Abstract

A control method of an electronic device for modeling a 3D virtual space is disclosed. The control method includes the steps of: acquiring building information on at least one building; generating a skeleton representing a floor-by-floor cross-section of a virtual object matched to a building based on the number of floors, height, and floor-by-floor cross-section according to building information; and transforming the virtual object by performing at least one of rotation, reduction, and expansion of the skeleton generated with respect to at least one layer.

Description

Control method of an electronic device that transforms a virtual object by adjusting the skeleton matching each floor { CONTROL METHOD OF ELECTRONIC APPARATUS FOR DEFORMING VIRTUAL OBJECT BY ADJUSTING SKELETON MATCHING TO EACH FLOOR }

The present disclosure relates to a control method of an electronic device for modeling a three-dimensional virtual space, and more particularly, to a control method of an electronic device for adjusting the rotation angle and size of a skeleton generated for each floor according to building information.

Three-dimensional modeling (Modeling) can improve the limitations of two-dimensional information by visually increasing understanding and enabling three-dimensional analysis. In particular, 3D modeling may provide a realistic 3D virtual space to a user in implementing animations, games, and the like.

Meanwhile, in designing a 3D virtual space, in general, a developer/designer spends a lot of time to express individual virtual objects (eg, buildings, people, roads).

For example, assuming that a building is being designed, the specific location, shape, direction, and size of each building must be specified one by one, and the detailed details (material, window, floor, roof, etc.) within the building are also one. One needs to be drawn or set. In addition, if the design target extends to one city rather than one building, there is a difficulty in that numerous buildings must be individually designed.

In a situation in which the sense of reality of games/animations/CGs is gradually being leveled upward, it takes too much effort and time for developers/designers to build high-quality, detailed images.

Referring to FIG. 1 , the electronic device 100 may include a memory 110 and a processor 120 .

The electronic device 100 may correspond to various terminal devices such as a desktop PC, a notebook PC, a tablet PC, a smart phone, and a PDA.

The memory 110 may include various information related to modeling of a 3D virtual space. For example, the memory 110 may include information on various virtual objects located in the 3D virtual space.

The memory 110 may include building information for various buildings. The building information may include a location (eg, an address) of a building, a height, a cross-sectional view by height, a direction, an area, a building name, a use, and the like.

The building information may be information managed in association with at least one map representing an actual space.

For example, the building information may be information included in an open street map (OSM) open to at least one area that actually exists. OSM corresponds to an open-source participatory map service, and includes building information for various buildings located in each area.

Meanwhile, the building information may be managed in association with at least one map indicating a space defined in a virtual environment that does not actually exist. In this case, the building information may correspond to information about a virtual defined building.

The processor 120 is a configuration for overall controlling the electronic device 100 . Specifically, the processor 120 may perform operations according to various embodiments of the present disclosure by executing at least one instruction stored in the memory 110 while being connected to the memory 110 .

The processor 120 may include a general-purpose processor such as a CPU, an AP, or a digital signal processor (DSP), a graphics-only processor such as a GPU, a vision processing unit (VPU), or the like, or an artificial intelligence-only processor such as an NPU. The AI-only processor may be designed with a hardware structure specialized for training or use of a specific AI model.

Referring to FIG. 1 , the processor 120 may control the building information management module 121 , the 3D modeling module 122 , and the like. These modules may be implemented by a combination of software and/or hardware. On the other hand, these modules correspond to examples for defining functional blocks according to the functions of the processor 120 . In designing/defining the functions of the electronic device 100 , the module configuration in the electronic device 100 must be described above. It doesn't have to be built like a module configuration.

The building information management module 121 is a configuration for acquiring and managing the above-described building information.

As an example, the building information management module 121 may extract building information of buildings existing in the corresponding area from the OSM of a specific area corresponding to the actual space.

The 3D modeling module 122 is a configuration for building a 3D virtual space based on 3D image data, and may manage coordinates constituting the virtual space and information on virtual objects positioned at each coordinate.

For example, the 3D modeling module 122 may generate a virtual object corresponding to at least one building in a virtual space based on the building information obtained through the building information management module 121 . Specifically, the 3D modeling module 122 may generate a three-dimensional virtual object that matches an actual building based on the location, area, height, number of floors, cross-sectional view by height, etc. of the building included in the building information. In this case, a skeleton representing a cross-sectional view of each layer may be utilized, which will be described later with reference to the drawings.

2 is a flowchart illustrating a method of controlling an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 2 , the electronic device 100 may obtain building information on at least one building ( S210 ). Specifically, the electronic device 100 may obtain information on the number of floors, height, cross-sectional view for each floor, area, and the like of at least one building.

In this case, building information of at least one building may be input according to a user input.

For example, the electronic device 100 may extract building information of buildings existing in the corresponding area from the OSM of a specific area corresponding to the actual space.

