Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present disclosure rather unclear.

1 is a control block diagram of a system for 3D modeling according to an embodiment of the present invention.

As described above, due to the interest in smart city and the increase of users who want to use it, much attention has been focused on implementation of 3D modeling of cities based on IOT (Internet of Things). A system including a terminal and a server according to the present invention provides various user interfaces for enhancing user familiarity and accessibility in 3D modeling implementation. To this end, the system 1 according to the present embodiment includes a terminal 100, a BIM (Building Information Modeling) information and / or BIM data, a GIS (Geographic Information System) information, and / or a GIS data And a server 200 for providing the service.

The spatial information for 3D modeling can be largely divided into indoor spatial information and outdoor spatial information, and indoor spatial information can be generally represented by BIM data, and outdoor spatial information can be represented by GIS data.

BIM refers to the process of modeling a facility in a multi-dimensional virtual space such as planning, design, engineering (structure, facility, electricity, etc.), construction, further maintenance and disposal. In particular, it is a similar concept to the Virtua Design Construction (VDC), which enables the design and construction of cutting edge design and eco-friendly low-cost buildings.

BIM can digitize buildings to produce numerical data, and can display 3D display effects. Data of a length connecting the start and end points of the line, rather than a simple line or plane operation, is generated, and the area is digitized with reference to the closed plane.

GIS is a computer system that collects and makes available the hardware, software, and geographical data of computers designed to collect, store, update, adjust, analyze and represent all types of geographically referential information effectively.

GIS is a system for storing, extracting, managing, and analyzing information by linking geographical information that represents a spatial location for various earth surface information references, and non-graphic attribute information that explains and complements its form and function with graphical and database management functions. It is also a comprehensive analysis tool that expresses the spatial relationship of map by adding feature (attribute) information of terrain information. Geographic data occupying spatial position and related attribute data are integrated and processed. GIS can be widely used in land information management, facility management, transportation, urban planning and management, environment, weather forecasting, agriculture, disaster and disaster, education and population prediction.

The BIM data used in the present specification may refer to all information about a building used for implementing a BIM such as a road, a bridge, and a structure. In addition to the geographical information such as a typical river, a park, Parking facilities, IOT (internet of things) facilities for measuring air pollution, CCTV, and the like.

The terminal 100 includes a user interface unit 110, a communication unit 120 and a 3D modeling unit 130. The terminal 100 is easy to access to a user, such as a portable telephone, a personal computer, a tablet computer, It can be implemented in one electronic device.

The server 200 may include a storage unit 210 and a control unit 220 and may be implemented as a computer capable of exchanging various information through communication with the terminal 100. [

The user interface unit 110 according to the present embodiment provides the user with various graphic interfaces to receive user settings for 3D modeling implementation. Through the graphical interface, the user can input various conditions for the 3D modeling, thereby enabling 3D modeling that meets the user's desired conditions.

That is, according to the present invention, 3D modeling can be performed in various forms according to the preference or the situation of the user rather than the conventional collective and stereoscopic 3D modeling. For example, even if the 3D modeling is performed for the entire city, 3D modeling can be implemented using specific information, for example, the appearance of the building, the outline or the outline of the road, thereby reducing the amount of data and realizing simplified 3D modeling.

Details of the user settings and the user interface are described in detail below.

The communication unit 120 transmits information on user settings to the server 200 while communicating with the server 200 and receives BIM data and GIS data corresponding to user settings from the server 200. [ The communication unit 120 may be implemented as a communication interface capable of wired / wireless communication.

The 3D modeling unit 130 performs 3D modeling based on the BIM data and the GIS data. The 3D modeling unit 130 may be implemented by various models, applications, programs, or the like that perform 3D modeling based on the object information. For example, the 3D modeling unit 130 can generate and share a 3D model similar to Google sketch-up or Google sketch-up, in which a user can directly create a 3D space model in Google Earth, It can be implemented in applications such as Googlebuilding maker that can be combined with satellite maps. However, it is obvious that the 3D modeling unit 130 is not limited to the Google sketch up or Google building maker described above, but can be implemented by various modeling tools that typically implement 3D modeling.

The storage unit 210 of the server 200 stores the BIM data and the GIS data.

The controller 220 may provide the terminal 100 with BIM data and GIS data corresponding to the user setting among the BIM data and the GIS data stored in the storage unit 210. [ That is, the control unit 220 provides only the minimum amount of data corresponding to the user setting among the large amount of BIM data and GIS data stored in the storage unit 210 to the terminal 100. [ This enables 3D modeling for the entire city, while greatly reducing data volume, enabling faster and more immediate 3D modeling as well as saving resources.

