[0015]
The destination guidance system is centered on a central management server (management center) 1 installed on the center side (taxi company side). The management center 1 includes a network network (mobile communication network). Etc.) 2 are connected to in-vehicle terminals (taxi terminals) 3 on all business vehicles (taxi) side through 2, and between the management center 1 and each taxi terminal 3, data is transferred via a mobile communication network. Send and receive. In this case, for example, digitized (packetized) data is transmitted / received between the management center 1 and each taxi terminal 3 by the HTTP protocol using the TCP / IP communication protocol.
[0016]
The management center 1 accumulates and manages location information indicating the boarding place and the getting-off place of the route that the passenger has taken last time in association with the face image (customer identification information) of the passenger, and when the passenger gets on the taxi terminal 3 When the face image of the passenger photographed and the current position are transmitted, the location information is searched based on the face image, and the current getting-off location of the passenger is determined based on the location information and the current position. The taxi terminal 3 estimates and transmits the information to the taxi terminal 3, and the taxi terminal 3 displays the current drop-off place transmitted from the management center 1 for the crew and passengers.
[0017]
FIG. 2 is a block diagram showing basic components of the management center 1.
In the management center 1, the CPU 11 is a central processing unit that controls the overall operation of the management center 1 in accordance with an operating system and various application software in the storage device 12. The storage device 12 has a program storage area and a data storage area, and is configured by a magnetic, optical, semiconductor memory, or a drive system thereof. The recording device 12 may have a configuration in which a removable storage medium such as a CD-ROM or DVD can be mounted in addition to a fixed memory such as a hard disk.

On the other hand, a communication device 14, an input device 15, and a display device 16 as input / output peripheral devices are connected to the CPU 11 via a bus line, and the CPU 11 controls their operations according to an input / output program.
[0018]
On the management center 1 side, a customer database 17 is provided which is referred to when a customer destination is guided and output. The customer database 17 accumulates and manages a passenger's face image (customer identification information) and location information (location information of longitude and latitude) indicating the boarding place and alighting place of the route that the passenger has taken the previous time for each passenger. Is.
FIG. 3 is a diagram showing the contents of the customer database 17. Each customer record constituting the customer database 17 includes “management number (serial number)”, “image data (face image)”, “boarding position”. Each item of “azimuth data” and “alighting position direction data” is stored. “Boarding position direction data” and “alighting position direction data” are longitude and latitude information for indicating a boarding location / alighting location.
[0019]
FIG. 4 is a block diagram showing basic components of the taxi terminal 3.
The taxi terminal 3 is based on a CPU 31 that controls the overall operation of the taxi terminal 3 according to an operating system and various application software. The taxi terminal 3 is an input / output peripheral device in addition to the CPU 31 and the RAM 32. An electronic camera 33, a GPS (position measuring system) 34, a driver display device 35, a driver input device 36, a passenger display device 37, a passenger input device 38, and a communication device 39 are provided. The current getting-off place estimated by the management center 1 is displayed as guidance on the driver display device 35 and the passenger display device 37, respectively.
[0020]
The electronic camera 33 is, for example, a digital video camera or a digital still camera that is installed on a backrest portion of a driver's seat or a passenger seat and uses a CCD image sensor or the like as an image pickup device. When this is detected, the electronic camera 33 is activated to obtain a photographed image photographed from the front direction around the passenger's face, and this photographed image (color image) is transmitted to the management center 1. Like to do.
The position measurement system (GPS) 34 obtains the current position (boarding place / alighting place) via a terrestrial / satellite mobile communication network at the time of boarding / alighting. At the same time, the position data of the boarding place is transmitted to the management center 1.
[0021]
Next, the operation concept of the destination guidance system in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in the flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. It is also possible to sequentially execute operations according to the program code transmitted via the transmission medium. The same applies to other embodiments to be described later. In addition to a recording medium, an operation peculiar to this embodiment can be executed using a program / data supplied externally via a transmission medium.
[0022]
FIG. 5 is a flowchart showing an overview of the getting-off place guidance process executed between the management center 1 and the taxi terminal 3.
