Spatial data includes the type, location, size, and spatial topological relationship with other terrain elements of the terrain element, and attribute data is data on the properties of the terrain element, including quantitative data containing mathematical meaning, map name, period, etc. Includes qualitative data necessary to describe the object, such as labels. For example, geographic information can be obtained using 3D spatial information provided by the National Geographic Information Institute under the Ministry of Land, Infrastructure and Transport.

Object information may include real estate such as buildings, parks, squares, roads, overpasses, and bridges, and movable assets such as traffic lights, statues, sculptures, airships, balloons, cruise ships, and automobiles. For example, object information about real estate can be obtained through geographic information, and object information about movable assets can be obtained through being included in geographic information or entering separate object information.

Preferably, the virtual reality of this embodiment may be based on digital twin technology that implements machines, equipment, objects, etc. from the real world into the virtual world in the computer, but is not necessarily limited to this.

The virtual reality server 100 of this embodiment interacts with the user client 200, the advertiser client 300, and the payment institution system 400 through the network 1.

The user client 200 is a user client that connects to the virtual reality server 100 through a network 1 such as the Internet or an intranet and uses various services based on virtual reality (e.g., mock exam, geographical simulation, etc.). The user may be a user registered with the virtual reality server 100 through a normal user membership registration process, but is not limited thereto.

The advertiser client 300 connects to the virtual reality server 100 through a network 1 such as the Internet or an intranet and requests that an advertisement be displayed based on a pre-designated object within a three-dimensional coordinate space implemented in virtual reality. It is an advertiser's client. An advertiser is an advertiser registered on the virtual reality server 100 through a normal advertiser member registration process.

The payment institution system 400 is a system that processes the payment process for advertisers to pay advertising fees to the virtual reality server 100 for execution of requested advertisements. It can be a typical bank server, credit card company server, etc. there is. Various known advertising fee payment methods, such as cash transfer method, credit card payment method, and point accumulation method, may be applied. Depending on the advertising fee payment conditions, the advertising display time, period, display cycle, etc. can be set in various ways.

From a functional point of view, the virtual reality server 100 of this embodiment implements virtual reality in a three-dimensional coordinate space based on geographic information and object information to serve as an advertiser client 300, a user client 200, or an administrator client (not shown). A virtual reality implementation module 102 that visually provides information on the screen, an advertisement registration module 104 that registers and manages advertisement information requested from the advertiser client 300, and any one within a three-dimensional coordinate space implemented in virtual reality. An advertisement implementation module 106 that displays registered advertisement information based on the shadow of the object, an operation module 108 that provides overall management functions of the virtual reality server 100, such as member registration and various member management modes, and administrator mode. Includes.

For example, the advertisement registration module 104 and/or the advertisement implementation module 106 may be distributedly implemented in the form of a separate advertisement server that is network-linked with the virtual reality server 100.

In addition, the virtual reality server 100 of this embodiment includes a geographic information DB 112 that stores and updates geographic information for implementing virtual reality, and stores and updates object information for implementing various objects included in virtual reality. It includes an object information DB 114 that manages, and an advertising information DB 116 that stores and updates and manages advertising content requested from the advertiser client 300 and advertising period/time/advertiser information/payment information.

For example, the geographic information DB 112 and the object information DB 114 may be provided from a separate geographic information providing server (eg, National Geographic Information Institute server) that is network-linked with the virtual reality server 100.

For example, the advertising information DB 116 may be stored and managed in a separate advertising server that is connected to the virtual reality server 100 and a network.

The advertising information DB 116 may store and manage advertising content corresponding to the advertising content and advertising period/time/advertiser information/payment information corresponding to the advertising request content.

Advertising content can be input from the advertiser client (300) when applying for advertising information, or based on basic advertising information (e.g., advertising image, advertising text, advertising video, advertising voice, etc.) input from the advertiser client (300). Content may be automatically or manually created using a content creation tool provided by the virtual reality server 100.

The object on which specific advertising content is matched to which advertisement will be displayed can be inputted from the advertiser client 300 when applying for advertising information, or the advertising-object based on matching rules preset in the virtual reality server 100. A matching relationship may be established. One advertising content may be displayed for one or more objects, and conditions regarding the display time or cycle may be set automatically or manually.

