It includes a unit 14, an attribute table 15, a display content determination unit 16, and a display image table 17.

  The first image processing unit 11 performs image processing on the imaging data input from the imaging device 4 and identifies the presence/absence of a user who is approaching the entrance of the escalator 2. For example, the face image of the user is detected from the captured data to identify whether or not the person is a person. The number-of-people determination unit 12 determines the number of users who are approaching the entrance based on the identification result by the first image processing unit 11. When face images are detected, the number of users is determined from the number of face images.

  The second image processing unit 13 performs image processing on the imaging data input from the imaging device 4, refers to the attribute table, and extracts the attribute of the user who is approaching the entrance of the escalator 2. In this embodiment, the age group (adult or child) is extracted as the attribute of the user. The age group can be accurately extracted from the face image of the user identified by the first image processing unit 11. In the attribute label, the facial features of a child, the facial features of an adult, and the like are stored, and it is determined whether the user is a child or an adult based on the features of the facial image of the user. When the number of users determination unit 12 determines that there are multiple users, the attributes of each of the multiple users are extracted.

  The display content determination unit 16 refers to the display image table 17 based on the number of users determined by the number determination unit 12 and the attributes of the users extracted by the second image processing unit 13. The display content to be projected and displayed as the alerting information, that is, the pattern (image) of the alerting information is determined.

  The projection control unit 18 controls the drive of the projection device 5 to project and display the pattern of the attention information determined by the display content determination unit 16.

  From the image capturing device 4, the first image processing unit 11, the number-of-people determination unit 12, the second image processing unit 13, the attribute determination unit 14, and the attribute table 15 of the control device 10, a user who attempts to pass through the passage area. An information acquisition unit that acquires information about the user is configured. Further, the display content determination unit 16 and the display image table 17 of the control device 10 constitute a notification information determination unit that determines the notification information to notify the user based on the information obtained by the information acquisition unit. The projection control unit 18 and the projection device 5 of the control device 10 display the image of the notification information determined by the notification information determination unit on the upstream side in the traveling direction of the user with respect to the passage area and in the traveling direction of the user. A projection display unit configured to project and display the image is configured.

  FIG. 5 is a diagram showing display patterns stored in the display image table 17 of the control device 10 provided in the notification information display device 1 according to the number of users and attributes.

Image C is a caution image that is held by the handrail and urges you to ride inside the yellow line.

(Operation of Notification Information Display Device 1)
FIG. 6 is a flowchart showing the operation of the notification information display device 1. The imaging device 4 always photographs the area upstream of the entrance of the escalator 2 in the traveling direction of the escalator 2 (S1). The captured imaging data is output from the imaging device 4 to the control device 10. The control device 10 determines whether or not there is a user (human) who is approaching the entrance of the escalator 2 based on the imaging data received from the imaging device 4 (S2). The control device 10 determines the presence/absence of a person (user), for example, by extracting a face image from the imaged data, and determines that the user is present when the face image is detected. When determining that there are users, the control device 10 advances the processing to S3 and determines the number of people. After that, the control device appropriately performs the processes of S4, S5, and S6, and "user is one child", "user is one adult", "user is multiple and all children", "user" Is "all adults" or "users are multiple adults and children". The control device 10 determines an image to be projected and displayed based on a result (attribute and number of users) determined by appropriately performing the processes of S4 to S6.

  The control device 10 drives the projection device 5 so as to display the determined projection image. When it is determined that "the user is the only child" (YES in S4), the projection device 5 projects the image A shown in FIG. 5 on the floor surface in front of the feet of the user (S7). . Similarly, when it is determined that "the user is plural and all are children" (YES in S5), the image A is projected (S9). When it is determined that the user is an adult alone (NO in S4), the image C shown in FIG. 5 is projected (S8). Similarly, when it is determined that "the user is plural and all are adults" (YES in S6), the image C is projected (S10). When it is determined that "a plurality of users are a mixture of adults and children" (NO in S6), the image B shown in FIG. 5 is projected (S11).

