[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a vehicle advertising device, a vehicle advertising method, and a program according to the present invention will be described with reference to the drawings.

[0019] FIG. 1 is a diagram showing an overview of a vehicle-mounted advertising system 100 according to the present embodiment. The vehicle-mounted advertising system 100 is a system that displays content including advertisements on an electronic signboard device 200 mounted on a vehicle M and transmits related information about the content to a viewer. The electronic signboard device 200 is installed on the vehicle M so that the display content can be visually recognized from the outside of the vehicle M, and the display content can be arbitrarily changed by setting. For example, FIG. 1 shows a situation in which the vehicle M is running around passersby P1, P2, and P3 while displaying content. The vehicle-mounted advertising system 100 detects viewers of the content from an image captured around the electronic signboard device 200, and provides the detected viewers with related information about the content. For this reason, the vehicle-mounted advertising system 100 includes an imaging device 300 for capturing images of the periphery of the electronic signboard device 200, and a directional communication device 400 for communicating with a terminal device 600 of the viewer. The electronic signboard device 200 may be installed only on one side of the vehicle M, or on both sides. The digital signage device 200 in this embodiment is an example of a "display unit."

[0020] FIG. 2 is a diagram showing a configuration example of the vehicle-mounted advertising system 100 of the present embodiment. The vehicle-mounted advertising system 100 includes a vehicle-mounted advertising device 500 in addition to the above-mentioned electronic signage device 200, imaging device 300, and directional communication device 400. The electronic signage device 200, the imaging device 300, the directional communication device 400, and the vehicle-mounted advertising device 500 are communicably connected to each other by a communication line such as an internal bus or a LAN (Local Area Network). The electronic signage device 200 is a so-called digital signage device, and can display a specified image (including video) at a specified timing. The imaging device 300 is a camera installed at a position and attitude capable of capturing an image of the periphery of the electronic signage device 200. The imaging device 300 is provided to obtain an image for detecting a viewer of the electronic signage device 200, so any camera may be used as long as it can capture an image of a range in which the display content of the electronic signage device 200 can be viewed. For example, when the electronic signboard device 200 is installed on both sides of the vehicle M, the imaging device 300 may be installed separately on each side, or a panoramic camera capable of capturing 360 degrees around the vehicle M may be used. The imaging device 300 outputs the acquired image data to the vehicle advertising device 500 as needed. The imaging device 300 is an example of an "imaging unit."

[0021] The directional communication device 400 is a wireless communication device capable of wireless communication with directivity directed in a predetermined direction. For example, the directional communication device 400 includes a directional antenna and can form the directivity of wireless radio waves in a specific direction with a predetermined beam width by using a beamforming technique. In this embodiment, the directional communication device 400 transmits information specified by the vehicle advertising device 500 with directivity in the direction specified by the vehicle advertising device 500. The directional communication device 400 is an example of a "directional communication unit."

[0022] The vehicle-mounted advertising device 500 is a device that detects a viewer of the electronic signage device 200 from an image (hereinafter referred to as a "peripheral image") captured around the electronic signage device 200, and transmits related information about the content displayed by the electronic signage device 200 to the detected viewer. Specifically, the vehicle-mounted advertising device 500 includes a storage unit 520, an input unit 530, a display unit 540, and a control unit 550.

[0023] The storage unit 520 is configured using a storage device such as an HDD or a flash memory. The storage unit 520 stores various information related to the operation of the vehicle-mounted advertising device 500. For example, the storage unit 520 stores related information to be transmitted to the viewer, content data to be displayed on the electronic signage device 200, and setting information related to the display timing. The content data to be displayed on the electronic signage device 200 and setting information related to the display timing may be stored in the electronic signage device 200, or the same information may be stored in the electronic signage device 200 and the vehicle-mounted advertising device 500.

[0024] The input unit 530 is configured using an input device such as a mouse, a keyboard, a touch panel, etc. The input unit 530 accepts an input operation to the vehicle mounted advertising device 500. The input unit 530 outputs the acquired input information to the control unit 550.

[0025] The display unit 540 is configured using a display device such as a liquid crystal display, an organic EL (Electro-Luminescence) display, a touch panel, etc. The display unit 540 is capable of displaying any information based on an instruction from the control unit 550.

[0026] The control unit 550 is realized by, for example, a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of the components of the control unit 550 may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by cooperation between software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transient storage medium) such as an HDD (Hard Disk Drive) or a flash memory, or may be stored in a removable storage medium (a non-transient storage medium) such as a DVD or a CD-ROM, and installed by mounting the storage medium in a drive device.

