Apparatus and method for correcting location information of mobile body, and computer-readable media storing computer program for controlling the apparatus
First Claim
1. An apparatus for correcting location information of a mobile body, the location information being at least one of a location and an azimuth angle of the mobile body, the apparatus comprising:
- a beam generator generating at least one beam; and
a location information correcting unit receiving measured location information, sensing the generated beam, and correcting the received measured location information using the sensed beam, wherein the location information correcting unit is installed in the mobile body.

Abstract
There is provided an apparatus and method for correcting location information of a mobile body and a computer-readable recording medium storing at least a computer program for controlling the apparatus. The apparatus for correcting the location information of the mobile body, the location information regarding at least one of a location and an azimuth angle of the mobile body, includes a beam generator generating at least one beam; and a location information correcting unit receiving measured location information, sensing the generated beam, and correcting the received measured location information using the sensed beam, wherein the location information correcting unit is installed in the mobile body. Therefore, it is possible to easily correct location information of a mobile body using beams and more accurately correct the location information without accumulating errors, differently from a conventional dead reckoning system. Also, it is possible to correct the location information without an artificial landmark, even at night, or when no lighting exists, since the location information is corrected using an infrared ray, and to more accurately correct the location information of a mobile body by increasing the number of the beams. Further, it is possible to flexibly provide a trade-off between the number of the beams and accuracy in correcting of the location information, and to allow the mobile body to sense beams and accurately correct its location information, when the mobile body is picked up and moved to a different location. Therefore, it is possible to accurately correct at least one of a location and an azimuth angle measured by the dead reckoning system, for example, in a home robot having a home base.
