Referring to FIG. 1, the user terminal 100 and the server 200 are connected to each other through a network. The user terminal 100 and the server 200 may transmit and receive various data and / or information. Networks include wired or wireless networks. The scale, topology, and communication method of a network may be provided in various variations according to embodiments.

The user terminal 100 represents a computer system used by a user. For example, the user terminal 100 may be provided as a mobile computer system such as a smart phone, a tablet, or a personal digital assistant (PDA). Alternatively, the user terminal 100 may be provided as a fixed computer system such as a laptop or desktop. The user terminal 100 is not limited to the above-described examples, and may be connected to the server 200 through a network and may be provided as an arbitrary computer system having a display. The user terminal 100 may store and execute an application for interworking with the server 200. The application may include various commands, data and information.

The server 200 provides a virtual exhibition space. The server 200 provides an exhibition image to the user terminal 100 according to a request from the user terminal 100. The exhibition image is provided as a three-dimensional image as described below. In some embodiments, the exhibit image is drawn by perspective perspective. In addition, the exhibition image is drawn to have a predetermined view point and a predetermined number of vanishing points. Detailed description of the perspective perspective is omitted because it may obscure the subject matter of the present invention.

As described below, a snapshot image is used to create a three-dimensional display image. The snapshot image is an image in which one or more artwork images are overlapped and arranged on a flat image on the wall. Through the 2.5-dimensionalization of such a planar snapshot image, a three-dimensional display image can be generated.

Meanwhile, as illustrated in FIG. 1, a plurality of user terminals 100 may be connected to the server 200. One user terminal 100 may be used by the first user, and the other user terminal 100 may be used by the second user. The first user registers a work image for exhibition as described below as an administrator (eg, an artist, curator, or collector) of the virtual exhibition space. As a spectator of the virtual exhibition space, the second user views and views the exhibition image and the work image as described later. It will be clearly understood that one user can be classified as the first user and the second user at the same time.

2 is a flowchart schematically illustrating a process of setting a spatial image of a method for providing a virtual exhibition space according to an embodiment of the present invention.

Referring to FIG. 2, in step S310, the server 200 prepares a spatial image in which the exhibition space is three-dimensionally depicted. Spatial images define a virtual (ie non-existent) exhibition space. The spatial image may be pre-stored in the user terminal 100 by being embedded in the application.

3 is a diagram schematically showing a spatial image in which the exhibition space is three-dimensionally depicted.

As shown in Figure 3, in some embodiments, the spatial image 10 is drawn by perspective perspective. In addition, the spatial image 10 may have a form in which a plurality of one-point perspective views or two-point perspective views are integrated. That is, the spatial image 10 is drawn to have a plurality of viewpoints and one or more vanishing points corresponding to each viewpoint.

The exhibition space in the spatial image 10 includes a plurality of surfaces. Here, the surface includes a plurality of wall surfaces (A), a ceiling surface (B), and a floor surface (C). In some embodiments, the ceiling surface B may be depicted in an open form with the ceiling omitted. As will be described later, in general, the wall (A) will be used for the placement and display of the work image, but in some embodiments, the ceiling (B) or floor (C) is also used for the placement and display of the work image. Can be used. The number of wall surfaces (A) can be variously increased or decreased depending on the embodiment. The arrangement form of the wall surface A may also be variously modified according to embodiments.

Meanwhile, although not clearly illustrated in FIG. 3, in some embodiments, light, contrast, color, and shadow may be further depicted in the spatial image 10. In addition, objects (for interior design) other than the work may be further depicted in the spatial image 10.

In some embodiments, the proportion of each wall surface A of the exhibition space defined by the spatial image 10 may be fixed to be unified. That is, the horizontal to vertical ratios of the plurality of wall surfaces A may be fixed to the same value. The ratio can be determined in advance. On the other hand, the sizes of the plurality of wall surfaces A are not fixed uniformly. For example, the ratio of the plurality of wall surfaces A may be fixed to the aspect ratio of a typical mobile computer system at 16: 9. Thus, as described later, when a planarly depicted wall image or snapshot image is provided to a user, the image may be displayed full on the entire area of the screen of the user terminal 100. Meanwhile, the proportions of the plurality of wall surfaces 10 are not limited to the above example.

4 is a diagram schematically showing that a spatial image is provided to a user through a user terminal. 4 illustrates a case where the user terminal 100 is a smartphone.

