Description

Automatic Visualization Method and Apparatus for Heterogeneous Hologram-Like Systems

The present invention relates to a method and apparatus for automatic content visualization between heterogeneous pseudo-hologram systems.

Recently, technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR) for providing users with experiences using immersive, realistic content have been greatly developed. However, in the case of an immersive device such as a head-mounted display (HMD) for visualizing content, there is a limitation in providing only a narrow field of view as well as inconvenience in having to wear it. In addition, when a wearable device is used and a collaborative environment in which multiple users view the same content at once is configured, the system configuration and content creation method become more complicated. As a way to overcome this, the development of a hologram system that provides convenience to users and does not require a separate wearable device is being actively developed in recent years. Hologram is a technique that provides the effect of projecting virtual content into the air based on the interference effect of light, but it currently has limitations in visualizing natural-colored content. There are still difficulties. Therefore, a hologram-like system that visualizes virtual content in the air in life-size is actively used to provide an immersive experience opportunity and to provide a content experience for collaboration. That is, the pseudo-hologram system provides a floating effect that makes virtual content appear to be floating in the air, and has the advantage of providing a realistic experience to large-scale users compared to conventional displays. In this pseudo-hologram system, hardware (H/W) is set according to the characteristics of the installation site in order to provide an effective experience. In addition, according to the properties of the content to be experienced, various types can be configured, from a large single screen (more than 2m) type pseudo-hologram system to a pyramid type system (3 or 4 sides). At this time, for the pseudo hologram system having various types of hardware configuration, various visualization factors such as the number of surfaces on which the object is projected, the angle of the surface, the display size, the location of the content, and the interface location should be considered, and the appropriateness of the inside of the pseudo hologram system should be considered. A virtual object that can be clearly visualized should be placed. However, even if the content is executed to visualize the same virtual object, the content setting is changed in consideration of the visualization elements (virtual camera angle, viewing angle, number, etc.) I have a problem that needs to be done. That is, it is cumbersome to deform and reconfigure content according to the hardware configuration of the pseudo-hologram system.

Accordingly, the technical problem to be solved by the present invention relates to a method and apparatus for automatically visualizing content between heterogeneous similar hologram systems for automatically visualizing the same content between heterogeneous similar hologram systems having various types of hardware.

The method for automatically visualizing content between similar hologram systems comprising one or more reflective mirrors according to the present invention for solving the above technical problem includes the display type of the holographic-like system, the number of reflective mirrors, and height and width information of each reflective mirror The method includes the steps of receiving the pseudo-hologram system property information, converting content according to the pseudo-hologram system property information, and outputting and projecting the converted content to the pseudo-hologram system.

The viewing angle and position of a virtual camera corresponding to each of the one or more reflective mirrors may be determined based on the pseudo-hologram system property information, and the content may be converted to be projected on the corresponding reflective mirror.

The similar hologram system property information may further include position adjustment information for adjusting a position at which the content is projected on the reflective mirror.

The position adjustment information may be determined as a value input by a user for content position adjustment on a reflective mirror in a state in which predetermined primitive data is projected onto the one or more reflective mirrors.

An apparatus for automatic content visualization between similar hologram systems comprising one or more reflective mirrors according to the present invention for solving the above technical problem, the display type of the holographic similar system, the number of reflective mirrors, and height and width information of each reflective mirror. It includes an input unit for receiving the pseudo-hologram system property information, a converting unit for converting content according to the similar hologram system property information, and an output unit for outputting the converted content to the pseudo-hologram system and projecting it.

According to the present invention, even when the same content is executed in heterogeneous similar hologram systems, there is an advantage in that content can be naturally visualized between heterogeneous similar hologram systems. Therefore, there is an advantage in that the content creator only needs to produce the content without considering the configuration of the pseudo-hologram system.

Then, with reference to the accompanying drawings, the embodiments of the present invention will be described in detail so that those of ordinary skill in the art can easily carry out the present invention.

1 shows an example of the configuration of a projection-type pseudo-hologram system using a large single screen.

Referring to FIG. 1 , the person 4 located on the actual stage and the virtual object 3 to be projected by the pseudo-hologram system are not actually located in the same space, but the light projected from the beam projector 1 is reflected on the translucent screen 2 The user 5 feels that the projected object and the real object are actually together.

