FIG. 2 is a perspective view showing an outline of the virtual indoor space. FIG. 3 is a diagram in which virtual components are arranged in FIG. FIG. 4 is a diagram in which the virtual structure of FIG. 3 is changed.

  A virtual indoor space 20 shown in FIG. 2 is a floor plan of a certain office created as 3D data, and shows a state before arranging components such as a desk and a chair. The included wall surface is drawn as 3D data. The creation of the virtual space by the electronic computer is a known technique, and it is only necessary that the 3D virtual space can be created by the electronic computer in the same manner as the known virtual space creation tool.

  As shown in FIG. 2, the interior of an office, an apartment, a detached house, etc. A structure having at least other wall surfaces in contact with each other, i.e., a structure having at least a floor and two walls intersecting on the corners of the floor is extremely common. Since it is suitable for the present invention and display is performed by the display means 3 having the same structure, it becomes possible to provide a virtual indoor space display device that is very overflowing in both the sense of reality and reality.

  That is, as shown in FIG. 2, the virtual indoor space 20 includes a virtual floor surface 21, a first virtual wall surface 22 that rises vertically in contact with the virtual floor surface 21, and a vertical rise in contact with the virtual floor surface 21, In addition, the second virtual wall surface 23 that is in perpendicular contact with the first virtual wall surface 22 is provided, and the display having the same structure is provided by using the present invention in the virtual indoor space 20 having such a configuration. Since the display is performed by the means 3, the effect is particularly achieved.

  In addition, it is needless to say that the floor plan, the size of the room, the shape, the height of the ceiling, the position of the entrance and the like in FIG. 2 can be freely changed when creating the virtual space.

  In FIG. 3, the user of the present inventor freely arranges virtual components 26 such as a desk 26a, a chair 26b, a shelf 26c, a window 26d, and a display 26e in the virtual indoor space 20 of FIG. Is. As described above, in creating the virtual space, a virtual composition created in advance or created by itself can be freely arranged, or the virtual floor, the first virtual wall, the second virtual wall, and the virtual composition The various conditions such as color, material, and texture are changed.

The number and arrangement are changed.

  Further, the data related to the virtual indoor space 20 including these virtual components 26 can be acquired from another electronic computer 5 via the communication network 6 or a storage medium. It is also possible to create the space 20.

[Shooting in a virtual indoor space]
Shooting of the virtual indoor space 20 when displaying the virtual indoor space 20 on the display means 3 will be described with reference to FIG. FIG. 5 is a view for explaining photographing by the virtual camera in FIG.

  As shown in FIG. 5, when the virtual indoor space 20 is displayed on the display means 3, three virtual cameras 28 (28a, 28b, 28, 28, 28, 28, 28, 28, 28) correspond to the three display means 3 (31, 32, 33). 28c).

  Shooting with the virtual camera 28 is a known technique, and an existing video capturing tool for shooting in the virtual space can also be used, and the first virtual wall surface 22 is shot in the virtual indoor space 20. The first virtual camera 28a, the second virtual camera 28b that captures the second virtual wall surface 23, and the virtual floor surface 21 are respectively high by the third virtual camera 28c near the viewer's eyes of the virtual indoor space display device. Now take a picture.

  For shooting from the height near the viewer's line of sight, for example, the height of the average line of sight of the viewer standing can be taken into consideration, and it can be set to 140 cm to 170 cm. It can be set appropriately such as 90 cm to 110 cm, and it is also possible to set the line of sight from the vicinity of the floor or the line of sight from the vicinity of the ceiling.

  In that case, the projector 31a, 32a, 33a of the display means 3 is arranged so as to be projected so as to match the line of sight of the user of the virtual indoor space display device 1, and image adjustment such as rectangular correction is most prepared. Therefore, it is preferable that the projectors 31a, 32a, and 33a are also installed at the same height as the virtual camera 28.

  The three virtual cameras 28 are extended lines of the optical axes of the three virtual cameras 28 (28a, 28b, 28c) (FIG. 5) so that the user can observe the virtual indoor space with a sense of reality and reality. Are arranged so as to intersect at a common point in front of or behind the three virtual cameras 28.

  In FIG. 5, the extension of the optical axes intersects at a common point behind the three virtual cameras (intersection 27 on the extension line of the optical axis). By arranging the virtual camera 28, there is a virtual viewer at the intersection 27 on the extension line of the optical axis, and the video in the virtual indoor space viewed from the virtual viewer can be displayed on the display means 3.

  Whether the extension lines of the optical axes of the three virtual cameras 28 intersect at a common point in front of or behind the three virtual cameras 28 depends on the setting of the viewing angle of the virtual cameras 28. The display means 3 is appropriately adjusted according to the size of the display means 3 and the range to be displayed. Therefore, if the extension lines of the optical axes of the three virtual cameras 28 intersect at a common point, whether they intersect at the front or rear of the three virtual cameras 28 depends on these conditions. .
