[0013] Hereinafter, an embodiment will be described with reference to the drawings. Note that elements common to the various drawings are given the same reference numerals and redundant explanations will be omitted.

[0014] 1. Embodiment 1. 1-1. Overview of the elevator display system according to embodiment 1 FIG. 1 is a diagram showing an example of the configuration of an elevator display system according to embodiment 1. The display system 100 is a system that generates an illustrated image showing an overhead view of the elevator usage status and displays the generated illustrated image in the air. The illustrated image here includes a figure, or a combination of a figure with a color or text, etc. The illustrated image may be a still image, or may include moving image material or a moving image with an animation effect in part or in whole.

[0015] An elevator to which the display system 100 is applied is installed in a facility consisting of a building or the like having multiple floors. An elevator shaft is provided in the facility. The shaft is a long space extending vertically across multiple floors. An elevator hall 4 is provided on each floor of the facility. The hall 4 is located adjacent to the shaft. A hall door 6 is provided at the entrance / exit of the hall 4 on each floor. The hall door 6 is a door that separates the hall 4 from the shaft. The hall door 6 is, for example, a center-opening door in which two panels open and close in the left-right direction, with the center of the hall entrance / exit in the left-right direction as the door closing position. The hall door 6 may also be a single-wing door in which two panels open and close in the left-right direction, with the door closing position at the right or left end of the hall entrance as the starting point.

[0016] The elevator includes a car 2 and a door opening / closing control device 22. The car 2 travels up and down the elevator shaft to transport passengers and other passengers between multiple floors. The car 2 is equipped with a pair of car doors 3 at the car entrance that can be opened and closed left and right. The car doors 3 are either a center-opening type or a single-opening type, the same type as the hall doors 6.

[0017] When the car 2 stops at any floor, the car door 3 is opened and closed in conjunction with the hall door 6 of the hall 4 of that floor by the door opening / closing control device 22 so that passengers can get on and off at the hall 4 of that floor and at the car 2. In other words, the door opening / closing control device 22 functions as a device that opens and closes the elevator doors, including the car door 3 and the hall door 6. There are no limitations on the configuration of the door opening / closing control device 22. The door opening / closing control device 22 may be configured to mechanically engage and link the hall door 6 with the car door 3, or may be configured to electrically link and open and close the respective doors. In the following description, the time from when the door opening / closing control device 22 opens the elevator door to when it closes it will be referred to as the "door opening time."

[0018] The display system 100 includes an aerial display device 10, an imaging device 20, a management server 30, and the above-described door opening / closing control device 22. The management server 30 is connected to the aerial display device 10, the imaging device 20, and the door opening / closing control device 22 via a communication network 8 such as the Internet.

[0019] The aerial display device 10 has a function of displaying in the air an illustration image output from a management server 30, which will be described later. The aerial display device 10 is installed, for example, on the wall surface of the boarding hall 4, and displays the illustration image in the air toward the boarding hall 4.

[0020] FIG. 2 is a diagram showing an example of an aerial display device. In the example shown in FIG. 2, the aerial display device 10 includes a display 12, a beam splitter 14, and a retroreflector 16. The display 12 displays an image. Light emitted from the display 12 is incident on the beam splitter 14. The beam splitter 14 reflects the light from the display 12. The light from the display 12 reflected by the beam splitter 14 is incident on the retroreflector 16. The retroreflector 16 has the function of reflecting light incident from a light source back toward the light source. Therefore, the light from the display 12 reflected by the beam splitter 14 is reflected by the retroreflector 16 back toward the beam splitter 14. The light from the display 12 reflected by the retroreflector 16 is transmitted through the beam splitter 14. Light from the retroreflector 16 that passes through the beam splitter 14 forms an image at the relative position of the beam splitter 14 and the display 12. In this way, by displaying the generated image on the display 12, an illustrated image is displayed in the air at a position away from the wall of the hall 4 where the aerial display device 10 is installed. In the following description, the illustrated image displayed in the air by the aerial display device 10 is also referred to as an "aerial image."

[0021] There is no limitation on the imaging method of the aerial display device 10. That is, the aerial display device 10 may be configured to display an aerial image by employing an imaging method using an orthogonal mirror array or a hexahedral prism element.

