Description

  Embodiments described herein relate generally to an elevator call registration device that uses line-of-sight input.

  As an elevator call registration device, there is one in which a passenger performs call registration by operating a hall call button or a destination floor registration button provided in a hall or a car.

  Several proposals have been made so that call registration is possible even for passengers who are difficult to operate buttons, such as passengers with disabilities.

  For example, a space for clearly indicating the position where the passenger stands is provided, the passenger's line of sight captured by a camera that captures the line of sight of the passenger in the space is processed, and a hall call button or destination provided in the hall or car There is one that enables call registration without operating a floor / floor display button (see, for example, Patent Document 1).

  In addition, when it is determined from an image taken by a camera provided in the car that the passenger's line of sight registered in advance is directed to a predetermined location, the nearest floor stop door is opened or an alarm is issued. There is one that performs processing for reporting to the outside of the bulletin board or the car (for example, see Patent Document 2).

  However, when operating in front of an operation panel for call registration provided in the car, it is not easy for a wheelchair user passenger to press the hall call button. In addition, when other passengers are standing in front of the operation panel, it becomes an obstacle for camera shooting, and wheelchair users are difficult to recognize from the camera and the destination floor registration button is hidden, so call registration Difficult to do.

  The problem to be solved by the present invention is to provide an elevator call registration device that can easily perform call registration such as registration of a destination floor even for a wheelchair user who is difficult to operate an operation panel in a car. .

  The elevator call registration device according to the embodiment is installed on the back side of the elevator cab and displays a security camera for photographing the cab interior and the opening / closing of the destination floor of the cab and the entrance door of the cab A display unit for call registration, a line-of-sight recognition camera that captures the line-of-sight direction of an elevator passenger directed to the display unit, a video signal received from the security camera and the line-of-sight recognition camera, and display on the display unit A control unit to control, when the passenger is determined to be a wheelchair user via the security camera, the control unit calculates a gaze position coordinate based on a gaze direction directed to the display unit, Call registration is enabled after the line-of-sight position on the display is determined.

It is a general-view figure of the elevator cab which concerns on this embodiment. It is explanatory drawing which shows the detail of a display part. It is a flowchart which shows the flow of the call registration process by a gaze input.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same portions are denoted by the same reference numerals, and redundant description is omitted.

  The elevator call registration device according to the present embodiment is arranged in a passenger compartment, accepts a line-of-sight input for a specific passenger such as a wheelchair user, calls for registration of a destination floor, extension of opening and closing of an entrance door, etc. Register.

  FIG. 1 is a schematic view of an elevator cab according to the present embodiment. As shown in FIG. 1, a curtain plate portion 1 is provided above the entrance of the cab 10. The curtain plate portion 1 constitutes an upper front portion of the three-way frame of the passenger compartment. An in-car operation panel 3 is provided in the vicinity of the entrance door 2, for example, on the right side. A security camera 4 is disposed in the back of the passenger compartment 10, that is, on the back side. The video signal of the security camera 4 is connected to be transmitted to the control unit 5. The control unit 5 can be installed on the passenger compartment 10, for example. Note that the control unit 5 can be incorporated in the in-car operation panel 3.

  The in-car operation panel 3 is provided with an elevator destination floor registration button and an operation button for opening and closing the entrance door. It is also preferable that the in-car operation panel 3 has a built-in communication device (not shown) for contacting the outside in an emergency.

  The security camera 4 monitors the elevator cab 10 used by unspecified persons. The video from the security camera 4 is transmitted to the control unit 5 and also sent to, for example, a monitoring center (not shown). In the present embodiment, the security camera 4 is used to determine that the passenger of the elevator is a wheelchair user.

  The control unit 5 receives the video signal captured by the security camera 4 and determines whether or not the elevator passenger is a wheelchair user by image processing. The discrimination is performed by extracting a characteristic form of the wheelchair using a well-known image processing technique. Here, details of the image processing are not mentioned.

  In the elevator cab 10 according to the present embodiment, a line-of-sight recognition camera 6 and a display unit 7 are disposed on the curtain plate unit 1. FIG. 2 is an explanatory diagram showing details of the display unit 7.

  The line-of-sight recognition camera 6 captures the line of sight of the user (input person) as an image in order to detect the position of the line of sight of the user. The line-of-sight recognition camera 6 grasps the line-of-sight position based on, for example, the movement of the user's eyeball, and captures an image of a particular eye portion of the face. The output signal of the line-of-sight recognition camera 6 is sent to the control unit 5 through the signal line. The security camera 4 described above can be installed so as to be synchronized with the line-of-sight recognition camera 6.

  The control unit 5 performs processing for detecting eye movement, which part of the display unit 7 the user is viewing, that is, the line-of-sight direction, based on an image captured by the line-of-sight recognition camera 6.