Referring to FIG. 3, from a hardware perspective, the virtual reality server 100 of this embodiment includes a memory 2 that stores one or more instructions and a processor 4 that executes the one or more instructions stored in the memory 2. It is a computing device on which a computer program stored in a medium is executed to execute a method of providing advertisements in virtual reality.

4 to 8 are schematic diagrams for explaining an advertisement providing method according to an embodiment of the present invention.

As a preliminary step in providing advertisements, the advertiser client 300 connects to the virtual reality server 100 through a network 1 such as the Internet or an intranet, based on a pre-designated object within a three-dimensional coordinate space implemented in virtual reality. and request that the advertisement be displayed.

For this purpose, the advertiser can register as an advertiser on the virtual reality server 100 through a normal advertiser member registration process.

For example, an advertiser who wants to display an advertisement about chicken or beer can select the sports stadium object and request the advertisement by setting the weekend time when sports games are mainly held as the advertisement time.

The advertising information DB 116 of the virtual reality server 100 stores advertising content corresponding to the advertising content and advertising period/time/advertiser information/payment information corresponding to the advertising request.

For example, advertising content can be input from the advertiser client 300 when applying for advertising information. As another example, advertising content may be manually or automatically created in the form of content using a content creation tool provided by the virtual reality server 100 based on basic advertising information input from the advertiser client 300.

For example, an advertiser who wants to display an advertisement about chicken or beer logs in to the virtual reality server 100 and submits advertising content including a photo image of chicken or beer, advertisement text, advertisement video, etc. when applying for advertisement information. You can enter .

Afterwards, the following advertisement display provision steps are executed.

In step 1), the virtual reality server 100 displays a shadow 20 for an object 10 in a three-dimensional coordinate space implemented in virtual reality.

For example, the object 10 in virtual reality may be a three-dimensional object implemented based on a polygon mesh. A point with a position in three-dimensional space is a vertex, a straight line connecting vertices is an edge, and three or more vertices gathered together to form a face are polygons. This thing that comes together to form one three-dimensional object is called a polygon mesh. A polygon mesh can be viewed as defining an object in three-dimensional space.

The shadow 20 may be configured to be displayed only on the ground (floor) of virtual reality. In this case, the shadow 20 is in the form of a two-dimensional flat object rather than being implemented as a three-dimensional object based on a polygon mesh. It is desirable to implement this as:

For this purpose, the shadow 20 has its shape and form in real time or at a preset cycle based on the position of the virtual sun (S) in virtual reality, the geographical location (latitude, longitude) of the object 10, date, time, etc. Direction can change.

Step 1) may be structured in more detail as follows.

In step 11), the virtual reality server 100 defines the shape of the object 10 based on three-dimensional coordinates based on the state in which the object 10 is viewed in the direction of irradiation of virtual sunlight (SL). Extract the vertex (12). (state (a) in Figure 4)

The virtual reality server 100 defines a three-dimensional coordinate space to define the virtual reality space based on geographic information and object information, and this three-dimensional coordinate space can be viewed as a world coordinate system of the virtual reality space.

Vertices that define the shapes of all objects in the virtual reality space based on the world coordinate system of the virtual reality space have three-dimensional coordinate information based on the world coordinate system.

For example, if the object is a rectangular parallelepiped as shown in FIG. 4, the vertices defining the shape of the object may be a total of eight vertices. If the object has a more complex shape than a cuboid, it can have more than 8 vertices in total, and if the object has a simpler shape than a cuboid, it can have fewer than 8 vertices in total.

As a modified example, a known object lightweight process may be included in the extraction process of the vertex 12 in order to increase the computation speed for generating the shadow 20 in this embodiment. As an example of an object lightweight technique, the edge collapse technique, which simplifies the information defining an object by reducing the number of vertices and edges by merging two vertices forming an edge into one, is widely used.

For example, the cuboid object in (a) of Figure 4 has vertices (0,0,0), (x,0,0),..., (x,y, z) consists of a total of 8 vertices, and in step 11), the coordinates of a total of 8 vertices are extracted.