2 illustrates a three-sided pyramid-like hologram system, and FIG. 3 illustrates a four-sided pyramid-like hologram system.

The hardware configuration of the three-sided pyramid-like hologram system illustrated in FIG. 2 is composed of a monitor for displaying content, and three translucent screens for visualizing the front/left/right side. And the four-sided pyramid-like hologram system illustrated in FIG. 3 has a display form of four sides. The four-sided pyramid-like hologram system can be said to include the back side of the three-sided system.

In such a pyramid-like hologram system, after placing the monitor on which the real virtual object is projected on the top or the bottom, the virtual object coming out of the monitor is projected on the inclined semi-transparent screen so that the virtual object is reflected on the semi-transparent screen, It should be placed on the monitor according to the number and position. Through this, the user observing the pyramid-like hologram system can feel the spatial sense of the virtual object from various directions by observing the virtual object projected on the translucent screen. In this case, the content creator should set the location of the virtual object in consideration of the size, angle, and number of sides of the translucent screen, and then create the content.

4 shows an example in which a virtual object expressed on a physical display is visualized in a three-sided pseudo-hologram system.

As already mentioned, the pseudo-hologram system can be configured in various forms according to the characteristics of the place to be installed and the purpose of use. Differences may occur in various factors, such as the difference in the number of projection surfaces, the angle of the display (or monitor), the arrangement position of the visualization content for image expression, the size and direction of the translucent display and the image reproduction display, like the single projection method and the pyramid method. have. In order to optimize the contents according to these various types of hardware configuration characteristics, it is necessary to correct the visualization components of various pseudo-hologram systems. For example, when applying the same input content (or video) to different types of similar hologram systems, it is necessary to understand the hardware characteristics of the similar hologram system and consider how many sides the corresponding content should be divided into, and target similarity The correlation between the hologram system and the input content should be defined in advance and corrected based on the parameters. That is, the inconvenience of having to redesign and readjust the contents separately according to the characteristics of the pseudo-hologram system occurs.

In addition, position information (Position X, Position Y) information for fine adjustment of content positions in each of the front reflective mirror 10F, the left reflective mirror 10L, and the right reflective mirror 10R may be received. Position X is a value for displaying content by adjusting the position left and right from the center of each reflective mirror, and Position Y is a value for displaying by adjusting the height from the base of each reflective mirror up and down.

In a state in which primitive data having a predetermined pattern (eg, triangle, etc.) is output through the output unit 550 and projected on the reflective mirror, the user watches it and finely adjusts the position of the content on the reflective mirror, and the corresponding Position X and Position Y may be input as a position adjustment value.

The lower part of FIG. 6 exemplifies the attribute information input screen of the four-sided pyramid-like hologram system. In the lower part of FIG. 6 , a column for inputting height, width, and fine adjustment position information for the rear reflection mirror (Back) is additionally displayed.

Specifically, the conversion unit 530 may determine the viewing angle and position of a virtual camera corresponding to each of one or more reflective mirrors, and may convert the content to be projected on the corresponding reflective mirror.

The left side in FIG. 7 shows each of the three reflection mirrors 10F, 10L, and 10R of the three-sided pyramid-like hologram system. In general, the reflective mirror of the pseudo hologram system has a symmetrical structure in most cases as illustrated in FIG. 7 .

Meanwhile, the right side in FIG. 7 illustrates a screen displayed on the output unit 550 . The output unit 550 may be implemented as a display module such as an LED module, an LCD module, or an OLED module of a smartphone.

In the output unit 550, the screen is divided into a front area 20F, a left area 20L, and a right area 20R corresponding to each of the three reflection mirrors (Front, Left, Right), and corresponding to each divided area. The converted content may be output.

The content output from the output unit 550 to each of the regions 20F, 20L, and 20R may be projected onto the corresponding reflective mirrors 10F, 10L, and 10R to visualize the virtual object.

On the other hand, if the pseudo-hologram system is a four-sided pyramid, the screen displayed on the output unit 550 may be divided into four regions, and content to be projected on the four reflective mirrors may be output in each of the divided regions.
