Abstract: Disclosed is a low power and low memory based indoor positioning method performed by a computing device including at least one processor. The method may include: determining an operation mode to be executed based on at least one of a motion of a target and movement of the target; loading a map segment related to a current location of the target from a memory when executing a specific mode related to performing indoor positioning; and acquiring positioning data by using sensing data collected in real time for the indoor positioning, and the map segment.

Abstract: Disclosed is a low memory based indoor positioning method performed by a computing device including at least one processor. The method may include: extracting coordinate information in which a sensing value is not recorded as empty space information from map data in which each of a plurality of sensing values measured in a plurality of coordinates is recorded; generating a sensing value array including the plurality of sensing values; and storing the empty space information and the sensing value array in a memory.
