Description

[Technical Field]

[0001] FIELD OF THE INVENTION An embodiment of the present invention relates to an elevator system. [Background technology]

[0002] In recent years, elevators equipped with display devices (such as signage) inside the elevator car have become widespread. For example, advertisements are displayed on the signage, and a client who requests the advertisement to be displayed (published) can advertise their desired content to passengers riding in the elevator car. For example, if the client is a store located in a commercial facility where an elevator is installed, the client can advertise their store to passengers riding in the elevator car by requesting that an advertisement related to their store be displayed.

[0003] One of the requests from the client is to know the advertising effectiveness of the advertisements displayed on the signage. One method for estimating the advertising effectiveness of the advertisements displayed on the signage inside the car is to estimate the advertising effectiveness of the specified advertisement using the total display time of the specified advertisement on the signage inside the car and the sales of the store advertised by the specified advertisement.

[0004] However, there is a low correlation between the two factors of the total display time of an advertisement and the sales of the store advertised by the advertisement, and the above method has the problem of not being able to accurately estimate the advertising effectiveness.

[0009] Hereinafter, an embodiment will be described with reference to the drawings. It should be noted that the disclosure is merely an example, and the invention is not limited to the contents described in the following embodiments. Modifications that can be easily conceived by a person skilled in the art are naturally included in the scope of the disclosure. For clearer explanation, the size, shape, etc. of each part may be changed from the actual embodiment and shown schematically in the drawings. In multiple drawings, corresponding elements may be given the same reference numerals, and detailed explanations may be omitted.

[0010] 1 is a diagram showing an example of the schematic configuration of an elevator system according to this embodiment. In this embodiment, an elevator system including an elevator (car) installed in a building (for example, a commercial facility) housing a plurality of stores, and capable of accurately estimating the advertising effectiveness of advertisements promoting stores housed in the commercial facility, will be described.

[0011] A camera 12 is installed above the entrance of the car 11. Specifically, the camera 12 is installed in a panel 11a that covers the upper part of the entrance of the car 11, with the lens portion facing directly downward, or toward the platform or the car.

[0012] The camera 12 has, for example, a wide-angle lens or a fisheye lens, and continuously captures images at several frames per second (for example, 30 frames / second). The camera 12 is activated, for example, when the elevator car 11 arrives at the landing 15 on each floor, and captures images of a predetermined range L1 including the landing side and the elevator side. Note that the installation location of the camera 12 does not have to be above the entrance / exit of the elevator car 11, as long as it can capture images of the entire interior of the elevator car and the predetermined range on the landing side.

[0013] At the landing 15 on each floor, a landing door 14 is installed at the arrival entrance of the car 11. The landing door 14 engages with the car door 13 to open and close when the car 11 arrives. The power source (door motor) is on the car side, and the landing door 14 simply opens and closes following the car door 13.

[0014] The car 11 is provided with an in-car display device 16 (for example, signage). The in-car display device 16 displays, for example, advertisements related to stores located in the commercial facility where the car 11 is installed. A store located in the commercial facility where the car 11 is installed can, for example, request (apply) for the commercial facility to display an advertisement, thereby displaying an advertisement promoting its own store on the in-car display device 16 for a predetermined period (during the advertisement display period).

[0015] Each image (video) continuously captured by the camera 12 is analyzed in real time by the image processing device 20. For convenience, the image processing device 20 is shown removed from the car 11 in Fig. 1, but in reality, the image processing device 20 is housed in the headboard 11a together with the camera 12.

[0016] The elevator control device 30 is composed of a computer equipped with a CPU, a ROM, a RAM, etc. The elevator control device 30 controls the raising and lowering operation of the car 11 and the operation of various devices installed in the car 11.

[0017] The elevator control device 30 includes a door opening / closing control unit 31. The door opening / closing control unit 31 controls the opening and closing of the car door 13 when the car 11 arrives at the landing 15. In detail, the door opening / closing control unit 31 opens the car door 13 when the car 11 arrives at the landing 15, and closes the door after a predetermined time has elapsed, or closes the door in response to pressing a door closing button provided on the car 11.