  When the line-of-sight direction is in the line-of-sight input area of the display unit 7, the intersection of the line-of-sight direction (straight line) and the line-of-sight input region (plane), that is, the coordinates of the line-of-sight position on the display unit 7 is calculated by the control unit 5. . For example, in the display unit 7 indicating the floors from the first floor to the fifth floor, it is determined whether the line of sight is aligned with “3” indicating the third floor or “4” indicating the fourth floor. To do.

  The display unit 7 functions as a display for displaying information, and can be configured by, for example, a liquid crystal display. The display unit 7 includes, for example, a destination floor display 71 and a door opening / closing display 72. Therefore, the line-of-sight position is position information indicating a specific position in the destination floor display 71 and the door opening / closing display 72 when performing line-of-sight input. This line-of-sight position information is sent from the control unit 5 to the display unit 7 as a display control signal.

  The above-described line-of-sight input areas are a destination floor display 71 and a door opening / closing display 72, and for example, it is possible not to react to the frame portion of the display unit 7.

  The display unit 7 that has received the display control signal from the control unit 5 blinks a specific part of the destination floor display 71 or the door opening / closing display 72 where the wheelchair user turns his / her line of sight.

  Since elevator passengers are not only wheelchair users, line-of-sight input cannot always be performed smoothly. Therefore, it may not be appropriate to immediately turn on the specific location and register the call. Therefore, in call registration by blinking line-of-sight input, the process of determining the line-of-sight input (decision input) should be performed.

  As this decision input processing, for example, after introducing the line-of-sight position to a specific position on the destination floor display 71 and the door opening / closing display 72, a decision input is performed by repeating the operation of “blink” a predetermined number of times. Can do. Alternatively, a determination input can be made when the line-of-sight position is maintained at the specific position for 2 seconds.

  The decision is made to turn on a specific part of the destination floor display 71 or the door opening / closing display 72 where the wheelchair user turns his line of sight, and register the call.

  In addition, it is possible to provide a countermeasure for canceling the gaze input content once determined. For example, if a display part for cancellation (not shown) is provided on one end side of the display unit 7 and there is a gaze input over a specific time in the part, the gaze input determined immediately before is invalidated. Can do.

(Modification 1)
In high-rise buildings, there are many floors where elevators stop, and it is not appropriate to make the destination floor display long for line-of-sight input.

  Therefore, it is also preferable to scroll the displayed destination floor display in the upward or downward direction to promptly display the desired destination floor and accept the line-of-sight input. Therefore, for example, “↑” for raising the destination floor display or “↓” for lowering can be arranged on the display unit 7.

(Modification 2)
A line-of-sight recognition camera 6 and a display unit 7 can also be disposed on the back side of the passenger compartment 10. When it is also provided on the back side, it is not necessary to turn the wheelchair user in the car once he / she gets in or to get into the car room 10 in a rearward state.

(Function / Function)
The operation of the call registration device configured as described above will be described. FIG. 3 is a flowchart showing a flow of call registration processing by line-of-sight input.

  First, the security camera 4 attached to the back side of the passenger compartment 10 recognizes a passenger (step S31). The image information of the security camera 4 is sent to the control unit 5 to determine whether the passenger is a wheelchair user (step S32).

  If the user is a wheelchair user, call registration by line-of-sight input is accepted (step S33), and the line-of-sight recognition camera 6 is activated (step S34). By allowing only wheelchair users to perform call registration by line of sight, mischief of persons who are not wheelchair users can be eliminated.

  Next, the image information captured by the line-of-sight recognition camera 6 is transmitted to the control unit 5 via a signal line. The control unit 5 calculates the line-of-sight position coordinates based on the line-of-sight direction that has entered the line-of-sight input area (step S35), and the wheelchair user directs the line of sight to a specific floor of the destination floor display 71, for example, the destination floor display 71. Or whether the line of sight is directed to the door opening / closing display 72.

  Based on the line-of-sight position coordinates, the control unit 5 blinks the corresponding line-of-sight input area of the display unit 7, that is, the specific floor of the destination floor display 71 or the door open / close display 72 (step S36).

  Next, the control part 5 discriminate | determines whether there exists a change of the gaze direction by a wheelchair user (step S37).

  When there is a change in the line-of-sight direction (Yes in step S37), for example, when the wheelchair user shifts his line of sight from the destination floor to which the initial line of sight is directed, the process proceeds to step S35. Then, the blinking part moves to the specific floor of the destination floor display 71 or the door opening / closing display 72 to which the line of sight is newly directed.

  If there is no change in the line-of-sight direction (No in step S37), the line-of-sight position is determined (step S38). The determination of the line-of-sight position can be triggered by, for example, a wheelchair user blinking (for example, meditating for 1 second or more) in a state where a specific part of the display unit 7 is blinking.

  Next, the control unit 5 registers a call (step S39), and turns on the corresponding line-of-sight input area of the display unit 7 (step S40). Note that the call may be registered after the order of steps S39 and S40 is switched to light the line-of-sight input area.

  As described above, according to the present embodiment, call registration such as registration of a destination floor can be easily performed even for a user who is difficult to operate an elevator car operation panel such as a wheelchair user.
