Description

Technical Field

[0001] Embodiments of the present invention relate to an elevator system.

Background Art

[0002] In recent years, elevators equipped with display devices (such as signage) inside the car have become widely popular. For example, advertisements are displayed on the signage, and the requester who requests the display (publication) of the advertisement can promote the content they desire to the users who board the elevator. For example, if the requester is a store located in a commercial facility where the elevator is installed, the requester can promote their store to the users who board the elevator by requesting the display of an advertisement related to their store.

[0003] By the way, among the requests from the above-mentioned requesters, there is a request to know the advertising effect of the advertisements displayed on the signage. As one method of estimating the advertising effect of the advertisements displayed on the signage inside the car, there is a method of estimating the advertising effect of a predetermined advertisement by using the total display time of the predetermined advertisement displayed on the signage inside the car and the sales of the store promoted by the predetermined advertisement.

[0004] However, the correlation between the two elements of the total display time of the advertisement and the sales of the store promoted by the advertisement is low, and there is a problem that the advertising effect cannot be accurately estimated by the above method.

Embodiment for Carrying Out the Invention

[0009] Hereinafter, embodiments 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 by the contents described in the following embodiments. Modifications that can be easily conceived by those skilled in the art are naturally included in the scope of the disclosure. For the sake of clarity in the description, in the drawings, the sizes, shapes, etc. of each part may be changed with respect to the actual implementation mode and represented schematically. In a plurality of drawings, the same reference numerals may be assigned to corresponding elements, and detailed descriptions may be omitted.

[0010] FIG. 1 is a diagram showing a schematic configuration example 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) in which a plurality of stores are located will be described, which is an elevator system capable of accurately estimating the advertisement effect of an advertisement for promoting the stores located in the commercial facility.

[0011] A camera 12 is installed above the entrance and exit of the car 11. Specifically, the camera 12 is installed with its lens portion downward or toward the landing side or the car side inside a curtain plate 11a that covers the upper part of the entrance and exit of the car 11.

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

[0013] On the landing 15 of each floor, a landing door 14 is installed at the arrival opening of the car 11. The landing door 14 engages with the car door 13 when the car 11 arrives and performs an opening / closing operation. Note that the power source (door motor) is on the car side, and the landing door 14 only opens and closes following the car door 13.

[0014] In the car 11, a car interior display device 16 (for example, signage) is provided. On the car interior display device 16, for example, advertisements related to the stores in the commercial facility where the car 11 is installed are displayed. The stores in the commercial facility where the car 11 is installed can, for example, request (apply) to publish an advertisement in the commercial facility, and display an advertisement for promoting their own stores on the car interior display device 16 during a predetermined period (during the advertisement publication period).

[0015] Each image (video) continuously captured by the camera 12 is analyzed and processed in real time by the image processing device 20. In FIG. 1, for the sake of convenience, the image processing device 20 is taken out of the car 11 and shown, but actually, the image processing device 20 is housed together with the camera 12 inside the bulkhead 11a.

[0016] The elevator control device 30 consists of a computer equipped with a CPU, ROM, RAM, etc. The elevator control device 30 controls the ascending / descending 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. Specifically, the door opening / closing control unit 31 opens the car door 13 when the car 11 arrives at the landing 15, closes the door after a predetermined time has elapsed, or closes the door in response to the depression of a door closing button provided on the car 11.

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

[0019] The user information is information regarding the user who uses the car 11, and includes the feature information indicating the characteristics of the user and the store information indicating the store that was advertised by the advertisement that the user has paid attention to in the past via the in-car display device 16 and the floor on which the store is located, linked together. In the present embodiment, it is assumed that the feature information is the face image of the user, but the feature information may be other than the above-described face image as long as it can uniquely identify the user.

[0020] Here, with reference to FIG. 2, a specific example of the user information will be described. According to the user information 101 shown in FIG. 2, it is shown that the user uniquely identified by the feature information "face image I1" has paid attention to an advertisement for "Store X" located on the "3rd floor" of a commercial facility in the past. In other words, it is shown that there is an advertisement for "Store X" located on the "3rd floor" of a commercial facility as an advertisement that the user uniquely identified by the feature information "face image I1" has paid attention to in the past.