First, when the taxi terminal 3 detects that the boarding door is opened during boarding, the taxi terminal 3 activates the electronic camera 33 and takes a photographed image taken from the front direction around the passenger's face. While acquiring (step A1), the position measurement system (GPS) 34 is started and the present position (azimuth position of a boarding place) is acquired (step A2). Then, the management center 1 is called to make an inquiry request, and the face image data and the azimuth position data of the boarding location are transmitted to the management center 1 (step A3). Here, even after the taxi terminal 3 transmits the face image data and the azimuth position data of the boarding location to the management center 1, the taxi terminal 3 temporarily stores and holds them until the passenger gets off (step A4). .
[0023]
When the management center 1 receives an inquiry request from the taxi terminal 3, the face image data and the azimuth position data of the boarding location transmitted from the taxi terminal 3 are received and acquired, and then the face image is received. The customer database 17 is accessed based on the data, and the face image is collated (step B1). As a result, whether the customer this time is a passenger who has used a taxi of the taxi company even once in the past. It is checked whether the passenger is a new passenger for the first time (step B2).
In this case, image data (registered images) of all passengers registered in the customer database 17 are sequentially read out and feature comparison with the current passenger image data is performed. After correcting the above, the shape, position, size, hairstyle, presence / absence and type of glasses, etc. of the face outline, eyes, mouth, nose, forehead, etc. are individually compared, and image comparison is performed by comprehensively comparing them. (The same applies hereinafter).
[0024]
As a result of the feature comparison of face images in this way, if there is a corresponding image that matches characteristically in the customer database 17, registered customers who have used our taxi once in the past. If there is no corresponding image, it is recognized as a new customer (unregistered customer). If it is recognized that the customer is a new customer (unregistered customer) (NO in step B2), the requesting taxi terminal 3 is notified of such guidance (step B3).
[0025]
After the taxi terminal 3 receives the notification that it is a new customer, when this passenger gets off, the taxi terminal 3 activates the GPS 34 and acquires the current position (azimuth position of the drop-off place) (step A5). Then, at the time of boarding, the face image data and the azimuth position data of the boarding place temporarily stored are read out and transmitted to the management center 1 as information about the new customer together with the azimuth position data of the getting off place (step A6). Thereafter, the face image data of the passenger, the azimuth position data of the boarding place and the getting off place are deleted as unnecessary information.
When the management center 1 receives the face image data and the azimuth position data of the boarding location and the getting-off location as information about the new customer from the taxi terminal 3, the management center 1 generates a record of the new customer including them and stores it in the customer database 17. Additional registration is performed (step B4).
[0026]
On the other hand, if it is a registered customer who has used our taxi even once in the past (YES in step B2), the previous boarding location and getting-off location associated with the registered customer from the customer database 17 Is read out (step B5). Then, the distance relationship between the current position of the taxi terminal 3 and the previous boarding / alighting place is calculated (step B6). That is, the distance between the current position and the boarding place is calculated, and the distance between the current position and the getting off place is calculated. As a result, it is checked whether or not the current position is closer to the previous boarding place (step B7).
[0027]
If it is closer to the previous boarding location (YES in step B7), the current getting-off location is estimated as the previous getting-off location (step B8). In other words, if this time boarding in the vicinity of the previous boarding place, it is presumed that the car will get off at the same place as the previous time. Further, if it is closer to the previous drop-off place (NO in step B7), the current drop-off place is estimated as the previous drop-off place (step B9). That is, when this time boarding near the previous getting-off place, it is estimated that it is a case where the same route is reciprocated by taxi (in the case of a return route).
[0028]
After estimating the current drop-off location in this way, the management center 1 reads the azimuth position of this drop-off location from the customer database 17 and notifies the requesting taxi terminal 3 (step B10).
Then, the taxi terminal 3 automatically inputs the azimuth position of the getting-off place transmitted from the management center 1 to the GPS 34, and displays the route (a map clearly showing from the current position to the getting-off place) for the driver. Information is displayed on the device 35 and the passenger display device 37 (step A7).
