  In the conventional method described above, the reader / writer detects an IC tag in a predetermined area to identify the visitor's position, and distributes information based on the visitor's position. It can also be applied to the distribution of electronic data.

  However, since the conventional method uses the RFID (Radio Frequency Identification) to identify the location of the visitor, if the exhibition booths are close to each other, the visitor can select a predetermined number of exhibition booths. There was a problem that the information about the desired exhibition booth could not be received due to entering the area.

  In addition, the conventional method is aimed at distributing information, and in the first place, it is not known where the exhibition booth to be observed is. For this reason, there is a case where the information provided by the exhibition booth is received when approaching an unintended exhibition booth. In such a case, it is necessary to go back and forth between the exhibition booths, and the desired exhibition booth is provided. There is also a problem that information to be acquired cannot be acquired efficiently.

  The present invention has been made in view of the above problems, and its main purpose is to provide an exhibition tour support system and an information display for supporting a visitor so that information provided by a desired exhibition booth can be reliably acquired. To provide an apparatus.

  In order to achieve the above object, the present invention provides an exhibition tour support system comprising at least a plurality of exhibition booths arranged at an exhibition hall and an information display device carried by a visitor entering the exhibition hall. The exhibition booth includes a light source that transmits ID information indicating its booth number as a blinking pattern by visible light communication, and the information display device defines a display unit and positions of the plurality of exhibition booths in the exhibition hall At least a storage unit that stores layout information, an imaging unit that can capture a moving image, and a control unit, wherein the control unit positions the plurality of light sources from images of moving image data that captures a plurality of exhibition booths. The ID information is acquired from the blinking pattern of each of the light sources, and based on the positions of the plurality of light sources, the ID information, and the layout information. The information display device relative to the imaged exhibition booth is identified, and a guide screen on which the information display device, the exhibition booth in the vicinity thereof, and the ID information of the exhibition booth are displayed is displayed on the display unit. It is what is displayed.

  The present invention is also an information display device used in an exhibition hall where a plurality of exhibition booths having a light source for transmitting ID information indicating its own booth number as a blinking pattern by visible light communication is disposed, A storage unit that stores layout information that defines the positions of the plurality of exhibition booths in the exhibition hall, an imaging unit that can capture a moving image, and a control unit, wherein the control unit includes a plurality of exhibitions. The positions of the plurality of light sources are identified from the image of the moving image data capturing the booth, the ID information is acquired from the blinking pattern of each of the light sources, and the positions of the plurality of light sources, the ID information, and the layout information are obtained. The information display device relative to the imaged exhibition booth is identified based on the information display device, the exhibition booth in the vicinity thereof, and the front of the exhibition booth. The guidance screen and the ID information is displayed is intended to be displayed on the display unit.

  According to the exhibition tour support system and the information display device of the present invention, it is possible to support the visitor so that the information provided by the desired exhibition booth can be acquired with certainty.

  The reason for this is that each exhibition booth arranged at the exhibition hall is provided with a light source that transmits ID information indicating its booth number as a blinking pattern by visible light communication. Process each image of the video that captured multiple exhibition booths, identify the location of the light source of each exhibition booth, obtain the ID information of the exhibition booth from the blinking pattern of the light source, Based on the ID information and pre-stored layout information, the relative position of the information display device with respect to the imaged exhibition booth is specified, and the information display device, the nearby exhibition booth, the ID information of the exhibition booth, and imaging as necessary This is because a guidance screen displaying directions is displayed.

And electronic data such as explanatory materials are transmitted wirelessly and can be viewed on the screen.

  Since this method eliminates the need for paper media, wasteful consumption of resources can be reduced. However, since the ID information is notified from each exhibition booth or a device in the vicinity thereof, when the exhibition booth is close Has a problem that ID information is notified from a plurality of adjacent exhibition booths, and electronic data of an unintended exhibition booth may be received.

  In addition, the conventional method is not intended to inform the visitor of the location of the exhibition booth, so it is difficult to know where the exhibition booth is to be visited, receiving electronic data from the unintended exhibition booth, There was also a problem of having to go back and forth between booths and re-receive electronic data.

  On the other hand, in recent years, visible light communication using an LED (Light Emitting Diode) illumination lamp has attracted attention. This visible light communication has directivity unlike radio waves, does not affect the human body, and is not restricted by the Radio Law. Therefore, a method of transmitting electronic data using visible light communication is also conceivable. However, visible light communication has a lower data transmission speed than wireless communication, and is not suitable for use in transmitting large-sized electronic data.

