[0026] [First embodiment] A first embodiment of the present invention will be described below with reference to FIGS. Fig. 1 is an external perspective view of the image display device main body of the first embodiment. Figs. 2, 3, and 4 are front, back, and cross-sectional views of a display unit having an equilateral triangular outline, Figs. 5, 6, and 7 are front, back, and cross-sectional views of a display unit having an equilateral pentagonal outline, and Fig. 8 is a view showing the inside of the image display device divided into two from the state shown in Fig. 1. Fig. 9 is a block diagram showing the configuration of a system equipped with a control device that controls the image display device.

[0027] The image display device main body 1 of the first embodiment shown in Fig. 1 has the appearance of a icosidodecahedron, which is a uniform polyhedron. The image display device main body 1 is configured by combining 20 equilateral triangular display units 2 shown in Figs. 2, 3, and 4 with 12 equilateral pentagonal display units 3 shown in Figs. 5, 6, and 7. The lengths of the sides of the equilateral triangle and the regular pentagon are equal. In Fig. 1, the part that corresponds to a hemisphere and is divided vertically into two halves by a horizontal plane in the vertical center is joined by one side of the equilateral triangular display unit 2 and one side of the regular pentagonal display unit 3. Each of the display units 2 and 3 has a flat surface 2a, 3a whose faces are regular polygons that form an icosidodecahedron, and an inner peripheral surface concentric with the icosidodecahedron. one The individual display surfaces 2b, 3b have the same curvature and constitute a single spherical surface when all the image display units 2, 3 are assembled to form an icosidodecahedron.

[0028] Figure 8 is a diagram showing the hemispherical display surface that is the upper half of the image display device main body 1 in Figure 1. As shown in the figure, inside the image display device main body 1, there are arranged a display surface 2b of an equilateral triangular display unit 2 and a display surface 3b of a regular pentagonal display unit 3, which together form a spherical surface.

[0029] Furthermore, a sensor S, which is a position identification means, is attached to each of the display units 2 and 3. This sensor S is attached between the surface 2a and the display surface 2b of the display unit 2, and between the surface 3a and the display surface 3b of the display unit 3, and is built into each of the display units 2 and 3. This sensor S detects the orientation of the surfaces 2a and 3a of the display units 2 and 3. Here, the surfaces 2a and 3a 、 The data consisting of the tilt angle from a reference plane, for example, a horizontal plane, and the orientation (the direction in which the surface is facing) is referred to as the orientation of the surfaces 2a and 3a. The sensor S is configured, for example, by a 9-axis motion sensor.

[0030] Furthermore, display unit 2 has a coupling surface 2c along the outline of an equilateral triangle between surface 2a and display surface 2b, and similarly, display unit 3 has a coupling surface 3c along the outline of a regular pentagon between surface 3a and display surface 3b. The connecting surfaces 2c, 3c are flat surfaces, and each connecting surface 2c, 3c is provided with a connecting means (not shown) that enables the connecting surfaces 2c, 3c to be attached and detached to each other. The connecting means is provided with a positioning mechanism using, for example, guide pins and guide holes, enabling accurate positioning of the display units 2, 3. Furthermore, the connecting means of one display unit 2, 3 is configured to be connectable to the connecting means of any other display unit 2, 3.

[0031] FIG. 9 shows an example of a system for displaying a spherical image on the image display device main body 1 described above. As described above, this embodiment includes the image display device main body 1, which is formed into an icosidodecahedron by connecting a total of 32 display units 2, 3, a host computer PC that transmits images to be displayed to the image display device main body 1, and an image database D that stores spherical images. The host computer PC includes a data processing unit 101 and a data storage unit 102. The data storage unit 102 stores the shape of the image display device main body 1 and the orientation information of the surfaces of the display units 2 and 3.