In addition, according to the present invention, the storage unit 210 may store user setting contents as data under the control of the controller 220. [ Such user information can be utilized in various aspects. For example, before introducing the operation of the actual Smart City, it is possible to measure various aspects of the user's characteristics, daily life, viewpoints, or perceptions and accumulate prior information therefrom. The accumulated information can also be used as data to verify whether the IOT sensors installed in the building are operating properly.

The control unit 220 may include a communication module (not shown) for communicating with the communication unit 120 of the terminal 100.

2 is a photograph of a 3D modeled city in accordance with an embodiment of the present invention.

Specifically, FIG. 2 is a 3D modeling of 820 buildings and about 50 km on the periphery of the campus of the University of Seoul. The data on the shape of the building, the location coordinates of the center line, and the height of the BIM data and the geometrical information , And soil quality were used.

The 3D modeling as shown in FIG. 2 can be utilized for analysis and review of the traffic system around the University of Seoul, and can be applied to road operation and road utilization by linking IOT sensors. That is, FIG. 2 corresponds to an example of a smart-city user interface using the IOT. For 3D modeling in FIG. 2, BIM data and GIS data are integrated and implemented, and object-oriented modeling is performed based on the ISO 10303 "STEP" technology, which is an international standard data format.

In summary, according to the present invention, buildings, roads, bridges, and the like are expressed as objects in 3D, and information through an IOT sensor existing in the objects is automatically connected to combine current real situation data with smart city 3D modeling . By applying this 3D modeling to hundreds of smart cities that have been extensively researched and developed at home and abroad, users will be able to grasp the results of smart city modeling, and predict future trends and problems based on the current situation.

3 and 4 are views showing a user interface window according to an embodiment of the present invention.

As described above, according to the present invention, the user can receive various graphic interfaces through the user interface unit 110 of the terminal 100, and can set various options or symbols for 3D modeling have.

For example, the user may be provided with a graphical interface window (I) as shown in FIG. 3 to set a situation for a specific situation, a BIM data setting for selecting at least one individual BIM data among the BIM data, A GIS data setting for selecting one individual GIS data, and a data size setting for limiting the size of BIM data and GIS data to be received from the server.

Situation setting for a specific situation is for a special situation in which 3D modeling is required. If the user selects the graphical interface window I of FIG. 3, the sub-graphical interface window II shown in FIG. 4 may be provided. As shown in FIG. 4, the user can select at least one of a CCTV status, a road traffic light display status, and a building selection status that defines a specific building as a situation setting, for example.

When the user selects the CCTV situation, the user can directly view the desired CCTV screen on the terminal 100 after 3D modeling for a specific area. Through this direct access, the user can view the CCTV screen, which was only seen in the existing control room or the control room, at any time and any time.

Alternatively, the user can determine the direction of travel by selecting the display state of the road signal or the like, and can also determine whether the entire road signal lamp is defective or not. It is also possible to receive the information of the terminal about the road condition attached to the road signal lamp. For example, the traffic volume of a specific road or the number of pedestrians can be grasped. Intelligent CCTV can be used to determine the traffic volume or the number of pedestrians. Conventionally, only high-resolution (4K), ultra-low-light camera or the like is used to display images taken by a camera. However, in the present invention, the demand and type of a traffic vehicle can be automatically detected using a real-time image. You can set a specific area to count the number of pedestrians passing through a particular area, counting the passage of vehicles, vehicles, forward or reverse traffic passing through that area.

In addition, the user may perform 3D modeling by selecting only a specific building, for example, a specific building such as a fire station or a hospital, as an object. In this case, since only the terrain information of the building desired by the user is required for the 3D modeling, the user can view the 3D modeled city more quickly.

Alternatively, the user may select at least one individual BIM data among the vast BIM data stored in the server 200, or may select at least one individual GIS data among the GIS data. For example, a user can perform 3D modeling by selecting only the outline form of a building with individual BIM data or only a specific terrain or road such as an acid or a river with individual GIS data.

In addition, the user can limit the amount of data transmitted from the server 200 while performing 3D modeling as before. When the data size setting is requested from the terminal 100, the server 200 may transmit only the minimum data for graphicization among the BIM data and the GIS data, or may provide only the main data to the terminal 100.

Through such user setting, a large amount of data can be reduced from the data required for 3D modeling, so that the speed of communication increases and the user can see the desired 3D modeling result more quickly.

