摘要： A method for indoor positioning, depending upon an embodiment of the present invention, comprises the steps of: setting node data including information regarding the location of a positioning sensor on a movement path of a moving object with respect to an indoor space; obtaining first positioning data capable of determining a first section in which the moving object is currently located, by using at least one of the node data, first sensing data obtained through a sensor unit provided in the moving object, and second sensing data obtained through the positioning sensor; determining whether the first positioning data satisfies a preset reference value for a boundary node defining the first section; and determining subsequent positioning data of the first positioning data on the basis of at least one of the node data, information indicating whether the reference value is satisfied, and information indicating whether the boundary node rotates.

摘要： A screen display method depending upon one embodiment of the present invention comprises: a step for setting, for an indoor space, depending upon a preset rule on a movement path on which a moving object can move, node data comprising information about the location of a positioning sensor; a first display step for, on the basis of first positioning data of a first point of the moving object, generating and displaying a first correction UI moving in a first direction in which the moving object moves, the first correction UI being displayed in a corrected speed compared to the actual speed of the moving object from a first start node to a first end node; and a step for determining a succeeding display step by determining whether the moving object rotates at the first end node.

摘要： 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.
