    • 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.
    • 提供了一种用于校正移动体的位置信息的装置和方法以及至少存储用于控制该装置的计算机程序的计算机可读记录介质。 用于校正移动体的位置信息的装置,关于移动体的位置和方位角中的至少一个的位置信息包括产生至少一个束的束发生器; 以及位置信息校正单元,其接收测量的位置信息,感测所生成的光束,并使用感测光束校正接收的测量位置信息,其中位置信息校正单元安装在移动体中。 因此,与传统的推算系统不同,可以容易地使用波束校正移动体的位置信息,并且更准确地校正位置信息而不累积误差。 此外,即使在夜间,或者当没有照明存在时,也可以在没有人造地标的情况下校正位置信息,因为使用红外线校正位置信息,并且通过增加来更准确地校正移动体的位置信息 梁的数量。 此外,可以灵活地提供光束数量和校正位置信息的精度之间的折衷,并且当移动体被拾起时允许移动体感测光束并准确地校正其位置信息 并移动到不同的位置。 因此,可以准确地校正由推算系统测量的位置和方位角中的至少一个,例如在具有本垒的家用机器人中。