  Therefore, in one embodiment of the present invention, a light source for performing visible light communication is arranged at a predetermined position of each exhibition booth in the exhibition hall by a blinking pattern, and the booth number of the exhibition booth is indicated from the light source. ID information is continuously transmitted. On the other hand, a visitor carries an information display device and images a plurality of exhibition booths with moving images using the imaging function of the information display device. Then, the image of each frame of the moving image is processed to identify the position of the light source of each exhibition booth, ID information is acquired from the blinking pattern of the light source, the light source position and ID information of each exhibition booth, and layout information stored in advance Based on the above, the relative position of the information display device relative to the imaged exhibition booth is specified, and the information display device, the display booth in the vicinity thereof, the ID information of the exhibition booth, and the imaging direction as required are displayed. Is displayed. Thereafter, when a desired exhibition booth is selected from among the exhibition booths in the vicinity of the information display device, electronic data of the exhibition booth is acquired from storage means such as a server based on the ID information corresponding to the selected exhibition booth. Control to display.

  This makes it easy to know where the desired exhibition booth is, without having to carry around the layout of the exhibition hall. Without receiving the booth electronic data, it is possible to efficiently visit the exhibition hall and reliably acquire the electronic data of the desired exhibition booth.

  In order to describe the above-described embodiment of the present invention in more detail, an exhibition tour support system and an information display apparatus according to an embodiment of the present invention will be described with reference to FIGS.

The server 40 is arranged at an arbitrary place (either inside or outside the exhibition hall), and stores the electronic brochure of each exhibition booth 20 in association with the ID information. And if ID information is received from the information display apparatus 30, the electronic brochure corresponding to ID information will be specified, and the said electronic brochure will be transmitted to the information display apparatus 30 of the transmission source of ID information.

  1 and 2 are examples of the exhibition tour support system 10 of the present embodiment, and the configuration and control thereof can be changed as appropriate. For example, in FIG. 1, the electronic brochure is stored in the server 40, but the electronic brochures of all the exhibition booths 20 are stored in each information display device 30 and correspond to the ID information of the selected exhibition booth 20. You may make it read and display an electronic brochure. Further, storage means is provided in each exhibition booth 20 to store the electronic brochure of the exhibition booth 20 and the electronic brochure is transmitted to the information display device 30 that has transmitted the ID information of the exhibition booth 20. Also good. In these cases, the server 40 can be omitted, and the exhibition tour support system 10 can be composed of the exhibition booth 20 and the information display device 30.

  Next, a method for specifying the positional relationship between the exhibition booth 20 and the information display device 30 using the exhibition tour support system 10 having the configuration shown in FIG. 1 will be described.

  FIG. 3 is a plan view of a part of the exhibition hall as viewed from above. Here, nine exhibition booths A11 to A13, B11 to B13, and C11 to C13 are arranged. And the visitor stops in the area | region enclosed by the exhibition booth 20 of B12, B13, C12, and C13, and the imaging part 34 of the information display apparatus 30 assumes that the upper part of a figure is imaged.

  FIG. 4 is an example of a moving image captured by the image capturing unit 34 of the information display device 30 in this state, and each booth 20 of A12, A13, B12, and B13 is displayed. Since there are other visitors in the exhibition hall, the visible light communication light source 21 in the exhibition booth 20 (here, the visible light communication light source 21 in the exhibition booth 20 in B13) is blocked by other visitors as shown in FIG. Sometimes it is not reflected.

  FIG. 5A shows an image of each frame of the moving image captured in this way (a still image at three times when the visible light communication light source 21 is lit), from the right side to the left side of the figure. Other visitors are moving towards.

  FIG. 5B shows an image obtained by correcting the deviation of the imaging position by predetermined image processing (for example, the outline of the exhibition booth 20) with respect to the image of FIG. The display booth 20 is arranged at the same position in all the images.

  FIG. 5C is an image obtained by performing predetermined image processing (for example, processing for deleting points other than a predetermined luminance or higher) on the image of FIG. Only the visible light communication light source 21 is displayed.

  FIG. 5D shows that the visible light communication light source 21 shown in FIG. 5C is not displayed for a certain period of time because it is blocked by other visitors (here, the visible light communication light source of the booth B13). 21), and ID information is read from the continuous image of the visible light communication light source 21.

  The reading of this ID information will be described. Focusing on a certain visible light communication light source 21, as shown in FIG. 6A, the visible light communication light source 21 emits signal specifying information (information indicating visible light communication: for example, lighting at regular intervals). / Repeat pattern) and ID information of the exhibition booth 20 (for example, a light-off pattern at intervals different from the signal identification information) are repeatedly transmitted.

