Abstract

A method and apparatus for providing point of interest (POI) information of a mobile terminal are disclosed to extract and provide POI information and/or road information included in an image captured by a camera. Location information of an image capture place and image capture direction information are read from the digital photo image, the POI information corresponding to the location and image capture direction information is extracted from map data, and the extracted POI information is displayed on the digital photo image.

Claims

1. A method for providing Point of Interest (POI) information of a mobile terminal, the method comprising:

reading image capture location information and image capture direction information from a digital photo image;

extracting POI information corresponding to the image capture location information and image capture direction information from stored map data;

displaying the extracted POI information on the digital photo image; and

selecting, in response to user input, a location corresponding to the displayed POI information as a destination.

2. The method of claim 1, further comprising:

reading image location altitude information and image capture angle information from the digital photo image,

wherein the step of extracting comprises extracting the POI information based on the read image location altitude information and image capture angle information.

3. The method of claim 1, wherein the step of displaying comprises:

matching the extracted POI information to the digital photo image.

4. The method of claim 1, further comprising:

recording the extracted POI information on the digital photo image.

5. The method of claim 1, wherein the step of extracting of the POI information comprises:

determining whether or not any POI information corresponding to the image capture location information and image capture direction information is included in the stored map data.

6. The method of claim 1, wherein the extracted POI information comprises road information corresponding to the image capture location information and the image capture direction information.

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

displaying one or more of a name, an address, and a phone number of a building corresponding to the extracted POI information on the digital photo image.

8. The method of claim 1, further comprising:

receiving a global positioning system (GPS) signal and generating first location data of the mobile terminal based on the received GPS signal;

generating second location data based on a travel direction of the mobile terminal and a mobile terminal speed;

generating an estimated mobile terminal location based on the first and second location data; and

providing route guidance information based on a travel path from the estimated mobile terminal location to the destination.

9. An apparatus configured to provide Point of Interest (POI) information of a mobile terminal, the apparatus comprising:

a storage unit configured to store map data; and

a controller configured to

read image capture location information and image capture direction information from a digital photo image;

extract POI information corresponding to the image capture location information and image capture direction information from the stored map data;

display the extracted POI information on the digital photo image; and

select, in response to user input, a location corresponding to the displayed POI information as a destination.

10. The apparatus of claim 9, wherein the controller is further configured to

read image location altitude information and image capture angle information from the digital photo image, and

extract the POI information based on the read image location altitude information and image capture angle information.

11. The apparatus of claim 9, wherein the controller is configured to match the extracted POI information to the digital photo image.

12. The apparatus of claim 9, wherein the controller is configured to record the extracted POI information on the digital photo image.

13. The apparatus of claim 9, wherein the controller is configured to determine whether or not any POI information corresponding to the image capture location information and image capture direction information is included in the map data.

14. The apparatus of claim 9, wherein the extracted POI information includes road information corresponding to the image capture location information and image capture direction information.

15. The apparatus of claim 9, wherein the controller is configured to display one or more of a name, an address, and a phone number of a building corresponding to the extracted POI information on the digital photo image.

16. The apparatus of claim 9, further comprising:

a GPS module configured to receive a global positioning system (GPS) signal and generates first location data of the apparatus based on the received GPS signal;

a dead-reckoning sensor configured to generate second location data based on a travel direction of the apparatus and an apparatus speed;

a map matching unit configured to generate an estimated apparatus location based on the first and second location data; and

a controller configured to provide road guidance information based on a travel path from the estimated apparatus location to the destination.

17. A motor vehicle, comprising:

an apparatus configured to provide Point Of Interest (POI) information of a mobile terminal, the apparatus including;

a storage unit configured to store map data; and

a controller configured to

read image capture location information and image capture direction information from a digital photo image;

extract POI information corresponding to the image capture location information and image capture direction information from the stored map data;

display the extracted POI information on the digital photo image; and

select, in response to user input, a location corresponding to the displayed POI information as a destination.
