    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.

    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.
