Description

Technical Field

[0001] The present invention relates to a technology for providing a three-dimensional relief map.

Background Art

[0002] The recent increase in the number of tourists is remarkable, and along with this, the content provided to tourists is also increasing. As conventional tourism information content, a tourist map that displays the locations of tourist attractions, restaurants, accommodation facilities, etc. is usually provided. However, since such a tourist map only displays simple information, there is a possibility that tourists may be more or less restricted in reaching their destinations only with the map.

[0003] The tourist map has a very important function of compressing all aspects of tourism so that one can touch its culture at a glance. Since it conveys tourist information, transportation, history, culture, etc. all at once, improvement in this regard has been constantly desired. The types of tourist maps that have been mainly used so far can be roughly classified into a general map application type, a transportation / tourism mixed type, and a three-dimensional pictorial map type.

[0004] The general map application type adheres to the notation format of general maps, but is edited into a simple form focusing on information about tourist destinations. It has the advantage of being easy to produce, but it lacks aesthetic appeal and is therefore unable to fully fulfill its role in conveying an image or promoting tourism. The mixed transportation / tourism type is produced using the national base map as a base, displaying roads and areas, and inserting illustrations and photographs of major tourist destinations. While it can enhance the aesthetic effect of conveying information about tourist destinations, it still suffers from visual complexity because it uses the road system of the base map as is. The three-dimensional pictorial map type is produced in three dimensions using perspective projection. Although it has difficulty in accurately conveying location and geographical information, it offers the advantage of being able to show the characteristics of tourist destinations in three dimensions. Conventional tourist maps of this type are produced based on the road system of a basic map, with only visual effects added to the tourist destinations. The surrounding mountains are depicted using contour lines or a uniform pattern along the north-south direction. As a result, they do not match the visual perception of tourist destinations within local government units at the county level in Korea (roughly equivalent to counties in Japan) while actually driving, and are therefore inconvenient to use.

[0005] While existing maps play a crucial role in compressing all information and allowing us to experience a culture at a glance, their limitations in conveying images and providing spatial information remain a concern. In particular, the mountainous terrain of South Korea clearly demonstrates the limitations of flat maps, highlighting the need for three-dimensional maps to enhance visibility and information transmission.

[0020] FIG. 1 is a diagram schematically showing the configuration of a three-dimensional stereoscopic map providing system according to the first embodiment of the present invention.

[0021] Referring to FIG. 1, the three-dimensional stereoscopic map providing system according to the first embodiment of the present invention includes a server 100 and a user terminal 200.

[0022] The user terminal 200 is a terminal capable of communication via a wireless communication network and can be implemented using a wide variety of devices such as mobile phones, smartphones, and tablet PCs.

[0023] In this invention, the user terminal 200 can download and install a dedicated application from the server.

[0024] Server 100 communicates with user terminal 200 via a wireless communication network, generates a three-dimensional map by combining spatial information and location information for each region, and provides the three-dimensional map to user terminal 200 via a dedicated application.

[0025] Server 100 can display a three-dimensional map with different color tones depending on the geological structure.

[0026] When generating a three-dimensional map, server 100 can display it with different color tones depending on the altitude.

[0027] Server 100 can display relevant information, including public institutions, schools, tourist attractions, ports, airports, and walking routes, on a three-dimensional map.

[0028] In the present invention, the 3D map provision system can provide group management functions to user terminals that have registered a group with a predetermined group name via a dedicated application.

[0029] Figure 2 is a schematic diagram showing the configuration of a three-dimensional map provisioning system according to a second embodiment of the present invention. Figure 2 illustrates the provision of a group management function in the three-dimensional map provisioning system according to the second embodiment of the present invention.

[0030] Referring to Figure 2, the server 100 can provide group management functionality to user terminals 310, 410, and 420 that have registered for group 10 via a dedicated application. When registering a group, one or more user terminals can be registered as the administrator terminal 310, and the remaining user terminals can be registered as group member terminals 410 and 420. The server 100 can provide group management functionality to the administrator terminal 310 and the group member terminals 410 and 420, each containing different functions, via a dedicated application.