[0021] Also, according to the user information 102 shown in FIG. 2, it is shown that the user uniquely identified by the feature information "face image I2" has previously paid attention to an advertisement for "Store X" located on the "3rd floor" of the commercial facility and an advertisement for "Store Y" located on the "5th floor" of the commercial facility. In other words, as advertisements that the user uniquely identified by the feature information "face image I2" has previously paid attention to, there are an advertisement for "Store X" located on the "3rd floor" of the commercial facility and an advertisement for "Store Y" located on the "5th floor" of the commercial facility.

[0022] Furthermore, according to the user information 103 shown in FIG. 2, it is shown that the user uniquely identified by the feature information "face image I3" has no advertisements that the user has previously paid attention to. A state where no store information is associated with the feature information, such as in the user information 103, can occur, for example, when the user has never paid attention to the advertisements displayed on the car interior 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] Note that it is desirable that the reset of the store information included in the user information be performed at predetermined intervals (for example, at the timing of switching the advertisement displayed (posted) on the car interior display device 16 to another advertisement). According to this, after a considerable amount of time has passed since the end of the advertisement posting period on the car interior display device 16, it is possible to prevent a user who has gotten off at the floor corresponding to the advertisement from being determined to be due to the advertisement, regardless of whether the user has seen the advertisement. That is, the estimation accuracy of the advertisement effect can be improved.

[0024] Returning to FIG. 1 again, the image processing device 20 will be described in detail. 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 the images captured by the camera 12. The storage unit 21 has a buffer area for temporarily storing data necessary for the processing of the processing unit 22. In the storage unit 21, images subjected to processing such as distortion correction, enlargement / reduction, and partial cutting may be stored as pre-processing for the images captured by the camera 12.

[0026] Also, the storage unit 21 stores advertisement effect information indicating the advertisement effect of the advertisement displayed on the car interior display device 16. Since the details of the advertisement effect information will be described later, a detailed description thereof is omitted here.

[0027] The processing unit 22 uses the image captured by the camera 12 to detect a user inside the car 11, and executes an advertisement effect determination process for determining (estimating) the advertisement effect of the advertisement that the detected user has paid attention to in the past.

[0028] As shown in FIG. 1, the processing unit 22 includes a user detection unit 23, an advertisement effect determination unit 24, a user information registration unit 25, and an advertisement effect information providing unit 26. 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 (that is, software), or may be realized by hardware such as an IC (Integrated Circuit), or may be realized by a combination of software and hardware.

[0029] The user detection unit 23 uses the image captured by the camera 12 to detect a user inside the car 11 or at the platform 15. Specifically, as shown in FIG. 3, the user detection unit 23 divides the image captured by the camera 12 into a number of blocks, focuses on the change in the color information of each block (for example, the change in the luminance value), and executes a motion detection process for detecting a moving block (motion block) from among the blocks. According to this motion detection process, the user reflected in the image is detected as an aggregate of motion blocks.

[0030] Note that the user detection unit 23 may detect the user 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 a user in the car 11 or the landing 15, including the position thereof, from the newly captured images by pre-learning an image in which the user in the car 11 or the landing 15 is reflected as teacher data.

[0031] The advertisement effect determination unit 24 executes an advertisement effect determination process for each of the users detected by the user detection unit 23 (hereinafter referred to as target users). Hereinafter, the advertisement effect determination process will be described in detail.

[0032] First, the advertisement effect determination unit 24 determines whether user information corresponding to the target user is registered (stored) in the cloud server 40. Specifically, the advertisement effect determination unit 24 performs a comparison (matching) between the face image of the target user and the face images of the users indicated by the feature information included in a large number of pieces of user information stored in the cloud server 40, and executes a matching process for determining whether user information corresponding to the target user is registered in the cloud server 40.

[0033] When the result of the above-described matching process indicates that user information corresponding to the target user is registered in the cloud server 40, the advertisement effect determination unit 24 determines, based on the image captured by the camera 12, whether the current getting-off floor of the target user is the occupancy floor of a store (hereinafter referred to as target store) indicated by the store information included in the user information corresponding to the target user.

