  FIG. 1 is a diagram illustrating the structure of a reverse running and erroneous approach prevention system according to the first embodiment. The reverse running and erroneous approach prevention system 1 mainly includes intruders other than a predetermined authorized person such as an automobile exclusive road, an expressway road, and a general road (for example, a pedestrian 200 erroneously entering an automobile exclusive road or a vehicle that runs backward). 2 driver), etc., to be aware of inappropriate movement (reverse running, pedestrian erroneous entry, etc.). The reverse running and erroneous approach prevention system 1 includes a reverse running and erroneous approach prevention device 100 provided at a reverse running prohibition point or an entry prohibition point.

  In the reverse running and erroneous approach prevention device 100, the display device 40 and the aerial imaging plate 30 are arranged in the gap so as to form a predetermined angle 50B. The reverse running and erroneous approach prevention device 100 is embedded in the road 70.

  The display device 40 emits and outputs display information for preventing reverse running and erroneous entry (for example, “X (X)” mark, “Tare” character, or road sign indicating entry prohibition)). For example, the display device 40 is a liquid crystal display, an organic EL display device, or a high brightness LED sign.

  The aerial imaging plate 30 is an aerial imaging means including an optical system that reflects light emitted from the display device 40 by a predetermined method to form the real image 10 at a predetermined aerial position. The aerial imaging plate 30 is preferably embedded substantially parallel to the pavement surface of the road 70. Further, it is desirable to provide a protective surface with transparency to the upper surface of the aerial imaging plate 30 to such an extent that it does not hinder light transmission, such as acrylic, resin, tempered glass and the like.

  By doing in this way, the display content displayed on the display device 40 is stereoscopically viewed from the road 70 at an angle of 50A when viewed from the pedestrian 200 (it appears to be raised). In the present embodiment, the aerial imaging plate 30 is raised by an angle 50A equal to the angle 50B formed with the display device 40 to form the real image 10. Such an aerial imaging plate 30 is realized by a known technique using, for example, a plate that forms a three-dimensional image with orthogonal reflecting surfaces.

  As the aerial imaging plate 30, for example, a special panel made of glass or resin manufactured by Ascarnet Co., Ltd., which is called AI plate (registered trademark), can be used. With this eye plate, a real image of an entity can be formed in the air at an equal distance on the opposite side across the eye plate, and if a video monitor is installed at a fixed location, still images and videos displayed there Is imaged as a two-dimensional image. In addition, the eye plate similarly forms a three-dimensional image on the opposite side by placing a three-dimensional object as an entity. In the present embodiment, the real image 10 is obtained by adopting so-called passive aerial imaging in which a copy of the entity is received in this way and the copy is aerial imaged. In addition, so-called active aerial imaging such as a laser is not appropriate because it may interfere with the field of view of a forward traveling vehicle.

  In the reverse running and erroneous approach prevention device 100, the display device 40 may be provided with a variable angle 50B formed with the aerial imaging plate 30. Further, the reverse running and erroneous approach prevention device 100 may include a drive unit that applies a driving force such as a stepping motor that moves the display device 40 to change the angle 50B. By doing so, the angle 50B can be made variable, so that the angle at which the real image 10 rises can be easily adjusted, and the maintenance load can be greatly reduced.

  Further, in the reverse running and erroneous approach preventing device 100, the aerial imaging plate 30 may be provided with an angle 50B formed with the display device 40 variably. Further, the reverse running and erroneous approach prevention device 100 may include a driving unit that applies a driving force such as a stepping motor that moves the aerial imaging plate 30 to change the angle 50B. By doing so, the angle 50B can be made variable, so that the angle at which the real image 10 rises can be easily adjusted, and the maintenance load can be greatly reduced. In general, since the aerial imaging plate 30 is smaller in mass than the display device 40, the drive unit for moving can be made simpler.

  The reverse running and erroneous entry prevention system 1 according to the first embodiment has been described above. According to the reverse running and erroneous approach prevention system 1, the pedestrian 200 or the driver of the vehicle 2 running backward can visually recognize the solid three-dimensional real image 10 output by the reverse running and erroneous approach prevention system 1. Even in situations where it is difficult to ensure visibility at night or the like, it is easy to see, and it is possible to efficiently call attention to prevent reverse running and erroneous entry. Further, since the real image 10 cannot be viewed from the opposite side (the right side in FIG. 1) (out of the range of the viewing angle), the driver of the forward running vehicle does not have to be aware of the existence of the real image 10. Contact with 10 does not cause physical contact.