[0031] Figure 3 is a flowchart showing the process for determining hazardous areas in a 3D map provision system according to one embodiment of the present invention, and Figure 4 is a diagram illustrating the types of hazardous information according to one embodiment of the present invention.

[0032] Referring to Figures 3 and 4, the server 100 generates a draft of a three-dimensional map (S101) and collects two or more types of hazard information (S103). In one embodiment of the present invention, the server 100 can collect hazard information such as geographic hazard information, seasonal (time) hazard information, warning information, meteorological hazard information, and traffic hazard information. In this case, the server 100 can collect hazard information via servers of relevant public institutions and information providers. For example, meteorological hazard information can be collected via the Japan Meteorological Agency server, and traffic hazard information can be collected via the National Police Agency server.

[0033] In Figure 4, examples of geographic hazards include cliffs, rockfall areas, ponds, coastlines, and riverbanks; seasonal hazards include flood season and avalanche season; warnings include rainfall, snowfall, rapid currents, dangerous individuals, dangerous animals, hazardous material discharge, pests, and diseases such as foot-and-mouth disease; meteorological hazards include volcanoes, earthquakes, tsunamis, heat waves, heavy snow, heavy rain, and extreme cold; and traffic hazards include congestion, closures, and detours.

[0034] If server 100 has collected two or more types of hazard information (S105), it determines that the area is a hazardous area (S107). For example, if there is information on cliffs and rainfall for the area, it determines that the area is a hazardous area.

[0035] The server 100 then displays the hazardous area on the draft of the 3D map to complete the 3D map (S109). Then, it transmits the 3D map to the user terminal 200 (S111).

[0036] Figure 5 is a flowchart showing a specific method for the group management function in a 3D map provisioning system according to one embodiment of the present invention.

[0037] Referring to Figure 5, the server 100 provides the administrator terminal 310 with a function that allows setting regions of interest and restricted areas on a three-dimensional map via a dedicated application. In this case, the server 100 can provide a function that allows input by freely drawing lines on the three-dimensional map when setting regions of interest and restricted areas, and using this function, closed curves input from the administrator terminal 310 can be set as regions of interest and restricted areas. In one embodiment of the present invention, the server 100 can restrict restricted areas to be set within regions of interest.

[0038] When the administrator terminal 310 sets the region of interest and restricted areas (S201), the server 100 generates a simplified feature map showing the main points around the region of interest (S203).

[0039] Server 100 generates a detailed location map from the feature map, which is a map displaying detailed information about each location (S205).

[0040] Server 100 transmits information on areas of interest and restricted areas, as well as feature maps and location detail maps, to the administrator terminal 310 and group member terminals 410 and 420 (S207).

[0041] Server 100 provides each terminal 310, 410, and 420 with a three-dimensional map showing areas of interest and restricted areas, and displays the current location of each terminal 310, 410, and 420 on the map (S209).

[0042] Server 100 checks the location of each terminal 310, 410, and 420 in real time. If any of the terminals 310, 410, or 420 leaves the area of ​​interest or enters a restricted area (S211), it transmits a warning message to the terminal and a notification message to the administrator terminal 310 (S213).

[0043] Figure 6 is an illustrative diagram illustrating the setting of regions in a three-dimensional map provisioning system according to one embodiment of the present invention.

[0044] Figure 6 illustrates a three-dimensional map of Jeju Island, South Korea, displayed on a terminal, and it can be seen that an area of ​​interest 610 and a restricted area 620 are set on the map. Here, the restricted area 620 is set centered on Mount Hallasan and Baeknokdam.

