Abstract
Embodiments of the present disclosure provide an indoor positioning method for measuring a location of a mobile terminal using the mobile terminal and a plurality of positioning sensors communicating therewith. The indoor positioning method includes selecting a period for acquiring sensor information related to a relationship between the mobile terminal and the positioning sensors; acquiring a variable group corresponding to a positioning sensor selected from among the plurality of positioning sensors for each of unit periods of the selected period, the sensor information being acquired from the plurality of positioning sensors; applying a probability inference method to the variable group; and acquiring a final location of the mobile terminal based on the probability inference method, wherein the sensor information comprises signal strengths received by the mobile terminal from the positioning sensors, and a unique identification of the positioning sensors.
