3 is a flowchart illustrating a process for performing a method for providing building sunshine time information according to another embodiment of the present invention.

First, a digital map is displayed by the display device 200 in step S300. The digital map includes indicators displaying real estate located on the map and various GUI objects for manipulating the digital map. Real estate located on the map may include multi-unit dwellings, particularly apartment complexes. On the digital map, a GUI object for obtaining a user's input requesting information on the hours of sunshine of a building of interest may be displayed. 4 shows a digital map including indicators 401 indicating real estate such as apartment complexes 500 and 600 is displayed in step S300.

In step S310, a user input for selecting a complex 500 for providing building sunshine time information among the complexes 500 and 600 located on the digital map is obtained. Referring to FIG. 4 , the user input may be an input for selecting one of the indicators 401 corresponding to the complexes 500 and 600 located on the digital map with a pointing device or a touch.

In step S320, a 3D model of the complex 500 to which building sunshine time information is provided is displayed. Step 320 will be described with reference to FIGS. 5 to 7 .

5 and 6 are diagrams illustrating an exemplary display of a 3D model of buildings of a complex 500 subject to providing sunshine time information. 5 is a view showing a state in which a 3D model of buildings of a complex 500 is observed from a first viewpoint, and FIG. 6 is a state in which a 3D model of buildings in a complex 500 is observed from a second viewpoint. is a drawing showing In the examples shown in FIGS. 5 and 6 , the complex 500 for providing the sunshine time information includes buildings 510 , 520 , 530 , 540 , 550 , and 560 .

In this embodiment, a user's input for changing the observation point of the 3D model of the buildings of the complex 500 subject to provision of sunshine time information may be acquired. The user input may be, for example, a click-and-drag or touch-and-drag input in an arbitrary direction within the area where the 3D model is displayed.

In some embodiments of the present invention, step S320 may be performed by rendering modeling data expressing the 3D shape of each of the buildings 510 to 560 belonging to the complex 500 in 3D. Modeling data expressing the 3D shape of each of the buildings 510 to 560 belonging to the housing complex 500 may be provided from, for example, the building information providing device 140 .

When a 3D model of the buildings 510 to 560 is rendered using modeling data, it is advantageous in that the actual shapes of the buildings 510 to 560 are accurately and precisely expressed. On the other hand, since the 3D modeling data of the buildings 510 to 560 is usually large, it consumes a lot of storage space and transmission bandwidth, and the processor throughput required for 3D rendering of the 3D modeling data is also high. Therefore, when the number of target buildings is large, such as when a service for displaying a 3D model is provided to all apartments nationwide, considerable hardware is required for storing, transmitting, and rendering 3D modeling data of all buildings. Resources may be required.

In some other embodiments of the present invention, the process of displaying the 3D model of the complex 500 for providing building sunshine time information relates to the shape of the outer wall of each of the buildings 510 to 560 belonging to the complex 500. It may be performed by estimating the 3D shape of each of the buildings 510 to 560 using only information and height information of each of the buildings 510 to 560 . The information on the shape of the exterior wall line and the altitude information may be provided from, for example, the building information providing device 140 .

The height information includes the height of the building, that is, the length from the ground to the top of the building and/or information on the number of floors of the building. If height information of at least one of the buildings 510 to 560 is unavailable, based on a value estimated based on the number of floors of the building (eg, a value obtained by multiplying the standard height between floors by the number of floors of the building), the height of the building height can be estimated.

7 shows the buildings 510 to 560 by using information about the shape of the outer wall line of each of the buildings 510 to 560 belonging to the complex 500 and the height information of each of the buildings 510 to 560. It is a diagram showing that the three-dimensional shape of can be estimated. Exterior wall lines 512, 522, 532, 542, 552, and 562 in FIG. 7 are lines indicating portions where outer wall surfaces constituting the respective buildings 510, 520, 530, 540, 550, and 560 come into contact with the site. If it is assumed that the planes of the buildings 510, 520, 530, 540, 550, and 560 are the same for each floor, the two-dimensional The shape corresponds to the plan shape of each building, and the elevations (514, 524, 534, 544, 554, 564) of each of the buildings (510, 520, 530, 540, 550, 560) correspond to the plan shape of the building. 3D models of each of the buildings 510 , 520 , 530 , 540 , 550 , and 560 belonging to the housing complex 500 may be estimated by constructing a three-dimensional shape by reflection.

Estimating a 3D model of a building using only the exterior wall line and elevation information of the building requires hardware resources required for data storage, transmission and rendering, compared to rendering the 3D model using the 3D modeling data of the building. It is advantageous in that it is relatively small. Therefore, when the number of target buildings is large, such as when a service for displaying a 3D model is to be provided to all apartments nationwide, or when a 3D model of a building needs to be displayed using a processor with relatively low processing performance. can have an advantage.