[0018] The cloud server 40 is a server that is communicatively connected to the image processing device 20 and stores user information registered by the image processing device 20. When the elevator system according to this embodiment includes a plurality of cars 11, the cloud server 40 aggregates (stores) the user information registered by the image processing device 20 installed in each of the plurality of cars 11.

[0019] The user information is information about a user who has used the elevator car 11, and includes characteristic information indicating the characteristics of the user, linked with store information indicating a store that was advertised by an advertisement that the user had previously noticed via the elevator car interior display device 16 and the floor on which the store is located. In this embodiment, it is assumed that the characteristic information is a facial image of the user, but the characteristic information may be information other than the above-mentioned facial image as long as it can uniquely identify the user.

[0020] Here, a specific example of user information will be described with reference to FIG. 2 shows that a user uniquely identified by the feature information "face image I1" has previously paid attention to an advertisement advertising "Store X" located on the "third floor" of a commercial facility. In other words, it shows that an advertisement advertising "Store X" located on the "third floor" of a commercial facility has previously been the advertisement that a user uniquely identified by the feature information "face image I1" has previously paid attention to.

[0021] 2 indicates that a user uniquely identified by the feature information "facial image I2" has previously paid attention to an advertisement advertising "Store X" located on the "third floor" of a commercial facility and an advertisement advertising "Store Y" located on the "fifth floor" of the commercial facility. In other words, the advertisements that a user uniquely identified by the feature information "facial image I2" has previously paid attention to are an advertisement advertising "Store X" located on the "third floor" of a commercial facility and an advertisement advertising "Store Y" located on the "fifth floor" of the commercial facility.

[0022] 2 shows that the user uniquely identified by the feature information "face image I3" has not paid attention to any advertisements in the past. A state in which no store information is linked to feature information, as in the user information 103, can occur when, for example, the user has never paid attention to an advertisement displayed on the in-car display device 16, when the user information is newly registered in the cloud server 40, or when the store information included in the user information is reset.

[0023] It is desirable to reset the store information included in the user information at predetermined intervals (for example, every time an advertisement displayed (published) on the car interior display device 16 is switched to another advertisement). This makes it possible to prevent a user who gets off at a floor corresponding to an advertisement after a considerable amount of time has passed since the end of the advertisement display period on the car interior display device 16, regardless of whether they saw the advertisement, from being judged to have gotten off due to the advertisement. In other words, it is possible to improve the accuracy of estimating the effectiveness of the advertisement.

[0024] 1, a detailed description will be given of the image processing device 20. The image processing device 20 includes a storage unit 21 and a processing unit 22.

[0025] The storage unit 21 is composed of a memory device such as a RAM. The storage unit 21 sequentially stores images captured by the camera 12. The storage unit 21 has a buffer area for temporarily storing data necessary for processing by the processing unit 22. The storage unit 21 may store images that have been subjected to preprocessing such as distortion correction, enlargement / reduction, and partial cropping as preprocessing of the images captured by the camera 12.

[0026] The storage unit 21 also stores advertising effectiveness information that indicates the advertising effectiveness of the advertisement displayed on the car interior display device 16. Details of the advertising effectiveness information will be described later, and therefore a detailed description thereof will be omitted here.

[0027] The processing unit 22 uses images captured by the camera 12 to detect users in the elevator 11, and performs an advertising effectiveness determination process for the detected users to determine (estimate) the advertising effectiveness of advertisements that the users have previously paid attention to.

[0028] 1, the processing unit 22 includes a user detection unit 23, an advertising effectiveness determination unit 24, a user information registration unit 25, and an advertising effectiveness information provision unit 26. Note that each of the units 23 to 26 included in the processing unit 22 may be realized by a CPU (not shown) provided in the image processing device 20 executing a program (i.e., software), or may be realized by hardware such as an integrated circuit (IC), or may be realized by a combination of software and hardware.