[0022] The imaging device 20 is a camera installed to capture images inside the car 2. The imaging device 20 periodically captures and outputs images of passengers riding in the car 2. There are no limitations on the type, number, or installation location of the imaging devices 20 inside the car 2. The image data captured by the imaging device 20 will be referred to as "image data" hereinafter. The image data is not limited to still image data, but may also be video data. The image data is transmitted to the management server 30 via a communication network 8 such as the Internet.

[0023] The management server 30 functions as an information processing device that processes information. Typically, the management server 30 receives image data periodically captured by the imaging device 20. This process is hereinafter referred to as the "acquisition process." The management server 30 analyzes the attributes of users within the analysis target area based on the acquired image data. This process is hereinafter referred to as the "analysis process." The information analyzed by the analysis process is hereinafter referred to as "user information." The user information here includes, as information for distinguishing user attributes, attributes such as adult, child, stroller, cart, wheelchair, and robot, as well as the degree of congestion within the analysis target area. The degree of congestion is expressed as a graded index, such as "low," "medium," and "high." In the analysis process, the degree of congestion is analyzed based on the attributes of users within the analysis target area, the number of users, and the size of the analysis target area. Note that the analysis target area here is, for example, the area within the car 2. In the analysis process, for example, known image analysis processing techniques are used.

[0024] Furthermore, the management server 30 generates an illustrated image to be displayed in the air by the aerial display device 10 based on the user information analyzed by the analysis process. This process will be referred to as the "image generation process" hereinafter. An example of the illustrated image is an image illustrating the status of users in the car 2, such as the attributes of the users in the car 2 and the congestion level in the car 2, as an overhead view. The generated illustrated image is displayed in the air by the aerial display device 10. This process will be referred to as the "display process" hereinafter.

[0025] Furthermore, the management server 30 determines whether a door-open extension operation is necessary to extend the door-open time. This process is hereinafter referred to as the "determination process." In the determination process, for example, if a user who requires time consideration for boarding and disembarking and who has an attribute such as a stroller, a cart, or a wheelchair is riding in the car 2, it is determined that a door-open extension operation is necessary. If a door-open extension operation is necessary, the management server 30 controls the door opening / closing control device 22 to execute the door-open extension operation.

[0026] According to the display system 100 described above, an illustrated image showing the status of users inside the car 2 as an elevator usage status is generated and displayed in the air at the hall 4 before the car 2 arrives at the hall 4. This makes it possible to inform users waiting at the hall 4 of the status inside the car 2 in advance by using an easily recognizable overhead view.

[0027] 2. Configuration of the Display System Fig. 3 is a block diagram showing an example of the configuration of the display system according to embodiment 1. The display system 100 includes the above-described aerial display device 10, an imaging device 20, a door opening / closing control device 22, and a management server 30.

[0028] The management server 30 has the functions of an information processing device as a computer. The management server 30 is installed within the facility to be controlled. Alternatively, the management server 30 may be installed in a remote location different from the facility to be controlled. As another example, the management server 30 may be realized by a server on the cloud. When the management server 30 is installed in a remote location, the management server 30 transmits and receives data between the aerial display device 10, the imaging device 20, and the door opening / closing control device 22 via a communication network 8 such as the Internet.

[0029] The management server 30 includes at least one processor 40 and at least one memory 50. The memory 50 serves as a storage device and stores at least one program 52 executable by the processor 40, an illustration DB 54, and various related data 56. The program 52 may be recorded on a computer-readable recording medium. The illustration DB 54 stores data on illustrations used when generating illustrated images, such as illustrations corresponding to user attributes and illustrations corresponding to the degree of congestion.

[0030] The processor 40 executes the program 52 to realize various processes. Fig. 4 is a block diagram showing functions realized by the processor of the management server executing the program. As shown in Fig. 4, the processor 40 includes an acquisition unit 41, an analysis unit 42, an image generation unit 43, a display unit 44, a determination unit 45, and a command unit 46. The functions of the processor 40 will be described below with reference to Fig. 1 as well.

[0031] The acquisition unit 41 is a functional block for performing acquisition processing. In the acquisition processing, the acquisition unit 41 acquires imaging data from the imaging device 20.

