Abstract: PURPOSE: A device and method for measuring indoor location are provided to improve precision of measurement by preventing a measurement error due to the interference of an external signal. CONSTITUTION: A device for measuring indoor location comprises a light emitting diode light, dual image sensors and a controller. The light emitting diode light receives position signals and converts them to light signal. The dual image sensor is installed in order to be separated with the light emitting diode light. The dual image sensor output an electric signal after receiving optical signal. The controller receives the outputted electric signal from the dual image sensor. The controller gets the location information of a plurality of light emitting diodes. The controller produces the coordinate of the target position by using the location information of obtained multiple light emitting diodes.
