1A, 1B, and 1C are diagrams for comparison between the present invention and conventional city modeling. 1A is a conceptual diagram of a 3D object model digital twin according to the present invention. As shown, all facilities in the city including buildings and topography are objectified for city modeling, and data for each object is objectified as city center information. It can be implemented in two stages. In the object model-based digital twin, all implemented components, that is, individual elements, have data as one object, and through this, the digital twin model itself can analyze, predict, visualize, and control images and data. For example, simulation through visualization and analysis of building information and data is possible, and various controls in the city center such as buildings, facilities, equipment, traffic, atmospheric environment, and energy information through digital twins are possible.

The user terminal may include a personal PC-level computer including various input devices such as a touch screen, mouse, and keyboard, and the user can very easily query or process city center information displayed on the user terminal on a 3D model. In addition, since a lightweight 3D model can be displayed preferentially on the user terminal, and data for each object of the modeling (eg, large-capacity big data such as atmospheric environment, energy information, traffic information, etc.) is utilized as needed, the data It is possible that is input and calculated at high processing speed.

2 is a control block diagram of a 3D city modeling system according to an embodiment of the present invention. As shown, the 3D city modeling system according to the present embodiment includes a user terminal 100 and a modeling server 200, and the user terminal 100 and the modeling server 200 are connected through a wired or wireless network to exchange information with each other. can be exchanged. The user terminal 100 includes a communication unit 110 capable of communicating with the modeling server 200, a display unit 120 for displaying the modeled 3D city model, and selecting and enlarging a specific object included in the 3D city model. Alternatively, it may include a user manipulation unit 130 that can be reduced. The user terminal 100 may be implemented with various computing devices that may include the display unit 120, such as a personal PC, a portable phone, and a tablet PC.

The communication unit 110 may communicate with the modeling server 200 using one or more of various methods such as WLAN, Wi-Fi, WiBro, WiMAX, HSDPA, short-range wireless communication, infrared communication, UWB, or short-range wired communication. The display unit 120 displays a 3D city model and various graphic user interfaces, and any means capable of guiding information to the user, such as LCD, TFT-LCD, LED, OLED, AMOLED, flexible display, and 3D display, may be used. do. The user manipulation unit 130 may include one or more of various methods such as button input, touch input, motion input, and voice input.

The touch input senses a touch operation and generates a command, and includes a touch pad, a touch screen, and a touch sensor. Motion input recognizes a command corresponding to a predetermined specific motion, such as voice, pointer movement, or tilting or shaking the user terminal 100, and may be implemented with a microphone, mouse, camera, RGB sensor, or proximity sensor. A user may select, enlarge or reduce a specific object included in the 3D city model using the user manipulation unit 130 .

Meanwhile, the display unit 120 and the user control unit 130 may be independently configured, but when the user terminal 100 adopts a means capable of comprehensively performing input and output, such as a touch screen, they are integrated. It goes without saying that they can be combined. In addition, the user terminal 100 may further include a storage unit capable of storing object information provided from the modeling server 200 and a controller for controlling the illustrated components and input/output of data.

The modeling server 200 may include a control unit 210 , a database unit 220 and an object modeling unit 230 . In addition, the modeling server 200 may further include a communication unit (not shown) for communicating with the user terminal 100 and a processing unit for collecting data for city modeling. The database unit 220 stores modeling data such as digital topographic maps, cadastral maps, city image data, IoT information, and information collected through various routes, and includes atmospheric environment information that can be linked to objects, energy information, traffic information, Road guidance information, population information, building maintenance cost information, building power consumption information, and building deterioration information can be stored as big data.

In addition, GPS coordinates of the modeled object, ID of the object, etc. may be registered in the database unit 220, and all of these data may be updated in response to user manipulation and data change. The object modeling unit 230 classifies the modeling data stored in the database unit 220 into elements without a volume and elements with a volume, and performs 3D object modeling on the classified modeling data using a 3D modeling tool, Register the object by correcting the GPS coordinates of the modeled object.

The object modeling unit 230 according to the present embodiment loads data stored in the database unit 220, automatically objectifies the imported data, and uses a dynamic object-oriented script programming language to link data corresponding to the object. using ruby code. Ruby code is a pure object-oriented language, and treats all data types including integers and strings as objects, and corresponds to a computer information processing tool that automatically objectifies a city model in the present invention. According to this embodiment, since the lightweight DB access algorithm based on open source can be loaded through ruby code, the utilization of the data storage space of the digital twin itself can be increased.

