Hologram statue display device and method {Apparatus and method for displaying hologram of statue}

The present invention relates to an apparatus and method for displaying a holographic image. More specifically, the present invention relates to an apparatus and method for displaying a holographic statue embodying the statue in a holographic image.

A hologram is a three-dimensional image that looks three-dimensionally like the real thing, and is made using the principle of holography. The principle of holography is to split the beam from the laser into two, one light shining directly on the screen, and the other light shining on the object we want to see. In this case, the light directly shining on the screen is called a reference beam, and the light shining on the object is called an object beam. Since object light is light reflected from each surface of an object, the phase difference (distance from the surface of the object to the screen) varies depending on the surface of the object. In this case, the unmodified reference light interferes with the object light, and the hologram is displayed on the screen by the interference fringe.

In the past, holographic images were used to display articles in showcases and expos. The short channel method was used to display this holographic image. However, the short channel method is a method of being displayed on a flat surface, so that a three-dimensional effect of the hologram image is reduced. A four channel method has been proposed as a way to compensate for this drawback. However, the four-channel method has a problem in that the structure of a system for implementing a holographic image is complicated, such as a projector is provided for each channel, and the manufacturing cost increases. In addition, when using a four-channel method to view the hologram image from all directions, it is difficult to express a fine three-dimensional effect.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are assigned to the same components as much as possible even if displayed on different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the following will describe a preferred embodiment of the present invention, but the technical idea of the present invention is not limited thereto and may be variously modified and modified by those skilled in the art.

1 is a block diagram schematically illustrating a holographic in-phase display device according to a preferred embodiment of the present invention. FIG. 2 is a block diagram schematically illustrating a configuration added to the holographic in-phase display device of FIG. 1. The following description refers to FIGS. 1 and 2.

According to FIG. 1, the holographic in-phase display device 100 includes a stereoscopic image generating unit 110, an image output unit 120, a holographic image display unit 130, a holographic image display control unit 140, a power supply unit 150, and a main control word. The unit 160 is included.

Since holograms are commercially available, many images or images may be expressed as holograms. However, such hologram images generally do not require detailed three-dimensional or color sensations unlike art works such as statues and bust. The holographic frostbite display apparatus 100 according to the present embodiment is a device that implements a frostbite or a bust as a holographic image. In particular, the holographic frostbite display apparatus 100 displays a holographic frostbite by using a three-channel method using an opaque surface (that is, a wall located behind). Device. The holographic in-phase display device 100 according to the present embodiment has the following differences when compared to the four-sided method. First, there are differences in size. The apparatus 100 can be reduced in size by using a glass method for bonding glass together without a frame for supporting the glass. Second, there is a difference in how images are put on semi-reflective glass. By arranging the images on the monitor by using the wall surface in the manner of forming the image, the image can be made clear by the wall surface.

The stereoscopic image generator 110 performs a function of generating a stereoscopic image of the stereoscopic sculpture. The following three methods are used by the stereoscopic image generator 110 to generate a stereoscopic image. First, a three-dimensional object is scanned three-dimensionally to generate a three-dimensional image. Second, a three-dimensional object is planarly scanned in at least two directions to generate a stereoscopic image. In this case, by obtaining the feature points of the three-dimensional sculpture in various directions can improve the three-dimensional appearance of the three-dimensional sculpture. Third, a stereoscopic image is generated using an authoring tool. In the present embodiment, the stereoscopic image generator 110 scans the in-phase with a stereoscopic sculpture.

The stereoscopic image generator 110 may generate a stereoscopic image by performing a 3D scan on a stereoscopic sculpture (eg, a statue, a bust, etc.). The stereoscopic image generator 110 may generate a stereoscopic image (3D image) by combining scanned images (2D image) scanned in various directions. In addition, it is also possible to generate a stereoscopic image using a program that generates a 3D image without scanning a stereoscopic sculpture, that is, a 3D authoring tool (eg, 3D MAX, zbrush, etc.).

When the stereoscopic image generator 110 generates a stereoscopic image by performing 3D scanning, the following procedure may be performed. First, a 3D scan is performed on a three-dimensional sculpture to generate an initial three-dimensional image of the three-dimensional sculpture. Then, the first stereoscopic image is corrected using a 3D authoring tool. Then, 2D images on each side are obtained from the first stereoscopic image. In this case, the acquired 2D image may include a front image, a rear image, a left image, a right image, a bottom image, and a top image. Thereafter, a mapping source for mapping a stereoscopic image is extracted through a mapping operation on each 2D image. In this embodiment, at this stage, the figure of the person's face can be worked out as an unfolded picture. Subsequently, the final stereoscopic image is generated by reflecting the mapping source in the initial stereoscopic image. This step may proceed to the process of completing the shape of the final figure statue by applying the mapping source of the developed view to the scanned figure.

