Abstract
An indoor positioning method includes judging whether a positioning terminal enters a coverage range of a virtual beacon. If yes, judging whether a distance between the positioning terminal and the virtual beacon gradually decreases to obtain a judgement result, according to the judgement result, adjusting the step size of a PDR positioning algorithm. When the distance gradually decreases, the step size of the PDR positioning algorithm is decreased, and when the distance gradually increases, the step size of the PDR positioning algorithm is increased. The positioning terminal is then positioned by a PDR positioning algorithm with the step size adjusted to obtain a positioning result. If not, the positioning terminal is positioned by a PDR positioning algorithm with the step size not adjusted to obtain a positioning result. According to the present invention positioning can be more accurate by adaptively adjusting the step size in the PDR positioning algorithm.
