Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image-use simulation apparatus which enables a user to experience a virtual exploration of space exploration, undersea exploration, etc. while seeing an image projected on a video screen.

[0002]

2. Description of the Related Art As a simulation device of this type, an image is projected on a screen according to a predetermined pattern in an indoor hall of a movie theater or the like, and the audience seat is used as a moving seat to move the seat according to the image. Or, I was able to enjoy the real feeling by using stereophonic sound. In addition, recently, there are also ones in which a complex image is made by CG (computer graphics) to entertain a spectator, or each spectator wears three-dimensional image glasses to enjoy a stereoscopic image.

[0003]

However, in the conventional simulation apparatus, it was not possible to enjoy the simulated experience because the image could not be viewed three-dimensionally. Also, although wearing the glasses for three-dimensional images allows a stereoscopic view, it is complicated for the spectators to wear the glasses, and for the entertainer side, management and storage of the glasses requires a lot of labor and cost. Was needed. Further, in the conventional simulation apparatus, it is general that the image does not change depending on the intention of the audience, but the screen changes unilaterally in a predetermined pattern.

The present invention has been made to solve the above problems, and it is an object of the present invention to obtain an image-use simulation apparatus in which a pattern can be freely developed according to the intention of an audience and a three-dimensional image can be simulated. To aim.

[0005]

In order to achieve the above object, the present invention provides a first video screen installed in front of a spectator's seat and a half screen installed in front of the first video screen. Mirror and first for this half mirror
Second video screen installed in a position approximately symmetrical to the video screen of No. 3, a small camera that can move on the imitated diorama, a control stick that can control this small camera in three dimensions, and this small A first projector for projecting an image captured by a camera onto a first image screen, a second projector for projecting an image different from the image from the first projector onto a second image screen, and a small size And a computer that controls the output of an image from the second projector when the camera reaches a predetermined position, and the image projected on the second image screen is placed in front of the first image screen by a half mirror. The feature is that the image is formed.

[0006]

In the above, the live image of the diorama is projected straight on the first video screen installed in front of the spectator seat by the first projector, and the second projector is displayed on the second video screen. Another image is projected by. Since the second video screen is installed at a position substantially symmetrical to the first video screen with respect to the half mirror, the virtual image of the video displayed on the second video screen is converted by the half mirror into the first video screen. Is imaged in front of.

Therefore, the spectator looks directly at the image projected on the first image screen through the half mirror,
Since the virtual image of the second video screen appears superimposed on this video, this virtual image looks stereoscopic on the first video screen. Moreover, the image of the diorama is taken by a small camera moving on it,
The small camera can be freely controlled by the spectator by operating the control stick.

EXAMPLE An example of the present invention will be described below by taking a seabed exploration simulation as an example. First of all, the general ecology and habits of aquatic organisms can be seen in the aquarium where they are kept and displayed, but the organisms living in the deep sea cannot be easily seen. In recent years, diving research ship "Shinkai 65"
Although the appearance of deep-sea creatures is being clarified by the development of "00", it is not possible to breed and display creatures that inhabit the seabed at 600 atm in an aquarium. Therefore, based on this information, the ecology and habits of creatures that cannot be bred in aquariums such as the deep sea are reproduced by using the simulation image technology using SFX to reproduce the state of the deep sea and enable a simulated experience. Is.

FIG. 1 shows a schematic configuration of a video-based simulation apparatus according to the present invention. In the figure, the front row of the spectator seats 24 formed in a room such as a theater hall is a cockpit equipped with a control stick 28, and one of the spectators sits in this cockpit to perform deep sea exploration maneuvers. It can be carried out. The control stick 28 can be controlled in the front-rear direction, the left-right direction, the up-down direction, and the rotating direction, and its operation signal is sent to the small camera 26 (see FIG. 2).

Then, the first projector 18 projects an image of the diorama (model modeled on the view of the seabed) 22 on the first rear screen 14 in front of the spectator seats 24, and the second image is displayed. An image of a marine snow, a deep-sea fish, a sea monster (large octopus), etc. previously taken by the projector 20 is projected on the second rear screen 16 via the surface mirror 12. The second rear screen 16 is installed in a position substantially symmetrical with respect to the half mirror 10, and the image on the second rear screen 16 is transmitted through the half mirror 10 to the first rear screen 16.
An image is formed approximately 10 cm before the rear screen 14 of FIG.