[0032] The analysis unit 42 is a functional block for performing analysis processing. In the analysis processing, the analysis unit 42 calculates the attributes of the users in the car 2 and the degree of congestion in the car 2 by performing known image analysis processing on the acquired image data. For example, the degree of congestion is analyzed based on the attributes of the users in the car 2, the number of users, and the size of the car 2. As an example, the degree of congestion is set in stages according to the ratio of the number of users to the capacity of the car 2. In this case, the number of users is counted according to the attributes of the users. For example, users with attributes such as wheelchairs, strollers, or carts that require more space than one adult are counted as two users. The estimated attributes and degree of congestion of the users are temporarily stored as user information in the data 56 area of ​​the memory 50.

[0033] The image generation unit 43 is a functional block for performing an image generation process for generating an illustration image. In the image generation process, the image generation unit 43 generates an illustration image based on the user information analyzed by the analysis process. Specifically, the image generation process uses the illustration DB 54.

[0034] FIG. 5 is a functional block diagram showing the internal functions of the image generation unit 43. The image generation unit 43 includes a data acquisition unit 432 and an extraction unit 434. The data acquisition unit 432 is a functional block for acquiring user information necessary to generate an illustration image. The extraction unit 434 is a functional block for extracting an illustration image corresponding to the user information from an illustration DB 54 stored in the memory 50. The illustration DB 54 stores, for each user attribute and congestion level, illustration images in which one or more user illustrations corresponding to the user attributes are arranged according to the congestion level in a car interior image obtained by perspectively viewing the inside of the car from above. The extraction unit 434 extracts an illustration image corresponding to the user attributes and congestion level included in the user information.

[0035] FIG. 6 is a diagram illustrating illustrative images corresponding to the attributes of users. (A) to (D) in the diagram illustrate bird's-eye views of the situation of users in the car, for each attribute of the user. (A) in the diagram is an illustration in which the user is a person, illustrating an example of an adult and a child riding in the car. (B) in the diagram is an illustration in which the user is using a wheelchair or a stroller. (C) in the diagram is an illustration in which the user is using a cart. Finally, (D) in the diagram is an illustration in which the user is a self-propelled robot.

[0036] FIG. 7 is a diagram illustrating an example of an illustration image that further reflects the degree of congestion in addition to the user attributes. The extraction unit 434 generates an illustration image by combining one or more illustrations extracted from the illustration DB 54 depending on the degree of congestion. (A) to (C) in FIG. 7 illustrate an example of an illustration showing a bird's-eye view of the state inside the car when the degree of congestion is low, medium, and high, respectively, when the user inside the car is a person. Note that (A) to (C) in FIG. 7 illustrate an example of an illustration image in which a color corresponding to the degree of congestion is added to the inside of the car.

[0037] The display unit 44 is a functional block for performing display processing. In the display processing, the display unit 44 displays an aerial image of the illustrated image generated by the image generation unit 43 on the aerial display device 10 before the car 2 arrives at the platform 4.

[0038] The determination unit 45 is a functional block for performing a determination process to determine whether or not a door-open extension operation is required based on user information. The command unit 46 is a functional block for causing the door opening / closing control device 22 to execute a door-open extension operation. This process will be referred to as "command processing" hereinafter.

[0039] 1-3. Specific Processing Executed in the Display System Figure 8 is a flowchart of a routine executed in the display system of embodiment 1. This routine is repeatedly executed at a predetermined control period by processor 40 of management server 30. This routine also represents part of a display method for aerial display of elevator user status in display system 100.

[0040] In step S100, an acquisition process is performed to acquire image data captured by the image capture device 20. The acquired image data is temporarily stored in the data 56 area of ​​the memory 50.

[0041] In step S102, user information is acquired by an analysis process. Typically, the image data acquired by the acquisition process is subjected to a known image analysis process to analyze the attributes of the users in the car 2 and the degree of congestion in the car 2. The analyzed attributes and the degree of congestion are temporarily stored in the data 56 area of ​​the memory 50 as user information.

[0042] In step S104, it is determined whether one or more users are in car 2. Here, the presence or absence of users in car 2 is determined based on the user information acquired by the analysis process. Alternatively, if a weighing device that measures the load on car 2 is provided, the presence or absence of users in car 2 may be determined based on the measurement value of the weighing device. Alternatively, if a sensor such as an infrared sensor that detects the presence or absence of an object in car 2 is provided, the presence or absence of users in car 2 may be determined based on a signal from the sensor. As a result, if the determination is successful, the process proceeds to step S106. On the other hand, if the determination is not successful, it is determined that there is no need to display the situation inside car 2, and the process returns to step S100.

