Description

[Technical field]

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

[0002] Normally, a passenger who gets into a car presses a destination floor button installed inside the car to register the destination floor. However, for example, if a passenger who is carrying luggage in both hands gets into the car, the passenger needs to place the luggage on the floor in order to press the destination floor button, which makes it difficult to register the destination floor smoothly.

[0003] In recent years, a system that allows users to register destination floors using voice recognition has become known. Using this system, users can register destination floors without putting down their luggage even if their hands are full. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5447659 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned system, if the registration of destination floors by voice recognition is always enabled, the destination floor may be erroneously registered due to conversations between passengers in the car, noise, etc. Therefore, it is desirable to normally disable (OFF) the registration of destination floors by voice recognition, and enable (ON) the registration of destination floors by voice recognition only when a passenger with both hands full with luggage or the like gets on the car.

[0006] Therefore, the problem that the present invention aims to solve is to provide an elevator system that can accurately detect a state in which a user's hands are occupied with luggage or the like, and can register the destination floor of the user. [Means for solving the problem]

[0007] An elevator system according to one embodiment includes a camera, a detection means, a determination means, and a registration control means. The camera is installed inside a car. The detection means detects a user who has entered the car based on an image of the inside of the car captured by the camera. The determination means determines whether or not the user's hands are occupied based on the shape of the user's hands and the positional relationship between the user and an object. When the user's hands are occupied, the registration control means registers a destination floor by voice recognition. [Brief description of the drawings]

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

[0010] Fig. 1 is a diagram showing a schematic configuration example of an elevator system according to an embodiment. Note that, although a single car will be described as an example here, the same configuration applies to a system having multiple cars.

[0011] The camera 12 is installed above the entrance of the car 11. Specifically, the camera 12 is installed in a fascia 11a covering the upper part of the entrance of the car 11, with the lens portion tilted at a predetermined angle directly downward or toward the landing 15 side or the inside of the car 11.

[0012] The camera 12 is a small surveillance camera such as an in-vehicle camera, has a wide-angle lens or a fisheye lens, and captures a predetermined range inside the car 11. The camera 12 is capable of continuously capturing images at several frames per second (e.g., 30 frames / second). The camera 12 is activated when the car 11 arrives at the landing 15 on each floor, and captures an image of a predetermined range L1.

[0013] At the landing 15 on each floor, a landing door 14 is installed at the arrival entrance of the car 11 so as to be able to be opened and closed freely. The landing door 14 engages with the car door 13 when the car 11 arrives and opens and closes. The power source (door motor) is on the car 11 side, and the landing door 14 simply opens and closes following the car door 13. In the following explanation, it is assumed that when the car door 13 is open, the landing door 14 is also open, and when the car door 13 is closed, the landing door 14 is also closed.

[0014] Each image captured by the camera 12 is analyzed in real time by the image processing device 20. Although the image processing device 20 is shown removed from the car 11 for convenience in Fig. 1, in reality, the image processing device 20 is stored in the headboard 11a together with the camera 12.

[0015] The image processing device 20 includes a storage unit 21 and a control unit 22. The storage unit 21 sequentially stores captured images, and has a buffer area for temporarily storing data necessary for processing by the control unit 22. Note that the storage unit 21 may store images that have been subjected to pre-processing such as distortion correction, enlargement / reduction, and partial cropping as pre-processing of the captured images.

[0016] The control unit 22 performs processing for determining whether or not both of the user's hands are occupied, based on the images stored in the storage unit 21. The control unit 22 is composed of a detection unit 23, an object detection unit 24, a hand shape detection unit 25, a positional relationship detection unit 26, and a determination unit 27. Details of the processing method of the control unit 22 will be described later using the flowchart of Fig. 4, so only a brief description will be given here.

[0017] The detection unit 23 detects a user who is in the car 11 based on an image of the inside of the car 11 captured by the camera 12. The object detection unit 24 detects an object in the vicinity of the user detected by the detection unit 23. Note that the "object" includes, for example, luggage, a bag, a cart, etc., and refers to an object that the user can carry by hand. The hand shape detection unit 25 detects the shape of the user's hand detected by the detection unit 23. The "hand shape" includes the shape of the fingers when the user grasps a part of an object, the shape of the fingers when supporting an object, etc. (see Figures 5 and 6). The positional relationship detection unit 26 detects the positional relationship between the user detected by the detection unit 23 and the object detected by the object detection unit 24.

