Description

TECHNICAL FIELD [0001] The present invention relates to a location mapping service providing system and a method for providing a location mapping service in a virtual space,

Embodiments relate to virtual space and real space mapping, and more particularly to techniques for mapping two spaces having different geographic information.

An application based on location awareness aims to provide necessary services at the corresponding location based on the location of the user. For example, there are applications that provide nearby restaurant information or recommend chatting by using nearby person information.

One example of applying these location-based applications to games is Supermono's Rescue Rush. The game uses Google map to create the same virtual map as the Google map around the user's current location, giving the user the feeling of being in the game space. In this case, however, the virtual space adopts the information of the real space as it is and uses 1: 1 mapping, so that the mapping of the real space and the virtual space can not be presented.

According to an aspect of the present invention, in order to solve the above-described problem, a location of a virtual space different from a real world is mapped using a current location information of a mobile application user to give a user a feeling of being present in a virtual space A service method and apparatus can be provided.

A system for providing a location mapping service in a virtual space according to an embodiment of the present invention includes a node setting unit for setting a plurality of first nodes and second nodes in each of a virtual space map and a real space map, A reference point determining unit for determining a first reference point and a second reference point among the first and second nodes and the virtual space map and the real space map into a plurality of regions corresponding to each other, And a controller for mapping the plurality of first nodes and the second nodes included in the corresponding plurality of regions using each vector information based on the reference point.

The reference point determination unit may calculate the number of other nodes adjacent to each of the first nodes and the second nodes, and may determine the node having the largest number of other calculated nodes as the first reference point and the second reference point, Respectively.

Also, the controller may divide the virtual space map and the real space map into four regions with the first reference point and the second reference point as a zero point, respectively, and match the same quadrants among the four regions.

The controller may modify the position of some of the first nodes if the number of the first nodes included in each of the corresponding plurality of regions does not match the number of the second nodes.

If the number of first nodes included in one area of the virtual area map is smaller than the number of second nodes included in one area of the real area map corresponding to the one area, The first node of the shortfall is moved from the other area adjacent to the one area to the one area.

The control unit may determine the first node of the shortage moved to the one area based on how close the first node is located to the one area.

If the number of first nodes included in one area of the virtual area is greater than the number of second nodes included in one area of the real area corresponding to the one area, And moving the excess first node to another area adjacent to the one area.

In addition, the control unit may determine the other area to be an area in which the excessive first node is located closest to the first area.

The control unit may further comprise a display unit, and the control unit controls the display unit to display, on the virtual space map, a positional change of the user on the physical space map based on the mapped first nodes and the second nodes .

The virtual space map and the real space map may be two-dimensional or three-dimensional information.

According to another aspect of the present invention, there is provided a method for providing a location mapping service in a virtual space, comprising: setting a plurality of first nodes and second nodes in each of a virtual space map and a real space map; Determining a first reference point and a second reference point among the first nodes and the second nodes, dividing the virtual space map and the real space map into a plurality of regions corresponding to each other, And mapping the plurality of first nodes and second nodes included in the corresponding plurality of areas by using the vector information of the plurality of first and second nodes.

The step of determining the first reference point and the second reference point may further include calculating the number of other nodes adjacent to each of the first nodes and the second nodes, And determining the node having the largest number as the first reference point and the second reference point, respectively.

The step of dividing the virtual space map and the real space map into a plurality of regions corresponding to each other may include dividing the virtual space map and the real space map into four regions with the first reference point and the second reference point as zero points, And associating mutually identical quadrants among the four regions with each other.

The step of mapping the plurality of first nodes and the second nodes included in the corresponding plurality of areas may include the step of mapping the number of the first nodes included in each of the corresponding plurality of areas to the number of the second nodes And if not, modifying the location of some of the first nodes.

If the number of first nodes included in one area of the virtual area map is smaller than the number of second nodes included in one area of the real area map corresponding to the one area, And moving the first node of the first region from one region adjacent to the one region to the one region.

The shortage of the first node moved to the one area may be determined based on how close the first node is located to the one area.

If the number of first nodes included in one area of the virtual area is greater than the number of second nodes included in one area of the real area corresponding to the one area, And moving the node to another area adjacent to the one area.

Also, the other region may be determined as an area where the excess first node is located closest to the first node.

The method may further include displaying the positional change of the user on the physical space map on the virtual space map based on the mapped first nodes and the second nodes.