[0032] The data storage unit 102 also stores divided image data to be displayed on the display surfaces 2b and 3b of the display units 2 and 3. The divided image data refers to images obtained by dividing the spherical image to be displayed into regions for the individual display surfaces 2b and 3b. As shown in Figure 8, the display surface 2b of the equilateral triangular display unit 2 and the display surface 3b of the equilateral pentagonal display unit 3 are arranged inside the polyhedron to form a spherical surface. Divided images corresponding to the display areas of the display surfaces 2b and 3b are created so that the spherical image is displayed as a whole.

[0033] On the other hand, the display unit 2 includes a data processing unit 201 linked to the sensor S, a data storage unit 202, and a display unit 203 linked to the display surface 2b. Similarly to the display unit 2, the display unit 3 also includes a data processing unit 301, a data storage unit 302, and a data display unit 303. The display units 2 and 3 are each capable of communicating with the host computer PC via a communication module (not shown). Any type of communication module may be used, but a wireless connection is preferred, which eliminates the need for communication wiring between the host computer PC and each of the display units 2 and 3.

[0034] Furthermore, among the regular polygons that make up the 20-12 polyhedron, for example, a pair of vertically connected equilateral triangles and regular pentagons can be removed to form an entrance / exit for visitors. The entrance can be designed to close after the visitor enters, or it can be left open.

[0035] [Actions and effects] Next, a procedure for producing the image display device main body 1 and displaying a specific spherical image will be described. The 20 equilateral triangular display units 2 and 12 equilateral pentagonal display units 3 are combined to assemble the 20-12 polyhedron shown in Figure 1. In this case, the display units 2 and 3 can be arranged according to the shape of the completed polyhedron, and there is no need to consider the arrangement of display units 2 and 3 of the same shape.

[0036] The reason why the polyhedron can be assembled in this way without having to worry about the detailed positions of the display units 2 and 3 will be explained below. First, the icosidodecahedron is assembled and placed so that the surface 3a of one display unit 3 faces the bottom, as shown in FIG.

[0037] Once the polyhedron is formed, the sensor S of each display unit 2, 3 is activated, and the sensor S detects the orientation data of the surfaces 2a, 3a of that display unit. The orientation data of the surfaces is, for example, orientation data p including the angle from the bottom surface (horizontal plane) and the orientation of the surfaces. This orientation data p corresponds one-to-one with the surfaces 2a, 3a, and no two surfaces 2a, 3a of the 20-12 polyhedron are the same. Therefore, the position of each display unit 2, 3 on the polyhedron can be identified by the orientation data p of the surfaces. The posture data corresponding to each surface is represented as p1, p2, . . . , p32, and each display unit 2, 3 stores posture data pn indicating the posture of its own surface in the data storage unit 202, 302.

[0038] On the other hand, in the host computer PC, the data storage unit 102 stores the face orientation data p1, p2, . . . , p32 of the surfaces 2a, 3a of the icosidodecahedron that is the external shape of the image display device main body 1. The data processing unit 101 also retrieves data of the spherical image to be displayed from the image database D, and creates 32 pieces of divided image data by dividing the data into display areas for each of the display surfaces 2b, 3b, ... of the icosidodecahedron. In other words, the data processing unit 101 functions as an image data processing means for creating divided image data. Each piece of divided image data is then associated with orientation data pn of the surfaces 2a, 3a corresponding to the display surfaces 2b, 3b on which it should be displayed, and the data is stored in the data storage unit 102.

[0039] The host computer PC transmits all the divided image data associated with the surface attitude data pn to the display units 2 and 3. The data processing unit 201, 301 of each image display unit 2, 3 selects the divided image data associated with its own attitude data pn stored in the data storage unit 202, 302 from the divided image data transmitted from the host computer PC. The data processing unit 201, 301 of the display unit 2, 3 then transmits the selected divided image data to the display unit 203, 303, which displays it on the display surface 2b, 3b. This allows spherical images to be displayed on the multiple display surfaces 2b, 3b.