In addition, the object modeling unit 230 expresses the surface of the object using a 3D modeling tool such as sketchup for the modeling data classified according to the presence or absence of the volume, gives properties to create a sense of volume, groups them into objects, and textures Do the work and calibrate the created elements. 3D object modeling using sketchup will be described in detail with reference to FIGS. 3 to 6 below. The control unit 210 may manage communication with the user terminal 100 and control the city modeling process performed by the object modeling unit 230, that is, data collection, data storage, data transmission, and the like. In addition, the control unit 210 according to the present embodiment transmits data linked to the selected object to the user terminal 100 in response to the object selection signal received from the user terminal 100 . The control unit 210 may be merged with the object modeling unit 230 to form a single module. 3 is a control flowchart for explaining a 3D city modeling method according to an embodiment of the present invention. First, the modeling server 200 may collect modeling data such as digital topographic maps, cadastral maps, city image data, and IOT information through various routes (310). Modeling data may be collected through cooperation with various government offices, institutions, etc., or may be dynamically and automatically collected through Internet networks and other communication lines. All of the data collected in this way may be stored in the database unit 220 and updated at regular intervals. For data collection, various conventional and currently utilized tools can be used.

The modeling data collected in this way is loaded into the object modeling unit 230 through ruby code, and the object modeling unit 230 can classify the modeling data into layers and elements and process them into basic data that can be used for modeling ( 320). Layer refers to a specific data group classified in the process of collecting various existing data and visualizing them in a model in order to express environmental information or energy information in a city model constituting a smart city. For example, when visualizing the flow of fine dust in a 3D city model, the visualized flow of fine dust can be regarded as one layer. An element means an individual composition that can be objectified in urban modeling. Processing of modeling data can be performed using various computer tools such as AutoCAD, and through this process, simple data is organized so that it can be implemented on a computer. Then, the object modeling unit 230 filters only essential data required for 3D object modeling from the processed basic data (330).

Filtering may be performed by determining whether the organized basic data includes data necessary for constructing a 3D city model. As a result of the determination, only elements including necessary data are used for modeling, and data for elements that do not include may be deleted. Then, the object modeling unit 230 performs a trimming operation on the filtered modeling data, classifies the modeling data into elements without a volume and elements with a volume, and models the classified modeling data using a 3D modeling tool. Do (340). 3D object modeling is done using 3D modeling tools such as SketchUp, and SketchUp carries out the three-dimensional work for the digital twin by separately importing volumetric elements and non-volume elements. Hereinafter, referring to FIGS. 4 and 5, 3D object modeling of elements according to the presence or absence of a volume will be described. 4 is a control flow diagram for explaining an object modeling method according to an embodiment of the present invention, and FIG. 4 illustrates 3D object modeling for a volumeless element.

First, the non-volume element is input to a modeling tool such as SketchUp, and SketchUp creates a surface on the non-volume element (410). Elements without volume refer to elements that do not have volume, such as topography and roads, and may correspond to elements that are the most basic for city modeling. When the surfaces of the terrain and the road are created in this way, the object modeling unit 230 groups the elements from which the surfaces are created to shape the object (420). The elements on which the surface is formed can be grouped into terrain such as land, roads with cars, sidewalks, etc., and can be grouped by various categories depending on the characteristics of the terrain in detail, such as asphalt or unpaved roads. When object shaping of one element is in progress, it may be determined whether there are additional elements requiring object shaping (430). As a result of the determination, if there is an additional element that requires object shaping, the volumeless element may be input into a 3D object modeling tool, grouped, and object shaped. On the other hand, there are no additional elements, and SketchUp proceeds with texture work on the created object (440). That is, the object modeling unit 230 may perform a material mapping process of adding and supplementing materials to non-volume elements so that the digital twin visually looks more similar to reality.

5 is a control flowchart for explaining an object modeling method according to another embodiment of the present invention, and FIG. 5 illustrates 3D object modeling for a volumetric element. Similar to step 410, the volumetric element that has been filtered is input to a modeling tool such as SketchUp, and SketchUp creates a surface on the volumetric element (510). After that, SketchUp gives attribute data such as height and area to the non-volume element to shape it, and modifies and optimizes the shape of the element to which the attribute information is assigned (520). Unlike elements without volume, elements with a sense of volume and volume must be shaped in size, and correction of the shape is required. Attribute data and data necessary for correction between a plurality of shaped elements are also stored in the database unit 220 . The optimally shaped element is determined whether or not its shape is within a predetermined tolerance range (530). To this end, attribute information is assigned, an error between the shape of the modified element and the actual element is calculated, and whether the error value is within an acceptable error range may be determined.

