Description

Position Marking method on the painting map}

The present invention relates to a method of displaying a location of a picture map which has improved visual reliability and reliability in displaying a real location in a picture map having improved visual convenience and usability.

With the balanced development of land development and the increasing activity of people due to transportation and communication development, more specific and accurate information on location and geography is required.

As a result, interest in maps has increased, and according to this, various devices for automatically guiding various terrain information have been developed and provided. Representatively, a navigation system combining a global positioning system (GPS) and an electronic map is provided. There is this.

Electronic maps, which are applied to general maps and navigation systems, are produced by reducing the actual geography and terrain to an accurate scale, so that users can easily identify the location of a specific point through the map. Since the terrain information can be provided in real time, the user can easily find the destination even in a place where the geography and the terrain information are unfamiliar when the vehicle is used.

However, these (electronic) maps are produced with accurate scales, so the appearance of the surrounding environment cannot be expressed at all, and only the uniform topography and buildings are repeatedly represented on the (electronic) maps. It was difficult to feel the identity of the map and the real place.

In addition, the (electronic) map has a lack of familiarity with reading a map due to the hard expression as described above, and this disadvantage has caused a difficulty for the user to read and understand the map.

In order to solve these problems and minimize the user's objection to the use of maps, picture maps have been introduced to increase the utilization of maps.

The figure map shows the actual location of the actual place by hand or various software while maintaining the minimum scale state. The artificial maps such as buildings can be expressed in warm colors and shapes for visual familiarity, As shown in the figure, the user can easily think of and adapt the shape of the actual place.

As a result, users can access maps emotionally, minimizing the disapproval of map use and increasing the intimacy, and ultimately make it possible to apply and expand various businesses through picture maps. I did it.

However, as described above, such a map is relatively inconsistent with scale compared to the (electronic) map, and thus its use is limited to a simple tourist guide or a map.

Of course, the use of GPS-based picture maps can not be confident in the reliability of the guide information in the equipment that must be secured with accurate guide information, such as navigation, the use of the picture map has been practically limited.

Accordingly, the present invention has been invented to solve the above problems, it is possible to contribute to the daily use of the map by increasing the reliability of the location guide when using the GPS-based map, and maintaining the advantages of the map to the maximum It is a technical problem to provide the position display method of a figure map.

The present invention to achieve the above technical problem,

A first step of checking the GPS coordinates of the user where the user is located;

A second step of retrieving and outputting a picture map showing a region to which a user's GPS coordinates belong, wherein the picture map is an image file including GPS coordinates of a specific location and location information including pixel information for output;

A third step of searching for the GPS coordinates of a specific position adjacent to the GPS coordinates of the user and setting the reference point within the range shown by the figure map;

A fourth step of retrieving the GPS coordinates of the reference point from the location information of the figure map and setting pixel information of the corresponding location information as the reference point of the figure map;

After converting the GPS coordinates of the user and the GPS coordinates of the reference point into pixels for output of the picture map, the user traces the location point of the user based on the pixel information of the reference point identified in step 4, and then the pixel of the corresponding location point A fifth step of confirming information; And

A sixth step of driving the corresponding pixel of the output means according to the pixel information of the location point and displaying the same on the picture map;

Position display method of the picture map including a.

According to the present invention, it is possible to provide terrain information with improved reliability while maintaining the advantages of the friendly map, thereby increasing the utilization rate of the map, thereby greatly expanding the field of application of the map. There is.

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

1 is a view showing an embodiment of a picture map, FIG. 2 is a view showing another embodiment of a picture map, Figure 3 shows a state of the map of the place pointed to the picture map of Figs. One of the drawings will be described with reference to this.

As illustrated in FIG. 1 and FIG. 2, the figure map shows the topography of various regions and the appearance of various buildings, and may have various feelings according to the expression method and the color used. The characteristics of the figure map can be easily confirmed when compared with the map of FIG. 3 representing the same region as that of FIGS. 1 and 2.

On the other hand, as shown in Figures 2 and 3, the map may also have a mini-map (MM, MM ') and scale control bar (B, B') like the actual map. The mini-maps (MM, MM ') is to be able to display the part that is being enlarged and displayed on the monitor while separately outputting the entire image of the picture map, the user is enlarged and output using the mini-map (MM, MM') It makes it easy to change to a specific location while checking the approximate location of a portion of the picture map.

