METHOD AND APPARATUS FOR RECOGNIZING INDOOR LOCATION USING RECEIVED SIGNAL STRENGTH INTENSITY MAP

摘要

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.

1. An apparatus for recognizing an indoor location using an RSSI (Received Signal Strength Intensity) map, the apparatus comprising:
an environment information acquirer configured to acquire indoor environment information and store the acquired indoor environment information on a node basis in the form of one package; a numerical map creator configured to create a numerical map that represents physical locations of surrounding objects that are present on a spatial structure or a space in numerical values using the indoor environment information acquired by the environment information acquirer; a field intensity creator configured to create the RSSI map which is map information in which received signal strength indication (RSSI) information measured by a wireless communication module is stored on a spatial location or area basis; a dead-reckoning sensor configured to locate an area less than several meters within which the environment information acquire is actually located through the use of the radio signal strength indication information and to locate a more accurate location within the area; a path information producer configured to produce path information which is information including movable potential trajectories when an arbitrary fingerprint moves to another fingerprint; and an initializer configured to initialize an initialization location of one or more candidate entities and fingerprint information that is affiliated to the candidate entities.
