Best Mode for Carrying Out the Invention
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
FIG. 1 is a diagram illustrating a general example of a display method according to an embodiment of the present invention. In the display method, template data may be identically displayed with respect to a plurality of objects having same characteristics. In this instance, the template data may be generated by generalizing and characterizing modeling data with respect to the plurality of objects having the same characteristics. For example, the template data may include three-dimensional (3D) data identically corresponding to a plurality of objects having same characteristics from among objects displayed on a 3D map. As illustrated in FIG. 1, when it is assumed that first template data 101 is generated in association with objects 103 having a first characteristic, and second template data 102 is generated in association with objects 104 having a second characteristic, the first template data 101 may be repeatedly and identically displayed at locations for displaying the objects 103 on a map screen. Also, the second template data 102 may be repeatedly and identically displayed at locations for displaying the objects 104 on the map screen. For example, although a number of gas stations exist throughout a country, a shape of gas station building is similar. Accordingly, a characteristic of a gas station building may be generalized, and thus modeling data for a gas station may be used with respect to all gas stations buildings throughout the country.
FIG. 2 is a flowchart illustrating a display method according to an embodiment of the present invention. Each operation of the display method may be embodied by a display system according to an embodiment of the present invention. FIG. 2 illustrates the display method embodied by the display system.
In operation S210, the display system may maintain template data generated with respect to a plurality of objects having same characteristics. The template data may include modeling data identically generalized and characterized with respect to the plurality of objects having the same characteristics. The plurality of objects may have a same template identifier, and the display system may maintain the template data in association with the template identifier. The template identifier may be used for culling the template data. Also, the display system may store and maintain the template data in a template resource file. In this instance, the template data may include 3D data for the plurality of objects.
In operation S220, the display system may load all data in the template resource file to a memory when initializing. That is, all the data including the template data in the template resource file is loaded to the memory when initializing, and thus the template data may be displayed on a map screen more quickly. The loading in operation S220 may be selectively performed by the display system.
In operation S230, the display system may display the template data for the plurality of objects. In this instance, the display system may obtain a template identifier designated on map data and determine which template data is to be displayed on the map screen. Also, the display system may display the determined template data on a corresponding map screen. For this, the display system may perform retrieving in operation S231 and displaying in operation S232.
In operation S231 , the display system may retrieve template data corresponding to the template identifier designated on the map data. Since the template data for the plurality of objects is maintained in association with the template identifier in operation S210, the display system may retrieve template data through a template identifier of an object in a particular location on the map data.
In operation S232, the display system may display the retrieved template data on a map screen corresponding to the location where the template identifier is designated on the map data. That is, information provided through the map screen is based on the map data, and modeling data of the object corresponding to the particular location on the map data is to be displayed on the map screen. Accordingly, the display system may display the template data retrieved through the template identifier of the object corresponding to the particular location on the map screen, and thereby may display the object on the map screen. In this instance, since same template data is displayed with respect to the plurality of objects, modeling data for each of the plurality of objects is not required to be produced. Accordingly, costs associated with work and time may be reduced. Also, a single piece of template data is stored with respect to the plurality of objects, and thus data amount may be efficiently reduced. Also, since the data amount is reduced, all the template data may be loaded to the memory when initializing, and objects corresponding to each location on the map data may be quickly displayed on the map screen. FIG. 3 is a diagram illustrating an example of displaying template data for buildings having same characteristics according to an embodiment of the present invention. A map screen 300 where template data 301 for a gas station building is applied in a 3D navigation environment is illustrated in FIG. 3. That is, when displaying a 3D map such as the map screen 300 while loading all template data to a memory, a display system may read template identifiers designated on map data and retrieve template data corresponding to the template identifiers. Accordingly, the same template data 301 for three gas station buildings 302 to be displayed on the map screen 300 is displayed as illustrated in the map screen 300. That is, all the gas station buildings 302 may be displayed using the same template data 301 without generating modeling data of each of the three gas station buildings 302.
