Description

[Technical Field]

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

[0002] The recent increase in the number of tourists has been remarkable, and the content provided to tourists is also increasing. Conventional tourist information content usually consists of tourist maps that show the locations of tourist attractions, restaurants, accommodations, etc. However, because such tourist maps only show simplified information, tourists may encounter more or less limitations in navigating their destinations using only the map.

[0003] Tourist maps have the extremely important function of compressing everything about tourism and allowing people to experience the culture at a glance, and as they convey tourist destination information, transportation, history, and culture all at once, there is a constant demand for improvements. The types of tourist maps that have been mainly used so far can be broadly categorized into general map application types, transportation / tourism combined types, and 3D map types.

[0004] The general map application type follows the notation format of a general map but is edited in a simple format focusing on information about tourist destinations. This has the advantage of being easy to produce, but the disadvantage is that it is aesthetically inferior and does not fully fulfill its role of conveying an image or promoting tourism. The transportation / tourism combined type is created based on the national basic map, displaying roads and areas and inserting illustrations and photographs of major tourist destinations. This can enhance the aesthetic communication effect of tourist destinations, but it still has visual complexity because it uses the road system of the basic map as is. The 3D map type is created in a 3D shape using perspective projection, and although it has difficulty accurately conveying location and geographic information, it has the advantage of being able to show the characteristics of tourist destinations in 3D. These types of conventional tourist maps are based on the road system of the basic map and are produced in a format that only adds visual effects to tourist spots, and surrounding mountains are drawn using contour lines or the same pattern along the north-south direction, which means that they are different from what is visually recognized when actually driving through tourist spots within local government units at the county level in Korea (roughly equivalent to a county in Japan), and this creates the problem of poor usability.

[0005] Although existing maps play a vital role in compressing all information and allowing people to experience a culture at a glance, their limitations in conveying images and providing spatial information remain a problem. In particular, the mountainous terrain of Korea clearly limits the information that flat maps can provide, making the visibility and information transmission capabilities of 3D maps essential.

[0020] FIG. 1 is a diagram showing an outline of the configuration of a 3D map providing system according to a first embodiment of the present invention.

[0021] Referring to FIG. 1, a 3D map providing system according to a first embodiment of the present invention includes a server 100 and a user terminal 200. The server 100 and the user terminal 200 are connected to each other via a network.

[0022] The user terminal 200 is a terminal capable of communicating via a wireless communication network, and can be realized by a wide variety of devices such as a mobile phone, a smartphone, or a tablet PC.

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

[0024] The server 100 communicates with the user terminal 200 via a wireless communication network, combines spatial information and location information for each region to generate a 3D solid map, and provides the 3D solid map to the user terminal 200 via a dedicated application.

[0025] When generating a 3D map, the server 100 can display the geological structure in different colors.

[0026] When generating a 3D relief map, the server 100 can display it in different colors depending on the altitude.

[0027] The server 100 can display related information including public institutions, schools, tourist attractions, ports, airports, and walking courses on the 3D map.

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

[0029] Fig. 2 is a diagram schematically illustrating the configuration of a 3D relief map providing system according to a second embodiment of the present invention, and illustrates the provision of a group management function in the 3D relief map providing system according to the second embodiment of the present invention.

[0030] 2, the server 100 can provide a group management function to user terminals 310, 410, and 420 that have registered a group 10 through a dedicated application. At this time, when registering a group, one or more user terminals can be registered as an administrator terminal 310, and the remaining user terminals can be registered as group member terminals 410 and 420. The server 100 can provide a group management function including different functions to the administrator terminal 310 and the group member terminals 410 and 420 through a dedicated application.

[0031] FIG. 3 is a flowchart showing the process of determining a dangerous area in a 3D map providing system according to one embodiment of the present invention, and FIG. 4 is a diagram illustrating types of danger information according to one embodiment of the present invention.

[0032] 3 and 4, the server 100 generates a draft of a 3D map (S101) and collects two or more types of risk information (S103). In one embodiment of the present invention, the server 100 may collect risk information such as geographic risk information, seasonal (time) risk information, warning information, weather risk information, and traffic risk information. In this case, the server 100 may collect the risk information through the servers of related public institutions or information providers. For example, weather risk information may be collected through a server of the Japan Meteorological Agency, and traffic risk information may be collected through a server of the National Police Agency.