  FIG. 2 is a diagram illustrating an operational image of the reverse running and erroneous approach prevention system 1 according to the first embodiment. When the reverse running and wrong approach prevention system 1 is applied to the reverse running of the vehicle and the wrong approach prevention, the driver of the vehicle 2 running backward will see the real image 10 on the road in the traveling direction when the traveling direction is prohibited. Can be viewed three-dimensionally. As an example of a more specific road situation, as shown in FIG. 2, when the straight direction of the intersection is an entry prohibition direction such as an exit ramp of an expressway, the driver has a real image on the road in the straight direction. 10 can be seen three-dimensionally. Therefore, the driver can easily notice the display 21 of the in-vehicle device indicating that a route other than straight ahead should be taken at the intersection. This is because the surroundings are often dark especially during night driving, and the real image 10 emits light, thereby increasing the visibility.

  FIG. 3 is a diagram illustrating an operation image of the reverse running and erroneous approach prevention system according to the second embodiment. In the second embodiment, in the reverse running and erroneous approach prevention system 1 ′, the reverse running and erroneous approach prevention device 100 ′ is provided on the road shoulder, and the aerial imaging plate is substantially perpendicular to the road paved surface and the road. It is provided along the extending direction (longitudinal direction). For this reason, the real image 10 ′ is projected (imaged) horizontally on the road from the reverse running and erroneous approach prevention device 100 ′. As a result, the driver can view the real image 10 'at a height closer to the height of the line of sight. In addition, laying work can be simplified since the burying in the road 70 is not required even when the reverse running and erroneous entry preventing device 100 ′ is arranged.

  FIG. 4 is a diagram illustrating the structure of the reverse running and erroneous approach prevention system according to the second embodiment. In FIG. 4, a diagram in which the inside of the reverse running and erroneous approach preventing device 100 ′ is seen through from above is connected to a diagram in which the side surface of the reverse running and erroneous approach preventing device 100 ′ is viewed from the road side. .

  The main surface of one or a plurality of aerial imaging plates 30 ′ A to 30 ′ C is provided on the side surface of the reverse running and erroneous approach prevention device 100 ′ so as to be seamlessly aligned with the road 70 in the direction in which the road extends. It is done. In this figure, an example of three aerial imaging plates is shown, but the number is not limited to this, and it goes without saying that the number of images is appropriately increased or decreased according to the size of the real image 10 ′ to be output. Yes.

  Inside the reverse running and erroneous entry prevention device 100 ′, a pedestal 41 that can freely move in two orthogonal axes on a horizontal plane, and a main display surface that is inclined on the road direction at a predetermined angle are arranged on the pedestal 41. And a control unit 110 that supplies power and display information to the display device 40 '. Further, as guide rails for sliding the pedestal 41 in two orthogonal directions on the horizontal plane, guide rails 120A and 120B are provided in the first axial direction, and guide rails 130A and 130B are provided in the second axial direction, respectively. . The display device 40 ′ itself is also provided on the pedestal 41 via a hinge or the like, and can be turned on the pedestal 41 at an elevation angle of about 10 degrees and a left-right deflection angle of about 45 degrees. Further, the turning operation and the sliding operation may be driven by a driving unit such as an actuator.

  By using such reverse running and erroneous approach prevention device 100 ', reverse running and erroneous approach prevention system 1' according to the second embodiment can be realized. Further, the display angle of the real image 10 ′, the display size, and the like are adjusted by the turning operation and sliding operation of the display device 40 ′ and the arrangement and size of the aerial imaging plates 30 ′ A to 30 ′ C.

  The above is the reverse running and erroneous entry prevention system 1 ′ according to the second embodiment. According to the second embodiment, the driver can visually recognize the real image 10 ′ at a height closer to the height of the line of sight. In addition, laying work can be simplified since the burying in the road 70 is not required even when the reverse running and erroneous entry preventing device 100 ′ is arranged.

  FIG. 5 is a diagram illustrating a structure of a reverse running and erroneous approach prevention system according to a modification. In FIG. 5, as a modified example of the reverse running and erroneous approach prevention system 1 according to the first embodiment, a reverse plate provided with a transmission plate 310 that is superimposed on the aerial imaging plate 30 and that enlarges and transmits display information. A running and false entry prevention system 300 is shown. In such a modification, light emitted from the display device 40 is transmitted through the aerial imaging plate 30 and the transmission plate 310 to form a real image 320. Since the image is enlarged when passing through the transmission plate 310, a real image 320 larger than the display device 40 can be obtained.

  Even in this case, the angle 50A at which the real image rises is the same as the angle 50B formed by the display device 40 and the aerial imaging plate 30. In FIG. 5, the transmission plate 310 is superimposed on the aerial imaging plate 30, but is not limited thereto, and is provided between the display device 40 and the aerial imaging plate 30. May be used.