In addition, the virtual space map and the real space map may be two-dimensional or three-dimensional information.

According to an aspect of the present invention, by mapping two maps of different characteristics, it is possible to help the user understand the position intuitively without violating the positional compatibility. This is because, as described above, the technique of mapping a geographical location to a virtual space enables a user to further strengthen the feeling of being present in the virtual world in an application such as a location-based mobile game utilizing the virtual world, .

For example, both an application running on a computer and a computer may correspond to a part, module, device or system of the present specification.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In addition, the size of each component in the drawings may be exaggerated for the sake of explanation and does not mean a size actually applied.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a configuration of a location mapping service providing system in a virtual space according to an embodiment of the present invention.

The location mapping service providing system 100 in the virtual space may include a node setting unit 101, a reference point determining unit 102 and a control unit 103. The location setting service providing system 100 may include a communication unit 104, (105), and a display unit (106).

The above system may be a server, a personal computer, or a portable communication device including a personal digital assistant. That is, it may include any mechanical device capable of performing mapping of the virtual space map and the real space map, which will be described later.

In one embodiment, the node setting unit 101 may set a plurality of first nodes and second nodes in each of the virtual space map and the real space map. The plurality of first nodes and second nodes set in each of the virtual space map and the real space map may be directly set by the user, or may be preset in the virtual space map or the real space map. In order to subsequently map the first node and the second node, the same number of first and second nodes may be set. At this time, it may be advantageous to adjust the node of the virtual space because there is a possibility that a perceptual error occurs if the node of the real space is adjusted.

The virtual space map is not a space for actually reading the position but a virtual space information that is mapped to the real space map and used in the program. Referring to FIG. 2A, the North Mediterranean map can be viewed as a virtual area map. In addition, the real space map means a reality map of the geographical location where the user exists. For example, the real space map may be any position on the earth including the location of the user identified by a Google map or the like. The virtual space map may be newly generated space information by a third party such as a user or a developer, or may be used by customizing an existing space. For example, in the former case, it may mean a map of a virtual space created directly by a user or the like, and in the latter case, a northern Mediterranean map may be used as a virtual space map.

In another embodiment, the virtual space and the real space may include three-dimensional and two-dimensional information, and the real space may be modeled and mapped to a specific shape and then mapped to a virtual space.

FIG. 2A is a diagram illustrating a method of generating a node in a real space map of a city in a city and setting a range. Since the virtual space map and the real space map must have a certain range, it may be necessary to set the boundary. Thus, in order to determine the range of the limited space, a finite number of nodes can be set on the virtual space map and the real space map. Referring to FIG. 2A, 25 nodes (25 phrases) represent the map of Seoul and 25 maps represent the northern Mediterranean map.

The reference point determination unit 102 may determine a first reference point and a second reference point, respectively, from a plurality of first nodes and second nodes that are set. That is, one reference point (i.e., first reference point) may be determined in the virtual space map, and one reference point (i.e., second reference point) may be determined in the real space map. Since the method of determining one reference point in each space map is the same, the process of determining the first reference point in the virtual space map will be described. This process can be adopted equally in the process of determining the second reference point.

3 is a flowchart illustrating a method of determining a reference point by the reference point determination unit 102 according to an embodiment of the present invention.

The reference point determining unit 102 may calculate the number of other nodes adjacent to the first nodes with respect to the first nodes (S31), and may determine the priority based on the calculated number of other nodes (S32). Then, the node having the largest number of calculated other nodes can be determined as the first reference point. Here, in order to determine the number of adjacent other nodes, the number of other nodes adjacent to one node may be determined by calculating the number of other nodes included in a certain radius with one node as the center of the circle.

FIG. 2B shows a map including a connection line connecting the nodes according to a certain rule by dividing the real space map of Seoul and the virtual space map of the Northern Mediterranean Sea into nodes. Referring to FIG. 2B, in order to determine the number of neighboring other nodes, based on a connection line between the first node designated by the user or the user, the connected (adjacent) other node may determine the first node as the first reference point have.

Then, the reference point determining unit 102 determines whether the first node is a single node (S33). If a first node exists, the reference point determining unit 102 may determine the node as a reference point (S35). If there are two or more first-ranked nodes having the same number of adjacent nodes, it is possible to determine a reference point by identifying a node having a high-ranking node around the node (S34, 35). This is to give a weight to a node with a high number of nodes in the vicinity, which can exist as a single optimized position.