Meanwhile, the stereoscopic image generator 110 may generate a stereoscopic image in the form of a video or an animated image in cooperation with the holographic image display controller 150. This step can proceed to the process of combining the animation with the video using a video editing program with a completed portrait.

The image output unit 120 performs a function of outputting a stereoscopic image as a holographic image at a predetermined output point.

The hologram image display unit 130 includes display windows on which the hologram image is displayed. At this time, at least one of the display windows is formed as a wall attachment window attached to the wall or formed as an opaque window. All the windows except the wall attachment window or the opaque window may be formed as transparent windows. The wall attachment window or opaque window may be formed of at least one material of wood, stone, and steel, and the other windows except the wall attachment window or opaque window may be formed of semi-reflective glass.

The holographic image display control unit 140 controls the image output unit 120 and the holographic image display unit 130, and has a function of placing an output point in the space between the display windows in consideration of the position of the wall attachment window or the opaque window. To perform.

The holographic image display controller 140 manipulates the holographic image such that the shape or position of the holographic image is changed at predetermined time intervals. The hologram image at this time may be implemented in a video form or an animation form. In this embodiment, since a non-material hologram statue made of light is used to break away from a material statue that was previously made of marble or bronze, it is not fixed in one direction and moves to the left or right through an animation motion or a special effect is used to move the statue. It can move and give a sense of vitality and rhythm.

The power supply unit 150 supplies power to each component of the hologram in-phase display device 100.

The main controller 160 controls the overall operation of each component constituting the holographic in-phase display device 100.

The holographic in-phase display apparatus 100 may further include a stereoscopic image divider 170 as illustrated in FIG. 2 (a). The stereoscopic image divider 170 divides a stereoscopic image, and in this embodiment, the stereoscopic image is divided into a number corresponding to the number of display windows. In this case, the holographic image display control unit 140 may control to display the divided image according to the image segmentation for each display window. For example, the stereoscopic image divider 170 divides the stereoscopic image into a front image and at least one side image, and divides the side image into a left image and a right image. That is, the stereoscopic image divider 170 divides the stereoscopic image into three images.

Originally, all great statues do not have their backside visible. In particular, the case is installed indoors. Thus, in the present embodiment, in order to use the wall of the building where the statue is installed as an opaque surface to finish using wood, stone, steel, etc. and to produce the holographic statue projected to the remaining three sides using the reflective glass. The statue is shown on the backside of the wall, and the back side is not seen naturally. In addition, if the background finish behind the hologram statue on the wall, the three-dimensional effect is excellent and the sharpness and visibility of the statue can be improved. In this embodiment, in consideration of this point, the data of the in-phase are divided into three and displayed on the monitor.

In the present embodiment, since the hologram image is displayed using a monitor that outputs a stereoscopic image, the stereoscopic image may not be divided. However, in the present embodiment, it is also possible to display a hologram image by using a projector that generates a light source. In this case, the stereoscopic image is preferably divided according to the number of light sources.

The hologram in-phase display device 100 may further include an image size adjusting unit 180 as shown in FIG. 2 (b). The image size adjusting unit 190 adjusts the size of the stereoscopic image based on the actual size of the stereoscopic sculpture.

FIG. 3 is an exemplary view of the image output unit 130 and the holographic image display unit 140 shown in FIG. 1, and is a perspective view of a configuration including the anti-reflective glass assembly 200 and the monitor 230. In FIG. 3, the anti-reflective glass assembly 200 and the monitor 230 correspond to the holographic image display unit 140 and the image output unit 130, respectively.

In the present embodiment, as shown in FIG. 3, the hologram image 220 is output upward through the monitor 230, and the front and left sides of the assembly 200 are based on the point at which the hologram image 220 is output. By placing the semi-reflective glass 210 on three sides, such as the right side, it becomes possible to enjoy the hologram image 220 from the outside. However, the display of the hologram image is not limited to this configuration. For example, it is also possible to display a hologram image using a projector, a screen, a photosensitive film, or the like. On the other hand, the semi-reflective glass 210 is located in three surfaces are formed in the reverse pyramid form.