For example, FIGS. 1 to 3 illustrate a map and a general map showing topographical information between 'Gangnam Station Crossroad' and 'Kyobo Tower Crossroad', and the user may select a nearby area centered on 'Gangnam Station Crossroad'. If you want to enlarge the output area near 'Kyobo Tower Intersection' while printing it on the monitor, you can easily adjust the terrain information displayed on the monitor by selecting the location on the mini map (MM, MM). have.

On the other hand, the size of the terrain information output to the monitor can be adjusted by the scale control bar (B, B '). Since the scale control bar (B, B ') is a well known technique, additional description is omitted.

Therefore, it is desirable for the picture map to show the topography of the wide area as much as possible, through which the same performance as the electronic map can be achieved. However, since the map is shown by hand, etc., it is inevitably separated by a certain range unlike the electronic map. That is, the figure map of FIG. 1 and FIG. 2 only shows the topographical information between the 'Gangnam Station crossroad' and 'Kyobo Tower crossroad', because it is inevitable due to the limitation of the ground on which the figure map is shown. As a result, other periphery of the terrain information shown in Figs. 1 and 2 can only be obtained through other maps.

This will be described again below.

4 is a block diagram illustrating a configuration of a terrain information guide system for performing a method of displaying a location of a picture map according to the present invention.

As described above, the figure map and the general map show the reduced terrain information. In the general map, the scale ratio is strictly applied, whereas the scale map has a relatively uneven scale ratio. Therefore, if the picture map is combined with the GPS in the same manner as the general map, the location point displayed on the picture map may be different from the actual location required by the user. That is, assuming that the actual position required by the user between any first reference point and the second reference point is closer to the first reference point, if the point indicated by the GPS is displayed as it is, the accumulation ratio is secured. In the non-picture map, the actual position cannot be guaranteed between the first reference point and the second reference point, and even though the actual position is displayed between the first and second reference points, the actual position closer to the first reference point is displayed. It may be indicated as being located closer to the second reference point in the pictorial map.

In order to compensate for this problem, the method of displaying the location of the figure map according to the present invention proceeds through the following terrain information guide system.

The terrain information guide system includes: a GPS module 100 for communicating with a GPS satellite 200, a main module 300 having information, coordinates, and pixel information about an electronic map and a picture map, which are general maps, and calculating and controlling the same; It includes an input module 400 and an output module 500 for outputting the final map while controlling the main module 300.

On the other hand, the main module 300 is an electronic map DB (301) for storing the electronic map data, a coordinate DB (302) for storing the coordinate data applying the coordinates of the GPS to the electronic map, and a figure for storing the map data A map DB 303, a pixel information DB 304 for storing pixel information occupied when the picture map is output to the output module 500, and a search for the DBs 301, 302, 303 and 304, respectively. Digital map search module 305, coordinate search module 306, picture map search module 307 and pixel information search module 308, the output module by combining the data of the GPS 100 and the electronic map DB (301) Outputs through 500 and combines the data of the GPS (100) and the picture map DB (303) combined output module 309 and outputs through the output module 500, the coordinate data of the GPS (100) map In the application to a location tracking module 310 for tracking the location of the operation.

Detailed description thereof will be described with reference to the flowchart of FIG. 5.

5 is a flowchart sequentially illustrating a method of displaying a location of a figure map according to the present invention.

S10; System run step

Run the terrain information guide system. At this time, since the configuration (100, 200, 300, 400, 500) of the terrain information guide system as described above is presented as an embodiment, it is not limited thereto. In addition, since the components 301, 302, 303, 304, 305, 306, 307, 308, 309, 310 of the main module 300 are also presented as an embodiment, the configurations 301. 302. 303. 304. 305. 306. 307. 308. 309. 310 may be variously modified as necessary.

