Abstract

Provided are a method and apparatus for detecting a position of an object using radio frequency identification (RFID). The method includes calculating a position of a moving object using a first RFID tag installed at a particular position in a predetermined space while the moving object is moving, sensing a second RFID tag included in the object, determining the position of the object as the position calculated at a point of time when the RFID tag included in the object is sensed, and displaying the determined position.

Claims

1. A method of detecting a position of an object using a moving object, the method comprising:

calculating a position of the moving object using a first radio frequency identification (RFID) tag installed at a position in a predetermined space;

sensing a second RFID tag included in the object; and

determining the position of the object based on the position of the moving object calculated at a point of time when the second RFID tag is sensed.

2. The method of claim 1, wherein at least one of the calculating the position of the moving object and the sensing the second RFID tag is performed while the moving object is moving in the predetermined space.

3. The method of claim 1, further comprising displaying the determined position of the object.

4. The method of claim 3, further comprising receiving information stored in the second RFID tag when the second RFID tag is sensed,

wherein the displaying the determined position of the object comprises displaying the determined position of the object and the received information.

5. The method of claim 4, further comprising:

receiving input information about the object from a user; and

storing the input information in the second RFID tag,

wherein the information stored in the second RFID tag comprises the received input information.

6. The method of claim 1, wherein the position of the moving object is calculated using at least one of an odometry method and the first RFID tag.

7. A method of detecting a position of an object using a moving object, the method comprising:

receiving input information related to the object;

sensing an RFID tag included in the object while the moving object is moving; and

providing an indication that the object is detected if information stored in the sensed RFID tag corresponds to the received input information.

8. The method of claim 7, further comprising discontinuing movement of the moving object if the information stored in the sensed RFID tag corresponds to the received input information.

9. The method of claim 7, wherein the indication is ringing an alarm.

10. An apparatus for detecting a position of an object using a moving object, the apparatus comprising:

a control unit which calculates a position of the moving object using a first radio frequency identification (RFID) tag installed at a position in a predetermined space, while the moving object is moving in the predetermined space; and

an RFID reader which senses a second RFID tag included in the object, while the moving object is moving,

wherein the control unit determines the position of the object as the position of the moving object calculated at a point of time when the second RFID tag is sensed.

11. The apparatus of claim 10, further comprising a display unit which displays the determined position of the object.

12. The apparatus of claim 11, wherein the RFID reader receives information stored in the second RFID tag when the second RFID tag is sensed, and the display unit displays the determined position of the object and the received information.

13. The apparatus of claim 12, further comprising a user input unit which receives input information about the object from a user and provides the received input information to the second RFID tag, wherein the information stored in the second RFID tag comprises the received input information.

14. The apparatus of claim 10, wherein the moving object is a robotic vacuum cleaner.

15. The apparatus of claim 10, wherein the control unit calculates the position of the moving object using at least one of an odometry method and the first RFID tag.

16. An apparatus for detecting a position, wherein the apparatus detects a position of an object using a moving object, the apparatus comprising:

a user input unit which receives input information about the object from a user;

an RFID reader which senses an RFID tag included in the object, while the moving object is moving; and

a control unit which informs the user that the object is detected, if information stored in the sensed RFID tag corresponds to the received input information.

17. The apparatus of claim 16, wherein the control unit discontinues movement of the moving object if the information stored in the sensed RFID tag corresponds to the received input information.

18. The apparatus of claim 16, wherein the control unit informs the user that the object is detected by ringing an alarm.

19. The apparatus of claim 16, wherein the moving object is a robotic vacuum cleaner.

20. A computer readable medium having embodied thereon a computer program for executing a method of detecting a position of an object using a moving object, the method comprising:

calculating a position of the moving object using a first radio frequency identification (RFID) tag installed at a position in a predetermined space;

sensing a second RFID tag included in the object; and

determining the position of the object based on the position of the moving object calculated at a point of time when the second RFID tag is sensed.