[0018] The determination unit 27 determines whether or not both of the user's hands are occupied, based on the shape of the user's hand detected by the hand shape detection unit 25 and the positional relationship between the user and an object detected by the positional relationship detection unit 26. In detail, the determination unit 27 determines that both of the user's hands are occupied on the image when either of the following conditions (1) and (2) is met.

[0019] (1) The user's hand is in a position to grasp and hold part of an object, and the object is present at the tip of the user's hand. (2) The user's hands are in a position to support and hold an object, and the object is present between the user's hands.

[0020] The elevator control device 30 controls the raising and lowering operation of the car 11 and the operation of various devices (destination floor buttons, lighting, etc.) installed in the car 11. The elevator control device 30 also includes a registration control unit 31, a notification unit 32, and a door opening / closing control unit 33.

[0021] The registration control unit 31 registers the destination floor of the user. Specifically, the registration control unit 31 registers the destination floor of the user by the destination floor button 44 on the operation panel 45. The registration control unit 31 also inputs the user's voice signal from the voice input device 16 installed in the elevator car 11, analyzes and processes the voice signal, and registers the destination floor of the user.

[0022] Hereinafter, registering a destination floor by such a voice signal will be referred to as "registering a destination floor by voice recognition." Registering a destination floor by voice recognition is realized using a known voice recognition technology. For example, the registration control unit 31 compares the voice signal input to the voice input device 16 with a voice signal indicating a floor stored in advance, and if the two match under a predetermined condition, registers the floor corresponding to the voice signal as the destination floor of the user.

[0023] Here, if the registration of the destination floor by voice recognition is always enabled, there is a possibility that the destination floor will be erroneously registered due to the conversation of the user or noise inside the car 11. Therefore, the registration control unit 31 normally disables the voice recognition, and enables the registration of the destination floor by voice recognition when the determination unit 27 determines that the user has both hands occupied.

[0024] When the user has both hands full, the notification unit 32 notifies the user through a speaker 46 installed in the elevator car 11 that the destination floor can be registered by voice recognition.

[0025] The door opening / closing control unit 33 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 33 opens the car door 13 when the car 11 arrives at the landing 15, and closes the door after a predetermined time has elapsed.

[0026] FIG. 2 is a diagram showing an example of the configuration of the area around the entrance / exit inside the car 11. As shown in FIG. A car door 13 is provided at the entrance of the car 11 so as to be able to be opened and closed freely. In the example of Fig. 2, a two-door double-leaf car door 13 is shown, and two door panels 13a, 13b constituting the car door 13 open and close in opposite directions along the width direction (horizontal direction). Note that the "width" is the same as the entrance of the car 11.

[0027] A display 43, an operation panel 45 on which destination floor buttons 44 and the like are arranged, and a speaker 46 are installed on one or both of the front pillars 41a and 41b. In the example of Fig. 2, the speaker 46 is installed on the front pillar 41a, and the display 43 and the operation panel 45 are installed on the front pillar 41b.

[0028] Here, a camera 12 having an ultra-wide-angle lens such as a fisheye lens is installed in the center of a panel 11a above the entrance of the car 11. The camera 12 is installed facing downward from the lower part of the panel 11a.

[0029] Further, a voice input device 16 is installed on the operation panel 45. The voice input device 16 is installed with an input portion facing the inside of the car 11 so that a user can input voice. Note that the voice input device 16 may be installed in a location other than the operation panel 45 as long as it is a position where the voice of a user in the car 11 can be easily input.

[0030] 3 is a diagram for explaining an outline of the operation of the elevator system according to this embodiment. The elevator system according to this embodiment detects a user U who has boarded the car 11 based on an image captured by a camera 12 installed above the entrance of the car 11. Then, it is determined whether or not the user U has both hands occupied. If the user U has both hands occupied, registration of the destination floor by voice recognition is enabled.

[0031] Next, an example of a processing procedure of the elevator system according to this embodiment will be described with reference to the flowchart of FIG. When the car 11 arrives at an arbitrary floor (YES in step S11), the door opening / closing control unit 33 opens the car door 13 (step S12). When the car door 13 opens, the detection unit 23 detects a user who has boarded the car 11 based on an image captured by the camera 12 (step S13).

