting various kinds of computation processing and information processing, comprising one or more processors (CPUs), a RAM, a ROM and the like. The microcomputer 50 has functions as a passenger number detecting part 51a for detecting the number of persons on board on the basis of information stored in the getting-on passenger image storing part 41 and the getting-off passenger image storing part 42, and a passenger number informing part 51b for displaying the number of passengers detected by the passenger number detecting part 51a on the display section 60. In addition, it has functions as a getting-on/-off passenger comparing part 52a for comparing a passenger who got off after getting-on with a passenger getting on after getting-off (image recognition processing) on the basis of the information stored in the getting-on passenger image storing part 41 and the getting-off passenger image storing part 42, and a comparison result informing part 52b for displaying the result of comparison in the getting-on/-off passenger comparing part 52a on the display section 60. In the microcomputer 50, programs and data for implementing each of these functions are stored. As the getting-on/-off passenger comparing part 52a, an image identification (face identification) system into which artificial intelligence (AI) is incorporated may be adopted. As each of the above informing processing, not only displaying on the display section 60, but also outputting a synthetic voice from a voice output part not shown may be adopted.
The display section 60 consists of a display unit such as a liquid crystal display or an organic EL display. The communication section 70 has a radio communication function for conducting data communications or telephonic communications with the outside through a communication network of every kind such as a mobile phone net or the Internet. The operating section 80 consists of an input unit such as a touch panel or operation buttons.
The passenger management apparatus 1 may also consist of a portable terminal device such as a tablet terminal having a camera function, a radio communication function and a comparatively large display part. Or the passenger management apparatus 1 may be constructed by a system using multiple portable terminal devices. Or the getting-on passenger camera 10 and getting-off passenger camera 20, and the other components including the storage section 40 and microcomputer 50, may be separately constructed so as to exchange information with each other through communications.
In step S1, on the basis of a prescribed start signal, the getting-on passenger camera 10 is started, and a passenger counter K1 is set to be zero (cleared) (step S2). And thereafter, imaging processing is started (step S3). The prescribed start signal includes, for example, an operation signal by a crew member (a manager of this apparatus), or a prescribed operation signal (e.g., an operation signal for door opening) received from the bus side. As the imaging processing, besides taking moving images, still images may be taken intermittently. Or only when a person is detected, imaging processing may be conducted.
In step S4, whether a face of a person was detected in the picked-up image is judged. When it is judged that a face of a person was detected therein, the operation goes to step S5, wherein the image including the face thereof is associated with its picked-up time and stored in the getting-on passenger image storing part 41.
As a method for detecting a face of a person in an image, for example, a method wherein an area (a rectangular area) matching a person's face is detected in a picked-up image, the positions of feature points such as eyes, a nose and the ends of a mouth are extracted from the face image area, and the person is individually detected on the basis of these positions of feature points, is adopted. Or other face detecting techniques may be applied. In the getting-on passenger image storing part 41, information of the image including the detected face of the person (including information such as the feature point positions on the face) is associated with the image's picked-up time and stored.
In step S6, one is added to the passenger counter K1, and in step S7, informing processing of displaying the number of passengers on the display section 60 is conducted. On the display section 60, for example, a sentence “The current number of passengers on board is ◯◯.” is displayed. The number of passengers may be also informed by a voice (a synthetic voice) from a voice output part (not shown).
In step S8, on the basis of a prescribed condition, whether getting-on of all of the passengers scheduled to get on was completed is judged. The prescribed condition includes, for example, a case where the passenger counter K1 reached the predetermined number or the maximum number of passengers, a case where a getting-on completion operation was inputted by a crew member, or a case where an input of an entrance door closing operation was received from the bus side. When it is judged that getting-on of all of the passengers scheduled to get on has not been completed yet in step S8, the operation returns to step S4. On the other hand, when it is judged that getting-on of all of the passengers scheduled to get on was completed, the operation goes to step S9, wherein the reading of the counter K1 is stored as the number of passengers. Then, the processing is finished.
In step S11 shown in
In step S14, whether a face of a person getting off was detected in the picked-up image is judged. When it is judged that a face of a person was detected therein, the operation goes to step S15, wherein the image including the face thereof is associated with its picked-up time and stored in the getting-off passenger image storing part 42.