[0027] The control unit 550 has a function of controlling the operation of the vehicle advertising device 500. Here, the control function of the control unit 550 includes a function of displaying content, providing related information, and providing corresponding services described later. For example, the control unit 550 includes an acquisition unit 551, a detection unit 552, an estimation unit 553, a position identification unit 554, a transmission unit 555, a determination unit 556, and a service provision unit 557 as functional units that realize these functions.

[0028] The acquisition unit 551 has a function of acquiring a peripheral image from the imaging device 300 and a function of acquiring terminal information from the user's terminal device 600. The acquisition unit 551 records the acquired peripheral image data and terminal information in the storage unit 520. The terminal information will be described later. The acquisition unit 551 also acquires information regarding the running state of the host vehicle M from a vehicle system (not shown) mounted on the host vehicle M. For example, the vehicle system is an in-vehicle ECU (Electronic Control Unit), and the acquisition unit 551 can acquire various vehicle information indicating the running speed and engine state of the host vehicle M from various in-vehicle ECUs mounted on the host vehicle M. The acquisition unit 551 records the acquired vehicle information in the storage unit 520.

[0029] The detection unit 552 recognizes a person from the peripheral image, detects the traveling direction and line of sight of the recognized person, and determines a person whose traveling direction is the same as the traveling direction of the vehicle M and whose line of sight is directed toward the digital signage device 200 for a predetermined time or more as a viewer who is interested in the content. In addition, for example, the detection unit 552 recognizes a person from the peripheral image, detects the traveling direction and movement of the recognized person, and determines a person whose traveling direction is opposite to the traveling direction of the vehicle M and who has performed a look-back movement as a viewer of the content. The detection unit 552 notifies the position identification unit 554 of information about the detected viewer. For example, the detection unit 552 may detect a person whose traveling direction and line of sight have changed from the same direction to the opposite direction as a person who has performed a look-back movement. For example, in the example of FIG. 1, the pedestrian P3 may be detected as a person who has performed a look-back movement.

[0030] The detection unit 552 may determine that the traveling directions of the person and the vehicle M are the same even if they are not completely the same, if the degree of agreement is higher than a predetermined threshold. Similarly, the detection unit 552 may determine that the traveling directions of the person and the vehicle M are the same even if they are not exactly opposite, if the degree of agreement is lower than a predetermined threshold. For example, in this case, the magnitude of the inner product of the vectors of each traveling direction may be set as the degree of agreement of the traveling directions. The detection unit 552 may determine a viewer who is interested in the content based on the level of interest estimated by the estimation unit 553 described later. For example, the detection unit 552 may determine that a viewer whose estimated value of the viewer's level of interest in the content is equal to or higher than a threshold is a viewer who is interested in the content.

[0031] The estimation unit 553 has a function of estimating the level of interest of the detected viewer in the content. For example, the estimation unit 553 may estimate the level of interest of the viewer in the content by quantifying the level of interest using a model that comprehensively considers the detected viewer's traveling direction, line of sight, movement, etc. For example, if the degree of agreement between the viewer's traveling direction and the traveling direction of the vehicle M is x, the degree of agreement between the viewer's line of sight and the position of the digital signage device 200 is y, and an index value of the level of interest estimated from the movement performed by the viewer is z, the level of interest I of the viewer in the content can be calculated using a model of I=ax+by+cz. Here, a, b, and c are weighting coefficients for x, y, and z, respectively, and may be determined by any standard. The weighting coefficients may be determined based on test results, or may be corrected or changed based on operation performance. The estimation unit 553 records information indicating the level of interest of the viewer estimated in this way in the storage unit 520 in association with the position information specified for the viewer.

[0032] The position identification unit 554 can identify the direction in which the viewer is located as viewed from the vehicle M based on the imaging conditions of the imaging device 300 when the surrounding image in which the viewer is detected is captured. For example, if the imaging device 300 is a rotating camera that can change the lens orientation 360 degrees horizontally, if the lens orientation with respect to a reference direction (e.g., the traveling direction of the vehicle M) when the surrounding image is captured is recorded, it is possible to know that the viewer is located in the lens orientation when the surrounding image in which the viewer of the vehicle M is detected is captured. Also, if the lens orientation is fixed, the direction in which the viewer is located can be identified based on the position of the viewer in the surrounding image and with the lens orientation as a reference. Note that, although the case where the direction of the viewer as viewed from the vehicle M is identified has been described as an example here, it is also possible to identify the three-dimensional position of the viewer using information such as a technology for estimating the distance from the image to the subject, highly accurate map information, and position information of the vehicle M. The position identification unit 554 notifies the transmission unit 555 of the position of the viewer identified in this manner. The position identification unit 554 is an example of a "viewer direction recognition unit" and a "viewer position recognition unit."

