For example, the interface module 124 may provide the user of the service with a camera interface that moves the digital twin space in the first person and outputs the viewing point in the first person. The interface module 124 may provide a light source interface that allows the irradiation direction of the light source to be adjusted by the user in the digital twin space. The interface module 124 may allow the user to access the digital twin space with only a URL through gamification of a building based on WebGL.

Referring to FIG. 4 , the modeling module 121 may generate a digital twin space including a plurality of buildings in which the exterior of the building is implemented as a 3D texture based on 3D spatial data captured based on an actual map. The modeling module 121 may map address information of an actual map to a building in the digital twin space to specify the location of each building in the digital twin space.

Next, the modeling module 121 may obtain a plan view, a cross-sectional view, and an elevation view corresponding to at least one of a plurality of buildings included in the digital twin space ( S1020 ). For example, the modeling module 121 is based on the real address information mapped to the building implemented in the digital twin space and the authentication of the real building owner or resident (eg, comparison authentication between real estate registered image and service user information) corresponding to the real address information. It is possible to receive images of floor plans, sections, and elevations of the building from the owner.

Next, the modeling module 121 may generate a 3D spatial model of the building corresponding to the acquired building design based on the acquired floor plan, cross-sectional view, and elevation ( S1030 ). As an example, the modeling module 121 may generate a 3D spatial model by performing the operations of FIGS. 5 to 11 below.

5 to 7 are exemplary views of an operation of generating a spatial model for each floor based on a plan view according to an exemplary embodiment.

5 to 7, the modeling module 121 generates a spatial model of the first floor plan corresponding to FIG. 5 based on the plan view, and by generating a spatial model of the second floor plan corresponding to FIG. 6, respectively, You can create a spatial model for each floor.

To this end, the neural network module 122 may specify line segments and symbols described in the floor plan for each floor, and determine object information meaning the specified line segments and symbols from the drawing information DB 112 . For example, the neural network module 122 inputs the floor plan obtained to the neural network model learned based on the learning floor plan in which the class for line information and symbol information used in the design is labeled, and the line segments and symbols included in the plan view Location and type can be specified.

The modeling module 121 loads a 3D model of an object (eg, an inner wall and an outer wall, etc.) corresponding to the type of line segment included in the obtained plan view from the drawing information DB 112, and virtual can be created in space. The modeling module 121 loads a three-dimensional model of an object (eg, a sink, a chair, etc.) corresponding to the type of symbol included in the obtained plan view from the drawing information DB 112, and loads a virtual model corresponding to the symbol position of the plan view. can be created in space.

In this way, the modeling module 121 loads the three-dimensional model of the object corresponding to the lines and symbols included in the obtained floor plan for each floor into the virtual space, and generates a three-dimensional space model for each floor corresponding to each floor plan as shown in FIG. 7 . can do. The modeling module 121 may map a URL link for information on an actual product corresponding to the corresponding object to the 3D model object included in the spatial model for each floor. Accordingly, when a 3D model object is selected by the user in the digital twin space, the modeling module 121 may provide the user with a URL link for information of the corresponding object.

8 and 9 are exemplary views of an operation of generating an internal space model in which a spatial model for each floor is connected based on a cross-sectional view according to an embodiment.

8 and 9, the modeling module 121 applies the virtual height corresponding to the height information of each floor described in the cross-sectional view of FIG. 8 to the previously generated space model for each floor to the space model for each floor, and described in the cross-sectional view. According to the order of each floor, it is possible to generate an internal space model in which the space models for each floor are connected by a distance equal to the virtual height.

To this end, the modeling module 121 specifies the line segments and symbols described in the cross-sectional view of FIG. 8 through the neural network module 122, and can determine object information that the specified line segments and symbols mean from the drawing information DB 112. . For example, the neural network module 122 enters the obtained cross-section into the neural network model trained based on the cross-section for learning in which classes for line, symbol, scale, and orientation information used in the design are labeled, and is included in the cross-section. It is possible to specify the position and type of lines and symbols, and to determine scale and orientation information.

