The present invention relates to an electronic map, and more particularly, to a method for allowing a user to select a more accurate point on the electronic map.

Due to the rapid progress of the mobile communication industry and the technical demands, the scope of application is gradually expanding. In order to meet the user's demand, continuous technological shifts are being attempted, and in the technical trend that is gradually changing to a technology-oriented method in which user-oriented technology, that is, a technology standardization step in which hand pocket or integrated wireless technology is applied, is applied. have. Among them, a navigation system is designed in various forms and is applied to a wide range of fields by using a terminal device equipped with a GPS-only system capable of recognizing the data. The above-described navigation system is able to receive certain data from three global positioning system (GPS) satellites on earth and calculate its location based on the received data.

Figure 1a is an exemplary view showing a movement path setting method using a conventional navigation system. In FIG. 1A, a user searches as shown in FIG. 1A by using a name associated with the point to select a specific point on the electronic map, and then selects a desired point among the lists output as a search result for the search. Select. As shown in Fig. 1A, when a user searches for a specific destination, the navigation system lists the contents of the result and displays them to the user, and selects an appropriate value. Through this, the coordinate value of the list index value selected by the user is recognized, and the graphic map image value included in the coordinate value is called and displayed to the user.

Another method of selecting a specific point on the electronic map is to select the user's desired point on the electronic map displayed as an image while moving the electronic map up, down, left and right as shown in FIG. When the user selects a certain point on the electronic map displayed as an image, the navigation system calculates an actual coordinate value for the point and performs a predetermined process. In addition, the selection point is indicated by an arrow or flag. However, it was true that this conventional display method simply remained at the point confirmation level with respect to the selected point. In other words, by pointing to an arrow or flag to indicate a point of selection, it was not possible to indicate exactly where the selected point is located on the map so that the user can be fully perceived. Only guidance was possible. As a result, it was true that the boundary between the searched location value and the neighboring local area was ambiguous, so that there was considerable error and confusion when the user applied the searched location value on the map surface, and whether the selected path was set correctly. There was a limit to presenting the feedback function to the user.

Therefore, the present invention is proposed to solve the conventional problems as described above, by informing the user of the road link is selected in advance the point selected by the user before performing the search in the place where the complex road line, the user's mistake It is an object of the present invention to provide a method for selecting a point on an electronic map according to a movement path setting to prevent it in advance and to reduce driving through time reduction and error path of the point setting.

In addition, an object of the present invention is to provide a user with a more convenient route setting method and a means for selecting the correct point by guiding the user with the one-way passage and the direction of the route among the traveling route on the selected specific location.

According to an exemplary embodiment of the present invention, a method for selecting a point on an electronic map according to a moving path setting includes: a first step of displaying the electronic map; Receiving a selection of points on the electronic map from the user; Identifying link data of a road associated with the selected point; Extracting interpolation point data associated with the link data; Generating a polygonal road image using the interpolation point data; And a sixth step of displaying the polygonal road image on the electronic map in a predetermined display manner. In the first step of displaying the electronic map, the road included in the electronic map is displayed by a first display method, and the predetermined display method is a second display method that is distinguished from the first display method.

According to another example of the present invention, the polygonal road image is displayed as translucent. In addition, when the road associated with the selected point is a one-way road, the polygonal road image may be indicated by an arrow in one-way direction.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings and the contents described in the accompanying drawings, but the present invention is not limited or limited to the embodiments. Like reference numerals in the drawings denote like elements.

First, FIG. 2 is an exemplary view of a point selection method on an electronic map according to a preferred embodiment of the present invention.

As shown therein, the electronic map is first displayed to the user through a predetermined display device. The user selects a point on the electronic map for a given purpose. For example, the user may select a point on the electronicized map to set the origin, destination or waypoint in the navigation device. Of course, the user can select a point on the electronic map for other purposes as well. For example, a user may select a particular point on an electronic map to convey a map (map) for that point to friends.

If the electronic map displayed on the display device does not include the desired point, the user moves the area of the electronic map displayed on the display device up, down, left, or right to display the electronic device displayed on the display device to include the desired point. You can change the area of the map.

In Figure 2 the user selects the intersection of the dotted cross. The user moves the intersection of the cross-dotted line to the point he or she wants to select while moving the intersection of the cross-dotted line up, down, left and right, and then clicks the select button to select the desired point. For example, the user may select a destination by making the above selection on the navigation device. The present invention recognizes the actual coordinate values of the user's point set value by moving the electronic map up, down, left, and right and setting the searchable point directly on the electronic map through the user's artificial operation.

Figure 3 is an exemplary view showing a specific point on the electronic map in the form of a polybone and translucent state according to the present invention.