For reference, in the case of the rectangular object in Figure 4(a), for convenience of explanation of vertex coordinates, instead of the coordinates of the world coordinate system of the object, the coordinates of one vertex are exemplified as (0,0,0), and the coordinates of one vertex are illustrated as (0,0,0), and the coordinates of one vertex are illustrated as (0,0,0). The coordinates of the vertices are illustrated in the form of relative coordinates based on vertex (0,0,0).

In step 12), the virtual reality server 100 determines the depth value among the three-dimensional coordinate elements of each vertex 12 based on the state in which the object 10 is viewed in the direction of irradiation of virtual sunlight (SL). Make two-dimensional coordinates by removing the coordinate elements that define . (state (b) in Figure 4)

For example, the coordinate element that defines the depth value in the rectangular parallelepiped object in (a) of FIG. 4 is a y-coordinate element, so the y-coordinate element is removed from the 3-dimensional coordinates of each vertex and converted into 2-dimensional coordinates. For example, vertex (0,0,0) is two-dimensionally coordinates as (0,0), vertex (x,0,0) is two-dimensionally coordinates as (x,0), and vertex (x, y,z) is two-dimensionally coordinated as (x,z).

In step 13), the virtual reality server 100 extracts the outline by applying the Convex Hull algorithm based on the coordinate elements of each vertex 12 in two-dimensional coordinates. (state (c) in Figure 4)

The convex Hull algorithm is a known algorithm designed to create a convex polygon using some of the points when there are several points on a two-dimensional plane, but to include all points inside the convex polygon.

In step 14), the virtual reality server 100 defines the extracted outline as a two-dimensional polygon for displaying a shadow 20. (state (d) in Figure 4)

In step 15), the virtual reality server 100 virtually matches the position of the vertex 12 defining the bottom of the object 10 and the bottom of the two-dimensional polygon. (state (e) in Figure 4)

For example, in the state (e) of FIG. 4, the position of the vertex 12 defining the bottom of the object 10 illustrated on the left and the bottom of the two-dimensional polygon illustrated on the right are virtually matched.

16) Adjust the length of the two-dimensional polygon based on the irradiation direction of virtual sunlight (SL). (state (f) in Figure 4)

For example, in the state (f) of FIG. 4 , a two-dimensional polygon extending longer than the object 10 is illustrated on the left, and a two-dimensional polygon reduced to be shorter than the object 10 is illustrated on the right.

The long two-dimensional polygon on the left of the state in (f) of Figure 4 is formed at times when the sun's altitude is low, as shown in (f3) of Figure 5, and the short two-dimensional polygon on the right is formed at times when the altitude of the sun is low, as shown in (f2) of Figure 5. It can form at high altitude times.

Steps 11) to 16) are performed by computational processing of the processor 4 on the memory 2 of the virtual reality server 100, and are displayed visually on the screen of the virtual reality server 100 or the screen of the user client 200. Therefore, this process does not need to be implemented.

In step 17), the virtual reality server 100 places a length-adjusted two-dimensional polygon on the floor in the opposite direction to the direction of irradiation of virtual sunlight (SL), within a three-dimensional coordinate space implemented in virtual reality. A shadow (20) is displayed by adding color. (state (g) in Figure 4)

Figure 5 illustrates variously displayed shadows 20 according to the irradiation direction of virtual sunlight (SL).

Preferably, in the implementation process of step 17), the shadow 20 of one object 10 generated according to the irradiation direction of virtual sunlight (SL) in the three-dimensional coordinate space is projected onto another adjacent object 10. '), the outline 22 of the shadow 20 is corrected so that the shadow 20 of one object 10 does not invade the bottom area of the other object 10. (state in Figure 7)

Figure 7 illustrates a case where the shadow 20 of object 10 invades the floor area of another adjacent object 10'. In this case, the shadow 20 of object 10 is reduced so as not to invade the floor area of another adjacent object 10' ( to cutting) is corrected.

The reason for executing this correction process is that if the shadow 20 of object 10 is created in a state that invades the bottom area of another adjacent object 10', the advertising content 30 displayed in the area of the shadow 20' is created in a state that invades the bottom area of another adjacent object 10'. This is because problems may occur in the visual delivery effect of the advertisement by invading the bottom area or the outer surface of the object.