  The imaging unit 34 of the information display device 30 captures the lighting / extinguishing pattern of the visible light communication light source 21, but other exhibitors like the display booth 20 of A12, A13, and B12 in FIG. As shown in FIG. 6B, bright / dark corresponding to turning on / off of the visible light communication light source 21 is recorded in a continuous image obtained by capturing the visible light communication light source 21 that is not blocked. Therefore, when the lighting / extinguishing pattern is received N times continuously and the lighting / extinguishing patterns match, ID information can be acquired from the lighting / extinguishing patterns.

  On the other hand, as shown in the booth 20 of B13 in FIG. 5, the continuous image obtained by capturing the visible light communication light source 21 blocked by other visitors is dark for a certain period of time as shown in FIG. The status is recorded. Accordingly, if the dark state continues for a certain period of time, it is determined as abnormal, and the exhibition booth 20 is excluded from the ID information reading target, or the ID information is acquired from the continuous image after the dark state is resolved.

  The configuration of the signal specifying information and the ID information is not particularly limited, but when the lighting is set to “1” and the lighting is set to “0”, for example, as shown in FIG. 7, the signal specifying information is set to “1”, “0”. And ID information can be information expressed by a combination of “11” and “00”, and the lighting / extinguishing time interval between the signal specifying information and the ID information can be set as information that is repeated a predetermined number of times (for example, 128 times). By changing, it is possible to easily distinguish the signal specifying information from the ID information.

  Note that the signals from the visible light communication light sources 21 of the plurality of exhibition booths 20 may be synchronized (that is, the ID information may be transmitted at the same timing) or may be asynchronous. 6 and 7, the signal specifying information and the ID information are alternately sent from the visible light communication light source 21, but the signal specifying information may be omitted and only the ID information may be sent continuously. Alternatively, the visible light communication light source 21 may be turned on or off for a certain time before sending the ID information. In addition, the time interval between turning on / off in the signal specifying information and the ID information is not particularly limited, but it may be set in consideration of the frame rate of the moving image so that the lighting / lighting pattern can be recorded in the image of each frame of the moving image. preferable.

  Next, a method for specifying the relative position of the visitor (information display device 30) with respect to the exhibition booth 20 after specifying the position and ID information of the visible light communication light source 21 in the exhibition booth 20 will be described.

  As shown in FIG. 8, when three visible light communication light sources (P1 to P3) are recorded in an image captured at a certain photographing point (O point), they are on the same plane (the same height from the floor). Since the triangle formed by the three points arranged in a row is uniquely determined, the relative position of the photographing points (O points) with respect to P1 to P3 can be specified by a geometric method.

  Specifically, when the position (the real space coordinates) of the visible light communication light source 21 of each exhibition booth 20 is known in advance and stored as layout information, the real space of three or more visible light communication light sources is stored. By comparing the coordinates with the coordinates on the captured image, the scale, the rotation angle in the horizontal plane, and the elevation angle with respect to the horizontal plane can be specified. Therefore, the relative position of the shooting point (O point) with respect to the visible light communication light source 21 is determined. Can be identified.

  Even when the visible light communication light sources 21 are not on the same horizontal plane, if the height of each visible light communication light source 21 is known in advance, the photographing point (O point) is similarly corrected by correcting the vertical displacement. It is possible to specify the relative position of. In this embodiment, the visible light communication light sources are arranged in a matrix. However, the relative positions of the photographing points (O points) are the same even when the visible light communication light sources are arranged at random. It is possible to specify.

  Next, the overall operation of the exhibition tour support system 10 will be described with reference to the flowchart of FIG. 9 and the screen examples of FIGS.

  First, the visitor operates the information display device 30 to operate the imaging unit 34 and images a plurality of exhibition booths 20 with moving images for a certain period of time (S101).

  Next, the control unit 31 (control program) acquires the moving image data from the imaging unit 34, corrects the positional deviation of the image of each frame of the moving image data, specifies the effective visible light communication light source 21, and displays the visible light. ID information is acquired from the continuous image of the optical communication light source 21 (S102).

  Next, can the control unit 31 (control program) identify the positional relationship between the exhibition booth 20 and the information display device 30 (that is, whether ID information has been received from the visible light communication light sources 21 of the plurality of exhibition booths 20)? (S103) and if the positional relationship cannot be specified, the process returns to step S101 and the visitor captures a moving image again.

