Method and apparatus for recognizing indoor location using received signal strength intensity map
An apparatus for recognizing an indoor location using an RSSI (Received Signal Strength Intensity) map, includes an environment information acquirer configured to acquire indoor environment information and store the acquired indoor environment information on a node basis; a numerical map creator configured to create a numerical map; a field intensity creator configured to create the RSSI map; a dead-reckoning sensor configured to locate an area less than several meters within which the environment information acquire is actually located to locate a more accurate location within the area; a path information producer configured to produce path information including movable potential trajectories; and an initializer configured to initialize an initialization location of one or more candidate entities and fingerprint information.