According to an embodiment of the present invention, although a gas station and a gas station building are described as an example, the present invention is not limited to the described embodiment. Also, it would be appreciated by those skilled in the related art that changes may be made to the exemplary embodiment. For example, template data for all objects, that may be easily ascertained by generalizing and characterizing, such as a post office and convenience store may be generated. Also, the above-described concept may be applied to all objects that may be displayed on the map screen.
FIG. 4 is a block diagram illustrating a configuration of a display system 400 according to an embodiment of the present invention. Here, the display system 400 may include a template data maintenance unit 410, loading unit 420, and template data display unit 430 as illustrated in FIG. 4.
The template data maintenance unit 410 may maintain template data generated with respect to a plurality of objects having same characteristics. The template data may include modeling data identically generalized and characterized with respect to the plurality of objects having the same characteristics. The plurality of objects may have a same template identifier. Also, the template data maintenance unit 410 may maintain the template data in association with the template identifier. The template identifier may be used for culling the template data. Also, the template data maintenance unit 410 may store and maintain the template data in a template resource file. In this instance, the template data may include 3D data for the plurality of objects. The loading unit 420 may load all data in the template resource file to a memory when initializing. That is, all the data including the template data in the template resource file is loaded to the memory when initializing, and thus the template data may be displayed on a map screen more quickly. The loading unit 420 may be selectively included in the display system 400. The template data display unit 430 may display the template data for the plurality of objects. In this instance, the template data display unit 430 may read a template identifier designated on map data and determine which template data is to be displayed on the map screen. Also, the template data display unit 430 may display the determined template data on a corresponding map screen. The template data display unit 430 may include a retrieval unit 431 and a display unit 432 for the displaying.
The retrieval unit 431 may retrieve template data corresponding to the template identifier designated on the map data. Since the template data maintenance unit 410 maintains the template data for the plurality of objects in association with the template identifier, the retrieval unit 431 may retrieve template data through a template identifier of an object in a particular location on the map data.
The display unit 432 may display the retrieved template data on a map screen corresponding to the location where the template identifier is designated on the map data. That is, information provided through the map screen is based on the map data, and modeling data of the object corresponding to the particular location on the map data is to be displayed on the map screen. Accordingly, the display unit 432 may display the template data retrieved through the template identifier of the object corresponding to the particular location on the map screen, and thereby may display the object on the map screen.
In this instance, since same template data is displayed with respect to the plurality of objects, modeling data for each of the plurality of objects is not required to be produced. Accordingly, costs associated with work and time may be reduced. Also, a single piece of template data is stored with respect to the plurality of objects, and thus data amount may be efficiently reduced. Also, since the data amount is reduced, all the template data may be loaded to the memory when initializing, and objects corresponding to each location on the map data may be quickly displayed on the map screen. According to an embodiment of the present invention, the display system and method displays objects having same characteristics on a map screen using same template data, reduces data amount, and thereby may reduce costs associated with time and work, efficiently display the template data for the objects, and efficiently display a 3D map. Also, the display system and method stores the template data through a file, loads all the template data to a memory when initializing, and thereby may display the template data more quickly.
The exemplary embodiments of the present invention include computer-readable media including program instructions to implement various operations embodied by a computer. The media may also include, alone or in combination with the program instructions, data files, data structures, tables, and the like. The media and program instructions may be those specially designed and constructed for the purposes of the present invention, or they may be of the kind well known and available to those having skill in the computer software arts. Examples of computer-readable media include magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD ROM disks; magneto-optical media such as floptical disks; and hardware devices that are specially configured to store and perform program instructions, such as readonly memory devices (ROM) and random access memory (RAM). Examples of program instructions include both machine code, such as produced by a compiler, and files containing higher level code that may be executed by the computer using an interpreter. The described hardware devices may be configured to act as one or more software modules in order to perform the operations of the above-described embodiments of the present invention, or vice versa.