As a method for detecting a face of a person in an image, the same method as the method for detecting a person by the getting-on passenger camera 10 is adopted. In the getting-off passenger image storing part 42, information of the image including the detected face of the person (including information such as the feature point positions on the face) is associated with the image's picked-up time and stored.
In step S16, one is added to the getting-off passenger counter K2, and the reading of K2 is deducted from the reading of K1. Thereafter, in step S17, informing processing of displaying the number of getting-off passengers (the reading of K2) and the number of passengers staying in the bus (the value of K1−K2) on the display section 60 is conducted.
In step S18, whether the number of passengers staying in the bus (K1−K2) decreased to zero is judged. When it is judged that the number of passengers staying in the bus is not zero, the operation returns to step S14. On the other hand, when it is judged that the number of passengers staying in the bus is zero in step S18, the reading of the getting-off passenger counter K2 is stored as the number of getting-off passengers (step S19). Then, the processing is finished.
In step S21 shown in
In step S24, whether a face of a person getting on was detected is judged. When it is judged that a face of a person was detected, the operation goes to step S25. In step S25, processing of comparing the image including the face of the person concerned with a getting-off passenger image stored in the getting-off passenger image storing part 42 (image recognition processing) is conducted. In the face comparison processing, the image including the face thereof and each of the getting-off passenger images stored in the getting-off passenger image storing part 42 are compared. To the comparison, for example, face identification processing wherein the positions, sizes and heights of feature points of a face, such as eyes, a nose and a mouth, and the outline of the face extracted from each image are compared, and based on the degree of similarity of these feature points, whether they are the same person is judged, may be applied. Other face identification techniques may be also applied.
In step S26, whether the image of the face thereof matched one of the face images of the getting-off passengers stored in the getting-off passenger image storing part 42 is judged. When it is judged that there is a match, the operation goes to step S27. In step S27, the image including the face thereof is associated with its picked-up time and stored in the getting-on passenger image storing part 41.
In step S28, one is added to the getting-on passenger counter K3, and the number of passengers having not yet returned (K2−K3) and the number of passengers on board (K1−K2+K3) are calculated. Then, the operation goes to step S29, wherein informing processing of displaying the calculated numbers of passengers having not yet returned (K2−K3) and passengers on board (K1−K2+K3) on the display section 60 is conducted. In step S30, whether the number of passengers having not yet returned (K2−K3) decreased to zero is judged. When it is judged that the number of passengers having not yet returned is not zero (some passengers have not yet returned), the operation returns to step S24. On the other hand, when it is judged that the number of passengers having not yet returned is zero (all of the passengers returned) in step S30, the processing is finished.
On the other hand, when it is judged in step S26 that the image of the face thereof matches none of the face images of the getting-off passengers stored in the getting-off passenger image storing part 42 (there is no match), the operation goes to step S31. In step S31, informing processing of displaying the result of no match on the display section 60 is conducted, and the operation goes to step S30.
By the informing processing conducted in step S31, the crew member can know at once that the person getting on is not a passenger getting on again. As a result, the crew member can soon ask the person getting on if he/she got on a wrong bus. In the case of a tour using multiple buses, processing may be conducted, wherein the face image of the person concerned is sent to the passenger management apparatuses 1 mounted on the other buses, image comparison processing is conducted in the passenger management apparatus 1 of each bus, and those comparison results are received and informed. When a construction wherein a plurality of passenger management apparatuses 1 are used in cooperation is adopted, it is possible to quickly tell a person who got on a wrong bus which bus he/she should get on.
Using the passenger management apparatus 1 according to the embodiment (1), on the basis of the images of the getting-on passengers with each picked-up time stored in the getting-on passenger image storing part 41, and the images of the getting-off passengers with each picked-up time stored in the getting-off passenger image storing part 42, the number of persons in the bus (the number of passengers) can be continuously managed. And by comparing the face images of the passengers who got off after getting-on with the face images of the passengers getting on after getting-off (face identification), the return state of the passengers can be appropriately managed without asking the passengers to hold a device for exclusive use such as an IC tag. In addition, it is possible to prevent a person different from the passengers who got off after getting-on, for example, a suspicious person from getting on, leading to maintaining the safety of passengers.