As a specific example, the electronic device 100 may acquire OSM data including curve/flat geo by accessing at least one web page providing OSM. In this case, the electronic device 100 may extract only building data among OSM data, and as a result, building information for each building may be obtained.

In this case, the electronic device 100 may extract only building information (eg, size, area by height, height, number of floors, cross-sectional view by height) for configuring a skeleton of a building from the OSM data.

In addition, the electronic device 100 may generate a skeleton representing a cross-sectional view for each floor of a virtual object matching a building based on the number of floors, a height, and a cross-sectional view for each floor according to the building information ( S220 ). The skeleton may be composed of one or more points and/or lines representing a cross-sectional view for each floor of a virtual object matching a building. The skeleton may be a reference through which a specific design sample (eg, composed of one or more polygons) for a door, window, wall, etc. may be reflected in the virtual object. For example, the skeleton may be divided into a plurality of slots according to a floor unit, a side unit, and the like, and a door, a window, a wall, etc. may be generated for each slot.

Referring to FIG. 3A , the electronic device 100 may configure a skeleton in which a cross-sectional view of each layer constituting the virtual object is reflected.

In this case, with respect to at least one layer, the electronic device 100 may deform the virtual object by performing at least one of rotation, reduction, and enlargement of the generated skeleton.

As an embodiment, the electronic device 100 may reduce and/or enlarge the skeleton of each layer so that the cross-sectional area of each layer is different.

In relation to this, FIG. 3B is a diagram for explaining an operation in which the electronic device tapers the cross-sectional area of the skeleton for each layer according to an embodiment of the present disclosure.

Referring to FIG. 3B , as the layer of the virtual object increases, the electronic device 100 may reduce the skeleton representing the cross-sectional area for each layer so that the cross-sectional area of each layer gradually increases.

As a result, the virtual object whose cross-sectional area varies according to the height may be deformed.

Also, according to an embodiment, the electronic device 100 may deform the virtual object so that the rotation angle is slightly different for each layer.

In relation to this, FIG. 3C is a diagram for explaining an operation of variously setting a twist angle of a skeleton for each layer by an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 3C , as the number of layers of the virtual object increases, the electronic device 100 may rotate a skeleton representing a cross-sectional view for each layer so that the rotation angle varies by a predetermined angle for each floor.

In FIG. 3C , in the case of the left figure, the angular difference between the uppermost and lowermost layers is uniformly formed so that the angular difference between the uppermost and lowermost layers is 40°, and in the case of the right figure, the angular difference between the uppermost and lowest layers is 180° It shows a case in which the angular difference of each layer is formed uniformly so as to be implemented as .

Here, the electronic device 100 may set the maximum rotation angle of the uppermost layer of the virtual object according to the number of layers of the virtual object. The maximum rotation angle means an angle at which the uppermost layer can be rotated to the maximum with respect to the lowest floor under a setting in which the rotation angle gradually increases as one goes up one layer from the lowest floor.

Specifically, as the number of layers of the virtual object increases, the maximum rotation angle of the uppermost layer may be set to be larger, and the electronic device 100 may perform deformation under a condition that the rotation angle of the uppermost layer maintains the maximum rotation angle or less. For example, when the number of layers of the virtual object is 5, the maximum rotation angle of the top layer may be set to 50°, and when the number of layers of the virtual object is 15 layers, the maximum rotation angle of the top layer may be set to 150°.

Also, according to an embodiment, the electronic device 100 may classify the virtual object into a plurality of groups based on the layer of the virtual object, and set different patterns of changes in the cross-sectional area for each layer for each group.

Specifically, the electronic device 100 may classify a plurality of layers constituting the virtual object into a first group and a second group (eg, 1st to 10th floors: 1 group, 11 to 20th floors: 2 groups).

Here, in the electronic device 100, the cross-sectional area of each layer changes by a first value as the number of layers increases within the first group, and as the number of layers increases in the second group, the cross-sectional area of each layer changes at a second value (: first value) and different), it is possible to reduce or enlarge the skeleton representing the cross-sectional view for each floor.

In relation to this, FIG. 3D is a diagram for explaining an operation of variously setting a change pattern of a cross-sectional area of a skeleton for each layer by an electronic device according to an embodiment of the present disclosure.

For example, referring to the left figure of FIG. 3D, the virtual object is created so that the cross-sectional area decreases by a certain value for each floor as the number of floors increases from the first to the fifteenth floors, and the (reduced) cross-sectional area remains constant for the fifteenth or higher floors. can be deformed.

For example, referring to the figure on the right of FIG. 3D , based on the middle layer (ex. 18 layers), the cross-sectional area gradually decreases as the number of layers decreases for a section lower than the middle layer, and as the number of layers increases for a section higher than the middle layer, the higher the number of layers The virtual object may be deformed so that the cross-sectional area is gradually reduced.