[0032] As a method of detecting a user, for example, an image captured by the camera 12 is divided into a matrix of predetermined blocks in advance, and a motion detection process is used to detect blocks with movement among these blocks based on a change in brightness. According to the motion detection process, a user captured on the image is detected as a group of moving blocks. The detection unit 23 detects a user who has entered the car 11 by detecting that the group of moving blocks has moved into the car 11.

[0033] The method of detecting users is not limited to the above-mentioned motion detection process, and other image recognition methods may be used. For example, SSD (Single Shot Multibox Detector), which is one of the image recognition methods using supervised learning, may be used. In this case, by learning images of users who have boarded the elevator car 11, it is possible to efficiently detect users who have boarded the elevator car 11, including their boarding positions, from newly acquired images.

[0034] If the detection unit 23 detects a user who has boarded the elevator car 11 (YES in step S13), the object detection unit 24 detects whether or not an object is present near the user detected by the detection unit 23 (step S14).

[0035] Specifically, an image pattern of luggage or the like is stored in advance, and an object that matches the image pattern in the vicinity of the user is detected as an object. Note that an object existing in the vicinity of the user may be detected by the image recognition process of the SSD or the like described above in step S13.

[0036] If there is no object near the user (NO in step S14), it is unlikely that the user has both hands full. For this reason, the registration control unit 31 does not enable destination floor registration by voice recognition, and only registers the destination floor by the user's button operation (step S15).

[0037] If there is an object near the user (YES in step S14), the determination unit 27 determines whether both hands of the user are occupied by an object (baggage, etc.) in the following procedure. First, the determination unit 27 detects the shape of the user's hand using the hand shape detection unit 25 (step S16). In detail, the hand shape detection unit 25 detects that the fingers of the user's hand are in a "shape of grasping part of an object" or a "shape of supporting an object."

[0038] FIG. 5 is a diagram for explaining the "shape for gripping a part of an object." FIG. 5(a) shows the shape of a user's hands 50a, 50b when they grasp the handle of a bag (part of an object). FIG. 5(b) shows the shape of a user's hands 51a, 51b when they grasp the handle of a cart (part of an object) from the upper end direction. In the example of FIG. 5(b), the hands 51a, 51b are shown with the backs of the hands facing up and grasping the handle from above (a forward-handed shape, but the hands 51a, 51b may be reverse-handed, or one may be forward-handed and the other reverse-handed). These shapes are detected as "shapes grasping and holding part of an object."

[0039] FIG. 6 is a diagram for explaining the "shape for supporting an object." Fig. 6(a) shows the shape of the user's hands 52a and 52b when they support the baggage from the side. Fig. 6(b) shows the shape of the user's hands 53a and 53b when they support the baggage from the bottom end. These shapes are detected as "shapes supporting an object." Note that the shapes of gripping and holding a part of an object are not limited to the examples in FIG. 5 and FIG. 6, but include various hand shapes when gripping and holding a part of an object or supporting an object.

[0040] Images (hereinafter referred to as image patterns) of the hand shapes when a user grasps a part of an object such as luggage and the hand shapes when supporting an object, viewed from various angles, are stored in advance in the storage unit 21. The hand shape detection unit 25 detects the shapes of the user's left and right hands touching the object by comparing the image patterns stored in the storage unit 21 with images of the vicinity of both hands of the user.

[0041] Furthermore, the determination unit 27 detects the positional relationship between the user and the object by the positional relationship detection unit 26 (step S17). "Detecting the positional relationship between the user and the object" includes, for example, detecting that an object exists at the fingertips of the user's hand, detecting that an object exists between both hands of the user, and the like.

[0042] The determination unit 27 determines whether or not both of the user's hands are occupied based on the shape of the user's hand detected by the hand shape detection unit 25 and the positional relationship between the user and the object detected by the positional relationship detection unit 26 (step S18). Specifically, it is determined that both of the user's hands are occupied when (1) the user's hand is in a shape that grasps and holds a part of an object and the object is present at the tip of the user's hand, or (2) the user's hand is in a shape that supports and holds an object and the object is present between the user's hands.