[0045] By inputting a closed curve onto a three-dimensional map from a dedicated application via an input unit on the administrator terminal 310, the region of interest 610 and the restricted area 620 can be set. In this case, if the input unit is a separate touchpad, the closed curve can be input using a stylus pen or the like on the touchpad, and if the input unit is a touchscreen, the closed curve can be input using a finger or the like. For example, if there is an area that needs to be restricted, such as a lake, within the accessible region of interest, the restricted area 620 can be set inside the region of interest 610.

[0046] In Figure 6, the server provides a "feature diagram" icon 630 on a portion of the screen. If the "feature diagram" icon 630 is selected, the server provides a simplified feature diagram focusing on the main points of interest in the region of interest 610.

[0047] Figure 7 illustrates a feature diagram of a 3D map provisioning system according to one embodiment of the present invention.

[0048] The feature diagram in Figure 7 is an example of a feature diagram relating to the region of interest 610 shown in Figure 6, with Jeju Airport 710, Seongpanak Rest Area 720, Seogwipo Recreation Forest 730, and Equestrian Park 740 being exemplified as main locations and displayed as simple icons or blocks. If a main location is selected from the feature diagram, the server 100 provides a location detail map, which is a map displaying detailed information about the selected main location.

[0049] Figure 8 is an example of a location detail map in a 3D map provision system according to one embodiment of the present invention. The location detail map illustrated in Figure 8 is an example of a location detail map relating to Jeju Airport 710 in Figure 7. Thus, the present invention provides an interface that allows quick and easy movement from the 3D map screen to a specific area using a feature map showing the main locations and a location detail map showing detailed information about the main locations.

[0050] Figure 9 is an illustrative diagram illustrating the process of confirming the location of a terminal and determining whether or not it has left the area, in a three-dimensional map provisioning system according to one embodiment of the present invention.

[0051] Referring to Figure 9, the group member terminals 410 and 420 can transfer location information to the server 100 via a base station 910 that is linked to the server 100. The server 100 then receives the location information determined by the group member terminals 410 and 420 from the base station 910 and can determine whether the group member terminals 410 and 420 have left the area of ​​interest 610 or entered the restricted area 620.

[0052] The group member terminals 410 and 420 can determine their location using at least one of the following positioning methods: GPS positioning, Wi-Fi positioning, and CELL positioning. In this case, the positioning method can be adaptively changed according to the external environment in which the terminal is located, and the location can be determined using the changed method.

[0053] The server 100 can then transfer the determination results related to the area of ​​interest 610, which it has determined based on the location information of the group member terminals 410 and 420, to the administrator terminal 310. Specifically, the server 100 can determine whether or not the group member terminals 410 and 420 are present in the area of ​​interest 610, which has been set based on the location information of the group member terminals 410 and 420.

[0054] Based on the determination result regarding whether the group member terminals 410 and 420 are present in the area of ​​interest 610, the server 100 can forward to the administrator terminal 310 whether they have left the area of ​​interest 610 or entered the restricted area 620.

[0055] Server 100 can determine whether group member terminals 410 and 420 are located in the area of ​​interest 610. In other words, server 100 can determine that group member terminals 410 and 420 are located within the area of ​​interest 610 based on their location information. Server 100 can then forward this result—that the terminals are located within the area of ​​interest 610—to administrator terminal 310.

[0056] Server 100 can determine whether group member terminals 410 and 420 have left the area of ​​interest 610. In other words, group member terminals 410 and 420 may have moved to a location outside the area of ​​interest 610. Server 100 can re-receive location information at the location where group member terminals 410 and 420 have moved. Based on the re-received location information of group member terminals 410 and 420, Server 100 can determine that group member terminals 410 and 420 have left the area of ​​interest 610 and transfer the result of this determination to administrator terminal 310.

[0057] Next, the administrator terminal 310 can take prompt action depending on whether the group member terminals 410 and 420 have left the area of ​​interest 610 by triggering sensors on the group member terminals 410 and 420, making phone calls, or forwarding messages.