[0043] In step S106, it is determined whether the attributes of the users in car 2 have been analyzed. If the determination is negative, it is determined that there is no need to display the status inside car 2, and the process returns to step S100. On the other hand, if the determination is positive, the process proceeds to step S108.

[0044] In step S108, an illustration image is generated based on the user information. Here, an image generation process is executed to generate an illustration image that reflects the attributes of the users in car 2 and the degree of congestion in car 2 in an overhead view, based on the status of the users in car 2.

[0045] When the process of step S108 is completed, the process proceeds to step S110. In step S110, prior to the timing when the car 2 arrives at the hall 4, the illustrated image generated by the image generation process is displayed in the air by the aerial display device 10 installed at the hall 4.

[0046] When the processing of step S110 is completed, the processing proceeds to step S112. In step S112, it is determined whether a door-open extension operation is required. Here, a determination process is executed to determine whether the user attributes contained in the user information include attributes that require consideration of the door-open time. As a result, if the determination is not established, the door-open extension operation is not executed and this routine is terminated. On the other hand, if the determination is established, it is determined that a door-open extension operation is required, and the processing proceeds to step S114.

[0047] In step S114, command processing is executed and an operation command for the door open extension operation is sent to the door opening / closing control device 22. The door opening / closing control device 22 executes the door open extension operation in accordance with the received operation command.

[0048] According to the display system 100 described above, an illustrated image showing the status of users inside the car 2 from a bird's-eye view is displayed in the air at the landing 4 before the car 2 arrives at the landing 4. This makes it possible to inform users waiting to board at the landing 4 of the status inside the car 2 before the car 2 arrives in an easy-to-understand manner using an aerial image with excellent design and visibility. Furthermore, because the aerial image is displayed in the space of the landing 4, it is possible to inform users who are in a position where they cannot see the wall of the landing 4 of the status inside the car 2. Furthermore, because the aerial image of the illustrated image is an image showing a bird's-eye view of the users inside the car 2, it is easy to intuitively recognize the status of the users inside the car 2.

[0049] In addition, the illustrated image visually represents the attributes of the users in car 2, so users who see the aerial image have enough time to decide in advance whether or not consideration is needed for the users in car 2 and act accordingly. Furthermore, the illustrated image visually represents the degree of congestion in car 2, so users who see the aerial image can decide in advance whether or not they can board the train depending on the degree of congestion in car 2.

[0050] 1-4. Modifications The display system 100 of the first embodiment may employ the following modifications.

[0051] 1-4-1. Hardware resources of information processing devices

[0052] FIG. 9 is a diagram showing a modified example of the hardware resources of a management server serving as an information processing device. In the example shown in FIG. 9, the management server 30 serving as an information processing device includes, for example, a processor 40, a memory 50, and a processing circuit 72 including dedicated hardware 70. FIG. 9 shows an example in which some of the functions of the management server 30 are realized by the dedicated hardware 70. All of the functions of the management server 30 may also be realized by the dedicated hardware 70. The dedicated hardware 70 may be a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. Note that this modified example may also be applied to the display system of embodiment 2 described below.

[0053] 1-4-2. Functional Arrangement of Management Server 30 Some of the functions of the management server 30 may be installed in other devices such as the imaging device 20, the aerial display device 10, and the door opening / closing control device 22. This modified example may also be applied to the display system of the second embodiment described later.

[0054] 1-4-3. Aerial Display Device There are no limitations on the placement of the aerial display device 10 at the landing 4. Figure 10 is a diagram showing a modified example of the placement of the aerial display device at the landing. In the modified example shown in this figure, the aerial display device 10 is installed on the wall surface above the landing door 6. With this placement of the aerial display device 10, the aerial image is displayed at a position higher than the landing door 6, thereby increasing visibility for users around the landing door 6.

[0055] 1-4-4. Door Opening Extension Operation The functional configuration and the processing executed related to the door opening extension operation are not essential.

[0056] 1-4-5. Image Generation Processing In the image generation processing, the process by which the image generation unit 43 generates an illustrative image is not limited to the method described above. That is, in the image generation processing of a modified example, the extraction unit 434 of the image generation unit 43 extracts, from the illustration DB 54, an image of the interior of the car seen from above through a perspective of the interior of the car and a user illustration corresponding to the attributes of the user. Then, the extraction unit 434 generates an illustrative image by combining one or more user illustrations with the image of the interior of the car according to the degree of congestion. This processing also makes it possible to generate an illustrative image that reflects the attributes of the users in the car 2 and the degree of congestion in the car 2.