  FIG. 6 is a diagram illustrating an operation image of the reverse running and erroneous approach prevention system according to the modification. When the reverse running and wrong approach prevention system 300 is applied to the reverse running and wrong approach prevention of the vehicle, the driver of the vehicle 2 that runs backward is more realistic on the road in the traveling direction when the traveling direction is prohibited. Can be viewed three-dimensionally. As an example of a more specific road condition, as shown in FIG. 6, when the straight direction of the intersection is an entry prohibition direction such as an exit ramp of an expressway, the driver greatly moves on the straight road. The real image 420 can be viewed three-dimensionally. Therefore, the driver is more easily aware of the display 21 of the in-vehicle device that indicates that a route other than straight driving should be taken at the intersection. This is because, especially when driving at night, the surroundings are often dark, and the real image 420 emits a large amount of light so that the visibility becomes higher.

  FIG. 7 is a diagram illustrating a structure of a reverse running and erroneous approach prevention system according to another modification. In FIG. 7, as another modified example of the reverse running and erroneous approach prevention system 1 according to the first embodiment, a transmission plate 510 that overlaps the aerial imaging plate 30 and bends and transmits display information is provided. A reverse running and false entry prevention system 500 is shown. In such a modification, the light emitted from the display device 40 is transmitted through the aerial imaging plate 30 and the transmission plate 510 to form a real image 520. Since the image is bent when passing through the transmission plate 510, a real image 520 that rises at an angle 530 larger than the angle 50 </ b> B formed by the display device 40 with the aerial imaging plate 30 can be obtained.

  In FIG. 7, the transmission plate 510 is superimposed on the aerial imaging plate 30, but is not limited thereto, and is provided between the display device 40 and the aerial imaging plate 30. May be used.

  FIG. 8 is a diagram illustrating an operation image of the reverse running and erroneous approach prevention system according to the modification. When the reverse running and erroneous approach prevention system 500 is applied to the reverse running and erroneous entry prevention of the vehicle, even if the driver of the vehicle is located farther from the intersection than the vehicle 2, the traveling direction is prohibited. In addition, a real image that stands up more clearly on the road in the traveling direction can be seen three-dimensionally. As a more specific example of the road situation, as shown in FIG. 8, even if the driver of the vehicle 602 is located farther from the intersection than the vehicle 2, the straight road direction of the intersection is the exit ramp of the highway. The driver can view the real image 620 that stands up more clearly on the road in the straight direction in a three-dimensional manner. Therefore, the driver is likely to notice the display 21 of the in-vehicle device indicating that the route other than the straight traveling should be taken at the intersection at an earlier stage. This is because, especially when driving at night, the surroundings are often dark, so that the real image 620 emits light so that it can be seen from a distance, thereby increasing the visibility.

  The reverse running and erroneous approach prevention systems according to a plurality of embodiments have been described above. However, the present invention is not limited to this embodiment, and various modifications may be made. For example, with respect to the reverse running and erroneous approach prevention system according to the first embodiment of the present application, an infrared or visible light image that detects an object approaching within a predetermined distance from a position to be notified of reverse running and erroneous entry prevention is used. When the detection device detects an object, the display device emits and outputs display information for preventing reverse running and erroneous entry, and the aerial imaging plate emits light from the display device for a predetermined amount. The image may be reflected by a method to form an image at a predetermined aerial position. By doing in this way, the power consumption of a display apparatus can be suppressed and deterioration of a display apparatus can be suppressed.

  In addition, for example, as described above, a detection device using an infrared or visible light image for detecting an object approaching within a predetermined distance from a position where notification of reverse running and prevention of erroneous entry is desired is provided, and the detection device detects an object. If the detected object is a pedestrian or a vehicle, the display device identifies the size and angle of the display information for preventing reverse running and erroneous entry according to the pedestrian or vehicle. The aerial imaging plate may be configured to reflect light emitted from the display device by a predetermined method and form an image at a predetermined aerial position. By doing in this way, in the case of a pedestrian, measures, such as suppressing an excessive display, can be performed.

  In addition, for example, in the reverse running and erroneous approach prevention system in the above embodiment, the aerial imaging plate 30 is used as a method for imaging in the air, but is not limited thereto. For example, as shown in FIG. 9, aerial imaging may be realized by combining a retroreflecting material 720 and a half mirror 710. FIG. 9 is a diagram showing the structures of the reverse running and erroneous approach preventing device and the reverse running and erroneous approach preventing system according to still another modified example of the first embodiment and the second embodiment and their modified examples. is there. More specifically, light emitted from the display device 40 that emits a sufficient amount of light, such as a high-intensity LED sign, is dispersed by the half mirror 710, reflected by the retroreflecting material 720, and transmitted through the half mirror 710 again. Thus, the real image 730 may be formed in the air with a predetermined angle with respect to the half mirror 710. By doing so, it is possible to realize protection from weathering / deterioration because the recursive reflector 720, which is a material that has a great influence on aerial imaging, is difficult to be exposed by the external environment. The attenuation of the amount of light due to the transmission of the half mirror 710 is not a problem because the display device 40 can secure a sufficient amount of light for visual recognition by using a high-intensity LED sign.