[0040] As described above, each display unit 2, 3 is equipped with a sensor S that detects the orientation of its own surface, so when assembling the polyhedron, there is no need to consider the detailed arrangement of each display unit in order to correctly display a spherical image using multiple divided images, simplifying the work of forming the image display device main body 1. Furthermore, since the unit can be disassembled using the connecting means, it is easy to transport and change the installation location.

[0041] In the above description, the data processing unit 101 of the host computer PC creates the divided image data and associates the surface orientation data with the divided image data, and creates the divided image data and associates the orientation data with it every time a spherical image is acquired. However, the divided image data associated with the orientation data may be created in advance and stored in the image data storage unit 102. Alternatively, the divided image data may be saved in the image database D, and the host computer PC may simply import and transmit it.

[0042] Furthermore, the display units 2, 3 may transmit the attitude data pn of their own surfaces to the host computer PC in association with a unit ID that identifies each display unit 2, 3, and the data processing unit 101 of the host computer PC may select the divided image data corresponding to the attitude data pn of the display units 2, 3 from the data storage unit 102 and transmit only the divided image data corresponding to one of the attitude data pn to the display units 2, 3 corresponding to the attitude data pn. In this case, the display units 2, 3 may simply display the received divided image data. Although the sensor S that detects the orientation of the surface is used as the means for identifying the position of each display unit 2, 3 in the above, a sensor that identifies the three-dimensional coordinates of each surface may also be used. Since no two surfaces in a single polyhedron have the same three-dimensional coordinates, the divided image data to be displayed can be identified by the identified three-dimensional coordinates.

[0043] Furthermore, if a spherical image capturing device, such as a camera equipped with a fisheye lens, is connected to the host computer PC instead of the image database D, the captured spherical images can be displayed while capturing them. In this case, the data processing unit 101 of the host computer PC creates divided image data from the input captured images and transmits them to the display units 2 and 3. For example, if a spherical image captured by a drone or the like is displayed in real time, the viewer can experience the sensation of flying.

[0044] [Second embodiment] The image display device main body 4 of the second embodiment shown in Fig. 10 is an icosidodecahedron, but differs from the first embodiment shown in Fig. 1 in the arrangement of the connecting portions of the portions corresponding to the upper and lower hemispheres divided by a regular decagonal plane. In the second embodiment, equilateral triangular display units 2, 2 and regular pentagonal display units 3, 3 are connected at the boundary surface between the upper and lower portions. The icosidodecahedron constituting the image display device main body 4 has vertices along the boundary surface that have different shapes from the other vertices, and although it is not a uniform polyhedron, the upper and lower portions maintain symmetry.

[0045] The other configurations are the same as those of the first embodiment, and therefore detailed explanations will be omitted. In this second embodiment, for example, a pair of vertically adjacent equilateral triangular display units 2, 2 can be removed to form a diamond-shaped entrance / exit. Furthermore, among the regular pentagonal display units 3 having a larger display area than the equilateral triangular display unit 2, the vertically continuous regular pentagonal display units 3, 3 are positioned in front of the viewer, making the outlines of the display units 2, 3 less noticeable to the viewer, allowing the viewer to view the front image more comfortably.

[0046] [Third embodiment] The third embodiment shown in FIG. 11 includes viewer seats 5 and 6 and a floor material 7 on which they are placed inside the image display device main body 4 of the second embodiment. After the image display device main body 4 is assembled, the components of the viewer seats 5, 6 and floor material 7 are carried into the image display device main body 4 through an entrance of the image display device main body 4 and are formed inside. The floor material 7 is a transparent plate, and the viewer can see the image displayed on the display surface 3b of the display unit 3, which is located under the viewer's feet, from the viewer's seats 5 and 6. Such viewer's seats 5 and 6 and floor material 7 can be provided not only in the third embodiment, but also in the image display device of the first embodiment or other embodiments.