  In S12, the control device 10 determines the display end of the image projected and displayed in any of S7 to S11. For example, when a preset time has elapsed after the projection display, it is determined that the display has ended. When it is determined in S12 that the display has ended, the control device 10 drives the projection device 5 to end the projection display (S13), and returns the process to S1.

(Effect of notification information display device 1)
As described above, the notification information display device 1 determines the number and attributes of the users who use the escalator 2, selects the caution information suitable for the user, and displays the image of the selected caution information to the user. Projected and displayed on the floor in front of your feet.

  The attention information displayed in the image is limited to the attention information suitable for the user based on the number and attributes of the users, so that the user can effectively grasp the necessary attention information. be able to. Also, if displayed together with the reminder information that is not very relevant to the user or a lot of information that is relevant to the user but cannot be grasped at a glance, the user's interest may be diminished and may not be visually recognized. However, by narrowing down the appropriate alerting information in this way, it is possible to attract the user's attention and effectively grasp the alerting information.

  Moreover, the image of the alert information is displayed on the floor surface in front of the user's feet. Many users who try to get on the escalator 2 unconsciously turn their line of sight to their feet in order to confirm their feet. Therefore, by displaying on the floor surface in front of the feet in this way, it is possible for the user himself to visually and clearly recognize the attention information.

  Further, in the case of a two-seater escalator 2, when the escalator 2 is displayed on the inner side surface of the escalator 2, there is a problem that it cannot be visually recognized because it is blocked by other users. There is no problem.

  Further, as in the present embodiment, it is possible to detect that the user is a combination of an adult and a child by collectively determining the number of users together with the attributes of the individual users such as adults and children. Therefore, by applying to the notification information display device 1 installed at the entrance/exit of the escalator 2 or the entrance/exit of a vehicle at an amusement park, the alert information can be made more suitable for the user.

Further, by using the projection display, it is possible to display in accordance with the line of sight of the user, such as the wall surface in the front in the traveling direction, in addition to the floor surface as in the present embodiment, and the degree of freedom of display is high. Moreover, even if the floor surface or wall surface is dirty, dust is dropped, or water is spilled, it is possible to display without any problem.
<Modification>
In the present embodiment, the alert information, which is the notification information, is determined by using both the number of users and the attribute, but either the number of users or the attribute may be used. That is, the display content determination unit 16 included in the notification information determination unit determines whether the attribute determined by the attribute determination unit 14 or the number of persons determined by the number of persons determination unit 12 is at least one of the conditions for determining the notification information. It may be any configuration that uses information.

  In addition, although the age group is used as the attribute in the present embodiment, various attributes that can be discriminated such as gender, foreigner, physique, clothes (wearing kimono?), and the like are combined with each other. Can be used. For example, if it is determined that the user's attribute is a young woman wearing a kimono, it is possible to display alert information such as "please be careful of your kimono sleeves and feet." As the kimono worn by young women is supposed to be furisode, such alert information is effective.

Further, in the present embodiment, since the notification information display device 1 installed at the entrance of the escalator 2 is illustrated, the age group is used as the attribute of the user, and the alert information is raised as the notification information.
However, for example, in the case of the notification information display device 1 installed at the entrance/exit of a commercial facility, the gender is determined as the attribute of the user together with the age group, and the front of the foot of the user passing through the entrance is divided into the gender and the age group. You may make it project and display the image of the guidance display which guides to the sales floor of the corresponding product.

  In addition, the number of users is determined together with the above attributes, and in the case of a combination of an adult and a child, the department for children's clothes and toys is guided, and in the case of an adult, the department suitable for age group and sex is guided. It is preferable that the image of the guide display is a pattern including not only characters but also arrows and the like that can be grasped instantly.

