Abstract

Disclosed herein is a method for controlling an electronic apparatus, wherein the control method may include determining a bidirectional link among a plurality of links forming a map data, the bidirectional link defines a two-way road as one link; generating a virtual link by moving the determined bidirectional link based on the width of a road; and displaying a guide screen using the generated virtual link.

Claims

1. A method for calculating a real time location of an electronic apparatus on a map, comprising:

determining a bidirectional link among a plurality of links forming a map data, the bidirectional link defines a two-way road as one link;

generating a virtual link by moving the determined bidirectional link based on the width of a road; and

displaying a guide screen using the generated virtual link.

2. The method of claim 1, further comprising:

receiving a user input which requests a route guide to a destination, and

wherein the determining step determines a bidirectional link with respect to a route from the current location of a vehicle to the destination by using the map data.

3. The method of claim 2, further comprising:

generating a correction link by connecting a single direction link with respect to a route from the current location of the vehicle to the destination with the generated virtual link;

generating the route based on the generated correction link; and

wherein the displaying step displays a route guide screen which represents the vehicle identifier representing a real time location of the vehicle on the generated route.

4. The method of claim 1, wherein the determining step determines a bidirectional link among the links in a predetermined range based on the current location of the vehicle, and further comprising:

generating a correction link by connecting a single direction link in a predetermined range from the current location of the vehicle and the generated virtual link, and

wherein the displaying step displays a location guide screen which represents the vehicle identifier representing a real time location of the vehicle on the generated correction link.

5. The method of claim 1, wherein if the bidirectional link is included in the link corresponding to a Y-shaped road, the step for generating the virtual link further includes generating a virtual link which by moving the bidirectional link into the first direction by using a movement size which is determined based on the width of a road with respect to the bidirectional link, and

further comprising:

generating a correction link by connecting a virtual node of the virtual link and a node of a single direction link being close to the bidirectional link,

wherein the link corresponding to the Y-shaped road is a link wherein the bidirectional link is divided into at least two single direction links or at least two single directional links are combined into a bidirectional link.

6. The method of claim 1, wherein if the bidirectional link is included in a link corresponding to a U-turn road, the step for generating the virtual link includes generating first virtual link and second virtual link by moving the bidirectional link into first direction and second direction using the movement size which is determined based on the width of the road with respect to the bidirectional link, and

further comprising:

generating an interpolating point at a predetermined distance apart from the node of the bidirectional link; and

generating a correction link by connecting the interpolating point and the first virtual link and second virtual link.

7. The method of claim 1, wherein the displaying step includes:

generating an indicator for an augmented reality (AR); and

displaying a guide screen which displays the generated indicator through the AR.

8. An electronic apparatus, comprising:

a display unit displaying a screen;

a storing unit storing a map data;

a link generation unit, implemented on a processor operatively coupled to a memory, determining a bidirectional link, that defines a two-way road as one link, among a plurality of links forming a map data, and generating a virtual link by moving the determined bidirectional link based on the width of a road; and

a control unit controlling the display unit to display a guide screen using the generated virtual link.

9. The apparatus of claim 8, further comprising:

an input unit receiving a user input which requests a route guide to a destination, and

wherein the link generation unit determines a bidirectional link with respect to the route from the current location of the vehicle to the destination by using the map data.

10. The apparatus of claim 9, wherein the link generation unit generates a correction link by connecting a single direction link with respect to a route from the current location of the vehicle to the destination and the generated virtual link, and

11. The apparatus of claim 8, wherein the link generation unit determines a bidirectional link among the links in a predetermined range based on the current location of the vehicle and generates a correction link by connecting a single direction link in a predetermined range from the current location of the vehicle and the generated virtual link, and

the control unit controls the display unit to display a location guide screen which represents the vehicle identifier representing a real time location of the vehicle on the generated correction link.

12. The apparatus of claim 8, wherein if the bidirectional link is included in a link corresponding to a Y-shaped road, the link generation unit generates a virtual link by moving the bidirectional link in the first direction using the movement size determined based on the width of the road with respect to the bidirectional link, and generates a correction link by connecting a virtual node of the virtual link and a node of the single direction link close to the bidirectional link, and