[0029] The user detection unit 23 detects users in the car 11 or at the landing 15 using the image captured by the camera 12. Specifically, as shown in Fig. 3, the user detection unit 23 divides the image captured by the camera 12 into a number of blocks, and performs a motion detection process to detect blocks with movement (moving blocks) from among the blocks by focusing on changes in color information of each block (for example, changes in brightness value). According to this motion detection process, users appearing in the image are detected as a collection of moving blocks.

[0030] Note that the user detection unit 23 may detect users not by the above-described motion detection process but by, for example, SSD (Single Shot Multibox Detector), which is one of the image recognition methods using supervised learning. In this case, the user detection unit 23 can efficiently detect users who are in the car 11 or the hall 15, including their positions, from newly captured images by learning images of users who are in the car 11 or the hall 15 in advance as training data.

[0031] The advertising effectiveness determination unit 24 executes an advertising effectiveness determination process for each user (hereinafter referred to as a target user) detected by the user detection unit 23. The advertising effectiveness determination process will be described in detail below.

[0032] First, the advertising effectiveness determination unit 24 determines whether or not user information corresponding to the target user is registered (stored) in the cloud server 40. Specifically, the advertising effectiveness determination unit 24 performs a matching process in which it compares (matches) the facial image of the target user with facial images of users indicated by feature information included in each of a large number of pieces of user information stored in the cloud server 40, and determines whether or not user information corresponding to the target user is registered in the cloud server 40.

[0033] If the result of the above-mentioned matching process indicates that user information corresponding to the target user is registered in the cloud server 40, the advertising effectiveness determination unit 24 determines, based on the image taken by the camera 12, whether the floor where the target user will disembark this time is the floor where the store (hereinafter referred to as the target store) indicated by the store information included in the user information corresponding to the target user is located.

[0034] Here, the advertising effectiveness determination unit 24 determines whether the floor where the target user will disembark this time is the floor where the target store is located, but this is not limited to this, and the advertising effectiveness determination unit 24 may also determine whether the destination floor registered by the target user this time is the floor where the target store is located.

[0035] If it is determined as a result of this determination that the floor where the target user will disembark this time is the floor where the target store is located (or if it is determined that the destination floor registered this time by the target user is the floor where the target store is located), the advertising effectiveness determination unit 24 determines that the advertisement promoting the target store was effective.

[0036] On the other hand, if the result of the above judgment is that the floor where the target user will disembark this time is not the floor where the target store is located (or if it is determined that the destination floor registered by the target user this time is not the floor where the target store is located), the advertising effectiveness judgment unit 24 will judge that the advertisement promoting the target store was ineffective.

[0037] Based on the results of the above-mentioned determination, the advertising effectiveness determination unit 24 counts the number of times the advertising effectiveness of the advertisement promoting the target store has been determined, the number of times the advertisement has been determined to have advertising effectiveness, and the number of times the advertisement has been determined to have advertising effectiveness. Information indicating each of the counted numbers is stored in the storage unit 21 as advertising effectiveness information indicating the advertising effectiveness of the advertisement promoting the target store. Note that the form of the advertising effectiveness information is not limited to this, and any form may be used as long as it is possible to determine the advertising effectiveness of the advertisement promoting the target store.

[0038] Here, a specific example of the advertising effectiveness information will be described with reference to FIG. As shown in FIG. 4, the advertising effectiveness information is information that links store information indicating a store that has requested to post an advertisement with various information regarding the advertising effectiveness of advertisements that advertised the store indicated by the store information. According to the advertising effectiveness information 201 shown in FIG. 4, the number of times (total number) that the advertising effectiveness of an advertisement advertising "Store X" located on the "3rd floor" has been determined is "10 times," of which the number of times that the advertisement was determined to be effective is "7 times," and the number of times that the advertisement was determined to be ineffective is "3 times." In other words, Store X that has requested to post an advertisement can know that its advertisement was effective for 70% of users and ineffective for 30% of users. Such advertising effectiveness information is stored in the memory unit 21 for each store that has requested to post an advertisement.

