摘要
The present invention relates to integrated localization method and apparatus of high accuracy, and estimates a relative position of a moving node, based on motion sensing of the moving node, estimates an absolute position of the moving node, based on a change pattern of at least one signal strength received from at least one fixed node over a plurality of time points, calculates accuracy of the absolute position of the moving node that changes along a movement route of the moving node, and determines a current position of the moving node from at least one of the relative position and the absolute position estimated as such in accordance with the accuracy of the absolute position of the moving node. Accordingly, it is possible to accurately estimate a position of a moving node using a radio signal which not only accurately estimates the position of the moving node even in a change of wireless environment or various route changes but also has almost no change in signal strength over a wide region.
