Conventionally, a two-dimensional method such as a map has been used to display a geographic space. Nowadays, the visualization of a space using the concept of 3D is becoming common. Visualization of a space incorporating a three-dimensional concept is advantageous in that it can intuitively recognize the space and intuitively display the characteristics of the space.

One of the three-dimensional visualization of geographic space is a method of obtaining data and visualizing it through photographing using satellites or aircraft. However, such a method becomes expensive, and it is not suitable for processing the obtained data to express various expressions.

However, this is not intended to limit the present invention to a specific form of disclosure, it should be understood to include all changes, equivalents, and substitutes included in the spirit and scope of the present invention. The terms used in the present application are only used to describe specific embodiments, and are not intended to limit the present invention.

Hereinafter, a 3D visualization system according to an embodiment of the present invention and a 3D visualization method using the same will be described in detail with reference to the drawings. In the present specification, the same reference numerals are assigned to the same and similar configurations even in different embodiments, and the description is replaced with the first description.

The 3D visualization system 100 according to an embodiment of the present invention includes a geodata generation unit 1, a style data generation unit 2, a layer data generation unit 3, a spatial data generation unit 4, and data rendering. It includes part (5).

The geodata generation unit 1 extracts location information and feature information of a visualization target from geographic data, and generates geo data including location information and feature information. Geographic data can use generally known geographic data, and from the information included in this geographic data, information related to the location of the object to be displayed and information related to the characteristics of the object such as buildings, natural objects, and the number of populations are extracted. Create

The style data generation unit 2 generates style data to be displayed by adding a style to the corresponding characteristic according to the characteristic information of the visualization object generated by the geodata generation unit 1. Examples of style data include color, size, and transparency, and this style can be assigned to geodata.

The layer data generation unit (3) matches the geo data generated by the geo data generation unit (1) and the style data generated by the style data generation unit (2), collects the same type of data among the matched data, and designates the layer data as a group. Create After the style data is added to the geo data through the layer data generator 3, data having a common point may be designated as a group.

The spatial data generation unit 4 generates spatial data for defining a form in which layer data is displayed in space. The spatial data generation unit 4 generates data defining a center point, a viewpoint, etc., and converts the layer data into various forms to be displayed.

The data rendering unit 5 matches layer data and spatial data, renders, and displays the rendered result on a web browser. By the data rendering unit 5, the layer data is converted into a form prescribed by the spatial data and displayed on a web browser.

Hereinafter, the configuration of each unit will be described in detail with reference to the drawings.

1 is a block diagram of a 3D visualization system according to an exemplary embodiment of the present invention, and FIG. 2 is a detailed block diagram of components of the 3D visualization system according to the exemplary embodiment shown in FIG. 1.

As described above, the geodata generation unit 1 extracts location information and feature information of the object to be visualized from the geographic data, and generates geodata including location information and feature information.

Geographic data may be data related to a three-dimensional geographic space as generally displayed on a map, or may be regional information data representing statistics of a region. The geographic data may use known geographic data stored in a file such as GeoJSON or a database such as postGIS.

In order to generate a geographic space as geodata, the geodata generation unit 1 may include a location data generation unit 11 and a characteristic data generation unit 12.

The location data generation unit 11 extracts and generates location information including the latitude and longitude of the object to be visualized from geographic data, and the characteristic data generation unit 12 generates characteristic information including the general name and size of the object. It is generated by extracting from geographic data.

Geographic data known in relation to the geographic space includes information on various features of the object together with the geographic location of the object. Only specific information is selectively collected from this geographic data to generate geodata.

Geographic data includes location data such as latitude and longitude, and how many objects exist at the location, such as roads, buildings, and natural objects, and information on the characteristics of the object. It contains data on features such as layer recognition.

Here, the location data generation unit 11 generates location information including the latitude and longitude of the object, and the characteristic data generation unit 12 extracts and generates characteristic information including the general name and size of the object. For example, in the case of a building, geodata in the form of (latitude, longitude, building (corresponding to general name), number of floors (corresponding to size)) is created, and in the case of road (latitude, longitude, road (corresponding to general name)) , Street (corresponding to the size)). In this way, it is possible to create geodata for various artifacts and natural objects.

Meanwhile, the characteristic data generation unit 12 may include a key extraction module and a value extraction module to generate characteristic data of an object. The'key' represents central data that can represent the characteristics to be found and can be set by the user. 'Value' represents the data of the lower level of the'key', which can also be set by the user. It is possible to extract characteristic data from geographic data by setting'key' and'value'. For reference, in the above description,'key' is the building and road, and'value' is the number of floors and road.

On the other hand, in the case of geographic data such as regional information, the data that divides the administrative area is used as the location information to be visualized, and the statistical data (various statistical data such as the number of population and sex ratio) in the administrative area is used as characteristic information. Can be created.