It will be described with reference to FIG. 3 again.

In step S320, displaying the 3D model of the complex 500 for providing building sunshine time information may include displaying a 3D model of buildings located around the complex 500 for providing building sunshine time information. .

Referring to FIGS. 9 and 10 , 3D models of buildings 610 , 620 , and 630 of the complex 600 surrounding the complex 500 to which sunshine time information is provided may be displayed. The display of the 3D model of the buildings 610 to 630 renders modeling data expressing the 3D shape of each of the buildings 610 to 630 in 3D, or the outer walls of each of the buildings 610 to 630. This may be performed by estimating the 3D shape of each of the buildings 610 to 630 using information about the shape of a line and height information of each of the buildings 610 to 630 . Modeling data of the buildings 610 to 630 or information on the shape of the outer wall line and the height of the buildings 610 to 630 may be provided, for example, from the building information providing device 140 .

In some embodiments, a three-dimensional model of the buildings 610 to 630 of the surrounding complex 600 may be displayed translucently, as shown in FIGS. 9 and 10 .

In addition to the buildings of the complex 500 to which the building sunshine time information is provided, the 3D shapes of the buildings of the neighboring complex 600 are also displayed, so that the shadows created by the buildings 610 to 630 of the neighboring complex 600 (thereby, This will be described later) can be intuitively recognized. In addition, since the 3D models of the buildings 610 to 630 of the surrounding complex 600 are displayed translucently, they will be visually differentiated from the 3D models of the buildings 510 to 560 of the complex 500, which is the main target of interest. and the 3D model of the buildings 510 to 560 of the complex 500 is not visually covered by the 3D models of the buildings 610 to 630 of the surrounding complex 600 even when the 3D models of the buildings 510 to 560 of the complex 500 are viewed at any observation point. can do.

It will be described with reference to FIG. 3 again.

In step S330, a user input for selecting a point of interest may be obtained. Here, the point of interest includes a time period of interest and a season of interest throughout the year. In order to allow the user to select a point of interest, a graphical user interface such as that shown in FIG. 8 may be provided.

FIG. 8 is a diagram illustrating an exemplary user interface for selecting a season and time zone for searching for information on a building's sunshine time. Referring to FIG. 8 , slider UIs 812 and 814 may be provided to select a time period of interest, and the time period of the day corresponding to each point of the movement track 812 of the sliding object 814 is labeled 816a, 816b, 816c). Also, referring to FIG. 8 , an interest season selection UI 820 may be provided. The user may designate a season of interest for searching for sunshine time information by selecting one of the objects 822 , 824 , 826 , and 828 corresponding to each of the four seasons.

In step S340, the sunlight condition of the time zone of interest may be visually displayed on the 3D model of the buildings 510 to 560 of the complex 500 for providing the sunshine time information selected in step S320.

In this embodiment, the visual display of the sunlight situation reflects the direction and altitude of the sun determined by the selected season and time at the location of each building 510 to 560 of the selected complex 500, This may include simulating and visually expressing sunlight irradiated on the 3D models of each of the buildings 510 to 560 . For example, on the surface of the 3D model of each of the buildings 510 to 560, a portion to which sunlight is irradiated may be expressed relatively brighter than a portion to which sunlight is not irradiated.

In this embodiment, the visual display of the sunshine situation simulates a shadow made by a part of the sunlight irradiated from the sun in the selected season and time period being blocked by each of the buildings 510 to 560, This may include projecting onto a dimensional model. For the simulation of the shadow, 3D graphic simulation techniques well known in the art may be used.

In this embodiment, the visual display of the sunshine situation simulates a shadow created by a part of the solar light irradiated from the sun in the selected season and time period being covered by features inside and outside the complex 500, It may include projecting onto a three-dimensional model.

In some embodiments, shadows created by topography such as hills and mountains located around the complex 500 may be simulated and projected onto the 3D model. At this time, information on topography such as hills and mountains located around the complex 500 may be acquired from, for example, the geographic information providing device 120 .

In some embodiments, shadows created by other buildings located around the complex 500 may be simulated and projected onto the 3D model. This will be described in more detail with reference to FIGS. 9 and 10 .

Other buildings located in the periphery of the complex 500 may include buildings of the complex or individual buildings located eastward, southward, or westward from the complex 500 . Other buildings located around the complex 500 may include buildings of the complex or individual buildings located northward from the complex 500 . However, in the case of the northern hemisphere, shadows created by buildings located in the northern direction from the complex 500 are not projected onto the buildings of the complex 500 . Therefore, shadows created by buildings located northward from the complex 500 do not affect the sunlight conditions of the buildings of the complex 500 . Therefore, in visualizing the sunshine situation of the complex 500, the shadows created by the buildings located in the east, south, or west of the complex 500 are simulated, but by the buildings located in the north of the complex 500 Not simulating the created shadow is advantageous for efficient use of computing resources.