FIG. 4 is a configuration diagram in which a reference point determining unit according to an embodiment of the present invention sets a reference point to any one of the nodes (19 and 29, respectively) determined in the virtual space map and the real space map.

Referring to FIG. 4, it can be seen that the node having the largest number of neighboring nodes is determined as a reference point. That is, it can be seen that the node (19) in the virtual space map and the node (29) in the real space map are determined as the reference points.

The reference point determination unit 102 searches for the most important node on the map and maps two spatial maps around the node so as to reduce the error from the spatial recognition as much as possible. The correspondence between the different virtual space map and the real space map can be greatly changed depending on where the reference point is determined.

The control unit 103 divides the virtual space map and the real space map into a plurality of regions corresponding to each other, and uses the vector information based on the first reference point and the second reference point to generate the plurality Lt; / RTI > can map the first and second nodes of the first node.

The control unit 103 can divide the virtual space map into four regions and similarly divide the real space map into four regions. The number of distinct regions can be the same in the virtual space map and the real space map.

In one embodiment, the process of dividing each map into a plurality of regions by the control unit 103 is the same in the virtual space map and the real space map, and will be described below based on the virtual space map. The process to be described later may be similarly applied to the real space map by the control unit 103. [

For example, the control unit 103 may form the perceptual coordinates using the first reference point determined by the reference point determining unit 102 as a zero point. That is, the control unit 103 can divide the virtual space map into four quadrants. However, the division into four areas is for the convenience of explanation, and the number of the divided areas may be divided into different numbers if the number of the virtual space and the actual space is the same.

Then, the control unit 103 can calculate vector information from the reference point to each node. That is, the control unit 103 can calculate information on the direction and the size on the two-dimensional plane. However, the scope of the present invention is not limited to the map on the two-dimensional plane.

The control unit 103 divides the virtual space map and the real space map into four regions with the first reference point and the second reference point as the respective zero points, and the same quadrants among the four regions can correspond to each other.

Thereafter, the control unit 103 can adjust the number of nodes included in each quadrant of the virtual space map and the real space map to be the same. In the following description, it is described that the position of the node of the virtual space map is changed based on the number of nodes for each quadrant of the real space map. In this explanation, the functions of the virtual space map and the real space map can be exchanged.

First, the control unit 103 compares the number of nodes located in the first quadrant of the virtual space map with the number of nodes located in the first quadrant of the real space map. If the number of nodes in the first quadrant to the fourth quadrant is the same, the control unit 103 can map the nodes located in each quadrant to each other based on the vector information from the reference point. 4, the node 11 maps to the node 21 and the node 12 maps to the node 21, because in the first quadrant the node 11 is close to the reference point 19 and away from the X axis, (22).

However, in an embodiment of the present invention, since the virtual space map and the real space map may have different shapes without being matched one by one, the number of nodes included in each corresponding quadrant may not be the same .

Accordingly, if the number of the first nodes included in each of the plurality of corresponding areas does not match the number of the second nodes, the control unit 103 can modify the positions of some of the first nodes.

Specifically, when the number of nodes included in one area of the virtual area map is smaller than the number of nodes included in one area of the real area map corresponding to one area (see each quadrant of FIG. 4) , It is possible to move the deficient node to another area adjacent to the one area in the virtual area map. The position to be moved may be the boundary of the two regions, or it may be an arbitrarily defined position. In other words, nodes can be taken and supplemented in other areas of the same space. In addition, the control unit 103 can determine a shortcoming node to be moved to one area based on how close the node is to the one area.

If the number of nodes included in one area of the virtual area is larger than the number of nodes included in one area of the real area corresponding to one area (see the third quadrant in FIG. 4) , And an excess node can be moved to another area adjacent to the one area. Also, the control unit 103 may determine the other area as the area where the excess node is located closest to the node.

Hereinafter, a description will be given of determination of a node region having a deficient node, a node of the region, and a method of determining an excess node export region and the node.

FIG. 5 is a flowchart illustrating a process of matching the number of nodes in each region between a virtual space and a real space in an embodiment of the present invention.