[0039] Returning to Figure 1 again. When the result of the above-described matching process by the advertising effectiveness determination unit 24 indicates that user information corresponding to the target user is not registered in the cloud server 40, the user information registration unit 25 newly registers user information corresponding to the target user in the cloud server 40. More specifically, the user information registration unit 25 newly registers user information including feature information indicating a facial image of the target user in the cloud server 40. This makes it possible to register in the cloud server 40 user information in which no store information is linked to the feature information, such as the user information 103 shown in FIG. 2, for example.

[0040] In addition, the user information registration unit 25 determines, based on the image captured by the camera 12, whether or not the target user paid attention to the advertisement displayed on the car interior display device 16 before getting off the car 11.

[0041] If it is determined as a result of this determination that the target user paid attention to the advertisement, the user information registration unit 25 updates the user information corresponding to the target user. Specifically, the user information registration unit 25 links the store information corresponding to the advertisement that the target user paid attention to with the characteristic information included in the user information corresponding to the target user. In this way, the next time the target user gets on the elevator 11, it is possible to determine the advertising effectiveness of the advertisement corresponding to the currently linked store information.

[0042] The advertising effectiveness information providing unit 26 provides (sends) advertising effectiveness information indicating the advertising effectiveness of the advertisement to a store that has requested the in-car interior display device 16 to post an advertisement to promote its own store (for example, an email address set as a contact point by the store).

[0043] Next, an example of the operation of the elevator system according to this embodiment will be described with reference to the flowchart in Fig. 5. Note that, in this description, it is assumed that the image processing device 20 acquires images taken by the camera 12 in time series and stores these acquired images in the storage unit 21 one by one.

[0044] When the car 11 arrives at an arbitrary floor (Yes in step S1), the door opening / closing control unit 31 of the elevator control device 30 opens the car door 13 (step S2).

[0045] When the car door 13 opens, the user detection unit 23 of the image processing device 20 detects the presence or absence of users in the car 11 and at the landing 15 based on the image captured by the camera 12. Here, it is assumed that a group of moving blocks (i.e., users) is detected by the user detection unit 23. The subsequent processing is executed for each user (i.e., target user) detected by the user detection unit 23.

[0046] First, the advertising effectiveness determination unit 24 determines whether or not user information corresponding to the target user is registered in the cloud server 40. Specifically, the advertising effectiveness determination unit 24 matches the facial image of the target user with facial images of users indicated by feature information included in each of a large number of pieces of user information stored in the cloud server 40, and determines whether or not user information corresponding to the target user is registered in the cloud server 40 (step S3).

[0047] If it is determined in the processing of step S3 that user information corresponding to the target user is not registered in the cloud server 40 (No in step S3), the user information registration unit 25 newly registers user information including feature information indicating the facial image of the target user in the cloud server 40 (step S4), and executes the processing of step S9 described below.

[0048] On the other hand, if it is determined in the processing of step S3 that the user information corresponding to the target user is registered in the cloud server 40 (Yes in step S3), the advertising effectiveness determination unit 24 determines whether or not the user information corresponding to the target user includes one or more pieces of store information (step S5). Note that if it is determined in the processing of step S5 that the user information corresponding to the target user does not include one or more pieces of store information, that is, that the user information corresponding to the target user does not include any store information (No in step S5), the processing of step S9, which will be described later, is executed.

[0049] On the other hand, if it is determined in the processing of step S5 that the user information corresponding to the target user includes one or more store information items (Yes in step S5), the advertising effectiveness determination unit 24 determines, based on the image taken by the camera 12, whether the floor where the target user will disembark this time is one of the floors occupied by the stores (i.e., the target stores) indicated by one or more store information items included in the user information corresponding to the target user (step S6).