[0033] The transmitting unit 555 transmits related information about the content to the terminal device 600 of the viewer detected by the detecting unit 552. Specifically, the transmitting unit 555 transmits the related information by directing the directivity of the directional communication device 400 toward the position direction of the viewer identified by the position identifying unit 554. In this way, it is possible to prevent the related information from being transmitted to the terminal device 600 of a person who is not interested in the content. In addition, the transmitting unit 555 has a function of changing the transmission operation of the related information according to the traveling speed of the vehicle M. For example, the transmitting unit 555 transmits the related information when the vehicle M is traveling at a speed equal to or higher than a predetermined speed. In this way, it is possible to prevent unnecessary transmission of the related information when the vehicle M is not traveling for advertising purposes or is stopped.

[0034] The determination unit 556 has a function of determining the travel route of the vehicle M or the display timing of the content on the display unit 540. Specifically, the determination unit 556 determines the travel route of the vehicle M or the display timing of the content on the electronic signage device 200 so as to maximize the level of interest in the content, based on the relationship between the position of the viewer of the content and the level of interest in the content of the viewer estimated by the estimation unit 553.

[0035] The service providing unit 557 provides the above-mentioned corresponding service to a detected viewer when predetermined information related to the display details of the content is input from the terminal device of the viewer. The corresponding service is a predetermined service related to the content or a predetermined service associated with the vehicle M. The corresponding service is not limited to a predetermined service and may be any service as long as it is related to the content or can be provided by a function possessed by the vehicle M.

[0036] FIG. 3 is a flowchart showing an example of the flow of a process (hereinafter referred to as "related information transmission process") in which the vehicle-mounted advertising device 500 transmits related information to the viewer's terminal device 600. Specifically, FIG. 3 shows the flow of the related information transmission process when the vehicle M is traveling for advertising. Also, during the execution of the related information transmission process shown in FIG. 3, it is assumed that a predetermined content is displayed on the electronic signboard device 200. In this situation, first, the acquisition unit 551 acquires a peripheral image of the vehicle M from the imaging device 300 and records it in the storage unit 520 (step S101). Next, the detection unit 552 attempts to detect a viewer who is interested in the content displayed on the electronic signboard device 200 from the peripheral image (step S102), and determines whether or not a viewer has been detected from the peripheral image (step S103).

[0037] Here, if it is determined that a viewer has not been detected, the detection unit 552 ends the related information transmission process. On the other hand, if it is determined that a viewer has been detected, the position identification unit 554 identifies the position of the viewer detected from the surrounding image (step S104). For example, the position identification unit 554 identifies the direction in which the viewer is located as seen from at least the vehicle M. The position identification unit 554 notifies the transmission unit 555 of the identified position of the viewer. Next, the transmission unit 555 transmits the related information via the directional communication device 400, with directivity directed toward the position of the viewer identified by the position identification unit 554 (step S105).

[0038] The flow shown in FIG. 3 shows one cycle of the related information transmission process. By periodically and repeatedly executing such a flow, the vehicle advertising device 500 can detect viewers around the driving position of the vehicle M at any time for the content displayed while the vehicle M is driving, and provide related information to the detected viewers.

[0039] FIG. 4 is a flowchart showing an example of the flow of a process (hereinafter referred to as "compatible service providing process") in which the vehicle-mounted advertising device 500 provides a compatible service to a viewer of a content. Here, for example, a service (hereinafter referred to as "charging service") that provides a viewer with a charging environment for the terminal device 600 will be described as an example of a compatible service that can be provided when the vehicle M is stopped. Note that the compatible service does not necessarily have to be a service that can be provided when the vehicle M is stopped, and may be a service that can be provided while the vehicle M is traveling. Also, as with the related information transmission process in FIG. 3, it is assumed that a predetermined content is displayed on the electronic signboard device 200 during the execution of the compatible service providing process. Also, in FIG. 4, the same processes as those in FIG. 3 are denoted by the same reference numerals as those in FIG. 3, and description thereof will be omitted.

[0040] In this case, when the detection unit 552 detects a viewer of the content in the vehicle advertising device 500, the service providing unit 557 judges whether or not viewer information regarding the use of the corresponding service has been input to the vehicle advertising device 500 (step S201). The viewer information is information for the vehicle advertising device 500 to judge whether or not to provide the corresponding service to the viewer, and is transmitted, for example, from the viewer's terminal device 600. Here, when it is judged that the viewer information has not been input, the service providing unit 557 ends the corresponding service providing process. On the other hand, when it is judged in step S201 that the viewer information has been input, the service providing unit 557 opens the service function to the viewer (step S202) and notifies the viewer's terminal device 600 of the fact.