  On the other hand, when the positional relationship can be specified, the control unit 31 (control program) specifies the relative position of the information display device 30 with respect to the exhibition booth 20 imaged using the above method, and displays the position of the information display device 30 Is generated and displayed on the display unit 32 (S104). This screen (exhibition booth guidance screen 50) is configured as shown in FIG. 10, for example, and a visitor (that is, the information display device 30) and the surrounding exhibition booth 20 are displayed. The booth number specified by the ID information is displayed. Moreover, the direction imaged by the imaging unit 34 is displayed as necessary. By displaying such an exhibition booth guidance screen 50, the visitor can easily grasp where he / she is in the exhibition hall and can easily move to the desired exhibition booth 20. Become.

  Next, the control unit 31 (control program) specifies the exhibition booth 20 around the visitor based on the positional relationship between the exhibition booth 20 and the information display device 30, and assigns the booth number of the exhibition booth 20 to the exhibition booth 20. A screen for displaying a list in association with the names of companies exhibiting in the company is created and displayed on the display unit 32 (S105). This screen (exhibition booth selection screen 51) is configured as shown in FIG. 11, for example, and displays the exhibition booth 20 around the visitor (here, the exhibition booths B12, B13, and C12) to be selectable. A visitor operates the operation part 33 and selects the exhibition booth 20 (here, the exhibition booth 20 of B12) which wants to obtain an electronic pamphlet.

  Here, the display booth 20 is selected on the display booth selection screen 51, but the display booth 20 may be selected by instructing the desired display booth 20 on the display booth guidance screen 50. In addition, the display order of the exhibition booth 20 on the exhibition booth selection screen 51 is not particularly limited. For example, the display booth 20 that has not obtained an electronic brochure is displayed with a higher priority (displayed at the top), or a visitor. The display booth 20 with a short distance from the (information display device 30) is displayed with a higher priority (displayed at the top), or the display booth 20 near the center is displayed with a higher priority in the horizontal direction of the screen ( It can also be displayed at the top), and by performing such control, the convenience of the visitor can be enhanced.

  Next, the control unit 31 (control program) transmits the ID information of the exhibition booth 20 selected on the exhibition booth selection screen 51 to the server 40 and requests transmission of the electronic brochure (S106). On the other hand, when the server 40 receives the ID information from the information display device 30, the server 40 identifies the electronic brochure corresponding to the ID information and transmits it to the information display device 30 that is the transmission source of the ID information.

  Next, the control part 31 (control program) receives the electronic brochure corresponding to ID information from the server 40, and displays it on the display part 32 (S107). This screen (electronic pamphlet display screen 52) is configured as shown in FIG. 12, for example, and displays pamphlets and explanatory materials distributed by the selected exhibition booth 20, so that visitors do not obtain materials as paper media. But you can get the information you need.

  Next, when the visitor performs a predetermined operation, the control unit 31 (control program) displays, for example, a storage selection screen 53 as shown in FIG. 13 on the display unit 32 and determines whether or not to save the electronic brochure. The visitor is selected (S108). If the visitor selects save, the displayed electronic brochure is saved in the portable storage medium (S109). If the visitor does not select save, the displayed electronic brochure is discarded (S110).

  Thereafter, the visitor determines whether to end the tour (S111), and when obtaining an electronic brochure of another exhibition booth 20, the visitor returns to S101 and repeats the same processing.

  In this way, each exhibition booth 20 arranged in the exhibition hall is provided with a visible light communication light source 21 that transmits ID information indicating its own booth number as a blinking pattern by visible light communication, and an information display device carried by a visitor. At 30, a plurality of exhibition booths 20 are captured with moving images, each image of the moving images is processed to identify the position of the visible light communication light source 21, and the ID information of the exhibition booth 20 is obtained from the blinking pattern of the visible light communication light source 21. The display booth guidance screen 50 is displayed by specifying the relative position of the information display device with respect to the display booth imaged based on the position of the visible light communication light source 21, ID information, and layout information, and where the desired display booth is located. You can easily figure out if there is.

  In addition, the information display device 30 displays an exhibition booth selection screen 51 that displays a list of exhibition booths 20 in the vicinity of the information display device, and the exhibition booth is based on the ID information corresponding to the exhibition booth 20 selected from the display booth selection screen 51. By acquiring and displaying the 20 electronic brochures, even if the exhibition booth 20 is arranged in proximity, the electronic brochure of the desired exhibition booth 20 can be obtained without acquiring the electronic brochure of the unintended exhibition booth 20.