As is well known, the plurality of GPS satellites 200 communicate with the GPS 100 on the ground, and determine and display unique coordinates for each terrain on the earth. That is, after confirming the position of a specific object in the GPS satellites 200 to output and display the coordinates corresponding to the position. On the other hand, for the convenience of the user, an electronic map that records the terrain information corresponding to the coordinates is output instead of the coordinates. As a result, the user can easily understand the location information by checking the location of the specific object on the electronic map.

For reference, the coordinate DB 302 stores GPS unique coordinate data, and the electronic map DB 301 stores terrain information data associated with the unique coordinates.

On the other hand, the picture map DB 303 stores an image file showing the terrain information of a specific region as a picture, the pixel information DB 304 is the position of the pixel occupied when the image file is output to the output module 500 Save the information. In this case, the location information of the pixel stored in the pixel information DB 304 may include all parts shown in the picture map, but in this case, the size (amount) of the location information of the corresponding pixel may be excessively increased for each picture map. Therefore, the position information of the pixel stored in the pixel information DB 304 may be limited to a specific reference point. That is, in the latter case, several representative points of an arbitrary picture map are determined, and the picture map includes only the location information of the pixel from which the point is output.

Subsequently, an image file of a picture map can be recorded and stored in a format of * .jpg, * .gif, * .tif, etc., which are extensions of a general picture file, but is not limited to a specific image format.

S20; Picture map output stage

During the operation of the terrain information guide system having the above-described configuration, the user may be provided with the terrain information and the location information for a specific point through a general electronic map, but may check this on the figure map. Accordingly, the merge output module 309 checks the topographic information and the location information of the specific point tracked by the GPS 100, and then uses the picture map search module 307 to display the picture map including the topographic information and the location information. Retrieve from the DB 303.

For example, a user located between 'Gangnam Station Crossroad' and Kyobo Tower Crossroad 'may output the location information and the terrain information through the input module 400 in order to check the location information and the terrain information about the surroundings. Upon request, the terrain information guide system drives the GPS 100 to determine the user's location and then transfers the coordinates.

The electronic map search module 305 or the figure map search module 307 searches the electronic map DB 301 or the figure map DB 303, respectively, based on the received coordinates to find the corresponding electronic map or figure map. Here, since the present invention relates to a method for displaying a specific point on a picture map, the picture map search module 307 finally searches for a picture map DB 303 and includes an area transmitted from the GPS 100. Will retrieve a picture map image file.

On the other hand, as described above, due to the limitation of the surface of the figure map, the range that one image file can represent may be limited. Therefore, it is necessary to search for an image file containing a region including location information and terrain information requested by the user.

In general, when the image file is stored in the picture map DB 303, the coordinates corresponding to the boundary of the picture map (hereinafter referred to as the boundary coordinate) are also stored together, so that the picture map search module 307 is transmitted from the GPS 100. The image file of the corresponding picture map will be searched by checking the boundary coordinates surrounding the coordinates of the location information.

However, the method of retrieving the image file for the corresponding picture map from the picture map DB 303 based on the coordinates transmitted from the GPS 100 varies depending on the format of the image file or the contents of the picture map. The scope of rights is not limited to the above-described embodiment.

In another embodiment, an image file of a picture map may be added and updated to an image file of an existing picture map every time the corresponding picture map is generated, so that the image file of the picture map is recorded and stored as one image file. In this case, the part of the picture map including the coordinates transmitted from the GPS 100 checks pixel information corresponding to the coordinates in the picture map so that only the corresponding part is output.

In addition, when a picture map is stored and stored as a plurality of image files, the image map of the corresponding picture map including the coordinates transmitted from the GPS 100 does not output only one image file adjacent to the arrangement by arranging You can also print them out in batches.

As such, the method of outputting the picture map is variously modified according to the format and output method of the image file containing the information on the picture map.

S30; Reference value GPS coordinate check step

A pictorial map contains location information for a specific location. That is, as shown in Figures 1 and 2, 'Kyobo Tower crossroad', 'Gangnam Station crossroad', 'Seocho Elementary School (see Fig. 8) and the like.

Such location information includes coordinates and pixel information used by the GPS 100. As a result, the image file for the arbitrary picture map includes coordinates and pixel information about points such as Kyobo Tower Intersection, Gangnam Station Intersection, and Seocho Elementary School.