Meanwhile, according to another embodiment of the present invention, the 3D modeling unit 130 may model a specific building or road with a specific color according to predetermined color information. For example, depending on the user's selection or preset, the fire station may highlight red, hospitals white, or certain distances in frequently visited areas.

That is, the 3D modeling unit 130 may model a specific object in a specific color according to predetermined color information. This also corresponds to one aspect of the provision of the user interface, which can increase the user's experience index.

The graphical interface windows (I and II) provided to the user are not limited to those shown in FIGS. 3 and 4, and thus the user settings that the user can select for 3D modeling are not limited to those described above. These user settings can be accumulated and updated as data.

When the user sets various situations or options as in the above-described example, the control unit 220 of the server 200 may store the user settings in the storage unit 210 as a database. When such a database is stored, the server 200 can categorize the BIM data and the GIS data necessary for 3D modeling and can provide the data corresponding to the user request more aggressively and promptly.

5 is a control flowchart for explaining a 3D modeling method according to an embodiment of the present invention. A 3D modeling method of a system including a terminal and a server storing BIM data and GIS data will be described with reference to FIG.

First, the user can input user settings for 3D modeling implementation in the terminal (S10). This can be implemented through a graphical interface window provided through the user interface unit of the terminal.

The user setting includes setting a situation for a specific situation, BIM data setting for selecting at least one individual BIM data among BIM data, GIS data setting for selecting at least one individual GIS data among GIS data, BIM data and GIS And a data size setting that defines the size of the data.

Further, the situation setting may include at least one of a CCTV situation, a road traffic light indication situation, and a building selection situation that defines a specific building.

When the user inputs the user setting, the terminal can request the server to provide the BIM data and the GIS data corresponding to the user setting (S20).

The server receiving the user setting can provide only the BIM data and GIS data corresponding to the user setting among the stored BIM data and GIS data to the terminal (S30).

Then, the 3D modeling unit of the terminal can perform 3D modeling based on the received BIM data and GIS data (S40).

At this time, the 3D modeling unit may model the specific color of the specific building or road according to the predetermined color information, or more generally, the specific color of the specific object according to predetermined color information.

6 is a control flowchart for explaining a 3D modeling method according to another embodiment of the present invention.

According to the present embodiment, the server receiving the information on the user setting can transmit an alarm related to the emergency situation to the external organization when the data corresponding to the user setting satisfies the preset condition for the emergency situation.

As shown in the figure, according to the present embodiment, the user setting is received for 3D modeling (S10), the user setting is transmitted to the server (S20), and the BIM data and GIS data When the data is transmitted to the terminal (S30), the 3D modeling based on the BIM data and the GIS data in the terminal (S40) is substantially the same as that in Fig.

The server that has grasped the BIM data and the GIS data corresponding to the user setting can determine whether or not such data satisfies predetermined conditions for the emergency situation (S50).

As a result of the determination, if the BIM data and the GIS data satisfy predetermined conditions for the emergency situation, the server can transmit an alarm related to the emergency situation to the external organization (S60).

External organizations may be police stations, fire stations, emergency rooms in hospitals, and so on. Based on the accumulated database, if the user is determined to be in an emergency or a fire has occurred, the server may notify the relevant authorities of such information.

In addition, the server can transmit to the terminal information indicating that the alarm has been transmitted to the external organization (S70). The user can know that his or her situation has been delivered to the institution through the information received from the server. If the user is not in an emergency situation, the user may inform the external organization again that the alarm by the server is erroneous.

On the other hand, when the BIM data and the GIS data do not satisfy predetermined conditions for the emergency situation, the server does not transmit an additional alarm signal to the external organization.

According to another embodiment of the present invention, the 3D modeling unit may be realized in a server rather than a terminal. That is, the server may perform 3D modeling based on the BIM data and the GIS data corresponding to the user setting, and then transmit the 3D modeling to the terminal.

As described above, the present invention provides a terminal, a server, a system including the same, and a 3D object modeling method for implementing 3D modeling that provides a user interface according to various situations, thereby enhancing the usability of a smart city by enhancing user accessibility .

In the above-described embodiments, the methods are described on the basis of a flowchart as a series of steps or blocks, but the present invention is not limited to the order of steps, and some steps may occur in different orders or in a different order than the steps described above have. It will also be understood by those skilled in the art that the steps depicted in the flowchart illustrations are not exclusive and that other steps may be included or that one or more steps in the flowchart may be deleted without affecting the scope of the invention You will understand.

The above-described embodiments include examples of various aspects. While it is not possible to describe every possible combination for expressing various aspects, one of ordinary skill in the art will recognize that other combinations are possible.