In simulating the shadows of other buildings located around the complex 500, other buildings located around the complex 500 may be determined based on the distance away from the complex 500 and/or the height of the building. .

In some embodiments, other buildings located in the perimeter of the complex 500 may be limited to, for example, buildings whose elevation divided by their distance from the complex 500 is equal to or greater than a predetermined value. can This is because more shadows are projected into the complex 500 as the elevation of buildings around the complex 500 is higher and the distance away from the complex 500 is smaller.

In some other embodiments, the shadow of a distant building may not be simulated even if the building's height divided by the distance from the complex 500 is greater than or equal to a preset value. A distant building means a building whose distance to the complex 500 exceeds the reference distance. Even if the shadow of the distant building is actually projected inside the complex 500 because the altitude of the distant building is high, due to the influence of sunlight reflected from the surface of the feature that is closer to the complex 500, the distance of the distant building This is because the effect of the shadow on the complex 500 may be limited. Therefore, by not simulating shadows by distant buildings whose distance from the complex 500 exceeds the reference distance, but by simulating only shadows by nearby buildings whose distance from the complex 500 is within the reference distance, shadow simulation It is possible to efficiently utilize the computing resources required for

Simulating the shadows made by the buildings 610, 620, and 630 of the complex 600 around the complex 500, some of the solar light irradiated from the sun in the selected season and time period is reflected in each building 610 to 610. It may include simulating a shadow created by being covered by 630 and projecting it onto a 3D model of the buildings 510 to 560 of the complex 500 .

The simulation of the shadows of the buildings 610 to 630 is a shadow created by blocking some of the sunlight irradiated from the sun in the selected season and time by the three-dimensional shape of each of the buildings 610 to 630. including simulating. The three-dimensional shape of each of the buildings 610 to 630 can be identified from modeling data of each of the buildings 610 to 630 or estimated from the exterior wall line and elevation information of each of the buildings 610 to 630. . For the simulation of the shadow, 3D graphic simulation techniques well known in the art may be used.

9 and 10 show a complex 500 for providing sunshine time information, in which the effect of shadows created by buildings 610, 620, and 630 of the complex 600 around the complex 500 for providing sunshine time information is reflected. It is a drawing showing an exemplary appearance in which the sunlight situation is visually displayed. FIG. 9 shows an exemplary view of the shadows cast by the buildings 610 to 630 projected onto the three-dimensional model of the buildings of the complex 500 at 12:00 PM. FIG. 10 shows an exemplary view of the shadows cast by the buildings 610 to 630 projected onto the three-dimensional model of the buildings of the complex 500 at 14:00 PM. Referring to FIGS. 9 and 10 together, it can be understood that a state in which the solar situation of each location of the complex 500 is constantly changing according to the time zone can be displayed.

Meanwhile, in simulating the shadows created by the buildings 610 to 630 of the complex 600 around the complex 500 in step S340, the elevation difference between the complex 500 and the site of the complex 600 will be reflected. can More specifically, when simulating the shadows of the buildings 610 to 630, the heights of the buildings 610 to 630 are added to the heights of the sites 500 and 600 by adding the height difference between the sites. Differences may be reflected. This will be described with reference to FIG. 11 .

Referring to FIG. 11 , the heights of buildings 1120a and 1120b of FIG. 11 are the same. The building 1110 and the building 1120a are located on the same elevation. The building 1110 and the building 1120b are located on a site with a height difference (-d). As shown in FIG. 11 , the building 1120a projects a shadow up to a height L1 of the building 1110 . On the other hand, the building 1120b projects a shadow only up to the height of L2 of the building 1110 . That is, due to the elevation difference (-d) of the site where the buildings are located, the height or position at which the shadows projected by the buildings 1120a and 1120b of the same height affect the building 1110 is changed. Accordingly, in the shadow simulation in step S340, reflecting the difference in altitude between the site 500 and the surrounding complex 600 increases the accuracy of the simulation.

Meanwhile, in simulating the shadows created by the buildings 610 to 630 of the complex 600 around the complex 500 in step S340, the buildings 510 to 560 of the complex 500 and the complex 600 Altitude information of at least one of the buildings 610 to 630 may be input from the user, and a shadow may be simulated using the received information.

As described above, if information on the height or height of a building is unavailable, the height or height of a building estimated based on a number estimated based on the number of floors of the building (e.g., a value obtained by multiplying the standard height between floors by the number of floors of the building) can be used Using the estimated information in this way has the advantage of being able to provide a 3D model and/or shadow simulation of the building even when the height or height information of the building is incomplete, but some require an accurate 3D model or simulation. It may not meet the user's expectations.