[0050] In the processing of step S6, if it is determined that the floor where the target user disembarked this time is the floor where the specified target store is located (Yes in step S6), the advertising effectiveness determination unit 24 determines that the advertisement promoting the specified target store was effective (step S7).

[0051] In this case, the advertising effectiveness determination unit 24 counts the number of times that the advertising effectiveness has been determined for an advertisement that advertised a predetermined target store by adding 1 to the number of times that the advertising effectiveness has been determined, and also counts the number of times that the advertising effectiveness has been determined. Note that if the user information corresponding to the target user includes multiple store information, the advertising effectiveness determination unit 24 determines that the advertising effectiveness has been ineffective for an advertisement that advertised a target store other than the predetermined target store that corresponds to the floor where the target user currently gets off. In this case, the advertising effectiveness determination unit 24 counts the number of times that the advertising effectiveness has been determined for an advertisement that advertised a target store other than the predetermined target store by adding 1 to the number of times that the advertising effectiveness has been determined, and also counts the number of times that the advertising effectiveness has been determined to be ineffective.

[0052] On the other hand, if it is determined in the processing of step S6 that the floor where the target user disembarked this time is not one of the floors where the target store is located (No in step S6), the advertising effectiveness determination unit 24 determines that the advertisement promoting the target store was ineffective (step S8).

[0053] In this case, the advertising effectiveness determination unit 24 counts the number of times that the advertising effectiveness has been determined for the advertisement promoting the target store by adding 1, and also counts the number of times that the advertising effectiveness has been determined to be ineffective by adding 1.

[0054] According to the processing of steps S7 and S8 described above, it is possible to compile advertising effectiveness information indicating the advertising effectiveness of advertisements promoting the target store, as shown in FIG. 4, for example. The advertising effectiveness information is stored in the storage unit 21 and is updated each time the processing of steps S7 and S8 described above is executed. The compiled advertising effectiveness information is provided to the store that requested the advertisement to be published, for example, when the advertisement publication period ends. This allows the store that requested the advertisement to be published to know the advertising effectiveness of the advertisement promoting its own store.

[0055] Next, the user information registration unit 25 determines whether or not the target user has been paying attention to the advertisement displayed on the car interior display device 16 until the target user gets off the car 11 this time (step S9). Whether or not the target user has been paying attention to the advertisement is determined, for example, based on the amount of time (viewing time) that the target user has been looking at the advertisement displayed on the car interior display device 16 until the target user gets off the car 11 this time. The user information registration unit 25 determines that the target user has been paying attention to the advertisement if the viewing time of the advertisement by the target user is equal to or longer than a predetermined time, and determines that the target user has not been paying attention to the advertisement if the viewing time of the advertisement by the target user is shorter than a predetermined time.

[0056] If it is determined in the process of step S9 that the target user paid attention to the advertisement (Yes in step S9), the user information registration unit 25 updates the user information corresponding to the target user so as to link the store information corresponding to the advertisement that the target user paid attention to with the characteristic information included in the user information corresponding to the target user (step S10), and the elevator system ends this series of processes. Note that if it is determined in the process of step S9 that the target user did not pay attention to the advertisement (No in step S9), the user information corresponding to the target user is not updated, and this series of processes ends.

[0057] As described above, the series of processes described above are executed for each of the target users detected by the user detection unit 23. This makes it possible to determine (estimate) the advertising effectiveness of advertisements that each user riding in the car 11 has previously focused on.

[0058] As described above, the elevator system according to this embodiment includes the cloud server 40 that stores user information including, in association with the user's characteristic information, store information indicating a store advertised in an advertisement that the user previously looked at via the car interior display device 16 and the floor where the store is located, and the advertisement effectiveness determination unit 24 that determines the advertisement effectiveness of the advertisement based on whether the floor where the user is currently getting off is the floor where the store indicated by the store information is located. In this way, the elevator system according to this embodiment determines the advertisement effectiveness of the advertisement displayed on the car interior display device 16 based on two highly related elements, the floor where the store advertised in an advertisement that the user previously looked at and the floor where the user is currently getting off, and therefore, it is possible to accurately estimate the advertisement effectiveness of the advertisement.

