Abstract

An apparatus and method for estimating a three-dimensional (3D) position and orientation based on a sensor fusion process is provided. The method of estimating the 3D position and orientation may include estimating a strength-based position and a strength-based orientation of a remote apparatus when a plurality of strength information is received, based on an attenuation characteristic of a strength that varies based on a distance and orientation, estimating an inertia-based position and an inertia-based orientation of the remote apparatus by receiving a plurality of inertial information, and estimating a fused position based on a weighted-sum of the strength-based position and the inertia-based position, and to estimate a fused orientation based on a weighted-sum of the strength-based orientation and the inertia-based orientation. The strength-based position and the strength-based orientation may be estimated based on a plurality of adjusted strength information from which noise is removed using a plurality of previous strength information.