Therefore, when the user manipulates the terrain information guide system to display his location information on the picture map, the merge output module 309 performs the picture map search module 307 according to the coordinates of the user transmitted from the GPS 100. The figure map DB 303 is searched for, and the location information of the figure map retrieved from the figure map DB 303 is checked.

Here, the various location information is a reference value for tracking the user's own location information, and the location information that is valuable as the reference value is the electronic map DB 301, the coordinate DB 302, the picture map DB 303, and the pixel information. All of the DBs 304 are searched and selected.

In more detail, the picture map search module 307 may search for a corresponding picture map image file in the picture map DB 303 using the coordinates of the point where the user is located. However, since the location where the user is located in the picture map cannot be displayed using only the coordinates, the location information of another point that can be a reference in the picture map should be found.

The location information can be confirmed in the electronic map DB 301 and the coordinate DB 302, and the location information thus identified is finally selected by using whether or not it exists in the corresponding map and used as a reference value. For reference, since the map may have less location information than the conventional electronic map, it is necessary to confirm whether the location information checked by the electronic map DB 301 and the coordinate DB 302 is information included in the map. something to do. However, the above-described procedure may be omitted if the location information of the various points is the same on the electronic map and the figure map.

S40; Steps to check baseline image pixels

The merge output module 309 checks a point of the figure map corresponding to the reference value confirmed in the reference value GPS coordinate checking step (S30), and the pixel information of the corresponding point is converted into pixels through the pixel information search module 308. The information is retrieved from the DB 304.

S50; Position point operation tracking step

The location tracking module 310 compares the location coordinates of the user and the reference value coordinates transmitted from the GPS 100, tracks the location and distance of the location coordinates based on the reference value coordinates, and secures data necessary for the calculation.

Meanwhile, by applying the data to the pixel information of one point corresponding to the reference value, the user's position is traced back on the corresponding picture map, and the pixels of the tracked point are identified.

A more detailed description of the tracking operation method will be described below in detail through the embodiments.

S60; Show step on the map

The location point operation tracking step (S50) is driven by driving the pixel of the operation point tracked to output the display, the user can check his position on the picture map.

Of course, since the location of the user output on the picture map is almost the same as the actual terrain, the user can be provided with accurate road guidance and topographic information as well as his location confirmation through the picture map.

In the method for displaying a position of a picture map according to the present invention described above, the description of the reference value GPS coordinate checking step (S30) to the location point calculation tracking step (S50) will be described in more detail with reference to the embodiment.

6 is a view schematically showing the first and second embodiments to which the method for displaying a location of a figure map according to the present invention is applied.

As illustrated in FIGS. 3 and 6, one or two reference values retrieved in the reference value GPS coordinate checking step S30 may be provided.

1) First embodiment

3 and 6 (a), the position tracking module 310 selects one reference value in the reference value GPS coordinate checking step (S30) and sets the coordinate as the first reference point RSP1, and GPS A distance RD1 between two points RSP1 and RP is calculated using the user's coordinates transferred from 100 as the user location point RP.

In addition, since the direction of the first reference point RSP1 can be tracked based on the location point RP through the coordinates of the user location point RP and the first reference point RSP1, in the figure map, The location point P may be identified on the figure map by tracing the direction of the location point P through the pixel based on the first reference point SP1.

As a result, since the figure map is shown to a certain scale, the distance RD1 between the first reference point RSP1 and the user location point RP is converted into the scale of the corresponding figure map to convert the first reference point SP1 of the figure map. The user location point P in the distance D1 accumulated as a reference is tracked and displayed.

2) Second embodiment

As shown in Figure 3 and 6 (b), the position tracking module 310 selects two reference values in the reference value GPS coordinate check step (S30) and the coordinates of the first and second reference points (RSP1, RSP2, respectively) ), And the distances RD1 and RD2 between the three points RSP1, RSP2, and RP are calculated using the coordinates of the user transmitted from the GPS 100 as the user location point RP.

In this case, the distances RD1 and RD2 do not measure and apply the actual distance as in the first embodiment, but check the ratio of the two distances RD1 and RD2 and apply them to the figure map.