The modeling module 121 applies the virtual height of the object (eg, the height of the wall) corresponding to the type of line segment included in the cross-sectional view to the space model for each floor, and the space model for each floor based on the scale and orientation recognized in the cross-sectional view. Among the plurality of surfaces it has, the surface corresponding to the surface described in the cross-sectional view is determined, the arrangement surface of the space model for each floor is arranged based on the surface described in the cross-sectional view, and the space model for each floor is drawn according to the order of each floor described in the cross-sectional view. An interior space model can be created as shown in FIG. 9 by connecting the layers at a distance equal to the virtual height of the floor.

10 and 11 are exemplary views of an operation of generating an external space model for each side of a building based on an elevation view according to an embodiment.

10 and 11 , the modeling module 121 may generate an external space model of each side (eg, east side, west side, south side, north side) constituting the exterior of the building based on the elevation view. have.

To this end, the modeling module 121 specifies the line segments and symbols described in the elevation view of FIG. 10 through the neural network module 122, and can determine object information that the specified line segments and symbols mean from the drawing information DB 112. . For example, the neural network module 122 inputs the obtained elevation to the neural network model learned based on the elevation for learning in which classes for lines, symbols, scales, and orientation information used in the design are labeled. It is possible to specify the position and type of lines and symbols, and to determine scale and orientation information.

The modeling module 121 creates a three-dimensional model of an object (ex. exterior wall, window, railing) corresponding to the type of line and symbol included in the elevation view in a virtual space, and each side (ex. east side) constituting the exterior of the building face, west face, south face, north face) and create an external space model connecting each face according to azimuth and scale. Then, the modeling module 121 is based on the orientation and scale information of the building design, the height information of each floor included in the external space model generated by the elevation view, and the internal space model generated by the floor plan and the cross-sectional view. By connecting the height information of each floor to correspond to each other, it is possible to create a three-dimensional space model in which both the inside and outside of the building are realized.

12 is an exemplary diagram of an operation of substituting a 3D spatial model into a digital twin space according to an embodiment.

Referring to FIG. 12 , the control module 123 is located in a three-dimensional space at a location of a building corresponding to information of a building design obtained from among a plurality of buildings (eg, buildings in the state of FIG. 4 ) in which a 3D appearance is implemented in a digital twin space. A model may be substituted (S1040). The control module 123 compares the address information mapped to the building in which the 3D exterior of the digital twin space is implemented with the address information mapped to the obtained building blueprint, and the three-dimensional space generated according to the process of FIGS. 5 to 11 . model can be substituted.

On the other hand, if the 3D space model generated by the S1030 operation is generated in a virtual environment (project) different from the digital twin space created by the S1010 operation, a heterogeneous size difference may occur when substituting the 3D spatial model into the digital twin space. can To solve this, the control module 123 may reset the size of the 3D space model to be substituted so that it corresponds to the size of the 3D exterior implemented in the digital twin space. For example, the control module 123 controls the outermost part of the three-dimensional space model so that the difference between the volume of the building implemented with the 3D exterior in the digital twin space and the volume of the outermost texture of the three-dimensional space model is within a preset range. By adjusting the volume, it can be substituted into the digital twin space.

The interface module 124 may provide a digital twin space-based application service in which the three-dimensional space model is reflected (S1050)

As an example, the interface module 124 may provide a camera interface that moves the interior of a building in which a 3D space model is reflected in a digital twin space from a first-person view. When the first-person view is located in a portion corresponding to the 3D model object corresponding to the stairs of the building design, the interface module 124 provides a space model for each floor of the currently located view based on the movement direction of the first-person view manipulated by the user. You can output a space model for each floor from the location to the top or bottom in the first person view.

For example, the interface module 124 may control the movement of the first-person view to be permitted only to a user account that has received permission from a user account corresponding to an actual building owner or a tenant of the corresponding building.

For example, when the first-person view views an object corresponding to a window in the 3D space model, the interface module 124 may output the external digital twin space of the 3D space model to the window portion as a first-person view. .

For example, when different users use the camera interface in the 3D space model of the same building at the same time, the interface module 124 displays the positions of the first-person viewpoints of different users, and voice conversation or chatting between different users. A conversation interface for conducting a conversation may be provided.

As an example, when different users use the camera interface in a 3D space model of the same building at the same time, the interface module 124 is configured to display a predetermined 3D space at any point inside the 3D space model. By creating a model object, it is possible to provide a game interface for treasure hunting.