As illustrated in FIG. 4, since the spatial image 10 has a shape extended in a horizontal direction, an area that can be displayed on the screen of the user terminal 100 is limited. Depending on the position of the user's gaze in the virtual exhibition space, some wall surfaces (eg, 13) are displayed on the screen of the user terminal 100, and other wall surfaces (eg, 11, 15) are displayed on the user terminal 100 ) Is not displayed on the screen. As the position of the user's gaze moves, the area of the spatial image 10 displayed on the screen of the user terminal 100 may be changed. The position of the user's gaze may move intermittently or continuously. The operation for moving the position of the user's gaze may be performed in various ways.

On the other hand, the display image 50 to be described later, like the spatial image 10, is limited to an area that can be displayed on the screen of the user terminal 100.

In some embodiments, the spatial image 10 may have an elongated shape in the vertical direction.

Referring again to FIG. 2, in step S320, the server 200 analyzes a plurality of wall surfaces on the spatial image 10. As a result of the analysis of the spatial image 10, the server 200 acquires the scales of the plurality of wall surfaces of the spatial image 10, and acquires the slope values of the plurality of wall surfaces. Here, the obtained scale and tilt values of each wall surface are used for adjustment of a snapshot image described later.

5 to 6 are views schematically illustrating the analysis of the scale and slope values of a plurality of wall surfaces. 5 to 6 exemplify a case in which the scale and the slope value of a specific wall surface 13 are analyzed.

Referring to FIG. 5, the scale means the ratio of the wall surface to the exhibition space. That is, the scale means the ratio (S1: S2) of the area (S1) of each wall surface 13 to the total area (S2) of the exhibition space depicted on the spatial image (10).

Referring to FIG. 6, if the user's viewpoint is assumed to be located in front of each wall surface 13 in the spatial image 10, the slope value is inclined clockwise or counterclockwise on the plane. Degree. The server 200 acquires coordinates of four corners of the plurality of wall surfaces 13 of the spatial image 10, a fixed ratio (eg, 16: 9) of the plurality of wall surfaces 13 and a plurality of wall surfaces 13 ), It is possible to obtain the slope values of the plurality of wall surfaces 130 based on the four corner coordinates.

6 is a view showing a specific wall surface 13 on a plane (ie, a top view) in a virtual exhibition space. The server 200 acquires an angle of θ1 or θ2 as shown in FIG. 6 as a slope value.

7 is a flowchart schematically illustrating a process of registering a work in a method for providing a virtual exhibition space according to an embodiment of the present invention.

Referring to FIG. 7, in step S410, the user terminal 100 displays the spatial image 10 on which the exhibition space is three-dimensionally depicted on the screen. The spatial image 10 may be provided for each exhibition space. The first user may select a specific exhibition space among a plurality of exhibition spaces, and the user terminal 100 may display a spatial image 10 on which the selected exhibition space is depicted on the screen.

Subsequently, in step S420, the user terminal 100 receives a selection of the first user for a specific wall surface among the plurality of wall surfaces on the spatial image 10. Subsequently, in step S430, the user terminal 100 displays a wall image of the specific wall on which the specific wall is depicted on the screen. Subsequently, the user terminal 100 receives a command of the first user to overlap and place one or more pieces of work images in a specific size at a specific location on the wall image. Then, the user terminal 100 obtains the arrangement information of one or more work images including the specific location and specific size.

8 to 9 are views schematically illustrating the arrangement of a work image on a wall image of a specific wall surface. 8 to 9 illustrate the case where the user terminal 100 is a smartphone.

Referring to FIG. 8, the user terminal 100 displays the spatial image 10 on a screen, and the first user can select a specific wall surface 13 among a plurality of wall surfaces on the spatial image 10 by a touch method or the like. have.

Referring to FIG. 9, the user terminal 100 displays a wall image 23 on which a specific wall 13 is depicted on the screen. The wall image 23 depicts the wall surface in which the work is not arranged. In some embodiments, the wall image 23 is displayed on the entire area of the screen of the user terminal 100. The first user may select one or more work images 31 and 32 stored in the user terminal 200 or a cloud storage, and overlap and arrange them on the wall image 23. The first user may adjust and arrange one or more pieces of work images 31 and 32 to a specific size at a specific location. Although two pieces of work images 31 and 32 are shown in FIG. 9, one or more pieces of work images may be arranged. When the user terminal 100 is a smart phone, a command of the first user for arranging one or more work images 31 and 32 may be provided by a touch or a specific gesture. Also, the first user's command may include one or more of movement, rotation, enlargement, and reduction of one or more work images 31 and 32.

In some embodiments, the location of the work image 31 may be defined by the coordinates of one or more corners P1 of the work image 31 or the center P2. Here, the coordinates are defined in relation to a specific wall surface on which the work image 31 is placed (ie, a coordinate system of a specific wall surface). For example, the coordinates of a certain corner of a specific wall surface are defined as (0,0). In some embodiments, the size of the work image 31 may be defined as a ratio (wd1: wd2) of the width wd1 of each work image 31 compared to the total width wd2 of a specific wall surface. However, the method of defining the position and size of the work image 31 is not limited thereto.