[0034] Here, it is assumed that the advertisement effect determination unit 24 determines whether the current getting-off floor of the target user is the occupied floor of the target store. However, it is not limited to this. The advertisement effect determination unit 24 may determine whether the destination floor registered this time by the target user is the occupied floor of the target store.

[0035] As a result of this determination, if it is determined that the current getting-off floor of the target user is the occupied floor of the target store (or if it is determined that the destination floor registered this time by the target user is the occupied floor of the target store), the advertisement effect determination unit 24 determines that the advertisement promoting the target store has an advertisement effect.

[0036] On the other hand, as a result of the above determination, if it is determined that the current getting-off floor of the target user is not the occupied floor of the target store (or if it is determined that the destination floor registered this time by the target user is not the occupied floor of the target store), the advertisement effect determination unit 24 determines that the advertisement promoting the target store has no advertisement effect.

[0037] Based on the result of the above determination, the advertisement effect determination unit 24 counts the number of times of determining the advertisement effect of the advertisement promoting the target store, the number of times of determining that the advertisement has an advertisement effect, and the number of times of determining that the advertisement has no advertisement effect, respectively. The information indicating each counted number is stored in the storage unit 21 as advertisement effect information indicating the advertisement effect of the advertisement promoting the target store. Note that the form of the advertisement effect information is not limited to this, and any form may be used as long as it can show the advertisement effect of the advertisement promoting the target store.

[0038] Here, with reference to FIG. 4, a specific example of the advertisement effect information will be described. As shown in FIG. 4, the advertisement effect information is information in which store information indicating the store that requested the advertisement placement is linked to various information regarding the advertisement effect of the advertisement that promoted the store indicated by the store information. According to the advertisement effect information 201 shown in FIG. 4, the number of times (total number) of determining the advertisement effect of the advertisement that promoted "Store X" occupying the "3rd floor" is "10 times", and among them, the number of times determined to have an advertisement effect is "7 times", and the number of times determined to have no advertisement effect is shown to be "3 times". That is, Store X that requested the advertisement placement can know that its advertisement was effective for 70% of the users and not effective for 30% of the users. Such advertisement effect information is stored in the storage unit 21 for each store that requested the advertisement placement.

[0039] Return to FIG. 1 again. When the result of the above-described matching process by the advertisement effect determination unit 24 indicates that the user information corresponding to the target user is not registered in the cloud server 40, the user information registration unit 25 newly registers the 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 the face image of the target user in the cloud server 40. According to this, for example, user information in a state where no store information is linked to the feature information, such as the user information 103 shown in FIG. 2, can be registered in the cloud server 40.

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

[0041] As a result of this determination, if it is determined that the target user was paying 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 associates the store information corresponding to the advertisement that the target user was paying attention to with the feature information included in the user information corresponding to the target user. According to this, when the target user next boards the car 11, it is possible to determine the advertising effect of the advertisement corresponding to the store information linked this time.

[0042] The advertising effect information providing unit 26 provides (transmits) advertising effect information indicating the advertising effect of the advertisement to the store (for example, the email address etc. set as the contact by the store) that requested the posting of the advertisement for promoting its own store on the car interior display device 16.

[0043] Next, with reference to the flowchart of FIG. 5, an example of the operation of the elevator system according to the present embodiment will be described. Here, it is described assuming that the image processing device 20 acquires the images captured by the camera 12 in time series and sequentially stores these acquired images in the storage unit 21.

[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 the landing 15 based on the images captured by the camera 12. Here, it is assumed that a set of motion blocks (that is, users) is detected by the user detection unit 23. The subsequent processing is executed for each of the users detected by the user detection unit 23 (that is, the target users).

[0046] First, the advertisement effect determination unit 24 determines whether user information corresponding to the target user is registered in the cloud server 40. Specifically, the advertisement effect determination unit 24 performs matching between the face image of the target user and the face images of the users indicated by the feature information respectively included in a large number of user information stored in the cloud server 40, and determines whether the user information corresponding to the target user is registered in the cloud server 40 (step S3).