By doing so, the spectator can directly see the seabed scenery (real image) projected on the first rear screen 14 through the half mirror 10, and
The image displayed on the second rear screen 16 is displayed as a virtual image by the half mirror 10 in front of the first rear screen 14 by 10 cm (± 3 cm), so that a real image and a virtual image have a sense of perspective. As a result, deep-sea fish and sea monsters (large octopus) will appear three-dimensional in the image of the seabed. It should be noted that, as described above, the virtual image of the second rear screen 16 is changed to the 10th image of the first rear screen 14.
This virtual image can be seen most three-dimensionally by projecting it in front of cm (± 3 cm). Further, the second rear screen 16 and the front surface mirror 12 are installed at positions that cannot be seen from the audience seats.

The diorama 22 is formed under the floor of the spectator seat 24 as shown in FIG. 2 within a frame of 2 m in width and 10 m in depth, assuming a view of the seabed.
It was produced on a scale of 1/0. A small camera 26 that moves on the diorama 22 is installed on the outer frame of the diorama 22 as shown in FIG. 4, and the small camera 26 can move in three-dimensional directions of x, y, and z. Moreover, a sensor (not shown) for detecting the three-dimensional position is provided, and the position information (three-dimensional position) of the small camera 26 at that time is sent to the computer 32. Further, the operation of the small camera 26 is a movement in consideration of a feeling of floating in water, and when the control stick 28 provided in the cockpit is operated, the small camera 26 is operated.
Is able to freely enter the narrow space of the diorama 22 and the image as it is sent to the first projector 18. The image sent to the first projector 18 is directly projected on the first rear screen 14, and at the same time, the second image is displayed on the second rear screen 14.
The image displayed on the rear screen 16 through the half mirror 10 is combined with the image to appear as a pseudo three-dimensional image.

It should be noted that the image from the second projector 20 is not always output, but the content of the image is also small camera 2.
Different ones are output depending on the position of 6. For example, as shown in FIG. 3, virtual three-dimensional coordinates are set in the frame, and the position of the starting point of the small camera 26 is set to 0 (x _0, y _0, z
₀₎ is the video output of "falling rocks" from the second projector 20 Once in the small camera 26 is, for example, a predetermined region A, also Once in area B picture "large octopus" is output Further, when the area C is entered, the image of the "terrace bedrock" is output. The three-dimensional coordinates in such a frame and the range of the areas A, B, and C are stored in the computer 32 in advance.

Next, a seabed exploration simulation assuming a deep sea exploration trip will be described. The name of the deep-sea boat is called "Abyss", and the dive time of this "Abyss" is 7 minutes. Then, when a passenger from the audience sits in this seat as the "captain" in the front-row pilot seat of the spectator's seat, the ship will soon go on an adventure trip to the deep sea with a signal from the companion. The route, depth, position, temperature and oxygen remaining amount are displayed on the screen in the cockpit, and the first rear screen 14 in front of you is displayed.
Shows the bottom of the deep sea.

Every time the monitor TV 30 installed above the spectator's seat gives a voice and an instruction to change the route by the arrow on the monitor screen, the "captain" moves the control stick 28 back and forth, left and right, and moves in the deep sea. When the "Abyss" entered the area A of Fig. 3, for example, suddenly "rockfall" occurred, so avoid it. Also, when entering the area C, a "terrace bedrock" with a narrow passage appeared, so I went through this bedrock, Alternatively, when entering the area B, a "large octopus" appears, so we proceed while defeating it with a laser gun. In this way, all the audience including the "Captain" can enjoy such an adventure as if they were live. In addition, sound is 4ch
Surround stereophonic sound.

Therefore, this deep sea exploration trip can be enjoyed in the same manner as a personal computer game. For example, if some basic courses are set as exploration courses, and the "captain" operates the control stick 28, a deviation from the basic course is displayed by voice and an arrow on the monitor screen, and a trajectory correction is instructed. Then, set rock fall on course A, encounter an octopus on course B, and set terrace-like rocks on course C. When the "Abyss" approaches a wall of a rock or a trench, a signal tone prompts the driver to correct the direction, and in the event of an accident or emergency, the red light blinks and the model course is automatically corrected to a predetermined model course.

Although the deep sea exploration has been described as an example in the present embodiment, it goes without saying that it can be applied to space exploration, jungle exploration and the like.

[0018]

As described above, according to the image-use simulation apparatus of the present invention, the stereoscopic image cannot be viewed without wearing the three-dimensional image glasses, and the image has the predetermined pattern. Unlike the one-sided change of the screen, it is possible to freely develop the pattern according to the will of the audience and enjoy an unknown pseudo experience with a stereoscopic image.