According to the invention, roads associated with the point selected by the user are displayed in a distinctive manner on the map. In this case, it is necessary to set a boundary area so that it can be distinguished from the surrounding image data. For this purpose, the interpolation point of the recognized link data is converted into a polybone form and displayed in a colorful state to be distinguished from the surrounding map map. . At this time, the road information included in the link data level is searched, and when the search information is identified as being a one-way road, the arrow is set separately at the end point of the link data which is converted into the polybone form and displayed. At the same time, the arrow indicates a user's redirection indication for the representative direction among the link data corresponding to the road path set up to the final destination and the link data set by the user and other link data related thereto. It is characterized by indicating the direction of movement for. Through this, the driving direction of the selected road among all the paths to be driven is a one-way straight road or a road of different characteristics, and is displayed by distinguishing the driving direction to the user. In the display step in the form of a polybone for distinguishing and displaying the displayable map information and the information of the selected specific map, it is possible to highlight only a specific driving route by distinguishing it from the premise map. By overlapping and displaying other peripheral link data related to the selected link data, the unique driving information included in the peripheral link data may be distorted, or may be displayed in a state in which the user is difficult to recognize. For this purpose, the specific link data in the converted polybone form is expressed in a translucent state and displayed separately from other surrounding map information related thereto.

4 is a flowchart of a method for selecting points on an electronic map according to a preferred embodiment of the present invention.

As shown therein, the present invention includes displaying the electronic map (S410); Selectively receiving a point (S420); Identifying link data (S430); Extracting interpolation point data (S440); Generating a road image having a polygon shape (S450); Displaying a road image (S460); Displaying a selection point (S470); It may be configured to include the step (S480) and the like for feedback for the user confirmation.

First, in step S410, the device according to the present invention displays the electronic map to the user. For example, an electronic map as shown in FIG. 2 is displayed on the device.

According to an embodiment of the present invention, a user searches as shown in FIG. 1A by using a name associated with the point to select a specific point on the electronic map, and then outputs a search result for the search. Choose the point you want. As shown in Fig. 1A, when a user searches for a specific destination, the navigation device lists the result and displays it to the user, and requests to select an appropriate value. When the user selects one item of the result content, the device calculates a coordinate value for the item selected by the user and calls and displays the electronic map image data including the location of the coordinate value to the user. To this end, the device may store the electronic map image data and coordinate values corresponding to the electronic map image data in a predetermined storage device.

According to another embodiment of the present invention, after calculating the current position where the device is located by using GPS, and displays the electronic map image data corresponding to the current position. According to another embodiment of the present invention, an electronic map image corresponding to an arbitrary position may be displayed.

In step S420, the device according to the present invention receives a selection of a point on the electronic map from the user.

The user selects a point on the electronic map for a given purpose. For example, the user may select a point on the electronicized map to set the origin, destination or waypoint in the navigation device. In this case, the device according to the present invention may receive a selection of a point on the electronic map from the user, and input to the point as one of a starting point, a waypoint and a destination for route search. Of course, the user can select a point on the electronic map for other purposes as well. For example, a user may select a particular point on an electronic map to convey a map (map) for that point to friends. If the electronic map displayed on the display device does not include the desired point, the user moves the area of the electronic map displayed on the display device up, down, left, or right to display the electronic device displayed on the display device to include the desired point. You can change the area of the map.

In FIG. 2, the intersection of the dotted crosses of the center becomes a point selected by the user. The user moves the intersection of the cross-dotted line to the point he or she wants to select while moving the intersection of the cross-dotted line up, down, left and right, and then clicks the select button to select the desired point. For example, the user may select a destination by making the above selection on the navigation device. The present invention recognizes the actual coordinate values of the user's point set value by moving the electronic map up, down, left, and right and setting the searchable point directly on the electronic map through the user's artificial operation.

In the prior art, when the user selects a point on the map, the selection of the point is regarded as correct and the next operation is performed. For example, in the case of a navigation apparatus according to the prior art, when a user selects a point selected as the destination as described above, a route is set using the point as a destination, and a route guide according to the route setting is provided. However, if a wrong point is set as a destination by a user's mistake, the user realizes that his destination setting is wrong only after driving the wrong path for a long time. The present invention is to solve this problem.

According to an embodiment of the present invention, if the accumulation is greater than a predetermined value according to the accumulation of the currently displayed electronic map, steps S420 to S460 are not performed. If the accumulation of electronic maps is large, the electronic maps do not provide the user with enough detailed information to allow the user to select a point. For example, small roads are indistinguishable when the accumulation is only about 1/100. On the other hand, if the accumulation is 1/10000, small roads are also distinguished. Such accumulation may be represented by a level such as 25M level, 50M level, 100M level, etc., which means a map capable of distinguishing up to 25M, a map capable of distinguishing up to 50M, and a map capable of distinguishing up to 100M, respectively. Therefore, when the accumulation of the electronic map is large, even if a point is set on the map, the error is too large. In this case, a predetermined guide is performed to the user without performing steps S420 to S460. Select a point on the electronic map of the appropriate accumulation.