[0029]
As described above, in the first embodiment, the management center 1 stores and manages in the customer database 17 the azimuth position data of the boarding place and the getting-off place of the route that the passenger has taken last time in association with the face image of the passenger. When the passenger gets on the face image of the passenger photographed from the taxi terminal 3 and the current position (boarding position) is transmitted, the customer database 17 is searched based on the face image, and the corresponding The azimuth position data of the boarding location / alighting location is read out, the current location is estimated based on the azimuth location data of the boarding location / alighting location and the current location, and is sent to the taxi terminal 3 to be transmitted to the taxi terminal 3 In consideration of the fact that passengers often go through the same route many times, because the guidance of the current alighting place sent from the management center 1 is output. If the customer passes the previous route this time, he / she can accurately guide the place to get off this time based on the previous route, and does not place an extra burden on passengers. Providing highly practical guidance services such as being able to respond very quickly, and also expecting fixed customers to be fixed customers by providing useful services, enabling differentiation from competitors in the same industry. It becomes possible.
[0030]
In this case, as a result of searching the customer database 17 based on the passenger face image, if the corresponding image is not registered, the management center 1 recognizes the unregistered customer as a new customer, and information about the new customer ( New records are generated based on the face image data, the azimuth position data of the boarding place and the getting off place), and additionally registered in the customer database 17, so that information about new customers can be automatically stored and input. This saves you time and effort.
Further, since the taxi terminal 3 is configured to guide and output the route from the current location to the getting-off location based on the current location information of the getting-off location estimated by the management center 1, the route to the getting-off location is specifically described. As a result, the convenience is further increased, and it is not necessary to indicate the traveling direction for each intersection.
[0031]
The management center 1 calculates the distance relationship between the current position of the taxi terminal 3 and the previous boarding / alighting place, and if the current position is closer to the previous boarding place, this time also near the previous boarding place Since it is a case of getting on, it is estimated that this time it will get off at the same place as the previous time, and when it is closer to the previous place of getting off (when this time getting on near the previous place of getting off), the same route is taken Since there is a high possibility of going back and forth by taxi (in the case of a return trip), it is possible to estimate the current place of getting off as the previous boarding place.
[0032]
(Second Embodiment)
A second embodiment of the present invention will be described below with reference to FIGS. In addition, in the first embodiment described above, the customer database 17 stores and manages information (direction position data of a boarding place / alighting place) regarding the route (usage route) taken last time for each passenger. The customer database 17 in the second embodiment is configured to be able to store information on a plurality of usage routes corresponding to one passenger.
[0033]
And in this 2nd Embodiment, the use route close | similar to the present position (boarding position) is selected from the some use route which the passenger has passed by taxi, and it is estimated based on the information regarding this selection route. In addition to guiding and displaying the current drop-off location as the first candidate data, other use routes are sequentially selected in order from the closest to the current position, and each get-off location estimated for each selected route is used as data after the second candidate. A guidance display is provided.
Here, components that are basically the same in both embodiments are denoted by the same reference numerals, description thereof will be omitted, and the following description will focus on the features of the second embodiment.
[0034]
FIG. 6 is a diagram showing the contents of the customer database 17 in the second embodiment.
The customer database 17 is configured to be able to store information on a plurality of usage routes corresponding to one passenger. In other words, each customer-corresponding record has its “management number”, “image data”, “use route”, “ride location”, “get off location”, “ride location data”, and “get off location data”. In addition to having an item, each “use route” has its “boarding location”, “disembarking location”, “ride location data”, and “drop location data”, and has been used in the past. It stores and manages information related to a plurality of usage routes.
[0035]
FIG. 7 is a flowchart showing an overview of the getting-off place guidance process executed between the management center 1 and the taxi terminal 3 in the second embodiment.
First, as in the first embodiment described above, when the taxi terminal 3 detects that the boarding door is opened during boarding, the taxi terminal 3 activates the electronic camera 33 and photographs the passenger's face in front. The captured image is acquired (step A11), the GPS 34 is activated to acquire the current position (boarding position) (step A12), and these are transmitted to the management center 1 (step A13). Here, even after transmitting the face image data and the boarding position to the management center 1, the taxi terminal 3 temporarily stores and holds them until the passenger gets off (step A14).