As such, the electronic device 100 may variously deform the virtual object based on rotation, enlargement, reduction, etc. of a skeleton representing a cross-sectional view for each layer. For example, it is possible to deform a complex shape as shown in FIG. 4 .

Meanwhile, as an embodiment, the electronic device 100 may generate a plurality of virtual objects in a three-dimensional virtual space, and each virtual object may be configured with the above-described skeleton.

In relation to this, according to an embodiment, the electronic device 100 may receive a user input for selecting an area corresponding to an actual space. For example, the electronic device 100 may receive a user input for selecting a specific area or a specific area on the OSM. In this case, the electronic device 100 may select a corresponding zone according to a user input for setting an address (eg, Seoul, Gangnam-gu, Yeoksam-dong, etc.) of a specific zone. Also, the electronic device 100 may provide a map (eg, 2D, 3D) representing an actual space. In this case, the electronic device 100 may select a corresponding zone according to a user input for selecting at least one zone on the map.

As a specific example, FIG. 5A illustrates a map 510 included in the OSM and building information 510 ′ linked to the map 510 . On the OSM, building information 510' related to each area in the map 510 is included. In addition, path information related to each area in the map 510 is included on the OSM. The route information includes the location, width, and classification (eg, highway, bicycle path, sidewalk, etc.) of each route.

Referring to FIG. 5B , the electronic device 100 may display a corresponding map 510 and identify a region 511 selected according to a user input on the map 510 .

In addition, the electronic device 100 may obtain building information for each of a plurality of buildings included in the (selected) corresponding area (ex. 511 ). For example, when “Gangnam-gu” of “Seoul” is selected in the OSM, the electronic device 100 may extract building information on all buildings included in “Gangnam-gu”. As a specific example, the electronic device 100 may acquire OSM data including curve/flat geo by accessing at least one web page providing OSM. In this case, the electronic device 100 may extract only building data among OSM data, and as a result, building information for each building may be obtained. In this case, the electronic device 100 may extract only building information (eg, size, area by height, height, number of floors, cross-sectional view by height) for configuring a skeleton of a building from the OSM data.

Based on the obtained building information, the electronic device 100 may generate a plurality of virtual objects matching each of the plurality of buildings in the three-dimensional virtual space.

For example, referring to FIG. 5C , the electronic device 100 may collectively generate a plurality of virtual objects matching each building in the three-dimensional virtual space 520 . The virtual objects may be matched to each building included in the area 511 selected according to a user input in FIG. 5B .

Here, as in FIG. 3A , a skeleton representing a cross-sectional view of each layer may be generated according to a cross-sectional view for each layer of each virtual object.

As such, in a state in which a plurality of virtual objects are generated in the virtual space, the electronic device 100 may variously perform transformations corresponding to step S230 of FIG. 2 based on building information of the plurality of virtual objects.

Specifically, the electronic device 100 may identify whether a deformation-inducing condition is satisfied based on a distance between virtual objects, a degree of deformation of each virtual object, and the like. The deformation-inducing condition corresponds to a condition for triggering automatic deformation of the at least one virtual object, and when the deformation-inducing condition is satisfied, the electronic device 100 may automatically deform the at least one virtual object. Hereinafter, examples of the deformation-inducing condition will be described.

As an embodiment, the electronic device 100 may identify a distance between the virtual objects based on the location and area of each virtual object.

In this case, the electronic device 100 may identify at least one virtual object in which the shortest distance to another virtual object among the plurality of virtual objects is less than a threshold distance (a deformation inducing condition). Here, with respect to the identified virtual object, the electronic device 100 may deform the virtual object so that the cross-sectional area of each layer becomes gradually narrower as the layers increase (eg, FIG. 3B ). As a result, there is an effect that the distance or interval between virtual objects that are too close (eg, the distance is less than a threshold) appears relatively relaxed, and this operation may be automatically performed by the electronic device 100 .

Also, according to an embodiment, the electronic device 100 may calculate the degree of deformation of each of a plurality of virtual objects existing in the virtual space.

Here, the degree of deformation means the degree of deformation from the standard shape.

The reference shape may be, for example, a shape in which the angles and areas of the cross-sectional views of all layers are the same as in FIG. 3A .

In this case, the degree of deformation may be calculated based on the difference in area between the cross-sections for each layer and the difference in rotation angle of the cross-sections for each layer. For example, the greater the difference in the area of the cross-sectional view for each layer and the greater the difference in the rotation angle of the cross-sectional view for each layer, the higher the degree of deformation may be calculated.

Then, the electronic device 100 may calculate an average value of the degree of deformation of the plurality of virtual objects. If the average value of the degree of deformation of the plurality of virtual objects is less than the threshold (deformation inducing condition), the electronic device 100 may identify at least one virtual object having the lowest degree of deformation among the plurality of virtual objects.