[0043] If it is determined that the user's hands are occupied (YES in step S18), the notification unit 32 notifies the user that it is possible to register a destination floor by voice recognition (step S19). The registration control unit 31 enables (ON) the destination floor registration function by voice recognition, making it possible to use both destination floor registration by voice recognition and destination floor registration by the destination floor button 44 (step S20).

[0044] On the other hand, if it is determined that the user's hands are not occupied (NO in step S18), the registration control unit 31 disables (OFF) the destination floor registration function using voice recognition, and allows the user to only register destination floors using button operation (step S15).

[0045] Thereafter, when the elevator car 11 closes its doors and departs for the destination floor (step S21), the process ends here. If destination floor registration by voice recognition is enabled, destination floor registration is disabled (OFF) when all doors of the elevator car 11 are closed in order to prevent erroneous registration due to conversations of users inside the elevator car 11.

[0046] Here, a specific example of determining whether the user has both hands occupied will be described with reference to Figs.

[0047] FIG. 7 is a diagram showing a state in which user U1 is holding the handle of baggage b1 with both hands. In this case, the shape of user U1's hand h1-1 is in a shape in which the handle of baggage b1-1 is being grasped (see FIG. 5(a)). Furthermore, baggage b1-1 is at the tip of user U1's hand h1-1. Furthermore, the shape of user U1's other hand h1-2 is in a shape in which the handle of baggage b1-2 is being grasped (see FIG. 5(a)), and baggage b1-2 is at the tip of user U1's hand h1-2. Therefore, since the shape of the user's hand and the positional relationship between the user and the object meet the above condition (1), it is determined that user U1 has both hands full.

[0048] Fig. 8 is a diagram showing a state in which user U2 is gripping the handle portion of dolly c2 from the upper end direction with both hands. In this case, the shape of user U2's hands h2-1 and h2-2 is such that they are gripping the handle portion of dolly c2 (see Fig. 5(b)). In addition, there are objects (the handle portion of dolly c2 and baggage b2) at the tip of user U2's hands h2-1 and h2-2. Therefore, since the shape of the user's hands and the positional relationship between the user and the object meet the above condition (1), it is determined that user U2 has both hands full.

[0049] Fig. 9 is a diagram showing a state in which user U3 is holding baggage b3 from the side with both hands. In this case, the shapes of user U3's hands h3-1 and h3-2 are in a shape in which the baggage b3 is being held (see Fig. 6(a)). Furthermore, baggage b3 is present between user U3's hands h3-1 and h3-2. Therefore, the shape of the user's hands and the positional relationship between the user and the object meet the above condition (2), and therefore it is determined that user U3 has both hands full.

[0050] Fig. 10 is a diagram showing a state in which user U4 is holding baggage b4 from the lower end direction with both hands. In this case, the shapes of user U4's hands h4-1 and h4-2 are in a shape in which they are holding baggage b4 (see Fig. 6(b)). Furthermore, baggage b4 is present between user U4's hands h4-1 and h4-2. Therefore, since the shape of the user's hands and the positional relationship between the user and the object meet the above condition (2), it is determined that user U4 has both hands full.

[0051] 11 is a diagram showing a state in which both hands of user U5 are free. In this case, the pattern p on user U5's clothes may be erroneously detected as an object, and it may be determined that the object is between hands h5-1 and h5-2. However, the shapes of hands h5-1 and h5-2 do not correspond to either a shape of grasping a part of an object or a shape of supporting an object. Therefore, since the shape of the user's hands and the positional relationship between the user and the object do not correspond to either of conditions (1) and (2), it is determined that user U5 has both hands free.

[0052] FIG. 12 is a diagram showing an example in which one hand h6-2 of user U6 is free because one piece of luggage b6-2 is hanging from the elbow. The shape of user U6's hand h6-1 is in a shape in which the user is grasping the handle of the luggage b6-1 (see FIG. 5(a)). Also, as shown in FIG. 12, the shape of hand h6-2 may be similar to a shape in which an object is grasped. However, neither luggage b6-1 nor luggage b6-2 is at the tip of hand h6-2, nor between hands h6-1 and h6-2. Therefore, the shape of the user's hand and the positional relationship between the user and the object do not meet either of conditions (1) or (2), so it is determined that user U6 does not have both hands full.