Subsequently, in step S450, the user terminal 100 generates a snapshot image of a specific wall surface in which one or more work images are overlapped and arranged on the wall image 23. That is, a snapshot image is generated as if a wall image in which one or more artwork images are arranged is captured or captured. The snapshot image is used to reduce a loading time experienced by a user by temporarily (or temporarily) displaying a work image or the like on the screen before receiving and loading a work image or the like as described later. In some embodiments, the quality of the snapshot image is predetermined and may be lower than the quality of the artwork image. This is to reduce the size of the data and reduce the loading time. In some embodiments, a snapshot image may be created only on the wall where the work is placed.

Subsequently, in step S460, the user terminal 100 transmits identification information of a specific wall surface, arrangement information of one or more work images, a snapshot image 43, and one or more work images 31 and 32 to the server 200. .

10 is a flowchart schematically showing a process of viewing a work of a method for providing a virtual exhibition space according to an embodiment of the present invention.

Referring to FIG. 10, in step S510, the user terminal 100 prepares a spatial image 10 in which the exhibition space is three-dimensionally depicted. The spatial image 10 may be provided for each exhibition space. The second user can select a specific exhibition space among a plurality of exhibition spaces, and the user terminal 100 can prepare a spatial image 10 in which the selected exhibition space is depicted. The spatial image 10 may be embedded in an application and pre-stored in the user terminal 100.

Subsequently, in step S520, the user terminal 100, the identification information of a specific wall among the plurality of walls on the spatial image 10 and the specific wall are depicted in a plane, and one or more pieces are arranged in a specific size at a specific location on the specific wall. The depicted snapshot image of the specific wall surface is received from the server 200. That is, the user terminal 100 receives a snapshot image of a specific wall surface generated in step S450. In some embodiments, the user terminal 100 receives a snapshot image only on the wall where the work image is placed in the process of registering the work. Also, the user terminal 100 receives arrangement information of one or more work images and one or more work images 31 and 32 from the server 200.

Subsequently, in step S530, the user terminal 100 uses the snapshot image and the scale and slope values of the specific wall surface on the spatial image 10 corresponding to the identification information of the specific wall surface to determine the snapshot image of the spatial image 10. Adjusted to follow the three-dimensional element, and placed on an overlapping surface on a specific wall on the spatial image 10 to generate an exhibition image. Subsequently, in step S540, the user terminal 100 displays the exhibition image on the screen. Here, "to follow the three-dimensional element" means to adjust by a perspective perspective to have the same viewpoint and vanishing point as a specific wall surface on the spatial image 10, unlike the planar depiction of the original. The three-dimensional element may include, for example, a viewpoint or a vanishing point.

11 to 12 are views schematically illustrating the creation of an exhibition image by overlapping and disposing a snapshot image on a spatial image.

Referring to FIG. 11, the user terminal 100 prepares a spatial image 10. In FIG. 11, although the user terminal 100 is shown to display the spatial image 10 on the screen, this is to help the understanding of the present invention through the contrast of the spatial image 10 and the exhibition image 50, and the user The terminal 100 does not actually display the spatial image 10 on the screen. Since the spatial image 10 merely depicts an exhibition space, a work image is not arranged on a specific wall 13 of the spatial image 10. The user terminal 100 receives the snapshot image 43 generated in the above-described work registration process from the server 200, not the work image. Then, the user terminal 100 adjusts the snapshot image 43 to follow the three-dimensional elements of the spatial image 10, and overlaps and arranges on the specific wall surface 13 on the spatial image 10 to display the exhibition image 50. ). The exhibition image 50 is generated in the form of a combination of the spatial image 10 and the snapshot image 43. In particular, when a plurality of work images are arranged on one wall surface, only one snapshot image of the wall surface on which the plurality of work images are arranged is received from the server 200. Then, the snapshot image is used to generate an exhibition image.

Subsequently, in step S550, the user terminal 100 receives a second user's selection for a specific wall among the plurality of wall surfaces on the exhibition image 50. Subsequently, in step S560, the user terminal 100 displays a snapshot image of the specific wall surface in which a specific wall surface is depicted in a plane and one or more pieces are arranged in a specific size at a specific location on the specific wall surface. Subsequently, in step S570, the user terminal 100 receives a second user's selection for a specific work among one or more works on the snapshot image.