[0036]
As in the first embodiment described above, the management center 1 receives and acquires the face image data and the boarding position data transmitted from the taxi terminal 3, and then accesses the customer database 17 based on the face image data. The face image is collated (step B11), and it is checked whether it is a passenger who has used a taxi of the taxi company in the past or a new passenger (step B12). If it is a new customer (unregistered customer), The request is notified to the requesting taxi terminal 3 (step B13).
Here, when the taxi terminal 3 receives the notification of the new customer, when the passenger gets off, the taxi terminal 3 activates the GPS 34 to acquire the current position (alighting position) (step A15), and temporarily holds it when getting on. Along with the face image and the boarding position, the alighting position is transmitted to the management center 1 as information on the new customer (step A16). When the management center 1 receives information on the new customer (facial image data, azimuth position data of the boarding location and the getting-off location) from the taxi terminal 3, the management center 1 generates new records including them and additionally registers them in the customer database 17 (steps). B14).
[0037]
On the other hand, if the management center 1 determines that it is a registered customer that has been used in the past (YES in step B12), for each usage route associated with the registered customer from the customer database 17, The azimuth position data of the boarding and getting-off places is read (step B15), and the distance relationship between the current position (boarding position) and the boarding and getting-off places for each use route is calculated for each use route (step B16). In this case, the actual distance on the route may be calculated without being limited to calculating the linear distance between the current position and the boarding / alighting place of each use route.
[0038]
FIG. 8 is a diagram illustrating a distance calculation example. That is, for example, for each of a plurality of usage routes “D”, “E”, and “F” used by a passenger with the management number “000002”, from the current position (boarding position) to the boarding / departing place of each usage route Is a diagram showing a calculation example in the case of calculating the distance of, showing that the current boarding position is closest to the place of use (E condominium) of the usage route “E”, then E station, F bank, etc. It shows that they are close in order.
[0039]
Then, the management center 1 refers to the result of the distance calculation to select a usage route that is close to the current boarding position from among a plurality of usage routes, and information on the selected route (the azimuth position of the boarding / alighting location) Data) is determined as the first candidate data, and other use routes are selected in order from the closest to the current boarding position, and the current getting off estimated for each selected route The location is determined as data after the second candidate.
[0040]
FIG. 9 is a diagram showing a ranking result in which the candidate data of the alighting places determined for each use route as described above are arranged according to the priority order.
In this case, since the current boarding position is closest to the place where the use route “E” gets off (E condominium), this use route “E” is preferentially selected. At this time, the distance between the current location and “E Mansion” is 30m, and it is in the vicinity of “E Mansion”, and it is not possible to use a taxi. Is determined as the first candidate. The next closest use route to the current location is “F”, and the boarding location (F station) of the use route “F” is determined as the second candidate from the distance relationship between the boarding / alighting location and the current location. Further, the place of getting off (bank F) of this usage route “F” is determined as the third candidate. Then, in the last remaining usage route “D”, the boarding location (D station) is determined as the fourth candidate from the distance relationship between the boarding / alighting location and the current position, and the boarding location (D stadium) is Determined as 5 candidates.
[0041]
The management center 1 reads out the azimuth position data from the customer database 17 and notifies the taxi terminal 3 for each boarding place candidate determined with priorities in this way (step B17).
Then, the taxi terminal 3 automatically inputs the azimuth position data of each disembarkation location transmitted from the management center 1 to the GPS 34, acquires each disembarkation location obtained thereby (step A17), and each of these disembarkation locations. Are displayed as a selection candidate (step A18). When the passenger touches and designates the position to select the current drop-off location from the list screen (step A19), the azimuth position data of the selected candidate (drop-off location) is automatically input to the GPS 34 (step A20). ), The route obtained from this (the route from the current position to the place of getting off) is displayed on the driver display device 35 and the passenger display device 37 (step A21).
[0042]
If the current drop-off location is not listed in the list screen, that is, if no candidate is selected, this is detected in step A19, and the process moves to step A15. When starting, the GPS 34 is activated to acquire the current position (alighting position), and the getting-off position is transmitted to the management center 1 as information on the new route together with the face image and the boarding position temporarily held when the passenger gets on. (Step A16).