[0053] In this way, according to the present embodiment, whether or not both hands of the user are occupied is determined based on the "shape of the user's hand" and the "positional relationship between the user and the object". In this case, in a commonly known method, since the determination is made only based on the "positional relationship between the user and the object", for example, if luggage or the like held by another user in the elevator 11 is present near the hands of the user to be detected, it may be erroneously determined that both hands of the user are occupied. In contrast, by focusing on not only the "positional relationship between the user and the object" but also the "shape of the user's hand" as in the present embodiment, it is possible to make a determination including the way the user holds the object, so that it is possible to accurately detect whether both hands of the user are occupied without being influenced by other users in the elevator 11. As a result, only when a user with both hands occupied gets on the elevator 11, the registration of the destination floor by voice recognition is enabled (ON), and an environment in which the user can register the destination floor hands-free can be provided.

[0054] In addition, when registering a destination floor by voice recognition, if the destination floor spoken by the user is not recognized due to surrounding noise, etc., the user needs to speak the destination floor again, so it takes time to complete the registration of the destination floor. Therefore, when it is determined that the user's hands are occupied, it is preferable to extend the door opening time by the door opening / closing control unit 33 from the normal time. This makes it possible to prevent the door from closing while the user is repeatedly registering the destination floor by voice.

[0055] In addition, in this embodiment, it is determined whether or not the hands of a user who has boarded the elevator 11 are occupied, but it may also be determined whether or not the hands of a user before boarding the elevator 11 (i.e., a user at the platform 15) are occupied.

[0056] (Modification) Since the inside of an elevator car is narrow, a user may overlap with another user and be captured by the camera 12. In this case, if there is another user in front of the user, the other user may be erroneously detected as an object.

[0057] Therefore, in a modification of this embodiment, attention is focused on interruptions in the image of the user to be detected, and a determination is made as to whether or not the object is another user overlapping the target user.

[0058] Fig. 13 is a diagram showing a state in which a user U7 detected on an image is holding a baggage sideways with both hands. b7 indicates a baggage part detected as an object by the object detection unit 24. As shown in Fig. 13, when an image of the central part of the body of the user U7 is interrupted by the baggage part b7, the interrupted part becomes a straight line having a predetermined length L2 (e.g., 3 cm) or more.

[0059] Fig. 14 is a diagram showing a state in which user U8 detected on an image overlaps with another user. b8 is a part of the other user that is erroneously detected as an object by the object detection unit 24. As shown in Fig. 14, when an image of a part of the body of user U8 is interrupted by part b8 of the other user, the interrupted part does not form a straight line.

[0060] In a modified example of this embodiment, it is determined whether an object detected on an image is another user overlapping the user based on the state of interruption of the user's image. Specifically, when an object is detected near a user, the state of interruption of the user's image due to the object is detected. The "state of interruption" refers to a state in which a part of the user's body is interrupted by overlapping with the object, and includes a state in which a pattern on clothing is interrupted.

[0061] The determination unit 27 determines whether or not there is a part of the user's body that is interrupted by a straight line of a certain length L2 or more. If there is a part that is interrupted by a straight line of length L2 or more, the determination unit 27 determines that the interrupted part is an object held by the user, and determines whether or not both of the user's hands are occupied based on the shape of the user's hand and the positional relationship between the user and the object.

[0062] On the other hand, if there is no part of the user's body that is interrupted by a straight line of a certain length L2 or more, the determination unit 27 determines that the interruption is due to the overlap of a part of another user in front of the user. In this case, the determination unit 27 determines that the user's hands are not occupied even if the shape of the user's hands and the positional relationship between the user and the object meet the above conditions (1) and (2).

[0063] The other configurations and processing flows are the same as those of the above-described embodiment except for the addition of a process for determining whether a detected object is a user or not, and therefore will not be described here.

[0064] In this way, by checking where the user is interrupted on the image, when the user overlaps with another user, it is possible to prevent the other user from being mistakenly detected as an object such as luggage, and to correctly determine whether the user's hands are occupied.

[0065] According to at least one of the embodiments described above, it is possible to provide an elevator system that can accurately detect a state in which a user's hands are occupied with luggage or the like and register the destination floor of the user.

[0066] Although some 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 embodiments can be implemented 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 in the scope of the invention and its equivalents described in the claims, as well as in the scope and spirit of the invention.