[0033] In Figure 4, examples of geographical hazard information include cliffs, rockfall areas, ponds, seashores, and riversides; seasonal hazard information includes flood season and avalanche season; warning information includes rainfall, snowfall, rapids, the appearance of dangerous people, the appearance of dangerous animals, the release of dangerous substances, pests, and diseases such as foot-and-mouth disease; meteorological hazard information includes volcanoes, earthquakes, tsunamis, extreme heat, heavy snow, heavy rain, and extreme cold; and traffic hazard information includes traffic congestion, road closures, and detours.

[0034] If there are two or more types of danger information collected (S105), the server 100 determines that the area is a danger area (S107). For example, if there is cliff information and rainfall information about the area, the area is determined to be a danger area.

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

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

[0037] 5, the server 100 provides the administrator terminal 310 with a function for setting a region of interest and a no-go area on a 3D map through a dedicated application. In this case, the server 100 may provide a function for inputting the region of interest and the no-go area by freely drawing a line on the 3D map when setting the region of interest and the no-go area, and using this function, a closed curve input from the administrator terminal 310 can be set as the region of interest and the no-go area. In one embodiment of the present invention, the server 100 may restrict the no-go area to be set within the region of interest.

[0038] When an area of ​​interest and a restricted area are set by the administrator terminal 310 (S201), the server 100 generates a feature map that simply displays the area of ​​interest with the main points at the center (S203).

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

[0040] The server 100 transmits information on the area of ​​interest and the restricted area, and information on the feature map and the detailed location map to the manager terminal 310 and the group member terminals 410 and 420 (S207).

[0041] The server 100 provides the terminals 310, 410, 420 with a 3D map showing the areas of interest and the restricted areas, and displays the current positions of the terminals 310, 410, 420 on the map (S209).

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

[0043] FIG. 6 is an exemplary diagram illustrating setting of an area in a 3D map providing system according to an embodiment of the present invention.

[0044] 6 shows an example of a 3D map of Jeju Island in Korea displayed on a mobile device, 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 around Mt. Halla and Baekrokdam.

[0045] The region of interest 610 and the restricted area 620 can be set by inputting a closed curve on a 3D map from a dedicated application via an input unit provided in the administrator terminal 310. 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, or if the input unit is a touchscreen, the closed curve can be input using a finger or the like. For example, if an area that needs to be restricted from entry, such as a lake, exists within an accessible region of interest, the restricted area 620 can be set within the region of interest 610.

[0046] In FIG. 6, the server provides a "feature map" icon 630 on a portion of the screen, and when the "feature map" icon 630 is selected, a feature map is provided that shows a simplified view of the main points of the region of interest 610.

[0047] FIG. 7 illustrates a characteristic diagram of a 3D map providing system according to one embodiment of the present invention.

[0048] The feature map of Figure 7 illustrates an example of a feature map for the area of ​​interest 610 shown in Figure 6, in which Jeju Airport 710, Seongpanak Rest Area 720, Seogwipo Recreational Forest 730, and Horse Riding Park 740 are illustrated as major points and displayed as simple icons or blocks. When a major point is selected from the feature map, the server 100 provides a point details map, which is a map displaying detailed information about the selected major point.

[0049] Figure 8 is a diagram illustrating a detailed location map in a 3D relief map providing system according to an embodiment of the present invention. The detailed location map illustrated in Figure 8 is an example of a detailed location map for Jeju Airport 710 in Figure 7. In this way, the present invention provides an interface that allows users to quickly and easily move to a specific area from the 3D relief map screen using a feature map showing main locations and a detailed location map showing detailed information about the main locations.

[0050] FIG. 9 is an exemplary diagram illustrating a process of checking the location of a terminal and determining whether or not the terminal has left an area in a 3D map providing system according to an embodiment of the present invention.

[0051] 9, the group member terminals 410 and 420 may transmit location information to the server 100 via a base station 910 linked to the server 100. The server 100 may receive the location information measured by the group member terminals 410 and 420 from the base station 910 and 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 may measure their locations using at least one of a GPS positioning method, a WIFI positioning method, and a CELL positioning method. In this case, the positioning method may be adaptively changed depending on the external environment in which the terminal is located, and the location may be measured using the changed method.