[0058] Furthermore, server 100 logs the locations where group member terminals 410 and 420 have left the network, and this information can be used in the future to reset the secure area based on the logged locations.

[0059] Server 100 can determine whether group member terminals 410 and 420 have entered the restricted area 620. In other words, based on the received location information, server 100 can determine that group member terminals 410 and 420 have entered the restricted area 620 and forward the determination result to administrator terminal 310.

[0060] In short, the server 100 can provide information that allows administrators to quickly become aware of sudden situations involving group members by determining whether or not they are within an area set by the terminals based on location information obtained from the group member terminals 410 and 420.

[0061] At this time, the group member terminals 410 and 420 and the administrator terminal 310 may have completed the authentication process for receiving location information from the group member terminals 410 and 420 based on the communication service. In other words, the group member terminals 410 and 420 can register as administrators with the administrator terminal 310 for managing the location of the group member terminals 410 and 420. The administrator terminal 310 can then link with the group member terminals 410 and 420 by performing administrator authentication for the registered group member terminals 410 and 420. Subsequently, the administrator terminal 310 can receive location information determined from the group member terminals 410 and 420.

[0062] The group member terminals 410 and 420 can register as administrators with the administrator terminal 310, which can then check the location of the group member terminals 410 and 420. Here, administrator registration may mean registration of the administrator terminal 310, which can receive location information from the group member terminals 410 and 420. In other words, administrator registration may mean an application to grant the administrator terminal 310 the right to use functions that allow it to manage the group member terminals 410 and 420.

[0063] Next, the administrator terminal 310 can perform administrator authentication for group member terminals 410 and 420 that have completed administrator registration, using a dedicated application capable of managing the functions of the group member terminals 410 and 420. Here, administrator authentication may mean acceptance of the administrator registration made on the group member terminals 410 and 420. In other words, administrator authentication may mean acceptance of the administrator registration requested by the group member terminals 410 and 420 in order to manage functions related to the group member terminals 410 and 420, such as telephone, messaging, location confirmation, schedule confirmation, activity levels, and environmental settings of the group member terminals 410 and 420.

[0064] Specifically, the administrator terminal 310 can perform administrator authentication based on unique identification information assigned to the administrator terminal 310 after accepting consent to use the management terms and conditions for the group member terminals 410 and 420 using a dedicated application. Here, the administrator terminal 310 can perform administrator authentication in accordance with the identification information of the administrator terminal 310 that has been registered as an administrator on the group member terminals 410 and 420.

[0065] In other words, server 100 can issue an authentication number corresponding to the identification information of administrator terminal 310, which has been registered as an administrator on group member terminals 410 and 420. Administrator terminal 310 can then complete administrator authentication using the authentication number issued in accordance with the identification information. At this time, administrator terminal 310 can perform administrator authentication only once. For example, after launching the dedicated application, administrator terminal 310 can accept the terms of use for the dedicated application and the terms of use for managing personal location information. Next, administrator terminal 310 receives an authentication number issued by server 100 corresponding to the telephone number as unique identification information, and can log in to the dedicated application using the received authentication number. If an authentication number is not issued, administrator terminal 310 can request server 100 to retransmit the authentication number. Then, administrator terminal 310 can access group member terminals 410 and 420 by logging in to the dedicated application.

[0066] The group member terminals 410 and 420 and the administrator terminal 310 perform an operation to link the terminals together in order to receive location information from the group member terminals 410 and 420. As a result, the administrator terminal 310 manages the operation and related functions of the group member terminals 410 and 420, and the group member terminals 410 and 420 can operate according to the functions managed via the administrator terminal 310.

[0067] Although the present invention has been described above using several preferred embodiments, these embodiments are merely illustrative and not limiting. Anyone with ordinary skill in the art to which the present invention pertains should be able to make various modifications and alterations without departing from the spirit of the invention and the scope of rights disclosed in the appended claims.