In this case, the electronic device 100 may deform the identified virtual object by performing at least one of rotation, reduction, and enlargement of the skeleton with respect to the identified virtual object (a virtual object with a low degree of deformation).

Through this, when the overall degree of deformation of the virtual objects in the virtual space is low, the degree of deformation of at least one virtual object may be automatically strengthened, so that the overall degree of deformation of the virtual objects is low, resulting in an overall boring or uniform appearance. This can be prevented in advance.

Also, according to an embodiment, the electronic device 100 may identify deformation degrees of virtual objects located within a predetermined distance based on one virtual object, respectively, and calculate an average value and a deviation value of the identified deformation degrees. Here, when the identified deviation is less than the threshold deviation, the electronic device 100 may deform the corresponding virtual object such that the degree of deformation of the reference virtual object is further away from the average value. On the other hand, when the identified deviation is equal to or greater than the threshold deviation, the electronic device 100 may deform the corresponding virtual object so that the reference virtual object's deformation degree is closer to the average value. The electronic device 100 may perform this process based on each of the plurality of virtual objects.

In this case, the overall degree of deformation of the virtual objects may be harmoniously maintained in relation to the adjacent virtual objects.

Meanwhile, according to an embodiment, the electronic device 100 may select at least one landmark object from among the plurality of virtual objects based on the height and deformation degree of each of the plurality of virtual objects. The landmark object may be defined as a virtual object (eg, a virtual building) that symbolically represents at least one area in a virtual space.

For example, the electronic device 100 may select a virtual object having the highest height and/or the greatest degree of deformation as the landmark object, and may provide information on the selected landmark object to the user.

In relation to this, when a plurality of virtual objects exist in a virtual space constituting a specific city, the electronic device 100 may set the distribution of characters (eg, digital humans) in the virtual space as the center of the landmark object. For example, the electronic device 100 may set the positions of the characters such that the closer to the landmark object, the greater the density of the characters.

Also, the electronic device 100 may identify a deformation pattern of the landmark object and apply the identified deformation pattern to virtual objects located within a predetermined distance from the landmark object. The deformation pattern may consist of a pattern in which the area of the cross-sectional area for each layer changes (eg, the amount of change in the cross-sectional area for each layer), a difference in rotation angle of the cross-sectional view for each layer, and the like.

For example, when the difference in rotation angle between the lowest floor and the highest floor of the landmark object is 90°, the electronic device 100 sets the rotation angle (rotation angle between the lowest floor and the highest floor) of at least one virtual object located within a predetermined distance from the landmark object. The virtual object can be deformed so that the difference) is within a certain range (eg, ±30° based on 90°).

Meanwhile, the electronic device 100 may divide a skeleton representing a cross-sectional view for each floor into a plurality of slots according to a sub-building unit, a floor unit, a side unit, and the like. Each slot corresponds to a unit to which walls, windows, and doors constituting the virtual object can be applied. For each slot, an identification number (ex. USN: Unique Slot Number) may be designated.

For example, it is assumed that a virtual object representing one building includes two sub-buildings. Here, in the case of the skeleton part matching the fourth side of the 5th floor of the first sub-building, an identification number such as 1-5-4 may be assigned, which identifies the slot that will later become the editing unit of the custom design of the building It can be used as a number.

The electronic device 100 may perform a specific design operation by applying a design sample (eg, composed of one or more polygons) constituting a door, window, column, wall, etc. to each slot constituting the skeleton, and as a result, a virtual object can be implemented in the shape of a complete building.

However, even after design samples such as doors, windows, columns, and walls are reflected, the virtual object may be deformed due to deformation of the skeleton. For example, the virtual object may be deformed as a user input requesting transformation of the virtual object is received. As another example, at least one virtual object may be automatically transformed as the above-described transformation-inducing condition is subsequently satisfied in the process of sequentially additionally generating the virtual object.

In this case, the electronic device 100 may deform at least one of a wall, a window, and a door included in each of the plurality of slots constituting the deformed skeleton.

As such, the electronic device 100 may perform transformation on each of a plurality of virtual objects in the virtual space according to the various embodiments described above, and it is possible to design a virtual space including virtual objects of various shapes as shown in FIG. 6 . do.

Meanwhile, FIG. 7 is a block diagram illustrating a configuration of an electronic device according to various embodiments of the present disclosure.

The communication unit 130 may include circuits, modules, chips, etc. for performing communication with at least one external device in various wired/wireless communication methods.

The communication unit 130 may be connected to external devices through various networks.

The network may be a personal area network (PAN), a local area network (LAN), a wide area network (WAN), etc. depending on the area or size, and depending on the openness of the network, an intranet, It may be an extranet or the Internet.
