    摘要: A localization method and localization device of a mobile robot is provided. In one aspect, characteristic information of a reference object is stored in advance to be used as a landmark for localization, and reference characteristic information is defined by utilizing the stored characteristic information and characteristic information obtained at an initial location of the mobile robot. Therefore, the accuracy of localization can be increased without the use of additional artificial landmarks.

    摘要: An obstruction-determining apparatus for preventing a mobile robot from being obstructed in a niche and a boundary-estimation method and medium using the obstruction-determining apparatus are disclosed. More particularly, an obstruction-determining apparatus which can determine whether a mobile robot is obstructed in a niche, and enable a mobile robot to easily escape from an obstacle if the mobile robot is determined to be obstructed in the niche, and a boundary-estimation method and medium for estimating the boundaries of an obstacle with a niche using the obstruction-determining apparatus. The obstruction-determining apparatus includes a contact module which collides with an obstacle above the mobile robot, a contact-operating module which rotates or moves linearly as a result of the collision between the contact module and the obstacle, and a sensing module which detects the rotation or the linear movement of the contact-operating module and determines whether the mobile robot is obstructed in a niche.

    摘要: A method and apparatus for tracking an image considering scale are provided. A registered image patch may be divided into a scale-invariant image patch and a scale-variant image patch according to a predetermined scale invariance index (SII). If a registered image patch within an image is a scale-invariant image patch, the scale-invariant image patch is tracked by adjusting its position, while if the registered image patch is a scale-variant image patch, the scale-invariant image patch is tracked by adjusting its position and scale.
