Abstract:
Provided is a calibration apparatus and method of a three-dimensional (3D) position and direction estimation system. The calibration apparatus may receive inertia information and intensity information during a predetermined period of time, may calculate distances between a transmitter and the respective receivers, and may calibrate a signal attenuation characteristic of each receiver using the distances between the transmitter and the respective receivers.