[0053] The server 100 can then transfer the determination result related to the area of ​​interest 610 determined based on the location information of the group member terminals 410 and 420 to the manager terminal 310. Specifically, the server 100 can determine whether the group member terminals 410 and 420 are present in the set area of ​​interest 610 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, 420 are present in the area of ​​interest 610, the server 100 can transfer to the administrator terminal 310 whether or not they have left the area of ​​interest 610 or entered the restricted area 620.

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

[0056] The server 100 can determine whether the group member terminals 410, 420 have left the region of interest 610. In other words, the group member terminals 410, 420 may have moved and moved to a location where they have left the region of interest 610. The server 100 can re-receive location information at the point where the group member terminals 410, 420 have moved. Then, the server 100 can determine that the group member terminals 410, 420 have left the region of interest 610 based on the re-received location information of the group member terminals 410, 420, and transmit the determination result regarding this to the manager terminal 310.

[0057] Next, depending on whether or not there has been a departure, the administrator terminal 310 can take prompt action in response to the situation in which the group member terminals 410, 420 have left the area of ​​interest 610, by triggering sensors on the group member terminals 410, 420, making phone calls, or forwarding messages.

[0058] In addition, the server 100 logs the locations from which the group member terminals 410 and 420 have left, and can use the logged locations as information for resetting the safety area in the future.

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

[0060] In short, the server 100 can provide the administrator with information that can be quickly recognized regarding the sudden situation of a group member by determining whether or not the group member is located within the area set by the terminal based on the location information measured from the group member terminal 410, 420.

[0061] At this time, the member terminals 410, 420 and the manager terminal 310 may have completed an authentication process for receiving location information of the member terminals 410, 420 based on the communication service. In other words, the member terminals 410, 420 can perform manager registration for the manager terminal 310 for managing the locations of the member terminals 410, 420. Then, the manager terminal 310 can link with the member terminals 410, 420 by performing manager authentication for the member terminals 410, 420 for which manager registration has been completed. Then, the manager terminal 310 can receive location information measured from the member terminals 410, 420.

[0062] The member terminals 410 and 420 may perform administrator registration for the administrator terminal 310 that wishes to check the locations of the member terminals 410 and 420. Here, administrator registration may refer to registration for the administrator terminal 310 that can receive location information from the member terminals 410 and 420. In other words, administrator registration may refer to an application to grant the administrator terminal 310 permission to use functions that can manage the member terminals 410 and 420.

[0063] Then, the administrator terminal 310 can perform administrator authentication for the group member terminals 410 and 420 for which administrator registration has been completed, using a dedicated application capable of managing the functions of the group member terminals 410 and 420. Here, administrator authentication may mean acceptance of administrator registration performed in the group member terminals 410 and 420. That is, administrator authentication may mean acceptance of administrator registration requested from the group member terminals 410 and 420 to manage functions related to the group member terminals 410 and 420, such as calls, messages, location confirmation, schedule confirmation, activity amount, and environment settings of the group member terminals 410 and 420.

[0064] Specifically, after the administrator terminal 310 accepts the usage agreement regarding the management terms and conditions for the group member terminals 410 and 420 using a dedicated application, the administrator terminal 310 can perform administrator authentication based on the unique identification information assigned to the administrator terminal 310. Here, the administrator terminal 310 can perform administrator authentication in accordance with the identification information of the administrator terminal 310 for which administrator registration has been performed on the group member terminals 410 and 420.

[0065] In other words, the server 100 can issue an authentication number corresponding to the identification information of the administrator terminal 310 for which administrator registration has been performed on the group member terminals 410 and 420. The administrator terminal 310 can then complete administrator authentication using the authentication number issued corresponding to the identification information. At this time, the administrator terminal 310 can perform administrator authentication only the first time. For example, after launching a dedicated application, the administrator terminal 310 can accept the terms of use for the dedicated application and the management terms for personal location information. The administrator terminal 310 then receives an authentication number issued by the server 100 corresponding to a phone number as unique identification information, and can log in to the dedicated application using the received authentication number. If the authentication number was not issued, the administrator terminal 310 can request the server 100 to retransmit the authentication number. The administrator terminal 310 can then access the group member terminals 410 and 420 by logging in to the dedicated application.

[0066] The group member terminals 410, 420 and the administrator terminal 310 perform operations to link the terminals together in order to receive location information of the group member terminals 410, 420, so that the administrator terminal 310 manages functions related to the operations of the group member terminals 410, 420, and the group member terminals 410, 420 can perform operations 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. A person skilled 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 present invention and the scope of rights disclosed in the appended claims.