As described above, the style data generation unit 2 generates style data to be displayed by adding a style to the corresponding characteristic according to the characteristic information of the visualization object generated by the geodata generation unit 1.

The style data generation unit 2 may include a size calculation unit 21, an effect designation unit 22, and a color designation unit 23 in order to add and display a style in a geographic space.

The size calculation unit 21 calculates a size for displaying the object based on characteristic information on the size of the object to be visualized. For example, a function that roughly calculates the height by doubling the characteristic data of the number of floors in a building or by assigning 20 for a small road with a 5-ro boulevard (large road) according to the characteristic data of the road size. Do it.

The effect designating unit 22 designates a visual effect for displaying an object based on the general name of the object among characteristic information of the object. Here, the generic name is a concept in the broad sense that refers to the object, and in the above example, it corresponds to buildings and roads. Accordingly, for example, in the case of a building, the transparency can be increased, in the case of a road, the transparency can be decreased, and vice versa.

The color designating unit 23 designates a color for displaying an object based on the general name of the object among characteristic information of the object. For example, buildings can be displayed in blue and roads can be displayed in gray.

Such size calculation, effect designation, and color designation can be made by user designation. By generating such style data, it is possible to display geodata in a desired form (see FIGS. 6 to 8). In detail, it is possible to define what shape and size a layer having a specific characteristic or an object of a corresponding layer should have in a 3D space in which rendering is performed through characteristic information of the style data. Meanwhile, in the case of area information data, characteristic data can be displayed by designating a size, an effect, and a color similarly (see FIG. 9).

As described above, the layer data generation unit 3 matches the geo data generated by the geo data generation unit 1 with the style data generated by the style data generation unit 2, and collects the same type of data among the matched data. Create the layer data designated as a group. The layer data generation unit 3 may include a matching unit 31 and a layer data generation unit 32.

The matching unit 31 matches the generated style data with geodata to which the style data is to be visualized. Data to which style data has been assigned to geodata can be displayed as follows. For example, in the case of a road, it can have the form of (latitude, longitude, road, street)-(road width 20, gray, opaque), and in the case of a building, (latitude, longitude, building, number of floors)-(number of floors× It can have a shape of 3 (height), blue, and transparent.

The layer data generation unit 32 generates layer data by grouping data in which characteristic information of geodata is common among matched data of visualization targets among data matched with geodata and style data. For example, layer data can be created by grouping data with characteristic information of'daero', and another layer data can be generated by grouping data with characteristic information of'building'.

For reference, a city area model to which layer data having different styles is applied is shown in FIGS. 6 to 8. Layers here are buildings, roads, parks, etc. Meanwhile, in FIG. 9, a regional statistical model displayed by applying layer data is shown. Here, the layers include the boundary polygon layer and the living population point layer for each building.

As described above, the spatial data generation unit 4 generates spatial data for defining a form in which layer data is displayed in space.

The spatial data generation unit 4 generates data for setting a reference point of the space, a viewpoint of the space, and a range of the space in order to set the characteristics of the space itself. To this end, the reference point setting unit 41, And a time point setting unit and a range designating unit 43.

A reference point for displaying layer data in space is set through the reference point setting unit 41. In detail, it is set where the reference point of the space to be built is in the actual location (eg, latitude, longitude).

Meanwhile, a viewpoint in which the layer data is displayed in space is designated through the viewpoint setting unit, and a range in which the layer data is displayed in space is designated through the range designating unit 43. Through this, like the reference point, the viewpoint or range of the space to be constructed is set in the real position.

Accordingly, after the data is rendered, the display form can be varied. Accordingly, the spatial data rendering unit to be described later converts a layer and an object to be loaded into coordinates in the rendering space, while designating the shape and view of the space.

Meanwhile, as described above, the data rendering unit 5 matches layer data and spatial data, renders, and displays the rendered result on a web browser.

To this end, the spatial data rendering unit 5 includes a spatial object generating unit 51, a layer object generating unit 52, and an object matching unit 53.

The spatial object generation unit 51 generates a spatial object in which coordinates are transformed by applying a form prescribed in spatial data. Specifically, the spatial object creation unit 51 loads the spatial data constructed by being connected to the storage device to the storage device, and creates objects defining a space such as a reference point, a viewpoint, and a range through coordinate transformation based on the loaded spatial data. It will reset.

The layer object generation unit 52 generates a layer object whose coordinates have been transformed to fit a spatial object from the layer data. Specifically, the layer object generation unit 52 loads the layer data constructed by being connected to the storage device to the storage device, and converts the loaded layer data to the coordinates so that it can correspond to the spatial object to form a layer, such as buildings, markers, and roads. Etc. objects are reset.

Here, the memory device may use a memory device provided in hardware to which the present system is applied.

The spatial object and the layer object created in this way are matched with each other through the object matching unit 53 and displayed through a web browser. Examples displayed as described above are shown in FIGS. 6 to 9, and FIG. 5 conceptually shows each generated data and a result of rendering it.