[0059] For example, a method has already been devised for estimating the advertising effectiveness of an advertisement based on the total display time of the advertisement displayed on a display device installed in a car and the sales of the store advertised by the advertisement. However, this method does not take into consideration whether the passengers in the car paid attention to the advertisement displayed on the display device, and estimates the advertising effectiveness of the advertisement based simply on two factors that have little correlation, namely the total display time of the advertisement and the sales of the store advertised by the advertisement, and therefore is unable to accurately estimate the advertising effectiveness.

[0060] In contrast, the elevator system of this embodiment, as described above, estimates the advertising effectiveness of the advertisement based on two highly related elements: the floor where the store advertised in the advertisement that the user previously focused on is located, and the floor where the user will be getting off this time. Therefore, it is possible to estimate the advertising effectiveness more accurately than the above-mentioned method.

[0061] Another method for estimating advertising effectiveness has been devised, which estimates the advertising effectiveness of an advertisement displayed on a display device equipped with a touch panel function installed inside a car based on the user's operation history on the display device. However, this method has the problem that it requires the user to operate the display device (in other words, it requires the user's cooperation), which is time-consuming from the user's perspective. Furthermore, with this method, the time and effort required may prevent active cooperation from users, and there is a possibility that a sufficient amount of operation history may not be collected to estimate advertising effectiveness.

[0062] In contrast, the elevator system according to this embodiment is useful in that it can estimate the effectiveness of advertising without requiring any special operations or actions from users riding in the elevator car 11.

[0063] Furthermore, if user information corresponding to a user detected by the user detection unit 23 is not registered in the cloud server 40, the elevator system according to this embodiment automatically registers the user information corresponding to the user in the cloud server 40. The elevator system according to this embodiment also determines whether the user detected by the user detection unit 23 paid attention to the advertisement displayed on the in-car display device 16, and automatically updates the user information corresponding to the user based on the result of this determination. In other words, the elevator system according to this embodiment can automatically register and update information necessary to estimate the effectiveness of advertising, thereby reducing the burden on the operator of the system.

[0064] Furthermore, unlike general methods for estimating advertising effectiveness, the elevator system according to this embodiment can estimate advertising effectiveness specifically within the environment inside the elevator car 11.

[0065] In the present embodiment described above, the advertisements displayed on the car interior display device 16 are advertisements related to stores located in the commercial facility in which the elevator car 11 is installed. However, the advertisements displayed on the car interior display device 16 may also be advertisements for promoting an event being held on a specific floor of the commercial facility.

[0066] Furthermore, in this embodiment, the car interior display device 16 displays advertisements for stores located in the commercial facility where the elevator car 11 is installed, but the car interior display device 16 may also display advertisements for stores located on a floor other than the target user's current destination floor, and not display advertisements for stores located on the current destination floor. In this case, when the target user registers a destination floor, the elevator control device 30 controls the car interior display device 16 to deliver advertisements for stores located on a floor other than the destination floor.

[0067] Furthermore, in this embodiment, the user information registration unit 25 determines whether or not the target user has been paying attention to the advertisement displayed on the car interior display device 16 until the time the target user disembarked from the car 11 this time, based on the image captured by the camera 12. However, this is not limited to this, and the elevator system may further include a camera other than the camera 12 near the car interior display device 16, and the user information registration unit 25 may determine whether or not the target user has been paying attention to the advertisement displayed on the car interior display device 16, based on the image captured by that camera.

[0068] According to the embodiment described above, it is possible to provide an elevator system that can accurately estimate the advertising effectiveness of advertisements displayed on a display device installed inside an elevator car.

[0069] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the inventions and their equivalents as defined in the claims.
