Abstract

Disclosed herein is a control method of an electronic apparatus. The control method of an electronic apparatus includes: determining a position of a vehicle that is being operated; detecting information of a guidance point positioned in front of the determined position of the vehicle by a predetermined distance using a map data; generating an object indicating the guidance point using the information of the guidance point; and outputting the generated object through augmented reality.

First claim

What is claimed is:

1 . A control method of an electronic apparatus, comprising:
determining a position of a vehicle that is being operated; detecting information of a guidance point positioned in front of the determined position of the vehicle by a predetermined distance using a map data; generating an object indicating the guidance point using the information of the guidance point; and outputting the generated object through augmented reality.

2 . The control method of an electronic apparatus of claim 1 , wherein the outputting includes:
performing calibration on a camera to calculate camera parameters; generating a virtual three-dimensional (3D) space for a photographed image of the camera on the basis of the camera parameters; and mapping the generated object to the virtual 3D space.

3 . The control method of an electronic apparatus of claim 2 , wherein the outputting further includes:
calculating position difference information between the position of the vehicle and a position of the guidance point; and determining a position of the generated object on the virtual 3D space using the position difference information.

4 . The control method of an electronic apparatus of claim 3 , wherein the object includes a first object indicating the position of the guidance point in augmented reality corresponding to a real world.

5 . The control method of an electronic apparatus of claim 4 , wherein an expression position of the first object is fluidly changed depending on a distance difference between the vehicle and the guidance point.

6 . The control method of an electronic apparatus of claim 1 , wherein when the vehicle passes through the guidance point, an object indicating the guidance point through which the vehicle passes disappears from the augmented reality.

7 . The control method of an electronic apparatus of claim 4 , wherein the object further includes a second object guiding the guidance point.

8 . The control method of an electronic apparatus of claim 1 , wherein the outputting is activated when the vehicle enters a point within a preset distance from the guidance point while being operated.

9 . The control method of an electronic apparatus of claim 1 , wherein in the case in which the guidance point is implemented as a guidance section including a guidance start point and a guidance end point,
in the generating, an object guiding the guidance section is generated using information of the guidance start point and the guidance end point, and in the outputting, the generated object is output through the augmented reality during a period in which the vehicle is positioned in the guidance section.

10 . An electronic apparatus comprising:
a display unit displaying a screen; a detecting unit detecting information of a guidance point positioned in front of a position of a vehicle that is being operated by a predetermined distance using a map data; an object generating unit generating an object indicating the guidance point using the information of the guidance point; and a control unit controlling the display unit to display the generated object through augmented reality.

11 . The electronic apparatus of claim 10 , further comprising:
a calibration unit performing calibration on a camera to calculate camera parameters; a 3D space generating unit generating a virtual 3D space for a photographed image of the camera on the basis of the camera parameters; and a mapping unit mapping the generated object to the generated virtual 3D space.

12 . The electronic apparatus of claim 11 , wherein the control unit calculates position difference information between the position of the vehicle and a position of the guidance point, and determines a position of the generated object on the virtual 3D space using the position difference information.

13 . The electronic apparatus of claim 12 , wherein the object includes a first object indicating the position of the guidance point in augmented reality corresponding to a real world.

14 . The electronic apparatus of claim 13 , wherein an expression position of the first object is fluidly changed depending on a distance difference between the vehicle and the guidance point.

15 . The electronic apparatus of claim 10 , wherein when the vehicle passes through the guidance point, an object indicating the guidance point through which the vehicle passes disappears from the augmented reality.

16 . The electronic apparatus of claim 13 , wherein the object further includes a second object guiding the guidance point.

17 . The electronic apparatus of claim 10 , wherein expression of the object in the augmented reality is activated when the vehicle enters a point within a preset distance from the guidance point while being operated.

18 . The electronic apparatus of claim 10 , wherein in the case in which the guidance point is implemented as a guidance section including a guidance start point and a guidance end point,
the object generating unit generates an object guiding the guidance section using information of the guidance start point and the guidance end point, and the control unit controls the display unit to display the generated object through the augmented reality during a period in which the vehicle is positioned in the guidance section.

19 . A computer program stored in a recording medium coupled to an electronic apparatus to execute the following steps:
determining a position of a vehicle that is being operated; detecting information of a guidance point positioned in front of the determined position of the vehicle by a predetermined distance using a map data; generating an object indicating the guidance point using the information of the guidance point; and outputting the generated object through augmented reality.