The passenger management apparatus 1A according to the embodiment (2) further has a fingerprint sensor 31 for reading fingerprints of passengers getting on/off. It also has a function of making an access to an outside suspicious person information registration server 4 through a communication network 2 when the comparison result of face images (face identification result) shows that there is no match, so as to receive and inform the result of comparison with suspicious person data conducted in the suspicious person information registration server 4.
The passenger management apparatus 1A according to the embodiment (2) comprises a getting-on passenger camera 10, a getting-off passenger camera 20, a clock section 30, the fingerprint sensor 31, a storage section 40A, a microcomputer 50A, a display section 60, a communication section 70A, and an operating section 80.
The fingerprint sensor 31, for example, consists of a semiconductor-type fingerprint sensor, having a function of detecting changes in charge of electrodes which are different depending on the unevenness of a fingerprint, converting these charge quantities to voltages, and further converting those to a fingerprint image, when a finger is put on the sensor. And it has a function of extracting feature points such as a center point of the fingerprint pattern, and branching points, endpoints and deltas of the fingerprint ridge pattern, from the acquired fingerprint image. The fingerprint sensor 31 may be placed at a position where one can easily touch it by finger in getting-on/-off, for example, it is preferably placed near the entrance door or exit door of the bus.

Then, the processing is finished.
In step S21 shown in
In step S61, whether a fingerprint was detected by the fingerprint sensor 31 is judged. When it is judged that a fingerprint was detected in step S61, the operation goes to step S62. In step S62, processing of comparing the image including the face of the person concerned and the fingerprint information with the information stored in the getting-off passenger image storing part 42A (getting-off passenger images and fingerprint information, or getting-off passenger images) (face and fingerprint identification processing, or face identification processing) is conducted.
In the fingerprint identification processing, the fingerprint image of the person concerned and each of the fingerprint information of the getting-off passengers stored in the getting-off passenger image storing part 42A are compared. To the comparison, for example, a method wherein feature points of a fingerprint, such as a center point of the fingerprint pattern, and branching points, endpoints and deltas of the fingerprint ridge pattern, are extracted from each fingerprint image, these feature points are compared, and based on the degree of similarity of these feature points, whether they are the same person is judged, may be applied. Other fingerprint identification techniques may be also applied.
In step S63, whether the face image and fingerprint thereof matched the face image and fingerprint of a getting-off passenger stored in the getting-off passenger image storing part 42A is judged.

In step S66, whether the face image of the person concerned matched the face image of a getting-off passenger stored in the getting-off passenger image storing part 42A is judged. When it is judged that there is a match, the operation goes to step S67. In step S67, the image including the face thereof is associated with its picked-up time and stored in the getting-on passenger image storing part 41A, and then, the operation goes to step S28. Since the processing operations in steps S28-S30 are similar to those in steps S28-S30 shown in
On the other hand, when it is judged that there is no match in both the face images and fingerprints of the getting-off passengers in step S63, the operation goes to step S68, wherein the image and fingerprint information of the passenger getting on is sent to the suspicious person information registration server 4. Thereafter, the operation goes to step S70.
In step S66, when it is judged that the face image thereof matched none of the face images of the getting-off passengers in step S66, the operation goes to step S69, wherein the image of the passenger getting on is sent to the suspicious person information registration server 4. Thereafter, the operation goes to step S70.
In step S70, the suspicious person comparison result sent from the suspicious person information registration server 4 is received, and thereafter, the operation goes to step S71, wherein whether the suspicious person comparison result shows that the person is a suspicious person (the person matches a certain suspicious person) is judged. When it is judged that the person is a suspicious person, the operation goes to step S72. In step S72, processing of reporting the information that a suspicious person got on to an outside report organization 5 such as the police/the security police or a security company is conducted, and thereafter, the operation goes to step S74. On the other hand, when it is judged that the person is not a suspicious person (there is no match in suspicious persons) in step S71, the operation goes to step S73, wherein informing processing of displaying that the person got on a wrong bus on the display section 60 is conducted. Then, the operation goes to step S74, wherein the getting-on passenger counter K3 remains as it is, and the number of passengers having not yet returned (K2−K3) and the number of passengers staying in the bus (K1−K2+K3) are obtained. Then, the operation goes to step S29.