[0047] Moreover, instead of the floor material 7 made of the transparent plate, a perforated plate such as a punched metal or a mesh metal may be used. In this embodiment, the specific display unit 3 that forms the bottom surface is provided with mounting parts for attaching the viewer seats 5, 6. Therefore, not all regular pentagonal display units 3 have exactly the same configuration. However, because the mounting parts allow the display unit 3 placed on the bottom surface to be uniquely identified from other display units, the presence of a display unit 3 for the bottom surface does not complicate the assembly work.

[0048] [Fourth embodiment] 12 is a front view of the appearance of an image display device main body 8 of the fourth embodiment. The image display device main body 8 can display a hemispherical image in a shape obtained by dividing the image display device main body 1 of the first embodiment into two parts along a horizontal plane in the center in the vertical direction. The other configurations are the same as those of the first embodiment. Therefore, in this fourth embodiment as well, the image display units 2 and 3 can be assembled and disassembled, and can be easily installed in various locations.

[0049] [Other embodiments] Although the above description has been given of a polyhedron having an icosidodecahedron as its basic shape, the polyhedron constituting the image display device of this invention is not limited to an icosidodecahedron. If the polyhedron is surrounded by two or fewer types of regular polygons, the shape of each display unit will be two or fewer types, making assembly easier. For example, if the display is a regular polyhedron such as a regular icosahedron or a regular octahedron, all display units will be equilateral triangles, making it easier not only to assemble but also to store after disassembly. Furthermore, with a uniform polyhedron or a highly symmetrical polyhedron such as the image display device main body 4 shown in Figure 10, it is easy to make the display surface spherical, and even if the display surface is flat, a spherical image can be displayed without creating an unnatural feeling.

[0050] However, the only polyhedrons that can be divided into two hemispheres (halves) along the outline of the display unit are the regular octahedron and the icosidodecahedron. Therefore, when creating an image display device that is compatible with both full spheres and hemispheres, it is preferable to use a regular octahedron or an icosidodecahedron as the basic shape. If another polyhedron is used as the basic shape, the inside of the display unit must be cut to form a hemisphere.

[0051] 13, the image display device main body 9, which has a regular octahedron as its basic shape, is composed of eight equilateral triangular display units 10. Like the other display units 2 and 3, the display unit 10 is equipped with a sensor S, and is formed so that the display surface, which is the inner peripheral surface, is a sphere centered at the center of the regular octahedron. By using a support base 11 as shown in the figure, this image display device main body 9 can arrange the vertices vertically so that the regular octahedron can be divided into two halves, top and bottom.

[0052] In the above embodiment, the display surface of each image display unit, which is the inner peripheral surface of the polyhedron, is spherical. However, the display surface may also be a flat surface parallel to the regular polygon of the surface. If the display surface is flat, the closer to the outer edge of the display surface, the more distortion appears in the displayed image. However, the smaller the display area of ​​each display unit, the more natural the spherical surface can be displayed. Therefore, considering the display quality of the spherical image, it is preferable to use a polyhedron with a large number of surfaces as the basis. On the other hand, if the number of surfaces of the polyhedron is large, the number of display units will also increase, which may make the assembly process more complicated.

[0053] Therefore, when the display surface is to be a flat surface, it is important to select a standard polyhedron taking into consideration image quality, ease of assembly, transportability, and the like. However, if the display surfaces 2b and 3b are spherical as in the above embodiment, images can be displayed on the sphere regardless of the number of faces of the polyhedron, which increases the degree of freedom in selecting the basic polyhedron.

[0054] Alternatively, all display units 2 and 3 may have built-in speakers, and after assembly, only the speakers in the necessary positions may be activated. The speakers to be activated can be determined based on the orientation data of the surface, just as when determining the divided images to be displayed, and their placement can achieve stereophonic sound. The spherical image displayed on the image display device of the present invention includes moving images and still images, and includes not only full-spherical and hemispherical images but also partial images thereof. [Industrial Applicability]
