Abstract

For providing personalized intelligent services to users, 3 dimensional indoor positioning technology to recognize the position of person and equipment becomes important. In this paper, the acoustic signal generated from the proliferated smart phone is received from the 5 microphones equipped in the front panel of 3D positioning system, and the two proposed methods estimate the 3D coordinate of the smart phone, and finally it is verified using the implemented experimental system.

사용자 맞춤형의 지능화 서비스를 위해 실내에서 사용자 및 기기들의 3차원 위치를 인식하는 기술에 대한 중요성이 급증하고 있다. 본 논문에서는 최근 들어 폭발적으로 활성화된 스마트폰에서 음향신호를 발생하고 5개의 마이크들을 십자 형태로 동일 평면상에 배치한 3차원 위치 측정 장치에서 TDOA 방식을 적용하여 스마트폰의 3차원 위치 좌표를 추정하는 2가지 방식을 제안하고 실험적으로 검증하였다.