  In the reverse running and erroneous approach prevention device, the aerial imaging plate 30 is an aerial imaging means in which aerial imaging is realized by a combination of the retroreflecting material 720 and the half mirror 710, and is a half mirror. 710 is preferably buried substantially parallel to the road pavement.

  In the reverse running and erroneous approach prevention device, the display device 40 is provided with a variable angle formed with the retroreflecting material 720, and the display device 40 is driven to change the formed angle. A part may be provided.

  In the reverse running and erroneous approach prevention device, the retroreflective member 720 is provided with a variable angle with the display device, and the retroreflective member 720 is driven to change the angle formed. You may provide a drive part.

  Further, in the reverse running and erroneous approach prevention device, the half mirror 710 is provided substantially perpendicular to the road pavement and along the road extending direction, and the retroreflecting material 720 is provided on the road pavement. It is desirable to be perpendicular to the direction of the road and perpendicular to the road.

  Further, the reverse running and erroneous approach prevention device described above may include a transmission plate that enlarges and transmits display information.

  Further, the reverse running and erroneous approach prevention device may include a transmission plate that bends and transmits display information.

  In addition, the reverse running and erroneous approach prevention system includes a reverse running and a display device 40 provided in the ground, an aerial imaging means, and a detection device that detects an object approaching within a predetermined distance. It may be an erroneous entry prevention system. In this system, when the detection device detects an object, the display device 40 emits and outputs display information for reverse running and prevention of erroneous entry, and the half mirror 710 serving as an aerial imaging means and the retroreflection. The optical system made of the material 720 can reflect light emitted from the display device 40 and form an image at a predetermined aerial position.

  The reverse running and erroneous approach prevention method includes reverse running and a display device 40 provided in the ground, an aerial imaging means, and a detection device that detects an object approaching within a predetermined distance. A reverse running and erroneous entry prevention method by an erroneous entry prevention system may be used. In the method, a detection step in which the detection device detects an object, an output step in which the display device 40 emits and outputs display information for preventing reverse running and erroneous entry in response to the detection, and an aerial imaging means The optical system including the half mirror 710 and the retroreflecting material 720 reflects the light emitted from the display device 40 and forms an image at a predetermined aerial position.

  FIG. 10 is a diagram illustrating the structure of a reverse running and erroneous approach prevention system according to still another modification. In FIG. 10, the structure is basically the same as the structure of the reverse running and erroneous approach prevention system according to the first embodiment, but there is a difference in part. Hereinafter, the difference will be mainly described.

  In the reverse running and erroneous approach prevention device 100F, the display device 40 and the aerial imaging plate 30 are provided in the gap, and are embedded in the road 70. The surface 70A, which is a part of a plane constituting the bottom surface of the air gap, is a mirror, glass, or resin wall having a reflectivity sufficient to project the light emitted from the display device 40 onto the aerial imaging plate 30. Alternatively, the surface 70A may be a wall having a mirror surface. The surface 70 </ b> A is not limited to be horizontal, and is preferably parallel to the pavement surface of the road 70.

  The display device 40 is disposed downward toward the surface 70A so as to form the same angle 50C as the predetermined angle 50A with the surface 70A. Thereby, the display content of the display apparatus 40 is reflected once on the surface 70A. Then, the mirror image is projected onto the aerial imaging plate 30, and a real image is formed in the air on the opposite side across the aerial imaging plate 30.

  Thus, by arranging the positional relationship between the display device 40 and the surface 70A, the degree of freedom of the arrangement space is improved. That is, by providing a mirror surface on the optical path from the display device 40 to the aerial imaging plate 30, the mirror surface 70A can reflect the light emitted from the display device 40 toward the aerial imaging plate 30. The degree of freedom of the shape of the reverse running prevention device 100F can be increased.

  In addition, although not shown, for example, in the reverse running and erroneous entry prevention system according to the first embodiment, the display surface of the display device 40 has a transparency that prevents transmission in directions other than the orthogonal direction and limits the viewing angle. You may make it prevent the influence of the contrast fall by disturbance, etc. using a certain polarizing material. Such a polarizing material may be a surface material of the display device 40 itself, a sheet covering the surface, or the like. By doing in this way, the visibility of a real image becomes higher and it can make it easy to call a driver's attention.

  In addition, the reverse running and erroneous approach prevention system in the above-described embodiment is not only a transaction target as a system, but can also be a transaction target with the reverse running and erroneous approach prevention device alone.