When the management center 1 receives the information (face image data, azimuth position data of the boarding location and the getting-off location) related to the new route transmitted from the taxi terminal 3, it is used as a new route in the corresponding record of the customer database 17. Additional registration is performed (step B14).
[0043]
As described above, in the second embodiment, the management center 1 selects a use route that is close to the current position (boarding position) from among a plurality of use routes that passengers have taken by taxi in the past. Since the current drop-off location estimated based on the route information is sent to the taxi terminal 3 for guidance, even passengers using multiple routes can accurately guide the current drop-off location It is possible to use the passengers repeatedly in a wider area.
[0044]
In this case, select the usage route close to the current position from the multiple usage routes that passengers have taken by taxi, and the first candidate's data on the current location of departure estimated based on the information about this selected route The other use routes are sequentially selected in order from the closest to the current position, and the respective get-off places estimated for each selected route are guided as data after the second candidate. It is possible to arbitrarily select the place to get off this time from the candidate group determined every time. In addition, when the current drop-off location does not exist in the candidate group determined for each use route, the current route can be additionally registered in the customer database 17 as a new route for the passenger.
[0045]
FIG. 10 is a diagram showing a modified application example of the customer database in the second embodiment described above.
As with the second embodiment described above, each customer-corresponding record constituting the customer database has its “management number” and “image data” as well as “boarding place”, “getting place”, “ Although it has each item of "boarding position direction data" and "alighting position direction data", the customer database shown in FIG. 10 further includes "use count", "driving distance" for each "use route", It has items of “normal charge” and “late-night charge” and “cumulative distance” used by passengers in the past.
[0046]
In this case, as the usage status of passengers, it is possible to obtain materials such as “number of uses”, “driving distance”, “normal charge”, “late night charge” for each “use route” and “cumulative distance” for each passenger. ", It is possible to provide appropriate customer services such as distribution of souvenirs, and it is possible to eliminate or reduce the daily report of crew members. Furthermore, if the route of use of the new passenger is substantially the same as the route of use of other passengers registered in the customer database 17, the “normal charge” and “late-night charge” of the use route are presented to the new passenger. Is also possible.
[0047]
Although not particularly mentioned in the first and second embodiments described above, if the image data in the customer database is rewritten for each ride, the registered face image is always the latest information, and the image The recognition rate at the time of comparison can be greatly improved.
Furthermore, in the first and second embodiments described above, one type of face image is registered for each passenger. However, in order to improve the recognition rate during image comparison, a plurality of faces with different shooting directions and the like are used. You may make it register an image for every passenger.
[0048]
In the first and second embodiments described above, “boarding position direction data” and “getting off position direction data” are registered in the customer database, but the name and address of the boarding place and the getting off position are registered, Based on the name and address, “boarding position / direction data” and “alighting position / direction data” may be obtained.
In the first and second embodiments, the current getting-off place is displayed for guidance to the crew and passengers, but voice guidance may be provided.
[0049]
Further, in the first and second embodiments described above, the passenger face image is the customer identification information, but the customer identification information may be the fingerprint information. In this case, when the taxi terminal 3 is provided with a fingerprint authentication device, fingerprint information is registered for each passenger in the customer database on the management center 1, and the fingerprint information detected at the time of boarding is transmitted to the management center 1, the management center 1 1 may search a customer database based on this fingerprint information to perform passenger verification. Furthermore, face image authentication and fingerprint authentication may be used in combination, or if authentication of one of them cannot identify a customer, other authentication may be used in combination.
[0050]
In the first and second embodiments described above, the case of using a taxi has been exemplified. Of course, the present invention can be similarly applied to the case of using a higher taxi.
Furthermore, not only taxi and hire use, but also destination guidance when using the facility may be used. For example, in a downtown area, a theme park, or the like, a customer service for guessing and guiding a current destination based on information on a past route to a repeat customer may be implemented.
[0051]
On the other hand, a recording medium (for example, a CD-ROM, a floppy disk, a RAM card, etc.) on which a program code for executing each of the above-described units is recorded may be provided to the computer. That is, a recording medium having a program code readable by a computer, and location information indicating at least the end point of the route that the customer has taken in the past in association with customer identification information.