Subsequently, in step S580, the user terminal 100 displays the work image of the specific work on the screen using the arrangement information of the work image (for example, 31) of the specific work. The arrangement information of the work image may be used to determine a selection area of a specific work. Also, the arrangement information of the work image may be used to provide effects such as animation in the process of displaying the work image on the screen. The user can also select and enlarge the work image to view it. Accordingly, the second user can view each work image in detail in addition to the exhibition image 50 and the snapshot image.

14 is a block diagram schematically illustrating an environment in which 3D VR data corresponding to an exhibition image is generated and provided.

Referring to FIG. 14, the user terminal 100 generates 3D VR data 60 using the exhibition image 50. Then, the user terminal 100 provides the 3D VR data 60 to the VR terminal 600, so that the user can experience a 3D virtual reality space. In some embodiments, the 3D VR data 60 may be post-processed in a format, structure, or form suitable for the VR terminal 600. In FIG. 14, for explanation, the VR terminal 600 is shown as a head mounted display (HMD) type, but is not limited thereto, and the VR terminal 600 may be provided in various types well known in the art. have.

Meanwhile, the user terminal 100 may function as a VR terminal independently or in combination with a headset. In this case, the user terminal 100 may directly provide the 3D VR data 60 to the user.

In addition, when the exhibition image 50 generated by the user terminal 100 is transmitted to the server 200, the server 200 may generate the 3D VR data 60 using the exhibition image 50. have. In this case, the user terminal 100 may receive the 3D VR data 60 from the server 200 and provide the 3D VR data 60 to the VR terminal 600 or directly to the user.

15 is a flowchart schematically illustrating a method for generating 3D VR data according to an embodiment of the present invention.

15, in step S710, the user terminal 100 analyzes the exhibition image 50. The user terminal 100 analyzes a plurality of wall surfaces on the exhibition image 50 to obtain three-dimensional coordinates on the exhibition space of the plurality of wall surfaces of the exhibition image 50.

FIG. 16 is a diagram schematically illustrating to obtain a 3D coordinate by analyzing an exhibition image. 16 exemplifies a case in which three-dimensional coordinates on a specific wall surface 53 on the exhibition space are acquired.

Referring to FIG. 16, in a virtual exhibition space, a view of a specific wall surface 53 viewed from the front (that is, a front view) and a view viewed from a plane (that is, a plan view) are shown together.

In order to acquire the plane coordinates on the exhibition space of the wall surface 53, the four corner coordinates of the wall surface 13 may be used. If the wall surface 53 of the exhibition image 50 corresponds to the wall surface 13 of the spatial image 10, the four corner coordinates of the wall surface 13 may be used in the same manner as the four corner coordinates of the wall surface 53. . The plane coordinates define the width and height of the objects in the exhibition space.

In addition, the slope value of the wall surface 53 may be used to obtain depth coordinates on the exhibition space of the wall surface 53. The slope value of the wall surface 53 can be obtained at an angle of θ1 or θ2. The inclination value of the wall surface 53 can also be obtained using the analysis result of the spatial image 10 by the server 200 described above. That is, if the wall surface 53 of the exhibition image 50 corresponds to the wall surface 13 of the spatial image 10, the slope value of the wall surface 13 may be used equally as the slope value of the wall surface 53. . In the embodiment of the present invention, a left-handed coordinate system was used, but it will be apparent to those skilled in the art that it can be used by being modified to a right-handed coordinate system according to the embodiment.

The relative depth coordinates of the wall surface 53 on the exhibition space can be calculated using the plane coordinates of the wall surface 53, the width d of the wall surface 53, and various trigonometric functions, as shown in FIG. 16. In FIG. 16, for example, a relative depth difference z1-z2 between two corners of the lower portion of the wall surface 53 may be calculated. The width d of the wall surface 53 may be predetermined, or may be calculated using a fixed ratio of the wall surface 53 or the above-described slope value.

In some embodiments, in a process in which the slope value of the wall surface 13 is obtained, depth coordinates on the exhibition space of the wall surface 13 may be obtained. In this case, if the wall surface 53 of the exhibition image 50 corresponds to the wall surface 13 of the spatial image 10, the depth coordinates of the wall surface 13 may be used as the depth coordinates of the wall surface 53. have.

In some embodiments, in order to obtain 3D coordinates, a difference in depth between a user's viewpoint on a display space and a specific wall surface may be additionally considered.

According to an embodiment, the 3D coordinates may be obtained in the form of relative or absolute coordinates based on the user's viewpoint.

Subsequently, in step S720, the user terminal 100 generates 3D VR data 60 corresponding to the exhibition image 50 using the analysis result of the exhibition image 50.

Subsequently, in step S730, the user terminal 100 provides the 3D VR data to the user through the VR terminal 600 or directly.
