Abstract

Disclosed is a system and method for providing position information by using a mini-map, the system including: a server for detecting and transmitting an image including an entire field and position information of at least one athlete and a ball; and a mobile communication terminal for displaying the image received from the server, and displaying the position information of the at least one athlete and the ball on a mini-map.

Claims

1. A system for providing position information by using a mini-map, the system comprising:

a server for detection and transmission of an image including an entire field and determination of calculated position information of at least one athlete and a ball therein; and

a mobile communication terminal for receipt and display of the image transmission from the server, and for display of the calculated position information of the at least one athlete and the ball on the mini-map.

2. The system as claimed in claim 1, wherein the server comprises:

a position detector for determination of calculated position information on the mini-map according to movements of the at least one athlete and the ball from an entire length of the field photographed by a camera unit by using a method selected from the group consisting of an absolute position display method for displaying actual coordinates of the at least one athlete and the ball on the mini-map and a relative position display method for displaying positions of the at least one athlete and the ball at a relative ratio on the mini-map; and

a wireless transmission unit for transmission of the calculated position information to the mobile communication terminal.

3. The system as claimed in claim 2, wherein the server further comprises a key input unit by which a user selects one display method from the group consisting of the absolute position display method and the relative position display method.

4. The system as claimed in claim 1, wherein the mobile communication terminal comprises:

an image processor for providing a mini-map for displaying thereon the calculated position information according to movements of the at least one athlete and the ball, the position information being received from the server;

a controller for recalculating the position information of the at least one athlete and the ball according to positions and sizes of the mini-map provided by the image processor; and

a display unit for displaying the recalculated position information of the at least one athlete and the ball on the mini-map.

5. The system as claimed in claim 4, wherein the image processor provides the mini-map based on a screen size of the display unit according to shapes and sizes thereof requested by a user.

6. The system as claimed in claim 4, wherein the controller recalculates the position information of the at least one athlete and the ball based on a display method selected from the group consisting of the absolute position display method or the relative position display method.

7. The system as claimed in claim 6, wherein when position information as a set of coordinate values calculated through the selected display method is received by the controller, the controller recalculates the positions of the at least one athlete and the ball in consideration of positions and sizes of a provided mini-map such that a display unit displays the image including the entire soccer field and the positions of the at least one athlete and the ball according to the movement of the at least one athlete and the ball on the mini-map.

8. The system as claimed in claim 7, wherein the controller controls the display unit to display the calculated position information of the at least one athlete and the ball by using dots or shapes desired by a user.

9. The system as claimed in claim 6, wherein the controller controls the display unit to display the calculated position information of the at least one athlete and the ball by using dots or shapes desired by a user.

10. The system as claimed in claim 4, wherein the mobile communication terminal displays the calculated position information displayed on the mini-map on a screen of an external display device through an interface unit.

11. A method for providing position information by using a mini-map, the method comprising the steps of:

inputting by a server an image including an entire field photographed through a camera;

calculating actual positions of at least one athlete and a ball as coordinate values based on movement of the at least one athlete and the ball from the photographed image through a method selected from the group consisting of an absolute position display method and a relative position display method;

transmitting the photographed image including the entire field and calculated position information based on the movement of the at least one athlete and the ball to a mobile communication terminal;

receiving by the mobile communication terminal the photographed image and the calculated position information;

outputting the received image at a full size of a screen, and providing a mini-map based on sizes of the screen according to shapes and sizes requested by a user;

recalculating the position information of the at least one athlete and the ball through a display method selected from the group consisting of the absolute position display method and the relative position display method in consideration of positions and sizes of the mini-map; and

displaying the image and the calculated positions of the at least one athlete and the ball on the mini-map based on the movements of the at least one athlete and the ball.

12. The method as claimed in claim 11, further comprising a step of displaying the position information of the at least one athlete and the ball by using dots or shapes selected by a user.