Therefore, in some embodiments of the present invention, the user's expectation of a more accurate 3D model and shadow simulation is achieved by allowing the user to directly input the height information of the buildings and to simulate the shadow using the input information. level can be met. In addition, the building height information input from the user is recorded, the accuracy is verified by various verification methods well known in the art of the present invention, and the verified information is subsequently provided to other users in the 3D modeling or shadow of the corresponding building. It will be appreciated that it can also be applied to simulations.

In some embodiments, visually displaying the sunshine situation on the 3D model of the buildings 510 to 560 of the complex 500 for providing the sunshine time information in step S340 is the daily cumulative sunshine of each location in the complex 500. A color corresponding to time may be displayed at a corresponding position on the outer surface of the 3D model. Each location within the complex 500 may be, for example, each room within the complex 500 . Displaying the color corresponding to the cumulative daylight hours may include displaying a brighter color as the cumulative daylight hours is longer and a darker color as the daylight hours are shorter. FIG. 12 shows an example of a color corresponding to the cumulative daylight hours of the location displayed on the surface of the 3D model of the buildings 1210, 1220, 1230, 1240, 1250, and 1260 of the complex 500. has been shown In some embodiments, displaying a color corresponding to the cumulative hours of sunshine per day on the outer surface of the 3D model may be a continuous and gradual gradation of colors representing the hours of sunshine at each location, as shown in FIG. 12 . there is. In some other embodiments, displaying colors corresponding to cumulative hours of sunshine per day on the outer surface of the 3D model may be expressed in a visual graphic in the form of heat distribution, that is, in a heat map manner. In some other embodiments, displaying a color corresponding to the cumulative daylight hours of each room on the outer surface of the 3D model is a color corresponding to the cumulative daylight hours of each room with a color that is distinct from each other at a location corresponding to each room. it may be to indicate

In some other embodiments, visually displaying the sunshine situation on the 3D model of the buildings 510 to 560 of the complex 500 for providing the sunshine time information in step S340 is an accumulation of days at each location in the complex 500. A color corresponding to solar radiation may be displayed at a corresponding position on the outer surface of the 3D model. Regarding a specific method of displaying a color corresponding to the cumulative amount of sunlight per day at a corresponding location on the outer surface of the 3D model, the above description is made regarding the method of displaying the color corresponding to the cumulative amount of sunlight per day. can be referenced.

The daily cumulative solar radiation of each location within the complex 500 means the amount of solar radiation energy reaching each location during the day. The daily accumulated solar radiation at each location within the complex 500 shows a similar tendency to the daily accumulated solar time, but the daily accumulated solar radiation and the daily accumulated solar time are not exactly proportional. For example, a first location within the complex has a total of 6 hours of sunshine from 6:00 AM to 9:00 AM and from 3:00 PM to 6:00 PM, and a second location within the complex has hours of sunshine from 9:00 AM to 3:00 PM. Assume that there is a total of 6 hours of sunshine. In this case, the cumulative sunshine time per day at the first location and the second location is equal to 6 hours in total. However, since the amount of solar radiant energy reaching the ground per unit time is highest around 12:00 PM when the sun's altitude is highest, the daily accumulated solar radiation at the second location is higher than the daily accumulated solar radiation at the first location. As such, it will be understood that the cumulative daily sunshine time and the cumulative daily insolation amount are different pieces of information.

In some embodiments of the present invention, by displaying a color corresponding to the daily cumulative solar time and/or amount of solar radiation of each location within the complex 500 at a corresponding location on the outer surface of the 3D model, Concise and comprehensive information on solar conditions can be provided, and differences in solar conditions of each location within the complex 500, for example, each room, can be identified more clearly and easily.

It will be described with reference to FIG. 3 again.

In step S360, a gradual change in the sunlight situation according to a change in the time zone of interest may be displayed as an animation. For example, FIG. 9 shows an example of a shadow cast by the buildings 610 to 630 at 12:00 p.m. projected onto a 3D model of the buildings of the complex 500, and FIG. 10 shows a shadow at 14:00 p.m. represents an example projected on a 3D model. In response to the movement of the sliding object 814, a process of gradually changing from the image shown in FIG. 9 to the image shown in FIG. 10 may be displayed as an animation.

Referring to FIG. 15 , summary information 830 about the sunshine time zone of the location of interest 1400 may be provided. The summary information 830 includes the total amount of sunshine hours per day at the location of interest 1400 in the season of interest 828 and the maximum continuous sunshine hours at the location of interest 1400 . In addition, detailed information discriminating between a time period when sunlight reaches the position of interest 1400 and a time period when sunlight does not reach the position of interest 1400 may be provided.