The wall attachment part 260 attached to the wall surface is formed on the rear surface of the assembly 200 which is not formed of the semi-reflective glass 210. The wall attachment part 260 may itself be formed as an opaque surface, but may be formed as a transparent surface. The reason is that even if it is formed as a transparent surface, since it is a surface attached to the wall surface, a substantially opaque surface effect can be obtained by the wall surface. In this embodiment, the wall attachment portion 260 may be formed, that is, the visibility and three-dimensionality of the holographic statue may be emphasized by setting the environment wall of the building behind the three-sided semi-reflective glass. Using existing walls adds a sense of unity with the building and naturally hides the back of statues that are not open to the public. On the other hand, when the wall attachment portion 260 is formed as an opaque surface, the wall attachment portion 260 does not necessarily need to be attached to the wall surface.

The image processing apparatus 300 is a configuration in which the stereoscopic image generator 110, the stereoscopic image divider 120, the holographic image display controller 150, and the like of FIG. 1 are combined. In the present exemplary embodiment, the image processing apparatus 300 may be provided under the monitor 230, but may be separately provided from the monitor 230.

In the present embodiment, the holographic image output point 240 is a point where the equal dividing lines for equally dividing the semi-reflective glass 210 positioned on each side in the vertical direction are referred to as the hologram image output point 240, based on the point 240. The hologram image 220 is displayed on the monitor 230. If the hologram image 220 is displayed at a point other than the hologram image output point 240, the hologram image 220 may be distorted or a part of the hologram image 220 may not be properly displayed. Thus, in the present embodiment, the inclination value C of each side reflection glass 210 with respect to the monitor 230 is 30 ° to 60 ° (preferably 45 °) and the length D of each side reflection glass 210. When the bottom length (B) of the semi-reflective glass assembly 200 is 150 cm to 200 cm and 50 cm to 60 cm, respectively, the distance between the hologram image output point 240 and the wall attachment part 260 is preferably 5 cm to 8 cm. .

5 is a reference diagram for describing an image segmentation function performed by the stereoscopic image segmentation unit 120 of FIG. 1. In particular, FIG. 5 is a plan view illustrating a configuration including the screen 210 and the monitor 230 of FIG. 3.

The stereoscopic image divider 120 divides the stereoscopic image of the stereoscopic sculpture into one front image 221 and two side images 222. As shown in FIG. 5, the screen 210 is composed of a transparent surface in three directions and an opaque surface in one direction. The opaque surface corresponds to the wall attachment portion 260 attached to the wall. The front image 221 is displayed on the transparent surface positioned in the center of the three transparent surfaces, and each side image 222 is displayed on the transparent surfaces positioned on both sides. In this embodiment, in relation to the division of the three-sided image (3D SCAN), in order to effectively produce the three-dimensional effect of the commemorative statue (the general figure statue does not show the back), it is constructed so that the three sides are viewed from all three sides. do. Meanwhile, in the present embodiment, three monitors and projectors may be provided to display the divided images on each side, and may be replaced according to the image size.

The following description refers to FIG. 8.

First, the stereoscopic image generator 110 generates a stereoscopic image of the stereoscopic sculpture based on the scanned images of the stereoscopic sculpture (stereoscopic image generation step S10).

After the stereoscopic image generation step S10, the stereoscopic image splitter 170 divides the generated stereoscopic image into a front image and at least one side image (stereoscopic image segmentation step S20). In this case, the stereoscopic image splitter 170 may divide the left image and the right image from the stereoscopic image into the side image.

After the stereoscopic image segmentation step (S20), the holographic image display control unit 140 between the image output unit 120 for outputting each segmented image according to the stereoscopic image segmentation and the holographic image display unit 130 for holographic display of the output image. In consideration of the positional relationship, one segmented image is holographically displayed on each transparent surface except for at least one opaque surface (hologram image display step S30). In the holographic image display step S30, the holographic display may be performed in the form of animation by changing the holographic image displayed at a predetermined time.

Meanwhile, before the stereoscopic image generating step S10, the sculpture scanning step S5 may be performed. Sculpture scan step (S5) means that the three-dimensional scan the three-dimensional sculpture by the sculpture scanning unit. The sculpture scanning unit may scan a three-dimensional sculpture in at least two directions to perform a three-dimensional scan by three-dimensional scanning. The sculpture scanning unit may three-dimensionally scan the statue in three-dimensional sculpture.

On the other hand, when displaying the holographic in-phase can further perform the image size adjustment step. The image size adjusting step refers to a step in which the image size adjusting unit 180 adjusts the size of the scanned image or the divided image based on the actual size of the three-dimensional sculpture. When the scanned image is scaled, the image scaling step is performed before the stereoscopic image generation step S10. On the other hand, when the size of the divided image is adjusted, the image size adjusting step S25 is performed between the stereoscopic image segmentation step S20 and the holographic image display step S30.