In the case of bringing in a defective node, the control unit 103 determines that the first quadrant is | y | / | x | The larger the node, the | quadrant | x | / | y | A node with a large value is brought to the first quadrant in the ascending order of size. The second quadrant is | quadrant | y | / | x | The larger the node, the | quadrant | x | / | y | The largest nodes in the list are brought to the second quadrant. The third quadrant is | quadrant | y | / | x | The larger the node, the | quadrant | x | / | y | The larger nodes are brought in the third quadrant in the larger order. The fourth quadrant is | quadrant | y | / | x | For large-value nodes, | quadrant | x | / | y | Among the nodes with large values, they are brought to the fourth quadrant in the largest size order.

When the excess node is to be exported, the controller 103 calculates the vector information of each node based on the node in the reference space, and moves the node having the least similarity to another area. For example, in the first quadrant, an excess node with the lowest similarity of vector information can be pushed to quadrant 2 if | y | / | x | is greater than 1, or to quadrant 4 if less than 1. The position to be moved may be the boundary of the two regions, or it may be an arbitrarily defined position.

However, in order to shorten the above process, the control unit 103 can fill the quadrant with a small difference in the number of nodes between the real space and the virtual space. This is because by not moving many nodes in one quadrant, it reduces the errors of cognition caused by the movements, and by shifting the nodes of the smaller number of nodes to the higher priority, it is possible to reduce the difference in the number of nodes among each quadrant more quickly.

The controller 103 aligns the number of nodes with respect to each quadrant, and associates the nodes 1: 1 on the basis of vector information (distance and direction) about the reference point. When matching, match the distant node as long as it does not violate | x | / | y | ratio. In other words, it is necessary to correspond nodes in the vicinity of a node that is far from the reference point, and in particular, to cope with a range in which the position of the distant node does not deviate greatly from the directionality. The reason for responding from distant nodes is to reduce the cognitive error as much as possible because the direction is clear as the distance increases.

FIG. 6 is a view showing nodes of the map of Seoul (reality space map) and the map of northern Mediterranean map (virtual space map) according to an embodiment of the present invention.

6, the middle point 62, which is the nearest node to the eucalyptus 61 as a reference point in the physical space map (FIG. 6A), is located to the north than the reference point, but the reference point HERDER 71 to the Groningen 72 which is located on the east side. Directional errors are inevitable because they are based on two different maps. However, the present invention can minimize cognitive error and provide logically reasonable positional compatibility by maximizing directionality and mapping each node with distance first.

The control unit 103 maps the map of the virtual space and the map of the real space through such a process, thereby minimizing the heterogeneity between different geographical information.

The location mapping service providing system 100 in the virtual space may further include a communication unit. The communication unit 104 may include any device that the system 100 can communicate with outside, and may include a GPS device for locating a user. 2G / 3G / 4G, digital subscriber line (DSL), asynchronous transfer mode (ATM), and the like are used to perform a wireless Internet environment. , An infiniband, a PCI Express Advanced Switching, and the like.

In addition, the location mapping service providing system 100 in the virtual space may further include a user interface unit 105. The user interface unit 105 may be any device including a keyboard, a mouse, a touch pad, and a touch screen capable of receiving user input.

In addition, the position mapping service providing system 100 in the virtual space may further include a display unit 106. The control unit 103 controls the display unit 105 such that the nodes of the mapped virtual space map and the nodes of the real space map The control unit may control the display unit 105 to display a change in the position of the user on the physical space map on the virtual space map. That is, the position of the user in the real space detected by the GPS or the like can be confirmed on the real space map, and the position can be displayed on the mapped virtual space map. The moving position of the user can be displayed in a mapped ratio in the mapped virtual area map with the distance and direction moved in the real space. In addition, the control unit 103 can centrally process all the information exchange and processing among the respective components in the above system 100.

7 is a flowchart illustrating a method of providing a location mapping service in a virtual space according to another embodiment of the present invention. A method for providing a location mapping service in a virtual space includes: setting a plurality of nodes in each of a virtual space map and a real space map in operation S71; determining reference points in a set plurality of nodes in operation S72; (S73) of dividing the real space map into a plurality of regions corresponding to each other, and mapping a plurality of nodes included in the corresponding plurality of regions using each vector information based on the reference point (S74) can do. This method and its detailed procedure can be performed in the same manner as described for the configuration of the location mapping service providing system 100 in the virtual space.

However, it should be understood that such modifications are within the technical scope of the present invention.