In step S430, the device according to the invention identifies the link data of the road associated with the selected point.

Coordinate values (eg, latitude and longitude values) can be calculated for all points on the displayed electronicized map. This may be performed by storing the coordinate values of each point in a predetermined storage device or by storing the coordinate values of some points on the electronic map and calculating the coordinate values of the other points using the same. Coordinate values are calculated in the same manner for the points selected by the user.

The road displayed on the electronic map includes at least one link data. The link data has information about the coordinate values of the start point and the end point. When one road includes a plurality of link data, the start point and the end point of the plurality of link data are sequentially connected to each other to represent information on the road as a whole. In addition, the link data includes a plurality of interpolation point data. The interpolation point is to display the road more naturally when the road is displayed on the electronic map. The interpolation point is a point located between the start point and the end point of the link data. Interpolation point data includes coordinate information about the interpolation point. The link data is stored in a predetermined storage device.

Therefore, when the coordinate value of the point selected by the user on the electronic map is calculated, the link data of the road associated with the point may be identified. Link data of the road associated with the point may be link data of the road including coordinates of the point. If there is no link data of the road including the coordinate of the point, the link data of the link closest to the coordinate of the point is identified.

In step S440, the apparatus extracts interpolation point data associated with the link data.

If the link data of the road associated with the point selected by the user in step S430 is identified, interpolation point data included in the identified link data is extracted in step S440. These interpolation point data are used to generate more natural road image data in step S450.

In operation S450, the apparatus generates a polygonal road image using the interpolation point data.

When the road image is generated using the start point and the end point of the link data associated with the point selected by the user, the interpolation point data is used to generate the road image in the form of a polygon with a smooth curve.

In operation S460, the apparatus displays the polygonal road image in a predetermined display manner on the electronic map.

The predetermined display method is a second method that is distinct from the first method of displaying other roads included in the electronic map. For example, the polygonal road image may be displayed in a specific color to distinguish it from other roads. As shown in FIG. 3, the road associated with the point selected by the user is displayed prominently by the user. That is, when the user selects a point on the electronic map, the present invention displays the road associated with the selected point in a manner that the user can recognize on the map. In this way, when the user selects a point on the electronic map, the road associated with the point is characteristically displayed so that the user can easily know if the user selects the wrong point.

According to an embodiment of the present invention, when the road associated with the selected point is a one-way road, the polygonal road image is indicated by an arrow in a one-way direction. The apparatus of the present invention stores information for each road as to whether the corresponding road is a one-way road and, in the case of a one-way road, which direction the one-way road is. Then, with reference to the information, it is determined whether the road associated with the selected point is a one-way road and in which direction the one-way road is. If it is determined that the road associated with the selected point is a one-way road, the road image is illustrated by separately setting a specific direction indicating means such as an arrow in the end point portion of the link data converted and displayed in the polybone form. This example is shown in FIG. 3. Through this, the user can easily determine whether the road associated with the point selected by the user is a one-way road, and in which direction the one-way road is. This allows the user to select a new point by modifying the point selected by referring to the information on the one-way road. For example, if a user selects a particular point as a destination, but the road associated with that point is a one-way road and it does not match the desired driving route, the destination may be modified to a different point near the point originally selected. Can be.

According to another embodiment of the present invention, the polygonal road image for the link data associated with the selected point is displayed as translucent.

According to an embodiment of the present invention, the polygonal road image for the link data associated with the selected point may be displayed as non-transparent. However, in this case, due to the display characteristics of the electronic map, the display is overlapped with other peripheral link data related to the selected link data, and the color distortion phenomenon is injected into the unique driving information image included in the peripheral link data, or the user is displayed. Is displayed on the electronic map in a difficult state of recognition, it is possible to reduce the recognition range for the surrounding information. For example, a road image in the form of polygons for link data associated with the selected point is displayed in red, but other letters or images overlapping the road image may be invisible. To this end, the specific link data node displayed in the converted polybone form is displayed in a translucent state injecting recognizable color information, so that it is displayed separately from other surrounding map information related thereto. The color tone distortion phenomenon refers to a phenomenon in which the shape of the original image is hindered by impurity of one or more secondary color tones in the color tone of the original image.

In step S470, the device according to the present invention makes a predetermined mark on the selected point on the electronic map. For example, as shown in FIG. 3, an identification image such as a flag image is displayed at a point selected by the user to inform the user of the selected point.

In step S480, the device according to the present invention receives a confirmation of the point selected by the user. When the user selects a point on the electronic map, the road associated with the selected point is highlighted on the map. Therefore, the user can more clearly determine whether the point selected by the user is correct. If the selected point is correct, the user presses the "OK" button. Or, if the selected point is correct, press one of the "starting destination", "destination destination" or "stopover" for setting the route. The point is then selected and subsequent work, such as routing, is then performed. If the user realizes that the point selected by the user is not correct, the user returns to step S420 to select a new point.