As a result, the user position point P of the distances D1 and D2 satisfying the ratio based on the first and second reference points SP1 and SP2 of the figure map corresponding to the first and second reference points RSP1 and RSP2. And track it.

In this process, the user location point P displayed on the figure map is improved in reliability relative to the location in proportion to the first embodiment, thereby enabling more accurate location display.

On the other hand, when tracking the user location point of the figure map with two reference points as in the second embodiment, it may be better to use one point of the road such as an intersection or a branching point of the road rather than using the target of the reference point as an artificial structure. . This is because it is advantageous for the user to check his / her location based on the road to acquire and understand the terrain information, and the accuracy of the road guidance is improved.

FIG. 7 is a diagram schematically showing a third embodiment to which the method for displaying a location of a figure map according to the present invention is applied, and FIG. 8 is a view of a map to which the third embodiment including the first and second embodiments is applied. One of the drawings will be described with reference to this.

3) Third embodiment

As shown in FIG. 7 and FIG. 8, the position tracking module 310 selects three reference values in the reference value GPS coordinate checking step S30 and sets the coordinates to the first, second, and third reference points RSP1 and RSP2, respectively. , RSP3, RDP3 ') and the distance between the four points RSP1, RSP2, RSP3, and RSP3'RP, using the coordinates of the user transmitted from the GPS 100 as the user location point RP, RD1, RD2, RD3, RD3 ').

At this time, the distance (RD1, RD2, RD3, RD3 ') is to check the ratio of the three distances (RD1, RD2, RD3, RD3') as in the second embodiment and apply it to the picture map.

As a result, the distance satisfying the ratio based on the first, second, and third reference points SP1, SP2, and SP3 of the figure map corresponding to the first, second, and third reference points RSP1, RSP2, RSP3, and RSP3 '. The user location point P of D1, D2, D3) is tracked and displayed.

In this process, the user position point P displayed on the figure map is improved in reliability relative to the position in comparison with the second embodiment, thereby enabling more accurate position display.

By the way, when three or more reference points RSP1, RSP2, and RSP3 are held, the first, second, and third reference points RSP1, RSP2, and RSP3 select the user position points RP as shown in FIG. Although it may be selected in the form of enclosing the center, as shown in Figure 7 (b), the first, second, and third (RSP1, RSP2, RSP3 ') may be selected in a form that does not surround the user location point (RP) Can be.

As a result, when the user location point RP displayed on the electronic map is displayed as the user location point P of the figure map as in the latter case, the first, second, and third reference points RSP1, RSP2, and RSP3 deviate from each other. Since other parts (points) have no influence during the process of determining the user location point (P) of the picture map, the user location point (P) displayed on the picture map may be different from the actual location point (RP). have. Of course, the user will have a hard time understanding their location displayed on the map.

Therefore, when selecting the reference point, it is preferable to make the place surrounding the user location point RP as possible as the reference point, so that the reference point is positioned as shown in FIG. To this end, when setting the first, second and third reference points RSP1, RSP2 and RSP3, it may be desirable to prevent the triangle formed by the first, second and third reference points RSP1, RSP2 and RSP3 from becoming obtuse triangles. . As a result, a triangle having vertices of the first, second, and third reference points RSP1, RSP2, and RSP3 may be an acute triangle or a right triangle.

9 is a view schematically showing the fourth and fifth embodiments to which the method of displaying a location of a figure map according to the present invention is applied.

4) Fourth embodiment

As shown in FIG. 9, the position tracking module 310 selects four reference values in the reference value GPS coordinate checking step S30 and sets the coordinates to the first, second, third, and fourth reference points RSP1, RSP2, and RSP3, respectively. , RSP4) and the distance (RD1, RD2, RD3, RD4) between the five points (RSP1, RSP2, RSP3, RSP4, RP) using the coordinates of the user transmitted from the GPS 100 as the user location point (RP). Calculate

At this time, the distance (RD1, RD2, RD3, RD4) is to check the ratio of the three distances (RD1, RD2, RD3, RD4) as in the second embodiment and apply it to the picture map.