In addition, using the passenger management apparatus 1C, by the passenger information associating part 54a, the image of the passenger who got on and the image of the passenger who got off are associated (bound) with the information of the name, seat position and telephone number of the passenger. Consequently, not only the number of passengers but also the positions and number of vacant seats of the bus can be managed. Furthermore, since whether the number of vacant seats is correct in relation to the number of passengers is judged and the judgment result is informed, the crew member can check the number of passengers at once, leading to confirmation of omission of detection or double detection of some passenger, when the number of vacant seats is not correct in relation to the number of passengers.
Using the passenger management apparatus 1C, a position information request signal is sent to the portable terminal device 6 of the passenger who did not return by the expected time of return, position information sent from the portable terminal device 6 is received, and the received position information is informed. As a result, the crew member can grasp the position of the passenger who did not return at the expected time. And by receiving the position information of the passenger having not yet returned time by time, the return state of the passenger having not yet returned (for example, a state of coming toward the bus) can be also grasped.
In the passenger management apparatus 1C according to the embodiment (4), using the code reading section 32, a code on a passenger ticket is read, and passenger information recorded in the code is stored. On the other hand, in the passenger management apparatus 1D according to the embodiment (5), comparison instruction data including an image picked up by a getting-on passenger camera 10 is sent to a passenger information database server 7, and passenger information received from the passenger information database server 7 is associated with a getting-on passenger image or a getting-off passenger image.
In the passenger management apparatus 1C according to the embodiment (4), position information is requested to a passenger who did not return by the expected time of return. On the other hand, in the passenger management apparatus 1D according to the embodiment (5), position information is periodically received from a portable terminal device 6 of a getting-off passenger, and when it is judged that the passenger cannot return by the expected time of return from the position information, a call signal is sent thereto.

When it is judged that the passenger can return, the operation goes to step S30. On the other hand, when it is judged that the passenger cannot return in step S153, the operation goes to step S154, wherein a call signal is sent to the portable terminal device 6 of the passenger concerned, and then, the operation goes to step S30. The call signal is a signal for urging the passenger to return, including a calling signal of a telephone, messaging such as e-mail and the like.
In step S30, whether the number of passengers having not yet returned (K2−K3) decreased to zero is judged. When it is judged that the number of passengers having not yet returned is not zero (some passengers have not yet returned), the operation returns to step S24. On the other hand, when it is judged that the number of passengers having not yet returned is zero, the processing is finished.
Using the passenger management apparatus 1D according to the embodiment (5), the same effects as the passenger management apparatus 1C according to the embodiment (4) can be obtained. Furthermore, using the passenger management apparatus 1D, the comparison instruction data including an image of a passenger getting on is sent to the passenger information database server 7, the comparison result is received from the passenger information database server 7, and when the comparison result is a match, passenger information received with the comparison result is stored, and the passenger information and the image of the getting-on passenger are associated. Consequently, when a passenger gets on a bus at the spot of departure and the like, the image of the passenger getting on makes it possible to automatically associate the passenger with the passenger information, even if a crew member does not directly check the name of the passenger or a passenger ticket thereof. As a result, it can save the crew member some work, leading to enhanced convenience.
Using the passenger management apparatus 1D, position information is received from a passenger who got off at established intervals, and when it is judged that the passenger cannot return by the expected time from the position information, a call signal is sent to the portable terminal device 6 of the passenger who cannot return. Therefore, the timing of sending a call signal can be controlled depending on the position of the passenger having not yet returned, calling can be conducted with appropriate timing so as to enable the passenger to return by the expected time, and it is possible to prevent the return of the passenger from being long delayed.
In the passenger management apparatus 1C according to the embodiment (4), using the code reading section 32, a code on a passenger ticket is read, and passenger information recorded in the code is stored. On the other hand, in the passenger management apparatus 1E according to the embodiment (6), the names and seat positions of passengers scheduled to get on are previously registered in a passenger information storing part 43B. And comparison instruction data including an image picked up by a getting-on passenger camera 10 is sent to a personal information database server 8, the comparison result is received from the personal information database server 8, and when the same name as personal information (name) included in the comparison result in the case of the comparison result being a match is registered in the passenger information storing part 43B, the passenger information and the getting-on passenger image are associated.
In the passenger management apparatus 1E according to the embodiment (6), information of baggage left by passengers is registered. When there is baggage of a passenger who did not return by the expected time, informing processing of urging checking or removing of the baggage is conducted.