[0057] In addition, in the image generation process, it is not necessary to add a color according to the degree of congestion. For example, in the image generation process, instead of color, a highlighting display such as a texture may be added to the illustration image. Furthermore, the color of the illustration image may be changed according to the number of car call registrations at each hall 4 and the number of times the destination floor registration button is pressed in the car 2.

[0058] 2. Second Embodiment In the second embodiment, differences from the example disclosed in the display system 100 of the first embodiment will be described in particular detail. For features not described in the second embodiment, any of the features of the example of the display system 100 disclosed in the first embodiment may be adopted.

[0059] 2-1. Features of the elevator display system in embodiment 2 Fig. 11 is a diagram showing an example of the configuration of the elevator display system in embodiment 2. The display system 100 in embodiment 2 has the same configuration as the display system in embodiment 1, except for the installation locations of the aerial display device 10 and the imaging device 20.

[0060] The imaging device 20 is a camera installed in the elevator hall 4. The imaging device 20 periodically captures and outputs images of users waiting to board the elevator in the hall 4. There are no limitations on the type, number, or installation location of the imaging device 20 in the hall 4.

[0061] The aerial display device 10 is installed on a wall surface inside the car 2, and displays an illustrated image in the air toward the platform 4. In the example shown in FIG. 11 , the aerial display device 10 is installed on the side of the front where the car door 3 is installed inside the car 2. There are no restrictions on the installation location of the aerial display device 10, as long as it can display an aerial image in a position visible to passengers riding in the car 2. FIG. 12 is a diagram showing a modified example of the arrangement of the aerial display device inside the car. In the modified example shown in this figure, the aerial display device 10 is installed above the side wall surface inside the car 2. With this arrangement of the aerial display device 10, the aerial image is displayed at a high position inside the car 2, thereby increasing visibility for passengers inside the car 2.

[0062] In the analysis process, the management server 30 analyzes the attributes of users around the hall door 6 of the hall 4, which is the analysis target range, and the congestion level of the hall 4, based on the imaging data acquired from the imaging device 20. Furthermore, in the image generation process, the management server 30 generates an illustrated image to be displayed in the air by the aerial display device 10, based on the user information analyzed by the analysis process. The illustrated image here is, for example, an image illustrating information on the attributes and congestion level of users around the hall door 6 of the hall 4 as a bird's-eye view, as the situation of users waiting to board at the hall 4.

[0063] FIG. 13 is a diagram illustrating illustrative images corresponding to the attributes of users. (A) to (D) in the figure show bird's-eye views of the situation of users at platform 4, sorted by user attribute. (A) in the figure is an illustration of a case where the user is a person, illustrating an example of an adult and a child waiting to board. (B) in the figure is an illustration of a case where a user using a wheelchair or a stroller is waiting to board. (C) in the figure is an illustration of a case where a user using a cart is waiting to board. Finally, (D) in the figure is an illustration of a case where a user who is a self-propelled robot is waiting to board.

[0064] 14 is a diagram illustrating an example of an illustration image that further reflects the degree of congestion in addition to the attributes of users. The extraction unit 434 generates an illustration image by combining one or more illustrations extracted from the illustration DB 54 depending on the degree of congestion. (A) to (C) in FIG. 14 illustrate an example of an illustration showing a bird's-eye view of the state inside the car when the degree of congestion is low, medium, and high, respectively, when the number of users at hall 4 is one.

[0065] According to the display system 100 described above, an illustrated image showing the status of users at hall 4 from a bird's-eye view is displayed in the air inside car 2 before car 2 arrives at hall 4. This allows users inside car 2 to be visually informed of the status of hall 4 in advance in an easy-to-understand manner. Furthermore, because the aerial image is displayed in the space inside car 2, it is possible to inform users who are in a position where they cannot see the wall inside car 2 of the status of hall 4. Furthermore, because the illustrated image displayed in the air is an image showing a bird's-eye view of users waiting to board at hall 4, it is easy for users to intuitively recognize the status of users at hall 4.

[0066] In addition, the illustrated image visually represents the attributes of users at platform 4, so users who see the aerial display can determine in advance whether or not consideration should be given to users waiting to board at platform 4.