In step 2), the virtual reality server 100 displays advertising content 30 preset for the object 10 in an area that at least partially overlaps the shadow 20 of the object 10. (state (h) in Figure 4)

Preferably, the shadow 20 of the object 10 changes shape and direction according to a change in the irradiation direction of virtual sunlight (SL) within the three-dimensional coordinate space, and the advertising content 30 changes. The display state changes based on the shape and direction of the shadow 20. When virtual reality is implemented with digital twin technology, the shadow 20 is created in real time or based on the location of the virtual sun (S) in virtual reality, the geographical location (latitude, longitude) of the object 10, date, time, etc. The shape and direction change according to a preset period, and the display state of the advertising content 30 also changes based on the change in shape and direction of the shadow 20.

Preferably, the advertising content 30 is displayed in the inner area of the outline 22 of the shadow 20 of the object 10.

For example, the advertising content 30 is displayed by adjusting the content source defined to have a rectangular arrangement structure to have the maximum size in the inner area of the outline 22 of the shadow 20 of the object 10.

Figure 6 illustrates the display state of this advertising content 30. (h1) in FIG. 6 illustrates a case where the content source stored in the advertising information DB 116 has a long rectangular shape, and (h2) in FIG. 6 illustrates a case where the content source stored in the advertising information DB 116 has a shape close to a square. A case having a rectangular shape is exemplified. Each content source is displayed adjusted to have a maximum size in the inner area of the outline 22 of the shadow 20 of the object 10 at a specific viewpoint.

For example, the content source may be defined so that one or more of images, text, and videos have a preset arrangement structure.

Preferably, the arrangement structure is defined so that at least one of an image, text, and video is placed inside the rectangular virtual outline 32.

The content source illustrated at the top of FIG. 8 illustrates a case where the image 34-1 and the text 34-2 are defined to be arranged vertically inside the rectangular virtual outline 32.

Meanwhile, one advertising content 30 is displayed in the shadows 20 of two or more objects 10, and the content source of the advertising content 30 is determined according to the shape of the shadow 20 of each object 10. is displayed in a responsive manner.

For example, the arrangement structure may be configured to preset at least one of the size and resolution of the image, the size and line break of the text, and the size and resolution of the video according to a change in the width-to-height ratio or a change in size of the virtual outline. It is configured to change and display in a responsive manner based on set change rules.

(a), (b), and (c) illustrated at the bottom of FIG. 8 show that the content source illustrated at the top of FIG. 8 changes the size and size of the image according to a change in the width-to-height ratio or a change in size of the virtual outline. A case where one or more of resolution, size and line breaks of the text, and size and resolution of the video are changed in a responsive manner based on a preset change rule is exemplified.

For example, the content source illustrated in the upper part of FIG. 8 is stored in the advertising information DB 116 such that the image 34-1 and the text 34-2 are arranged vertically inside the rectangular virtual outline 32. It is a content source that is registered to be displayed by matching the shadows of two or more objects (10) at a preset time at the advertiser's request.

When the shadow of the object 10 is a rectangle extending horizontally as shown in (a) of FIG. 8, the content source illustrated in the upper part of FIG. 8 changes to be responsive so that the image is located on the left and the text is located on the right. can be displayed.

When the shadow of the object 10 is a rectangle extending longitudinally as shown in (b) of FIG. 8, the content source illustrated in the upper part of FIG. 8 has a narrower upper image width and changes to the text size and/or The line break state can be changed and displayed responsively so that it is aligned with the vertical outline.

When the shadow of the object 10 is a rectangle that extends laterally as shown in (c) of FIG. 8, the content source illustrated in the upper part of FIG. 8 maintains the basic arrangement, but has a display screen size that is further expanded in the horizontal direction. It can be displayed in a responsive manner.

The change rule for this responsive display is one of image size and resolution, text size and line breaks, and video size and resolution depending on the change in the width-to-height ratio or size of the web content in the publicly known responsive web. It can be implemented with a configuration similar to a known algorithm for changing the ideal.

Through the above configuration, for one object, the shape and size of the shadow change according to the change in date and/or time zone, and the size and arrangement of the advertising content can also change responsively accordingly.

Alternatively, in the same time zone, for two or more objects with different positions or shapes, the shape and size of the shadow are generated differently for each object, and accordingly, the size and arrangement of advertising content with the same content source are also different for each object. They can be displayed differently and responsively.
