Description

Three-dimensional alternating projection apparatus in the air {3 Dimensional image changeable projector}

The present invention relates to a three-dimensional alternating projection apparatus in the air, and more particularly to a device that can alternately project the image of the object and the monitor to a single device.

What is a general stereoscopic projection apparatus? It refers to a device that reflects an object to be projected and projects a three-dimensional image in the air by using reflection characteristics of a collimation mirror and a beam splitter, which are explained by the paraxial theory of geometric optics.

In this stereoscopic projection apparatus, as shown in FIG. 1, when the incident light T reaching the center of gravity of the concave mirror C to the center of the reflecting surface 111 of the concave mirror 110 is called an optical axis, the object is parallel to this optical axis. The light R incident on the concave mirror 110 is reflected through the focal point F of the concave mirror 110.

On the contrary, the light S passing through the focal point F and incident on the concave mirror 110 reflects in parallel to the optical axis.

In addition, light T passing through the center C and incident on the concave mirror 110 is reflected through the center C again, and the reflected light R (S) (T) is a point of the air. Meet each other and make an image.

At this time, when the position of the object Ob is located between the center of the reflecting surface 111 and the focus F, the object Ob is formed into a virtual image established at the rear of the reflecting mirror 110, and the focus F and the center of gravity ( When positioned between the C) is formed into an inverted actual image (Ri) enlarged in front of the concave mirror (110).

In addition, when the object (Ob) is located in the area outside the old center (C) is formed into a reduced inverted actual image (Ri) in front of the concave mirror (110).

The three-dimensional projection apparatus as described above has a problem that it is difficult to use industrially for advertisement and exhibition by using the real Ri and the object Ob on the same line in the observer's field of view.

In order to solve such a problem, as shown in FIG. 2, the anti-reflective mirror 120 is installed so that the incident light T reaching the center of the reflecting surface 110 of the concave mirror 110 is refracted by 45 °. The optical axis between the object and the object Ob is maintained at 90 °, and only the real image Ri is projected into the air and used for advertising and exhibition.

However, in the above case, it is difficult to project the image of the monitor 20 and the object 10 to one device in the same space in the air.

That is, the target to be projected should always be located in a certain area in a state that is isolated from the outside, but when the monitor 20 and the object 10 are located at the same position, the image Ri of the projected monitor 20 image overlaps or is shadowed. To prevent the projection of the image and the object 10 of the mutual monitor 20 and the illumination of the object (10) to supply the light required for projecting the object 10, the outline of the monitor 20 itself is exposed to the three-dimensional projection effect There was a problem to halve.

The main object of the present invention is to provide a three-dimensional alternating projection apparatus in the air so that the projection of the image of the monitor and the object can be conveniently conveniently projected in three-dimensional image in the air.

It is another object of the present invention to provide a more convenient and inexpensive three-dimensional alternating projection apparatus in the air by selectively alternating and projecting a three-dimensional image of a monitor image and an object with one device.

Another object of the present invention is to provide a three-dimensional alternating projection apparatus in the air to maximize the advertising and exhibition effects, such that the three-dimensional image of the monitor image and the object can be easily alternately projected.