  Further, in the present embodiment, the configuration in which the imaging device 4 and the control device 10 are mounted on the notification information display device 1 together with the projection device 5 has been illustrated. However, the imaging device 4 and the control device 10 may be provided separately from the projection device 5. In that case, the imaging device 4, the control device 10, and the projection device 5 exchange imaging data and control signals using a communication function. When the projection device 5 is a projector device, the projection image data is also transmitted from the control device 10 to the projection device 5. By configuring the projection device 5 with a projector device, various images can be projected.

[Embodiment 2]
In the present embodiment, as one aspect of the notification information display system of the present disclosure, a notification information display device 1A installed at an entrance/exit of an escalator is exemplified. The difference between the notification information display device 1 and the notification information display device 1A of the first embodiment is that the notification information display device 1A has a function of detecting the moving speed of the user and moving the projection position according to the moving speed of the user. The point is to prepare.

  FIG. 7: is a figure which shows the switching of the display position of the notification information display apparatus 1A of another aspect of this invention provided in the entrance of an uphill escalator. FIG. 8 is another diagram showing switching of the display position of the notification information display device 1A.

  As shown in FIGS. 7 and 8, the notification information display device 1A displays the projected image while moving the position (projection position) of the projected image from the position P1 to the position Pn according to the moving speed of the user. The position P1 is a position upstream of the notification information display device 1A in the traveling direction, and the position Pn is a position downstream of the notification information display device 1A in the traveling direction. Although FIG. 7 and FIG. 8 show three display positions, the display position may be continuously changed from the position P1 to Pn according to the speed of the user.

  FIG. 9 is a block diagram showing a configuration of a main part of the notification information display device 1A. As shown in FIG. 9, the notification information display device 1A includes an imaging device 4A in place of the imaging device 4 and a projection device 5A in place of the projection device 5. In addition, the control device 10 includes a projection control unit 18A instead of the projection control unit 18, and further includes a moving speed determination unit 22.

  The imaging device 4A is a stereo camera capable of simultaneously shooting from a plurality of different directions. Even with the imaging device 4 which is not a stereo camera, the moving speed of the user can be determined by comparing the image data taken at different times, but the processing is complicated and the accuracy of the stereo camera is not obtained. .. Therefore, by using the imaging device 4A including the stereo camera in this manner, the moving speed of the user who approaches the entrance can be easily and accurately obtained.

  The moving speed determination unit 22 determines the moving speed of the user based on the imaged data taken by the imaging device 4A. When there are a plurality of users, the moving speeds are almost the same, so the moving speed of the first user may be calculated.

  The projection device 5A can switch the projection position of the image on the floor from the position P1 to the position Pn, as shown in FIG. Specifically, the projection device 5A includes a movable mechanism and is configured to change the projection direction. By changing the projection direction, the distance between the projection device 5A and the projection surface such as the floor changes, but it can be displayed in a just focus by using the laser light source.

  The projection control unit 18A controls the drive of the projection device 5A according to the moving speed of the user determined by the moving speed determination unit 22, and sets the projection position so that the projected image is displayed in front of the feet of the user. To move.

  FIG. 10 is a flowchart showing the operation of the notification information display device 1A. 6 is different from the flowchart of FIG. 6 in that moving speed determinations S21 and S22 are provided between S3, S4, and S5, and S7 to S11 and S12 are different from the processing for determining the end of image display in S23. There is provided processing for moving the projection position according to the moving speed of the user.

The notification information display device 30 projects and displays, as an image of the notification information, an image of the passability information indicating whether the passage is possible. It should be noted that in the case of the notification information display device 30 installed at the entrance/exit, notification of the passability information is essential, but as described above, the image pickup device 4 (4A) is used to determine the attributes and the number of users. Then, the alert information and the guide display information based on the attributes and the number of users may be displayed alternately with the pass/fail information or after the pass/fail information.