As a result of the determination, if the error between the shaped element and the actual element is out of the allowable range, step 520 is entered again, and the process of modifying and optimizing the shape is repeated. On the other hand, if the error between the shaped element and the actual element is within the allowable range, SketchUp may form an object by grouping the volumetric elements (540). Elements may be grouped according to shapes and functions, such as buildings, traffic lights, street trees, housing complexes, factory complexes, etc. arranged on a road, and object shaping is performed in response to attribute information. When object shaping of one element is in progress, it may be determined whether there are additional elements that require object shaping (550).

As a result of the determination, if there are additional elements that require object shaping, the voluminous elements can be input into the 3D object modeling tool, grouped, and object shaping. A texture operation is performed to add and supplement materials to elements with a volume so as to look good (560). Referring back to FIG. 3 , when 3D object modeling is performed on an element, an object registration process proceeds thereafter. The object modeling unit 230 registers the object in the database unit 220 by correcting the GPS coordinates of the modeled object (350). A process for this will be described with reference to FIG. 6 which is a control flow diagram for explaining the object registration method according to the present embodiment.

Objectized elements may be displayed on the display unit 120 of the user terminal 100, and as shown in FIG. is extracted and converted into actual GPS coordinates (610). Internal coordinates are one piece of location information for specifying an object displayed on the display unit 120, and through this, mutual positions between displayed objects can be grasped. Since the existing GIS internal coordinates are coordinates in the form of a 2D plane, in order to model with 3D stereoscopic information, it is necessary to identify the location and shape of an object by specifying the 3D internal coordinates based on GIS-BIM.

The converted GPS coordinates are corrected through actual GPS coordinates and satellite information (620), and the object modeling unit 230 determines whether the corrected GPS coordinates exist within a predetermined tolerance range (630). That is, correction Accuracy of correction can be judged by calculating the error range between the calculated coordinates and the actual coordinates and setting the allowable range.

If the corrected GPS coordinates are out of the predetermined tolerance range, the GPS coordinates go through the correction process of step 620 again. As a result of the panda, if the error between the corrected GPS coordinates and the actual GPS coordinates is within the allowable range, it may be determined whether the corrected GPS coordinates of the object are stored in the database unit 220 (640). This is to prevent duplicate registration by checking whether an object is already registered, and to newly update only a new object.

As a result of the determination, if the coordinates of the object are stored in the database unit 220, the additional registration process is omitted, and if not stored in the database unit 220, the object modeling unit 230 assigns a new ID to the object and Register at (220) (650). The newly registered object is transmitted to the user terminal 100 together with the ID (660), and the object ID may be stored in the user terminal 100.

In this way, newly 3D objectified elements can be displayed on the user terminal 100 , and the user can reduce or enlarge the city modeling screen using the user control unit 130 and select a specific object. As in step 360 of FIG. 3 , the controller 210 may transmit data linked to the selected object to the user terminal 100 in response to the object selection signal received from the user terminal 100 . The detailed data linked to the object includes at least one of atmospheric environment information, energy information, traffic information, road guidance information, population information, information on building maintenance costs, information on power consumption of buildings, and information on deterioration of buildings. can include In this way, since detailed information on an object can be provided to and utilized by the user only when necessary, it is possible to reduce the weight of city modeling and speedy information processing.

Since the city modeling system according to the present invention is a digital twin-based integrated information processing system that is suitable for smart cities and implements city services, it is possible to expand, apply, and apply services in various fields. That is, it is possible to connect the real space and the virtual space to informationize the real situation in the virtual space, and provide user-centered intelligent services to utilize it. For example, the flow of air environment such as fine dust or odor can be visualized in the form of a layer on the digital twin model, and the maintenance cost of the building can be predicted, or the predicted usage can be calculated using the calculated power usage. It can be compared, and facility maintenance based on a dimensional object model, such as a building deterioration simulation, is possible. 7 is a diagram illustrating an example of utilization of city modeling according to an embodiment of the present invention.

7 shows various examples of evacuation routes when a disaster situation occurs. In addition, through city modeling, it is possible to simulate a pre-response system and provision of evacuation information when a disaster situation occurs. As described above, the present invention is a computer information processing program that automatically objectifies a city model by inputting city information and importing it into ruby code. to be In addition, it is about a city modeling system and modeling method that converges various technologies and links IoT sensor technology rather than using limited topographical or building information. integrated management becomes possible.
