Patent ID: 8624707

Claim:
A detection target identifying/position estimating system, comprising: at least one area-fixed transmitting device not affixed to a detection target and installed in at least one predetermined position a target area, each area-fixed transmitting device transmitting identification information for determining antecedents of the area-fixed transmitting device, with radio communication; at least one detection-target transmitting device affixed to the detection target, each detection-target transmitting device transmitting the identification information for determining antecedents of the at least one detection-target transmitting device, with radio communication; at least one receiving device installed in said target area, each receiving device for receiving the identification information transmitted from said at least one area-fixed transmitting device with radio communication to measure a reception intensity thereof; and for receiving the identification information transmitted from said at least one detection-target transmitting device with radio communication; a reference pattern database configured to store a reference position for an object within the target area and a reference reception pattern, the reference reception pattern comprising signal intensities received from the at least one area-fixed transmitting device and the at least one detection-target transmitting device, respectively, when the object is located at the reference position, said reference position and the reference reception pattern being correspondingly stored; a position estimating means for acquiring a reception pattern comprising the signal intensities received from the at least one area-fixed transmitting device and the at least one detection-target transmitting device, respectively, and for retrieving the reference position which corresponds to the reference pattern acquired, the correspondence being determined by a comparison between a received reception pattern and each reference reception pattern from the reference pattern database and for estimating a position of the detection target within the target area from the retrieved reference position;—and an identification information/object position correspondence means that causes the identification information transmitted from the detection-target transmitting device and received by the at least one receiving device, and said estimated position of the object to correspond to each other.