[0047] In the process of step S3, if it is determined that the 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 the feature information indicating the face image of the target user in the cloud server 40 (step S4), and executes the process of step S9 described later.

[0048] On the other hand, in the process of step S3, if it is determined that the user information corresponding to the target user is registered in the cloud server 40 (Yes in step S3), the advertisement effect determination unit 24 determines whether one or more store information is included in the user information corresponding to the target user (step S5). In the process of step S5, if it is determined that one or more store information is not included in the user information corresponding to the target user, that is, no store information is included in the user information corresponding to the target user (No in step S5), the process of step S9 described later is executed.

[0049] On the other hand, in the process of step S5, if it is determined that one or more store information is included in the user information corresponding to the target user (Yes in step S5), the advertisement effect determination unit 24 determines, based on the image captured by the camera 12, whether the current getting-off floor of the target user is any of the occupancy floors of the stores (i.e., target stores) respectively indicated by one or more store information included in the user information corresponding to the target user (step S6).

[0050] In the process of step S6, if it is determined that the current alighting floor of the target user is the floor where the predetermined target store is located (Yes in step S6), the advertisement effect determination unit 24 determines that the advertisement that promoted the predetermined target store had an advertisement effect (step S7).

[0051] In this case, the advertisement effect determination unit 24 adds 1 to the number of times the advertisement effect has been determined for the advertisement that promoted the predetermined target store and counts it, and adds 1 to the number of times it has been determined that there is an advertisement effect and counts it. If a plurality of store information is included in the user information corresponding to the target user, the advertisement effect determination unit 24 determines that there is no advertisement effect for the advertisement that promoted the target store other than the predetermined target store corresponding to the current alighting floor of the target user. In this case, the advertisement effect determination unit 24 adds 1 to the number of times the advertisement effect has been determined for the advertisement that promoted the target store other than the predetermined target store and counts it, and adds 1 to the number of times it has been determined that there is no advertisement effect and counts it.

[0052] On the other hand, in the process of step S6, if it is determined that the current alighting floor of the target user is not any of the floors where the target store is located (No in step S6), the advertisement effect determination unit 24 determines that there is no advertisement effect for the advertisement that promoted the target store (step S8).

[0053] In this case, the advertisement effect determination unit 24 adds 1 to the number of times the advertisement effect has been determined for the advertisement that promoted the target store and counts it, and adds 1 to the number of times it has been determined that there is no advertisement effect and counts it.

[0054] According to the processes of step S7 and step S8 described above, for example, as shown in FIG. 4, it is possible to aggregate advertisement effect information indicating the advertisement effect of the advertisement that promoted the target store. The advertisement effect information is stored in the storage unit 21 and is updated each time the processes of step S7 and step S8 described above are executed. The aggregated advertisement effect information is provided to the store that requested the advertisement posting, for example, at the timing when the advertisement posting period ends. According to this, the store that requested the advertisement posting can know the advertisement effect of the advertisement that promoted its own store.

[0055] Subsequently, the user information registration unit 25 determines whether the target user paid 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 the user paid attention to the advertisement is determined based on, for example, the time (viewing time) that the target user watched 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 user paid attention to the advertisement when the viewing time of the advertisement by the target user is equal to or longer than a predetermined time, and determines that the user did not pay attention to the advertisement when the viewing time of the advertisement by the target user is less than the predetermined time.

[0056] In the process of step S9, when it is determined that the target user paid attention to the advertisement (Yes in step S9), the user information registration unit 25 updates the user information included in the user information corresponding to the target user so as to associate the store information corresponding to the advertisement to which the user paid attention with the characteristic information (step S10), and the elevator system ends the series of processes here. In the process of step S9, when it is determined 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 the series of processes here 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. According to this, it is possible to determine (estimate) the advertising effect for each of the users who board the car 11 with respect to the advertisements that the users have paid attention to in the past.