  FIG. 12 is a diagram showing a notification information display device 30 according to one aspect of the present invention provided at the entrance to a dedicated floor and a state when the notification information is displayed. As shown in FIG. 12, the notification information display device 30 has a wall-shaped portion 40 that is arranged along the traveling direction, and on the top surface of the wall-shaped portion 40, as a user recognition unit that recognizes a user individually. The biometric authentication device 31 is provided. The biometric authentication device 31 reads a vein of a user's wrist or finger, for example, to identify an individual. It suffices if the individual user can be identified from the living body. The reading unit of the biometric authentication device 31 may be provided on the top surface of the wall-shaped unit 40.

  Although the example of FIG. 12 illustrates a configuration in which the pair of notification information display devices 30 are installed with one wall facing each other at one entrance, only one notification information display device 30 is provided at one entrance. Installed, one side may be just a wall.

  The notification information display device 30 projects and displays an image of passability information, which is the notification information, on the floor surface in front of the feet of the user who is going through the entrance. In the present embodiment, the display areas of the notification information display devices 1 arranged on the left and right are overlapped, and one of the notification information display devices 30 that has read the user by the biometric authentication device 31 displays the pass/fail information. Project the image.

  FIG. 12 shows a state in which an image E indicating that passage is not possible is projected and displayed as a result of the biometric authentication device 31 of the notification information display device 30 on the left side in the traveling direction reading a user (not shown). There is. In the example of FIG. 12, a trick picture (trick image) is used in which a user who visually recognizes the projected image E sees the bump E standing upright so as to block the entrance so that he/she may suddenly stop. FIG. 12 shows a state of the bump E that is viewed three-dimensionally by the user. This makes it possible to clearly recognize that passage is not possible, so it does not physically restrict passage like a door, but it plays a role like a door and can be used from a card gate or a ticket gate. Can meet the needs of abolishing.

  FIG. 13 is a block diagram showing a configuration of a main part of the notification information display device 30. As shown in FIG. 13, the notification information display device 30 includes a biometric authentication device 31, a communication device 37, and a control device 32.

  The passability determination unit 33 determines whether or not the user can pass through the entrance based on the result recognized by the biometric authentication device 31. In the present embodiment, the passability determination unit 33 sends the biometric data read by the biometric authentication device 31 to the communication control unit 38. The biometric data is transmitted to an external server or the like via the communication device 37. The external server stores biometric data of a passable user, and the passability determination unit 33 receives the passability information from the server or the like and determines the passability.

  The display content determination unit 34 refers to the display image table 35 based on the determination result of the passability determination unit 33 and determines the display content to be projected and displayed as the image of the passability information. Various images including the image E shown in FIG. 12 are stored in the display image table 35. The projection control unit 18 controls driving of the projection device 5 to project and display the display content determined by the display content determination unit 34.

  The biometric authentication device 31 and the passability determination unit 33 of the control device 32 constitute an information acquisition unit that acquires information of the user from a user who intends to pass through the passage area. Further, the display content determination unit 34 and the display image table 35 of the control device 32 constitute a notification information determination unit that determines the notification information to notify the user based on the information obtained by the information acquisition unit. Also in this case, the display content determination unit 34 that constitutes the notification information determination unit may be configured to use the information indicating the passability determined by the passability determination unit 33 as at least one of the conditions for determining the notification information. Good.

  As described above, it is possible to visually recognize the image three-dimensionally by using the trick picture. As a result, for example, it is possible to enhance the display effect by urging the user to pay attention to the projected pattern rather than the characters such as "I cannot pass!" and "Prohibition of passing!" ..

  In addition, by displaying the image E so that it can be visually recognized even by a user who is going to pass through the entrance from immediately behind (the upstream side in the traveling direction) of a user who cannot pass, a user who tries to pass without observing the regulation. It acts as a deterrent to the vehicle, and can prevent illegal traffic even without a door that opens and closes depending on whether or not the vehicle can pass.

  The image of the fake picture showing that it cannot pass is not limited to the image E that looks like a bump, but it is an image with a hole in front of the footsteps, or a large x mark standing up to block the entrance. Any image may be used as long as it can stop the user and recognize that it is restricted.