As a result, the ratio is based on the first, second, third, and fourth reference points SP1, SP2, SP3, and SP4 of the figure map corresponding to the first, second, third, and fourth reference points RSP1, RSP2, RSP3, and RSP4. The user location point (P) of the distance (D1, D2, D3, D4) that satisfies is tracked and displayed.

In this process, the user position point P displayed on the figure map is improved in reliability relative to the position in comparison with the third embodiment, thereby enabling more accurate position display.

 FIG. 10 is a view schematically showing a case where the fifth embodiment is applied to a figure map, and FIG. 11 is a view showing a position on a map for implementing the fifth embodiment, and FIG. For the implementation of the fifth embodiment is a view showing a state in which the position is displayed on the figure map, it will be described with reference to this.

5) Fifth Embodiment

A fifth embodiment of the position display method of the figure map according to the present invention is the distance between the first, second, third, fourth reference point (RSP1, RSP2, RSP3, RSP4) and the actual position point (RP) RD1, RD2, RD3 RD4) ratio of the distance between the first, second, third, and fourth reference points (RSP1, RSP2, RSP3, RSP4) divided by the reference line (Lx, Ly), rather than the process of finding the position point (P) on the figure map using the ratio. Calculate and trace the user location point (P) on the map.

That is, as shown in FIG. 9B, the distances between the four first, second, third, and fourth reference points RSP1, RSP2, RSP3, and RSP4 surrounding the user location point RP are obtained, respectively. Lx, Ly). At this time, the reference line (Lx, Ly) is a defense line pointing to the north, south, east and west centered on the user location point (RP), 'Ly' is arranged to face north and south, 'Lx' is arranged to face east and west.

Therefore, the line connecting the first reference point RSP1 and the fourth reference point RSP4 is divided into 'x1' and 'x2' by the reference line 'Ly', and the second reference point RSP2 and the third reference point RSP3 are divided. The connecting line is divided into 'x3' and 'x4' by the reference line 'Ly', and the line connecting the first reference point (RSP1) and the second reference point (RSP2) is' y1 'and' y2 by the reference line 'Lx'. The line connecting the third reference point (RSP3) and the fourth reference point (RSP4) is divided into 'y3' and 'y4' by the reference line 'Lx'.

Then, the length ratios of 'x1' and 'x2', 'x3' and 'x4', 'y1' and 'y2', 'y3' and 'y4' are checked.

Subsequently, the first, second, third and fourth reference points SP1, SP2, SP3, and SP4 of the figure map corresponding to the first, second, third, and fourth reference points RSP1, RSP2, RSP3, and RSP4, respectively, are identified. The distance between the identified reference points (SP1, SP2, SP3, SP4) is measured, and as shown in FIG. 10, 'x1' and 'x2', 'x3' and 'x4', 'y1' and 'y2', Divide the length ratio of 'y3' and 'y4' respectively.

Finally, the divided points are connected by intersection lines C1 and C2, so that these intersection lines C1 and C2 intersect at one point, and the intersection points of these intersection lines C1 and C2 are illustrated. Let it be user location point P on a map.

The fifth embodiment described above is the same in that four reference points are used as reference values as in the fourth embodiment. However, there are differences in the tracking paths of the user location points P displayed on the figure map using four reference points, and these differences show the following differences.

First, in the fourth embodiment, the distance between the four reference points and the user location points RP is applied to the picture map to calculate and track the user location point P of the picture map. Only four variable factors are used to compute and track P). However, in the fifth embodiment, the distance (4) between each reference point and the length ('x1' and 'x2', 'x3' and 'x4' and 'y1' divided by the distance by the reference lines (Lx and Ly)). And 'y2', 'y3' and 'y4'), a total of eight variable factors are used to find the user location point (P) of the map.

Therefore, even though the scale ratio is not relatively constant and the illustrated arrangement position of a particular artificial structure or road is somewhat different from the actual topographic information, the actual topographic information is flexibly applied according to the illustrated state of the figure map, so that the user's position is more accurate. The point P can be displayed.

For reference, in order to efficiently apply the fourth and fifth embodiments, the selected first, second, third, and fourth reference points RSP1, RSP2, RSP3, and RSP4 are divided into reference lines Lx and Ly. It should be arranged in four spaces (northwest space, southwest space, southeast space, northeast space).