[0041] FIG. 5 is a diagram showing an example of the corresponding service provision process in the vehicle advertisement system 100 of this embodiment. The corresponding service in FIG. 5 is the above-mentioned charging service. In this case, for example, the vehicle M includes a solar power generator 710 and chargers 720A, 720B, and 720C as power sources when providing the charging service. The solar power generator 710 supplies power to the chargers 720A, 720B, and 720C, and the chargers 720A, 720B, and 720C can charge the devices set therein using the power supplied from the solar power generator 710. Note that the operating states of the chargers 720A, 720B, and 720C are controlled by the service providing unit 557 to be either usable or unusable. The example in FIG. 5 shows a situation in which the terminal devices 600 of viewers B and C are being charged by the chargers 720B and 720C, respectively. Also, in the example in FIG. 5, the viewer A is about to start using the charging service.

[0042] In this case, for example, the vehicle-mounted advertising device 500 detects the viewer A from the surrounding image, and transmits information of a questionnaire for using the charging service as related information to the terminal device 600A of the detected viewer A. The user A inputs an answer to the questionnaire in the terminal device 600A, and the terminal device 600A transmits the answer information to the vehicle-mounted advertising device 500 as viewer information. When the answer information is received by the vehicle-mounted advertising device 500, the service providing unit 557 puts the charger 720A into a usable state (opens the service function) and notifies the terminal device 600A of the same. Upon receiving this notification, the viewer A can use the charging service by setting the terminal device 600A in the charger 720A.

[0043] In this case, the control unit 550 of the vehicle-mounted advertising device 500 may instruct the electronic signage device 200 to display content for each viewer who is using the charging service. For example, the control unit 550 transmits the position information identified for each viewer to the electronic signage device 200. In this case, for example, the electronic signage device 200 may be configured to divide the display area according to the viewer's position and display different content in each divided display area.

[0044] Furthermore, for example, when the control unit 550 has acquired some attribute information or preference information for each viewer, the control unit 550 may transmit the attribute information or preference information for each viewer, in addition to the position information, to the digital signage device 200. In this case, for example, the digital signage device 200 may be configured to display content according to the viewer's attribute or preference in the display area of ​​each viewer.

[0045] FIG. 6 is a flowchart showing an example of a flow of a process (hereinafter referred to as "advertising plan determination process") in which the vehicle advertising device 500 determines the travel route of the vehicle M or the display timing of the content. The advertising plan determination process may be executed while the vehicle M is traveling or while the vehicle is stopped. First, the estimation unit 553 estimates the level of interest of the viewers detected during the content display based on the past performance information of the content display (step S301). For example, when the peripheral images acquired in the past are accumulated in the storage unit 520 as the performance information of the content display, the estimation unit 553 can estimate the level of interest of each viewer in the content based on the traveling direction or line of sight of each viewer recognized from the peripheral image, or the change over time therein.

[0046] Next, the estimation unit 553 analyzes the relationship between the display position of each content and the level of interest of the viewer obtained by displaying the content at the display position based on the level of interest estimated for each viewer, the position information of each viewer, and the display content of the content (step S302). For example, the estimation unit 553 generates a trained model indicating the above-mentioned relationship by machine learning. Next, the determination unit 556 determines the travel route of the vehicle M or the display timing of the content based on the analysis result of the above-mentioned relationship (step S303). Specifically, the determination unit 556 determines the display timing of the travel route or the content so as to maximize the level of interest of the viewer in the content based on the analysis result of the above-mentioned relationship. The estimation unit 553 records information indicating the display timing of the travel route or the content thus determined (hereinafter referred to as "advertising plan information") in the storage unit 520. The control unit 550 may display the advertising plan information on the display unit 540, or may output the advertising plan information to an external device such as a car navigation device (not shown).

[0047] The vehicle advertising device, vehicle advertising method, and program of this embodiment configured as described above include an electronic signage device 200 that is installed on vehicle M so as to be visible from outside the vehicle M and displays content including advertisements, an imaging device 300 that captures peripheral images of the electronic signage device 200, a detection unit 552 that detects viewers who are presumed to be interested in the content based on the peripheral images captured by the imaging device 300, and a transmission unit 555 that transmits related information about the content to the terminal device 600 of the viewer detected by the detection unit 552, making it possible to provide related information to more appropriately selected people.