[0058] As described above, the elevator system according to the present embodiment stores user information including linking the characteristic information of the user, the store advertised by the advertisement that the user has paid attention to in the past via the car interior display device 16, and the store information indicating the occupied floor of the store, and a cloud server 40 that stores the user information, and an advertisement effect determination unit 24 that determines the advertisement effect of the advertisement based on whether the current disembarkation floor of the user is the occupied floor of the store indicated by the store information. In this way, the elevator system according to the present embodiment determines the advertisement effect of the advertisement displayed on the car interior display device 16 based on two highly relevant elements: the occupied floor of the store advertised by the advertisement that the user has paid attention to in the past and the current disembarkation floor of the user. Therefore, it is possible to accurately estimate the advertisement effect of the advertisement.

[0059] For example, a method of estimating the advertisement effect of an advertisement based on the total display time of the advertisement displayed on a display device provided in the car and the sales of the store advertised by the advertisement has already been devised. However, in this method, without considering whether the user who boarded the car paid attention to the advertisement displayed on the display device, the advertisement effect of the advertisement is simply estimated based on two elements with low relevance: the total display time of the advertisement and the sales of the store advertised by the advertisement. Therefore, the advertisement effect cannot be accurately estimated.

[0060] On the other hand, as described above, the elevator system according to the present embodiment estimates the advertisement effect of the advertisement based on two highly relevant elements: the occupied floor of the store advertised by the advertisement that the user has paid attention to in the past and the current disembarkation floor of the user. Therefore, compared with the method described above, the advertisement effect can be accurately estimated.

[0061] Also, as another method for estimating the advertising effect, a method has been devised to estimate the advertising effect of an advertisement displayed on a display device having a touch panel function provided in the car based on the operation history of the user with respect to the display device. However, in this method, since an operation on the display device is required of the user (in other words, cooperation is required of the user), there is a problem that it is troublesome from the perspective of the user. Further, in such a method, due to this trouble, positive cooperation of the user cannot be obtained, and there is a possibility that sufficient operation history for estimating the advertising effect cannot be collected.

[0062] On the other hand, the elevator system according to the present embodiment can estimate the advertising effect without requiring any special operation or action of the user boarding the car 11, and is thus useful also in this regard.

[0063] Furthermore, when user information corresponding to the user detected by the user detection unit 23 is not registered in the cloud server 40, the elevator system according to the present embodiment automatically registers the user information corresponding to the user in the cloud server 40. Also, the elevator system according to the present embodiment determines whether or not the user detected by the user detection unit 23 was paying attention to the advertisement displayed on the car interior display device 16, and automatically updates the user information corresponding to the user based on the result of the determination. That is, the elevator system according to the present embodiment can automatically register and update the information necessary for estimating the advertising effect, and can reduce the burden on the operator who operates this system.

[0064] Also, different from the general method for estimating the advertising effect, the elevator system according to the present embodiment can estimate the advertising effect specialized for the environment inside the car 11.

[0065] In the present embodiment described above, it is assumed that the advertisement displayed on the car interior display device 16 is an advertisement related to the stores located in the commercial facility where the car 11 is installed. However, the advertisement displayed on the car interior display device 16 may be an advertisement for promoting an event held on a predetermined floor of the commercial facility or the like.

[0066] Also, in the present embodiment, it is assumed that the advertisement related to the stores located in the commercial facility where the car 11 is installed is displayed on the car interior display device 16. However, an advertisement related to a store located on a floor different from the destination floor of the target user this time may be displayed on the car interior display device 16, and an advertisement related to the store located on the destination floor this time may not be displayed. In this case, when the destination floor is registered by the target user, the elevator control device 30 performs control to distribute an advertisement related to a store located on a floor different from the destination floor to the car interior display device 16.

[0067] Furthermore, in the present embodiment, the user information registration unit 25 determines whether or not the target user has paid attention to the advertisement displayed on the car interior display device 16 based on the image captured by the camera 12 until the target user gets off the car 11 this time. However, the present invention is not limited to this. The elevator system further includes a camera different from 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 paid attention to the advertisement displayed on the car interior display device 16 based on the image captured by the camera.

[0068] According to the above-described embodiment, it is possible to provide an elevator system capable of accurately estimating the advertising effect of the advertisement displayed on the display device provided in the car.

[0069] Although some embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