Hereinafter, a method of 3D visualization of a space using the above 3D visualization system will be described in detail with reference to the drawings.

3 is a flowchart illustrating a process of generating and rendering data in a 3D visualization system according to an embodiment of the present invention.

A 3D visualization method according to an embodiment of the present invention includes a first step (S1) of generating geodata, a second step of generating style data (S2), a third step of generating layer data (S3), and space. It includes a fourth step (S4) of generating data and a fifth step (S5) of rendering and displaying data. Here, the first to fourth steps are not sequentially performed and each step may be performed independently.

In the first step, location information and feature information of the object to be visualized are extracted from geographic data, and geodata including location information and feature information is generated.

The creation of such geodata is performed when there is no existing geodata, and if geodata that can be used for the visualization target is established, the existing geodata is read and It can be used or created by appropriate reconfiguration. If some of the geodata are not built, it is also possible to create and add only empty geodata. On the other hand, the creation of geodata is also possible by user input. The generation of geodata is performed by the geodata generation unit 1 described above.

In the second step, style data to be displayed by adding a style to the corresponding characteristic according to the characteristic information of the visualization object generated in the first step is generated.

In the case of style data, as with geodata, previously created data can be used, and style data can be created when there is no existing data available or when a new style needs to be specified. This is performed by the style data generation unit 2 described above.

In the third step, the geodata generated in the first step and the style data generated in the second step are matched, and the same type of data is collected among the matched data to generate layer data designated as a group.

Layer data that has already been created can also be used, and layer data can be created when there is no existing data or when it is necessary to designate a new layer. Layer data is generated by selecting and matching geo data and style data and designating the same type data as a group, which is performed by the layer data generation unit 3 described above.

In the fourth step, spatial data is generated to define a form in which the layer data is displayed in space. In the case of spatial data, the existing spatial data can be used.

This step includes defining “what layer” the spatial data is composed of, and defining a form in which this layer is displayed in space. As described above, the spatial data has data related to the space itself for configuring the space, such as setting a reference point. Therefore, it is necessary to define which layer is included in the corresponding space. In the subsequent rendering process, an empty space is created with the spatial data corresponding to the layer, and the space is completely built by rendering the layer by importing the layer data included in the space. You can perform the process of becoming.

In this way, it is possible to use geodata, style data, layer data, or spatial data that have been previously generated, or to additionally generate and use new data.

Meanwhile, each data need not necessarily be created according to the presented flow. Since each data can be edited, it can be independently created and completed later. For example, after creating layer data and creating style data later, new style data can be applied to layer data, and other data can be applied as well.

In the fifth step, the layer data and spatial data are matched and rendered, and the rendered result is displayed in a web browser.

4 is a flowchart illustrating a process of rendering data in a 3D visualization system according to an embodiment of the present invention.

Specifically, the fifth step includes loading spatial data (S51), creating spatial objects (S52), loading layer data (S53), creating layer objects (S54), and rendering space. It includes a step (S55). This is performed by the data rendering unit 5 described above.

In the step of loading the spatial data, the spatial data generated in the fourth step is loaded into the first database. The generated spatial data is loaded and stored in the first database.

In the step of creating a spatial object, a spatial object is created by performing coordinate transformation on the spatial data loaded in the first database according to the center, viewpoint, and range of the space. Accordingly, objects that define a space (eg, a scene, a camera, a spatial rendering position, a spatial center, etc.) can be created based on spatial data.

In the step of loading the layer data, the layer data created in the third step is loaded into the second database. The generated layer data is loaded and stored in the second database.

In the step of creating a layer object, a layer object is generated by performing coordinate transformation with respect to the visualization objects grouped in the same group in the layer data loaded in the second database so as to correspond to the spatial object created in the above-described step. Accordingly, objects (eg, buildings, markers (objects for designating a specific location), roads, etc.) constituting a layer based on spatial data may be created.

In the rendering of the space, the space containing the object to be visualized is rendered on the web browser by combining the created spatial object and the layer object. Accordingly, it is possible to visualize a three-dimensional space on a web browser.

Here, after loading data, spatial objects and layer objects are created, and the rendering of objects is continuously performed by the web browser, so that it is possible to visualize the 3D space seamlessly and quickly.

On the other hand, according to the fifth step, in addition to the result displayed on the web browser, a sixth step of adding and displaying information related to the visualization object extracted from geographic data in two dimensions may be further included. In FIG. 8, in addition to the population displayed in 3D, area information, time information, population change, sex ratio, etc. are displayed in 2D.

The three-dimensional visualization system and the three-dimensional visualization method using the same as described above are not limited to the configuration and method of the above-described embodiments, but the embodiments are all or part of each of the embodiments so that various modifications can be made. May be configured by selectively combining.

And it will be appreciated that various modifications and changes can be made to the present invention within a range not departing from the technical field.
